| 1 | Efficacy of Chinese herbal medicine for lumbar disc herniation: a systematic review of randomized controlled trials显示文摘OBJECTIVE: This is a review of the effects of Chinese herbal medicine(CHM) used alone to treat lumbar disc herniation(LDH). METHORDS: A literature search of the following electronic databases from their inception to February 2013 was conducted: Chinese Biomedical databases, Chinese National Knowledge Infrastructure, Wanfang Database, China Science and Technology Journal Database, Cochrane Library, Web of Science, MEDLINE, and EMBASE. Randomized controlled trials where CHM had been used to treat LDH were selected. Data extraction, quality assessment, and data analysis were carried out by two independent reviewers. RESULTS: Of the 2415 studies identified, eight with complete data on 1146 patients were selected. The methodological quality was poor in all trials. Five studies reported that CHM was better than Western Medicine [OR=2.81, 95% CI(1.27, 6.18); OR=3.34, 95% CI(1.92, 5.79); OR=2.22, 95% CI(1.08, 4.57); OR= 6.67, 95% CI(1.34, 33.28); and OR=1.94, 95% CI(1.23, 3.06)]. Two studies reported that the clinical outcome was better in CHM groups than in physiotherapy and placebo groups, [OR=3.02, 95% CI(1.08, 8.46); and OR=2.67, 95% CI(1.26, 5.64), respectively], whereas one study reported no difference between CHM and physiotherapy groups. One study reported that CHM resulted in higher Japanese Orthopedic Association scores [MD=7.78, 95% CI(6.67, 8.89)] than in a control group and another that participants treated with CHM had lower Visual Analogue Scale scores [MD=﹣0.72, 95% CI( ﹣0.86, ﹣0.58)] than those in a control group. Three studies reported that the adverse effects of CHM and Western Medicine did not differ significantly [OR=0.10, 95% CI(0.01, 1.85); OR=0.19, 95% CI(0.01, 4.07); and OR=0.07, 95% CI(0.00, 1.32)]. CONCLUSION: CHM may be more effective than other interventions for LDH; however, methodological weaknesses in the studies assessed in this review prevent a definitive conclusion. More high-quality large-scale studies are required to clarify this matter. | Yi Luo Jian Huang Lin Xu Weikang Zhao Jie Hao Zhenming Hu | 2013 | Journal of Traditional Chinese Medicine2013，33，6： | 15 |
| 2 | Effect of Sn addition on the mechanical properties and bio-corrosion behavior of cytocompatible Mg-4Zn based alloys显示文摘The mechanical properties and bio-corrosion behaviors of as-extruded Mg-4Zn alloys after Sn addition were investigated,systemati-cally.A small amount of Sn addition to Mg-4Zn alloy slightly improved the mechanical properties for solid solution strengthening,and significantly controlled the bio-corrosion rates.Sn participating in the outer layer film formation as SnO/SnO_(2)resisted the bio-corrosion proceeding.Especially,Mg-4Zn-1.5Sn alloy,with a weight loss rate of 0.45 mm/y and hydrogen evolution rate of 0.099 mL/cm^(2)/day,showed cytotoxicity grade of 0 to MC3T3-E1 cells.The perfect alliance of cytocompatibility,suitable mechanical properties and low bio-corrosion rate demonstrates that this Mg-4Zn-1.5Sn alloy is a promising biodegradable magnesium alloy for orthopedic implants. | Weiyan Jiang Jingfeng Wang Weikang Zhao Qingshan Liu Dianming Jiang Shengfeng Guo | 2019 | Journal of Magnesium and Alloys2019，7，1： | 6 |
