Streptococcus pyogenes isolates obtained in 1981 to 1997 from patients and healthy subjects were characterized by pulsed-field gel electrophoresis (PFGE) patterns, biotyping, and the presence of spe genes encoding streptococcal pyrogenic exotoxins. Changes in the profiles were shown in the serotype M1/T1 isolates from pharyngitis over this period, but not in serotype M3/T3 isolates. The charact...
SYNOPSIS Thin spray-on liners (TSLs) have been used as sealants and rock support in tunnels for over 25 years. Laboratory tests indicated satisfactory properties that can provide adequate strength, adhesion, toughness, elasticity part of systems mining excavations. These characteristics are, however, not always demonstrated practice, when mine environmental conditions do correspond with laborat...
The present work addresses two key issues relating to the study of rate effects in adhesively bonded joints. Firstly, accurate determination crack tip strain and secondly cohesive zone length. rate-dependent fracture behaviour adhesive joints with either a toughened epoxy or ductile polyurethane was investigated under mode I loading rates ranging from 0.1 mm/min 1.0 m/s digital image correlatio...
Several thermal-therapy strategies such as thermal ablation, hyperthermia-triggered drug delivery from temperature-sensitive liposomes (TSLs), and combinations of the above were investigated in a rhabdomyosarcoma rat tumor model (n = 113). Magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) was used as a noninvasive heating device with precise temperature control for image-gui...
One possible reason of the inconsistent results of linkage analyses of schizophrenia, a complex disorder, was mainly due to the small sample size of studies. This Taiwan Schizophrenia Linkage Study (TSLS) was designed to collect a large family sample with at least two affected siblings of a single ethnicity. The 17.6 millions of Taiwanese Chinese, age over 15, was the sample population, and 78 ...
The topological electronic structure of a single twin boundary and coherent twinning superlattices (TSLs) based on the SnTe class materials is calculated discussed within supercell implementation. consist two planes (TPs) in arranged such way that each boundaries forms mirror plane for entire structure. Two types TP boundary, cationic anionic, can exist, so three supercells be constructed. We s...
The linear coefficient in a partially model with confounding variables can be estimated using double machine learning (DML). However, this DML estimator has two-stage least squares (TSLS) interpretation and may produce overly wide confidence intervals. To address issue, we propose regularization selection scheme, regsDML, which leads to narrower It selects either the TSLS or regularization-only...
Pulsed-neutron die-away (PNDA) experiments can be useful benchmarks to validate neutron thermal scattering laws (TSLs). The experiment uses a generator impinge short (∼10 −4 s), mono-energetic pulse on target sample. After the pulse, population within sample moderates and reaches equilibrium with fundamental spatial mode characteristic decay-time eigenvalue. eigenvalue extracted from experiment...
Streptococcus pyogenes strains producing pyrogenic exotoxin A (scarlet fever toxin) have recently caused episodes of streptococcal toxic-shock-like syndrome (TSLS). We exploited knowledge of genetic diversity and relationships among exotoxin A-producing patient strains provided by multilocus enzyme electrophoresis to select strains for comparative sequencing of toxin genes. Our analysis identif...
