We report on a data-parallel classical molecular dynamics algorithm and its implementation on Connection Machines CM-5 and CM-200 using CM-Fortran, a Fortran-90 dialect. A grid-based spatial decomposition of the atomic system is used for parallelization. Our previous algorithm on the CM's calculated all forces in the nearby region. A diierent algorithm using classical Verlet neighbor lists is m...

Antipruritic effects of 70% ethanol extract (CM-ext) of Cnidii Monnieri Fructus (dried fruits of Cnidium monnieri CUSSON, Umberifferae) were investigated. In mice, an oral administration of CM-ext (200 and 500 mg/kg) inhibited compound 48/80-induced scratching behavior without influence on spontaneous locomotion. Isopimpinellin (3) and osthol (1), coumarin derivatives isolated from CM-ext, show...

CMN projected adult size categories: small (<1.5 cm); medium (M1: 1.5-10 cm, M2: >10-20 cm); large (L1: >20-30 cm, L2: >30-40 cm); and giant (G1: >40-60 cm, G2: >60 cm) Total number of naevi in the first year of life: 0, 1 to 20, 21 to 50, 51 or more Additional descriptors of CMN: localization, colour heterogeneity, surface rugosity, hypertrichosis (all none, moderate, marked), presence of nodu...

During the past years, pharmaceutical counterfeiting was mainly a problem of developing countries with weak enforcement and inspection programs. However, Europe and North America are more and more confronted with the counterfeiting problem. During this study, 26 counterfeits and imitations of Viagra® tablets and 8 genuine tablets of Viagra® were analysed by Raman microspectroscopy imaging. Afte...

BACKGROUND AND PURPOSE Lower-pole ureteronephroscopy requires transmission of holmium:YAG energy along a deflected fiber. Current ureteroscopes are capable of high degrees of deflection, which may stress laser fibers beyond safe limits during lower-pole use. We hypothesized that optical fiber and safety measures differ among manufacturers. MATERIALS AND METHODS Small (200-273-microm) and medi...

Determining fuel areal density (ρR) in moderate-ρR (100-200 mg/cm 2) cryogenic DT implosions is challenging as it requires new spectrometry techniques and analysis methods to be developed. In this paper, we describe a new method for analyzing the spectrum of knock-on deuterons (KO-D), elastically scattered by primary DT neutrons, from which a fuel ρR can be inferred for values up to ~200 mg/cm ...

Fluorescence excitation and emission spectra of the 81 and 82 states of model trienes and tetraenes are measured in free jet expansions. The barriers to cis-trans isomerization in the 81 state are <200 cm-1 for trienes and -2000 cm-1 for tetraenes. <250 fs nonradiative decay of ' the 82 state of tetraenes is deduced from the observed Lorentzian linewidths.

An antimicrobial-surface kinetic test which maximizes probability of cell-to-surface contact has been developed. The measurement of rate of kill by a nonleaching antimicrobial surface is based on the number of surviving bacterial cells at specific times of exposure to various amounts of total treated surface area of test substrate. This method gives information for direct comparison of rate of ...
