Signal Recognition Signal Recognition Particle-Receptor Complex Structure Solved Signal Recognition Particle-Receptor Complex Structure Solved Print Monday, 27 February 2012 15:06 The signal recognition particle (SRP) is a ubiquitous ribonucleoprotein (RNP) complex that delivers membrane and secretory proteins to the cell membrane in prokaryotes and in eukaryotes to the endoplasmic reticulum (ER), an organelle that forms a network of protein and lipid synthesizing factories. This process, called co-translational protein targeting, is an essential and evolutionarily conserved pathway for delivering nascent proteins to the eukaryotic ER. To learn more about co-translational protein targeting, researchers from UC Berkeley and the Swiss Federal Institute of Technology collaborated to determine the crystal structure of the prokaryotic SRP:SR complex arrested in the cargo release state at 3.9 Å resolution.

SciTech Connect (OSTI)

There is growing interest in using tumor associated antigens presented by class I major histocompatibility complex (MHC-I) proteins as cancer vaccines. As native peptides are poorly stable in biological fluids, researchers have sought to engineer synthetic peptidomimetics with greater biostability. Here, we demonstrate that antigenic peptidomimetics of the Melan-A/MART-1{sub 26(27L)-35} melanoma antigen adopt strikingly different conformations when bound to MHC-I, highlighting the degeneracy of T cell recognition and revealing the challenges associated with mimicking native peptide conformation.

SciTech Connect (OSTI)

Microsensors do not have the selectivity to chemical species available in large laboratory instruments. This project employed arrays of catalytically gated silicon microsensors with different catalysts to create data streams which can be analyzed by pattern recognition programs. One of the most significant accomplishments of the program was the demonstration of that mixtures of H{sub 2} with the oxidants NO{sub x} and O{sub 2} could distinguished from one another by the use of different catalytic metals on the Sandia Robust Hydrogen (SRH) sensors and the newly developed pattern recognition algorithm. This sensor system could be used to identify explosive gas mixtures and analyze exhaust streams for pollution control.

Substrate Recognition Strategy for Botulinum Neurotoxin

Substrate Recognition Strategy Substrate Recognition Strategy for Botulinum Neurotoxin Substrate Recognition Strategy for Botulinum Neurotoxin Print Wednesday, 25 May 2005 00:00 Clostridal neurotoxins (CNTs) are the causative agents of the neuroparalytic diseases botulism and tetanus. By inhibiting release of the neurotransmitter acetylcholine, for example, the neurotoxin produced by the bacterium Clostridium botulinum interferes with nerve impulses and causes a paralysis of respiratory and skeletal muscles that can cause death. Researchers from Stanford University have now determined the first structure of a CNT in complex with its target. The structure at a resolution of 2.1 Å, together with enzyme kinetic data, reveals an array of active sites (exosites) that give the CNT its deadly specificity.

Botulism Toxin The best thing one can say about botulism is that it is relatively rare. At worst, botulism can ultimately result in death due to respiratory failure resulting from paralysis of the muscles used in breathing. The muscle paralysis is caused by the neurotoxin produced by the bacterium Clostridium botulinum, which can be ingested with contaminated food, enter the body through wounds, or (in the case of infants where there is little competition from other microbes) germinate in the intestine from spores. Given early after onset of symptoms, an antitoxin exists that can prevent further damage, but a more effective treatment for this and other neurotoxin-caused illnesses, such as tetanus, await a more detailed understanding of how the toxin works at the molecular level.

Soviet image pattern recognition research  

SciTech Connect (OSTI)

This report is an assessment of the published Soviet image pattern recognition (IPR) research and was written by a panel of six US academic experts in that research field. Image pattern recognition is a set of technological research topics involving automatic or interactive computer processing of pictorial information, utilizing optical, electronic, and computer technologies. This report focuses on IPR system configuration (optical, hybrid, digital), and current research. The topical chapter headings are Image Processing Hardware and Software Preprocessing, Statistical Pattern Recognition, Computer Vision, and Optical Techniques and Systems. Soviet research in all areas of IPR is strong in theory, but limited by poor availability of equipment for generating and handling digital images, and digital computer hardware and software. Nevertheless, some Soviet IPR achievements compare favorably with those of the West. There is strong Soviet research in statistical pattern recognition, where fundamental relationships related to the factors determining error rates in classification of images are being developed. There has been good Soviet work in enhancement and restoration of images (visible and radar) of the surface of Venus. There is a strong Soviet development program in optics and optical processing related to IPR. Nevertheless, the state of Soviet research in computer vision is ten to fifteen years behind the West, because of the lack of adequate hardware and software. The Soviet scientists in the area appear competent and knowledgeable of Western work, so that any improvement in their research output would be derived from access to more capable equipment. 402 refs., 4 figs., 4 tabs.

Abstract In this work a simple technique to obtain information about the species of wood samples using stress-wave sounds in the audible range is presented. However, spectra of wood sounds generated by pendulum impact are very complex and feature extraction for classification purposes is very difficult. Polyspectral techniques have been successfully applied to several problems from radar pattern recognition to medical signal processing. Following this approach, convolution of four different sound impacts has been done. This permits to extract clear polyspectral features suitable for wood species recognition with possible applications to both human assisted and automatic wood identification systems with minimal intersample variability. Results indicate that using this technique only the two most intense polyspectral peaks are enough for species recognition.

Fuzzy Logic?Based Audio Pattern Recognition  

Science Journals Connector (OSTI)

Audio and audio?pattern recognition is becoming one of the most important technologies to automatically control embedded systems. Fuzzy logic may be the most important enabling methodology due to its ability to rapidly and economically model such application. An audio and audio?pattern recognition engine based on fuzzy logic has been developed for use in very low?cost and deeply embedded systems to automate human?to?machine and machine?to?machine interaction. This engine consists of simple digital signal?processing algorithms for feature extraction and normalization and a set of pattern?recognition rules manually tuned or automatically tuned by a self?learning process.

Automatic TLI recognition system, general description  

SciTech Connect (OSTI)

This report is a general description of an automatic target recognition system developed at the Idaho National Engineering Laboratory for the Department of Energy. A user`s manual is a separate volume, Automatic TLI Recognition System, User`s Guide, and a programmer`s manual is Automatic TLI Recognition System, Programmer`s Guide. This system was designed as an automatic target recognition system for fast screening of large amounts of multi-sensor image data, based on low-cost parallel processors. This system naturally incorporates image data fusion, and it gives uncertainty estimates. It is relatively low cost, compact, and transportable. The software is easily enhanced to expand the system`s capabilities, and the hardware is easily expandable to increase the system`s speed. In addition to its primary function as a trainable target recognition system, this is also a versatile, general-purpose tool for image manipulation and analysis, which can be either keyboard-driven or script-driven. This report includes descriptions of three variants of the computer hardware, a description of the mathematical basis if the training process, and a description with examples of the system capabilities.

Biometric recognition using fuzzy score level fusion  

Science Journals Connector (OSTI)

Multi-modal biometric recognition uses more than one biometric identifier to recognise a person. Identification based on multiple templates becomes an emerging need. Multi-modal biometric systems are expected to be more reliable due to the presence of multiple independent pieces of biometric traits. This paper proposes a new approach for biometric recognition using hand vein and finger vein images. Our proposed method employs hyper analytic wavelet transform and automatic thresholding techniques to extract features from the images of hand. Once the veins are extracted the location and width are stored in the database. Here score level fusion based on fuzzy logic is utilised for recognition. This approach is tested on the finger vein and hand vein databases which is containing 500 samples from 100 users. The experimental results exhibits that the proposed method is comparable with the existing recognising methods.

Chapter 9 - Recognition is Easy; Recall is Hard  

Science Journals Connector (OSTI)

Abstract This chapter describes important differences between recognition and recall, mainly that recognition is easy for the human brain and recall is hard. It describes how recognition and recall work in the brain. Patterns of neural activity, which is what memories are, can be activated in two different ways: by more perceptions coming in from the senses and by other brain activity. The former is recognition; the latter is recall. It then discusses the resulting guidelines for user-interface design, with examples.

Promiscuous Substrate Recognition in Folding and Assembly Activities of the Trigger Factor Chaperone  

SciTech Connect (OSTI)

Trigger factor (TF) is a molecular chaperone that binds to bacterial ribosomes where it contacts emerging nascent chains, but TF is also abundant free in the cytosol where its activity is less well characterized. In vitro studies show that TF promotes protein refolding. We find here that ribosome-free TF stably associates with and rescues from misfolding a large repertoire of full-length proteins. We identify over 170 members of this cytosolic Escherichia coli TF substrate proteome, including ribosomal protein S7. We analyzed the biochemical properties of a TF:S7 complex from Thermotoga maritima and determined its crystal structure. Thereby, we obtained an atomic-level picture of a promiscuous chaperone in complex with a physiological substrate protein. The structure of the complex reveals the molecular basis of substrate recognition by TF, indicates how TF could accelerate protein folding, and suggests a role for TF in the biogenesis of protein complexes.

Variable Lymphocyte Receptor Recognition of the Immunodominant Glycoprotein of Bacillus anthracis Spores  

SciTech Connect (OSTI)

Variable lymphocyte receptors (VLRs) are the adaptive immune receptors of jawless fish, which evolved adaptive immunity independent of other vertebrates. In lieu of the immunoglobulin fold-based T and B cell receptors, lymphocyte-like cells of jawless fish express VLRs (VLRA, VLRB, or VLRC) composed of leucine-rich repeats and are similar to toll-like receptors (TLRs) in structure, but antibodies (VLRB) and T cell receptors (VLRA and VLRC) in function. Here, we present the structural and biochemical characterization of VLR4, a VLRB, in complex with BclA, the immunodominant glycoprotein of Bacillus anthracis spores. Using a combination of crystallography, mutagenesis, and binding studies, we delineate the mode of antigen recognition and binding between VLR4 and BclA, examine commonalities in VLRB recognition of antigens, and demonstrate the potential of VLR4 as a diagnostic tool for the identification of B. anthracis spores.

Versatile modes of peptide recognition by the AAA+ adaptor protein SspB  

SciTech Connect (OSTI)

Energy-dependent proteases often rely on adaptor proteins to modulate substrate recognition. The SspB adaptor binds peptide sequences in the stress-response regulator RseA and in ssrA-tagged proteins and delivers these molecules to the AAA+ ClpXP protease for degradation. The structure of SspB bound to an ssrA peptide is known. Here, we report the crystal structure of a complex between SspB and its recognition peptide in RseA. Notably, the RseA sequence is positioned in the peptide-binding groove of SspB in a direction opposite to the ssrA peptide, the two peptides share only one common interaction with the adaptor, and the RseA interaction site is substantially larger than the overlapping ssrA site. This marked diversity in SspB recognition of different target proteins indicates that it is capable of highly flexible and dynamic substrate delivery.

Structural Basis for Recognition of Diubiquitins by NEMO  

SciTech Connect (OSTI)

NEMO is the regulatory subunit of the I{kappa}B kinase (IKK) in NF-{kappa}B activation, and its CC2-LZ region interacts with Lys63 (K63)-linked polyubiquitin to recruit IKK to receptor signaling complexes. In vitro, CC2-LZ also interacts with tandem diubiquitin. Here we report the crystal structure of CC2-LZ with two dimeric coiled coils representing CC2 and LZ, respectively. Surprisingly, mutagenesis and nuclear magnetic resonance experiments reveal that the binding sites for diubiquitins at LZ are composites of both chains and that each ubiquitin in diubiquitins interacts with symmetrical NEMO asymmetrically. For tandem diubiquitin, the first ubiquitin uses the conserved hydrophobic patch and the C-terminal tail, while the second ubiquitin uses an adjacent surface patch. For K63-linked diubiquitin, the proximal ubiquitin uses its conserved hydrophobic patch, while the distal ubiquitin mostly employs the C-terminal arm including the K63 linkage residue. These studies uncover the energetics and geometry for mutual recognition of NEMO and diubiquitins.

