Ziyi He, Fuping Liu, Dewen Wang, Jialin Che, Jialin Che
Open Journal of Clinical Diagnostics (OJCD) , 2014, DOI: 10.4236/ojcd.2014.41008
Abstract: Objective: To investigate the relationship between the single ALT positive (ELSIA-HBV/HCV negative) and NAT-HBV/HCV on blood donor samples. Methods: 28710 samples were surveyed retrospectively from Dec. 2010 to Dec. 2011. ALT was detected by rate method, and the single ALT positive samples were detected by ELSIA-HBV/HCV and NAT-HBV/HCV. The relationship between the single ALT positive and NAT-HBV/HCV were analyzed. 21 samples, values in 40 U/L ≤ ALT ≤ 70 U/L, were selected at random from 2516 samples with single ALT positive, which were second detected by ELISA and NAT in the second donation. Results: 2516 (8.74%) single ALT positive samples (ELSIA-HBV/HCV negative) were found in 28710 donors. Among these samples, 8 (2.8/10000) positive were detected by NAT, including 5 HBV-DNA-positive and 3 HCV-RNA-positive. Obviously, positive rate of NAT from the donors whose ALT value ≤ 70 U/L were lower than those of ≥ 71 U/L (P < 0.01). 21 donors were investigated in the second donation in following 153 to 401 days, All samples were negative by ELISA-HBV/HCV and NAT-HBV/HCV. Conclusions: Donors with single ALT positive (value in 40 U/L-70 U/L) are not likely to become HBV/HCV virus carriers or HBV/HCV patients after half or one year. So it is to set ALT abandone threshlod to ≤ 70 U/L can ensure blood safety, and reduce blood abandone in our center.
Modified equations for weak stochastic symplectic schemes via their generating functions
Lijin Wang,Jialin Hong
Mathematics , 2014,
Abstract: In this paper, a systematic approach of constructing modified equations for weak stochastic symplectic methods of stochastic Hamiltonian systems is given via using the generating functions of the stochastic symplectic methods. This approach is valid for stochastic Hamiltonian systems with either additive noises or half-multiplicative noises, and we prove that the modified equation of the weak stochastic symplectic methods are perturbed stochastic Hamiltonian systems of the original systems, which reveals in certain sense the reason for the good long time numerical behavior of stochastic symplectic methods.

Approximation of Invariant Measure for Damped Stochastic Schr?dinger Equation via Ergodic Full Discretization
Chuchu Chen,Jialin Hong,Xu Wang
Mathematics , 2015,
Abstract: We study the approximation of invariant measure for an ergodic damped stochastic nonlinear Schr\"{o}dinger equation (NLSE) with additive noise. A spatial semi-discrete scheme and a fully discrete scheme for the damped stochastic NLSE are proposed. The ergodicity of the numerical solutions of both spatial semi-discretization and full discretization are proved. Also, we show that the approximation errors of invariant measure are $N^{-1}$ in spatial direction and $\tau^{\frac12}$ in temporal direction.
Evolution of resistive switching polarity in Au/Ar+ bombarded SrTi0.993Nb0.007O3/In sandwiches

Chinese Science Bulletin , 2012, DOI: 10.1007/s11434-011-4859-3
Abstract: We investigated the resistive switching characteristics of Au/Ar+ bombarded SrTi0.993Nb0.007O3/In sandwiches. The evolution of the resistive switching polarity with sweeping voltage was observed. Our experiments showed that under a macroscopic electrode the homogeneous trapping-detrapping-type conduction and filament-type conduction coexist and compete with each other. For a large sweeping voltage range, the trapping-detrapping-type conduction dominates. However, for a small range the latter dominates. If the bias voltage is too large, the filament conduction could be destroyed. These results will help deepen the understanding of the resistive switching polarity, and will aid in future device design.

