The s-process takes place in stellar environments with temperatures between 8 to 100 keV. In such a plasma the nuclei follow a Maxwell-Boltzmann distribution. Reactions between nucei are characterized by a reaction rate that depends on the temperature of the stellar environment. Reaction rates based on experimental cross sections 〈σv〉 lab do not account for the thermal excitation of the nuclei....

1. Introduction The cerebral representation of pain perception in humans is poorly understood compared with that of other sensations such as touch or vibration. This is mainly because of a lack of appropriate instrumentation for stimulation and recording [1]. To our knowledge, only a few systematic studies of somatosensory evoked magnetic field (SEF) following painful stimulation (pain-related ...

Data interchange in the form of a standard exchange format(SEF) is only a first step towards tool interoperability. Inter-tool communication using files is slow and cumbersome; a better approach would be an application program interface, or API, that allowed tools to communicate with each other directly. This paper argues such an AP is a logical next step that builds on the current drive toward...

background: considering the physical, emotional and psychological complications of early or delayed menopause on women`s life, it is necessary to determine associated factors of menopause age. this study designed to determine menopausal age and associated factors in women of gorgan, i.e. the capital of golestan province in the north-east of iran.   methods: in this cross-sectional study, 804 me...

background: the main objective of this study was to assess the malnutrition and some socio-economic related factors based on three ethnic groups among primary school children in north of iran in 2010 . methods: this cross-sectional study was carried out through multistage cluster random sampling on 5698 subjects (2505 fars-native, 2154 turkman, and 1039 sistani) in 112 schools. well-trained sta...

The latency and variability of latency of single-unit responses to identical visual stimulation were measured in the frontal eye field (FEF), supplementary eye field (SEF), and anterior cingulate cortex (ACC) of macaque monkeys performing visually guided saccades. The mean visual response latency was significantly shorter in FEF (64 ms) than in SEF (81 ms) or ACC (100 ms), and latency values de...

Within the medial frontal cortex, the supplementary eye field (SEF), supplementary motor area (SMA), and pre-SMA have been implicated in the control of voluntary action, especially during motor sequences or tasks involving rapid choices between competing response plans. However, the precise roles of these areas remain controversial. Here, we study two extremely rare patients with microlesions o...

The supplementary eye field (SEF) is a region within medial frontal cortex that integrates complex visuospatial information and controls eye-head gaze shifts. Here, we test if the SEF encodes desired gaze directions in a simple retinal (eye-centered) frame, such as the superior colliculus, or in some other, more complex frame. We electrically stimulated 55 SEF sites in two head-unrestrained mon...

BACKGROUND The acquisition of a modern lifestyle may explain variations in asthma prevalence between urban and rural areas in developing countries. However, the effects of lifestyle on asthma have been investigated as individual factors with little consideration given to the effects of lifestyle as a set of attributes. The aim of the present study was to identify modern lifestyle domains and as...

Socioeconomic position (SEP) can be an important determinant for health. It can be assessed by different measures that look at factors such as occupation, education, income, living standards or area of residence—none of which capture the full picture. Our lead article compares the performance of five measures in predicting health outcomes, concluding that NZiDep (an individual-level index of so...