| 3 | A novel biodegradable Mg-1Zn-0.5Sn alloy:Mechanical properties,corrosion behavior,biocompatibility,and antibacterial activity显示文摘To meet the growing demand for antibacterial implants for bone-implant-associated infection therapy and avoid the adverse effects of secondary surgery,a degradable platform with pH responsiveness and ion-associated antibacterial properties was constructed.A small amount of Sn added to Mg-1Zn alloy reduces the biocorrosion rate,which can be attributed to Sn participation in outer-layer film formation,significantly reducing the biocorrosion rate and hydrogen evolution rate after implantation in vivo.These Mg alloys,which are susceptible to degradation in the acidic bacterial microenvironment,degrade by releasing Mg,Zn and Sn,producing favorably alkaline and antibacterial conditions.Samples with the composition of Mg-1Zn-0.5Sn were found to be beneficial for promoting initial cell adhesion and proliferation,resulting in improved biocompatibility and biosafety.The biocompatibility of this alloy was confirmed by the healthy behavior of animals and the absence of acute or chronic toxicity in the liver,spleen,and kidneys.Our results demonstrate that Mg-1Zn-0.5Sn is safe for biological systems,enabling its efficacious use in biomedical applications. | Weikang Zhao Jingfeng Wang Jiang Weiyang Bo Qiao Yiyang Wang Yuling Li Dianming Jiang | 2020 | Journal of Magnesium and Alloys2020，8，2： | 3 |
| 4 | Improving in vitro and in vivo corrosion resistance and biocompatibility of Mg-1Zn-1Sn alloys by microalloying with Sr显示文摘Magnesium(Mg)and its alloys have attracted attention as potential biodegradable materials in orthopedics due to their mechanical and physical properties,which are compatible with those of human bone.However,the effect of the mismatch between the rapid material degradation and fracture healing caused by the adverse effect of hydrogen(H2),which is generated during degradation,on surrounding bone tissue has severely restricted the application of Mg and its alloys.Thus,the development of new Mg alloys to achieve ideal degradation rates,H2 evolution and mechanical properties is necessary.Herein,a novel Mg-1Zn-1Sn-xSr(x=0,0.2,0.4,and 0.6 wt%)quaternary alloy was developed,and the microstructure,mechanical properties,corrosion behavior and biocompatibility in vitro/vivo were investigated.The results demonstrated that a minor amount of strontium(Sr)(0.2 wt%)enhanced the corrosion resistance and mechanical properties of Mg-1Zn-1Sn alloy through grain refinement and second phase strengthening.Simultaneously,due to the high hydrogen overpotential of tin(Sn),the H2 release of the alloys was significantly reduced.Furthermore,Sr-containing Mg-1Zn-1Sn-based alloys significantly enhanced the viability,adhesion and spreading of MC3T3-E1 cells in vitro due to their unique biological activity and the ability to spontaneously form a network structure layer with micro/nanotopography.A low corrosion rate and improved biocompatibility were also maintained in a rat subcutaneous implantation model.However,excessive Sr(>0.2 wt%)led to a microgalvanic reaction and accelerated corrosion and H2 evolution.Considering the corrosion resistance,H2 evolution,mechanical properties and biocompatibility in vitro and in vivo,Mg-1Zn-1Sn-0.2Sr alloy has tremendous potential for clinical applications. | Yafeng Wen Qingshan Liu Jingfeng Wang Qiming Yang Weikang Zhao Bo Qiao Yuling Li Dianming Jiang | 2021 | Bioactive Materials2021，6，12： | 3 |
| 5 | PbMC1a/1b regulates lignification during stone cell development in pear(Pyrus bretschneideri)fruit显示文摘Programmed cell death(PCD)and secondary cell wall(SCW)thickening in pear fruit are accompanied by the deposition of cellulose and lignin to form stone cells.Metacaspase is an important protease for development,tissue renewal and PCD.The understanding of the molecular mechanism whereby pear(Pyrus)metacaspase promotes PCD and cell wall lignification is still limited.In this study,the Metacaspases gene family(PbMCs)from P.bretschneideri was identified.PbMC1a/1b was associated with lignin deposition and stone cell formation by physiological data,semiquantitative real-time polymerase chain