1Performance Evaluation for Medium Voltage MIMO-OFDM Power Line Communication System显示文摘Power line communication(PLC)provides intelligent electrical functions such as power quality measurement,fault surveys,and remote control of electrical network.Most of research works have been done in low voltage(LV)scenario due to the fast development of in-home PLC.The aim of this paper is to evaluate the link-level performance of a medium voltage(MV)MIMO-OFDM communication system based on transmission link under underground power line channel.The MIMO channel is modeled as a modified multipath model in the presence of impulsive noise and background noise.We first perform a measurement on the practical MV MIMO channel parameters for a section of buried cable of 1 km long in Ganzhou city,Jiangxi province,China.Based on the measured channel,we design the frame structure based on an IEEE standard for broadband over power line networks[1]to support MV MIMO-OFDM transmission.According to designed frame structure,we design an encoder and a decoder for a dual binary tail-biting turbo code and optimize some key decoder parameters for low bit error rate performance.Finally,the link-level performance for both spatial multiplexing and spatial diversity are evaluated.Numeral results show that MV MIMO-OFDM is a promising approach to provide both high data rate and link reliability for PLC.Yingxue Li Min Zhang Wenguang Zhu Mengyuan Cheng Cheng Zhou Yongpeng Wu 2020China Communications2020,17,1:10

3Preparation of DHA-and EPA-enriched Glycerides by Enzymatic Interesterification Using Tuna Oil and Capric Acid显示文摘This study focused on the preparation of docosahexaenoic acid(DHA) and eicosapentaenoic acid(EPA)enriched-triacylglycerols by enzymatic interesterification using tuna oil and capric acid. The content of DHA+EPA is 26.86% in the tuna oil used in this study. A response surface methodology(RSM) was used to optimize the reaction parameters(reaction temperature, substrate molar ratio, enzyme amount and reaction time), and the optimized conditions were determined to be: reaction temperature 58℃, substrate molar ratio(capric acid : tuna oil) 4:1, enzyme amount 4%, and reaction time 7.5 h. Under the optimized conditions, the content of DHA+EPA in the glycerides was 40.03%, which is 13.17% higher than that in raw tuna oil. In addition,the MLM-type structured lipids containing medium chain fatty acids(capric acid) at positions sn-1,3 and a long chain fatty acid(DHA/EPA) at the position sn-2 may have many health benefits for humans.LIANG Shaohua WANG Mengyuan ZHU Lijie ZHANG Man YANG Ming 2018Grain & Oil Science and Technology2018,1,2:4
4New insights into eutrophication management:Importance of temperature and water residence time显示文摘Eutrophication and harmful cyanobacterial blooms threaten water resources all over the world.There is a great controversy about controlling only phosphorus or controlling both nitrogen and phosphorus in the management of lake eutrophication.The primary argument against the dual nutrients control of eutrophication is that nitrogen fixation can compensate the nitrogen deficits.Thus,it is of great necessary to study the factors that can significantly affect the nitrogen fixation.Due to the difference of climate and human influence,the water quality of different lakes(such as water temperature,N:P ratio and water residence time)is also quite different.Numerous studies have reported that the low N:P ratio can intensify the nitrogen fixation capacities.However,the effects of temperature and water residence time on the nitrogen fixation remain unclear.Thus,30 shallows freshwater lakes in the eastern plain of China were selected to measure dissolved N_(2) and Ar concentrations through N_(2):Ar method using a membrane inlet mass spectrometer to quantify the nitrogen fixation capacities and investigate whether the temperature and water residence time have a great impact on nitrogen fixation.The results have shown that the short lake water residence time can severely inhibit the nitrogen fixation capacities through inhibiting the growth of nitrogenfixing cyanobacteria,changing the N:P ratio and resuspending the solids from sediments.Similarly,lakes with low water temperature also have a low nitrogen fixation capacity,suggesting that controlling nitrogen in such lakes is feasible if the growth of cyanobacteria is limited by nitrogen.Feng Zhao Xu Zhan Hai Xu Guangwei Zhu Wei Zou Mengyuan Zhu Lijuan Kang Yulong Guo Xingchen Zhao Zicong Wang Wei Tang 2022Journal of Environmental Sciences2022,34,1:2

