The Berry Amendment: Requiring Defense Procurement to Come from Domestic Sources (open access)

The Berry Amendment: Requiring Defense Procurement to Come from Domestic Sources

The Berry Amendment requires the Department of Defense (DOD) to give preference in procurement to domestically produced, manufactured, or home grown products, notably food, clothing, fabrics, and specialty metals. In order to protect the U.S. industrial base during periods of adversity and war, Congress passed domestic source restrictions as part of the 1941 Fifth Supplemental DOD Appropriations Act; these provisions later became the Berry Amendment. This report examines the original intent and purpose of the Berry Amendment, legislative proposals to amend the application of domestic source restrictions, as well as options for Congress.

Conceptual Design of an Antiproton Generation and Storage Facility (open access)

Conceptual Design of an Antiproton Generation and Storage Facility

The Antiproton Generation and Storage Facility (AGSF) creates copious quantities of antiprotons, for bottling and transportation to remote cancer therapy centers. The #12;first step in the generation and storage process is to accelerate an intense proton beam down the Main Linac for injection into the Main Ring, which is a Rapid Cycling Synchrotron that accelerates the protons to high energy. The beam is then extracted from the ring into a transfer line and into a Proton Target. Immediately downstream of the target is an Antiproton Collector that captures some of the antiprotons and focuses them into a beam that is transported sequentially into two antiproton rings. The Precooler ring rapidly manipulates antiproton bunches from short and broad (in momentum) to long and thin. It then performs some preliminary beam cooling, in the fraction of a second before the next proton bunch is extracted from the Main Ring. Pre-cooled antiprotons are passed on to the Accumulator ring before the next antiprotons arrive from the target. The Accumulator ring cools the antiprotons, compressing them into a dense state that is convenient for mass storage over many hours. Occasionally the Accumulator ring decelerates a large number of antiprotons, injecting them into a Deceleration …

Coulomb Excitation of the 242mAm Isomer (open access)

Coulomb Excitation of the 242mAm Isomer

The {sup 242m}Am isomer, a well-known candidate for photo-depopulation research, has been studied in this first ever Coulomb excitation of a nearly pure ({approx} 98%) isomer target. Thirty new states, including a new rotational band built on a K{sup {pi}} = 6{sup -} state have been identified. Strong K-mixing results in nearly equal populations of the K{sup {pi}} = 5{sup -} and 6{sup -} states. Newly identified states have been assigned to the K{sup {pi}} = 3{sup -} rotational band, the lowest states of which are known to decay into the ground-state band. Implications regarding K-mixing and Coulomb excitation paths to the ground state are discussed.

Developing Livestock Facility Type Information from USDA Agricultural Census Data for Use in Epidemiological and Economic Models (open access)

Developing Livestock Facility Type Information from USDA Agricultural Census Data for Use in Epidemiological and Economic Models

The epidemiological and economic modeling of livestock diseases requires knowing the size, location, and operational type of each livestock facility within the US. At the present time, the only national database of livestock facilities that is available to the general public is the USDA's 2002 Agricultural Census data, published by the National Agricultural Statistics Service, herein referred to as the 'NASS data.' The NASS data provides facility data at the county level for various livestock types (i.e., beef cows, milk cows, cattle on feed, other cattle, total hogs and pigs, sheep and lambs, milk goats, and angora goats). However, the number and sizes of facilities for the various livestock types are not independent since some facilities have more than one type of livestock, and some livestock are of more than one type (e.g., 'other cattle' that are being fed for slaughter are also 'cattle on feed'). In addition, any data tabulated by NASS that could identify numbers of animals or other data reported by an individual respondent is suppressed by NASS and coded with a 'D.'. To be useful for epidemiological and economic modeling, the NASS data must be converted into a unique set of facility types (farms having similar …

The First Estimate of BR(\bar B to X_s\gamma) at O(\alpha_s^2) (open access)

The First Estimate of BR(\bar B to X_s\gamma) at O(\alpha_s^2)

Combining our results for various {Omicron}({alpha}{sub s}{sup 2}) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next-to-leading order in QCD. We find {Beta}({bar B} {yields} X{sub s}{gamma}) = (3.15 {+-} 0.23) x 10{sup -4} for E{sub {gamma}} > 1.6 GeV in the {bar B}-meson rest frame. The four types of uncertainties: non-perturbative (5%), parametric (3%), higher-order (3%) and m{sub c}-interpolation ambiguity (3%) have been added in quadrature to obtain the total error.

