Background: The aim of this study was to investigate psychosocial variables associated with frailty status. Moreover, gender differences in the psychosocial variables associated with frailty were examined. Methods: This cross-sectional study examined a community-dwelling sample of N = 210 older adults (M = 75.31 years). Frailty was measured with the Tilburg Frailty Indicator. Quality of life, d...

In this work, we implement the floating base prioritized whole-body compliant control framework described in Sentis et al. (IEEE Transactions on Robotics 26(3):483– 501, 2010) on a wheeled humanoid robot maneuvering in sloped terrains. We then test it for a variety of compliant whole-body behaviors including balance and kinesthetic mobility on irregular terrain, and Cartesian hand position trac...

This paper investigates the optimization of transmission spatial layer selection with unreliable rank indicator (RI) in downlink LTE systems. Taking the block error rate (BLER) into consideration, we propose an accurate throughput calculation (ATC) algorithm at user equipment (UE) side as well as at evolved NodeB (eNB) side. On the basis of ATC algorithm, we propose an accurate RI selection alg...

Powders of MoSi 2 containing ErzMo3Si 4 and Er203 particles were produced by ball milling arc-melted buttons of MoSi 2 containing 20 vol.% Er2Mo3Si 4. Two composites with grain diameters of 9 and 16/zm were produced by hot pressing the powders to 98% of theoretical density at 1565 °C and 1650 °C respectively. Some evidence of mechanical alloying was observed, but the majority of the Er2Mo3Si 4 ...

A series of tensile testing was carried out on the ultrafine grained 5083 Al alloy, which was fabricated by equal channel angular pressing (ECAP) with different ECAP strains, at low temperature superplastic (LTS) temperature of 548K. This investigation was aimed at examining the effect of the ECAP strain inducing different microstructure in the alloy on the deformation mechanisms at LTS regime....

With climate change and a burgeoning future world population there will be an increased need to reuse treated wastewater for a variety of uses including domestic water supplies as a water conservation measure. While there are technologies for partial treatment for the reuse of wastewater, in some areas of the world there is presently unregulated reuse of wastewater for agricultural irrigation a...

Abundance analysis of the cool extreme helium (EHe) star LSS 3378 is presented. The abundance analysis is done using LTE line formation and LTE model atmospheres constructed for EHe stars. The atmosphere of LSS 3378 shows evidence of H-burning, He-burning, and sprocess nucleosynthesis. The derived abundances of iron-peak and α-elements indicate absence of selective fractionation or any other pr...

Abstract Aims: The study goals were to determine the relationship between faecal indicator bacteria (FIB), the HF183 marker and land use, and the phylogenetic diversity of HF183 marker sequences in a tropical urban watershed. Methods and Results: Total coliforms, Escherichia co...

Existing software transactional memory (STM) implementations often exhibit poor scalability, usually because of nonscalable mechanisms for read sharing, transactional consistency, and privatization; some STMs also have nonscalable centralized commit mechanisms. We describe novel techniques to eliminate bottlenecks from all of these mechanisms, and present SkySTM, which employs these techniques....

In situ measurements of ozone (O3), carbon monoxide (CO) and meteorological parameters were made from December 2007 to November 2009 at the Xianggelila Regional Atmosphere Background Station (28.006 N, 99.726 E; 3580 m a.s.l.), southwest China. It was found that both O3 and CO peaked in spring while the minima of O3 and CO occurred in summer and winter, respectively. A normalized indicator (mar...
