| 1 | Effect of particle shape and size on flow properties of lactose powders显示文摘The shape and size of particles are understood to affect the bulk behaviour of powders, though there are but few studies that present quantitative information on the relationship between particle shape and the flow properties of powder. This is due in part to the lack of techniques for rapidly determining both particle shape and the range of flow characteristics that describe the response of powders to the stress and shear experienced during their processing. This study presents data that quantifies the influence of particle shape/size of three different lactose powders on their respective flow and bulk characteristics. Two of the samples differ in size but have similar shapes; the third sample is more spherical but similar in size to one of the other two samples. The results demonstrate that in addition to particle size, particle shape significantly affect the flow characteristics of a powder over a wide range of stress conditions. | Xiaowei Fu Deborah Huck Lisa Makein Brian Armstrong Ulf Willen Tim Freeman | 2012 | Particuology2012，10，2： | 22 |
| 2 | Metal-Organic Framework Nanocarriers for Drug Delivery in Biomedical Applications显示文摘Investigation of metal–organic frameworks(MOFs)for biomedical applications has attracted much attention in recent years.MOFs are regarded as a promising class of nanocarriers for drug delivery owing to well-defined structure,ultrahigh surface area and porosity,tunable pore size,and easy chemical functionalization.In this review,the unique properties of MOFs and their advantages as nanocarriers for drug delivery in biomedical applications were discussed in the first section.Then,state-ofthe-art strategies to functionalize MOFs with therapeutic agents were summarized,including surface adsorption,pore encapsulation,covalent binding,and functional molecules as building blocks.In the third section,the most recent biological applications of MOFs for intracellular delivery of drugs,proteins,and nucleic acids,especially aptamers,were presented.Finally,challenges and prospects were comprehensively discussed to provide context for future development of MOFs as efficient drug delivery systems. | Yujia Sun Liwei Zheng Yu Yang Xu Qian Ting Fu Xiaowei Li Zunyi Yang He Yan Cheng Cui Weihong Tan | 2020 | Nano-Micro Letters2020，12，8： | 10 |
| 3 | Comparison of sentinel lymph node detection performances using blue dye in conjunction with indocyanine green or radioisotope in breast cancer patients: a prospective singlecenter randomized study显示文摘Objective:This randomized study aimed to compare the clinical efficacy between the novel dual tracer composed of indocyanine green(ICG)and blue dye(BD)and the conventional dual tracer composed of radioisotope and BD for sentinel lymph node(SLN)mapping in patients with breast cancer.Methods:This study enrolled 471 clinically lymph node-negative patients with primary breast cancer.All patients underwent mastectomy,and those undergoing sentinel lymph node biopsy(SLNB)were randomized to receive blue dye plus radioisotope(RB group)or BD plus ICG(IB group).The detection performances on SLN identification rate,positive SLN counts,detection sensitivity,and false-negative rate were compared between the two groups.Results:In the IB group,97%(194/200)of the patients who underwent the ICG and BD dual tracer injection showed fluorescentpositive lymphatic vessels within 2–5 min.The identification rate of SLNs was comparable between the IB group(99.0%,198/200)and the RB group(99.6%,270/271)(P=0.79).No significant differences were observed in the identification rate of metastatic SLNs(22.5%vs.22.9%,P>0.05,RB group vs.IB group,the same below),positive SLN counts(3.72±2.28 vs.3.91±2.13,P>0.05),positive metastatic SLN counts(0.38±0.84 vs.0.34±0.78,P>0.05),SLNB detection sensitivity(94.4%vs.92.5%,P>0.05),or false-negative rate(5.6%vs.7.5%,P>0.05)between the two groups.Conclusions:ICG can be used as a promising alternative tracer for radioisotope in SLN mapping,and when it is combined with BD in lymphangiography,it offers comparable detection sensitivity compared to the conventional lymphatic mapping strategies that are widely used in clinical practice. | Long Yuan Xiaowei Qi Yi Zhang Xinhua Yang Fan Zhang Linjun Fan Li Chen Kongyong Zhang Ling Zhong Yanling Li Sijie Gan Wenying Fu Jun Jiang | 2018 | Cancer Biology & Medicine2018，15，4： | 9 |
| 4 | Sporopollen analysis of Core B10 in the southern Yellow Sea and the reflected characteristics of climate changes显示文摘Eight sporopollen zones have been divided based on the results of high-resolution sporopollen analysis of Core B10 in the southern Yellow Sea. Based on the results along with ^14C datings and the subbottom profiling data,climatic and environmental changes since the last stage of late Pleistocene are discussed. The main conclusions are drawn as follows: (1) the vegetation evolved in the process of coniferous forest-grassland containing broad-leaved trees→coniferous and broad-leaved mixed forest→coniferons and broad-leaved mixed forest-grassland prevailed by coniferous trees→coniferous and broad-leaved mixed forest-grassland containing evergreen broad-leaved trees→coniferons and broad-leaved mixed forest-grassland prevailed by broadleaved trees→deciduous broad-leaved forest-meadow containing evergreen broad-leaved trees→coniferous and broadleaved mixed forest-grassland prevailed by broad-leaved trees→coniferous and broad-leaved mixed forest containing evergreen broad-leaved trees; (2) eight stages of climate changes are identified as the cold and dry stage, the temperate and wet stage, the cold and dry stage, the warm and dry stage, the temperate and wet stage, the hot and dry stage, the temperate and dry stage, then the warm and dry stage in turn; (3) the sedimentary environment developed from land,to littoral zone, to land again, then to shore-neritic zone; and (4) the Yellow Sea Warm Current formed during early-Holocene rather than Atlantic stage. | FU Mingzuo~(1,2,3), LI Zhen~1, XU Xiaowei~1 & SHl Xuefa~1 1.

