With the arrival of the "post-epidemic era", the impact of multiple factors such as the epidemic and domestic and foreign economic weakness on the employment and entrepreneurship of graduates is still continuing and deepening, and youth employment has become a worldwide problem. Self-employment has gradually become a new employment channel, and self-employment of college students not only provides a large number of new jobs for the society, but also helps to alleviate the social employment pressure and the severe employment situation of college students. At present, exploring the factors influencing college students' entrepreneurial intention has become a hot topic in the field of entrepreneurship research. In this study, it is important to study the mechanism of each factor by constructing a model of the influencing factors of college students' entrepreneurial intention. The main conclusions from the study are as follows. First, all four personality traits have a significant positive influence on entrepreneurial intention, and college students with the above personality traits are more likely to have entrepreneurial intention, and the way of coping with employment pressure plays a mediating role in the relationship between personality traits and entrepreneurial intention. Based on this, the study provides valuable theoretical implications for research in this area and practical implications for how schools can improve students' entrepreneurial awareness.

Li, Yan-Yan,Jiang, Xiao-Ming,Dong, Yi-Guo,Xu, Gang,Ma, Yu-Bo Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.22

Background: This systemic analysis was conducted to evaluate the efficacy and safety of an ifosfamide-containing regimen in treating patients with osteosarcoma. Methods: Clinical studies evaluating the efficacy and safety of Ifosfamide-containing regimen on response and safety for patients with osteosarcoma were identified by using a predefined search strategy. Pooled response rate (RR) of treatment were calculated. Results: When ifosfamide-containing regimens were evaluated, 4 clinical studies which including 134 patients with osteosarcoma were considered eligible for inclusion. Systemic analysis suggested that, in all patients, pooled RR was 44.8% (60/134) in ifosfamide-containing regimens. Major adverse effects were neutropenia, leukopenia, and fatigue inIfosfamide-containing regimens; No treatment related death occurred in cantharidin combined regimens. Conclusion: This systemic analysis suggests that ifosfamide-containing regimens are associated with good response rate and acceptable toxicity in treating patients with osteosarcoma, but this result should be confirmed by randomized clinical trials.

Yan Zhao,Jiang-Bo Yu,Jie Tian 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.3

This paper investigates the global robust output tracking control problem via output feedback for a classof nonlinear uncertain systems with the integral input-to-state stable (iISS) dynamic uncertainties. By performingthe coordinates transformation and employing an extended state observer (ESO), it can be seen that the robust setpointtracking control is well solved. The proposed control strategy simplifies the control design procedure. Thiscontrol scheme finds its application in the mass-spring mechanical system. It is shown that the asymptotic trackingcontrol for any desired displacement can be achieved in the mass-spring mechanical system in the case of unknownparameters. The simulation results demonstrate that the proposed control scheme has a better tracking performance. This verifies the effectiveness of the developed method.

Yan-Min Xie,Yuan-Heng Guo,Fei Zhang,Yue-Peng Yue,Mei-Qiang Feng,Jiang-Bo Zhao 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.21 No.8

Infilling strategies play an important role in kriging based optimization, especially when computationally expensive simulations are involved. In order to improve the efficiency of constructing a high-precision kriging model, an improved expected improvement criterion (IEI) and a parallel infilling strategy are proposed based on the maximum expected improvement (EI) criterion. In the proposed parallel infilling strategy, new sample points are generated by employing IEI criterion coupled with EI criterion. During the improved sampling process, redundant and pseudo sample are deleted in order to avoid failure of constructing a kriging model. An improved weighted particle swarm optimization (WPSO) algorithm is proposed to improve optimization efficiency. The proposed parallel infilling strategy is applied to nonlinear function optimization and variable blank holder force (VBHF) optimization in a double-c stamped part. Based on the LHD and software DYNAFORM, kriging models between the VBHF and forming quality are constructed. Compared with the initial kriging models, the meat relative error of kriging models with the proposed parallel infilling strategy for the wrinkling and average thinning rate are reduced by 95% and 55%, respectively. The optimal VBHF is obtained by the WPSO. The results show that, cracking has been completely eliminated and wrinkling has been decreased, greatly improving the forming quality of the double-c stamped part.

Genome-wide identification and analysis of long noncoding RNAs in longissimus muscle tissue from Kazakh cattle and Xinjiang brown cattle

Yan, Xiang-Min,Zhang, Zhe,Liu, Jian-Bo,Li, Na,Yang, Guang-Wei,Luo, Dan,Zhang, Yang,Yuan, Bao,Jiang, Hao,Zhang, Jia-Bao Asian Australasian Association of Animal Productio 2021 Animal Bioscience Vol.34 No.11

