1Microscopic structures of ionic liquids 1-ethyl-3-methylimidazolium tetrafluoroborate in water probed by the relative chemical shift显示文摘The relative chemical shifts (△δ) △δwere put forward to investigate the microscopic structure of 1-ethyl-3-methyl-imidazolium tetrafluoroborate (EmimBF4) during the dilution process with water.The concentration-dependent △δ(C2)H-(C4)H,△δ(C2)H-(C5)H and △δ(C4)H-(C5)H were analyzed.The results reveal that the variations of the microscopic structures of three aromatic protons are inconsistent.The strength of the H-bond between water and three aromatic protons follows the order:(C2)H···O > (C4)H···O > (C5)H···O.The concentration-dependent △δ(C6)H-(C7)H and △δ(C6)H-(C8)H indicate the formation of the H-bonds of (Calkyl)H···O is impossible,and more water is located around (C6)H than around (C7)H or (C8)H.The concentration-dependent △δ(C2)H-(C4)H and △δ(C2)H-(C5)H both increase rapidly when xwater > 0.9 or so,suggesting the ionic pairs of EmimBF4 are dissociated rapidly.The turning points of concentration-dependent △δ(C2)H-(C4)H and △δ(C2)H-(C5)H indicate that some physical properties of the EmimBF4/water mixtures also change at the corresponding concentration point.The microscopic structures of EmimBF4 in water could be clearly detected by the relative chemical shifts.XU YingJie GAO Yan ZHANG LiQun YAO Jia WANG CongMin LI HaoRan 2010Science China Chemistry2010,53,7:8
2Geochronology, Geochemistry, and Hf Isotopic Compositions of Monzogranites and Mafic-Ultramafic Complexes in the Maxingdawannan Area, Eastern Kunlun Orogen, Western China: Implications for Magma Sources, Geodynamic Setting, and Petrogenesis显示文摘This paper presents zircon U-Pb-Hf isotopic compositions and whole-rock geochemical data for monzogranites and mafic-ultramafic complexes of the Maxingdawannan area in the western end of the east Kunlun orogenic belt, western China. The data are used to determine the ages, petrogenesis, magma sources, and geodynamic setting of the studied rocks. U-Pb zircon dating indicates that monzogranites and gabbros of the complexes were emplaced at 399 and 397 Ma, respectively. The monzogranites are shoshonitic, with high SiO2, Al2 O3 and total-alkali contents, and low TFeO, MgO, TiO2 and P2 O5 contents. The mafic-ultramafic complexes are characterized by low Si O2 contents. The monzogranites display enrichment in light rare-earth elements(LREE) and large-ion lithophile elements(LILE), depletion in heavy REEs(HREE) and high-field-strength elements(HFSE), and negative Eu anomalies(Eu/Eu*=0.36–0.48). The mafic-ultramafic complexes are also enriched in LREEs and LILEs, and depleted in HREEs and HFSEs, with weak Eu anomalies(Eu/Eu*=0.84–1.16). Zircon εHf(t) values for the monzogranites and mafic-ultramafic complexes range from-6.68 to 1.11 and-1.81 to 6.29, with zircon model ages of 1 812–1 319 Ma(TDM2) and 1 087–769 Ma(TDM1), respectively. Hf isotopic data indicate that primary magmas of the monzogranites are originated from partial melting of ancient lower crust during the Paleo-Mesoproterozoic, with a juvenile-crust component. Primitive magmas of the mafic-ultramafic complexes are likely originated from a depleted-mantle source modified by slab-derived fluids and contaminated by crustal components. Geochemical data and the geological setting indicate that Devonian intrusions in the Maxingdawannan area are related to northward subduction of the ProtoTethys oceanic lithosphere.Jiaming Yan Guosheng Sun Fengyue Sun Liang Li Haoran Li Zhenhua Gao Lei Hua Zhengping Yan 2019Journal of Earth Science2019,30,2:6

