BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is an uncommon pathology characterized by the acute onset of headache, vomiting, altered consciousness, seizures and focal neurological deficits. It was initially described in the setting of hypertension, uremia and immunosuppression. In the last decade there have been emerging reports of PRES in patients with advanced human immunod...

 Many efficient interior-point methods (IPMs) are based on the use of a self-concordant barrier function for the domain of the problem that has to be solved. Recently, a wide class of new barrier functions has been introduced in which the functions are not self-concordant, but despite this fact give rise to efficient IPMs. Here, we introduce the notion of locally self-concordant barrier functio...

in this research work, alpha particle detector is made using semi-insulating gaas. a surface barrier detector with a semi-insulating gaas substrate at room temperature with pressure of 10-4 torr under -particle radiation with 5.48 mev of am241 source, have been under investigation. energy resolution of 2 and 3 mm schottky diameter have been matured and compared with the effect of voltage varia...

background: coordination is a critical factor in successful organization and appropriate response to disasters. in this regard, a centralized coordination mechanism is the first step towards an effective, efficient, and sustainable response in order to be ensured of the short- and long-term recovery. thus, this study aimed to identify and prioritize the barriers and facilitators of coordination...

Learning Communities is one approach in individuals to improve their skills and knowledge. Web based learning communities provide additional capabilities such as global distribution of participants and asynchronous participation. The learning process in such communities is flexible and distributed, but still uni-directional: knowledge, advices and support is transferred from professors to stude...
