BACKGROUND AND OBJECTIVES The introduction of extracorporeal circulation in clinical practice was decisive for the development of modern cardiovascular surgery. Addition of new procedures and equipment, however, brings inherent risks and complications. The objective of this report is to describe a malfunction of the oxygenation system and emphasize the importance of the interaction among the me...

Chronic use of cocaine is associated with a reduced density of dopaminergic D2 receptors in the striatum, with negative consequences for cognitive control processes. Increasing evidence suggests that cognitive control is also affected in recreational cocaine consumers. This study aimed at linking these observations to dopaminergic malfunction by studying the spontaneous eyeblink rate (EBR), a m...

background and aim: vestibular migraine is a type of migraine that causes vertigo, dizziness, and imbalance in addition to typical migraine symptoms. in this study, we aimed to investigate vestibular system in these patients by videonystagmography (vng), electrocochleography (ecochg), and vestibular evoked myogenic potential (vemp) testing. methods: this empirical study was conducted on 10 pati...

in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...

Recently security researchers have started to look into automated generation of attack trees from socio-technical system models. The obvious next step in this trend of automated risk analysis is automating the selection of security controls to treat the detected threats. However, the existing socio-technical models are too abstract to represent all security controls recommended by practitioners...

In studying the performance of academic systems, one often tries to find out—by inspecting some well-defined parameters—how specific changes in legal system influence volume and quality desired outputs, such as publications, patents, or alumni. This mechanistic approach neglects fact that main actors this spectacle are not passive, but have their own priorities, actively self-organize response ...
