Mechanisms of attention are required to prioritise goal-relevant sensory events under conditions of stimulus competition. According to the perceptual load model of attention, the extent to which task-irrelevant inputs are processed is determined by the relative demands of discriminating the target: the more perceptually demanding the target task, the less unattended stimuli will be processed. A...

hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. cardiac involvement is very rare, especially when there is not hepatic involvement. we describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to rajaei heart center, tehran, iran in 2012. her chest computed tomographic scan showed a cardiac mass. echocardiographic examination...

a r t i c l e i n f o The involvement of working memory capacity (WMC) in ruled-based cognitive skill acquisition is well-established, but the duration of its involvement and its role in learning strategy selection are less certain. Participants (N = 610) learned four logic rules, their corresponding symbols, or logic gates, and the appropriate input–output combinations in three-gate circuit pa...

this article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of english as a foreign language (efl). the study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was aff...

Lavie's theory of attention proposes that the processing load in a relevant task determines the extent to which irrelevant distractors are processed. This theory was tested by asking participants in a study to perform linguistic tasks of low or high load while ignoring irrelevant visual motion in the periphery of the display. Although task and distractor were unrelated, both functional imaging ...

The present study investigated whether participants can develop temporal preparation driven by auditory isochronous rhythms when concurrently performing an auditory working memory (WM) task. In Experiment 1, participants had to respond to an auditory target presented after a regular or an irregular sequence of auditory stimuli while concurrently performing a Sternberg-type WM task. Results show...

In this paper, we present a load-balancing strategy (Adaptive Load Balancing strategy) for data parallel applications to balance the work load effectively on a distributed system. We study its impact on computation-hungry matrix multiplication application. The ALB strategy enhances the performance with features such as intelligent node selection, pre-task assignment, adaptive task sizing and bu...

Age-related decline in executive functions and postural control due to degenerative processes in the central nervous system have been related to increased fall-risk in old age. Many studies have shown cognitive-postural dual-task interference in old adults, but research on the role of specific executive functions in this context has just begun. In this study, we addressed the question whether p...

{ We nd two interesting thresholds for the number of tasks generated under a new model of on-line task assignment and load balancing environment, in which tasks are assigned without any information on current load status, and load balancing is achieved together with task assignment. It is shown that balanced task assignment can be obtained deterministically when the number of tasks exceeds the ...

In this paper, a List Simulated Anneal (LSA) algorithm is proposed for the DAG tasks scheduling on the Network-on-chip to simultaneously optimize makespan, load balance and average link load. A task list is first created for the DAG tasks, and the task-to-processor assignment is performed using Best Fit rule. Then the generated schedule is further optimized using LSA. In LSA, the task execution...
