Analysis of HLA-DP association with beryllium disease susceptibility in pooled exposed populations (open access)

Analysis of HLA-DP association with beryllium disease susceptibility in pooled exposed populations

Berylliosis or Chronic Beryllium Disease is a chronic granulomatous disorder primarily involving the lung associated with the exposition to low doses of Beryllium (Be) in the workplace. Berylliosis risk has been associated with the presence of a glutamate at position 69 of the HLA-DP beta chain (HLA-DPbetaGlu69) that is expressed in about 97% of disease cases and in 27% of the unaffected Be-exposed controls (p<0.0001) (Richeldi et al. Science 1993; 262: 242-244.12). Since this first observation of an immunogenetic association between berylliosis and HLA-DPbetaGlu69 a number of studies have confirmed the role of this marker as the primary gene of susceptibility of berylliosis (Richeldi et al Am J Ind Med. 1997; 32:337-40; Wang et al J. Immunol. 1999; 163: 1647-53; Saltini et al Eur Respir J. 2001 18:677-84; Rossman et al Am J Respir Crit Care Med. 2002 165:788-94). Moreover, a structure/function interaction between HLA-DP molecules carrying Glu69 and beryllium in driving and developing the immune response against beryllium itself has been observed as: (1) Be-specific T-cells clones obtained from berylliosis patients recognize beryllium as antigen only when presented in the context of the HLA-DP{beta}Glu69 molecules but not in the context of HLA-DP allelic variants carrying Lys69 (Lombardi G et …

Beam dynamics of the Neutralized Drift Compression Experiment-II (NDCX-II),a novel pulse-compressing ion accelerator (open access)

Beam dynamics of the Neutralized Drift Compression Experiment-II (NDCX-II),a novel pulse-compressing ion accelerator

Intense beams of heavy ions are well suited for heating matter to regimes of emerging interest. A new facility, NDCX-II, will enable studies of warm dense matter at {approx}1 eV and near-solid density, and of heavy-ion inertial fusion target physics relevant to electric power production. For these applications the beam must deposit its energy rapidly, before the target can expand significantly. To form such pulses, ion beams are temporally compressed in neutralizing plasma; current amplification factors of {approx}50-100 are routinely obtained on the Neutralized Drift Compression Experiment (NDCX) at LBNL. In the NDCX-II physics design, an initial non-neutralized compression renders the pulse short enough that existing high-voltage pulsed power can be employed. This compression is first halted and then reversed by the beam's longitudinal space-charge field. Downstream induction cells provide acceleration and impose the head-to-tail velocity gradient that leads to the final neutralized compression onto the target. This paper describes the discrete-particle simulation models (1-D, 2-D, and 3-D) employed and the space-charge-dominated beam dynamics being realized.

Advances in Bayesian Model Based Clustering Using Particle Learning (open access)

Advances in Bayesian Model Based Clustering Using Particle Learning

Recent work by Carvalho, Johannes, Lopes and Polson and Carvalho, Lopes, Polson and Taddy introduced a sequential Monte Carlo (SMC) alternative to traditional iterative Monte Carlo strategies (e.g. MCMC and EM) for Bayesian inference for a large class of dynamic models. The basis of SMC techniques involves representing the underlying inference problem as one of state space estimation, thus giving way to inference via particle filtering. The key insight of Carvalho et al was to construct the sequence of filtering distributions so as to make use of the posterior predictive distribution of the observable, a distribution usually only accessible in certain Bayesian settings. Access to this distribution allows a reversal of the usual propagate and resample steps characteristic of many SMC methods, thereby alleviating to a large extent many problems associated with particle degeneration. Furthermore, Carvalho et al point out that for many conjugate models the posterior distribution of the static variables can be parametrized in terms of [recursively defined] sufficient statistics of the previously observed data. For models where such sufficient statistics exist, particle learning as it is being called, is especially well suited for the analysis of streaming data do to the relative invariance of its algorithmic complexity …

Credit Cards: Rising Interchange Fees Have Increased Costs for Merchants, but Options for Reducing Fees Pose Challenges (open access)

Credit Cards: Rising Interchange Fees Have Increased Costs for Merchants, but Options for Reducing Fees Pose Challenges

A letter report issued by the Government Accountability Office with an abstract that begins "When a consumer uses a credit card to make a purchase, the merchant does not receive the full purchase amount because a certain portion of the sale is deducted to compensate the merchant's bank, the bank that issued the card, and the card network that processes the transaction. The level and growth of these rates have become increasingly controversial. The 2009 Credit Card Accountability, Responsibility, and Disclosure Act directed GAO to review (1) how the fees merchants pay have changed over time and the factors affecting the competitiveness of the credit card market, (2) how credit card competition has affected consumers, (3) the benefits and costs to merchants of accepting cards and their ability to negotiate those costs, and (4) the potential impact of various options intended to lower merchant costs. To address these objectives, GAO reviewed and analyzed relevant studies, literature, and data on the card payment market and interviewed industry participants, including large and small card issuers (including community banks and credit unions), card processors, card networks, large merchants representing a significant proportion of retail sales, and small merchants from a variety of industries, …