Flux Compactification (open access)

Flux Compactification

We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological constant, features needed to reproduce real world physics. We explain how this work implies that there is a ''landscape'' of string/M theory vacua, perhaps containing many candidates for describing real world physics, and present the arguments for and against this idea. We discuss statistical surveys of the landscape, and the prospects for testable consequences of this picture, such as observable effects of moduli, constraints on early cosmology, and predictions for the scale of supersymmetry breaking.

Frequency Analysis of Aircraft hazards for License Application (open access)

Frequency Analysis of Aircraft hazards for License Application

The preclosure safety analysis for the monitored geologic repository at Yucca Mountain must consider the hazard that aircraft may pose to surface structures. Relevant surface structures are located beneath the restricted airspace of the Nevada Test Site (NTS) on the eastern slope of Yucca Mountain, near the North Portal of the Exploratory Studies Facility Tunnel (Figure 1). The North Portal is located several miles from the Nevada Test and Training Range (NTTR), which is used extensively by the U.S. Air Force (USAF) for training and test flights (Figure 1). The NTS airspace, which is controlled by the U.S. Department of Energy (DOE) for NTS activities, is not part of the NTTR. Agreements with the DOE allow USAF aircraft specific use of the airspace above the NTS (Reference 2.1.1 [DIRS 103472], Section 3.1.1 and Appendix A, Section 2.1; and Reference 2.1.2 [DIRS 157987], Sections 1.26 through 1.29). Commercial, military, and general aviation aircraft fly within several miles to the southwest of the repository site in the Beatty Corridor, which is a broad air corridor that runs approximately parallel to U.S. Highway 95 and the Nevada-California border (Figure 2). These aircraft and other aircraft operations are identified and described in ''Identification of …

Gauge/gravity Duality and MetastableDynamical Supersymmetry Breaking (open access)

Gauge/gravity Duality and MetastableDynamical Supersymmetry Breaking

We engineer a class of quiver gauge theories with several interesting features by studying D-branes at a simple Calabi-Yau singularity. At weak 't Hooft coupling we argue using field theory techniques that these theories admit both supersymmetric vacua and meta-stable non-supersymmetric vacua, though the arguments indicating the existence of the supersymmetry breaking states are not decisive. At strong 't Hooft coupling we find simple candidate gravity dual descriptions for both sets of vacua.

Health Professional Shortage Areas: Problems Remain with Primary Care Shortage Area Designation System (open access)

Health Professional Shortage Areas: Problems Remain with Primary Care Shortage Area Designation System

A letter report issued by the Government Accountability Office with an abstract that begins "To identify areas facing shortages of health care providers, the Department of Health and Human Services (HHS) relies on its health professional shortage area (HPSA) designation system. HHS designates geographic, population-group, and facility HPSAs. HHS also gives each HPSA a score to rank its need for providers relative to other HPSAs. The Health Care Safety Net Amendments of 2002 required GAO to report on the HPSA designation system. GAO reviewed (1) the number and location of HPSAs and federal programs that use HPSA designations to allocate resources or provide benefits, (2) available research on HPSA designation criteria and methodology, and (3) the impact of a 2002 provision that automatically designates federally qualified health centers and certain rural health clinics as facility HPSAs. GAO obtained and analyzed HHS's data on primary care HPSA designations as of September 2005 and January 2006 and identified reports on HPSA criteria and methodology through a literature search of peer-reviewed journals and other reports published since 1995."

Most of rare missense alleles in humans are deleterious:implications for evolution of complex disease and associationstudies (open access)

Most of rare missense alleles in humans are deleterious:implications for evolution of complex disease and associationstudies

The accumulation of mildly deleterious missense mutations inindividual human genomes has been proposed to be a genetic basis forcomplex diseases. The plausibility of this hypothesis depends onquantitative estimates of the prevalence of mildly deleterious de novomutations and polymorphic variants in humans and on the intensity ofselective pressure against them. We combined analysis of mutationscausing human Mendelian diseases, human-chimpanzee divergence andsystematic data on human SNPs and found that about 20 percent of newmissense mutations in humans result in a loss of function, while about 27percent are effectively neutral. Thus, more than half of new missensemutations have mildly deleterious effects. These mutations give rise tomany low frequency deleterious allelic variants in the human populationas evident from a new dataset of 37 genes sequenced in over 1,500individual human chromosomes. Surprisingly, up to 70 percent of lowfrequency missense alleles are mildly deleterious and associated with aheterozygous fitness loss in the range 0.001-0.003. Thus, the low allelefrequency of an amino acid variant can by itself serve as a predictor ofits functional significance. Several recent studies have reported asignificant excess of rare missense variants in disease populationscompared to controls in candidate genes or pathways. These studies wouldbe unlikely to work if most rare variants were neutral …
