Recent times have witnessed an increase in use of high-performance reconfigurable computing for accelerating large-scale simulations. A characteristic of such simulations, like infrared (IR) scene simulation, is the use of large quantities of uncorrelated random numbers. It is therefore of interest to have a fast uniform random number generator implemented in reconfigurable hardware. While ther...

Based on the predicted capacity to interact with membranes at the interface, we have found three regions in the ectodomain of the hepatitis C virus envelope glycoprotein E2 (430-449, 543-560 and 603-624) with the ability to destabilize membranes. Three peptides corresponding to the sequence of these regions have been synthesized and their interaction with liposomes have been characterized. The ...

A unitary multi-channel approach, first developed by the Carnegie-MellonBerkeley group, is applied to extract the pole positions, masses, and partial decay widths of nucleon resonances from the partial wave amplitudes for the transitions from πN to eight possible final baryon-meson states. Results of single energy analyses of the VPI group using the most current database are used in this analys...

I consider in this paper the impact of insider trading regulation (ITR) on a securities markets and on social welfare, and suggest that society would be better off if ITR were eliminated. In addition, acknowledging that such an abrupt change in policy is not likely to be made, at least in the short run, I propose two alternative policies, both consisting of allowing insider trading and imposing...

PURPOSE To identify racial/ethnic differences in retention of older adults at 3 levels of participation in a prospective observational study: telephone, in-home assessments, and home visits followed by blood draws. DESIGN AND METHODS A prospective study of 1,000 community-dwelling Medicare beneficiaries aged 65 years and older included a baseline in-home assessment and telephone follow-up cal...

This paper presents a model where agents decide on the timing of replacement of ageing machines. The optimal replacement policy for an agent is influenced by other agents’ decisions because the productivity of a particular vintage displays network externalities that set in with a lag. In equilibrium, agents follow innovation cycles with a frequency that is lower than optimal, so there is too mu...

We present models of the shapes of four Kuiper belt objects (KBOs) and Jovian Trojan (624) Hektor as ellipsoidal figures of equilibrium and Roche binaries. Our simulations select those figures of equilibrium whose lightcurves best match the measured rotational data. The best fit shapes, combined with the knowledge of the spin period of the objects provide estimates of the bulk densities of thes...

BACKGROUND The burden of silicosis, pulmonary tuberculosis and COPD is described in 624 South African gold miners 18 months after cessation of work. METHODS This was a prevalence study. Questionnaires were administered, and spirometry, chest radiography, tuberculosis investigations, and urine HIV antibody assays were performed. RESULTS Attendance was 80.1% (624/779), mean age 49.4 years, an...

This article aims to analyze the constitutionality and legality of Ordinance 624 2019 Secretariat Penitentiary Administration State Ceará. The rule in question created a series obstacles rights prisoners, such as right visitation, intimate visitation not be placed isolation for more than 30 days, among others under justification helping “preserve security discipline within units”. constitutiona...