reaction(RT-PCR)and quantitative RT-PCR(qRT-PCR).Relative to wildtype(WT)Arabidopsis,the overexpression of PbMC1a/1b increased lignin deposition and delayed growth,thickened the cell walls of vessels,xylary fibers and interfascicular fibers,and increased the expression of lignin biosynthetic genes.Yeast two-hybrid(Y2H),bimolecular fluorescence complementation(BiFC)and GST pull-down assays indicated that the PbMC1a/1b protein physically interacted with PbRD21.Simultaneously,the transient expression of PbMC1a/1b and PbRD21 led to significant changes in the expression of genes and lignin contents in pear fruits and flesh calli.These results indicate that PbMC1a/1b plays an important role in cell wall lignification,possibly by interacting with PbRD21 to increase the mRNA levels of some lignin synthesis-associated genes and promote the formation of stone cells in pear fruit. | Xin Gong Zhihua Xie Kaijie Qi Liangyi Zhao Yazhou Yuan Jiahui Xu Weikang Rui Katsuhiro Shiratake Jianping Bao Shahrokh Khanizadeh Shaoling Zhang Shutian Tao | 2020 | Horticulture Research2020，7，1： | 3 |
| 6 | Recent advances in nonlinear optical rare earth structures显示文摘Nonlinear optical(NLO)crystals can be employed to expand the laser frequency and thus are of technical importance in advanced laser science.Noncentrosymmetric rare earth compounds keep attracting broad interest as a significant branch of NLO materials because the highly distorted structural motifs centered by rare earth ions could remarkably benefit the second harmonic generation.In this review,we proceed from structure-properties relationship and reveal the role of rare earth element in the optical properties of NLO materials.We believe that this work can deepen the understanding of rare earth-based NLO materials and provide some enlightenment for exploring novel practical NLO crystals. | Jun Zhao Dajiang Mei Weikang Wang Yuandong Wu Dongfeng Xue | 2021 | Journal of Rare Earths2021，39，12： | 3 |
| 7 | Control measures during the COVID-19 outbreak reduced the transmission of hand,foot,and mouth disease显示文摘Control measures during the coronavirus disease 2019(COVID-19)outbreak may have limited the spread of infectious diseases.This study aimed to analyze the impact of COVID-19 on the spread of hand,foot,and mouth disease(HFMD)in China.A mathematical model was established to fit the reported data of HFMD in six selected cities in China's Mainland from 2015 to 2020.The absolute difference(AD)and relative difference(RD)between the reported incidence in 2020,and simulated maximum,minimum,or median incidence of HFMD in 2015-2019 were calculated.The incidence and R effof HFMD have decreased in six selected cities since the outbreak of COVID-19,and in the second half of 2020,the incidence and R effof HFMD have rebounded.The results show that the total attack rate(TAR)in 2020 was lower than the maximum,minimum,and median TAR fitted in previous years in six selected cities(except Changsha City).For the maximum,median,minimum fitted TAR,the range of RD(%)is 42·20-99·20%,36·35-98·41%48·35-96·23%(except Changsha City)respectively.The preventive and control measures of COVID-19 have significantly contributed to the containment of HFMD transmission. | Yan Niu Li Luo Jia Rui Shiting Yang Bin Deng Zeyu Zhao Shengnan Lin Jingwen Xu Yuanzhao Zhu Yao Wang Meng Yang Xingchun Liu Tianlong Yang Weikang Liu Peihua Li Zhuoyang Li Chan Liu Jiefeng Huang Tianmu Chen | 2021 | Journal of Safety Science and Resilience2021，2，2： | 3 |
