1Human activities and elevational constraints restrict ranging patterns of snub-nosed monkeys in a mountainous refuge显示文摘Both natural conditions and anthropogenic factors affect the survivability,distribution,and population density of wildlife.To understand the extent and how these factors drive species distributions,a detailed description of animal movement patterns in natural habitats is needed.In this study,we used satellite telemetry to monitor elevational ranges favored by endangered golden snub-nosed monkeys(Rhinopithecus roxellana),in the Qinling Mountains,central China.We investigated the abundance and distribution of food resources through sampling vegetation quadrats at different elevations and sampled anthropogenic activities using field surveys.Our results indicated that although there was no significant variation in food resources between low-(<1500 m)and middle-elevations(1500–2200 m),monkeys were found most often in areas above 1500 m,where there was less anthropogenic development(e.g.houses and roads);however,monkeys rarely ranged above 2200 m and had limited food availability at this altitude.There was limited human disturbance at this elevation.We suggest that both human activity and ecological constraints(i.e.food resources)have considerable effects on elevational use of R.roxellana in the Qinling Mountains.This study highlights the critical roles these factors can play in shaping the vertical distribution of high-altitude primates.This research provides useful insights for habitat-based conservation plans in which human disturbance management and habitat restoration should be prioritized.Pengzhen HUANG Kun BIAN Zhipang HUANG Qi Li Derek WDUNN Gu FANG Jiahui LIU Mengyao WANG Xianfeng YANG Ruliang PAN Cunlao GAO Kaichuang SI Baoguo LI Xiaoguang QI 2021Integrative Zoology2021,16,2:3

3A mechanically durable,excellent recyclable 3D hierarchical Ni_(3)S_(2)@Ni foam photothermal membrane显示文摘Solar-driven water evaporation is considered to be a viable and very efficient technology for fresh water production.Unfortunately,the photothermal membrane has a low absorptivity,low photothermal conversion and poor recyclability,which are difficult to meet the demands of self-floating solar driven evaporators in practical applications.Herein,a hierarchical nanostructure Ni_(3)S_(2) has been prepared by in-situ growing method on Ni foam(NF),which shows excellent absorptivity,outstanding recyclable and high mechanically durable properties.The photothermal membrane was composed of hierarchical nanostructure Ni_(3)S_(2)@NF,which exhibited excellent solar absorption(93.13%) in the wavelength range of 250–2500 nm and sustained anti-corrosion capacity for one month.In addition,the hierarchical nanostructure Ni_(3)S_(2)@NF has good hydrophilicity and strong binding force,indicating this photothermal membrane exhibits good stability and outstanding photothermal conversion efficiency.An evaporation system based on 3D Ni_(3)S_(2)@NF membrane exhibited excellent water evaporation ability,the highest water evaporation rate(1.53 kg m^(-2)h^(-1)) and the photothermal conversion efficiency(84.7%) under 1 sun illumination.In the desalination experiment,the water evaporation rate and photothermal conversion efficiency almost keep constant over 5 cycles tests and do not decrease compared with the experiment in pure water.This result demonstrated that the Ni_(3)S_(2)@NF membrane has shown good corrosion resistance and outstanding recyclability.Due to the simple preparation method,low cost,outstanding recyclability and high mechanical durability in the sea water,this Ni_(3)S_(2)@NF membrane have great potential for long-term solar distillation applications.Zhongping Yao Kailun Yu Mengyao Pan Hongbo Xu Tianqi Zhao Zhaohua Jiang 2022Green Energy & Environment2022,7,3:1
4Mode hopping and polarization switching of mutually coupled vertical-cavity surface-emitting lasers显示文摘We perform a theoretical study on the polarization-resolved compound lasing mode (CLM) of two mutually coupled vertical-cavity surface-emitting lasers (VCSELs). Different solutions of CLMs are derived though stability analysis of the spin-flip model. The dynamical evolvements of CLMs with the existence of polarization degrees of freedom are also charactered. The most stable CLM with the smallest carrier density tend to be excited, since the gain needed for this mode to emit is the lowest. In the given system, varying values of injection rate or birefringence, etc., will change the generation of the preferred CLMs in the two polarization directions, and thus influence the polarization switching (PS) characteristics. Thus, hoppings between CLMs are also companied by PSs. Through mapping of average power in the parameter space, the influences of coupling rate and anisotropy parameters (linear dichroism and linear birefringence) on PS and hopping between CLMs are discussed.ZHANG WeiLi PAN Wei LUO Bin WANG MengYao ZOU XiHua 2008Science in China(Series F)2008,51,5:0