6Ultrathin NiFeS nanosheets as highly active electrocatalysts for oxygen evolution reaction显示文摘The development of efficient and cost-effective oxygen evolution reaction(OER)electrocatalysts is crucial for clean energy conversion and storage devices,such as water-splitting,CO_(2) reduction,and metalair batteries.Herein,we report an efficient 2-dimensional OER catalyst of ultrathin nickel-iron sulfide nanosheets(Ni Fe S-NS).Dodecanethiol is employed in the synthesis,which prohibits the growth along the Z-axis,thus a nanosheet is obtained.The Ni Fe S-NS shows high OER catalytic activity,which only requires a small overpotential of 273 mV to achieve the OER current density of 10 mA/cm^(2) in alkaline electrolyte,and almost no decay after 150 h of chronopotentiometry test.The high performance is attributed to the 2-dimensional structure,the synergistic effect from the Ni and Fe components which promotes the formation of the high valence Ni species,and the tuning effect from the in-situ generated sulfate doping.This work demonstrates the advantages of the 2-dimensional sulfides in electrocatalysis.Yanrong Xue Mengyuan Liu Yangyuanxiang Qin Yufeng Zhang Xuejiang Zhang Jinjie Fang Xu Zhang Wei Zhu Zhongbin Zhuang 2022Chinese Chemical Letters2022,33,8:2

9Cholesterol-associated lysosomal disorder triggers cell death of hematological malignancy:Dynamic analysis on cytotoxic effects of LW-218显示文摘The integrity of lysosomes is of vital importance to survival of tumor cells.We demonstrated that LW-218,a synthetic flavonoid,induced rapid lysosomal enlargement accompanied with lysosomal membrane permeabilization in hematological malignancy.LW-218-induced lysosomal damage and lysosome-dependent cell death were mediated by cathepsin D,as the lysosomal damage and cell apoptosis could be suppressed by depletion of cathepsin D or lysosome alkalization agents,which can alter the activity of cathepsins.Lysophagy,was initiated for cell self-rescue after LW-218 treatment and correlated with calcium release and nuclei translocation of transcription factor EB.LW-218 treatment enhanced the expression of autophagy-related genes which could be inhibited by intracellular calcium chelator.Sustained exposure to LW-218 exhausted the lysosomal capacity so as to repress the normal autophagy.LW-218-induced enlargement and damage of lysosomes were triggered by abnormal cholesterol deposition on lysosome membrane which caused by interaction between LW-218 and NPC intracellular cholesterol transporter 1.Moreover,LW-218 inhibited the leukemia cell growth in vivo.Thus,the necessary impact of integral lysosomal function in cell rescue and death were illustrated.Po Hu Hui Li Wenzhuo Sun Hongzheng Wang Xiaoxuan Yu Yingjie Qing Zhanyu Wang Mengyuan Zhu Jingyan Xu Qinglong Guo Hui Hui 2021Acta Pharmaceutica Sinica B2021,11,10:1
10A review of the application of machine learning in water quality evaluation显示文摘With the rapid increase in the volume of data on the aquatic environment,machine learning has become an important tool for data analysis,classification,and prediction.Unlike traditional models used in water-related research,data-driven models based on machine learning can efficiently solve more complex nonlinear problems.In water environment research,models and conclusions derived from machine learning have been applied to the construction,monitoring,simulation,evaluation,and optimization of various water treatment and management systems.Additionally,machine learning can provide solutions for water pollution control,water quality improvement,and watershed ecosystem security management.In this review,we describe the cases in which machine learning algorithms have been applied to evaluate the water quality in different water environments,such as surface water,groundwater,drinking water,sewage,and seawater.Furthermore,we propose possible future applications of machine learning approaches to water environments.Mengyuan Zhu Jiawei Wang Xiao Yang Yu Zhang Linyu Zhang Hongqiang Ren Bing Wu Lin Ye 2022Eco-Environment & Health2022,1,2:1

