Specifically, this paper proposes a methodology for calculating the maximum network throughput of multiple transmission tasks under storage and delay constraints over a space network. A mixed-integer linear programming (MILP) is formulated to solve this problem. Simula- tions results show that the proposed methodology can successfully calculate the optimal throughput of a space network under storage and delay constraints, as well as a clear, monotonic relationship between end-to-end delay and the maximum network throughput under storage constraints. At the same time, the optimization re- sults shine light on the routing and transport protocol design in space communication, which can be used to obtain the optimal network throughput.展开更多

Based on the charac- teristics of multi-code CDMA technology, the scheme factitiously improves the transmission bit rate of a terminal by compressing the packet transmission time and thereby increases the number of the orthogonal spreading codes used by the terminal. By this means, the average interference level of the system is reduced and the system capacity is improved. Simulation results show that the proposed scheme exhibits larger throughput compared with the traditional multi-code CDMA slotted Aloha systems.展开更多

These direct interactions with molecular targets may trigger a series of downstream effects on metabolic-biochemical and regulatory-signaling networks that can invoke cellular consequences leading to adaptive homeostatic or adverse pathological responses. Regulators for drug and chemicals safety have therefore since long required the testing of toxicity in animal models before drugs and pesticides can enter the market. The US National Research Council of the National Academy of Sciences,in its report,Toxicity Testing in the 21st Century: a Vision and a Strategy [1] ,proposed that toxicity testing should become less reliant on apical endpoints from whole animal tests and eventually rely instead on quantitative,doseresponse models based on information from in vitro assays and in vivo biomarkers,which can be used to screen large numbers of chemicals. The present paper reports about a combination of HTS in vitro assays that can be used to study the potential tumorigenic effect of xenobiotics ( drug targets,environmental chemicals) via a set of"sentinel"genes [2] that are functionally interrelated based on evidence weighted functional linkage network ( FLN ) log-likelihood scores ( Linghu et al [3] ) .展开更多
