The possibility to enhance the detection efficiency of the Concealed Information Test (CIT) by increasing executive load was investigated, using an interference design. After learning and executing a mock crime scenario, subjects underwent three deception detection tests: an RT-based CIT, an RT-based CIT plus a concurrent memory task (CITMem), and an RT-based CIT plus a concurrent set-shifting ...

INTRODUCTION Rule induction tests such as the Wisconsin Card Sorting Test require executive control processes, but also the learning and memorization of simple stimulus-response rules. In this study, we examined the contribution of diminished learning and memorization of simple rules to complex rule induction test performance in patients with amnestic mild cognitive impairment (aMCI) or Alzheim...

Reconstructing regulatory and signaling response networks is one of the major goals of systems biology. While several successful methods have been suggested for this task, some integrating large and diverse datasets, these methods have so far been applied to reconstruct a single response network at a time, even when studying and modeling related conditions. To improve network reconstruction we ...

In this paper, we present a performance study on three diierent load balancing algorithms. The rst algorithm employs only task assignment, whereas the other two allow both task assignment and migration. We conclude that although task migration usually costs more than task assignment, under some situations it can augment task assignment to provide extra performance improvement. This is because t...

The deregulation of the European energy market, combined with emerging advanced capabilities of information technology, provides strategic opportunities for new knowledge-oriented services on the power grid. HOMEBOTS is the name we have coined for one of these innovative services: decentralized power load management at the customer side, automatically carried out by a ‘society’ of interactive h...

Task migration is an eeective strategy to achieve load balancing and high resource utilization in a meta-computing environment. In this paper, we argue that traditional task migration methods take into account only the computation, and neglect any necessary data migration. Accordingly, we introduce a new deenition of a task, propose a novel dynamic task migration scheme, and evaluate this schem...

Early experiments in migrating task images from one node in a metacomputing environment to another have shown, that it is possible to achieve almost maximum data throughput in LAN networks. With WAN-connected metacomputers however, the time spent in the task migration is not negligible. Here, alternative routing paths must be used concurrently to reduce the total migration time. We present a pr...
