-Cloud computing, as a new model of service provision in distributed computing environment, faces the great challenge of energy consumption because of its large demand for computing resources. Choosing improper scheduling method to execute cloud workflow tends to result in the waste of power consumption. In order to lower the higher power consumption for cloud workflow executing, we propose a p...

Technology scaling and manufacturing process affect the performance of digital circuits, making them more vulnerable to environmental influences. Some defects are shown as delay faults therefore their testing is very important, mainly path delay faults. Such faults are tested over critical paths which have to be specified in a digital circuit. A problem of the critical paths selection is discus...

Multi-processor scheduling is an NP-hard problem, so heuristic solutions must be found. Several critical path heuristics have been proposed, but these must be empirically tested to see if their solutions are adequate. This paper examines the performance of four critical path heuristics and nds that they are unable to perform well on the types of graphs which are likely to be created by compiler...

In this paper, we focus on the problem of secure multicast in dynamic groups. In this problem, a group of users communicate using a shared group key. Due to the dynamic nature of these groups, to preserve secrecy, it is necessary to change the group key whenever the group membership changes. While the group key is being changed, the group communication needs to be interrupted until the rekeying...

Metastasis means the dissemination of the cancer cells from one organ to another which is not directly connected to the primary site. Metastasis has a crucial role in the prognosis of cancer patients. A few theories, different types of cell and several molecular pathways have been proposed to explain the mechanism of metastasis. In this work, the related articles in the limited period of time, ...

Background: Toll-like receptors (TLRs) detect diverse pathogen-associated molecular patterns and play a critical role in the innate immune response. Hosts should activate TLR-signaling pathways to eliminate invading pathogens. However, excessive activation of these pathways may interrupt immune homeostasis, leading to several diseases. Therefore precise regulation of TLR-signaling pathways is e...
