The In-Between World of the Mesoscale

by Kathy Chambers 23 Jun, 2015 in

Argonne Leadership Computing Facility, Brown University: Brain blood flow simulation with NekTar; a continuum modelArgonne Leadership Computing Facility, Brown University: Brain blood flow simulation with NekTar; a continuum modelEmerging mesoscale science opportunities are among the most promising for future research.  The in-between world of the mesoscale connects the microscopic objects (atoms and molecules) and macroscopic assemblies (chemically and structurally complex bulk materials) worlds, giving a complete picture – the emergence of new phenomena, the understanding of behaviors, and the role imperfections play in determining performance.  Because of the ever-accelerating advances in modern experimental, theoretical, and computational capabilities, Department of Energy (DOE) researchers are now realizing unprecedented scientific achievements with mesoscale science.  

George Em Karniadakis is one of the notable mesoscale researchers who are changing what we know about medicine.  Dr. Karniadakis, a joint appointee with Pacific Northwest National Laboratory and Brown University, serves as principal investigator and director of the Collaboratory on Mathematics for Mesoscopic Modeling of Materials (CM4), a major project sponsored by the Applied Mathematics Program within the DOE’s Office of Advanced Scientific Computing Research (ASCR).  CM4 focuses on developing rigorous mathematical foundations for understanding and controlling fundamental mechanisms in mesoscale processes to enable scalable synthesis of complex materials.

SciTech Connect, Primary Repository for DOE Scientific and Technical Information, Turns Two

by Catherine Pepmiller 02 Apr, 2015 in Products and Content

As Spring 2015 rolls around, it’s time to mark a momentous occasion in the history of SciTech Connect: it’s turning TWO! 

SciTech Connect is a publicly available database of bibliographic citations for energy-related scientific and technical information (STI), including technical reports, journal articles, conference papers, books, multimedia, and data information.  Launched in March 2013 by the Department of Energy (DOE) Office of Scientific and Technical Information (OSTI), SciTech Connect incorporated the contents of two of the most popular core DOE collections, DOE Information Bridge and Energy Citations Database, and employed an innovative semantic search tool and updated interface to enable scientists, researchers, and the public to retrieve more relevant information.  SciTech Connect has emerged as a go-to resource, becoming OSTI’s most-visited repository for DOE science, technology, and engineering research information.  Currently, it offers users over 2.7 million citations, including 400,000 full-text documents  and nearly 1.5 million journal article citations, 240,000 of which have digital object identifiers (DOIs) with links to publishers’ websites.

DOE Open Government Plan 3.0 Highlights OSTI Products

by Peter Lincoln 24 Jun, 2014 in

The Department of Energy recently issued its latest Open Government Plan, and the document recognizes the DOE Office of Scientific and Technical Information (OSTI) for advancing open government and the principles of transparency, participation, and collaboration by making scientific and technical information (STI) publicly available.

OSTI Is Re-Focusing and Re-Balancing Its Operations – And Refreshing Its Home Page – to Advance Public Access

by Dr. Jeffrey Salmon 03 Mar, 2014 in Products and Content
Scientific and Technical Information Program:  STI from DOE Programs, Labs, MajS

Let’s call it creative destruction, borrowing from a popular term in economics.  The idea is that the very essence of capitalism is the destruction of old structures and the building of new ones that inevitably face the same pressures as the structures they replaced.  It’s the reason the buggy whip industry fell on hard times. The information management business of the Office of Scientific and Technical Information (OSTI) is in constant flux too, where the next big thing can soon become the next big flop.

Titan Cray XK7 at Oak Ridge National Laboratory

Just seven miles south of our OSTI facility in Oak Ridge, Tennessee is a national treasure – the Oak Ridge National Laboratory (ORNL).  ORNL is DOE’s largest multi-program laboratory where remarkable scientific expertise and world-class scientific facilities and equipment are applied to develop scientific and technological solutions that are changing our world. ORNL’s National Center for Computational Sciences is home to two of ORNL’s high-performance computing projects -- the National Climate-Computing Research Center (NCRC), where research is dedicated to climate science, and the Oak Ridge Leadership Computing Facility (OLCF)

Before and after CrossRef

Aquatint of a Doctor in divinity at the University of Oxford, shown wearing conv

It is truly wonderful when something comes along that speeds access to science. Such is the case with CrossRef’s linking network for scholarly literature. Anyone that has ever done a literature search prior to 2000 is completely blown away today when they encounter the time saved and the quality of CrossRef’s linking service. I vividly recall my own literature review for my PhD dissertation almost 40 years ago and I want to share my story.

For many long and miserable days and nights for a solid month I practically lived at the University of Maryland’s Engineering and Physical Sciences Library plowing through a massive set of numerous volumes of citation indices looking up keywords related to my dissertation. My topic Secondary deflections and lateral stability of beams was based on my research at the U.S. Naval Research Laboratory.

Observing Gamma-ray Bursts in Distant Galaxies

by Kathy Chambers 21 Nov, 2013 in Science Communications
Gamma-ray burst  GRB 080319B

Star gazing seems especially good on a clear autumn night. From our back deck our amateur eyes scan the sky and its wonder. We first notice Venus, our closest planetary neighbor. A beautiful harvest moon rises over the hill, lighting up jet streams that crisscross the stars and planets. We see Orion, the bowl and handle of the Big Dipper, the Square of Pegasus, the vast Milky Way and we are fortunate to see an occasional falling star. We are in awe of the beauty of our night sky but it’s what we can’t see that is truly amazing.

Spectacular explosions, which can’t be detected with the human eye, light up the gamma-ray sky about once a day. These explosions, called gamma-ray bursts (GRBs), are from distant galaxies hundreds of millions of light years away from earth and are thought to be triggered by supernovae or exploding stars. They release more energy than our sun will put out in a lifetime.

Name Ambiguity and ORCID

by Tim Byrne 28 Oct, 2013 in Science Communications

Wouldn’t it be nice if your name were a unique identifier and nobody else had the same name as you?  Unfortunately, most of us share our names with a number of other people, most of whom we have never met and never will.  But we have all probably experienced the challenge and frustration of trying to find a specific person from a list of people with the same name.  Remember when we used phone books?  Trying to pick out the person you needed from a listing of multiple names?  Actually, searching the internet doesn’t make this process any easier.

Turning points in history – things or events that define lasting change in the world we know.  The industrial revolution, Henry Ford’s automobile, penicillin, Einstein’s theory of relativity, firsts in aviation and space, the discovery of electricity, and the digital computer invention were some of these turning points.

SciTech Connect: Subject and Author Filters

by Tim Byrne 25 Jul, 2013 in Products and Content

One of the nice features of SciTech Connect is the ability to filter search results by subject and author.  On the Search Results page, these filters are midway down the left side.

The full SciTech Connect database contains over 2.5 million citations.  Filtering the full database by subject [23 MB AVI] shows the top subject in the database to be materials science with 184,200 citations.  Not too far down the top ten list you will also find materials with another 127,916 citations.