4Bimodular effects of D614G mutation on the spike glycoprotein of SARS-CoV-2 enhance protein processing,membrane fusion,and viral infectivity显示文摘Dear Editor,By the end of June 2020,the pandemic of coronavirus diseases 2019(COVID-19)had resulted in more than 10 million individuals,all over the world,being infected with the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).1 The high contagiousness of SARS-CoV-2 virus was largely attributed to the relatively unique sequence composition in its spike(S)glycoprotein,which is in charge of the host entry by interacting with its cellular receptor angiotensin-converting enzyme 2(ACE2).2,3 The S glycoprotein can be processed into an N terminal S1 fragment that is responsible for receptor binding,and a C terminal S2 fragment that functions to promote membrane fusion.4 SARS-CoV-2 is a type of single-stranded positive-sense ribonucleic acid(RNA)virus,and an increasing number of mutations were identified across the SARS-CoV-2 genome,including the region encoding S glycoprotein.Nevertheless,the functional implications of these mutations remain largely unknown,we here reported the mutation analysis of S gene and a functional exploration of the dominant D614G mutation.Xiaoyi Jiang Zhengrong Zhang Chenxi Wang Hongguang Ren Lihua Gao Haoran Peng Zubiao Niu He Ren Hongyan Huang Qiang Sun 2020Signal Transduction and Targeted Therapy2020,5,1:5

6Joint Computation Offloading and Resource Allocation for Mobile-Edge Computing Assisted Ultra-Dense Networks显示文摘Mobile-edge computing(MEC),enabling to offload computing tasks on mobile devices towards edge servers,can reduce the terminals cost.However,a single MEC sever usually has limited computing capabilities,which can not meet a large number of terminals’requirements.In this paper,we consider an ultra-dense networks(UDN)scenario where the macro base stations(MBSs)are assisted by MEC severs.In particular,we first construct system model for MEC assisted UDN,and build the system overhead minimization.Next,in order to solve the problem,we transform the problem into three sub-problems,i.e.,offloading strategies subproblem,channel assignments subproblem,and power allocation subproblem.Then,employing joint offloading and resource allocation algorithms,we obtain the optimal joint strategy for the MEC assisted UDNs.Finally,simulations are conducted to evaluate the performance of our proposed algorithms.Numerical results show that obtained algorithms can effectively reduce the energy consumption of the system and improve the overall performance of the system.Ya Gao Haoran Zhang Fei Yu Yujie Xia Yongpeng Shi 2022Journal of Communications and Information Networks2022,7,1:3
7Correlation between antioxidant depletion kinetic model and ageing behaviour of cross-linked polyethylene cable insulation显示文摘A concise kinetic model catering for the antioxidant reaction of thermally aged crosslinked polyethylene(XLPE)cable insulation before its abrupt performance deterioration is proposed for life prediction and condition assessment.The alternating current breakdown strength,elongation at break,carbonyl index,and pyrolysis activation energy of XLPE insulation are found to consistently display an abrupt change at a certain point of ageing time.This is strongly correlated to the depletion of the antioxidant whose content gradually decreases with ageing time and drops to a critical value,after which the abrupt degradation of the above macroscopic performances happens.Based on the simplified chain reactions of XLPE during thermal-oxidative ageing,a concise kinetic model about antioxidant prediction is accordingly established by solving the chemical kinetics equations.It indicates that the antioxidant content decays with the reciprocal of time before the abrupt degradation occurs.Results of antioxidant content predicted by the kinetic model at different temperatures matches well with the experimental results,and its reliability can also be proved by the Arrhenius relationship of the obtained results.The kinetic model proposed herein demonstrates satisfying conciseness and thus can be highly feasible in ageing condition assessment and life predicting of XLPE insulation.Yingying Zheng Yiwei Long Delun Yi Haoran Zhang Jian Gao Kangning Wu Jianying Li 2023High Voltage2023,8,2:2
8PM_(2.5) exposure associated with microbiota gut-brain axis:Multi-omics mechanistic implications from the BAPE study显示文摘Recent studies have shown that PM_(2.5) may activate the hypothalamus-pituitary-adrenal(HPA)axis by inducing hormonal changes,potentially explaining the increase in neurological and cardiovascular risks.In addition,an association between PM_(2.5) and gut microbiota and metabolites was established.The above evidence represents crucial parts of the gut-brain axis(GBA).In view of this evidence.Tiantian Li Jianlong Fang Song Tang Hang Du Liang Zhao Yanwen Wang Fuchang Deng Yuanyuan Liu Yanjun Du Liangliang Cui Wanying Shi Yan Wang Jiaonan Wang Yingjian Zhang Xiaoyan Dong Ying Gao Yu Shen Li Dong Huichan Zhou Qinghua Sun Haoran Dong Xiumiao Peng Yi Zhang Meng Cao Hong Zhi Jingyang Zhou Xiaoming Shi 2022The Innovation2022,3,2:2
