Hedge Funds: Regulators and Market Participants Are Taking Steps to Strengthen Market Discipline, but Continued Attention Is Needed

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Since the 1998 near collapse of Long-Term Capital Management (LTCM), a large hedge fund--a pooled investment vehicle that is privately managed and often engages in active trading of various types of securities and commodity futures and options--the number of hedge funds has grown, and they have attracted investments from institutional investors such as pension plans. Hedge funds generally are recognized… more

Federal Real Property: Strategy Needed to Address Agencies' Long-standing Reliance on Costly Leasing

Description: A letter report issued by the Government Accountability Office with an abstract that begins "In January 2003, GAO designated federal real property as a high-risk area, citing the government's overreliance on costly, long-term leasing as one of the major reasons. GAO's work over the years has shown that building ownership often costs less than operating leases, especially for long-term space needs. GAO was asked to identify (1) the profile of domestically held, federally leased space including t… more

Measurement of electron clouds in large accelerators by microwave dispersion

Description: Clouds of low energy electrons in the vacuum beam pipes of accelerators of positively charged particle beams present a serious limitation for operation at high currents. Furthermore, it is difficult to probe their density over substantial lengths of the beam pipe. We have developed a novel technique to directly measure the electron cloud density via the phase shift induced in a TE wave transmitted over a section of the accelerator and used it to measure the average electron cloud density over a… more

DYNA3D Material Model 71 - Solid Element Test Problem

Description: A general phenomenological-based elasto-plastic nonlinear isotropic strain hardening material model was implemented in DYNA3D for use in solid, beam, truss, and shell elements. The constitutive model, Model 71, is based upon conventional J2 plasticity and affords optional temperature and rate dependence (visco-plasticity). The expressions for strain hardening, temperature dependence, and rate dependence allow it to represent a wide variety of material responses. Options to capture temperature c… more

Parametric Modeling of Transverse Phase Space of an RF Photoinjector

Description: High brightness electron beam sources such as rf photo-injectors as proposed for SASE FELs must consistently produce the desired beam quality. We report the results of a study in which a combined neural network (NN) and first-principles (FP) model is used to model the transverse phase space of the beam as a function of quadrupole strength, while beam charge, solenoid field, accelerator gradient, and linac voltage and phase are kept constant. The parametric transport matrix between the exit of t… more

Absolute Bunch Length Measurements at the ALS by Incoherent Synchrotron Radiation Fluctuation Analysis

Description: By analyzing the pulse to pulse intensity fluctuations of the radiation emitted by a charge particle in the incoherent part of the spectrum, it is possible to extract information about the spatial distribution of the beam. At the Advanced Light Source (ALS) of the Lawrence Berkeley National Laboratory, we have developed and tested a simple scheme based on this principle that allows for the absolute measurement of the bunch length. A description of the method and the experimental results are pre… more

Modeling Incoherent Electron Cloud Effects

Description: Incoherent electron effects could seriously limit the beam lifetime in proton or ion storage rings, such as LHC, SPS, or RHIC, or blow up the vertical emittance of positron beams, e.g., at the B factories or in linear-collider damping rings. Different approaches to modeling these effects each have their own merits and drawbacks. We describe several simulation codes which simplify the descriptions of the beam-electron interaction and of the accelerator structure in various different ways, and pr… more

Multi-Probe Investigation of Proteomic Structure of Pathogens

Description: Complete genome sequences are available for understanding biotransformation, environmental resistance and pathogenesis of microbial, cellular and pathogen systems. The present technological and scientific challenges are to unravel the relationships between the organization and function of protein complexes at cell, microbial and pathogens surfaces, to understand how these complexes evolve during the bacterial, cellular and pathogen life cycles, and how they respond to environmental changes, che… more

Military Operations: Implementation of Existing Guidance and Other Actions Needed to Improve DOD's Oversight and Management of Contractors in Future Operations

Description: Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) relies extensively on contractors to support deployed forces for services that range from food and housing services to intelligence analysis. Since 1997, GAO has reported on DOD's shortcomings in managing and overseeing its use of contractor support.