Journal of Human Resource and Sustainability Studies (JHRSS) , 2015, DOI: 10.4236/jhrss.2015.33016
Abstract: Human resource departments of large public hospitals in China deal with new challenges caused by multi-campus structure, such as increased labor demand, difficulty in cost management, lack of professional talents, restriction on employing way and etc. Delphi Method and Focus Group were used as the chief methods to analyze the problems. Countermeasures are researched as staffing optimization, performance management, forming Expert Center, establishing HRM Framework based on the positions among campus and restricting the human resource department. The researches break away from traditional human resource practices, develop new application for future trends, and adapt to the changes of business in the country’s public hospital reform.
Fabrication and Analysis of Vanadium-Based Metal Powders for Selective Laser Melting  [PDF]
Jialin Yang, Jingfeng Li
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2018, DOI: 10.4236/jmmce.2018.61005
Abstract: Vanadium Alloy is a type of advanced nuclear material with many ideal properties compared as traditional nuclear materials, which has very wide and important application in first-wall and blanket structural material for fusion power plant applications. So it has attracted increasing attentions, especially on new manufacturing methods, such as selective laser melting and so on. In this paper, the comparative study of the powders obtained by mechanical mixing method, dry grinding method and wet grinding method respectively was performed to evaluate the effect of ball milling process on the microstructure and degree of alloying of the vanadium-based powder mixtures with the nominal composition of V5Cr5Ti vanadium alloy. The powders prepared by dry grinding method exhibits better spherical-like morphology and degree of alloying than those prepared by mechanical mixing method and wet grinding method, which indicates that dry grinding method can be used to prepare the superfine vanadium alloy powders for selective laser melting. This work provides a new method as well as important insights into the preparation of superfine vanadium alloy powders for selective laser melting additive manufacturing technology.
Centrality-based pathway enrichment: a systematic approach for finding significant pathways dominated by key genes
Zuguang Gu, Jialin Liu, Kunming Cao, Junfeng Zhang, Jin Wang
BMC Systems Biology , 2012, DOI: 10.1186/1752-0509-6-56
Abstract: A systematic and extensible pathway enrichment method in which nodes are weighted by network centrality was proposed. We demonstrate how choice of pathway structure and centrality measurement, as well as the presence of key genes, affects pathway significance. We emphasize two improvements of our method over current methods. First, allowing for the diversity of genes’ characters and the difficulty of covering gene importance from all aspects, we set centrality as an optional parameter in the model. Second, nodes rather than genes form the basic unit of pathways, such that one node can be composed of several genes and one gene may reside in different nodes. By comparing our methodology to the original enrichment method using both simulation data and real-world data, we demonstrate the efficacy of our method in finding new pathways from biological perspective.Our method can benefit the systematic analysis of biological pathways and help to extract more meaningful information from gene expression data. The algorithm has been implemented as an R package CePa, and also a web-based version of CePa is provided.As omics and high throughput technology continues to develop, researchers can increasingly understand biological phenomena at the systems level; that is, can elucidate the complicated interactions between genes and molecules responsible for biological functions [1]. Microarray technology has been widely used to measure gene expression profiles and has produced huge amounts of data for biological analysis [2]. However, traditional single gene analysis tells us little about the cooperative roles of genes in real biological systems. New challenges for microarray data analysis are to find specific biological functions affected by a group of related genes. Biological pathways are sets of genes or molecules that act together by chemical reactions, molecule modifications or signalling transduction to carry out such functions [3]. Since pathways are essentially integrated ci
Lasing on pyroclastic rocks: A case study of 40Ar/39Ar dating on Moshishan Group, eastern Zhejiang Province

Chinese Science Bulletin , 2008, DOI: 10.1007/s11434-008-0415-1
Abstract: It is difficult to date pyroclastic rocks, for almost all the dating methods, due to the multiple sources during their formation. 40Ar/39Ar incremental heating results on groundmass selected from the samples show that the age spectra are meaningless geologically. However, singe crystal total fusions of CO2 lasing on the sanidine separates could yield rational 40Ar/39Ar results and distinguish their sources in this study. Timing on three formations of the Moshishan Group, after avoiding the exotic and altered grains by lasing on the single sanidine separate, was reported in this paper. The lowermost portion of the Chawan Formation gives an age of 113.7±0.3 Ma; the lower part of the Xishantou Formation was formed 116.4±0.4 Ma ago and the bottom of the Gaowu Formation took its shape at 118.4±0.4 Ma. These new ages are much younger than the previous ones, suggesting that these thick volcanic formations had been formed in very short durations.