| 8 | Feasibility of Booster Vaccination in High-Risk Populations for Controlling Coronavirus Variants—China,2021显示文摘Introduction:Vaccination booster shots are completely necessary for controlling breakthrough infections of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in China.The study aims to estimate effectiveness of booster vaccines for high-risk populations(HRPs).Methods:A vaccinated Susceptible-Exposed-Symptomatic-Asymptomatic-Recovered/Removed(SEIAR)model was developed to simulate scenarios of effective reproduction number(Reff)from 4 to 6.Total number of infectious and asymptomatic cases were used to evaluated vaccination effectiveness.Results:Our model showed that we could not prevent outbreaks when covering 80%of HRPs with booster unless Reff=4.0 or the booster vaccine had efficacy against infectivity and susceptibility of more than 90%.The results were consistent when the outcome index was confirmed cases or asymptomatic cases.Conclusions:An ideal coronavirus disease 2019(COVID-19)booster vaccination strategy for HRPs would be expected to reach the initial goal to control the transmission of the Delta variant in China.Accordingly,the recommendation for the COVID-19 booster vaccine should be implemented in HRPs who are already vaccinated and could prevent transmission to other groups. | Kangguo Li Zeyu Zhao Hongjie Wei Jia Rui Jiefeng Huang Xiaohao Guo Yichao Guo Shiting Yang Guzainuer Abudurusuli Li Luo Xingchun Liu Yao Wang Jingwen Xu Yuanzhao Zhu Meng Yang TianlongYang Weikang Liu Bin Deng Chan Liu Zhuoyang Li Peihua Li Shanshan Yu Zimei Yang Yanhua Su Benhua Zhao Yan Niu Tianmu Chen | 2021 | China CDC weekly2021，3，50： | 2 |

| 10 | Rare-Earth Metal Alkyl Complexes with 3-Arylamido-Functionalized Indolyl Ligands:Synthesis,Characterization and Reactivity显示文摘A series of dinuclear rare-earth metal alkyl complexes{[μ-η^2:η^1:η^1-3-(LNCH)(CH2SiMe3)Ind]RE-(CH2SiMe3)(THF)}2(L^1=2-tBuC6H4,RE=Y,Gd,Dy,Er,Yb;L^2=2,4,6-Me3C6H2,RE=Dy,Er;Ind=indolyl)and{[μ-η^2:η^1:η^1-3-(LNCH2)Ind]RE(CH2SiMe3)(THF)}2(L^1,RE=Y,Dy,Er,Yb;L^2,RE=Er,Yb)bearing 3-arylamido functionalized indolyl ligands having diverse bonding modes with metal ions were synthesized either by the insertion reaction of the imino group to the RE-C bond or by the alkane elimination reaction.In the preparation of above complexes,rare-earth metal alkyl complexes{[μ-η^5:η^1:η^1-3-(L^2 NCH)(CH2SiMe3)Ind]Gd(CH2SiMe3)(THF)}2 with aμ-η^5:η^1:η^1 coordination mode to the gadolinium ion and{[μ-η^3:η^1:η^1-3-(L^2NCH2)Ind]Dy(CH2SiMe3)(THF)}2 with aμ-η^3:η^1:η^1 coordination mode to the dysprosium ion were unexpectedly isolated.The reactions of 3-(L^2N=CH)lnd with Er(CH2SiMe3)3(THF)2 at room temperature,generated a tetranuclear imino-indolyl erbium intermediate{[μ-η^1:η^1-3-(L^2N=CH)Ind]Er(CH2SiMe3)2(THF)}4,which can transform into the amido functionalized indolyl erbium complex in hot toluene.Moreover,the reactivities of the newly synthesized ytterbium complex with N-heterocyclic compounds were investigated,affording the corresponding products of the mixed pyridyl-indolyl,imidazolyl-indolyl,and ortho-metalated complexes.The yttrium complexes showed a high regioselectivity and steroselectivity for the isoprene polymerization with 1,4-trans selectivity up to 91.7%and 1,4-cis selectivity up to 96.1%in the presence of cocatalysts,respectively. | Xiancui Zhu Yuzhe Jiang Jun Chen Shaowu Wang Zeming Huang Shan Zhu Xu Zhao Wenrun Yue Jun Zhang Weikang Wu Xiangyang Zhong | 2020 | Chinese Journal of Chemistry2020，38，5： | 1 |