Speech Recognition, Using Analog Threshold Logic  

Science Journals Connector (OSTI)

A speech?analysis system using analog threshold logic (ATL) for feature abstraction is being developed to recognize consonants in utterances of CVC words by a number of talkers. The ATL element originally modeled after the biological neuron has an output that is linearly proportional to the net sum of excitatory and inhibitory inputs provided that this net sum is greater than some adjustable threshold. The speech?analysis system abstracts relatively steady?state as well as transient features over almost 60 dB of dynamic range from the logarithmitized outputs of 19 low?Q filters. Feature abstraction takes place in real time does not require segmentation utilizes parallel processing and provides information about both the presence and magnitude of the frequency?energy?temporal characteristics of speech sounds. Many features corresponding to results of speech?recognition experiments described in the literature have been automatically abstracted by ATL networks which measure the slope of the spectral envelope in real time. Using the experimental system recognition scores in the range of 82%99% were obtained for 16 consonants. Results for the fricative consonants are discussed and some of their invariant features described. [Work supported by the U. S.

Interactive Korean speech recognition for a mobile robot  

Science Journals Connector (OSTI)

This paper is a study on the implementation of a speech recognition mobile robot to which the interactive Korean speech recognition techniques are applied. The speech command uttered the sentential connected word and is asserted through the wireless mic system. This speech signal transferred LPC?Cepstrum and short?time energy which are computed from the received signal on the DSP board to a notebook PC. In the notebook PC the DP matching technique is used for the recognizer and the recognition results are transferred to the motor control unit which outputs pulse signals corresponding to the recognized command and drives the stepping motor. It has been implicitly assumed that for connected word recognition each word in the string can be followed by any other word in the string. However for some connected word recognition tasks there is an explicit set of rules governing which words can logically follow other words to form valid sentences in the language. In this paper a grammar network was applied to reduce the recognition speed of the recognizer so that real time recognition is realized. The misrecognized command is revised by interface revision through conversation with the mobile robot. The recognition system asks the user for help whenever there are two or more recognition candidates whose likelihood scores are all high and it is difficult to resolve small differences in the string. The recognizer asks the user to verify the first choice decision; if it is not verified the recognizer asks the user to verify the second choice etc. Alternatively the recognition system can list the confusing candidates and ask the user to choose the correct string based on the string index number in the list.

Structural Insights into RNA Recognition by the Alternate-Splicing Regulator CUG-Binding Protein 1  

SciTech Connect (OSTI)

CUG-binding protein 1 (CUGBP1) regulates multiple aspects of nuclear and cytoplasmic mRNA processing, with implications for onset of myotonic dystrophy. CUGBP1 harbors three RRM domains and preferentially targets UGU-rich mRNA elements. We describe crystal structures of CUGBP1 RRM1 and tandem RRM1/2 domains bound to RNAs containing tandem UGU(U/G) elements. Both RRM1 in RRM1-RNA and RRM2 in RRM1/2-RNA complexes use similar principles to target UGU(U/G) elements, with recognition mediated by face-to-edge stacking and water-mediated hydrogen-bonding networks. The UG step adopts a left-handed Z-RNA conformation, with the syn guanine recognized through Hoogsteen edge-protein backbone hydrogen-bonding interactions. NMR studies on the RRM1/2-RNA complex establish that both RRM domains target tandem UGUU motifs in solution, whereas filter-binding assays identify a preference for recognition of GU over AU or GC steps. We discuss the implications of CUGBP1-mediated targeting and sequestration of UGU(U/G) elements on pre-mRNA alternative-splicing regulation, translational regulation, and mRNA decay.

To help decipher the code, Ed Uberbacher and colleagues at Oak Ridge National Laboratory combined cutting- edge computer technology with their knowledge of human biology to develop GRAIL (for Gene Recognition Analysis Internet Link), a "thinking" computer program that imitates the human learning process as it searches for genetic meaning. GRAIL and successor software programs can rapidly identify key instructions in genes from within vast stretches of DNA that appear to be meaningless-a critical contribution to the

Structural Basis for Telomerase RNA Recognition and RNP Assembly by the Holoenzyme La Family Protein p65  

SciTech Connect (OSTI)

Telomerase is a ribonucleoprotein complex essential for maintenance of telomere DNA at linear chromosome ends. The catalytic core of Tetrahymena telomerase comprises a ternary complex of telomerase RNA (TER), telomerase reverse transcriptase (TERT), and the essential La family protein p65. NMR and crystal structures of p65 C-terminal domain and its complex with stem IV of TER reveal that RNA recognition is achieved by a combination of single- and double-stranded RNA binding, which induces a 105{sup o} bend in TER. The domain is a cryptic, atypical RNA recognition motif with a disordered C-terminal extension that forms an {alpha} helix in the complex necessary for hierarchical assembly of TERT with p65-TER. This work provides the first structural insight into biogenesis and assembly of TER with a telomerase-specific protein. Additionally, our studies define a structurally homologous domain (xRRM) in genuine La and LARP7 proteins and suggest a general mode of RNA binding for biogenesis of their diverse RNA targets.

Hindi phoneme-viseme recognition from continuous speech  

Science Journals Connector (OSTI)

Automatic Speech Recognition (ASR) system performs well under restricted conditions but the performance degrades under noisy environment. Audio-visual features play an important role in ASR systems in the presence of noise. In this paper, Hindi phoneme recognition system is designed using audio-visual features. The Discrete Cosine Transform (DCT) features of the lip region integrated with Mel Frequency Cepstral Coefficient (MFCC) audio features are used to get better recognition performance under noisy environments. Colour intensity, hybrid method and Pseudo-Hue methods have been used for lip-localisation approach with Linear Discriminant Analyser (LDA) as a classifier. Recognition performance using Pseudo-Hue method proved best among all the methods.

Complexity of Counting CSP with Complex Weights  

E-Print Network [OSTI]

We give a complexity dichotomy theorem for the counting Constraint Satisfaction Problem (#CSP in short) with complex weights. To this end, we give three conditions for its tractability. Let F be any finite set of complex-valued functions, then we prove that #CSP(F) is solvable in polynomial time if all three conditions are satisfied; and is #P-hard otherwise. Our complexity dichotomy generalizes a long series of important results on counting problems: (a) the problem of counting graph homomorphisms is the special case when there is a single symmetric binary function in F; (b) the problem of counting directed graph homomorphisms is the special case when there is a single not-necessarily-symmetric binary function in F; and (c) the standard form of #CSP is when all functions in F take values in {0,1}.

Inductive generation of phoneme recognition knowledge for a continuous speech recognition system SPREX  

Science Journals Connector (OSTI)

A continuous speech recognition expert system named SPREX has been constructed. It simulates the behavior of human experts who can recognize speech by inspecting the trajectories of feature parameters such as formant and power [R. Mizoguchi et al. Proc. ICASSP '86 2 12211224 (1986)]. In order to construct a speaker?independent knowledge base it is necessary to learn by concrete speech samples. ARIS (adaptive rule induction system) is developed as an inductive learning subsystem for SPREX. It has the following three characteristics that are also interesting from a knowledge of engineering point of view: (1) It can generate new attributes for separating the training samples efficiently; (2) it can cope with the noisy data problem by using heuristic generalization operators; and (3) it can deal with numerical attributes as well as symbolic ones. The latest version of a knowledge base generated by ARIS recognizes 82% of consonants and 95% of vowels. Some of these performances exceed that of the rules written by human experts.

Structure of a C-terminal fragment of its Vps53 subunit suggests similarity of Golgi-associated retrograde protein (GARP) complex to a family of tethering complexes  

SciTech Connect (OSTI)

The Golgi-associated retrograde protein (GARP) complex is a membrane-tethering complex that functions in traffic from endosomes to the trans-Golgi network. Here we present the structure of a C-terminal fragment of the Vps53 subunit, important for binding endosome-derived vesicles, at a resolution of 2.9 {angstrom}. We show that the C terminus consists of two {alpha}-helical bundles arranged in tandem, and we identify a highly conserved surface patch, which may play a role in vesicle recognition. Mutations of the surface result in defects in membrane traffic. The fold of the Vps53 C terminus is strongly reminiscent of proteins that belong to three other tethering complexes - Dsl1, conserved oligomeric Golgi, and the exocyst - thought to share a common evolutionary origin. Thus, the structure of the Vps53 C terminus suggests that GARP belongs to this family of complexes.

PHD Finger Recognition of Unmodified Histone H3R2 Links UHRF1 to Regulation of Euchromatic Gene Expression  

SciTech Connect (OSTI)

Histone methylation occurs on both lysine and arginine residues, and its dynamic regulation plays a critical role in chromatin biology. Here we identify the UHRF1 PHD finger (PHD{sub UHRF1}), an important regulator of DNA CpG methylation, as a histone H3 unmodified arginine 2 (H3R2) recognition modality. This conclusion is based on binding studies and cocrystal structures of PHD{sub UHRF1} bound to histone H3 peptides, where the guanidinium group of unmodified R2 forms an extensive intermolecular hydrogen bond network, with methylation of H3R2, but not H3K4 or H3K9, disrupting complex formation. We have identified direct target genes of UHRF1 from microarray and ChIP studies. Importantly, we show that UHRF1's ability to repress its direct target gene expression is dependent on PHD{sub UHRF1} binding to unmodified H3R2, thereby demonstrating the functional importance of this recognition event and supporting the potential for crosstalk between histone arginine methylation and UHRF1 function.

Selenophene transition metal complexes  

SciTech Connect (OSTI)

This research shows that selenophene transition metal complexes have a chemistry that is similar to their thiophene analogs. Selenophene coordination has been demonstrated and confirmed by molecular structure in both the {eta}{sup 5}- and the {eta}{sup 1}(Se)-coordination modes. The reaction chemistry of selenophene complexes closely resembles that of the analogous thiophene complexes. One major difference, however, is that selenophene is a better donor ligand than thiophene making the selenophene complexes more stable than the corresponding thiophene complexes. The {sup 77}Se NMR chemical shift values for selenophene complexes fall within distinct regions primarily depending on the coordination mode of the selenophene ligand. In the final paper, the C-H bond activation of {eta}{sup 1}(S)-bound thiophenes, {eta}{sup 1}(S)-benzothiophene and {eta}{sup 1}(Se)-bound selenophenes has been demonstrated. The deprotonation and rearrangement of the {eta}{sup 1}(E)-bound ligand to the carbon bound L-yl complex readily occurs in the presence of base. Reprotonation with a strong acid gives a carbene complex that is unreactive towards nucleophilic attack at the carbene carbon and is stable towards exposure to air. The molecular structure of [Cp(NO)(PPh{sub 3})Re(2-benzothioenylcarbene)]O{sub 3}SCF{sub 3} was determined and contains a Re-C bond with substantial double bond character. Methyl substitution for the thienylcarbene or selenylcarbene gives a carbene that rearranges thermally to give back the {eta}{sup 1}(E)-bound complex. Based on these model reactions, a new mechanism for the H/D exchange of thiophene over the hydrodesulfurization catalyst has been proposed.

This study deals with the boundary between a normal plasma of ions and electrons, and an adjacent complex plasma of ions, electrons, and microparticles, as found in innumerable examples in nature. Here we show that the matching between the two plasmas involve electrostatic double layers. These double layers explain the sharp boundaries observed in the laboratory and in astrophysics. A modified theory is derived for the double layers that form at the discontinuity between two different complex plasmas and at the point of contact of three complex plasmas. The theory is applied to the first measurements from the Plasma Kristall Experiment (PKE) Nefedov Laboratory in the International Space Station.

