1High-Efficiency Electromagnetic Interference Shielding of rGO@FeNi/Epoxy Composites with Regular Honeycomb Structures显示文摘With the rapid development of fifth-generation mobile com-munication technology and wearable electronic devices,electromagnetic interference and radiation pollution caused by electromagnetic waves have attracted worldwide attention.Therefore,the design and development of highly efficient EMI shielding materials are of great importance.In this work,the three-dimensional graphene oxide(GO)with regular honeycomb structure(GH)is firstly constructed by sacrificial template and freeze-dry-ing methods.Then,the amino functionalized FeNi alloy particles(f-FeNi)are loaded on the GH skeleton followed by in-situ reduction to prepare rGH@FeNi aerogel.Finally,the rGH@FeNi/epoxy EMI shielding com-posites with regular honeycomb structure is obtained by vacuum-assisted impregnation of epoxy resin.Benefitting from the construction of regular honeycomb structure and electromagnetic synergistic effect,the rGH@FeNi/epoxy composites with a low rGH@FeNi mass fraction of 2.1 wt%(rGH and f-FeNi are 1.2 and 0.9 wt%,respectively)exhibit a high EMI shielding effectiveness(EMI SE)of 46 dB,which is 5.8 times of that(8 dB)for rGO/FeNi/epoxy composites with the same rGO/FeNi mass fraction.At the same time,the rGH@FeNi/epoxy composites also possess excellent thermal stability(heat-resistance index and temperature at the maximum decomposition rate are 179.1 and 389.0°C respectively)and mechanical properties(storage modulus is 8296.2 MPa).Ping Song Zhonglei Ma Hua Qiu Yifan Ru Junwei Gu 2022Nano-Micro Letters2022,14,3:13

7Thrombin Generation Increasing with Age and Decreasing with Use of Heparin Indicated by Calibrated Automated Thrombogram Conducted in Chinese显示文摘Objective Calibrated Automated Thrombogram(CAT) is a test to monitor the generation of thrombin. It can be described by four parameters: lag time, peak thrombin, endogenous thrombin potential(ETP) and time to peak(ttPeak). This study aims to determine the normal ranges of CAT parameters in Chinese, and evaluate whether thrombin generation is correlated with the concentration of heparin/low molecular weight heparin. Methods Plasma from 120 healthy subjects were collected to determine the normal rangea of CAT parameters in Chinese. Normal plasma pool(NPP, n=25) spiked with different concentrations of heparin or enoxaparin were used to detecte CAT parameters. The overall and age specific normal ranges of CAT parameters were calculated using descriptive statistics method with mean±2SD. The correlation between CAT parameters and age or concentrations of heparin, enoxaparin were analyzed with linear regression model. Results The normal ranges for lag time, peak thrombin, ETP, ttPeak in the subjects were 3.648±2.465 min, 367.39±151.93 nmol/L, 2277±1030 nmol/L·min and 6.372±4.280 min respectively. Age was linearly correlated with lag time(r=-0.6583, P<0.0001), peak thrombin(r=0.4863, P<0.0001), ETP(r=0.3608, P<0.0014) and ttPeak(r=-0.6313, P<0.0001). The values of ETP/peak ratio were linearly correlated with concentrations of heparin. Conclusion The normal ranges of four CAT parameters for Chinese were determined. CAT parameters are associated with age. ETP/peak ratio could be used to monitor the process of anticoagulation therapy.WU Jun ZHAO Hui Ru ZHANG Hui Ying GE Yan Ling QIU Shuang ZHAO Jie SONG Ying ZHAO Jing Zhong LU Song Song 2014Biomedical and Environmental Sciences2014,27,5:2