| 12 | Experimental and Theoretical Studies of C_(3)F_(7)CN/CO_(2) Mixture Decomposition Under Overheating Fault显示文摘Heptafluoroisobutyrontrile(C_(3)F_(7)CN)performs well in dielectric properties and environmental protection,which has the potential to replace SF6 gas.The decomposition characteristics of C_(3)F_(7)CN mixture under fault conditions directly affect the possibility of its replacement for SF6 gas.However,the number of studies on the decomposition characteristics of C_(3)F_(7)CN mixture under overheating fault is less.In this paper,the decomposition characteristics of C_(3)F_(7)CN/CO_(2) mixture under an overheating fault are studied by gas chromatography-mass spectrometry(GC/MS)and quantum chemical calculations.Byproducts CO,C_(3)F_(6) and HF are detected at 200℃.At 550℃,the C_(3)F_(7)CN molecule begins to decompose and produces CHF_(3),C_(2)F_(4),CF_(3)CN and CNCN.Moreover,the results of GC/MS show that the insulation medium C_(3)F_(7)CN contains an impurity,which is C3HF7(HFC-227ea).Combined with the results of GC/MS and quantum chemistry calculations,it can be concluded that the decomposition by-product C_(3)F_(6) at 200℃ mainly comes from the decomposition of C_(3)HF_(7).C_(3)HF_(7) reduces the decomposition temperature of the C_(3)F_(7)CN/CO_(2) mixture.Therefore,it is very important to improve the purity of the insulation medium C_(3)F_(7)CN. | Mingyue Zhao Dong Han Weikang Zhao Zhenrui Zhou Guoqiang Zhang | 2022 | CSEE Journal of Power and Energy Systems2022，8，3： | 1 |
| 13 | Vascular Endothelial Growth Factor‑Recruiting Nanofiber Bandages Promote Multifunctional Skin Regeneration via Improved Angiogenesis and Immunomodulation显示文摘Tissue injury leads to gradients of chemoattractants,which drive multiple processes for tissue repair,including the inflam-matory response as well as endogenous cell recruitment.However,a limited time window for the gradients of chemoattract-ants as well as their poor stability at the injury site may not translate into healthy tissue repair.Consequently,intelligent multifunctional scaffolds with the capability to stabilize injury-induced cytokines and chemokines hold great promise for tissue repair.Vascular endothelial growth factor(VEGF)plays a significant role in wound healing by promoting angiogen-esis.The overarching objective of this research was to develop intelligent multifunctional scaffolds with the capability to endogenously recruit VEGF and promote wound healing via angiogenic and immunomodulatory dual functions.Prominin-1-derived peptide(PR1P)was encapsulated into electrospun poly(L-lactide-coglycolide)/gelatin(P/G)-based bandages.The sustained release of PR1P recruited VEGF in situ,thereby stabilizing the protein concentration peak in vivo and affording a reparative microenvironment with an adequate angiogenic ability at the wound site.Meanwhile,PR1P-recruited VEGF-induced macrophage reprogramming towards M2-like phenotypes further conferred immunomodulatory functions to the bandages.These dual functions of proangiogenesis and immunomodulation formed a cascade amplification,which regulated matrix metalloproteinases(MMP-9)as well as inflammatory factors(nuclear factor(NF)-κb,tumor necrosis factor(TNF)-α)in the wound microenvironment via the VEGF/macrophages/microenvironment axis.Consequently,the bandages realized multifunctional regeneration in splinted excisional wounds in rats,with or without diabetes,affording a higher skin append-age neogenesis,sensory function,and collagen remodeling.Conclusively,our approach encompassing in situ recruitment of VEGF at the injury site with the capability to promote immunomodulation-mediated tissue repair affords a promising avenue for scarless wound regeneration,which may also have implications for other tissue engineering disciplines. | Yi Chen Zhengchao Yuan Weiyan Sun Muhammad Shafiq Jun Zhu Jiafei Chen Hai Tang Ling Hu Weikang Lin Yanxi Zeng Long Wang Lei Zhang Yunlang She Hui Zheng Guofang Zhao Dong Xie Xiumei Mo Chang Chen | 2023 | Advanced Fiber Materials2023，5，1： | 1 |