Mobile multiwave lidar complexes  

Science Journals Connector (OSTI)

Multiwave mobile lidar complexes (MLCs) are designed and developed. A number of vehicle-based MLCs are built. The set of complex lidar probing data obtained with the help of MLCs is synchronised in space and time, covers a large area (the operation range of an MLC is 15 km), and is based on a unified methodological approach. The results of probing contain information on the concentration and physical nature of atmospheric aerosol, chemical composition of the gaseous phase of the atmosphere, wind and turbulence. The obtained data form the basis for a complex analysis of the ecological situation and prognosis of its development.

LED Dot matrix text recognition method in natural scene  

Science Journals Connector (OSTI)

Abstract In recent years, light-emitting diodes dot-matrix text (LED text) is being widely used for displaying information and announcements. However, there is currently no text detection system that is capable of handling LED text. Unlike general printed text, it is not easy to detect and recognize LED text due to its discontinuity. A character of the LED is generally displayed with a matrix of segments and composed with them to generate the text. Furthermore, it is necessary to detect each character from a line of LED text for creating a robust text detection system. Thus, this paper proposes a method for LED text detection and recognition in natural scene images. To perform this goal of detection and recognition of a character and text, it consists of two main steps with the following steps: the first step, a Canny edge was used to detect character pixels which appear in LED display area from scene images. The center points of edge segments are calculated. These points are merged based on their properties to generate a character candidate. In order to obtain character feature, the spatial information such as a centroid and orientation of the character candidate are used. These values are then analyzed using a k-nearest neighbor approach for classifying the character candidate as a certain alphanumeric. In the second step, the recognized characters are later combined into a text line based on the similarity of their characteristics such as width, height, aspect ratio and color. The post-processing of text line generating is then applied for rectifying the falsely recognized characters. In experiments, our proposed method achieves 68.8% and 47% for detection and recognition rate, respectively. These results show the robustness and effectiveness of the proposed method for detecting and recognizing the LED text in natural scene images that has filled the vacancy that the printed and dense text detection system has not covered.

Structural Basis for Ubiquitin Recognition by the Otu1 Ovarian Tumor Domain Protein  

SciTech Connect (OSTI)

Ubiquitination of proteins modifies protein function by either altering their activities, promoting their degradation, or altering their subcellular localization. Deubiquitinating enzymes are proteases that reverse this ubiquitination. Previous studies demonstrate that proteins that contain an ovarian tumor (OTU) domain possess deubiquitinating activity. This domain of {approx}130 amino acids is weakly similar to the papain family of proteases and is highly conserved from yeast to mammals. Here we report structural and functional studies on the OTU domain-containing protein from yeast, Otu1. We show that Otu1 binds polyubiquitin chain analogs more tightly than monoubiquitin and preferentially hydrolyzes longer polyubiquitin chains with Lys{sup 48} linkages, having little or no activity on Lys{sup 63}- and Lys{sup 29}-linked chains. We also show that Otu1 interacts with Cdc48, a regulator of the ER-associated degradation pathway. We also report the x-ray crystal structure of the OTU domain of Otu1 covalently complexed with ubiquitin and carry out structure-guided mutagenesis revealing a novel mode of ubiquitin recognition and a variation on the papain protease catalytic site configuration that appears to be conserved within the OTU family of ubiquitin hydrolases. Together, these studies provide new insights into ubiquitin binding and hydrolysis by yeast Otu1 and other OTU domain-containing proteins.

Playing Tag with ANN: Boosted Top Identification with Pattern Recognition  

E-Print Network [OSTI]

Many searches for physics beyond the Standard Model at the Large Hadron Collider (LHC) rely on top tagging algorithms, which discriminate between boosted hadronic top quarks and the much more common jets initiated by light quarks and gluons. We note that the hadronic calorimeter (HCAL) effectively takes a "digital image" of each jet, with pixel intensities given by energy deposits in individual HCAL cells. Viewed in this way, top tagging becomes a canonical pattern recognition problem. With this motivation, we present a novel top tagging algorithm based on an Artificial Neural Network (ANN), one of the most popular approaches to pattern recognition. The ANN is trained on a large sample of boosted tops and light quark/gluon jets, and is then applied to independent test samples. The ANN tagger demonstrated excellent performance in a Monte Carlo study: for example, for jets with p_T in the 1100-1200 GeV range, 60% top-tag efficiency can be achieved with a 4% mis-tag rate. We discuss the physical features of the ...

Synchronization in complex networks  

SciTech Connect (OSTI)

Synchronization processes in populations of locally interacting elements are in the focus of intense research in physical, biological, chemical, technological and social systems. The many efforts devoted to understand synchronization phenomena in natural systems take now advantage of the recent theory of complex networks. In this review, we report the advances in the comprehension of synchronization phenomena when oscillating elements are constrained to interact in a complex network topology. We also overview the new emergent features coming out from the interplay between the structure and the function of the underlying pattern of connections. Extensive numerical work as well as analytical approaches to the problem are presented. Finally, we review several applications of synchronization in complex networks to different disciplines: biological systems and neuroscience, engineering and computer science, and economy and social sciences.

Conformational changes in the bacterial SRP receptor FtsY upon binding of guanine nucleotides and SRP  

Science Journals Connector (OSTI)

In cotranslational preprotein targeting in Escherichia coli, the signal recognition particle (SRP) binds to the signal peptide emerging from the ribosome and, subsequently, interacts with the signal recognition particle receptor, FtsY, at the plasma membrane. Both FtsY and the protein moiety of the signal recognition particle, Ffh, are GTPases, and GTP is required for the formation of the SRP-FtsY complex. We have studied the binding of GTP/GDP to FtsY as well as the SRP-FtsY complex formation by monitoring the fluorescence of tryptophan 343 in the I box of mutant FtsY. Thermodynamic and kinetic parameters of the FtsY complexes with GDP, GTP, and signal recognition particle are reported. Upon SRP-FtsY complex formation in the presence of GTP, the fluorescence of tryptophan 343 increased by 50 % and was blue-shifted by 10 nm. We conclude that GTP-dependent SRP-FtsY complex formation leads to an extensive conformational change in the I box insertion in the effector region of FtsY.

Lysophospholipid presentation by CD1d and recognition by a human Natural Killer T-cell receptor  

SciTech Connect (OSTI)

Invariant Natural Killer T (iNKT) cells use highly restricted {alpha}{beta} T cell receptors (TCRs) to probe the repertoire of lipids presented by CD1d molecules. Here, we describe our studies of lysophosphatidylcholine (LPC) presentation by human CD1d and its recognition by a native, LPC-specific iNKT TCR. Human CD1d presenting LPC adopts an altered conformation from that of CD1d presenting glycolipid antigens, with a shifted {alpha}1 helix resulting in an open A pocket. Binding of the iNKT TCR requires a 7-{angstrom} displacement of the LPC headgroup but stabilizes the CD1d-LPC complex in a closed conformation. The iNKT TCR CDR loop footprint on CD1d-LPC is anchored by the conserved positioning of the CDR3{alpha} loop, whereas the remaining CDR loops are shifted, due in part to amino-acid differences in the CDR3{beta} and J{beta} segment used by this iNKT TCR. These findings provide insight into how lysophospholipids are presented by human CD1d molecules and how this complex is recognized by some, but not all, human iNKT cells.

Structure of the Chloroplast Signal Recognition Particle (SRP) Receptor: Domain Arrangement Modulates SRPReceptor Interaction  

Science Journals Connector (OSTI)

The signal recognition particle (SRP) pathway mediates co-translational targeting of nascent proteins to membranes. Chloroplast SRP is unique in that it does not contain the otherwise universally conserved SRP RNA, which accelerates the association between the SRP guanosine-5?-triphosphate (GTP) binding protein and its receptor FtsY in classical SRP pathways. Recently, we showed that the SRP and SRP receptor (SR) \\{GTPases\\} from chloroplast (cpSRP54 and cpFtsY, respectively) can interact with one another 400-fold more efficiently than their bacterial homologues, thus providing an explanation as to why this novel chloroplast SRP pathway bypasses the requirement for the SRP RNA. Here we report the crystal structure of cpFtsY from Arabidopsis thaliana at 2.0 resolution. In this chloroplast SR, the N-terminal N domain is more tightly packed, and a more extensive interaction surface is formed between the \\{GTPase\\} G domain and the N domain than was previously observed in many of its bacterial homologues. As a result, the overall conformation of apo-cpFtsY is closer to that found in the bacterial SRPFtsY complex than in free bacterial FtsY, especially with regard to the relative orientation of the N and G domains. In contrast, active-site residues in the G domain are mispositioned, explaining the low basal GTP binding and hydrolysis activity of free cpFtsY. This structure emphasizes proper NG domain arrangement as a key factor in modulating the efficiency of SRPreceptor interaction and helps account, in part, for the faster kinetics at which the chloroplast SR interacts with its binding partner in the absence of an SRP RNA.

Dynamic interactions of proteins in complex networks  

SciTech Connect (OSTI)

Recent advances in techniques such as NMR and EPR spectroscopy have enabled the elucidation of how proteins undergo structural changes to act in concert in complex networks. The three minireviews in this series highlight current findings and the capabilities of new methodologies for unraveling the dynamic changes controlling diverse cellular functions. They represent a sampling of the cutting-edge research presented at the 17th Meeting of Methods in Protein Structure Analysis, MPSA2008, in Sapporo, Japan, 26-29 August, 2008 (http://www.iapsap.bnl.gov). The first minireview, by Christensen and Klevit, reports on a structure-based yeast two-hybrid method for identifying E2 ubiquitin-conjugating enzymes that interact with the E3 BRCA1/BARD1 heterodimer ligase to generate either mono- or polyubiquitinated products. This method demonstrated for the first time that the BRCA1/BARD1 E3 can interact with 10 different E2 enzymes. Interestingly, the interaction with multiple E2 enzymes displayed unique ubiquitin-transfer properties, a feature expected to be common among other RING and U-box E3s. Further characterization of new E3 ligases and the E2 enzymes that interact with them will greatly enhance our understanding of ubiquitin transfer and facilitate studies of roles of ubiquitin and ubiquitin-like proteins in protein processing and trafficking. Stein et al., in the second minireview, describe recent progress in defining the binding specificity of different peptide-binding domains. The authors clearly point out that transient peptide interactions mediated by both post-translational modifications and disordered regions ensure a high level of specificity. They postulate that a regulatory code may dictate the number of combinations of domains and post-translational modifications needed to achieve the required level of interaction specificity. Moreover, recognition alone is not enough to obtain a stable complex, especially in a complex cellular environment. Increasing evidence indicates that disordered domains can acquire structural features that modulate the binding and strength of the signaling cascade. Whereas the first two minireviews describe ways in which protein interactions are modulated, the third, by Tompa, focuses on the importance of protein disorder in a subset of amyloid proteins. It is apparent that within this group, part of the polypeptide chain remains disordered during amyloid formation. Moreover, the disordered segments have different amino acid composition and physicochemical characteristics, which suggests that they may play a role in amyloid stability. The disordered region may serve as a linker to connect the ordered core and a globular domain, maintaining the stability and structure of the globular domain and minimizing protein refolding upon amyloid formation. As techniques in protein chemistry advance, we are learning more and more about the mechanisms that regulate and are regulated by protein interactions. The three minireviews in this series offer a glimpse of the complex dynamics fundamental to protein-protein interactions. In the future, we expect that the knowledge gained will help to augment our ability to control complex pathologies and treat diverse diseases states.

