Biologically Enhanced Carbon Sequestration: Research Needs and Opportunities (open access)

Biologically Enhanced Carbon Sequestration: Research Needs and Opportunities

Fossil fuel combustion, deforestation, and biomass burning are the dominant contributors to increasing atmospheric carbon dioxide (CO{sub 2}) concentrations and global warming. Many approaches to mitigating CO{sub 2} emissions are being pursued, and among the most promising are terrestrial and geologic carbon sequestration. Recent advances in ecology and microbial biology offer promising new possibilities for enhancing terrestrial and geologic carbon sequestration. A workshop was held October 29, 2007, at Lawrence Berkeley National Laboratory (LBNL) on Biologically Enhanced Carbon Sequestration (BECS). The workshop participants (approximately 30 scientists from California, Illinois, Oregon, Montana, and New Mexico) developed a prioritized list of research needed to make progress in the development of biological enhancements to improve terrestrial and geologic carbon sequestration. The workshop participants also identified a number of areas of supporting science that are critical to making progress in the fundamental research areas. The purpose of this position paper is to summarize and elaborate upon the findings of the workshop. The paper considers terrestrial and geologic carbon sequestration separately. First, we present a summary in outline form of the research roadmaps for terrestrial and geologic BECS. This outline is elaborated upon in the narrative sections that follow. The narrative sections start with the …

Center-stabilized Yang-Mills Theory:Confinement and Large N Volume Independence (open access)

Center-stabilized Yang-Mills Theory:Confinement and Large N Volume Independence

We examine a double trace deformation of SU(N) Yang-Mills theory which, for large N and large volume, is equivalent to unmodified Yang-Mills theory up to O(1/N{sup 2}) corrections. In contrast to the unmodified theory, large N volume independence is valid in the deformed theory down to arbitrarily small volumes. The double trace deformation prevents the spontaneous breaking of center symmetry which would otherwise disrupt large N volume independence in small volumes. For small values of N, if the theory is formulated on R{sup 3} x S{sup 1} with a sufficiently small compactification size L, then an analytic treatment of the non-perturbative dynamics of the deformed theory is possible. In this regime, we show that the deformed Yang-Mills theory has a mass gap and exhibits linear confinement. Increasing the circumference L or number of colors N decreases the separation of scales on which the analytic treatment relies. However, there are no order parameters which distinguish the small and large radius regimes. Consequently, for small N the deformed theory provides a novel example of a locally four-dimensional pure gauge theory in which one has analytic control over confinement, while for large N it provides a simple fully reduced model for Yang-Mills theory. …

First Quarter Hanford Seismic Report for Fiscal Year 2008 (open access)

First Quarter Hanford Seismic Report for Fiscal Year 2008

The Hanford Seismic Assessment Program (HSAP) provides an uninterrupted collection of high-quality raw and processed seismic data from the Hanford Seismic Network for the U.S. Department of Energy and its contractors. The Hanford Seismic Assessment Team locates and identifies sources of seismic activity and monitors changes in the historical pattern of seismic activity at the Hanford Site. The data are compiled, archived, and published for use by the Hanford Site for waste management, natural phenomena hazards assessments, and engineering design and construction. In addition, the seismic monitoring organization works with the Hanford Site Emergency Services Organization to provide assistance in the event of a significant earthquake on the Hanford Site. The Hanford Seismic Network and the Eastern Washington Regional Network consist of 41 individual sensor sites and 15 radio relay sites maintained by the Hanford Seismic Assessment Team. For the Hanford Seismic Network, forty-four local earthquakes were recorded during the first quarter of fiscal year 2008. A total of thirty-one micro earthquakes were recorded within the Rattlesnake Mountain swarm area at depths in the 5-8 km range, most likely within the pre-basalt sediments. The largest event recorded by the network during the first quarter (November 25, 2007 - magnitude 1.5 …