9Decoupling engineering of formamidinium–cesium perovskites for efficient photovoltaics显示文摘Although pure formamidinium iodide perovskite(FAPbI3)possesses an optimal gap for photovoltaics,their poor phase stability limits the long-term operational stability of the devices.A promising approach to enhance their phase stability is to incorporate cesium into FAPbI3.However,state-of-the-art formamidinium–cesium(FA–Cs)iodide perovskites demonstrate much worse efficiency compared with FAPbI3,limited by the different crystallization dynamics of formamidinium and cesium,which result in poor composition homogeneity and high trap densities.We develop a novel strategy of crystallization decoupling processes of formamidinium and cesium via a sequential cesium incorporation approach.As such,we obtain highly reproducible,highly efficient and stable solar cells based on FA_(1–x)Cs_(x)PbI_(3)(x=0.05–0.16)films with uniform composition distribution in the nanoscale and low defect densities.We also revealed a new stabilization mechanism for Cs doping to stabilize FAPbI3,i.e.the incorporation of Cs into FAPbI3 significantly reduces the electron–phonon coupling strength to suppress ionic migration,thereby improving the stability of FA–Cs-based devices.Haoran Chen Yong Wang Yingping Fan Yuetian Chen Yanfeng Miao Zhixiao Qin Xingtao Wang Xiaomin Liu Kaicheng Zhu Feng Gao Yixin Zhao 2022National Science Review2022,9,10:1
10Biological distribution of ^(131)I-labeled anti-nucleus antigen monoclonal antibody chTNT in patients with pulmonary metastases from differentiated thyroid carcinoma显示文摘This work is to study the in vivo biological distribution of 131I-labeled mouse/human chimeric monoclonal antibody (131I-chTNT) in patients with pulmonary metastases from differentiated thyroid carcinoma. Ten patients with differentiated thyroid carcinoma were injected intravenously with a single dose of 131I-chTNT (5 MBq·kg-1 body weight). Radioactivity of blood and urine samples was measured at different time points. The in vivo stability and the metabolic status of 131I-chTNT were detected with supersaturated trichloroacetic acid. Continuous imaging was performed to outline the region of interest (ROI) and estimate the intake level on the whole body,major organs and tumor lesions at different time points. The serum time-radioactivity curve of 131I-chTNT accorded with the two-compartment model after a single intravenous injection: T1/2(h)=65.28±14.83,AUC0-t(MBq·h·mL-1)=8.93±1.32,AUC0-∞(MBq·h·mL-1)=10.58±2.19,and CL(mL·min-1·kg-1)=1635±359. The time-radioactivity percentage curve of 131I-chTNT urine excretion accorded with the one-compartment model after a single intravenous injection: T1/2(h)=99±10,and accumulative (31±9) % radioactivity of the injected dose was excreted in urine in one week. The percentages of serum 131I-chTNT in radioactive components at 24,48 and 72 h were over 95% and it was still (88±7) % at 168 h. As for chemical composition of radioactive substances in urine,radioactivity in urine samples originated from free 131I by 100%. Radioactivity of 131I-chTNT after intravenous administration was mainly concentrated in the lung and liver,least in the brain. Radioactivity of tumor tissues reached the maximum at 24 h and the tumor/normal tissue (T/N) ratio reached the maximum (1.28~3.83) during 3~7 d. The characteristics of in vivo biological distribution of 131I-chTNT in patients with pulmonary metastases from differentiated thyroid carcinoma are favorable for its therapeutic application for the metastasis tumors.MA Qingjie GAO Shi ZHAO Jie WEN Qiang BAI Lin ZHANG Haoran ZHAO Guoqing 2008Nuclear Science and Techniques2008,19,4:1