RHIC Accelerators RHIC Accelerators The Relativistic Heavy Ion Collider complex is actually composed of a long "chain" of particle accelerators Heavy ions begin their travels in the Electron Beam Ion Source accelerator (1). The ions then travel to the small, circular Booster (3) where, with each pass, they are accelerated to higher energy. From the Booster, ions travel to the Alternating Gradient Synchrotron (4), which then injects the beams via a beamline (5) into the two rings of RHIC (6). In RHIC, the beams get a final accelerator "kick up" in energy from radio waves. Once accelerated, the ions can "orbit" inside the rings for hours. RHIC can also conduct colliding-beam experiments with polarized protons. These are first accelerated in the Linac (2), and further in the Booster (3), AGS (4), and

Complex pendulum biomass sensor  

DOE Patents [OSTI]

A complex pendulum system biomass sensor having a plurality of pendulums. The plurality of pendulums allow the system to detect a biomass height and density. Each pendulum has an angular deflection sensor and a deflector at a unique height. The pendulums are passed through the biomass and readings from the angular deflection sensors are fed into a control system. The control system determines whether adjustment of machine settings is appropriate and either displays an output to the operator, or adjusts automatically adjusts the machine settings, such as the speed, at which the pendulums are passed through the biomass. In an alternate embodiment, an entanglement sensor is also passed through the biomass to determine the amount of biomass entanglement. This measure of entanglement is also fed into the control system.

We compute the complexity [logarithm of the number of Thouless-Anderson-Palmer (TAP) states] associated with minima and index-one saddle points of the TAP free energy. Higher-index saddles have smaller complexities. The two leading complexities are equal, consistent with the Morse theorem on the total number of turning points, and have the value given by Bray and Moore [J. Phys. C 13, L469 (1980)]. In the thermodynamic limit, TAP states of all free energies become marginally stable.

In this work is considered a complex scalar field theory with higher order derivative terms and interactions. A procedure is developed to quantize consistently this system avoiding the presence of negative norm states. In order to achieve this goal the original real scalar high order field theory is extended to a complex space attaching a complex total derivative to the theory. Next, by imposing reality conditions the complex theory is mapped to a pair of interacting real scalar field theories without the presence of higher derivative terms.

Simultaneous recognition of HIV-1 TAR RNA bulge and loop sequences by cyclic peptide mimics of Tat protein  

SciTech Connect (OSTI)

The interaction of the HIV-1 transactivator protein Tat with its transactivation response (TAR) RNA is an essential step in viral replication and therefore an attractive target for developing antivirals with new mechanisms of action. Numerous compounds that bind to the 3-nt bulge responsible for binding Tat have been identified in the past, but none of these molecules had sufficient potency to warrant pharmaceutical development. We have discovered conformationally-constrained cyclic peptide mimetics of Tat that are specific nM inhibitors of the Tat-TAR interaction by using a structure-based approach. The lead peptides are nearly as active as the antiviral drug nevirapine against a variety of clinical isolates in human lymphocytes. The NMR structure of a peptideRNA complex reveals that these molecules interfere with the recruitment to TAR of both Tat and the essential cellular cofactor transcription elongation factor-b (P-TEFb) by binding simultaneously at the RNA bulge and apical loop, forming an unusually deep pocket. This structure illustrates additional principles in RNA recognition: RNA-binding molecules can achieve specificity by interacting simultaneously with multiple secondary structure elements and by inducing the formation of deep binding pockets in their targets. It also provides insight into the P-TEFb binding site and a rational basis for optimizing the promising antiviral activity observed for these cyclic peptides.

COMPLEX NETWORKS IN CLIMATE SCIENCE: PROGRESS, OPPORTUNITIES AND CHALLENGES  

SciTech Connect (OSTI)

Networks have been used to describe and model a wide range of complex systems, both natural as well as man-made. One particularly interesting application in the earth sciences is the use of complex networks to represent and study the global climate system. In this paper, we motivate this general approach, explain the basic methodology, report on the state of the art (including our contributions), and outline open questions and opportunities for future research. Datasets and systems that can be represented as interaction networks (or graphs), broadly defined as any collection of interrelated objects or entities, have received considerable attention both from a theoretical viewpoint as well as various application domains; examples include the analysis of social networks, chemical interactions between proteins, the behavior of financial markets, and many others. Recently, the study of complex networks - that is, networks which exhibit non-trivial topological properties - has permeated numerous fields and disciplines spanning the physical, social, and computational sciences. So why do networks enjoy such broad appeal? Briefly, it is their ability to serve at once as a data representation, as an analysis framework, and as a visualization tool. The analytic capabilities in particular are quite powerful, as networks can uncover structure and patterns at multiple scales, ranging from local properties to global phenomena, and thus help better understand the characteristics of complex systems. We focus on one particular application of networks in the earth sciences, namely, the construction and analysis of climate networks. Identifying and analyzing patterns in global climate is an important task of growing scientific, social, and political interest, with the goal of deepening our understanding of the complex processes underlying observed phenomena. To this end, we make the case that complex networks offer a compelling perspective for capturing the dynamics of the climate system. Moreover, the computational sciences - specifically data mining and machine learning - are able to contribute a valuable set of methods and tools ranging from pattern recognition to predictive models. Thus, in this paper we expand upon the general approach to climate networks and motivate a promising area of interdisciplinary research. Indeed, we believe that this marriage of analytic methods, computational tools and domain science has the long-term potential for a transformative impact on our understanding of the earth's climate system.

Large margin gaussian mixture models for discriminative training in language recognition  

Science Journals Connector (OSTI)

In this paper we try to integrate the concept of large margin gaussian mixture models (large margin GMMs) into discriminative training for language recognition. We proposed a new language recognition system (SVM-LM-ModelPushing system) which combines model pushing by large margin GMMs (LM-ModelPushing) with original model pushing by SVM (ModelPushing). Our experiments show that LM-ModelPushing includes the language dependent information. What's more our experiments show that LM-ModelPushing contains different language dependent information comparing to ModelPushing. Experiment results on 2007 National Institute of Standards and Technology (NIST) language Recognition Evaluation (LRE) databases show SVM-LM-ModelPushing system gains relative improvement in EER of 9.1% and in minDCF of 8.8% comparing to original ModelPushing system in 30-second tasks.

Spatially Resolved Mapping of Disorder Type and Distribution in Random Systems using Artificial Neural Network Recognition  

SciTech Connect (OSTI)

The spatial variability of the polarization dynamics in thin film ferroelectric capacitors was probed by recognition analysis of spatially-resolved spectroscopic data. Switching spectroscopy piezoresponse force microscopy was used to measure local hysteresis loops and map them on a 2D random-bond, random-field Ising model. A neural-network based recognition approach was utilized to analyze the hysteresis loops and their spatial variability. Strong variability is observed in the polarization dynamics around macroscopic cracks due to the modified local elastic and electric boundary conditions, with most pronounced effect on the length scale of ~100 nm away from the crack.

Kinetics of actinide complexation reactions  

SciTech Connect (OSTI)

Though the literature records extensive compilations of the thermodynamics of actinide complexation reactions, the kinetics of complex formation and dissociation reactions of actinide ions in aqueous solutions have not been extensively investigated. In light of the central role played by such reactions in actinide process and environmental chemistry, this situation is somewhat surprising. The authors report herein a summary of what is known about actinide complexation kinetics. The systems include actinide ions in the four principal oxidation states (III, IV, V, and VI) and complex formation and dissociation rates with both simple and complex ligands. Most of the work reported was conducted in acidic media, but a few address reactions in neutral and alkaline solutions. Complex formation reactions tend in general to be rapid, accessible only to rapid-scan and equilibrium perturbation techniques. Complex dissociation reactions exhibit a wider range of rates and are generally more accessible using standard analytical methods. Literature results are described and correlated with the known properties of the individual ions.

Actinide cation-cation complexes  

SciTech Connect (OSTI)

The +5 oxidation state of U, Np, Pu, and Am is a linear dioxo cation (AnO{sub 2}{sup +}) with a formal charge of +1. These cations form complexes with a variety of other cations, including actinide cations. Other oxidation states of actinides do not form these cation-cation complexes with any cation other than AnO{sub 2}{sup +}; therefore, cation-cation complexes indicate something unique about AnO{sub 2}{sup +} cations compared to actinide cations in general. The first cation-cation complex, NpO{sub 2}{sup +}{center_dot}UO{sub 2}{sup 2+}, was reported by Sullivan, Hindman, and Zielen in 1961. Of the four actinides that form AnO{sub 2}{sup +} species, the cation-cation complexes of NpO{sub 2}{sup +} have been studied most extensively while the other actinides have not. The only PuO{sub 2}{sup +} cation-cation complexes that have been studied are with Fe{sup 3+} and Cr{sup 3+} and neither one has had its equilibrium constant measured. Actinides have small molar absorptivities and cation-cation complexes have small equilibrium constants; therefore, to overcome these obstacles a sensitive technique is required. Spectroscopic techniques are used most often to study cation-cation complexes. Laser-Induced Photacoustic Spectroscopy equilibrium constants for the complexes NpO{sub 2}{sup +}{center_dot}UO{sub 2}{sup 2+}, NpO{sub 2}{sup +}{center_dot}Th{sup 4+}, PuO{sub 2}{sup +}{center_dot}UO{sub 2}{sup 2+}, and PuO{sub 2}{sup +}{center_dot}Th{sup 4+} at an ionic strength of 6 M using LIPAS are 2.4 {plus_minus} 0.2, 1.8 {plus_minus} 0.9, 2.2 {plus_minus} 1.5, and {approx}0.8 M{sup {minus}1}.

Renormalization flows in complex networks  

Science Journals Connector (OSTI)

Complex networks have acquired a great popularity in recent years, since the graph representation of many natural, social, and technological systems is often very helpful to characterize and model their phenomenology. Additionally, the mathematical tools of statistical physics have proven to be particularly suitable for studying and understanding complex networks. Nevertheless, an important obstacle to this theoretical approach is still represented by the difficulties to draw parallelisms between network science and more traditional aspects of statistical physics. In this paper, we explore the relation between complex networks and a well known topic of statistical physics: renormalization. A general method to analyze renormalization flows of complex networks is introduced. The method can be applied to study any suitable renormalization transformation. Finite-size scaling can be performed on computer-generated networks in order to classify them in universality classes. We also present applications of the method on real networks.

Substrate Recognition Strategy for Botulinum Neurotoxin Serotype A

Mark A. Breidenbach1 and Axel T. Brunger2 Mark A. Breidenbach1 and Axel T. Brunger2 1Department of Molecular and Cellular Physiology and 2Howard Hughes Medical Institute and Departments of Molecular and Cellular Physiology, Neurology and Neurological Sciences and Stanford Synchrotron Radiation Laboratory, Stanford University, Stanford, California 94305, USA Clostridal neurotoxins (CNTs) are the causative agents of the neuroparalytic diseases botulism and tetanus1,2 CNTs impair neuronal exocytosis (a process by which neurotransmitter is released into a synapse) through specific proteolysis of essential proteins called SNAREs (soluble N-ethylmaleimide-sensitive factor attachment protein receptors)3. SNARE assembly into a low-energy ternary complex is believed to catalyse membrane fusion, precipitating neurotransmitter release; this process is attenuated in response to SNARE proteolysis4-7. Site-specific SNARE hydrolysis is catalysed by the CNT light chains, a unique group of zinc-dependent endopeptidases (enzymes that catalyse hydrolysis of peptide bonds within other proteins)3. The means by which a CNT properly identifies and cleaves its target SNARE has been a subject of much speculation; it is thought to use one or more regions of enzyme-substrate interaction remote from the active site (exosites)8-10. Using x-ray diffraction data collected in part at SSRL beamline 9-2, we have determined the first structure of a CNT endopeptidase in complex with its target SNARE at a resolution of 2.1 Å: botulinum neurotoxin serotype A (BoNT/A) protease bound to human SNAP-25. The structure, together with enzyme kinetic data, reveals an array of exosites that determine substrate specificity (figure 1).

