Context-awareness is highly desired, particularly in highly dynamic mobile environments. Semantic Web Services (SWS) address context-adaptation by enabling the automatic discovery of distributed Web services based on comprehensive semantic capability descriptions. Even though the appropriateness of resources in mobile settings is strongly dependent on the current situation, SWS technology does ...

This paper describes a conceptual model investigating the impact of organizational social web site (SWS) usage on individual performance. Previous research on SWS usage offers rather lean measures, which do not account for the context (i.e. the task the system is used for). We address this research gap by constructing a very rich usage measure and introducing it in the context of organizational...

Objective The current study aimed to investigate the differences in sleep reactivity and effort differs among late night shift workers (LSWs) non-late (non-LSWs), non-shift (non-SWs).Methods In total, 6,023 participants (1,613 non-SWs, 3,339 LSWs, 1,071 non-LSWs) were recruited. Non-SWs was defined as those who works at fixed schedules during standard daylight. LSWs work hours (10 <sub>PM...

Mutations in Drosophila Swiss cheese (SWS) or its vertebrate orthologue neuropathy target esterase (NTE), respectively, cause progressive neuronal degeneration in Drosophila and mice and a complex syndrome in humans that includes mental retardation, spastic paraplegia and blindness. SWS and NTE are widely expressed in neurons but can also be found in glia; however, their function in glia has, u...

To evaluate the diagnostic performance of a new technique of shear wave speed (SWS) imaging for the diagnosis of thyroid nodule with elasticity modulus and SWS measurement. 322 thyroid nodules in 322 patients (216 benign nodules, 106 malignant nodules) were included in this study. All the nodules received conventional ultrasound (US) and SWS imaging (Aplio500, Toshiba Medical Systems, Japan) be...

To evaluate the associated factors leading to misdiagnosis with VTIQ for differentiation between benign from malignant thyroid nodules (TNs). The study included 238 benign TNs and 150 malignant TNs. Conventional ultrasound (US) features and VTIQ parameters were obtained and compared with the reference standard of histopathological and/or cytological results. Binary logistic regression analysis ...

Slow waves (SWs, 0.5-4Hz) in field potentials during sleep reflect synchronized alternations between bursts of action potentials and periods of membrane hyperpolarization of cortical neurons. SWs decline during sleep and this is thought to be related to a reduction of synaptic strength in cortical networks and to be central to sleep's role in maintaining brain function. A central assumption in ...

Concerns remain regarding the heterogeneity in overlapping human immunodeficiency virus (HIV) risk behaviors among sex workers (SWs) in Pakistan; specifically, the degree to which SWs interact with people who inject drugs (PWID) through sex and/or needle sharing.Following an in-depth mapping performed in 2011 to determine the size and distribution of key populations at highest risk of HIV acqui...

BACKGROUND self-neglect (SN) is a global health and social problem affecting societies, which is largely hidden, under-reported and underresearched. Community nurses (CNs) and social workers (SWs) need to be knowledgeable about SN. OBJECTIVE to determine CNs and SWs sources and level of SN knowledge. METHODS quantitative, descriptive and cross-sectional. SUBJECTS CNs and SWs working in th...

When invertebrate rhodopsins were used as the outgroup, the rooted phylogenetic tree of 26 vertebrate visual pigments (VPs) was constructed. These VPs are distinguished into the following four clusters: (1) RH1 cluster consisting of rhodopsins, (2) RH2 cluster consisting of VPs with variable ranges of absorption spectra, (3) SWS cluster of short wavelength-sensitive VPs, and (4) LWS/MSW cluster...