| 14 | Federated learning-based short-term building energy consumption prediction method for solving the data silos problem显示文摘Transfer learning is an effective method to predict the energy consumption of information-poor buildings by learning transferable knowledge from operational data of information-rich buildings.However,it is not recommended to directly use the operational data without protection due to the risk of leaking occupants’privacy.To address this problem,this study proposes a federated learning-based method to learn transferable knowledge from building operational data without privacy leaking.It trains a transferable federated model based on the operational data from the buildings similar to the target building with limited data.An advanced secure aggregation algorithm is adopted in the training process to ensure that no one can infer private information from the training data.The federated model obtained is evaluated by comparing it with the standalone model without federated learning based on 13 similar office buildings from the Building Data Genome Project.The results show that the federated model outperforms the standalone model concerning the prediction accuracy and training time.On average,the federated model achieves a 25.4%decrease in CV-RMSE when the target building has limited operational data.Even if the target building has no operational data,the federated model still achieves acceptable accuracy(CV-RMSE is 22.2%).Meanwhile,the training time of the federated model is 90%less than that of the standalone model.The research insights can help develop federated learning-based methods for solving the data silos problem in building energy management.The methodology and analysis procedures are reproducible and all codes and data sets are available on Github. | Junyang Li Chaobo Zhang Yang Zhao Weikang Qiu Qi Chen Xuejun Zhang | 2022 | Building Simulation2022，15，6： | 1 |
| 15 | Multiblock poly(ether-b-amide)copolymers comprised of PA1212 and PPO-PEO-PPO with specific moisture-responsive and antistatic properties显示文摘Functional multiblock poly(ether-b-amide)(PEBA)copolymers,comprised of PA1212(polyamide 1212)as hard segments and Jeffamine ED-2003 as soft segments,were successfully prepared via two-step melt polycondensation without any amidation catalyst.Here,using diamino-terminated poly(propylene oxide)-poly(ethylene oxide)-poly(propylene oxide)(PPO-PEO-PPO),Jeffamine ED-2003,enhances the compatibility between polyamide oligomer and polyether,which is better than the traditional route using hydroxyl-terminated polyether.The chemical structure of multiblock PEBAs,as well as the microphase separated structure with crystalline phase of polyamide and polyether,were confirmed by heteronuclear multiple-bond correlation spectrum,heteronuclear multiple quantum correlation spectrum,Fourier transform infrared spectroscopy(FT-IR),differential scanning calorimetry and dynamic mechanical analysis.The hydrophilic PEBA copolymers showed water adsorption ranging from 87.3%to 17.1%depending on the polyether content,and specially showed moisture responsive behavior within seconds when exposed to moisture.The corresponding mechanism was studied using time-resolved attenuated total reflectance FT-IR spectroscopy in the molecular level and the water diffusion coefficient was estimated to be 1.07×10^(–8)cm^(2)∙s^(-1).Two-dimensional correlation FT-IR spectra analysis was performed to confirm that the interaction between water and polyether phase was in preference to that between water and polyamide matrix,and water molecule only forms hydrogen bond with the polyether segment.Due to the incorporation of PEO segments,the PEBAs have the surface resistivity varying from 5.6×10^(9)to 6.5×10^(10)Ω,which makes PEBA potential candidate as permanent antistatic agent. | Jie Jiang Wei Cheng Qiuyu Tang Xun Pan Jinjin Li Ling Zhao Zhenhao Xi Weikang Yuan | 2023 | Chinese Journal of Chemical Engineering2023，53，1： | 1 |