Restricted Complexity Framework for Nonlinear Adaptive Control in Complex Systems  

SciTech Connect (OSTI)

Control law adaptation that includes implicit or explicit adaptive state estimation, can be a fundamental underpinning for the success of intelligent control in complex systems, particularly during subsystem failures, where vital system states and parameters can be impractical or impossible to measure directly. A practical algorithm is proposed for adaptive state filtering and control in nonlinear dynamic systems when the state equations are unknown or are too complex to model analytically. The state equations and inverse plant model are approximated by using neural networks. A framework for a neural network based nonlinear dynamic inversion control law is proposed, as an extrapolation of prior developed restricted complexity methodology used to formulate the adaptive state filter. Examples of adaptive filter performance are presented for an SSME simulation with high pressure turbine failure to support extrapolations to adaptive control problems.

Recognition and Specificity Determinants of the Human Cbx Chromodomains  

SciTech Connect (OSTI)

The eight mammalian Cbx proteins are chromodomain-containing proteins involved in regulation of heterochromatin, gene expression, and developmental programs. They are evolutionarily related to the Drosophila HP1 (dHP1) and Pc (dPc) proteins that are key components of chromatin-associated complexes capable of recognizing repressive marks such as trimethylated Lys-9 and Lys-27, respectively, on histone H3. However, the binding specificity and function of the human homologs, Cbx1-8, remain unclear. To this end we employed structural, biophysical, and mutagenic approaches to characterize the molecular determinants of sequence contextual methyllysine binding to human Cbx1-8 proteins. Although all three human HP1 homologs (Cbx1, -3, -5) replicate the structural and binding features of their dHP counterparts, the five Pc homologs (Cbx2, -4, -6, -7, -8) bind with lower affinity to H3K9me3 or H3K27me3 peptides and are unable to distinguish between these two marks. Additionally, peptide permutation arrays revealed a greater sequence tolerance within the Pc family and suggest alternative nonhistone sequences as potential binding targets for this class of chromodomains. Our structures explain the divergence of peptide binding selectivity in the Pc subfamily and highlight previously unrecognized features of the chromodomain that influence binding and specificity.

Combing rough set and RBF neural network for large-scale ship recognition in optical satellite images  

Science Journals Connector (OSTI)

Large scale ship recognition in optical remote sensing images is of great importance for many military applications. It aims to recognize the category information of the detected ships for effective maritime surveillance. The contributions of the paper can be summarized as follows: Firstly, based on the rough set theory, the common discernibility degree is used to compute the significance weight of each candidate feature and select valid recognition features automatically; Secondly, RBF neural network is constructed based on the selected recognition features. Experiments on recorded optical satellite images show the proposed method is effective and can get better classification rates at a higher speed than the state of the art methods.

A new GA optimised Reliability Ratio based integration weight estimation scheme for decision fusion Audio-Visual Speech Recognition  

Science Journals Connector (OSTI)

Audio-Visual Speech Recognition (AVSR) using acoustic and visual signals of speech have received attention recently because of its robustness in noisy environments. An important issue in decision fusion AVSR systems is the determination of appropriate integration weight for better performance. A new Genetic Algorithm (GA) based scheme to obtain an appropriate integration weight is proposed here. The performance of the proposed scheme is demonstrated for commonly used mobile functions isolated word recognition via multi-speaker database experiment. The results show that the proposed scheme improves robust recognition accuracy over conventional unimodal systems and other related bimodal systems, namely, Reliability ratio and Neural Network based AVSR systems.

Epidemic processes in complex networks  

E-Print Network [OSTI]

In recent years the research community has accumulated overwhelming evidence for the emergence of complex and heterogeneous connectivity patterns in a wide range of biological and socio-technical systems. The complex properties of real world networks have a profound impact on the behavior of equilibrium and non-equilibrium phenomena occurring in various systems, and the study of epidemic spreading is central to our understanding of the unfolding of dynamical processes in complex networks. The theoretical analysis of epidemic spreading in heterogeneous networks requires the development of novel analytical frameworks, and it has produced results of conceptual and practical relevance. Here we present a coherent and comprehensive review of the vast research activity concerning epidemic processes, detailing the successful theoretical approaches as well as making their limits and assumptions clear. Physicists, epidemiologists, computer and social scientists share a common interest in studying epidemic spreading and...

Information entropy of complex structures  

Science Journals Connector (OSTI)

The information entropy function provides a sensitive measure of the complexity of a multi-component material system, where complexity refers to the range of length scales over which morphological features are present. This is demonstrated for an evolving, two-phase microstructure simulated by a population of interacting particles on a two-dimensional surface. The information entropy increases at all length scales as the initially random configuration of particles evolves to produce a distribution of ramified clusters. Maxima in the normalized information entropy function, which is obtained by subtracting the information entropy of a perfectly random configuration from that of the clustered configuration, occur at length scales for which the system most differs from a random configuration, while minima occur at length scales for which the system is periodic or relatively ordered. Besides analysis of complex microstructures, information entropy is useful in detecting features present in any collection of data.

Structures of GRP94-Nucleotide Complexes Reveal Mechanistic Differences  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Structures of GRP94-Nucleotide Structures of GRP94-Nucleotide Complexes Reveal Mechanistic Differences between the Hsp90 Chaperones Life depends on the biochemical activity of the thousands of proteins that inhabit and decorate the surface of every one of our cells. Proteins themselves, although simple linear combinations of the twenty amino acids, derive their remarkable properties from the complex three-dimensional structures into which they fold. In this way, enzyme active sites are created, protein-protein recognition surfaces are formed, and the chemistry of life is set in motion. Although in principle the precise three-dimensional structure for each protein is encoded in its linear chain of amino acids, in practice it is often difficult or impossible for a protein to achieve this final fold on its own in the context of a cellular environment that is packed to the gills with millions of other proteins, nucleic acids, carbohydrates, lipids, and other small molecules. As a result, cells have evolved a corps of proteins known as molecular chaperones that assist newly synthesized proteins as they adopt their active fold. One such family of chaperones is known as the hsp90 family (Pratt and Toft, 2003). "Client" proteins of the hsp90 family are diverse, and their functions range from signal transduction to immune response. Specific inhibitors of hsp90 chaperones exhibit potent anti-tumor activity (Chiosis et al., 2006; Sharp and Workman, 2006), showing that preventing the proper folding of client proteins, many of which are implicated in cancer, can have profound therapeutic implications.

Invisible defects in complex crystals  

E-Print Network [OSTI]

We show that invisible localized defects, i.e. defects that can not be detected by an outside observer, can be realized in a crystal with an engineered imaginary potential at the defect site. The invisible defects are synthesized by means of supersymmetric (Darboux) transformations of an ordinary crystal using band-edge wave functions to construct the superpotential. The complex crystal has an entire real-valued energy spectrum and Bragg scattering is not influenced by the defects. An example of complex crystal synthesis is presented for the Mathieu potential.

Ion Recognition Approach to Volume Reduction of Alkaline Tank Waste by Separation and Recycle of Sodium Hydroxide and Sodium Nitrate  

SciTech Connect (OSTI)

Disposal of high-level nuclear waste is horrendously expensive, in large part because the actual radioactive matter in the tanks has been diluted over 1000-fold by ordinary inorganic chemicals. Treatment processes themselves can exacerbate the problem by adding further volume to the waste. Waste retrieval and sludge washing, for example, will require copious amounts of sodium hydroxide. If the needed sodium hydroxide could be separated from the waste and recycled, however, the addition of fresh sodium hydroxide could be avoided, ultimately reducing the final waste volume and associated disposal costs. The major objective of this research is to explore new liquid-liquid extraction approaches to the selective separation of sodium hydroxide from alkaline high-level wastes stored in underground tanks at the Hanford and Savannah River sites. Consideration is also given to separating potassium and abundant anions, including nitrate, nitrite, aluminate, and carbonate. Salts of these ions represent possible additional value for recycle, alternative disposal, or even use as commodity chemicals. A comprehensive approach toward understanding the extractive chemistry of these salts is envisioned, involving systems of varying complexity, from use of simple solvents to new bifunctional host molecules for ion-pair recognition. These extractants will ideally require no adjustment of the waste composition and will release the extracted salt into water, thereby consuming no additional chemicals and producing no additional waste volume. The overall goal of this research is to provide a scientific foundation upon which the feasibility of new liquid-liquid extraction chemistry applicable to the bulk reduction of the volume of tank waste can be evaluated.

Ion Recognition Approach to Volume Reduction of Alkaline Tank Waste by Separation and Recycle of Sodium Hydroxide and Sodium Nitrate  

SciTech Connect (OSTI)

The objective of this research is to explore new liquid-liquid extraction approaches to the selective separation of major sodium salts from alkaline high-level wastes stored in underground tanks at Hanford, Savannah River, and Oak Ridge sites. Disposal of high level waste is horrendously expensive, in large part because the actual radioactive matter in the tanks has been diluted over 1000-fold by ordinary inorganic chemicals. Since the residual bulk chemicals must still undergo expensive treatment and disposal after most of the hazardous radionuclides have been removed, large cost savings will result from processes that reduce the overall waste volume. It is proposed that major cost savings can be expected if sodium hydroxide needed for sludge washing can be obtained from the waste itself, thus avoiding the addition of yet another bulk chemical to the waste and still further increase of the waste volume and disposal cost. Secondary priority is given to separating potassium an d abundant anions, including nitrate, nitrite, aluminate, and carbonate. Salts of these ions represent possible additional value for recycle, alternative disposal, or even use as commodity chemicals. A comprehensive approach toward understanding the extractive chemistry of these salts is envisioned, involving systems of varying complexity, from use of simple solvents to new bifunctional host molecules for ion-pair recognition.

Platinum complexes containing phosphino amino acid and amino acid ester ligands, built upon the PPhNR2 platform, have been synthesized and characterized (PPhNR2= [1,3-diaza]-5-phenyl phosphacyclohexane, R=glycine or glycine ester). These complexes were characterized by 31P, 13C, 1H, 195Pt NMR spectroscopy and mass spectrometry. The X-ray crystal structure of one of the complexes, [PtCl2(PPhNGlyester 2)2], is also reported. These biologically inspired ligands have potential use in homogeneous catalysis, with special applications in chiral chemistry and water soluble chemistry. These complexes also provide a foundation upon which larger peptides can be attached, to allow the introduction of enzyme-like features onto small molecule catalysts.

Hybrid optical/digital architecture for distortion-invariant pattern recognition. Master's thesis  

SciTech Connect (OSTI)

This research investigated optical techniques for pattern recognition. An optical joint transform correlator was implemented using a magneto-optic spatial light modulator, and a charge coupled device (CCD) camera and frame grabber under personal computer (PC) control. A hybrid optical/digital architecture that could potentially perform position, scale, and rotation invariant pattern recognition using a computer generated hologram (CGH) was also implemented. The joint transform correlator was tested using forward looking infrared (FLIR) imagery containing tactical targets, and gave very good results. New techniques for binarizing the FLIR inputs and the fringe pattern of the joint transform were discovered. The input binarization used both scene average and a localized energy normalization technique for binarization. This resulted in reduced scene background, while retaining target detail. The fringe binarization technique subtracted the Fourier transform of the scene from the joint transform, and binarized on the average difference. This new technique was a significant improvement over recent published designs.

The contribution of pattern recognition of seismic and morphostructural data to seismic hazard assessment  

E-Print Network [OSTI]

The reliable statistical characterization of the spatial and temporal properties of large earthquakes occurrence is one of the most debated issues in seismic hazard assessment, due to the unavoidably limited observations from past events. We show that pattern recognition techniques, which are designed in a formal and testable way, may provide significant space-time constraints about impending strong earthquakes. This information, when combined with physically sound methods for ground shaking computation, like the neo-deterministic approach (NDSHA), may produce effectively preventive seismic hazard maps. Pattern recognition analysis of morphostructural data provide quantitative and systematic criteria for identifying the areas prone to the largest events, taking into account a wide set of possible geophysical and geological data, whilst the formal identification of precursory seismicity patterns (by means of CN and M8S algorithms), duly validated by prospective testing, provides useful constraints about impend...