9NA-CPG: A robust and stable rhythm generator for robot motion control显示文摘Central pattern generators(CPGs)have been widely applied in robot motion control for the spontaneous output of coherent periodic rhythms.However,the underlying CPG network exhibits good convergence performance only within a certain range of parameter spaces,and the coupling of oscillators affects the network output accuracy in complex topological relationships.Moreover,CPGs may diverge when parameters change drastically,and the divergence is irreversible,which is catastrophic for the control of robot motion.Therefore,normalized asymmetric CPGs(NA-CPGs)that normalize the amplitude parameters of Hopf-based CPGs and add a constraint function and a frequency regulation mechanism are proposed.NA-CPGs can realize parameter decoupling,precise amplitude output,and stable and rapid convergence,as well as asymmetric output waveforms.Thus,it can effectively cope with large parameter changes to avoid network oscillations and divergence.To optimize the parameters of the NA-CPG model,a reinforcement-learning-based online optimization method is further proposed.Meanwhile,a biomimetic robotic fish is illustrated to realize the whole optimization process.Simulations demonstrated that the designed NA-CPGs exhibit stable,secure,and accurate network outputs,and the proposed optimization method effectively improves the swimming speed and reduces the lateral swing of the multijoint robotic fish by 6.7%and 41.7%,respectively.The proposed approach provides a significant improvement in CPG research and can be widely employed in the field of robot motion control.Ru Tong Changlin Qiu Zhengxing Wu Jian Wang Min Tan Junzhi Yu 2022Biomimetic Intelligence & Robotics2022,2,4:1
10Comparable outcomes but higher risks of prolonged viral RNA shedding duration and secondary infection in cancer survivors with COVID-19: A multi-center, matched retrospective cohort study显示文摘Results Sixty-one cancer survivors and 183 matched non-cancer patients were screened from 2,828 COVID-19 infected patients admitted to 4 hospitals in Wuhan,China.The median ages of the cancer survivor cohort and non-cancer patient cohort were 64.0(55.0–73.0)and 64.0(54.0–73.5),respectively(P=0.909).Cancer survivors reported a higher incidence of symptom onset than non-cancer patients.Fever(80.3%vs.65.0%;P=0.026)was the most prevalent symptom,followed by cough(65.6%vs.37.7%;P<0.001),myalgia,and fatigue(45.9%vs.13.6%;P<0.001).The risks of the development of severe events(adjusted hazard ratio[AHR]=1.25;95%confidence interval[CI]:0.76–2.06;P=0.378)and mortality(relative risk[RR]=0.90,95%CI:0.79–1.04;P=0.416)in the cancer survivor cohort were comparable to those of the matched non-cancer patient cohort.However,the cancer survivor cohort showed a higher incidence of secondary infection(52.5%vs.30.1%;RR=1.47,95%CI:1.11–1.95;P=0.002)and a prolonged viral RNA shedding duration(32 days[IQR 26.0–46.0]vs.24.0 days[IQR 18.0–33.0];AHR=0.54;95%CI:0.38–0.80;P<0.05).Conclusion Compared to non-cancer patients,cancer survivors with COVID-19 exhibited a higher incidence of secondary infection,a prolonged period of viral shedding,but comparable risks of the development of severe events and mortality.It is helpful for clinicians to take tailored measures to treat cancer survivors with COVID-19.Hui Peng Sheng Wang Qi Mei Yuhong Dai Jian Li Ming Li Kathrin Halfter Xueyan Jiang Qin Huang Lei Wang Wei Wei Ru Liu Zhen cao Motuma Yigezu Daba Fangfang Wang Bingqing Zhou Hong Qiu Xianglin Yuan 2020Oncology and Translational Medicine2020,6,6:1

15MXenes nanocomposites for energy storage and conversion显示文摘The development of two-dimensional(2 D)high-performance electrode materials is the key to new advances in the fields of energy storage and conversion.As a novel family of 2 D layered materials,MXenes possess distinct structural,electronic and chemical properties that enable vast application potential in many fields,including batteries,supercapacitor and catalysis.However,MXene layers are easily formed by stacking together,which significantly reduces the specific surface area,hinders the transmission of ions,and restricts other functional materials on the surface,thereby reducing performance.In addition,due to the inherent defects of a single electrode material,electrodes or catalysts made of single-phase MXene may not meet specific practical application requirements.MXenes nanocomposites materials based on enhanced electrochemical performance through nanoengineering technology and surface modification for morphological control are highly sought after to solve these challenges.This review aims to present recent advances in these emerging MXene nanocomposites for energy storage and conversion applications such as batteries,supercapacitors and catalytic reactions.We also introduced some of the challenges and opportunities in this rapidly developing field.Zi-Ming Qiu Yang Bai Yi-Dan Gao Chun-Li Liu Yue Ru Ye-Can Pi Yi-Zhou Zhang Yong-Song Luo Huan Pang 2022Rare Metals2022,41,4:1