| 16 | Surface modification of electrospun fibers with mechano-growth factor for mitigating the foreign-body reaction显示文摘The implantation of synthetic polymeric scaffolds induced foreign-body reaction(FBR)seriously influence the wound healing and impair functionality recovery.A novel short peptide,mechano-growth factor(MGF),was introduced in this study to modify an electrospun polycaprolactone(PCL)fibrous scaffold to direct the macrophage phenotype transition and mitigate the FBR.In vitro studies discovered the cell signal transduction mechanism of MGF regulates the macrophage polarization via the expression of related genes and proteins.We found that macrophages response the MGF stimuli via endocytosis,then MGF promotes the histone acetylation and upregulates the STAT6 expression to direct an anti-inflammatory phenotype transition.Subsequently,an immunoregulatory electrospun PCL fibrous scaffold was modified by silk fibroin(SF)single-component layer-by-layer assembly,and the SF was decorated with MGF via click chemistry.Macrophages seeded on scaffold to identify the function of MGF modified scaffold in directing macrophage polarization in vitro.Parallelly,rat subcutaneous implantation model and rat tendon adhesion model were performed to detect the immunomodulatory ability of the MGF-modified scaffold in vivo.The results demonstrate that MGF-modified scaffold is beneficial to the transformation of macrophages to M2 phenotype in vitro.More importantly,MGF-functionalized scaffold can inhibit the FBR at the subcutaneous tissue and prevent tissue adhesion. | Yang Song Linhao Li Weikang Zhao Yuna Qian Lili Dong Yunnan Fang Li Yang Yubo Fan | 2021 | Bioactive Materials2021，6，9： | 1 |
| 17 | Modelling the Emerging COVID-19 Epidemic and Estimating Intervention Effectiveness—Taiwan,China,2021显示文摘Introduction:The coronavirus disease 2019(COVID-19)pandemic recently affected Taiwan,China.This study aimed to calculate the transmissibility of COVID-19 to predict trends and evaluate the effects of interventions.Methods:The data of reported COVID-19 cases was collected from April 20 to May 26,2021,which included daily reported data(Scenario I)and reported data after adjustment(Scenario II).A susceptibleexposed-symptomatic-asymptomatic-recovered model was developed to fit the data.The effective reproductive number(Reff)was used to estimate the transmissibility of COVID-19.Results:A total of 4,854 cases were collected for the modelling.In Scenario I,the intervention has already taken some effects from May 17 to May 26(the Reff reduced to 2.1).When the Reff was set as 0.1,the epidemic was projected to end on July 4,and a total of 1,997 cases and 855 asymptomatic individuals would have been reported.In Scenario II,the interventions were projected as having been effective from May 24 to May 26(the Reff reduced to 0.4).When the Reff was set as 0.1,the epidemic was projected to end on July 1,and a total of 1,482 cases and 635 asymptomatic individuals would have been reported.Conclusion:The epidemic of COVID-19 was projected to end after at least one month,even if the most effective interventions were applied in Taiwan,China.Although there were some positive effects of intervention in Taiwan,China. | Weikang Liu Wenjing Ye Zeyu Zhao Chan Liu Bin Deng Li Luo Jiefeng Huang Yao Wang Jia Rui Benhua Zhao Yanhua Su Shenggen Wu Kun Chen Jianming Ou Tianmu Chen | 2021 | China CDC weekly2021，3，34： | 1 |
