Objective: This study aimed to reveal the protective effect of hydrogen storage nanomaterial MgH2 on radiationinduced male fertility impairment. Methods: The characterization of MgH2 were analyzed by scanning electron microscopy (SEM) and particle size analyzer. The safety of MgH2 were evaluated in vivo and in vitro. The radioprotective effect of MgH2 on the reproductive system were analyzed in mice, including sperm quality, genetic effect, spermatogenesis, and hormone secretion. ESR, flow cytometry and western blotting assay were used to reveal the underlying mechanisms. Results: MgH2 had an irregular spherical morphology and a particle size of approximately 463.2 nm, and the content of Mg reached 71.46%. MgH2 was safe and nontoxic in mice and cells. After irradiation, MgH2 treatment significantly protected testicular structure, increased sperm density, improved sperm motility, reduced deformity rates, and reduced the genetic toxicity. Particularly, the sperm motility were consistent with those in MH mice and human semen samples. Furthermore, MgH2 treatment could maintain hormone secretion and testicular spermatogenesis, especially the generation of Sertoli cells, spermatogonia and round sperm cells. In vitro, MgH2 eliminated the [·OH], suppressed the irradiation-induced increase in ROS production, and effectively alleviated the increase in MDA contents. Moreover, MgH2 significantly ameliorated apoptosis in testes and cells and reversed the G2/M phase cell cycle arrest induced by irradiation. In addition, MgH2 inhibited the activation of radiation-induced inflammation and pyroptosis. Conclusion: MgH2 improved irradiation-induced male fertility impairment by eliminating hydroxyl free radicals.

Excited states of 113In have been populated through the heavy-ion fusion evaporation reaction 110Pd(7Li, 4n)113In. A new band with the configuration of a proton d5/2 orbital is identified. Two ΔI = 2 intruder bands, built on the πh11/2 and the πg7/2 orbitals, have been extended to spins (63/2-)ħ and (55/2+)ħ, respectively. The negative-parity πh11/2 intruder band shows a smooth increase in aligned spin, which is attributed to a strong proton-neutron interaction. The properties of the positive-parity πg7/2 band are discussed based on tilted axis cranking model calculations, and the features of the antimagnetic rotation for this band are shown after backbend. Furthermore, the contributions of the two-shears-like mechanism, the neutron (gd)ν shell and the core rotation are investigated for the positive-parity πg7/2 band.

Global Financial Crisis and China's Transition: Balancing Market Power with Active Role of the Government

Jing Ma,LIHUI TIAN 한국국제경제학회 2012 International Economic Journal Vol.26 No.3

China's transition is uncompleted in terms of privatization and of government intervention into economic activities. However, China performed relatively well in handling the 1997 Asia Financial Crisis and the 2008 American Financial Storm, as it keeps a strong government on both macro-economic management and corporate activities. This paper provides some evidence from China to support the theories of developmentalists on the active role of governments in economic development and market failures. We argue that the success of transition requires a balance of market power and government regulations.

Evaluation of Resource-based Provincial Innovation Environment Index System Based on Open Innovation Theory

Jing Ma,Yeon-Ho Seong(성연호),Min-Kyu Lee(이민규) 한국혁신학회 2021 한국혁신학회지 Vol.16 No.4

지역의 각 혁신 주체가 고품질의 혁신 성과를 창출하기 위해서는 적절한 혁신 환경이 필수적으로 요구된다. 중국의 경우 각 지역별로 상당한 수준의 자원 차이가 나타나기 때문에 혁신 주도 효율성을 개선하기 위해서는 지역별 혁신 환경의 특성과 주요 영향 요인을 정확하게 파악하는 것이 필요하다. 이에 본 연구에서는 개방형 혁신 이론과 관련 선행연구 조사를 통해 중국의 지역혁신 환경 평가체계를 구축하였다. 해당 평가체계는 크게 2차원(과정, 내용)으로 구성하였으며, 세부적으로는 3개의 2차 지표(제도 및 인간 환경, 기반시설 환경, 시장 환경)와 19개의 3차 지표로 구분하였다. 평가체계를 활용하여 대표적인 자원 의존 지역인 산시성을 실증분석 해본 결과 혁신 환경의 발전은 주기적이며 반복적인 개발 법칙을 보였으며, 국가 차원의 거시 정책에 큰 영향을 받는 것으로 나타났다. 아울러, 지표별로는 제도 및 인간 환경 부문의 변화가 가장 주요한 것으로 분석되었으며 시장 환경 부문은 시차를 나타내는 것으로 분석되었다. A good innovation environment is the prerequisite for each innovation subject in a region to produce high-quality innovation performance. Due to the significant heterogeneity of resources in various regions and provinces in China, an accurate grasp of the characteristics and key influencing factors of the local innovation environment is the basis for improving innovation-driven efficiency. Based on the systematic review of research literature and from the perspective of open innovation theory, this study constructed a provincial innovation environment evaluation system consisting of two dimensions of process and content, three secondary indicators of institutional and cultural environment, infrastructure environment and market environment, and 19 three-level indicators. The empirical analysis of Shanxi Province, a typical resource-dependent province, reveals that the evolution of innovation environment presents a periodical and iterative development law, and is significantly affected by national macro-policy. The change in institutional and cultural environment dimension is the most stable, the change of infrastructure environment dimension is the most significant, and the change of market environment dimension shows time lag.