| 5 | Pathological changes in the lungs and lymphatic organs of 12 COVID-19 autopsy cases显示文摘Systematic autopsy and comprehensive pathological analyses of COVID-19 decedents should provide insights into the disease characteristics and facilitate the development of novel therapeutics.In this study,we report the autopsy findings from the lungs and lymphatic organs of 12 COVID-19 decedents—findings that evaluated histopathological changes;immune cell signature and inflammatory factor expression in the lungs,spleen and lymph nodes.Here we show that the major pulmonary alterations included diffuse alveolar damage,interstitial fibrosis and exudative inflammation featured with extensive serous and fibrin exudates,macrophage infiltration and abundant production of inflammatory factors(IL-6,IP-10,TNFo?and IL-I f).The spleen and hilar lymph nodes contained lesions with tissue structure disruption and immune cell dysregulation,including lymphopenia and macrophage accumulation.These findings provide pathological evidence that links injuries of the lungs and lymphatic organs with the fatal systematic respiratory and immune malfunction in critically ill COVID-19 patients. | Qian Liu Yu Shi Jun Cai Yaqi Duan Rongshuai Wang Hongyan Zhang Qiurong Ruan Jiansha Li Lei Zhao Yifang Ping Rong Chen Liang Ren Xiaochun Fei Heng Zhang Rui Tang Xi Wang Tao Luo Xindong Liu Xuequan Huang Zhenhua Liu Qilin Ao Yong Ren Jing Xiong Zhicheng He Haibo Wu Wenjuan Fu Pengnan Zhao Xinwei Chen Guoqiang Qu Yunyun Wang Xi Wang Jia Liu Dongfang Xiang Sanpeng Xu Xiaowei Zhou Qingrui Li Jinghong Ma Heng Li Jie Zhang Sizhe Huang Xiaohong Yao Yiwu Zhou Chaofu Wang Dingyu Zhang Guoping Wang Liang Liu Xiu-Wu Bian | 2020 | National Science Review2020，7，12： | 6 |
| 6 | Post-Orogenic Tectonic Evolution of the Jiangnan-Xuefeng Orogenic Belt:Insights from Multiple Geochronometric Dating of the Mufushan Massif,South China显示文摘The Mufushan massif, as continental intra-plate magmatites located in the Jiangnan-Xuefeng orogenic belt of the South China. The Mufushan massif constitutes the largest Mesozoic intrusive complex, intruded the Mesoproterozoic Lengjiaxi Formation. Multiple geochronometric dating was used to reconstruct their evolution from emplacement to exhumation. The Mufushan granitoids were emplaced at ~150 Ma(U-Pb zircon) as post-orogenic magmatites contributing to Triassic crustal thickening. Onset of regional extension at ~128 Ma(40Ar/39Ar white mica and biotite) manifests a tectonic regime switch. Intense exhumation prior to ~55 Ma was followed by slow denudation and peneplanation for the next 37 Ma(~55–18 Ma). Accelerated cooling since ~18 Ma may have been caused by a far-field effect of the collision between IndiaAsia Plate or the Pacific-Plate subduction. Through a multi-geochronometric approach, this study provides a new comprehensive model for the cause of the intra-plate magmatism formation in the South China, and also established a reliable geochronological framework of the post-orogenic tectonic evolutions of the Jiangnan-Xuefeng orogenic belt. | Chuanbo Shen Di Hu Kyoungwon Min Chaoqun Yang Xiaowei Zeng Hongyang Fu Xiang Ge | 2020 | Journal of Earth Science2020，31，5： | 4 |
| 7 | Mobility control of unmanned aerial vehicle as communication relay in airborne multi-user systems显示文摘In this paper, a model-based adaptive mobility control method for an Unmanned Aerial Vehicle(UAV) acting as a communication relay is presented, which is intended to improve the network performance in airborne multi-user systems. The mobility control problem is addressed by jointly considering unknown Radio Frequency(RF) channel parameters, unknown multi-user mobility, and non-available Angle of Arrival(AoA) information of the received signal. A Kalman filter and a least-square-based estimation algorithm are used to predict the future user positions and estimate the RF channel parameters between the users and the UAV, respectively. Two different relay application cases are considered: end-to-end and multi-user communications. A line search algorithm is proposed for the former, with its stability given and proven, whereas a simplified gradient-based algorithm is proposed for the latter to provide a target relay position at each decision time step, decreasing the two-dimensional search to a one-dimensional search. Simulation results show that the proposed mobility control algorithms can drive the UAV to reach or track the optimal relay position movement, as well as improving network performance. The proposed method reflects the properties of using different metrics as objective network performance functions. | Gaofeng WU Xiaoguang GAO Xiaowei Fu Kaifang WAN Ruohai DI | 2019 | Chinese Journal of Aeronautics2019，32，6： | 4 |

