In this issue of Neuron, Hultman et al. (2016) find that stress-induced abnormal social behavior reflects aberrant prefrontal regulation of downstream limbic networks. This illustrates how linking aberrant network dynamics to neuropsychiatric disorders may lead to new circuit-based therapeutic interventions.
Introduction: Clinical education is a complicated process which is affected by several factors and variables. Thus the aim of this study was to determine the stressing factors in clinical education from the viewpoints of students of Boushehr University of Medical Sciences. Methods: In this descriptive cross-sectional study, 334 students of Boushehr University of Medical Sciences were selected t...
Understanding the mechanical degradation of microelectronic solder joints under high electric current stressing is an important step to develop a damage mechanics model in order to predict the reliability of a solder joint under such loading. In this paper, the experiment results for flip chip solder joints under high current stressing are reported. Nanoindentation tests suggest that mechanical...
In this paper, Moir e interferometry technique is used to measure the in situ displacement evolution of lead-free solder joint under electric current stressing. Large deformation was observed in solder joint under high density (10 A/cm) current stressing. The deformation was found to be due to electromigration in the solder joint. An electromigration constitutive model is applied to simulate de...
In this paper, we present an empirical study of a recent spam campaign (a “stress test”) that resulted in a DoS attack on Bitcoin. The goal of our investigation being to understand the methods spammers used and impact on Bitcoin users. To this end, we used a clustering based method to detect spam transactions. We then validate the clustering results and generate a conservative estimate that 385...
Inhaled fibrous particles deposited in the lung periphery elicit a chronic inflammatory response that leads to production of fibrogenic mediators (1, 2). The fibrogenesis observed in asbestosis or silicosis, despite differences in histopathologic appearance, leads to similar disruptions in lung architecture, with deposition of extracellular matrix and cell proliferation characteristic of inters...
