This paper considers the two-stage flexible flowshop scheduling problem with availability constraints. We discuss the complexity and the approximability of the problem, and provide some approximation algorithms with finite and tight worst case performance bounds for some special cases of the problem.
Early growth response-2 (Egr-2) protein is a transcription factor, which belongs to Egr family which involve in modulating the peripheral immune response, by means of the induction of differentiation of lymphocyte precursors, activation of T and B cells. Egr-2 plays essential roles in peripheral nerve myelination, adipogenesis, tissue repair and fibrosis,… (More)
OBJECTIVE To investigate the effect of evoked heat shock protein 70 (HSP70) expression on the hearing function of the cochlea in guinea pigs. METHODS Guinea pigs were divided into pre-exposure group (pre-treated with white noise exposure at 100 dB SPL for 45 min) and none pre-exposure group. Auditory brainstem response (ABR) thresholds were recorded at… (More)
The transmission capacity of a wireless ad hoc network is defined as the maximum allowable spatial density of transmissions such that the outage probability does not exceed some specified threshold. This work studies the improvement in transmission capacity obtainable with successive interference cancellation (SIC), an important receiver technique that has… (More)
Drugs can influence the whole biological system by targeting interaction reactions. The existence of interactions between drugs and network reactions suggests a potential way to discover targets. The in silico prediction of potential interactions between drugs and target proteins is of core importance for the identification of new drugs or novel targets for… (More)
—Since the seminal work of Grossglauser and Tse , the two-hop relay algorithm and its variants have been attractive for mobile ad hoc networks (MANETs) due to their simplicity and efficiency. However, most literature assumed an infinite buffer size for each node, which is obviously not applicable to a realistic MANET. In this paper, we focus on the exact… (More)
