| 1 | Advanced noble-metal-free bifunctional electrocatalysts for metal-air batteries显示文摘The sluggish reaction kinetics at the oxygen cathode is one of the important issues hindering the commercialization of the metal-air batteries.Although the noble metal can be used as the high-efficiency electrocatalyst to solve the problems to some extent,the high cost and scarcity of these noble-metal catalysts have limited their application in electrocatalysis.In this review,we discussed the mecha-nisms of the ORR and OER,and proposed the principles for the bifunctional electrocatalysts firstly,and then the state-of-the-art bifunctional catalysts,including carbon-based materials and transition-metal-based materials.On the basis of that,the self-supporting 3D noble-metal-free bifunctional ORR/OER catalysts were also discussed.Finally,the perspectives for the bifunctional electrocatalysts were discussed. | Wenhao Tang Boya Li Kewei Teng Xiaodong Wang Ruiping Liu Mengwei Wu Lei Zhang Pengfei Ren Junqing Zhang Ming Feng | 2022 | Journal of Materiomics2022，8，2： | 2 |
| 2 | Computational Identification of Small Interfering RNA Targets in SARS CoV-2显示文摘Dear Editor,At the end of 2019,a new virus,called Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2)was reported(Benvenuto et al.2020;Zhu et al.2020).The sequences of SARS-CoV-2 reported by different research groups demonstrated that it is a positive strand RNA virus.The sequence of SARS-CoV-2 is approximately 30 kb long,and could encodes spike,envelope,membrane,nucleocapsid proteins,etc.(Phan 2020).These proteins are responsible for replicating the viral genome as well as generating nested transcripts that are used in the synthesis of the viral proteins. | Wei Chen Pengmian Feng Kewei Liu Meng Wu Hao Lin | 2020 | Virologica Sinica2020，35，3： | 2 |
| 3 | Robust Semi-nonnegative Matrix Factorization with Adaptive Graph Regularization for Gene Representation显示文摘Various data representation algorithms have been proposed for gene expression.There are some shor tcomings in tradi tio nal gene expression met hods,such as learning the ideal affinity matrix to effectively cap ture the geometric st rue ture of gene tic data space,and reducing noises and outliers influences of data input.We propose a novel matrix factorization algorithm called Robust semi-nonnegative matrix factorization(RSNMF)with adaptive graph regularization,which simultaneously performs matrix robust fhetorization with learning affinity matrix in a unified optimization framework.RSNMF also uses a loss function based on€2,i_norm to improve the robus tn ess of the model agains t noises and outliers.A novel Augmented Lagrange multiplier(ALM)is designed to obtain the optimal solution of RSNMF.The results of extensive experiments that were performed on gene expression datasets demonstrate that RSNMF out performs the ot her algori thms,which valida tes the effectiveness and robustness of RSNMF. | JIANG Wei MA Tingting FENG Xiaoting ZHAI Yun TANG Kewei ZHANG Jie | 2020 | Chinese Journal of Electronics2020，29，1： | 2 |
| 4 | Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors. | Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang | 2019 | Asian Journal of Urology2019，6，1： | 2 |

| 16 | A biodegradable magnesium surgical staple for colonic anastomosis: In vitro and in vivo evaluation显示文摘Staplers have been widely used in the clinical treatment of gastrointestinal reconstruction.However,the current titanium(Ti)staple will remain in the human body permanently,resulting in some adverse effects.In this study,we developed a type of biodegradable staple for colonic anastomosis using 0.3 mm diameter magnesium(Mg)alloy wires.The wire surface was modified by micro-arc oxidation treatment(MAO)and then coated with poly-L-lactic acid(PLLA)to achieve a moderate degradation rate matching the tissue healing process.The results of tensile tests on isolated porcine colon tissue anastomosed by Mg and Ti staples showed that the anastomotic property of Mg staples was almost equal to that of Ti staples.The in vitro degradation tests indicated the dual-layer coating effectively enhanced the corrosion resistance and maintained the tensile force of the coated staple stable after 14-day immersion in the simulated colonic fluid(SCF).Furthermore,24 beagle dogs were employed to conduct a comparison experiment using Mg-based and clinical Ti staples for 90-day implantation by ent-to-side anastomosis of the colon.The integrated structure of Mg-based staples was observed after 7 days and completely degraded after 90 days.All animals did not have anastomotic leakage and stenosis,and 12 dogs with Mg-based staples fully recovered after 90 days without differences in visceral ion levels and other side effects.The favorable performance makes this Mg-based anastomotic staple an ideal candidate for colon reconstruction. | Yue Zhang Jian Cao Mengmeng Lu Yi Shao Kewei Jiang Xiaodong Yang Xiaoyu Xiong Shan Wang Chenglin Chu Feng Xue Yingjiang Ye Jing Bai | 2023 | Bioactive Materials2023，，4： | 0 |

| 19 | 3D large-scale SPH modeling of vehicle wading with GPU acceleration显示文摘Vehicle wading is a complex fluid-structure interaction(FSI) problem and has attracted great attention recently from the automotive industry, especially for electric vehicles. As a meshless Lagrangian particle method, smoothed particle hydrodynamics(SPH) is one of the most suitable candidates for simulations of vehicle wading due to its inherent advantages in modeling free surface flows, splash, and moving interfaces. Nevertheless, the inevitable neighbor query for the nearest adjacent particles among the support domain leads to considerable computational cost and thus limits its application in 3D large-scale simulations. In this work, a GPU-based SPH method is developed with an adaptive spatial sort technology for simulations of vehicle wading. In addition, a fast, easy-to-implement particle generator is presented for isotropic initialization of the complex vehicle geometry with optimal interpolation properties. A comparative study of vehicle wading on a puddle between the GPUbased SPH with two pieces of commercial software is used to verify the capability of the GPU-based SPH method in terms of convergence analysis, kinematic characteristics, and computing performance. Finally, different conditions of vehicle speeds, water depths, and puddle widths are tested to investigate the vehicle wading numerically. The results demonstrate that the adaptive spatial sort technology can significantly improve the computing performance of the GPU-based SPH method and meanwhile promotes the GPU-based SPH method to be a competitive tool for the study of 3D large-scale FSI problems including vehicle wading. Some helpful findings of the critical vehicle speed, water depth as well as boundary wall effect are also reported in this work. | Huashan Zhang Xiaoxiao Li Kewei Feng Moubin Liu | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，10： | 0 |
