Impact of Multi-Threading Strategy on Performance of End-to-End File Transmission in a Real Network
Authors: Dong Wei
Published: May 2014

In this paper, we conduct research on the impact of multi-threading strategy on performance of end-to-end file transmission. As we all know, adopting multi-threading strategy in file transmission can greatly improve performance. However, the degree of such performance gains is not well documented. We first analyze the merits of file transmission utilizing multi-threaded transmission method. Then, to demonstrate the performance gains of multi-threaded transmission, an architecture which supports multi-threading transmission both in client side and server side is designed. We utilize the architecture in a real network and compare transmission performance by utilizing different parameters. Test results shows that multi-threading transmission achieves a better performance when compared to single-thread transmission. However, the performance gains are not proportional to the number of threads. Since file transmission is very normal in our daily life, it is expected the results in this paper will provide a guide for software vendor when multi-threading tools are developed.

Authors: Lin Hua , Hong Xia , Ping Zhou
Published: May 2014

Rheumatoid arthritis (RA) is a complex disease determined by multilocus genetic factors. Although genome-wide association studies have been proven to be a powerful approach to identify risk loci, the molecular regulatory mechanisms of RA are still not clearly understood. It is therefore important to consider the interplay between genetic factors and biological networks in elucidating the mechanisms of RA pathogenesis. Here, we applied the complexity of Protein-Protein Interaction (PPI) network to identify disease risk genes. First, we assigned risk SNPs to genes from UCSC genome database and mapped these genes to PPI networks. With the aid in PPI networks, gene modules were extracted and risk feature genes were identified. As a result, risk feature genes, such as CD40, PKCA, were identified as significant risk gene sets associated with RA.

The mean value of the small-scale range (1.12-1.85 km) is approximately 1.50 km, that of the medium-scale range (3.40-4.10 km) is approximately 3.8 km, and that of the large-scale range (9.35-10.10 km) is approximately 9.8 km. The correlations between each factor on the four scales vary, and the correlation between each factor on the medium scale is the strongest. In this paper, the ecological factors of the farmland on the medium scale have relatively consistent variability and sources, indicating that all of the factors on that scale have a high coordination.

Heavy oil, with the characteristics of high viscosity and large density, is the most important component of petroleum hydrocarbon energy. In reservoir exploration, its dynamic resistance not only reduces driven efficiency, but also brings much more exploration difficulty, so it is not feasible to exploit heavy oil with conventional methods. Previous studies have carried heavy oil research , but few have attempted to examine the impact of heavy oil on reservoir properties .In this paper, a detailed analysis of heavy oil distribution and remaining oil distribution of G6 block is performed. The conclusion are drawn: the local water flooding and local remaining oil selectively accumulation are caused by heavy oil through reducing water flooding efficiency; As to heavy oil recovery, appropriate exploration should be selected to reduce viscosity of heavy oil according to different geological conditions.

Published: May 2014

The objective of this study was to examine microstructural changes of cement mortar due to elevated temperature from 105 to 500°C. Changes at the meso and microscopic levels were followed by nitrogen adsorption desorption isotherms, from which the pores size distributions and specific surface areas were determined. The results show a decrease in volume of micropores and an increase in volume of mesopores which reflect clearly the shrinkage and structural transformation of the calcium silicate hydrate due to high temperature.

Alginate-chitosan multilayer beads containing α-glucosidase inhibiting peptide (GIP) from Ruditapes philippinarum were prepared to develop stable, non-toxic microcapsules. The optimal conditions were alginate concentration (w/v) 1.0%, alginate/GIP ratio (w/w) 1:5, calcium chloride concentration (w/v) 5% and chitosan concentration (w/v) 2.0%, which were obtained through single factor tests and orthogonal experiments. Under the conditions, the encapsulation efficiency (EE%) was 67.21% and the drug-loading percentage was 33.67%.According to the release study, the release rate of GIP was lower than 30% after incubation in simulated gastric fluid (SGF) for 3h and the rate was higher than 70% after incubation in simulated intestinal fluid (SIF) for 5h. The inhibiting rate was 25.13% after treatment in SIF when the concentration of GIP was 10mg/mL. Accordingly,the microcapsules prepared in this paper are acid resistant and therefore can be given orally.

Published: May 2014

This paper presents a simulation modeling of epidemic with the isolated intervention based on the theory of Cellular Automata, which is considering the heterogeneity and mobility of the individuals. An idea of the random walk Cellular Automata is used to reflecting the characteristics of the mobility of individuals, by defining the proportion and the largest step of individuals’ movement. What’s more, the model simulates the impact of the disease duration and the isolated intensity on the spreading of epidemic, and the simulation result is coincidence with the macroscopic characteristics of epidemic controlled by isolation intervention. It offers powerful theoretical support for the government to prevent and control the spread of epidemic.

Abstract:Objective: To investigate whether any association exists between genetic polymorphism in CYP2B6 c.516G>T and individual susceptibility to acute lymphoblastic leukemia (ALL). Methods: Our study group consisted of 96 ALL patients(T-ALL 17 cases, B-ALL 79 cases) and 348 unrelated healthy newborn volunteers as a control group. Genomic DNA was extracted from peripheral blood and cord blood leukocytes. We genotyped CYP2B6 c.516G>T polymorphism by use of PCR with sequence-specific primers (PCR-SSP). The data were analyzed statistically using chi-square and logistic regression analyses. Results: The frequencies of GG genotype were 74.14%, 57.29%, 29.41% and 63.29%, and GT genotype were 23.85%, 37.50%, 64.71% and 31.65%, and TT genotype were 2.01%, 5.21%, 5.88% and 5.06% in control group, ALL, T-ALL, and B-ALL cases, respectively. Chi-square test showed a signiﬁcant correlation between the CYP2B6 c.516G>T polymorphism GT genotype and ALL patients (OR=2.035, 95%CI=1.249-3.313, P=0.004); and T-ALL patients (OR=6.839, 95%CI=2.309-20.252, P=0.000); whereas and B-ALL patients (OR=1.554, 95%CI=0.906-2.667, P=0.108). Conclusions: This study revealed the CYP2B6 c.516GT genotype may be a risk factor to the development of ALL, especially T-ALL.