Defense Health Care: Post-Deployment Health Reassessment Documentation Needs Improvement (open access)

Defense Health Care: Post-Deployment Health Reassessment Documentation Needs Improvement

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) implemented the post-deployment health reassessment (PDHRA), which is required to be administered to servicemembers 90 to 180 days after their return from deployment. DOD established the PDHRA program to identify and address servicemembers' health concerns that emerge over time following deployments. This report is the second in response to a Senate Armed Services Committee report directing the Government Accountability Office (GAO) to review DOD's administration of the PDHRA, and to additional congressional requests. In this report, GAO examined (1) the extent to which DOD's central repository contains PDHRA questionnaires for active and Reserve component servicemembers who returned from deployment to Iraq or Afghanistan and (2) how DOD monitors the administration of the PDHRA to Reserve component servicemembers. To conduct this review, GAO performed a quantitative analysis using DOD deployment and PDHRA data, reviewed relevant PDHRA policies, and interviewed DOD officials."

Grant Monitoring: Department of Education Could Improve Its Processes with Greater Focus on Assessing Risks, Acquiring Financial Skills, and Sharing Information

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Education (Education) awards about $45 billion in grants each year to school districts, states, and other entities. In addition, the American Recovery and Reinvestment Act of 2009 provided an additional $97 billion in grant funding. In a series of reports from 2002 to 2009, Education's Inspector General cited a number of grantees for failing to comply with financial and programmatic requirements of their grant agreements. GAO was asked to determine: (1) what progress Education has made in implementing a risk-based approach to grant monitoring, (2) to what extent Education's program offices have the expertise necessary to monitor grantees' compliance with grant program requirements, and (3) to what extent information is shared and used within Education to ensure the effectiveness of grant monitoring. To do this, GAO reviewed agency documentation related to Education's internal controls and interviewed senior Education officials and staff in 12 of the 34 offices that monitor grants."

Homeland Security: Key US-VISIT Components at Varying Stages of Completion, but Integrated and Reliable Schedule Needed

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security's (DHS) U.S. Visitor and Immigrant Status Indicator Technology (US-VISIT) program stores and processes biometric and biographic information to, among other things, control and monitor the entry and exit of foreign visitors. Currently, an entry capability is operating at almost 300 U.S. ports of entry, but an exit capability is not. The Government Accountability Office (GAO) has previously reported on limitations in DHS's efforts to plan and execute its efforts to deliver US-VISIT exit, and made recommendations to improve these areas. GAO was asked to determine (1) the status of DHS's efforts to deliver a comprehensive exit solution and (2) to what extent DHS is applying an integrated approach to managing its comprehensive exit solution. To accomplish this, GAO assessed US-VISIT exit project plans, schedules, and other management documentation against relevant criteria, and it observed exit pilots."

Information Technology and Community Restoration Studies/Task 1: Information Technology

Executive Summary The Interagency Biological Restoration Demonstration—a program jointly funded by the Department of Defense's Defense Threat Reduction Agency and the Department of Homeland Security's (DHS's) Science and Technology Directorate—is developing policies, methods, plans, and applied technologies to restore large urban areas, critical infrastructures, and Department of Defense installations following the intentional release of a biological agent (anthrax) by terrorists. There is a perception that there should be a common system that can share information both vertically and horizontally amongst participating organizations as well as support analyses. A key question is: "How far away from this are we?" As part of this program, Pacific Northwest National Laboratory conducted research to identify the current information technology tools that would be used by organizations in the greater Seattle urban area in such a scenario, to define criteria for use in evaluating information technology tools, and to identify current gaps. Researchers interviewed 28 individuals representing 25 agencies in civilian and military organizations to identify the tools they currently use to capture data needed to support operations and decision making. The organizations can be grouped into five broad categories: defense (Department of Defense), environmental/ecological (Environmental Protection Agency/Ecology), public health and medical services, emergency management, …

UN Office for Project Services: Management Reforms Proceeding but Effectiveness Not Assessed, and USAID's Oversight of Grants Has Weaknesses

A letter report issued by the Government Accountability Office with an abstract that begins "The United Nations (UN) Office for Project Services (UNOPS) provides numerous services for its clients, including procurement and project management. Recent audits and investigations of UNOPS have revealed alleged violations of law, weak internal controls, and financial mismanagement. UNOPS officials misused some of the more than $400 million awarded to UNOPS by the U.S. Agency for International Development (USAID) from 2004 through 2008. GAO was asked to (1) assess the extent to which UNOPS has addressed key concerns about its internal controls, and (2) evaluate USAID's oversight of UNOPS-implemented projects. To address these objectives, GAO reviewed UNOPS and USAID policies and grant documentation."
