    Highlights International Oil Markets Prices. We have found little need to adjust our oil price forecast from last month's report, since no evidence of significantly more bullish (or bearish) sentiment on the world oil market has arisen since last month. Our estimate from the December Outlook for the November imported oil cost still looks good at $23.50 and our current estimate for December's price at $24.75 is only slightly above last month's expected December level ($24.50). Thus, annual

    In 2006, the SciDAC Scientific Data Management (SDM) Center proposed to continue its work deploying leading edge data management and analysis capabilities to scientific applications. One of three thrust areas within the proposed center was focused on Scientific Process Automation (SPA) using workflow technology. As a founding member of the Kepler consortium [LAB+09], the SDM Center team was well positioned to begin deploying workflows immediately. We were also keenly aware of some of the deficiencies in Kepler when applied to high performance computing workflows, which allowed us to focus our research and development efforts on critical new capabilities which were ultimately integrated into the Kepler open source distribution, benefiting the entire community. Significant work was required to ensure Kepler was capable of supporting large-scale production runs for SciDAC applications. Our work on generic actors and templates have improved the portability of workflows across machines and provided a higher level of abstraction for workflow developers. Fault tolerance and provenance tracking were obvious areas for improvement within Kepler given the longevity and complexity of our target workflows. To monitor workflow execution, we developed and deployed a web-based dashboard. We then generalized this interface and released it so it could be deployed at other locations. Outreach has always been a primary focus of our work and we had many successful deployments across a number of scientific domains while continually publishing and presenting our work. This short paper describes our most significant accomplishments over the past 5 years. Additional information about the SDM Center can be found in the companion paper: The Scientific Data Management Center: Available Technologies and Highlights.

    U.S. Department of Energy (DOE) Cooperative Agreement DE-FC26-98FT40321 funded through the Office of Fossil Energy and administered at the National Energy Technology Laboratory (NETL) supported the performance of a Jointly Sponsored Research Program (JSRP) at the Energy & Environmental Research Center (EERC) with a minimum 50% nonfederal cost share to assist industry in commercializing and effectively applying highly efficient, nonpolluting energy systems that meet the nation's requirements for clean fuels, chemicals, and electricity in the 21st century. The EERC in partnership with its nonfederal partners jointly performed 131 JSRP projects for which the total DOE cost share was $22,716,634 (38%) and the nonfederal share was $36,776,573 (62%). Summaries of these projects are presented in this report for six program areas: (1) resource characterization and waste management, (2) air quality assessment and control, (3) advanced power systems, (4) advanced fuel forms, (5) value-added coproducts, and (6) advanced materials. The work performed under this agreement addressed DOE goals for reductions in CO{sub 2} emissions through efficiency, capture, and sequestration; near-zero emissions from highly efficient coal-fired power plants; environmental control capabilities for SO{sub 2}, NO{sub x}, fine respirable particulate (PM{sub 2.5}), and mercury; alternative transportation fuels including liquid synfuels and hydrogen; and synergistic integration of fossil and renewable resources.

    This publication provides a broad overview of the research programs and efforts being conducted, built, designed, and planned at Brookhaven National Laboratory. This work covers a broad range of scientific disciplines. Major facilities include the Alternating Gradient Synchrotron (AGS), with its newly completed booster, the National Synchrotron Light Source (NSLS), the High Flux Beam Reactor (HFBR), and the RHIC, which is under construction. Departments within the laboratory include the AGS department, accelerator development, physics, chemistry, biology, NSLS, medical, nuclear energy, and interdepartmental research efforts. Research ranges from the pure sciences, in nuclear physics and high energy physics as one example, to environmental work in applied science to study climatic effects, from efforts in biology which are a component of the human genome project to the study, production, and characterization of new materials. The paper provides an overview of the laboratory operations during 1992, including staffing, research, honors, funding, and general laboratory plans for the future.