6The interactive process of cultural landscape:Taking the trails around Zhengqi Pavilion as an example显示文摘Cultural landscape is a social natural process under which people actively participate in thinking,feeling,and acting.On this basis,their connection with a certain part of the environment in turn affects people’s perception of the world and the products of their actions.Trails is a representative and complex practice of integrating nature into society and transforming it into a mixed entity.However,the dynamic and diverse relationships of cultural landscapes represented by this interactive process have not been well interpreted in landscape research.The research first discusses the conceptualization and value theory of cultural landscape,and develops the methodology of cultural landscape interaction process research combining typology and Network theory.Taking the trails spontaneously formed around the Zhengqi Pavilion of Sun Yat-sen Mausoleum in Nanjing as an example,this paper discusses the interaction process of trails as a cultural landscape.Based on the analysis results,we obtained the dynamic characteristics of cultural landscapes by treating trails as a network,while obtaining the value expression created by typology.Mengyao Pan Huayu Guo Qi Zhou Jiangtao Xie 2023Frontiers of Architectural Research2023,12,6:0
7Detecting gravitational wave with an interferometric seismometer array on lunar nearside显示文摘Our Moon is by far the easiest natural, extraterrestrial celestial object for us to reach, and many space agencies, in particular the China National Space Administration, have publicized plans for manned missions there. Such high-profile projects must yield commensurate scientific outputs to justify their cost to the taxpayers. An important criterion for the selection of candidate experiments is the extent to which the Moon plays an integral and irreplaceable role, as opposed to offering only marginal advantages over Earth-orbit, space-based alternatives. In this study, we propose an experiment that excels in this regard, which considers the Moon as part of the experimental apparatus. Specifically, the Moon acts as a Weber bar-style resonant mass that responds to deci-Hertz gravitational waves(GWs). GW-excited lunar vibrations can be picked up by an array of(prefabricated on Earth and easy to transport to the Moon) small laser interferometric seismometers yielding GW detection. Such a setup would plug a gap in the GW frequency range already covered by the existing or underdevelopment detectors, and it can inform us on important astrophysics topics, such as the progenitors of Type Ia supernovae(SNe Ia) or intermediate mass black holes. We provide the instrument design as well as its deployment strategy, and we also summarize relevant science cases according to the estimated viable sensitivity.Junlang Li Fangfei Liu Yuan Pan Zijian Wang Mengdi Cao Mengyao Wang Fan Zhang Jinhai Zhang Zong-Hong Zhu 2023Science China(Physics,Mechanics & Astronomy)2023,66,10:0

10Superhydrophobic Surface-Assisted Preparation of Microspheres and Supraparticles and Their Applications显示文摘Superhydrophobic surface(SHS) has been well developed, as SHS renders the property of minimizing the water/solid contact interface. Water droplets deposited onto SHS with contact angles exceeding 150°, allow them to retain spherical shapes, and the low adhesion of SHS facilitates easy droplet collection when tilting the substrate. These characteristics make SHS suitable for a wide range of applications. One particularly promising application is the fabrication of microsphere and supraparticle materials. SHS offers a distinct advantage as a universal platform capable of providing customized services for a variety of microspheres and supraparticles. In this review, an overview of the strategies for fabricating microspheres and supraparticles with the aid of SHS, including cross-linking process, polymer melting,and droplet template evaporation methods, is first presented. Then, the applications of microspheres and supraparticles formed onto SHS are discussed in detail, for example, fabricating photonic devices with controllable structures and tunable structural colors, acting as catalysts with emerging or synergetic properties, being integrated into the biomedical field to construct the devices with different medicinal purposes, being utilized for inducing protein crystallization and detecting trace amounts of analytes. Finally,the perspective on future developments involved with this research field is given, along with some obstacles and opportunities.Mengyao Pan Huijuan Shao Yue Fan Jinlong Yang Jiaxin Liu Zhongqian Deng Zhenda Liu Zhidi Chen Jun Zhang Kangfeng Yi Yucai Su Dehui Wang Xu Deng Fei Deng 2024Nano-Micro Letters2024,16,4:0
11AIFM1 variants associated with auditory neuropathy spectrum disorder cause apoptosis due to impaired apoptosis-inducing factor dimerization显示文摘Auditory neuropathy spectrum disorder(ANSD)represents a variety of sensorineural deafness conditions characterized by abnormal inner hair cells and/or auditory nerve function,but with the preservation of outer hair cell function.ANSD represents up to 15%of individuals with hearing impairments.Through mutation screening,bioinformatic analysis and expression studies,we have previously identified several apoptosis-inducing factor(AIF)mitochondria-associated 1(AIFM1)variants in ANSD families and in some other sporadic cases.Here,to elucidate the pathogenic mechanisms underlying each AIFM1 variant,we generated AIF-null cells using the clustered regularly interspersed short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9)system and constructed AIF-wild type(WT)and AIF-mutant(mut)(p.T260A,p.R422W,and p.R451Q)stable transfection cell lines.We then analyzed AIF structure,coenzyme-binding affinity,apoptosis,and other aspects.Results revealed that these variants resulted in impaired dimerization,compromising AIF function.The reduction reaction of AIF variants had proceeded slower than that of AIF-WT.The average levels of AIF dimerization in AIF variant cells were only 34.5%-49.7%of that of AIF-WT cells,resulting in caspase-independent apoptosis.The average percentage of apoptotic cells in the variants was 12.3%-17.9%,which was significantly higher than that(6.9%-7.4%)in controls.However,nicotinamide adenine dinucleotide(NADH)treatment promoted the reduction of apoptosis by rescuing AIF dimerization in AIF variant cells.Our findings show that the impairment of AIF dimerization by AIFM1 variants causes apoptosis contributing to ANSD,and introduce NADH as a potential drug for ANSD treatment.Our results help elucidate the mechanisms of ANSD and may lead to the provision of novel therapies.YUE QIU HONGYANG WANG HUAYE PAN JING GUAN LEI YAN MINGJIE FAN HUI ZHOU XUANHAO ZHOU KAIWEN WU ZEXIAO JIA QIANQIAN ZHUANG ZHAOYING LEI MENGYAO LI XUE DING AIFU LIN YONG FU DONG ZHANG QIUJU WANG QINGFENG YAN 2023Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023,24,2:0
