as a major consequence of medical interventions, quality of life (qol) is of great importance for patients suffering from refractory diseases, particularly cancer. the unbiased measurement of changes in qol is thus crucial in such cases. a prevalent bias related to qol research is the ‘response shift’ (rs) phenomenon. this review article aims to define rs and the challenges in measuring it. in ...

Winter soil respiration (Rs) is becoming a significant component of annual carbon budgets with more warming in winter than summer. However, little is known about the controlling mechanisms of winter Rs in dryland. We made continuous measurements of Rs in four microsites (non-crust (BS), lichen (LC), moss (MC), and a mixture of moss and lichen (ML)) in a desert shrub-land ecosystem northern Chin...

In vitro gas production was measured to investigate associative effects of untreated and chemically treated rice straw (RS) and of RS and grass hay or mulberry leaves (ML). The RS was treated with NaOH, urea, or (NH4)HCO3. Cumulative gas production was recorded at 2, 4, 6, 8, 12, 16, 24, 36, 48, 60, 72, and 96 h of incubation, and the Gompertz function was used to describe the kinetics of gas p...

BACKGROUND Allergic rhinitis (AR) and rhinosinusitis (RS) negatively impact psychological well-being and health-related quality of life (HRQoL). However, few population-based studies have investigated the effects of these conditions on mental health and HRQoL. PURPOSE To explore independent associations of AR and/or RS with mental health and HRQoL using data from the 2013-2015 Korea National ...

This paper investigates the impact of relay selection (RS) on the performance of cooperative non-orthogonal multiple access (NOMA), where relays are capable of working in either full-duplex (FD) or half-duplex (HD) mode. A number of relays (i.e., K relays) are uniformly distributed within the disc. A pair of RS schemes are considered insightfully: 1) Single-stage RS (SRS) scheme; and 2) Two-sta...

RÉSUMÉ. Dans cet article, nous présentons une méthode de traduction automatique de termes biomédicaux. Cette méthode s’appuie sur une technique originale d’apprentissage supervisé de règles de réécriture et sur l’utilisation de modèles de langue. Les évaluations présentées montrent que notre technique est très performante et permet de traduire à partir et à destination de n’importe quelle langu...

Repetition of the same stimulus leads to a reduction in neural activity known as repetition suppression (RS). In functional magnetic resonance imaging (fMRI), RS is found for multiple object categories. One proposal is that RS reflects locally based "within-region" changes, such as neural fatigue. Thus, if a given region shows RS across changes in stimulus size or view, then it is inferred to h...

In the hippocampus, interneurons provide synaptic inhibition via the transmitter GABA, which can activate GABA(A) and GABA(B) receptors (GABA(A)Rs and GABA(B)Rs). Generally, however, GABA released by a single interneuron activates only GABA(A)Rs on its targets, despite the abundance of GABA(B)RS. Here, I show that during hippocampal rhythmic activity, simultaneous release of GABA from several i...
