Distributions of contact stresses at the neutral point in metal forming are very hard to be properly predicted due to the complex interface situation and lack of suitable friction models. In this paper, the dynamic friction model in which the friction depends on both time rate of strain and normal pressure has been applied to predict contact stresses in cylinder upsetting. Case studies have sho...

The 5-HT3 receptor, the only ionotropic 5-HT receptor, is expressed in limbic regions, including the hippocampus, amygdala, and cortex. However, it is not known whether it has a role in fear memory processes. Analysis of 5-HT3A receptor knockout mice in fear conditioning paradigms revealed that the 5-HT3A receptor is not required for the acquisition or retention of fear memory but is essential ...

Fear of falling (FOF) creates a psychological barrier to performing activities for many older adults. The negative impact of fear of falling increases risk of curtailment of activities, future falls, and injury. The specific aim for this study was to investigate the relationship between two fear of falling measures used in clinical research, the FOF Likert scale and Falls Self Efficacy Scale-In...

Introduction: Effective perception of fear signals is crucial for organism survival. When threated, the organism indicates defensive behaviors. Methods: Elevated plus–maze has high efficiency for measurement of fear behavior and is widly used for fear behavior determination. Increase in two parameters percent of openarm entries (%OAE) and percent of time spent in the open-arm (%OAT) in the ...