11Controllable two-dimensional Kerr and Raman–Kerr frequency combs in microbottle resonators with selectable dispersion显示文摘We report a broadband two-dimensional(2 D) Kerr and Raman–Kerr frequency comb generation in a silica bottle resonator accounting for azimuthal and axial degrees of freedom and pioneer a method that allows for controlled and reversible switching between a four wave mixing(FWM) state and a stimulated Raman scattering state. The repetition rate of the Raman–Kerr comb is not an integer number of the free spectral range, which spans more than 242 nm with hundreds of teeth. We show that, experimentally and numerically, multiple 2 D comb regimes can be selectively accessed via dispersion engineering by exciting different orders of axial modes or modifying the curvature of the axial profile, involving cascaded FWM, Raman lasing, and Raman-assisted FWM. The effect of axial curvature on dispersion is associated with the axial mode number in bottle resonators. Our approach enables dispersion and spectral engineering flexibility in any resonator with localized axial modes.XUEYING JIN XIN XU HAORAN GAO KEYI WANG HAOJIE XIA LIANDONG YU 2021Photonics Research2021,9,2:1

13The SACT Template:A Human Brain Diffusion Tensor Template for School-age Children显示文摘School-age children are in a specific development stage corresponding to juvenility,when the white matter of the brain experiences ongoing maturation.Dffusion-weighted magnetic resonance imaging(DWI),especially diffusion tensor imaging(DTI),is extensively used to characterize the maturation by assessing white matter properties in vivo.In the analysis of DWI data,spatial normalization is crucial for conducting inter-subject analyses or linking the individual space with the reference space.Using tensor-based registration with an appropriate diffusion tensor template presents high accuracy regarding spatial normalization.However,there is a lack of a standardized diffusion tensor template dedicated to school-age children with ongoing brain development.Here,we established the school-age children diffusion tensor(SACT)template by optimizing tensor reorientation on high-quality DTI data from a large sample of cognitively normal participants aged 6-12 years.With an age-balanced design,the SACT template represented the entire age range well by showing high similarity to the age-specific templates.Compared with the tensor template of adults,the SACT template revealed significantly higher spatial normalization accuracy and inter-subject coherence upon evaluation of subjects in two different datasets of schoolage children.A practical application regarding the age associations with the normalized DTI-derived data was conducted to further compare the SACT template and the adult template.Although similar spatial patterns were found,the SACT template showed significant effects on the distributions of the statistical results,which may be related to the performance of spatial normalization.Looking forward,the SACT template could contribute to future studies of white matter development in both healthy and clinical populations.The SACT template is publicly available now(tp://igshare com/aricles/dataseu'SACT_.template/14071283).Congying Chu Haoran Guan Sangma Xie Yanpei Wang Jie Luo Gai Zhao Zhiying Pan Mingming Hu Weiwei Men Shuping Tan Jia-Hong Gao Shaozheng Qin Yong He Lingzhong Fan Qi Dong Sha Tao 2022Neuroscience Bulletin2022,38,6:1
14Miniaturization of mechanical actuators in skin-integrated electronics for haptic interfaces显示文摘Skin-integrated electronics,also known as electronic skin(e-skin);are rapidly developing and are gradually being adopted in biomedical fields as well as in our daily lives.E-skin capable of providing sensitive and high-resolution tactile sensations and haptic feedback to the human body would open a new e-skin paradigm for closed-loop human-machine interfaces.Here,we report a class of materials and mechanical designs for the miniaturization of mechanical actuators and strategies for their integration into thin,soft e-skin for haptic interfaces.The mechanical actuators exhibit small dimensions of 5 mm diameter and 1.45 mm thickness and work in an electromagnetically driven vibrotactile mode with resonance frequency overlapping the most sensitive frequency