An investigation on visual and audiovisual stimulus based emotion recognition using EEG  

Science Journals Connector (OSTI)

In this paper, we investigate the possibility of using visual and audio visual stimulus for detecting the human emotion by measuring electroencephalogram (EEG). Visual and audiovisual stimulus based protocols is designed to acquire the EEG signals over five healthy subjects using 63 biosensors. We propose the analysis of EEG signals using discrete wavelet transform and classification using neural network. EEG signals were decomposed into five frequency sub-bands using 'db4' wavelet function and two statistical features were extracted from the alpha band. These statistical features were used as input to the neural network for classifying five emotions (disgust, happy, surprise, sad and anger). In the experiments of recognising human emotions from visual and audiovisual stimulus, the average recognition rate of 56.66% and 66.67% is obtained. The experimental result shows that the audiovisual stimulus based emotion recognition gives better classification accuracy over visual stimulus.

1: Redox chemistry of bimetallic fulvalene complexes; 2: Oligocyclopentadienyl complexes  

SciTech Connect (OSTI)

The electrochemistry of the heterobimetallic complexes (fulvalene)WFe(CO){sub 5} (30) and (fulvalene)WRu(CO){sub 5} (31) has been investigated. Compound 30 is reduced in two one-electron processes, and this behavior was exploited synthetically to prepare a tetranuclear dimer by selective metal reduction. Complex 31 displayed a distinction between the metals upon reoxidation of the dianion, allowing the formation of a dimer by selective metal anion oxidation. The redox behavior of 30 led to an investigation of the use of electrocatalysis to effect metal-specific ligand substitution. It was found that reduction of 30 with a catalytic amount of CpFe(C{sub 6}Me{sub 6}) (97) in the presence of excess P(OMe){sub 3} or PMe{sub 3} led to the formation of the zwitterions (fulvalene)[W(CO){sub 3}{sup {minus}}][Fe(CO)PR{sub 3}{sup +}] (107, R = P(OMe){sub 3}; 108, R = PMe{sub 3}). Compound 31 also displayed unique behavior with different reducing agents, as the monosubstituted zwitterion (fulvalene)[W(CO){sub 3}{sup {minus}}][Ru(CO){sub 2}(PMe{sub 3}){sup +}] was obtained when 97 was used while the disubstituted complex (fulvalene) [W(CO){sub 3}{sup {minus}}] [Ru(CO)(PMe{sub 3}){sub 2}{sup +}] was produced when Cp*Fe(C{sub 6}Me{sub 6}) was the catalyst. Potential synthetic routes to quatercyclopentadienyl complexes were also explored. Various attempts to couple heterobimetallic fulvalene compounds proved to be unsuccessful. 138 refs.

Functional Proteomic And Structural Insights Into Molecular Recognition in the Nitrilase Family Enzymes  

SciTech Connect (OSTI)

Nitrilases are a large and diverse family of nonpeptidic C-N hydrolases. The mammalian genome encodes eight nitrilase enzymes, several of which remain poorly characterized. Prominent among these are nitrilase-1 (Nit1) and nitrilase-2 (Nit2), which, despite having been shown to exert effects on cell growth and possibly serving as tumor suppressor genes, are without known substrates or selective inhibitors. In previous studies, we identified several nitrilases, including Nit1 and Nit2, as targets for dipeptide-chloroacetamide activity-based proteomics probes. Here, we have used these probes, in combination with high-resolution crystallography and molecular modeling, to systematically map the active site of Nit2 and identify residues involved in molecular recognition. We report the 1.4 {angstrom} crystal structure of mouse Nit2 and use this structure to identify residues that discriminate probe labeling between the Nit1 and Nit2 enzymes. Interestingly, some of these residues are conserved across all vertebrate Nit2 enzymes and, conversely, not found in any vertebrate Nit1 enzymes, suggesting that they are key discriminators of molecular recognition between these otherwise highly homologous enzymes. Our findings thus point to a limited set of active site residues that establish distinct patterns of molecular recognition among nitrilases and provide chemical probes to selectively perturb the function of these enzymes in biological systems.

ASSP p. 579 (1977)] the Votrax VS6 and ML1 systems (all phoneme synthesizers) and the institute's MISS system (linear predictive compression of recorded speech) [Sanders and Laddaga J. Acoust. Soc. Am. 60 Suppl. 1 S76(A) (1976)]. Human speech was used as a control. A sign test was used to rank the systems; in both experiments the ordering was human speech MISS Allen/Klatt Votrax. The pairwise comparisons were significant at less than the 1% level except for three cases involving the control MISS and Allen/Klatt. A learning study was done for the letter experiment using linear probability models whose results corroborated the ranking determined from the sign test. Study was made of individual problem sounds for each system in terms of human vocal parameters. [Supported by NSF grant SED74?15016?A02.

Fusion under a complex barrier  

Science Journals Connector (OSTI)

The mechanism of fusion of two heavy nuclei is formulated within the concept of transmission across a mildly absorptive effective fusion barrier (EFB). The intensity of transmitted waves across such a barrier could be represented by the product TRPS where TR stands for the transmission coefficient across the corresponding real barrier and PS is a factor of survival probability against absorption under the complex barrier. The justification of this result and the physical basis of the above EFB transmission model of fusion, which is complementary to the definition of fusion based on absorption in the interior region known as the direct reaction model (DRM), are demonstrated in the case of a complex square well potential with a complex rectangular barrier. Based on a WKB approach, expressions for TR for different partial waves utilizing a realistic nucleus-nucleus potential are derived. Using the resulting expressions for the fusion cross section (?F), the experimental values of ?F and the corresponding data of the average angular momentum of the fused body are explained satisfactorily over a wide range of energy around the Coulomb barrier in various heavy ion systems such as 16O+152,154Sm, 58,64Ni+58,64Ni, 64Ni+92Zr, and 64Ni+100Mo.

Developement of 3D Vertically Integrated Pattern Recognition Associative Memory (VIPRAM)  

SciTech Connect (OSTI)

Many next-generation physics experiments will be characterized by the collection of large quantities of data, taken in rapid succession, from which scientists will have to unravel the underlying physical processes. In most cases, large backgrounds will overwhelm the physics signal. Since the quantity of data that can be stored for later analysis is limited, real-time event selection is imperative to retain the interesting events while rejecting the background. Scaling of current technologies is unlikely to satisfy the scientific needs of future projects, so investments in transformational new technologies need to be made. For example, future particle physics experiments looking for rare processes will have to address the demanding challenges of fast pattern recognition in triggering as detector hit density becomes significantly higher due to the high luminosity required to produce the rare processes. In this proposal, we intend to develop hardware-based technology that significantly advances the state-of-the-art for fast pattern recognition within and outside HEP using the 3D vertical integration technology that has emerged recently in industry. The ultimate physics reach of the LHC experiments will crucially depend on the tracking trigger's ability to help discriminate between interesting rare events and the background. Hardware-based pattern recognition for fast triggering on particle tracks has been successfully used in high-energy physics experiments for some time. The CDF Silicon Vertex Trigger (SVT) at the Fermilab Tevatron is an excellent example. The method used there, developed in the 1990's, is based on algorithms that use a massively parallel associative memory architecture to identify patterns efficiently at high speed. However, due to much higher occupancy and event rates at the LHC, and the fact that the LHC detectors have a much larger number of channels in their tracking detectors, there is an enormous challenge in implementing pattern recognition for a track trigger, requiring about three orders of magnitude more associative memory patterns than what was used in the original CDF SVT. Significant improvement in the architecture of associative memory structures is needed to run fast pattern recognition algorithms of this scale. We are proposing the development of 3D integrated circuit technology as a way to implement new associative memory structures for fast pattern recognition applications. Adding a 'third' dimension to the signal processing chain, as compared to the two-dimensional nature of printed circuit boards, Field Programmable Gate Arrays (FPGAs), etc., opens up the possibility for new architectures that could dramatically enhance pattern recognition capability. We are currently performing preliminary design work to demonstrate the feasibility of this approach. In this proposal, we seek to develop the design and perform the ASIC engineering necessary to realize a prototype device. While our focus here is on the Energy Frontier (e.g. the LHC), the approach may have applications in experiments in the Intensity Frontier and the Cosmic Frontier as well as other scientific and medical projects. In fact, the technique that we are proposing is very generic and could have wide applications far beyond track trigger, both within and outside HEP.

Well defined time frames and feature vectors describing the speech, to the degree required, can be formed. Such feature vectors can uniquely characterize the speech unit being articulated each time frame. The onset of speech, rejection of external noise, vocalized pitch periods, articulator conditions, accurate timing, the identification of the speaker, acoustic speech unit recognition, and organ mechanical parameters can be determined.

Fast recognition of single molecules based on single-event photon statistics  

SciTech Connect (OSTI)

Mandel's Q parameter, which is determined from single-event photon statistics, provides an alternative way to recognize single molecules with fluorescence detection, other than the second-order correlation function. It is shown that the Q parameter of an assumed ideal double-molecule fluorescence with the same average photon number as that of the sample fluorescence can act as the criterion for single-molecule recognition. The influence of signal-to-background ratio and the error estimates for photon statistics are also presented. We have applied this method to ascertain single Cy5 dye molecules within hundreds of milliseconds.

Structural basis for dsRNA recognition and interferon antagonism by Ebola VP35  

SciTech Connect (OSTI)

Ebola viral protein 35 (VP35), encoded by the highly pathogenic Ebola virus, facilitates host immune evasion by antagonizing antiviral signaling pathways, including those initiated by RIG-I-like receptors. Here we report the crystal structure of the Ebola VP35 interferon inhibitory domain (IID) bound to short double-stranded RNA (dsRNA), which together with in vivo results reveals how VP35-dsRNA interactions contribute to immune evasion. Conserved basic residues in VP35 IID recognize the dsRNA backbone, whereas the dsRNA blunt ends are 'end-capped' by a pocket of hydrophobic residues that mimic RIG-I-like receptor recognition of blunt-end dsRNA. Residues critical for RNA binding are also important for interferon inhibition in vivo but not for viral polymerase cofactor function of VP35. These results suggest that simultaneous recognition of dsRNA backbone and blunt ends provides a mechanism by which Ebola VP35 antagonizes host dsRNA sensors and immune responses.

Structural basis for leucine-rich nuclear export signal recognition by CRM1  

SciTech Connect (OSTI)

CRM1 (also known as XPO1 and exportin 1) mediates nuclear export of hundreds of proteins through the recognition of the leucine-rich nuclear export signal (LR-NES). Here we present the 2.9 {angstrom} structure of CRM1 bound to snurportin 1 (SNUPN). Snurportin 1 binds CRM1 in a bipartite manner by means of an amino-terminal LR-NES and its nucleotide-binding domain. The LR-NES is a combined {alpha}-helical-extended structure that occupies a hydrophobic groove between two CRM1 outer helices. The LR-NES interface explains the consensus hydrophobic pattern, preference for intervening electronegative residues and inhibition by leptomycin B. The second nuclear export signal epitope is a basic surface on the snurportin 1 nucleotide-binding domain, which binds an acidic patch on CRM1 adjacent to the LR-NES site. Multipartite recognition of individually weak nuclear export signal epitopes may be common to CRM1 substrates, enhancing CRM1 binding beyond the generally low affinity LR-NES. Similar energetic construction is also used in multipartite nuclear localization signals to provide broad substrate specificity and rapid evolution in nuclear transport.

