A new formalism to describe the spatiotemporal evolution of relativistic Raman backscatter ~RBS! of ultrashort laser pulses in underdense plasma has been developed. This theory is based on an eikonal representation for the RBS field and averaging over the oscillation frequency. Equations are derived for the evolution of the RBS radiation field amplitude and phase and for particle motion in the ...

From measurements over the last two years we have demonstrated that the charge collection system based on Faraday cups can robustly give near-1% absolute implantation fluence accuracy for our electrostatically scanned 200 kV Danfysik ion implanter, using four-point-probe mapping with a demonstrated accuracy of 2%, and accurate Rutherford backscattering spectrometry (RBS) of test implants from o...

Many heterologous genes when cloned into bacterial expression vectors are poorly expressed because of an inefficient ribosome binding site (RBS). We have constructed a plasmid which expresses human gamma-interferon (gamma-IF), where the level of expression is limited by the RBS. Expression was increased by placing the gamma-IF sequence immediately downstream of a small translated sequence. The ...

مکانیزم شکست ناشی از خزش در طی حادثه شدید یک رآکتور‌ آبی‌تحت‌فشار به‌جهت انتقال مواد رادیواکتیو به محیط‌زیست اهمیت ویژه‌ای برخوردار است. دنبال شدید، حرارت واپاشی منتقل‌شده سایر قسمت‌های سیستم‌خنک‌کننده رآکتور می‌تواند منجر گرم‌شدن سازه‌های سیستم خنک‌کننده (RCS) و خرابی نواحی تحت‌فشار آسیب‌پذیر شود. قطع‌کامل‌برق (SBO) بدون اقدامات اپراتور (توالی TMLB) یکی محتمل‌ترین سناریوهایی است که ممکن یکپارچ...

Sensor networks have emerged as an interesting and important research area in the last few years. These networks require that time be synchronized more precisely than in traditional Internet applications. In this paper, we compared and analyzed the performance of the RBS and TDP mechanisms in the view of the number of generated messages and the synchronization accuracy. The reason that we chose...

Background: Obesity is a global epidemic and is on the rise. Obesity is defined as a body mass index (BMI) which is equal to or more than 30kg/m 2 . It is one of the modifiable risk factors of type 2 diabetes. This study was undertaken to assess the relationship between BMI, WHR, RBS and BP. Method: This cross-sectional study included 776 apparently healthy adult individuals who met the inclusi...

Roberts syndrome/SC phocomelia (RBS) is an autosomal recessive disorder with growth retardation, craniofacial abnormalities and limb reduction. Cellular alterations in RBS include lack of cohesion at the heterochromatic regions around centromeres and the long arm of the Y chromosome, reduced growth capacity, and hypersensitivity to DNA damaging agents. RBS is caused by mutations in ESCO2, which...

The present study represents a replication and extension of the original Response Bias Scale (RBS) validation study. In addition to examining the relationship between the Test of Memory Malingering (TOMM), RBS, and several other well-researched Minnesota Multiphasic Personality Inventory 2 (MMPI-2) validity scales (i.e., F, Fb, Fp, and the Fake Bad Scale), the present study also included the re...

Utilizing the measured corneal birefringence from a data set of 150 eyes of 75 human subjects, an algorithm and related computer program, based on Müller-Stokes matrix calculus, were developed in MATLAB for assessing the influence of corneal birefringence on retinal birefringence scanning (RBS) and for converging upon an optical/mechanical design using wave plates ("wave-plate-enhanced RBS") th...

Influenza viral passaging through pre-vaccinated mice shows that emergent antigenic site mutations on the viral hemagglutinin (HA) impact host receptor-binding affinity and, therefore, the evolution of fitter influenza strains. To understand this phenomenon, we computed the Significant Interactions Network (SIN) for each residue and mapped the networks of antigenic site residues on a representa...
