Multiple Ionization Cross Sections of Ne and CO Induced by Very High-<i>q</i>Fast Projectiles (<i>q/v</i>>1)

引用

Journal of Applied Mathematics and Physics 2018年第11期6卷 2343-2351页

作者： Man Zhou Zhenye wang Sufen Li Peng Xu haoxin Zhou Rocket Force University of Engineering Xi’an China

In this paper, we extend our previous work of classical over barrier ionization (COBI) model to study the multiple ionization cross section of Ne and CO molecule collided by very high-q fast projectiles(q/v > 1). The model gives similar results to the independent-electron-approximation calculation and is in good agreement with experimental data. The very small computational time required makes it a good candidate for studying the multiple ionization of complex molecules under high linear energy transfers.

Ensemble of single-atom catalysis and defect engineering in Cu/CeOnanozymes for tumor therapy

Science China Chemistry 2023年

作者： haoxin Liu Zhiliang Gao Han Yan Shanqing Li Weiwei wang Xuetao Qin Hongning Sun Jiwei Cui Chunjiang Jia Key Laboratory of Colloid and Interface Chemistry Key Laboratory of Special Aggregated Materials of the Ministry of Education School of Chemistry and Chemical Engineering Shandong University School of Materials and Environmental Engineering Chizhou University

As a class of nanomaterials with natural enzyme-like characteristics, nanozymes have shown their great potential in various applications. Reducible metal oxides featured with defect structures, and single-atom catalysts with isolated metal sites are regarded as two of the most promising nanozymes. However, the strategies to construct highly performed nanozymes by combining these advantages are rarely reported. Herein, we report the coordination-unsaturated single-atomic Cu species supported on sintered CeO2, which combines the advantages of defect engineering and single-atom catalysis, exhibiting a largely enhanced peroxidase(POD)-like activity. The high-temperature calcination induces the transformation of inert Cu1O4species into coordination-unsaturated Cu1O3sites. This novel Cu1O3active sites with an unsaturated coordination work as a new type of defect sites to greatly activate the isolated Cu atoms and accelerate the dissociation of H2O2to form hydroxyl radicals(·OH). The obtained nanozyme with a high POD-like activity possesses low cytotoxicity, showing potential applications for the tumor inhibition in vitro and in vivo.

Prediction of Criminal Suspects Based on Association Rules and Tag Clustering

Journal of Software Engineering and Applications 2019年第3期12卷 35-50页

作者： Bo Cheng Weihong Li haoxin Tong School of Geography South China Normal University Guangzhou China R & D Department Aerospace Finest (Guangdong) Information Technology Co. Ltd. Guangzhou China

To date, not many studies have been conducted on criminal prediction. In this study, the criminal data related to city S is divided into a training data set and a validation data set at a 1:1 ratio in light of the personal tag data and the travel and accommodation data of criminals and ordinary people in city S. Firstly, the FP-growth algorithm is adopted to calculate association rules between the criminals and the ordinary people in their travel and hotel accommodation data, in order to discover criminal suspects based on association rules. Secondly, the DBSCAN algorithm is employed for clustering of the tag data of the criminals and the ordinary people, followed by similarity calculation, in order to discover criminal suspects based on tag clustering. Lastly, intersection operation is performed on the above two sets of criminal suspects, and the resulting intersection is verified against the criminal validation set for elimination of criminals who appear in the intersection so as to obtain final criminal suspects. Results show that a set of 648 criminal suspects is retrieved based on the association rules calculated by the FP-growth algorithm, while a set of 973 criminal suspects is retrieved based on DBSCAN clustering and cosine similarity of the personal tags;the number of criminal suspects is narrowed down to 567 after the intersection operation of the two sets, and 419 of the 567 criminal suspects are further verified to be criminals using the validation set, thereby leaving the other 148 to be the final criminal suspects and giving a prediction accuracy of 73.9%. The data mining method of criminal suspects based on association rules and tag clustering in this study has been successfully applied to the police system of city S, and the experiment proves the effectiveness of this method in detecting criminal suspects.

Agricultural Biotechnology 2014年第1期3卷 38-39,42页

作者： haoxin LV Weidong wang Zhongfang TAN Feifei YANG Yingchun JIAO Yanping wang Zongwei LI Henan Provincial Key Laboratory of Ion Beam Bio-engineering Zhengzhou University Third Affiliated Hospital of Xinxiang Medical University

[ Objective] This study aimed to screen and preliminarily identify LactobaciUus strain CW3. [ Method] Oxford cup double-plate method was used for preliminary screening of broad-spectrum bacteriacin-producing LactobaciUus strain; after eliminating the interference of organic acid and hydrogen peroxide, antibac- terial substances containing protein properties produced by the screened strain were detected; finally, the obtained strain was identified. [ Result] After elimination of interference factors such as organic acid and hydrogen peroxide, the fermentation supernatant of strain CW3 could stil｜ inhibit the growth of indicator strains; the antibacterial activity of fermentation broth was significantly reduced after treatment with trypsase and pepsase, which indicated that the produced antibacterial sub- stances were bacteriocins. Results of physiological and biochemical identification showed that strain CW3 belonged to Lactobacillus plantarum. [ Conclusion] CW3 is a broad-spectrum bacteriocin-producing LactobaciUus plantarum strain.

针对圆柱腔低频声场的球谐函数分解,提出了基于移动式球形传声器阵列（简称球阵）测量的空间域直接求解法。利用空间域测量数据,在压缩感知（Compressive Sensing,CS）理论框架下通过一次线性方程组求解,获得整体坐标系下的声场展开系数。首先讨论了感知矩阵的列相关性,比较不同球阵形式及球面采样点数目,不同球谐函数截断阶数以及空间测量位置等的影响。随后在飞机舱室模型内利用文中提出的方法求解声场展开系数,再现腔内水平面的声压分布,并与传统球坐标变换方法做比较。实验结果表明,利用空间域直接求解法,通过球面随机挑选10个采样点的刚性球阵在声腔3个位置进行声场测量,不仅能够有效求解声场展开系数,而且声场再现精度更高,同时计算效率也显著提高。