| 9 | Antagonism of toll-like receptor 2 attenuates the formation and progression of abdominal aortic aneurysm显示文摘Abdominal aortic aneurysm(AAA) is an inflammatory vascular disorder with high mortality.Accumulating evidence shows that toll-like receptor 2(TLR2) plays a critical role in the regulation of wound-repairing process after tissue injury.We wondered if TLR2 signaling contributed to the pathogenesis of AAA and that targeting TLR2 would attenuate AAA development and progression.In this study,enhanced expression of TLR2 and its ligands were observed in human AAA tissue.Neutralization of TLR2 protected against AAA development and caused established AAA to regress in mouse models of AAA.In addition,TLR2-deficient mice also failed to develop AAA.The prophylactic and therapeutic effects of blocking TLR2 were accompanied by a significant resolution of inflammation and vascular remodeling,as indicated by the decreased expression or activity of MMP-2/9,α-SMA,inflammatory cytokines,and transcription factors NF-κB,AP-1 and STAT1/3 in AAA tissue.Mechanistically,blocking TLR2 decreased the expression and interaction of TLR2 and several endogenousligands,which diminished chronic inflammation and vascular remodeling in the vascular tissue of AAA.Our studies indicate that the interactions between TLR2 and its endogenous ligands contribute to the pathogenesis of AAA and that targeting TLR2 offers great potential toward the development of therapeutic agents against AAA. | Huimin Yan Bing Cui Xiaowei Zhang Xiaoming Fu Jun Yan Xiaoxing Wang Xiaoxi Lv Zhong Chen Zhuowei Hu | 2015 | Acta Pharmaceutica Sinica B2015，5，3： | 3 |
| 10 | Placement of unmanned aerial vehicles as communication relays in two-tiered multi-agent system:clustering based methods显示文摘The network performance and the unmanned aerial vehicle(UAV)number are important objectives when UAVs are placed as communication relays to enhance the multi-agent information exchange.The problem is a non-deterministic polynomial hard(NP-hard)multi-objective optimization problem,instead of generating a Pareto solution,this work focuses on considering both objectives at the same level so as to achieve a balanced solution between them.Based on the property that agents connected to the same UAV are a cluster,two clustering-based algorithms,M-K-means(MKM)and modified fast search and find density of peaks(MFSFDP)methods,are first proposed.Since the former algorithm requires too much computational time and the latter one requires too many relays,an algorithm for the balanced network performance and relay number(BPN)is proposed by discretizing the area to avoid missing the optimal relay positions and defining a new local density function to reflect the network performance metric.Simulation results demonstrate that the proposed algorithms are feasible and effective.Comparisons between these algorithms show that the BPN algorithm uses fewer relay UAVs than the MFSFDP and classic set-covering based algorithm,and its computational time is far less than the MKM algorithm. | WU Gaofeng WAN Kaifang GAO Xiaoguang FU Xiaowei | 2020 | Journal of Systems Engineering and Electronics2020，31，2： | 3 |
| 11 | Calcium silicate accelerates cutaneous wound healing with enhanced re-epithelialization through EGF/EGFR/ERK-mediated promotion of epidermal stem cell functions显示文摘Background:Human epidermal stem cells(hESCs)play an important role in re-epithelialization and thereby in facilitating wound healing,while an effective way to activate hESCs remains to be explored.Calcium silicate(CS)is a form of bioceramic that can alter cell behavior and promote tissue regeneration.Here,we have observed the effect of CS on hESCs and investigated its possible mechanism.Methods:Using a mouse full-thickness skin excision model,we explored the therapeutic effect of CS on wound healing and re-epithelialization.In vitro,hESCs were cultured with diluted CS ion extracts(CSIEs),and the proliferation,migration ability and stemness of hESCs were evaluated.The effects of CS on the epidermal growth factor(EGF),epidermal growth factor receptor(EGFR)and extracellular signal-related kinase(ERK)signaling pathway were also explored.Results:In vivo,CS accelerated wound healing and re-epithelialization.Immunohistochemistry demonstrated that CS upregulated cytokeratin 19 and integrinβ1 expression,indicating that CS improved hESCs stemness.In vitro studies confirmed that CS improved the biological function of hESCs.And the possible mechanism could be due to the activation of the EGF/EGFR/ERK signaling pathway.Conclusion:CS can promote re-epithelialization and improve the biological functions of hESCs via activating the EGF/EGFR/ERK signaling pathway. | Bingmin Li Haowen Tang Xiaowei Bian Kui Ma Jiang Chang Xiaobing Fu Cuiping Zhang | 2021 | Burns & Trauma2021，9，1： | 3 |