12Consensus on potential biomarkers developed for use in clinical tests for schizophrenia显示文摘Background Schizophrenia is a serious mental illness affecting approximately 20 million individuals globally.Both genetic and environmental factors contribute to the illness.If left undiagnosed and untreated,schizophrenia results in impaired social function,repeated hospital admissions,reduced quality of life and decreased life expectancy.Clinical diagnosis largely relies on subjective evidence,including self-reported experiences,and reported behavioural abnormalities followed by psychiatric evaluation.In addition,psychoses may occur along with other conditions,and the symptoms are often episodic and transient,posing a significant challenge to the precision of diagnosis.Therefore,objective,specific tests using biomarkers are urgently needed for differential diagnosis of schizophrenia in clinical practice.Aims We aimed to provide evidence-based and consensus-based recommendations,with a summary of laboratory measurements that could potentially be used as biomarkers for schizophrenia,and to discuss directions for future research.Methods We searched publications within the last 10 years with the following keywords:‘schizophrenia’,‘gene’,‘inflammation’,‘neurotransmitter’,‘protein marker’,‘gut microbiota’,‘pharmacogenomics’and‘biomarker’.A draft of the consensus was discussed and agreed on by all authors at a round table session.Results We summarised the characteristics of candidate diagnostic markers for schizophrenia,including genetic,inflammatory,neurotransmitter,peripheral protein,pharmacogenomic and gut microbiota markers.We also proposed a novel laboratory process for diagnosing schizophrenia in clinical practice based on the evidence summarised in this paper.Conclusions Further efforts are needed to identify schizophrenia-specific genetic and epigenetic markers for precise diagnosis,differential diagnosis and ethnicity-specific markers for the Chinese population.The development of novel laboratory techniques is making it possible to use these biomarkers clinically to diagnose disease.Ping Lin Junyu Sun Xiaoyan Lou Dan Li Yun Shi Zhenhua Li Peijun Ma Ping Li Shuzi Chen Weifeng Jin Shuai Liu Qing Chen Qiong Gao Lili Zhu Jie Xu Mengyuan Zhu Mengxia Wang Kangyi Liang Ling Zhao Huabin Xu Ke Dong Qingtian Li Xunjia Cheng Jinghong Chen Xiaokui Guo 2022General Psychiatry2022,35,1:1
13Autocatalytic reduction-assisted synthesis of segmented porous PtTe nanochains for enhancing methanol oxidation reaction显示文摘Morphology engineering has been developed as one of the most widely used strategies for improving the performance of electrocatalysts.However,the harsh reaction conditions and cumbersome reaction steps during the nanomaterials synthesis still limit their industrial applications.Herein,one-dimensional(1D)novel-segmented PtTe porous nanochains(PNCs)were successfully synthesized by the template methods assisted by Pt autocatalytic reduction.The PtTe PNCs consist of consecutive mesoporous architectures that provide a large electrochemical surface area(ECSA)and abundant active sites to enhance methanol oxidation reaction(MOR).Furthermore,1D nanostructure as a robust sustaining frame can maintain a high mass/charge transfer rate in a long-term durability test.After 2,000 cyclic voltammetry(CV)cycles,the ECSA value of PtTe PNCs remained as high as 44.47 m^(2)·gPt^(-1),which was much larger than that of commercial Pt/C(3.95 m^(2)·gPt^(-1)).The high catalytic activity and durability of PtTe PNCs are also supported by CO stripping test and density functional theory calculation.This autocatalytic reduction-assisted synthesis provides new insights for designing efficient low-dimensional nanocatalysts.Qiqi Zhang Tianyu Xia He Huang Jialong Liu Mengyuan Zhu Hao Yu Weifeng Xu Yuping Huo Congli He Shipeng Shen Cong Lu Rongming Wang Shouguo Wang 2023Nano Research Energy2023,2,1:1