Physical mapping of complex genomes  

DOE Patents [OSTI]

Method for simultaneous identification of overlapping cosmid clones among multiple cosmid clones and the use of the method for mapping complex genomes are provided. A library of cosmid clones that contains the DNA to be mapped is constructed and arranged in a manner such that individual clones can be identified and replicas of the arranged clones prepared. In preferred embodiments, the clones are arranged in a two dimensional matrix. In such embodiments, the cosmid clones in a row are pooled, mixed probes complementary to the ends of the DNA inserts int he pooled clones are synthesized, hybridized to a first replica of the library. Hybridizing clones, which include the pooled row, are identified. A second portion of clones is prepared by pooling cosmid clones that correspond to a column in the matrix. The second pool thereby includes one clone from the first portion pooled clones. This common clone is located on the replica at the intersection of the column and row. Mixed probes complementary to the ends of the DNA inserts in the second pooled portion of clones are prepared and hybridized to a second replica of the library. The hybridization pattern on the first and second replicas of the library are compared and cross-hybridizing clones, other than the clones in the pooled column and row, that hybridize to identical clones in the first and second replicas are identified. These clones necessarily include DNA inserts that overlap with the DNA insert int he common clone located at the intersection of the pooled row and pooled column. The DNA in the entire library may be mapped by pooling the clones in each of the rows and columns of the matrix, preparing mixed end-specific probes and hybridizing the probes from each row or column to a replica of the library. Since all clones in the library are located at the intersection of a column and a row, the overlapping clones for all clones in the library may be identified and a physical map constructed. In other preferred embodiments, the cosmid clones are arranged in a three dimensional matrix, pooled and compared in threes according to intersecting planes of the three dimensional matrix. Arrangements corresponding to geometries of higher dimensions may also be prepared and used to simultaneously identify overlapping clones in highly complex libraries with relatively few hybridization reactions.

Demonstration of a Multistep Mechanism for Assembly of the SRPSRP Receptor Complex: Implications for the Catalytic Role of SRP RNA  

Science Journals Connector (OSTI)

Two \\{GTPases\\} in the signal recognition particle (SRP) and its receptor (SR) control the delivery of newly synthesized proteins to the endoplasmic reticulum or plasma membrane. During the protein targeting reaction, the 4.5S SRP RNA accelerates the association between the two \\{GTPases\\} by 400-fold. Using fluorescence resonance energy transfer, we demonstrate here that formation of a stable SRPSR complex involves two distinct steps: a fast initial association between SRP and SR to form a GTP-independent early complex and then a GTP-dependent conformational rearrangement to form the stable final complex. We also found that the 4.5S SRP RNA significantly stabilizes the early GTP-independent intermediate. Furthermore, mutational analyses show that there is a strong correlation between the ability of the mutant SRP \\{RNAs\\} to stabilize the early intermediate and their ability to accelerate SRPSR complex formation. We propose that the SRP RNA, by stabilizing the early intermediate, can give this transient intermediate a longer life time and therefore a higher probability to rearrange to the stable final complex. This provides a coherent model that explains how the 4.5S RNA exerts its catalytic role in SRPSR complex assembly.

Structure of a GDP:AlF4 Complex of the SRP \\{GTPases\\} Ffh and FtsY, and Identification of a Peripheral Nucleotide Interaction Site  

Science Journals Connector (OSTI)

The signal recognition particle (SRP) \\{GTPases\\} Ffh and FtsY play a central role in co-translational targeting of proteins, assembling in a GTP-dependent manner to generate the SRP targeting complex at the membrane. A suite of residues in FtsY have been identified that are essential for the hydrolysis of GTP that accompanies disengagement. We have argued previously on structural grounds that this region mediates interactions that serve to activate the complex for disengagement and term it the activation region. We report here the structure of a complex of the SRP \\{GTPases\\} formed in the presence of GDP:AlF4. This complex accommodates the putative transition-state analog without undergoing significant change from the structure of the ground-state complex formed in the presence of the GTP analog GMPPCP. However, small shifts that do occur within the shared catalytic chamber may be functionally important. Remarkably, an external nucleotide interaction site was identified at the activation region, revealed by an unexpected contaminating GMP molecule bound adjacent to the catalytic chamber. This site exhibits conserved sequence and structural features that suggest a direct interaction with RNA plays a role in regulating the activity of the SRP targeting complex.

We report that the IL-7R{alpha} ectodomain uses glycosylation to modulate its binding constants to IL-7, unlike the other receptors in the {gamma}{sub c} family. IL-7 binds glycosylated IL-7R{alpha} 300-fold more tightly than unglycosylated IL-7R{alpha}, and the enhanced affinity is attributed primarily to an accelerated on rate. Structural comparison of IL-7 in complex to both forms of IL-7R{alpha} reveals that glycosylation does not participate directly in the binding interface. The SCID mutations of IL-7R{alpha} locate outside the binding interface with IL-7, suggesting that the expressed mutations cause protein folding defects in IL-7R{alpha}. The IL-7/IL-7R{alpha} structures provide a window into the molecular recognition events of the IL-7 signaling cascade and provide sites to target for designing new therapeutics to treat IL-7-related diseases.

Spreading dynamics in complex networks  

Science Journals Connector (OSTI)

Searching for influential spreaders in complex networks is an issue of great significance for applications across various domains, ranging from epidemic control, innovation diffusion, viral marketing, and social movement to idea propagation. In this paper, we first display some of the most important theoretical models that describe spreading processes, and then discuss the problem of locating both the individual and multiple influential spreaders respectively. Recent approaches in these two topics are presented. For the identification of privileged single spreaders, we summarize several widely used centralities, such as degree, betweenness centrality, PageRank, k-shell, etc. We investigate the empirical diffusion data in a large scale online social communityLiveJournal. With this extensive dataset, we find that various measures can convey very distinct information of nodes. Of all the users in the LiveJournal social network, only a small fraction of them are involved in spreading. For the spreading processes in LiveJournal, while degree can locate nodes participating in information diffusion with higher probability, k-shell is more effective in finding nodes with a large influence. Our results should provide useful information for designing efficient spreading strategies in reality.

Information mobility in complex networks  

Science Journals Connector (OSTI)

The concept of information mobility in complex networks is introduced on the basis of a stochastic process taking place in the network. The transition matrix for this process represents the probability that the information arising at a given node is transferred to a target one. We use the fractional powers of this transition matrix to investigate the stochastic process at fractional time intervals. The mobility coefficient is then introduced on the basis of the trace of these fractional powers of the stochastic matrix. The fractional time at which a network diffuses 50% of the information contained in its nodes (1/k50) is also introduced. We then show that the scale-free random networks display a better spread of information than the non-scale-free ones. We study 38 real-world networks and analyze their performance in spreading information from their nodes. We find that some real-world networks perform even better than the scale-free networks with the same average degree and we point out some of the structural parameters that make this possible.

Advanced nuclear plant control complex  

DOE Patents [OSTI]

An advanced control room complex for a nuclear power plant, including a discrete indicator and alarm system (72) which is nuclear qualified for rapid response to changes in plant parameters and a component control system (64) which together provide a discrete monitoring and control capability at a panel (14-22, 26, 28) in the control room (10). A separate data processing system (70), which need not be nuclear qualified, provides integrated and overview information to the control room and to each panel, through CRTs (84) and a large, overhead integrated process status overview board (24). The discrete indicator and alarm system (72) and the data processing system (70) receive inputs from common plant sensors and validate the sensor outputs to arrive at a representative value of the parameter for use by the operator during both normal and accident conditions, thereby avoiding the need for him to assimilate data from each sensor individually. The integrated process status board (24) is at the apex of an information hierarchy that extends through four levels and provides access at each panel to the full display hierarchy. The control room panels are preferably of a modular construction, permitting the definition of inputs and outputs, the man machine interface, and the plant specific algorithms, to proceed in parallel with the fabrication of the panels, the installation of the equipment and the generic testing thereof.

CORRELATION PROFILES AND MOTIFS IN COMPLEX NETWORKS.  

SciTech Connect (OSTI)

Networks have recently emerged as a unifying theme in complex systems research [1]. It is in fact no coincidence that networks and complexity are so heavily intertwined. Any future definition of a complex system should reflect the fact that such systems consist of many mutually interacting components. These components are far from being identical as say electrons in systems studied by condensed matter physics. In a truly complex system each of them has a unique identity allowing one to separate it from the others. The very first question one may ask about such a system is which other components a given component interacts with? This information system wide can be visualized as a graph, whose nodes correspond to individual components of the complex system in question and edges to their mutual interactions. Such a network can be thought of as a backbone of the complex system. Of course, system's dynamics depends not only on the topology of an underlying network but also on the exact form of interaction of components with each other, which can be very different in various complex systems. However, the underlying network may contain clues about the basic design principles and/or evolutionary history of the complex system in question. The goal of this article is to provide readers with a set of useful tools that would help to decide which features of a complex network are there by pure chance alone, and which of them were possibly designed or evolved to their present state.

A geometric entropy measuring networks complexity  

E-Print Network [OSTI]

A central issue of the science of complex systems is the quantitative characterization of complexity. In the present work a new entropic measure of complexity is proposed which has unprecedented advantages. Starting from the framework of the so-called information geometry we propose a new and constructive way to associate to a - in principle any - network a differentiable object (a Riemannian manifold) whose volume is used to define an entropy. The effectiveness of this new entropic measure of networks complexity is successfully proved through its capability of detecting a classical phase transition in random graphs: the emergence of the "giant component" according to the celebrated Erd\\"os-R\\'enyi theorem.

Models of organometallic complexes for optoelectronic applications  

E-Print Network [OSTI]

Organometallic complexes have potential applications as the optically active components of organic light emitting diodes (OLEDs) and organic photovoltaics (OPV). Development of more effective complexes may be aided by understanding their excited state properties. Here we discuss two key theoretical approaches to investigate these complexes: first principles atomistic models and effective Hamiltonian models. We review applications of these methods, such as, determining the nature of the emitting state, predicting the fraction of injected charges that form triplet excitations, and explaining the sensitivity of device performance to small changes in the molecular structure of the organometallic complexes.

Environmental policy in a complex world  

Science Journals Connector (OSTI)

Most concepts of environmental policy do not consider adequately the complexity of nature and society. While neoclassical economics seems to fall into the trap of steering illusion, evolutionary economic concepts that consider societal complexity are too optimistic about the favours of laissez-faire. A coevolutionary perspective may combine both it may consider the complexity of societal processes as well as environmental constraints. As an example for a coevolutionary strategy, the dematerialisation approach illustrates how environmental policy can handle the two problems of complexity.

Crystallization and preliminary crystallographic analysis of the type IIL restriction enzyme MmeI in complex with DNA  

SciTech Connect (OSTI)

Type IIL restriction enzymes have rejuvenated the search for user-specified DNA binding and cutting. By aligning and contrasting the highly comparable amino-acid sequences yet diverse recognition specificities across the family of enzymes, amino acids involved in DNA binding have been identified and mutated to produce alternative binding specificities. To date, the specificity of MmeI (a type IIL restriction enzyme) has successfully been altered at positions 3, 4 and 6 of the asymmetric TCCRAC (where R is a purine) DNA-recognition sequence. To further understand the structural basis of MmeI DNA-binding specificity, the enzyme has been crystallized in complex with its DNA substrate. The crystal belonged to space group P1, with unit-cell parameters a = 61.73, b = 94.96, c = 161.24 {angstrom}, {alpha} = 72.79, {beta} = 89.12, {gamma} = 71.68{sup o}, and diffracted to 2.6 {angstrom} resolution when exposed to synchrotron radiation. The structure promises to reveal the basis of MmeI DNA-binding specificity and will complement efforts to create enzymes with novel specificities.