Research on Line Overload Emergency Control Strategy Based on the Source-Load Synergy Coefficient

Jing Ma,Wenbo Kang,James S. Thorp 대한전기학회 2018 Journal of Electrical Engineering & Technology Vol.13 No.3

A line overload emergency control strategy based on the source-load synergy coefficient is proposed in this paper. First, the definition of the source-load synergy coefficient is introduced. When line overload is detected, the source-load branch synergy coefficient and source-load distribution synergy coefficient are calculated according to the real-time operation mode of the system. Second, the generator tripping and load shedding control node set is determined according to the source-load branch synergy coefficient. And then, according to the line overload condition, the control quantity of each control node is determined using the Double Fitness Particle Swarm Optimization (DFPSO), with minimum system economic loss as the objective function. Thus load shedding for the overloaded line could be realized. On this basis, in order to guarantee continuous and reliable power supply, on the condition that no new line overload is caused, some of the untripped generators are selected according to the source-load distribution synergy coefficient to increase power output. Thus power supply could be restored to some of the shedded loads, and the economic loss caused by emergency control could be minimized. Simulation tests on the IEEE 10-machine 39-bus system verify the effectiveness and feasibility of the proposed strategy.

Information Fusion Filter for Multi-rate Multi-sensor Systems

Jing Ma,Hao Jin,Tian Tian,Wei Zhang 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.1

This paper is concerned with the information fusion filtering problem for a class of multi-rate multi-sensor systems, where the system is described at the highest sampling rate and different sensors may have different lower sampling rates. Firstly, the local filters (LFs) at state updating points are proposed by using the LFs at measurement sampling points. Then, the distributed suboptimal fusion filter is obtained by the well-known covariance intersection fusion (CIF) algorithm. The filtering error variance matrices are derived to obtain the fusion weights. The computational cost is reduced since the cross-covariance matrices between any two local filters are avoided. Simulation example verifies the correctness and feasibility of the proposed algorithm.

Ma, Xue-Lei,Li, Yan-Yan,Zhang, Jing,Huang, Jing-Wen,Jia, Hong-Yuan,Liu, Lei,Li, Ping Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

Background: Isolation and characterization of circulating tumor cells (CTCs) in patients suffering from a variety of different cancers have become hot biomarker topics. In this study, we evaluated the prognostic value of CTCs in pancreatic cancer. Materials and Methods: Initial literature was identified using Medline and EMBASE. The primary data were hazard ratios (HRs) with 95% confidence intervals (CIs) of survival outcomes, including overall survival (OS) and progression free survival/recurrence free survival (PFS/RFS). Results: A total of 9 eligible studies were included in this meta-analysis, published between 2002 and 2013. The estimated pooled HR and 95%CI for OS for all studies was 1.64 (95%CI 1.39-1.94, p<0.00001) and the pooled HR and 95%CI for RFS/DFS was 2.36 (95%CI 1.41-3.96, p<0.00001). The HRs and 95%CIs for OS and RFS/DFS in patients before treatment were 1.93 (95%CI 1.26-2.96, p=0.003) and 1.82 (95%CI 1.22-2.72, p=0.003), respectively. In patients receiving treatment, the HRs and 95%CI for OS and RFS/DFS were 1.37 (95%CI 1.00-1.86, p=0.05) and 1.89 (95%CI 1.01-3.51, p=0.05), respectively. Moreover, the pooled HR and 95%CI for OS in the post-treatment group was 2.20 (95%CI 0.80-6.02, p=0.13) and the pooled HR for RFS/DFS was 8.36 (95%CI 3.22-21.67, p<0.0001). Conclusions: The meta-analysis provided strong evidence supporting the proposition that CTCs detected in peripheral blood have a fine predictive role in pancreatic patients especially on the time point of post-treatment.