of human skin.Nine mini actuators can be integrated simultaneously in a small area of 2 cm×2 cm to form a 3×3 haptic feedback array,which is small and compact enough to mount on a thumb tip.Furthermore,the thin,soft haptic interface exhibits good mechanical properties that work properly during stretching,bending,and twisting and therefore can conformally fit onto various parts of the human body to afford programmable tactile enhancement and Braille recognition with an accuracy rate over 85%.Dengfeng Li Jiahui He Zhen Song Kuanming Yao Mengge Wu Haoran Fu Yiming Liu Zhan Gao Jingkun Zhou Lei Wei Zhengyou Zhang Yuan Dai Zhaoqian Xie Xinge Yu 2021Microsystems & Nanoengineering2021,7,5:1

18Parallel System Based Quantitative Assessment and Self-evolution for Artificial Intelligence of Active Power Corrective Control显示文摘In artificial intelligence(AI)based-complex power system management and control technology,one of the urgent tasks is to evaluate AI intelligence and invent a way of autonomous intelligence evolution.However,there is,currently,nearly no standard technical framework for objective and quantitative intelligence evaluation.In this article,based on a parallel system framework,a method is established to objectively and quantitatively assess the intelligence level of an AI agent for active power corrective control of modern power systems,by resorting to human intelligence evaluation theories.On this basis,this article puts forward an AI self-evolution method based on intelligence assessment through embedding a quantitative intelligence assessment method into automated reinforcement learning(AutoRL)systems.A parallel system based quantitative assessment and self-evolution(PLASE)system for power grid corrective control AI is thereby constructed,taking Bayesian Optimization as the measure of AI evolution to fulfill autonomous evolution of AI under guidance of their intelligence assessment results.Experiment results exemplified in the power grid corrective control AI agent show the PLASE system can reliably and quantitatively assess the intelligence level of the power grid corrective control agent,and it could promote evolution of the power grid corrective control agent under guidance of intelligence assessment results,effectively,as well as intuitively improving its intelligence level through selfevolution.Tianyun Zhang Jun Zhang Feiyue Wang Peidong Xu Tianlu Gao Haoran Zhang Ruiqi Si 2024CSEE Journal of Power and Energy Systems2024,10,1:0

20Monitoring and early warning system of porcine pasteurellosis based on WebGIS显示文摘The incidence of porcine pasteurellosis in China is so widespread that it is difficult to clearly understand the prevalence and maintain continuous monitoring.In order to reduce immense negative economic impact on the livestock industry;monitoring,early warning,and visual management systems are highly desirable.In this study,a monitoring and early warning systemfor porcine pasteurellosis was established based onWeb Geographical Information System(WebGIS)technology.By establishing a path analysis function,buffer analysis function,and hot spot analysis function,it can provide a method of support and control of infectious diseases.For early warning of disease,four common interpolation methods were tested,all of which showed that the affected area of porcine pasteurellosis in China was mainly concentrated in the south of the mainland.A cross-validation method was used to compare the four interpolation methods.The cross-validation showed that the inverse distance weighting(IDW)method was suitable for forecasting the occurrence of porcine pasteurellosis in China.Finally,using C sharp(C#)as the development language and WebGIS technology,a monitoring and early warning system based on Browser/Server structure was developed.This is the first monitoring and early warning system of porcine pasteurellosis based onWebGIS.The performance of theWebGIS technology indicated a great potential for animal infectious disease applications and provided a foundation for future work.Zihan Zhu Haoran Wang Li Gao Xiang Gao Xinghua Meng Yao Xu Jianhua Xiao 2021Information Processing in Agriculture2021,8,1:0