| 18 | Manipulation of polymer foam structure based on CO_2-induced changes in polymer fundamental properties显示文摘Foaming of polymers with CO2 has attracted increasing attention in polymer processing studies.Some of the fundamental properties of polymer/CO2 systems is discussed in this short review,including solubility and diffusivity of CO2 in the polymer,polymer crystallization,interfacial tension between the polymer and the gas,and rheology of the CO2/polymers melt.These properties understandably affect the foaming process,and the structures of the foam products.Meanwhile,these properties can be changed via manipulation of CO2 in polymer.The proposed idea is to manipulate the foaming process and the foam structure by CO2-induced changes in these properties.Two cases from the authors'laboratory are presented for elucidating how to use the changes to manipulate the foaming process. | Tao Liu Dachao Li Ling Zhao Weikang Yuan | 2010 | Particuology2010，8，6： | 1 |
| 19 | Adding power of artificial intelligence to situational awareness of large interconnections dominated by inverter‐based resources显示文摘Large‐scale power systems exhibit more complex dynamics due to the increasing inte-gration of inverter‐based resources(IBRs).Therefore,there is an urgent need to enhance the situational awareness capability for better monitoring and control of power grids dominated by IBRs.As a pioneering Wide‐Area Measurement System,FNET/GridEye has developed and implemented various advanced applications based on the collected synchrophasor measurements to enhance the situational awareness capability of large‐scale power grids.This study provides an overview of the latest progress of FNET/GridEye.The sensors,communication,and data servers are upgraded to handle ultra‐high density synchrophasor and point‐on‐wave data to monitor system dynamics with more details.More importantly,several artificial intelligence(AI)‐based advanced appli-cations are introduced,including AI‐based inertia estimation,AI‐based disturbance size and location estimation,AI‐based system stability assessment,and AI‐based data authentication. | Lin Zhu Yinfeng Zhao Yi Cui Shutang You Wenpeng Yu Shengyuan Liu He Yin Chang Chen Yuru Wu Wei Qiu Mirka Mandich Hongyu Li Adedasola Ademola Chengwen Zhang Chujie Zeng Xinlan Jia Weikang Wang Haoyu Yuan Huaiguang Jiang Jin Tan Yilu Liu | 2021 | High Voltage2021，6，6： | 0 |
| 20 | Identification of TAZ as the essential molecular switch in orchestrating SCLC phenotypic transition and metastasis显示文摘Small-cell lung cancer(SCLC)is a recalcitrant cancer characterized by high metastasis.However,the exact cell type contributing to metastasis remains elusive.Using a Rb1^(L/L)/Trp53^(L/L) mouse model,we identify the NCAM^(hi)CD44^(lo/–) subpopulation as the SCLC metastasizing cell(SMC),which is progressively transitioned from the non-metastasizing NCAM^(lo)CD44^(hi) cell(non-SMC).Integrative chromatin accessibility and gene expression profiling studies reveal the important role of the SWI/SNF complex,and knockout of its central component,Brg1,significantly inhibits such phenotypic transition and metastasis.Mechanistically,TAZ is silenced by the SWI/SNF complex during SCLC malignant progression,and its knockdown promotes SMC transition and metastasis.Importantly,ectopic TAZ expression reversely drives SMC-to-non-SMC transition and alleviates metastasis.Single-cell RNA-sequencing analyses identify SMC as the dominant subpopulation in human SCLC metastasis,and immunostaining data show a positive correlation between TAZ and patient prognosis.These data uncover high SCLC plasticity and identify TAZ as the key molecular switch in orchestrating SCLC phenotypic transition and metastasis. | Yujuan Jin Qiqi Zhao Weikang Zhu Yan Feng Tian Xiao Peng Zhang Liyan Jiang Yingyong Hou Chenchen Guo Hsinyi Huang Yabin Chen Xinyuan Tong Jiayu Cao Fei Li Xueliang Zhu Jun Qin Dong Gao Xin-Yuan Liu Hua Zhang Luonan Chen Roman KThomas Kwok-Kin Wong Lei Zhang Yong Wang Liang Hu Hongbin Ji | 2022 | National Science Review2022，9，7： | 0 |