The Nation's Long-Term Fiscal Outlook: January 2008 Update

Correspondence issued by the Government Accountability Office with an abstract that begins "Since 1992, GAO has published long-term fiscal simulations of what might happen to federal deficits and debt levels under varying policy assumptions. We developed our long-term model in response to a bipartisan request from Members of Congress who were concerned about the long-term effects of fiscal policy. Our simulations were updated with Congressional Budget Office (CBO's) January budget and economic projections and continue to indicate that the long-term federal fiscal outlook remains unsustainable. This update combined with our analysis of the fiscal outlook of state and local governments demonstrates that the fiscal challenges facing all levels of government are linked and should be considered in a strategic and integrated manner. We update our simulations three times a year as new estimates become available from CBO's Budget and Economic Outlook (January), Social Security and Medicare Trustees Reports (spring), and CBO's Budget and Economic Outlook: An Update (late summer). This product responds to congressional interest in receiving updated simulation results."

Optics and multilayer coatings for EUVL systems (open access)

Optics and multilayer coatings for EUVL systems

EUV lithography (EUVL) employs illumination wavelengths around 13.5 nm, and in many aspects it is considered an extension of optical lithography, which is used for the high-volume manufacturing (HVM) of today's microprocessors. The EUV wavelength of illumination dictates the use of reflective optical elements (mirrors) as opposed to the refractive lenses used in conventional lithographic systems. Thus, EUVL tools are based on all-reflective concepts: they use multilayer (ML) coated optics for their illumination and projection systems, and they have a ML-coated reflective mask.

U.S. Coins: The Federal Reserve Banks Are Fulfilling Coin Demand, but Optimal Inventory Ranges Are Undefined (open access)

U.S. Coins: The Federal Reserve Banks Are Fulfilling Coin Demand, but Optimal Inventory Ranges Are Undefined

A letter report issued by the Government Accountability Office with an abstract that begins "Federal Reserve Banks fulfill the coin demand of the nation's depository institutions--which include commercial banks, savings and loan associations, and credit unions--by ordering new coins from the U.S. Mint and managing coins held in inventory at the Reserve Banks and in coin terminals. Reliably estimating the demand for coins and efficiently managing the inventory of circulated coins is important to ensure that depository institutions have enough coins to meet the public's demand and to avoid unnecessary coin production costs. Since late 2006, rising metal prices have driven the costs of producing pennies and nickels above the face values of the coins. This report addresses (1) the Reserve Banks' process for ordering and distributing coins to the nation's depository institutions and (2) the extent to which this process meets depository institutions' demand for coins. GAO interviewed officials responsible for coin distribution at each of the 12 Reserve Banks and met with representatives of 4 large operators of Federal Reserve coin terminals, 2 banking associations, the U.S. Mint, and the nation's largest coin recycling company. GAO also analyzed Reserve Bank data for fiscal years 1993 through 2007. Federal …

Using Perturbed QR Factorizations To Solve Linear Least-Squares Problems (open access)

Using Perturbed QR Factorizations To Solve Linear Least-Squares Problems

We propose and analyze a new tool to help solve sparse linear least-squares problems min{sub x} {parallel}Ax-b{parallel}{sub 2}. Our method is based on a sparse QR factorization of a low-rank perturbation {cflx A} of A. More precisely, we show that the R factor of {cflx A} is an effective preconditioner for the least-squares problem min{sub x} {parallel}Ax-b{parallel}{sub 2}, when solved using LSQR. We propose applications for the new technique. When A is rank deficient we can add rows to ensure that the preconditioner is well-conditioned without column pivoting. When A is sparse except for a few dense rows we can drop these dense rows from A to obtain {cflx A}. Another application is solving an updated or downdated problem. If R is a good preconditioner for the original problem A, it is a good preconditioner for the updated/downdated problem {cflx A}. We can also solve what-if scenarios, where we want to find the solution if a column of the original matrix is changed/removed. We present a spectral theory that analyzes the generalized spectrum of the pencil (A*A,R*R) and analyze the applications.
