| 1 | Understanding environmental impacts on initial atmospheric corrosion based on corrosion monitoring sensors显示文摘Atmospheric corrosion monitoring(ACM)sensors were employed to study the initial atmospheric corrosion of carbon steels over a one-month period in six outdoor dynamic atmospheric environments in China.Based on the~250,000 corrosion data sets collected,the environmental impacts of relative humidity,temperature and rainfall on the initial corrosion behavior of carbon steels were investigated.The results showed that rainfall was the strongest environmental factor influencing the initial atmospheric corrosion rate.Relative humidity significantly influenced the corrosion of carbon steels in low-precipitation environments and non-rainfall period. | Zibo Pei Xuequn Cheng Xiaojia Yang Qing Li Chenhan Xia Dawei Zhang Xiaogang Li | 2021 | Journal of Materials Science & Technology2021，，5： | 12 |
| 2 | Percutaneous Ethanol Intratumoral Injection for Treatment of Small Primary Liver Cancer:Summary of 240 Cases显示文摘Objective To evaluate the therapeutic effects of percutaneous ethanol intratumoral injection(PETT) for treatment of small primary liver cancer(SPLC). Methods 240 patients with surgically or pathologically proved SPLC(<3 cm in diameter)were treated by PETT(under the guidance of B-ultrasound).Of the 240 patients ,163 had recurrent liver cancer,55 had inoperable liver cancer because of cardiac ,pulmonary ,hepat-ic and renal dydfunctions or due to the close proximity of trmor to the major vessels,and 22 refused to receive surgical resection.In 40 pa-tients who received surgical resection after PETT treatment, the resected tumors were pathologically evaluated for necrotic status and the pa-tients were followed up postoperatively.Results Postoperative1-,2- and 3-year survival rate of the 240 patients was 94.9%,84.2% and 66.3% respectively.Conclusion PETTcan be used as a non-invasive treatment for SPLC,and preoperative PETT appears to be helpful in reducing recurrence of postoperative liver cancer. | GUOJia CHENHan 等 | 2002 | The Chinese-German Journal of Clinical Oncology2002，1，2： | 4 |
| 3 | Resistance switching for RRAM applications显示文摘Resistive random access memory (RRAM or ReRAM) is a non-volatile memory (NVM) technology that consumes minimal energy while offering sub-nanosecond switching. In addition, the data stability against high temperature and cycling wear is very robust, allowing new NVM applications in a variety of markets (au- tomotive, embedded, storage, RAM). Based on sudden conduction through oxide insulators, the characteristics of RRAM technology have still yet to be fully described. In this paper, we present our current understanding of this very promising technology. | CHEN Frederick T LEE HengYuan CHEN YuSheng HSU YenYa ZHANG LiJie CHEN PangShiu CHEN WeiSu GU PeiYi LIU WenHsing WANG SuMin TSAI ChenHan SHEU ShyhShyuan TSAI MingJinn HUANG Ru | 2011 | Science China(Information Sciences)2011，54，5： | 3 |
| 4 | Real-time Bezier interpolation satisfying chord error constraint for CNC tool path显示文摘G01 code generated by a computer-aided manufacture(CAM) system is the most common form of tool trajectory in computer numerical control(CNC) machining. A tool path composed of short line segments has discontinuous tangency and curvature, generating large fluctuations of feedrate and acceleration, which in turn produces vibration in a machine tool. To obtain a smooth tool path, many methods on tool-path smoothing have been developed. However, the shortcomings in these methods exist when they are employed in a CNC system. It is difficult to simultaneously to guarantee the following requirements of CNC machining:(1) chord error should be rigidly constrained;(2) G01 points should be interpolated;(3) curvature should be continuous(G^2);(4) machining should be applicable to spatial cases;(5) real-time performance of computation is required. Based on these various requirements, this study proposes an interpolation scheme using cubic Bezier curves and includes an adjustment strategy to eliminate deficiencies in the tool path. The tool path generated is G^2, chord-error-constrained, G01-point-interpolated, loop-free, and optimized for both stretch and jerk energy. The method is applicable to 3D cases and involves only simple algebraic computations. Thus, the algorithm can be applied to real-time CNC machining. A simulation is conducted to validate the efficiency of the algorithm. In addition, an experiment reveals its advantage over Hermite interpolation in surface quality and machining efficiency. | FAN Wei LEE ChenHan CHEN JiHong XIAO Yao | 2016 | Science China(Technological Sciences)2016，59，2： | 3 |

| 7 | Challenges and future directions of secure federated learning:a survey显示文摘Federated learning came into being with the increasing concern of privacy security,as people’s sensitive information is being exposed under the era of big data.It is an algorithm that does not collect users’raw data,but aggregates model parameters from each client and therefore protects user’s privacy.Nonetheless,due to the inherent distributed nature of federated learning,it is more vulnerable under attacks since users may upload malicious data to break down the federated learning server.In addition,some recent studies have shown that attackers can recover information merely from parameters.Hence,there is still lots of room to improve the current federated learning frameworks.In this survey,we give a brief review of the state-of-the-art federated learning techniques and detailedly discuss the improvement of federated learning.Several open issues and existing solutions in federated learning are discussed.We also point out the future research directions of federated learning. | Kaiyue ZHANG Xuan SONG Chenhan ZHANG Shui YU | 2022 | Frontiers of Computer Science2022，16，5： | 1 |