| 12 | Enhancing the power conversion efficiency of PCDTBT:PC_(71)BM polymer solar cells using a mixture of solvents显示文摘Organic polymer solar materials are shown to exhibit better solubility in mixed solvents than in pure ones,which affects the performance of their solar cells.In this article,poly[N-9-hepta-decanyl-2,7-carbazole-alt-5,5-(4.7-di-2-thienyI-2,l,3-benzothiadiazole)(PCDTBT0)and[6,6]-phenyl-C71-butyric acid methyl ester(PC_(71)BM)are used as active layer materials in solar cells.To optimize the performance of these active materials,the ratio of chloroform(CF)to chlorobenzene used as solvents to dissolve PCDTBT,and PC_(71)BM is varied,which is shown to affect power conversion efficiency(PCE).The solar cell that shows the best performance with a PCE as high as 6.82%is produced using a volume ratio of CF to chlorobenzene of1:1. | Shaopeng Yang Ye Zhang Tao Jiang Xuefeng Sun Chaoqun Lu Guang Li Xiaowei Li Guangsheng Fu | 2014 | Chinese Science Bulletin2014，59，3： | 2 |

| 14 | Neural circuit control of innate behaviors显示文摘All animals possess a plethora of innate behaviors that do not require extensive learning and are fundamental for their survival and propagation.With the advent of newly-developed techniques such as viral tracing and optogenetic and chemogenetic tools,recent studies are gradually unraveling neural circuits underlying different innate behaviors.Here,we summarize current development in our understanding of the neural circuits controlling predation,feeding,male-typical mating,and urination,highlighting the role of genetically defined neurons and their connections in sensory triggering,sensory to motor/motivation transformation,motor/motivation encoding during these different behaviors.Along the way,we discuss possible mechanisms underlying binge-eating disorder and the pro-social effects of the neuropeptide oxytocin,elucidating the clinical relevance of studying neural circuits underlying essential innate functions.Finally,we discuss some exciting brain structures recurrently appearing in the regulation of different behaviors,which suggests both divergence and convergence in the neural encoding of specific innate behaviors.Going forward,we emphasize the importance of multi-angle and cross-species dissections in delineating neural circuits that control innate behaviors. | Wei Xiao Zhuo-Lei Jiao Esra Senol Jiwei Yao Miao Zhao Zheng-Dong Zhao Xiaowei Chen Peng Cao Yu Fu Zhihua Gao Wei L Shen Xiao-Hong Xu | 2022 | Science China(Life Sciences)2022，65，3： | 2 |
| 15 | Coalition Formation for Multiple UAVs Cooperative Search and Attack with Communication Constraints in Unknown Environment显示文摘A coalition formation algorithm is presented with limited communication ranges and delays in unknown environment,for the performance of multiple heterogeneous unmanned aerial vehicles(UAVs)in cooperative search and attack missions.The mathematic model of coalition formation is built on basis of the minimum attacking time and the minimum coalition size with satisfying resources and simultaneous strikes requirements.A communication protocol based on maximum number of hops is developed to determine the potential coalition members in dynamic network.A multistage sub-optimal coalition formation algorithm(MSOCFA)with polynomial time is established.The performances of MSOCFA and particle swarm optimization(PSO)algorithms are compared in terms of complexity,mission performance and computational time.A complex scenario is deployed to illustrate how the coalitions are formed and validate the feasibility of the MSOCFA.The effect of communication constraints(hop delay and max-hops)on mission performance is studied.The results show that it is beneficial to determine potential coalition members in a wide and deep range over the network in the presence of less delay.However,when the delays are significant,it is more advantageous to determine coalitions from among the immediate neighbors. | Liu Zhong Gao Xiaoguang Fu Xiaowei | 2017 | Transactions of Nanjing University of Aeronautics and Astronautics2017，34，6： | 2 |