Objective: In recent years, long noncoding RNAs (lncRNAs) have been identified in many species, and some of them have been shown to play important roles in muscle development and myogenesis. However, the differences in lncRNAs between Kazakh cattle and Xinjiang brown cattle remain undefined; therefore, we aimed to confirm whether lncRNAs are differentially expressed in the longissimus dorsi between these two types of cattle and whether differentially expressed lncRNAs regulate muscle differentiation. Methods: We used RNA-seq technology to identify lncRNAs in longissimus muscles from these cattle. The expression of lncRNAs were analyzed using StringTie (1.3.1) in terms of the fragments per kilobase of transcript per million mapped reads values of the encoding genes. The differential expression of the transcripts in the two samples were analyzed using the DESeq R software package. The resulting false discovery rate was controlled by the Benjamini and Hochberg's approach. KOBAS software was utilized to measure the expression of different genes in Kyoto encyclopedia of genes and genomes pathways. We randomly selected eight lncRNA genes and validated them by quantitative reverse transcription polymerase chain reaction (RT-qPCR). Results: We found that 182 lncRNA transcripts, including 102 upregulated and 80 downregulated transcripts, were differentially expressed between Kazakh cattle and Xinjiang brown cattle. The results of RT-qPCR were consistent with the sequencing results. Enrichment analysis and functional annotation of the target genes revealed that the differentially expressed lncRNAs were associated with the mitogen-activated protein kinase, Ras, and phosphatidylinositol 3-kinase (PI3k)/Akt signaling pathways. We also constructed a lncRNA/mRNA coexpression network for the PI3k/Akt signaling pathway. Conclusion: Our study provides insights into cattle muscle-associated lncRNAs and will contribute to a more thorough understanding of the molecular mechanism underlying muscle growth and development in cattle.

Morphology-Controlled Synthesis and Electrochemical Characteristics of Fe2O3 Nanorods

Bo Bai,Xiaole Yan,Gang Li,Pengwei Li,Jie Hu,Huabei Jiang,Wendong Zhang 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2016 NANO Vol.11 No.12

In this work, highly uniform single crystal Fe2O3 nanorods have been synthesized by a facile hydrothermal method in the presence of dihydrogen phosphate ions. Phosphate ions were speculated capping to the sidewalls of Fe2O3 nanocrystals, and resulted in the anisotropic growth of hematite crystals along their [006] zone axis. Fe2O3 nanorods with various aspect ratios have been realized by applying different phosphate concentration of 0.1–0.4 mM. The electrochemical properties of Fe2O3 nanorods showed that the samples with the smallest aspect ratio possessed superior specific capacitance and stability. It was speculated that the larger specific area of the Fe2O3 nanorods with the shortest axial length facilitated the efficient access of electrolyte ions to the electrode surface, and thus would aid in delivering the high pseudocapacitance. These results provide a promising route to obtain the desired hematite-based energy storage materials.

Bo-yan Xu,Xiang-long Liu,Long-long Jiang,Juan Xu 한국자동차공학회 2017 International journal of automotive technology Vol.18 No.3

To obtain an ultralean air-fuel ratio and to reduce engine-out NOX and HC emissions induced by the richer mixture near the spark plug, a spray and wall complex guided combustion system has been developed by utilizing the fuel characteristics of LPG. The new combustion system configuration is optimized by using a commercial CFD code, FIRE V2013, and the reliability of the system has been experimentally demonstrated by Plane Laser-Induced Fluorescence (PLIF). The mixture formation in the new combustion system under part load (2,000 rpm) is numerically simulated. With an injection timing of 40°CA BTDC, the LPG spray which is injected from two upper holes, reaches the ignition point, and the other part of the LPG spray which is injected from the bottom hole, is directed to the ignition point through the vertical vortices at the same time. At the ignition timing of about 20°CA BTDC, the two-part mixtures have been shown to form a stable and richer stratified mixture around the ignition point, and the maximum global air-fuel ratio reaches to 60 : 1.

Bo Yu,Zhongliang Guan,Yan Jiang,Cuiyu Qi,Shifeng Liu 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.5

This paper introduces a new innovative mobile application architecture called "Container-Cloud", which could be probably an inevitable trend in complex cloud, connected devices and network ecosystem in IoE(Internet of Everything) era. The significance of C-C is comparably to Java for web, and android for mobile. There are some innovations in platform operations, in service operations, in developing and in use. The "Container-Cloud" architecture can solve those application silo, enable applications developed, debugged and deployed transparently in cloud, allows mobile applications to be generated on demand, and be migrated and scheduled automatically among cloud, and creates an opportunity for implementation of "context-aware" application in cloud. The paper also gives some "context-aware" application examples based on C-C support in IoE era.

Yan Zhao,Chunxiao Wang,Jiang-Bo Yu 제어·로봇·시스템학회 2018 International Journal of Control, Automation, and Vol.16 No.1

In this paper, the problem of global stabilization control via partial-state feedback is addressed for a class of uncertain nonholonomic systems with the disturbed virtual control directions. The investigated nonholonomic system has the input-to-state stable (ISS) dynamic uncertainties. The small gain theorem and the changing supply function technique are employed to derive a global stabilization controller. Additionally, we develop a switching control strategy in order to get around the smooth stabilization burden associated with nonholonomic systems. The simulation results illustrate the efficacy of the presented algorithm.