| 11 | A novel phenotype of B cells associated with enhanced phagocytic capability and chemotactic function after ischemic stroke显示文摘Accumulating evidence has demonstrated the involvement of B cells in neuroinflammation and neuroregeneration.However,the role of B cells in ischemic stroke remains unclear.In this study,we identified a novel phenotype of macrophage-like B cells in brain-infiltrating immune cells expressing a high level of CD45.Macrophage-like B cells chara cterized by co-expression of B-cell and macrophage markers,showed stronger phagocytic and chemotactic functions compared with other B cells and showed upregulated expression of phagocytosis-related genes.Gene Ontology analysis found that the expression of genes associated with phagocytosis,including phagosome-and lysosome-related genes,was upregulated in macrophage-like B cells.The phagocytic activity of macrophage-like B cells was ve rified by immunostaining and three-dimensional reconstruction,in which TREM2-labeled macrophage-like B cells enwrapped and internalized myelin debris after cerebral ischemia.Cell-cell interaction analysis revealed that macrophage-like B cells released multiple chemokines to recruit peripheral immune cells mainly via CCL pathways.Single-cell RNA sequencing showed that the transdiffe rentiation to macrophage-like B cells may be induced by specific upregulation of the transcription factor CEBP fa mily to the myeloid lineage and/or by downregulation of the transcription factor Pax5 to the lymphoid lineage.Furthermore,this distinct B cell phenotype was detected in brain tissues from mice or patients with traumatic brain injury,Alzheimer’s disease,and glioblastoma.Overall,these results provide a new perspective on the phagocytic capability and chemotactic function of B cells in the ischemic brain.These cells may serve as an immunotherapeutic target for regulating the immune response of ischemic stroke. | Rui Wang Huaming Li Chenhan Ling Xiaotao Zhang Jianan Lu Weimin Luan Jianmin Zhang Ligen Shi | 2023 | Neural Regeneration Research2023，18，11： | 1 |

| 14 | A chemo-mechanical switchable valve on microfluidic chip based on a thermally responsive block copolymer显示文摘Microfluidic devices have become a powerful tool for chemical and biologic applications.To control different functional parts on the microchip,valve plays a key role in the device.In conventional methods,physio-mechanical valves are usually used on microfluidic chip.Herein,we reported a chemo-mechanical switchable valve on microfluidic chip by using a thermally responsive block copolymer.The wettability changes of capillary with copolymer modification on inner surface were investigated to verify the function as a valve.Capillaries with modification of poly-(N-isopropylacrylamide-co-hexafluoroisopropyl acrylate)(P(NIPAAm-co-HFIPA))with a 20%HFIPA was demonstrated capable of control aqueous solution stop or go through.Then short capillaries with copolymer modification were integrated in microchannels as valves.With the temperature changing around lower critical solution temperature(LCST),the integrated chemo-mechanical switchable valve exhibited excellent“OPEN–CLOSE”behavior for microflow control.After optimization of the block copolymer sequences and molar ratio,a switching time as low as 20 s was achieved.The developed micro valve was demonstrated effective for flow control on microchip. | Sifeng Mao Xiaohong Hu Yumi Tanaka Lin Zhou Chenhan Peng Nahoko Kasai Hizuru Nakajima Shungo Kato Katsumi Uchiyama | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
| 15 | The link between genetic variation and variability in vaccine responses:a narrative review显示文摘Vaccines are one of the biggest successes in modern history and are particularly important in light of the multiple ongoing epidemics.Recently,vaccines have protected peoples’health and lives around the world during the coronavirus disease 2019 pandemic.Different types of vaccines have their own characteristics and advantages and are used in the context of different epidemics.Responses to vaccination are also different,and can include adverse reactions and absent responses.These individual differences are thought to be influenced by host genes.In this review,we first discuss vaccine types and characteristics.Second,we discuss different responses to vaccination,primarily focusing on the association between genetic variation and inter-individual differences. | Yingtian Zhang Mingzhe Zhao Wei Zhou Luan Chen Mo Li Bixuan Jiang Xianglong Zhao Hao Wu Lu Shen Na Zhang Hengwei Qin Yuhao Tang Chenhan Jiad Lin He Shengying Qin | 2022 | Journal of Bio-X Research2022，5，2： | 0 |
| 16 | Judgement on Extended Hepatectomy for Primary Liver Cancer显示文摘Objective: To expore the indications and safety of extended hepatectomy for primary liver cancer (PLC). Methods: From Nov. 2000 to Oct. 2002, 33 patients with PLC received extended hepatectomy, 26 of whom were complicated with liver cirrhosis. Preoperative findings, intraoperative management and the outcome of postoperative recovery were analyzed and evaluated. Results: Operative mortality was zero in this group and postoperative morbidity of complications was 33.3%, and all complications were cured after proper treatment. Conclusion: Extended hepatectomy for PLC was safe and viable for the patients who had enough reserve of liver function if the incised liver volume was less than 50% of the liver and the supporting treatment of the remnant liver was given as well as the postoperative complications were managed appropriately. | YANGJiamei TONGYing CHENHan XUFeng KANTong WUMengchao | 2003 | The Chinese-German Journal of Clinical Oncology2003，2，3： | 0 |
