Task scheduling and resource allocation are two core techniques in cloud computing. In order to use resource efficiently in heterogeneous environment, the paper presents an new task scheduling algorithm based on Genetic Algorithm (GA). The model considers four aspects of the task scheduling: task finished time, task expenses, bandwidth and reliability in(More)
Previous studies in cancer biology suggest that chemotherapeutic drug resistance and tumor relapse are driven by cells within a tumor termed 'cancer stem cells'. In the present study, a Hoechst 33342 dye exclusion technique was used to identify cancer stem‑like side population (SP) cells in colon carcinoma, which accounted for 3.4% of the total cell(More)
The objective of this study was to investigate gene transcription profiles of the stage IV ovary and the ovotestis of the rice field eel (Monopterus albus) in an attempt to uncover genes involved in sex reversal and gonad development. Suppression subtractive hybridization (SSH) libraries were constructed using mRNA from the stage IV ovary and the ovotestis.(More)
We consider high-dimensional location test problems in which the number of variables p may exceed the sample size n. The classical T 2 test does not work well because the contamination bias in estimating the covariance matrix grows rapidly with p. Unlike most existing remedies abandoning all the correlation information, the composite T 2 test developed here(More)
Delivery ratio of large file transmission in opportunistic networks is low for the characteristics of opportunistic networks. In order to improve the ability of transferring large files, a kind of data fragmentation strategy is proposed in this paper: self-adaptive data fragmentation (SADF). The size of data fragment in SADF is based on historical statistic(More)
Generalized approximate message passing (GAMP) is an effective algorithm for recovering signals from noisy linear measurements, assuming known a priori signal distributions. However, in practice, both the signal distribution and noise level are often unknown. The EM-GM-AMP algorithm integrates GAMP with the EM algorithm to simultaneously estimate the signal(More)
Microcystin-LR (MC-LR) is the most frequently studied cyclic heptapeptide hepatotoxin produced by cyanobacteria. The toxin accumulates rapidly in the liver where it exerts most of its damage, but the molecular mechanisms behind its toxicity remain unclear. Here, suppression subtractive hybridization (SSH) was used to identify alterations in gene(More)
