A new species, Euops pseudlespedezae Li. sp. nov., is described from China, which was collected from Tianqiaoling, in the Jilin Province of China. The new species is closely related to Euops lespedezae lespedezae Sharp, which was also recorded for the first time in China.

Li Zhanying,Xing Jun,Li Bo,Wang Jue 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.4
Chaotic diagonal recurrent neural network is optimized and proposed to predict ship rolling motion. Aiming at the traditional arithmetic deductions of each weight value mediate do not give the specific sample time, it makes some lacks in this kind of deduction, the paper tries to optimize sampling time, carried out the derivation of the weight training and a convergence theorem of each weight learn algorithm based on Lyapunov function is given and proofed. Simulation results demonstrate the use of optimal sampling times increases the accuracy of all of the weight and algorithm convergence, to advance predicted precision so that forecast time of ten seconds efficiently. obviously better than using feed-forward BP neural network to predict.

The most basic methodology for describing urban spatial organizations is spatial syntax. However, there is a limit to using only spatial syntax to explore the connection of urban street spaces. At this time, another possible way is needed. The method of connecting space through Enclosing Balance is well expressed. However, the connection in this program is space contact connection, whereas the connection recognized in the direct human view is space string connection. So in preparation for these two connections, we need to find out how they are related.

Background: Excision repair crossing-complementing group 2 (ERCC2), also called xeroderma pigmentosum complementary group D (XPD), plays a crucial role in the nucleotide excision repair (NER) pathway. Previous epidemiological studies have reported associations between ERCC2 polymorphisms and non-Hodgkin lymphoma (NHL) risk, but the results have remained controversial. Materials and Methods: We conducted this meta-analysis based on eligible case-control studies to investigate the role of two ERCC2 polymorphisms (Lys751Gln and Asp312Asn) in determining susceptibility to NHL. Ten case-control studies from several electronic databases were included in our study up to August 14, 2014. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed- or random-effects models to estimate the association strength. Results: The combined results based on all studies did not show any association between Lys751Gln/Asp312Asn polymorphisms and NHL risk for all genetic models. Stratified analyses by histological subtype and ethnicity did not indicate any significant association between Lys751Gln polymorphism and NHL risk. However, a significant reduced risk of NHL was found among population-based studies (Lys/Gln versus Lys/Lys: OR=0.87, 95% CI=0.77-0.99, P=0.037) but not hospital-based studies. As for Asp312Asn polymorphism, there was no evidence for the association between this polymorphism and the risk of NHL in all subgroup analyses. Conclusions: This meta-analysis suggests that there may be no association between Lys751Gln/Asp312Asn polymorphism and the risk of NHL and its two subtypes, whereas ERCC2 Lys751Gln heterozygote genotype may provide protective effects against the risk of NHL in population-based studies. Therefore, large-scale and well-designed studies are needed to clarify the effects of haplotypes, gene-gene, and gene-environment interactions on these polymorphisms and the risk of NHL and its different histological subtypes in an ethnicity specific population.
Breast Cancer Diagnosis Using Cluster-based Undersampling and Boosted C5.0 Algorithm
Jue Zhang,Li Chen,Jian-xue Tian,Fazeel Abid,Wusi Yang,Xiao-fen Tang 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.5
Learning from imbalanced data set is relatively new challenge for breast cancer diagnosis, where the diseases cases are often quite rare relative to normal population. Although traditional algorithms are all accuracyoriented which result biased towards the majority class. The combinations of sampling methods with ensemble classifiers have shown certainly good performance. In this paper, a hybrid of cluster-based undersampling and boosted C5.0 is proposed. The proposed classification model consists of two phases: cluster analysis and classification. In cluster analysis, affinity propagation algorithm is used to define the number of clusters, and then the k-means clustering is utilized to select the border and informative samples. In the classification phase, C5.0 algorithm is used in conjunction with boosting technical, owing to leverage the strength of the individual classifiers. The proposed algorithm is assessed by 14 benchmark imbalanced data sets taken from UCI dataset repository. The extensive experimental results on different imbalanced datasets demonstrated that the proposed algorithm can achieve better classification performance in terms of Matthews’ Correlation Coefficient (MCC) as compared to other existing imbalanced dataset classification algorithms.

With the development of cloud computing technology, people not only want to pursue the shortest time to complete the tasks by using cloud computing, but also hope to take into the running costs of machines. Existing task scheduling algorithm in the cloud computing environment has been unable to meet people's needs. As an extension and generalization of the model checking theory, probability model checking is also used in many fields, such as random distributed algorithm and other areas. The task scheduling algorithm based on the particle swarm optimization algorithm combined with probability model is proposed in this paper. The algorithm defines the fitness functions of the time cost and the running cost. The fitness functions can improve the efficiency of the cloud computing platform. At the same time, the probability model can be used to analyze the running states of machines and the computing capability of the nodes in the cloud cluster. The probability, which is calculated by the probability model, provides the basis for changing particle swarm algorithm’s the inertia factor and the learning factor, so as to solve the drawback that the inertia factor and the learning factor solely depend on the fixed value.
A Two-stage Control Scheme for a Dual-Bridge Series Resonant Converter
Yi-jue Zhang,Ming Lu,Xiaodong Li 전력전자학회 2015 ICPE(ISPE)논문집 Vol.2015 No.6
High frequency (HF) isolated dual-bridge converters are featured with high power density, high efficiency for bidirectional applications, such as distributed generation systems. In this paper a high-frequency isolated dual-bridge series resonant converter (DBSRC) with a novel two-stage control scheme is proposed for an application with a wide variation of voltage gain. The dual-phase-shift control is adopted for the DBSRC. The steady-state analysis of the DBSRC is performed by means of the fundamental harmonics approximation. A novel control scheme is presented for the converter with a 40% variation in converter gain. It can be seen that zero-voltage switching is kept for all switches on the low-voltage side and half of switches on the HV side. Also, there is no circulation energy on the LV side for full load operation. Verification of the analysis and design are performed through simulation and experimental test at last.
