Alcohol overconsumption is a major cause of preventable mental disorders and death in the United States around world. The pathogenesis alcohol dependence, abuse, toxicity to central nervous system remains incompletely understood. Cell culture-based models have been highly valuable studying molecular cellular mechanisms underlying contribution individual CNS cell types ethanol’s effects on brain...

background many industrial devices have an excessive vibration which can affect human body systems. the effect of vibration on cochlear histology has been as a debatable problem in occupational health and medicine. objectives due to limitation present in human studies, the research was conducted to survey the influence of vibration on cochlear histology in an animal model. materials and methods...

In this paper, we analyze a distributed amplifier based on input/output attenuation compensation. The analysis is carried out for a HEMT transistor; and a constant-k section filter is used to calculate the amplifier’s characteristics such as attenuation factor, phase constant and gain. The proposed design approach enables us to examine the tradeoff among the variables, which include the type an...

During leaf development, a decrease in cell number often triggers an increase in cell size. This phenomenon, called compensation, suggests that some system coordinates cell proliferation and cell expansion, but how this is mediated at the molecular level is still unclear. The fugu2 mutants in Arabidopsis (Arabidopsis thaliana) exhibit typical compensation phenotypes. Here, we report that the FU...

In this paper the problem of flow control in fast, connection oriented communication networks supporting traffic generated by multiple sources is considered. The network is modelled as a dynamic system with different delay times. A nonlinear strategy governing the behaviour of the sources is proposed. The strategy combines Smith principle and feed-forward compensation with the conventional rela...

We demonstrate that the conditions of spaser generation and the full loss compensation in a dense resonant plasmonic-gain medium (metamaterial) are identical. Consequently, attempting the full compensation or overcompensation of losses by gain will lead to instability and a transition to a spaser state. This will limit (clamp) the inversion and lead to the limitation on the maximum loss compens...

We examine the effect of a Danish reform in 2002 that increased compensation for permanent loss of earnings capacity and extended the period when whiplash claimants could get compensation for temporary loss of earnings. The first is subject to extensive state verification by the government while the second is not. Using weekly data about disability, drug purchases and use of health services dur...

An active metal strip hybrid plasmonic waveguide (MSHPW) using gain materials as loss compensation is proposed with an extremely simple fabrication procedure. Gain materials are introduced either in the low-index layer or in the high-index layer of MSHPW. The effects of waveguide dimensions and material gain coefficients on loss compensation are analyzed at the communication wavelength. For one...
