We examine limitations of carrier removal with a p-n junction in Raman devices, namely, ineffectiveness at high optical intensities due to the applied field being screened, electrical heat dissipation, and the possibility of thermal instability. © 2006 Optical Society of America OCIS codes: (130.3120) Integrated optics devices, (190.4390) Nonlinear optics, integrated

We present a preprocessing algorithm for SAT, based on the HypBinRes inference rule, and show that it does not improve the performance of a DPLL-based SAT solver with conflict recording. We also present evidence that the ineffectiveness of the preprocessing algorithm is the result of interaction with the branching heuristic used by the solver.

Information Technology Governance is currently widely implemented in companies. One of the domains that can be concern risk management. The application TKTI this domain help companies identify, evaluate, reduce, and manage risks related to their business achieve company goals better. In case, three frameworks considered, including NIST, ISO 27001, Octave, but implementing these only sometimes g...

Mycobacterium tuberculosis (MTB) continues to plague humanity because of significant gaps in our understanding of MTB infection, including the nature of a protective versus pathological host response, why antimicrobial cure is so difficult, and the ineffectiveness of vaccination. The development of a zebrafish model, utilizing infection with the natural fish pathogen Mycobacterium marinum (Mm),...

background patient’s rights are worldwide considerations. saudi patient’s bill of rights (pbr) which was established in 2006 contained 12 items. lack of knowledge regarding the saudi pbr limits its implementation in health facilities. this study aimed to investigate the knowledge of health professions’ students at college of applied medical sciences (cams) riyadh saudi arabia regarding the exis...

Differential pulse polarography study was used to investigate the influence of glutathion on cis- and trans-DDP induced alterations of DNA structure. Though the applied concentration of glutathion has no effect on the reaction on DNA with cis-DDP, it greatly modifies the reaction with trans isomer. This may be an important reason for the ineffectiveness of the trans-DDP as an antitumor drug.

BACKGROUND Issues of personal control have been proposed to play a central role in the aetiology and maintenance of eating disorders. Empirical evidence supporting this relationship is inconsistent, partly due to the multiplicity of constructs used to define "control". This study compares six commonly used measures of control with the aim of determining which operationalisation of control is mo...

BACKGROUND Patient's rights are worldwide considerations. Saudi Patient's Bill of Rights (PBR) which was established in 2006 contained 12 items. Lack of knowledge regarding the Saudi PBR limits its implementation in health facilities. This study aimed to investigate the knowledge of health professions' students at College of Applied Medical Sciences (CAMS) Riyadh Saudi Arabia regarding the exis...

In the treatment of primary hypothyroidism, guidelines issued by some organizations advise merely normalizing the TSH, reducing it to any value within the reference range. However, many studies show that this approach often produces little improvement in symptoms or in the risk of diseases associated with hypothyroidism. For this reason, some organizations and experts recommend titrating T4 dos...

BACKGROUND AND PURPOSE To evaluate the effect of prism adaptation (PA) on spatial neglect signs. METHODS Ten patients (hemianopia in 6) and 8 control subjects were included. Tasks were reading single words, nonwords, and a text, bell cancellation, line bisection, and scene drawing, before and after adaptation, with either deviating or neutral prisms. RESULTS Errors were more frequent in pat...