Complex networks in confined comminution  

Science Journals Connector (OSTI)

The physical process of confined comminution is investigated within the framework of complex networks. We first characterize the topology of the unweighted contact networks as generated by the confined comminution process. We find this process gives rise to an ultimate contact network which exhibits a scale-free degree distribution and small world properties. In particular, if viewed in the context of networks through which information travels along shortest paths, we find that the global average of the node vulnerability decreases as the comminution process continues, with individual node vulnerability correlating with grain size. A possible application to the design of synthetic networks (e.g., sensor networks) is highlighted. Next we turn our attention to the physics of the granular comminution process and examine force transmission with respect to the weighted contact networks, where each link is weighted by the inverse magnitude of the normal force acting at the associated contact. We find that the strong forces (i.e., force chains) are transmitted along pathways in the network which are mainly following shortest-path routing protocols, as typically found, for example, in communication systems. Motivated by our earlier studies of the building blocks for self-organization in dense granular systems, we also explore the properties of the minimal contact cycles. The distribution of the contact strain energy intensity of 4-cycle motifs in the ultimate state of the confined comminution process is shown to be consistent with a scale-free distribution with infinite variance, thereby suggesting that 4-cycle arrangements of grains are capable of storing vast amounts of energy in their contacts without breaking.

A new tool for protein fold recognition: A Bayesian heuristic threading algorithm.  

SciTech Connect (OSTI)

This paper presents a new threading algorithm, designed to be used in protein fold recognition. Its purpose is to contribute toward the goal of predicting three-dimensional structures of proteins from knowledge of their amino-acid sequences alone. Sequences for new proteins are being discovered at a rapid rate, as a result of the Human Genome Project, and related genome research. Understanding of protein folding, and especially the ability to predict the 3D fold from the sequence, is crucial to the understanding of the function of these new proteins. This is considered by many to be the most important problem in contemporary molecular biology. Numerical tests of the speed and reliability of the algorithm are described, along with comparisons with two popular threading algorithms. For the systems examined, the new method constitutes a significant improvement.

Daily Stress Recognition from Mobile Phone Data, Weather Conditions and Individual Traits  

E-Print Network [OSTI]

Research has proven that stress reduces quality of life and causes many diseases. For this reason, several researchers devised stress detection systems based on physiological parameters. However, these systems require that obtrusive sensors are continuously carried by the user. In our paper, we propose an alternative approach providing evidence that daily stress can be reliably recognized based on behavioral metrics, derived from the user's mobile phone activity and from additional indicators, such as the weather conditions (data pertaining to transitory properties of the environment) and the personality traits (data concerning permanent dispositions of individuals). Our multifactorial statistical model, which is person-independent, obtains the accuracy score of 72.28% for a 2-class daily stress recognition problem. The model is efficient to implement for most of multimedia applications due to highly reduced low-dimensional feature space (32d). Moreover, we identify and discuss the indicators which have stron...

The rhetoric of business and complexity  

Science Journals Connector (OSTI)

Management and organisation research has been too alacritous espousing non-linearity, a.k.a. complexity, and trying to adapt it to its purposes. Complexity has yet to become fully mainstream even in the natural sciences and, at any rate, a prerequisite for business people to become involved in discussions of emerging behaviour, statistical mechanics, chaos theories and the like, is that they first become acquainted with decision science, systems theory, linearity, probability and statistics. In addition, business complexity and colloquial complexity are not always the same (in fact, they seldom are) as non-linear complexity; epistemological issues do not necessarily have practical consequences; and not all theoretical impossibilities do translate into practical impotence.

Physical mapping of complex genomes  

DOE Patents [OSTI]

A method for the simultaneous identification of overlapping cosmid clones among multiple cosmid clones and the use of the method for mapping complex genomes are provided. A library of cosmid clones that contains the DNA to be mapped is constructed and arranged in a manner such that individual clones can be identified and replicas of the arranged clones prepared. In preferred embodiments, the clones are arranged in a two dimensional matrix. In such embodiments, the cosmid clones in a row are pooled, mixed probes complementary to the ends of the DNA inserts in the pooled clones are synthesized, hybridized to a first replica of the library. Hybridizing clones, which include the pooled row, are identified. A second portion of clones is prepared by pooling cosmid clones that correspond to a column in the matrix. The second pool thereby includes one clone from the first portion pooled clones. This common clone is located on the replica at the intersection of the column and row. Mixed probes complementary to the ends of the DNA inserts in the second pooled portion of clones are prepared and hybridized to a second replica of the library. The hybridization pattern on the first and second replicas of the library are compared and cross-hybridizing clones, other than the clones in the pooled column and row, that hybridize to identical clones in the first and second replicas are identified. These clones necessarily include DNA inserts that overlap with the DNA insert in the common clone located at the intersection of the pooled row and pooled column. The DNA in the entire library may be mapped by pooling the clones in each of the rows and columns of the matrix, preparing mixed end-specific probes and hybridizing the probes from each row or column to a replica of the library. Since all clones in the library are located at the intersection of a column and a row, the overlapping clones for all clones in the library may be identified and a physical map constructed.

Structure of the GMPPNP-stabilized NG domain complex of the SRP \\{GTPases\\} Ffh and FtsY  

Science Journals Connector (OSTI)

Ffh and FtsY are \\{GTPase\\} components of the signal recognition particle co-translational targeting complex that assemble during the SRP cycle to form a GTP-dependent and pseudo twofold symmetric heterodimer. Previously the SRP \\{GTPase\\} heterodimer has been stabilized and purified for crystallographic studies using both the non-hydrolysable GTP analog GMPPCP and the pseudo-transition state analog GDP:AlF4, revealing in both cases a buried nucleotide pair that bridges and forms a key element of the heterodimer interface. A complex of Ffh and FtsY from Thermus aquaticus formed in the presence of the analog GMPPNP could not be obtained, however. The origin of this failure was previously unclear, and it was thought to have arisen from either instability of the analog, or, alternatively, from differences in its interactions within the tightly conscribed composite active site chamber of the complex. Using insights gained from the previous structure determinations, we have now determined the structure of the SRP \\{GTPase\\} targeting heterodimer stabilized by the non-hydrolysable GTP analog GMPPNP. The structure demonstrates how the different GTP analogs are accommodated within the active site chamber despite slight differences in the geometry of the phosphate chain. It also reveals a K+ coordination site at the highly conserved DARGG loop at the N/G interdomain interface.

Managing Complex Network Operation with Predictive Analytics  

SciTech Connect (OSTI)

Complex networks play an important role in modern societies. Their failures, such as power grid blackouts, would lead to significant disruption of peoples life, industry and commercial activities, and result in massive economic losses. Operation of these complex networks is an extremely challenging task due to their complex structures, wide geographical coverage, complex data/information technology systems, and highly dynamic and nonlinear behaviors. None of the complex network operation is fully automated; human-in-the-loop operation is critical. Given the complexity involved, there may be thousands of possible topological configurations at any given time. During an emergency, it is not uncommon for human operators to examine thousands of possible configurations in near real-time to choose the best option and operate the network effectively. In todays practice, network operation is largely based on experience with very limited real-time decision support, resulting in inadequate management of complex predictions and inability to anticipate, recognize, and respond to situations caused by human errors, natural disasters, and cyber attacks. A systematic approach is needed to manage the complex operation paradigms and choose the best option in a near-real-time manner. This paper applies predictive analytics techniques to establish a decision support system for complex network operation management and help operators to predict potential network failures and adapt the network to adverse situations. The resultant decision support system enables continuous monitoring of network performance and turns large amounts of data into actionable information. Examples with actual power grid data are presented to demonstrate the capability of this proposed decision support system.

Tetrahydrothiophene complexes of technetium(IV)  

Science Journals Connector (OSTI)

A technetium(IV) complex of the composition trans-[TcCl4(tht)2] (tht=tetrahydrothiophene) is formed during heating of \\{K2TcCl6\\} in a mixture of tht and aqueous HCl. The thioether ligands are only weakly bonded and the red crystals slowly decompose under release of tht. The weak technetiumsulphur bonds are confirmed by TcS distances of 2.494(1) . The anionic thioether technetium(IV) complex [TcBr5(tht)]? is formed by the reaction of (NBu4)2[TcBr6] with neat tht. The tetrabutylammonium salt of the complex is indefinitely stable in air.

Power grid vulnerability: A complex network approach  

Science Journals Connector (OSTI)

Power grids exhibit patterns of reaction to outages similar to complex networks. Blackout sequences follow power laws as complex systems operating near a critical point. Here the tolerance of electric power grids to both accidental and malicious outages is analyzed in the framework of complex network theory. In particular the quantity known as efficiency is modified by introducing a new concept of distance between nodes. As a result a new parameter called net-ability is proposed to evaluate the performance of power grids. A comparison between efficiency and net-ability is provided by estimating the vulnerability of sample networks in terms of both the metrics.

Explicit regulator maps on polylogarithmic motivic complexes.  

E-Print Network [OSTI]

We define a regulator map from the weight n polylogarithmic motivic complex to the weight n Deligne complex of an algebraic variety X. The regulator map is constructed explicitly via the classical polylogarithms with some funny combinations of Bernoulli numbers as coefficients. This leads to conjectures on special values of L-functions at s=n which reduce to Zagier's conjecture when X is of dimension zero over Q. The cone of this map, shifted by one, should be called the Arakelov motivic complex of X. Its last cohomology group is identified with a group of codimension n Arakelov cycles on X.

Actinide phosphonate complexes in aqueous solutions  

SciTech Connect (OSTI)

Complexes formed by actinides with carboxylic acids, polycarboxylic acids, and aminopolycarboxylic acids play a central role in both the basic and process chemistry of the actinides. Recent studies of f-element complexes with phosphonic acid ligands indicate that new ligands incorporating doubly ionizable phosphonate groups (-PO{sub 3}H{sub 2}) have many properties which are unique chemically, and promise more efficient separation processes for waste cleanup and environmental restoration. Simple diphosphonate ligands form much stronger complexes than isostructural carboxylates, often exhibiting higher solubility as well. In this manuscript recent studies of the thermodynamics and kinetics of f-element complexation by 1,1 and 1,2 diphosphonic acid ligands are described.

Symptoms of complexity in a tourism system  

E-Print Network [OSTI]

Tourism destinations behave as dynamic evolving complex systems, encompassing numerous factors and activities which are interdependent and whose relationships might be highly nonlinear. Traditional research in this field has looked after a linear approach: variables and relationships are monitored in order to forecast future outcomes with simplified models and to derive implications for management organizations. The limitations of this approach have become apparent in many cases, and several authors claim for a new and different attitude. While complex systems ideas are amongst the most promising interdisciplinary research themes emerged in the last few decades, very little has been done so far in the field of tourism. This paper presents a brief overview of the complexity framework as a means to understand structures, characteristics, relationships and explores the implications and contributions of the complexity literature on tourism systems. The objective is to allow the reader to gain a deeper appreciatio...

High?performance session variability compensation in forensic automatic speaker recognition.  

Science Journals Connector (OSTI)

Recently the main performance improvement in automatic speaker recognition technology has been due to session variability compensation techniques mainly based on factor analysis (FA) which have reduced the equal error rate (EER) of state?of?the?art systems by a factor of 10 in less than five years (e.g. EER<2% for NIST SRE 2008 telephonespeech). Moreover such systems are able to compute millions of comparisons a thousand times faster than real time after speech features are extracted. However some challenges remain because if there is a mismatch between the conditions of the FA training database and the speech used for comparison the effectiveness of the compensation significantly decreases. This problem is especially relevant in forensic voice comparison where the availability of speech matching operational conditions is usually sparse. In this presentation we show the impact of this effect in realistic simulated case studies. We use the BaezaAhumada IV database which contains speech acquired with the Spanish Guardia Civil facilities used in their daily work. We also present algorithms to handle sparsity in the data used for training FA models. Finally we outline future research plans in order to improve session variability compensation performance in forensically realistic conditions.
