A hallmark of flexible behavior is the brain's ability to dynamically adjust speed and accuracy in decision-making. Recent studies suggested that such adjustments modulate not only the decision threshold, but also the rate of evidence accumulation. However, the underlying neuronal-level mechanism of the rate change remains unclear. In this work, using a spiking neural network model of perceptua...

We present a combinatorial coverage measurement analysis for (subsets) of the TLS cipher suite registries by analyzing the specified ciphers of IANA, ENISA, BSI, Mozilla and NSA Suite B. The method introduced here may contribute towards the design of quality measures of cipher suites, and may also be applied more broadly to the analysis of configurable systems. Keywords—Combinatorial testing, c...

This study identified the possible threshold to predict dengue fever (DF) outbreaks using Baidu Search Index (BSI). Time-series classification and regression tree models based on BSI were used to develop a predictive model for DF outbreak in Guangzhou and Zhongshan, China. In the regression tree models, the mean autochthonous DF incidence rate increased approximately 30-fold in Guangzhou when t...

conclusions the dental health status of hiv-positive patients in this region was almost inappropriate. most social, behavioral, and medical factors had no influence on dental health; only a correlation between dental health, age, and duration of hiv involvement was observed. results the mean value of dmft index was 11.87 ± 8.08, where the mean values of decayed and missing teeth were 8.42 ± 5.4...

BACKGROUND High prevalence rates of psychological distress in medical training and later professional life indicate a need for prevention. Different types of intervention were shown to have good effects, but little is known about the relative efficacy of different types of stress management interventions, and methodological limitations have been reported. In order to overcome some of these limi...

progressive cognitive decline is one of the hallmark symptoms of alzheimer’s disease (ad) which can be modeled by β-amyloid injection into specific regions of brain. since epigallocatechin-3-gallate (egcg) is a potent antioxidant agent which its role against oxidative stress and inflammation has been shown in prior studies, we tried to determine whether egcg administration protects against β-am...

Stress may cause special behavioral and biochemical changes. Kindling is presumed to be the underlying mechanism for such changes. Lamotrigin, an anti-kindling agent which blocks glutamate release through inhibiting sodium channels may reverse these behavioral changes. The aim of this study was to explore the effects of lamotrigin in management of behavioral and biochemical changes caused by st...
