| 1 | A male-ABCD algorithm for hepatocellular carcinoma risk prediction in HBs Ag carriers显示文摘Objective: Hepatocellular carcinoma(HCC) development among hepatitis B surface antigen(HBs Ag) carriers shows gender disparity, influenced by underlying liver diseases that display variations in laboratory tests. We aimed to construct a risk-stratified HCC prediction model for HBs Ag-positive male adults.Methods: HBs Ag-positive males of 35-69 years old(N=6,153) were included from a multi-center populationbased liver cancer screening study. Randomly, three centers were set as training, the other three centers as validation. Within 2 years since initiation, we administrated at least two rounds of HCC screening using Bultrasonography and α-fetoprotein(AFP). We used logistic regression models to determine potential risk factors,built and examined the operating characteristics of a point-based algorithm for HCC risk prediction.Results: With 2 years of follow-up, 302 HCC cases were diagnosed. A male-ABCD algorithm was constructed including participant's age, blood levels of GGT(γ-glutamyl-transpeptidase), counts of platelets, white cells,concentration of DCP(des-γ-carboxy-prothrombin) and AFP, with scores ranging from 0 to 18.3. The area under receiver operating characteristic was 0.91(0.90-0.93), larger than existing models. At 1.5 points of risk score,26.10% of the participants in training cohort and 14.94% in validation cohort were recognized at low risk, with sensitivity of identifying HCC remained 100%. At 2.5 points, 46.51% of the participants in training cohort and 33.68% in validation cohort were recognized at low risk with 99.06% and 97.78% of sensitivity, respectively. At 4.5 points, only 20.86% of participants in training cohort and 23.73% in validation cohort were recognized at high risk,with positive prediction value of 22.85% and 12.35%, respectively.Conclusions: Male-ABCD algorithm identified individual's risk for HCC occurrence within short term for their HCC precision surveillance. | Yuting Wang Minjie Wang He Li Kun Chen Hongmei Zeng Xinyu Bi Zheng Zhu Yuchen Jiao Yong Wang Jian Zhu Hui Zhao Xiang Liu Chunyun Dai Chunsun Fan Can Zhao Deyin Guo Hong Zhao Jianguo Zhou Dongmei Wang Zhiyuan Wu Xinming Zhao Wei Cui Xuehong Zhang Jianqiang Cai Wanqing Chen Chunfeng Qu | 2021 | Chinese Journal of Cancer Research2021，33，3： | 3 |
| 2 | Corrosion and aging of organic aviation coatings:A review显示文摘Organic anticorrosive aviation coatings are an effective guarantee for aviation structure,since aircraft corrosion can lead to great economic losses.Whether it is during ground parking or air cruises,organic aviation coatings are important barriers to the corrosion of aviation structure.With the vigorous development of the aviation industry,organic aviation coatings continue to meet the challenges of diverse,complex,and harsh service environments.This review analyzes and summarizes the research status of the types and development of organic aviation coatings,influencing factors and mechanisms,experimental methods,calendar life research methods,and modification methods.It also summarizes the research results that have been achieved to date.The current research deficiencies in the equivalence relationship between atmospheric exposure and artificial acceleration,failure criteria and life prediction were pointed out,and nano-modification technology,and future research strategies and directions that need breakthroughs are discussed. | Tianyu ZHANG Teng ZHANG Yuting HE Yuchen WANG Yaping BI | 2023 | Chinese Journal of Aeronautics2023，36，4： | 2 |

| 4 | Interconnected N/P co-doped carbon nanocage as high capacitance electrode material for energy storage devices显示文摘Heteroatom doping carbon materials exhibit a huge application potential for energy storage devices(ESDs).Herein,interconnected N/P co-doped carbon nanocage(NP-CNC)was synthesized from pyrene molecules by using nano-MgO as template and melamine-phytic acid supramolecular aggregate as dopant coupled with KOH activation.The as-prepared NP-CNC possesses interconnected nanocages for electron transportation and abundant micropores for ion adsorption.Moreover,co-doped N/P species in NP-CNC provide active sites and additional pseudocapacitance.Consequently,NP-CNC as electrode material for symmetric supercapacitor exhibits a high gravimetric capacitance of 435 F·g^(-1) at 0.05 A·g^(-1),high volumetric capacitance of 274 F·cm^(-3) at 0.032 A·cm^(-3),and long cycle lifespan with 96.1%capacitance retention after 50,000 cycles.Furthermore,NP-CNC as cathode for zinc-ion hybrid supercapacitor delivers satisfactory energy and power densities of 130.6 Wh·kg^(-1)(82.3 Wh·L^(-1))and 14.4 kW·kg^(-1)(9.1 kWL^(-1)).This work paves a promising approach to the preparation of high capacitance NP-CNC for ESDs. | Lei Yang Xiaojun He Yuchen Wei Honghui Bi Feng Wei Hongqiang Li Changzhou Yuan Jieshan Qiu | 2022 | Nano Research2022，15，5： | 1 |
| 5 | Low-thermal-budget Au-free ohmic contact to an ultrathin barrier AlGaN/GaN heterostructure utilizing a micro-patterned ohmic recess显示文摘A pre-ohmic micro-patterned recess process,is utilized to fabricate Ti/Al/Ti/TiN ohmic contact to an ultrathin-barrier(UTB)AlGaN/GaN heterostructure,featuring a significantly reduced ohmic contact resistivity of 0.56Ω·mm at an alloy temperature of 550℃.The sheet resistances increase with the temperature following a power law with the index of +2.58,while the specific contact resistivity decreases with the temperature.The contact mechanism can be well described by thermionic field emission(TFE).The extracted Schottky barrier height and electron concentration are 0.31 eV and 5.52×10^(18) cm^(−3),which suggests an intimate contact between ohmic metal and the UTB-AlGaN as well as GaN buffer.A good correlation between ohmic transfer length and the micro-pattern size is revealed,though in-depth investigation is needed.A preliminary CMOS-process-compatible metal-insulator-semiconductor high-mobility transistor(MIS-HEMT)was fabricated with the proposed Au-free ohmic contact technique. | Wen Shi Sen Huang Xinhua Wang Qimeng Jiang Yixu Yao Lan Bi Yuchen Li Kexin Deng Jie Fan Haibo Yin Ke Wei Yankui Li Jingyuan Shi Haojie Jiang Junfeng Li Xinyu Liu | 2021 | Journal of Semiconductors2021，42，9： | 0 |
