When aiming for large-scale parallel computing, waiting time due to network latency, synchronization, and load imbalance are the primary opponents of high efficiency. A common approach hide latency with computation is use non-blocking communication. In presence a consistent imbalance, synchronization cost just visible symptom imbalance. Tasking approaches as in OpenMP, TBB, OmpSs, or C++20 coro...

Performing two cognitively demanding tasks at the same time is known to decrease performance. The current study investigates the underlying executive functions of a dual-tasking situation involving the simultaneous performance of decision making under explicit risk and a working memory task. It is suggested that making a decision and performing a working memory task at the same time should part...

While much is known about the effects of dual tasking on cyclical and continuous motor performance (e.g., locomotion), there is a paucity of information on the effect of dual tasking on the initiation of movement. Therefore, the purpose of this study was to investigate the effect of a concurrent cognitive task on gait initiation in three groups: patients with Parkinson disease, healthy older ad...

We investigate the problem of large-scale mobile crowdtasking, where a large pool of citizen crowd-workers are used to perform a variety of location-specific urban logistics tasks. Current approaches to such mobile crowd-tasking are very decentralized: a crowd-tasking platform usually provides each worker a set of available tasks close to the worker’s current location; each worker then independ...

Adam is an experimental language derived from Ada. it was developed to facilitate study of issues in Ada implementation. The two primary objectives which motivated the development of Adam were. to program supervisory packages for multitask scheduling, and to formulate algorithms for compilation of Ada tasking. Adam Is a subset of the sequential program constructs of Ada combined with a set of p...

BACKGROUND Poor cerebral perfusion may contribute to cognitive impairment in type 2 diabetes mellitus (T2DM). We conducted a randomized controlled trial to test the hypothesis that resveratrol can enhance cerebral vasodilator function and thereby alleviate the cognitive deficits in T2DM. We have already reported that acute resveratrol consumption improved cerebrovascular responsiveness (CVR) to...

This paper analyzes the impact of wage comparisons among inequity-averse agents on optimal incentive intensities in a linear–exponential–normal moral hazard model with multi-tasking. We consider individual and team production tasks that differ in that only individual production causes wage inequality. If the tasks are substitutes in the agents’ effort cost functions, the principal might want to...

According to traditional conceptualizations of the relationship between fear of falling and falls in older adults, fear of falling is considered to be predictive of falls because it leads to activity avoidance which, in turn, leads to de-conditioning that increases fall risk. The recent literature has begun to challenge such conceptualizations. Specifically, it has been argued that fear of fall...

The title furan-ocoumarin, C14H12O4 [systematic name: 9-hy-droxy-2-(prop-1-en-2-yl)-2,3-di-hydro-7H-furo[3,2-g]chromen-7-one], crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ essentially in the orientation of the propenyl group with respect to the mean plane of the furan-ocoumarin moiety; the O-C(H)-C=C torsion angle is 122.2 (7)° in mol-...