14Kidney organoids as a promising tool in nephrology显示文摘Kidney disease has become a global public health problem affecting over 750 million people worldwide and imposing a heavy economic burden on patients.The complex architecture of the human kidney makes it very difficult to study the pathophysiology of renal diseases in vitro and to develop effective therapeutic options for patients.Even though cell lines and animal models have enriched our understanding,they fail to recapitulate key aspects of human kidney development and renal disease at cellular and functional levels.Organoids can be derived from either pluripotent stem cells or adult stem cells by strictly regulating key signalling pathways.Today,these self-differentiated organoids represent a promising technology to further understand the human kidney,one of the most complex organs,in an unprecedented way.The newly established protocols improved by organ-on-chip and coculture with immune cells will push kidney organoids towards the next generation.Herein,we focus on recent achievements in the application of kidney organoids in disease modelling,nephrotoxic testing,precision medicine,biobanking,and regenerative therapy,followed by discussions of novel strategies to improve their utility for biomedical research.The applications we discuss may help to provide new ideas in clinical fields.Mengyuan Wu Tingting Hu Ping Zhu Moussa Ide Nasser Jie Shen Fang Sun Qingnan He Mingyi Zhao 2022Genes & Diseases2022,9,3:1

16Magnetoresistance anomaly in Fe_(5)GeTe_(2)homo-junctions induced by its intrinsic transition显示文摘Two-dimensional van der Waals(2D vdW)magnets have attracted great attention recently and possess the unprecedented advantages of incorporating high-quality vdW heterostructures and homostructures into spintronic devices,and exploring various physical phenomena or technologies.Among them,Fe_(5)GeTe_(2)(F5GT)has ferromagnetic order close to room temperature,however the magnetic properties near its intrinsic transitions and F5GT-based 2D devices remain mostly unexplored.Here,we systematically demonstrate the peculiar magnetic properties of Fe_(5)GeTe_(2)nanoflakes near its intrinsic transition temperature(Tp)which is far lower than its Curie temperature(TC)of~265 K,and firstly discover anomalous magnetoresistance effect in F5GT homo-junctions by magneto-transport measurements.The strongest anomalous Hall effect occurs around Tp which is located in a temperature range from 130 to 160 K for the F5GT nanoflakes with different thicknesses.Furthermore,negative magnetoresistance(N-MR)and butterfly-shaped magnetoresistance(B-MR)are observed in F5GT homo-junction devices,and they appeared only in an intermediate temperature range from 110 to 160 K,noticeably showing the maxima near the T_(p)rather than the lowest temperature.Our experimental results clearly reveal the significant influence of intrinsic transitions on magnetic properties of F5GT and magnetoresistance effect in F5GT homo-junction devices,which imply a new strategy to achieve highperformance 2D spintronic devices by tuning intrinsic magnetic or structural transitions in 2D vdW magnets.Ruijie Zhao Yanfei Wu Shaohua Yan Xinjie Liu He Huang Yang Gao Mengyuan Zhu Jianxin Shen Shipeng Shen Weifeng Xu Zeyu Zhang Liyuan Zhang Jingyan Zhang Xinqi Zheng Hechang Lei Ying Zhang Shouguo Wang 2023Nano Research2023,16,7:0
17An Experimental Study on Oxidized Mercury Adsorption by Bromide Blended Coal Combustion Fly Ash显示文摘The application of forced mercury oxidation technology would lead to an increase of Hg^(2+)concentration in the flue gas.Although Hg^(2+)can be easily removed in the WFGD,the mercury re-emission in the WFGD can decrease the total removal of mercury from coal-fired power plants.Hence,it is necessary to control Hg^(2+)concentration in the devices before the WFGD.Fly ash adsorbent is considered as a potential alternative for commercial activated carbon adsorbent.However,the adsorption efficiency of the original fly ash is low.Modification procedure is needed to enhance the adsorption performance.In this study,the adsorption of Hg^(2+)by brominated fly ash was studied.The fly ash was collected from the full-scale power plant utilizing bromide-blended coal combustion technology.The brominated fly ash exhibited excellent performance for Hg^(2+)removal.The flue gas component HBr and SO_(2)could improve adsorbent’s performance,while HCl would hinder its adsorption process.Also,it was demonstrated by Hg-TPD experiments that the adsorbed Hg^(2+)mainly existed on the fly ash surface in the form of HgBr_(2).In summary,the brominated fly ash has a broad application prospect for mercury control.Mingyu Yu Mengyuan Liu Guangqian Luo Ruize Sun Jingyuan Hu Hailu Zhu Li Zhong Lipeng Han Xian Li Hong Yao 2021Energy Engineering2021,118,5:0

19Therapeutic application of chick early amniotic fluid: effective rescue of acute myocardial ischemic injury by intravenous administration显示文摘Myocardial regeneration has been considered a promising option for the treatment of adult myocardial injuries.Previously,a chick early amniotic fluid(ceAF)preparation was shown to contain growth-related factors that pro-moted embryonic growth and cellular proliferation,though the nature of the components within ceAF were not fully defined.Here we tested whether this ceAF preparation is similarly effective in the promotion of myocardial regen-eration,which could provide an alternative therapeutic for intervening myocardial injury.In this study,a myocardial ischemic injury model was established in adult mice and pigs by multiple research entities,and we were able to show that ceAF can efficiently rescue damaged cardiac tissues and markedly improve cardiac function in both experimental models through intravenous administration.ceAF administration increased cell proliferation and improved angio-genesis,likely via down-regulation of Hippo-YAP signaling.Our data suggest that ceAF administration can effectively rescue ischemic heart injury,providing the key functional information for the further development of ceAF for use in attenuating myocardial injury.Baiping Cui Yufan Zheng Xiang Gao Lihong Zhang Borui Li Jia Chen Xinyan Zhou Mengyuan Cai Wenrui Sun Yuting Zhang Keejong Chang Jiayi Xu Fuyin Zhu Yan Luo Tao Sun Jin Qian Ning Sun 2022Cell Regeneration2022,11,1:0
20Negative Isolation of Circulating Tumor Cells Using a Microfluidic Platform Integrated with Streptavidin-Functionalized PLGA Nanofibers显示文摘Detection of circulating tumor cells(CTCs)plays an important role in early diagnosis of cancer and personalized therapy.However,isolated CTCs,especially those captured by positive sorting methods,are difficult to culture in subsequent assays because the cells have to be labeled or attached to a substrate for separation.In this study,a negative sorting method has been developed for isolation of CTCs through a microfluidic platform integrated with streptavidin-functionalized electro-spun polylactic-co-glycolic acid nanofibers.Through the specific biotin-streptavidin interaction,the device is able to sort out biotinylated anti-CD45 antibody-labeled white blood cells(WBCs)and enrich A549 human cancer cells from the blood or CTCs from patient suffering non-small cell lung cancer.We demonstrate that the WBC capture efficiency is as high as 97.0%,and the recovery rate of cancer cells reaches up to 97.5%.CTCs are enumerated from blood samples of patients suf-fering lung carcinoma.The number of CTCs increased with the progression of NCCN TNM stages and showed statistically significant difference between stage I and later stages.These results suggest that the integrated negative sorting device is promising to be used for diagnosis of cancer.Mengyuan Wang Yulong Tan Du Li Gangwei Xu Di Yin Yunchao Xiao Tiegang Xu Xiaofeng Chen Xiaoyue Zhu Xiangyang Shi 2021Advanced Fiber Materials2021,3,3:0
