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...

OBJECTIVE The present study investigated the influence of neuroticism (NEO Five-Factor Inventory (NEO-FFI)) and psychological symptoms (Brief Symptom Inventory (BSI)) on pleasure, arousal, and dominance (PAD) ratings of the International Affective Picture System (IAPS). METHODS The subjects (N=131) were presented with images from the IAPS (30 images) and new images (30 images). The influence ...

OBJECTIVE To examine the total and domain-specific prevalence of verbally and physically abusive, socially inappropriate, and care-resistive behaviors according to the Minimum Data Set (MDS) compared with research instruments in nursing home residents with severe dementia. DESIGN, SETTING, AND METHODS As part of a longitudinal observational study, MDS behavioral symptoms data were compared wi...

It is well established that the thickness of a hydrogel contact lens is a significant parameter both in terms of fitting (Mertz et al., 1979; Killpatrick, 1980) and oxygen transmissibility (Hill, 1975). It is acknowledged that the average thickness is clinically significant with respect to gas transmission and the edge thickness relates primarily to comfort and peripheral corneal anoxia. In pra...

BACKGROUND Clinical experience suggests that the work characteristics of staff in residential care may influence the well-being of residents with dementia. However, few studies have explored those anecdotal experiences. The aim of this study was to investigate associations between work characteristics of nursing staff and prevalence of behavioral symptoms among people with dementia in residenti...

Abstract Background Cancer diagnosis may cause deep emotional and affective problems in patients and their families.Nowadays, however, despite its rising prevalence,cancer is no longer synonymous with death. Given the significance of emotional well-being in cancer patients, we decided to assess the frequency of psychological problems in seven to seventeen yearolds with acute lymphoblastic leu...
