Tiantian Wang,Jing Wang,Haipeng Wang,Jie Meng,Chunlei Yu,Shuxia Wang 한국인터넷정보학회 2023 KSII Transactions on Internet and Information Syst Vol.17 No.4

Fractional repetition (FR) codes can achieve exact uncoded repair for multiple failed nodes, with lower computational complexity and bandwidth overhead, and effectively improve repair performance in distributed storage systems (DSS). The actual distributed storage system is dynamic, that is, the parameters such as node storage overhead and number of storage nodes will change randomly and dynamically. Considering that traditional FR codes cannot be flexibly applied to dynamic distributed storage systems, a new construction scheme of adaptive-and-resolvable FR codes based on hypergraph coloring is proposed in this paper. Specifically, the linear uniform regular hypergraph can be constructed based on the heuristic algorithm of hypergraph coloring proposed in this paper. Then edges and vertices in hypergraph correspond to nodes and coded packets of FR codes respectively, further, FR codes is constructed. According to hypergraph coloring, the FR codes can achieve rapid repair for multiple failed nodes. Further, FR codes based on hypergraph coloring can be generalized to heterogeneous distributed storage systems. Compared with Reed-Solomon (RS) codes, simple regenerating codes (SRC) and locally repairable codes (LRC), adaptive-and-resolvable FR codes have significant advantages over repair locality, repair bandwidth overhead, computational complexity and time overhead during repairing failed nodes.

Shuxia Wang 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.9

The development of small and medium-sized enterprises is greatly affected by the entrepreneurs. In recent years; network learning becomes an important way to achieve the advanced competitiveness, which provides rich information and resources for entrepreneurs and staffs. Network learning refers to a study activity through online system; it mainly uses the autonomous learning and consultation learning methods. In comparison with the traditional learning activities, online learning has the following three characteristics: the first is to share the rich network learning resources; the second is the individual learning and collaborative learning; the third is it can break space and time limit. With the universal of building the learning websites, learning resources become more and more abundant in content, quantity, type, distribution, dissemination way and the propagation velocity, etc. It creates a more complicated space of information. Therefore, it is an important problem to establish a scientific, systematic and operable evaluation system, in order to provide support for organization, development and utilization of online learning resources.

Minimum Bandwidth Regenerating Codes Based on Cyclic VFR Codes

( Jing Wang ),( Shuxia Wang ),( Tiantian Wang ),( Xuefei Zhang ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.7

In order to improve the reliability and repair efficiency of distributed storage systems, minimum bandwidth regenerating (MBR) codes based on cyclic variable fractional repetition (VFR) codes are constructed in this thesis, which can repair failed nodes accurately. Specifically, in order to consider the imbalance of data accessed by the users, cyclic VFR codes are constructed according to that data with different heat degrees are copied in different repetition degrees. Moreover, we divide the storage nodes into groups, and construct MBR codes based on cyclic VFR codes to improve the file download speed. Performance analysis and simulation results show that, the repair locality of a single node failure is always 2 when MBR codes based on cyclic VFR codes are adopted in distributed storage systems, which is obviously superior to the traditional MBR codes. Compared with RS codes and simple regenerating codes, the proposed MBR codes based on cyclic VFR codes have lower repair locality, repair complexity and bandwidth overhead, as well as higher repair efficiency. Moreover, relative to FR codes, the MBR codes based on cyclic VFR codes can be applicable to more storage systems.

Wang Xiuli,Song Yunquan,Zhang Shuxia 한국통계학회 2020 Journal of the Korean Statistical Society Vol.49 No.3

In this paper, we study the weighted quantile average estimation technique for the parameter in additive partially linear models with missing covariates, which is proved to be an efficient method. The proposed method is based on optimally combining information over different quantiles via multiple quantile regression. We establish asymptotic normality of the weighted quantile average estimators when the selection probability is known, estimated using the non-parametrical method and parametrical method, respectively. Moreover, we compute optimal weights by minimizing asymptotic variance and then obtain the corresponding optimal weighted quantile average estimators. To examine the finite performance of our proposed method, we use the numerical simulations and apply to model time sober for the patients from a rehabilitation center. Simulation results and data analysis further verify that the proposed method is an efficient and safe alternative to both theWCQRmethod andWLSmethod.

Caspase-3 inhibitor inhibits enterovirus D68 production

Wenbo Huo,Jinghua Yu,Chunyu Liu,Ting Wu,Yue Wang,Xiangling Meng,Fengmei Song,Shuxia Zhang,Ying Su,Yumeng Liu,Jinming Liu,Xiaoyan Yu,Shucheng Hua 한국미생물학회 2020 The journal of microbiology Vol.58 No.9

Enterovirus D68 (EVD68) is an emerging pathogen that recently caused a large worldwide outbreak of severe respiratory disease in children. However, the relationship between EVD68 and host cells remains unclear. Caspases are involved in cell death, immune response, and even viral production. We found that caspase-3 was activated during EVD68 replication to induce apoptosis. Caspase-3 inhibitor (Z-DEVDFMK) inhibited viral production, protected host cells from the cytopathic effects of EVD68 infection, and prevented EVD68 from regulating the host cell cycle at G0/G1. Meanwhile, caspase-3 activator (PAC-1) increased EVD68 production. EVD68 infection therefore activates caspase-3 for virus production. This knowledge provides a potential direction for the prevention and treatment of disease related to EVD68.
