2The C_(6)D_(6)detector system on the Back-n beam line of CSNS显示文摘Introduction The neutron capture cross sections are very important in the field of nuclear device design and basic physics research.Hydrogen-free liquid scintillator such as C_(6)D_(6)detectors are widely used in the neutron capture cross-sectional measurements for the low neutron sensitivity and fast time response.The Back-n white neutron source at China Spallation Neutron Source is the first spallation white neutron source in China,and it is suitable for neutron capture cross-sectional measurement.Materials and methods A C_(6)D_(6)detector system was built in the Back-n experimental station.The pulse height weighting technique was used to determine the system’s detection efficiency.The response to gamma rays of the C_(6)D_(6)detector was measured,and the energy resolution function was determined.Monte Carlo simulation with Geant4 code was carried out to get the weighting function of this C_(6)D_(6)detector system.Additionally,the systematic uncertainty of the weighting function was also determined.Conclusion According to the experimental and simulation results,this C_(6)D_(6)detector system can be used to measure neutron capture cross section.Jie Ren Xichao Ruan Jie Bao Guangyuan Luan Wei Jiang Qi An Huaiyong Bai Ping Cao Qiping Chen Yonghao Chen Pinjing Cheng Zengqi Cui Ruirui Fan Changqing Feng Minhao Gu Fengqin Guo Changcai Han Zijie Han Guozhu He Yongcheng He Yuefeng He Hanxiong Huang Weiling Huang Xiru Huang Xiaolu Ji Xuyang Ji Haoyu Jiang Hantao Jing Ling Kang Mingtao Kang Bo Li Lun Li Qiang Li Xiao Li Yang Li Yang Li Rong Liu Shubin Liu Xingyan Liu Yinglin Ma Changjun Ning Binbin Qi Zhaohui Song Hong Sun Xiaoyang Sun Zhijia Sun Zhixin Tan Hongqing Tang Jingyu Tang Pengcheng Wang Qi Wang Taofeng Wang Yanfeng Wang Zhaohui Wang Zheng Wang Jie Wen Zhongwei Wen Qingbiao Wu Xiaoguang Wu Xuan Wu Likun Xie Yiwei Yang Han Yi Li Yu Tao Yu Yongji Yu Guohui Zhang Jing Zhang Linhao Zhang Liying Zhang Qingmin Zhang Qiwei Zhang Xianpeng Zhang Yuliang Zhang Zhiyong Zhang Yingtan Zhao Liang Zhou Zuying Zhou Danyang Zhu Kejun Zhu Peng Zhu 2019Radiation Detection Technology and Methods2019,3,3:1
3The machine protection system for CSNS显示文摘Background The China Spallation Neutron Source(CSNS)accelerator consists of an 80 MeV H-LINAC,a 1.6 GeV rapid cycling synchrotron(RCS)and two beam transport lines.The uncontrolled beam may permanently damage the components or lead to very high residual radiation dose along the beam line.So the equipment protection must be deliberately designed and implemented.Purpose The machine protection system(MPS)protects components from being damaged by the beam.The response time requirement for the CSNS MPS is less than 20 ms,so the PLC(programmable logic controller)was adopted to implement the interlock logic.Methods The MPS was implemented as a two-tier architecture system,and developed through utilizing PLC and Experimental Physics and Industrial Control System(EPICS)software toolkits.The application logic was taken into careful consideration during the implementation stage.An embedded CPU module can function as an IOC accessing PLC I/O modules through the sequence CPU,with an embedded Linux operation system.Results The interlock logic and heartbeat functions were tested with all functions ok.Time consumption has been measured thoroughly since the important requirement,which is around 15 ms to stop the beam.Conclusions MPS was completed in Sep.2017 and then put into operation.It has been operating smoothly for more than 3 years.MPS has played an important role in every stage of CSNS’s commissioning and operation and achieved high reliability during the user’s experiment operation.The accelerator recently runs stably with low equipment failure.Kang Mingtao Zhang Yuliang Jin Dapeng He Yongcheng Zhan Mingchuan Zhu Peng Wu Xuan Guo Fengqin Wang Lin 2021Radiation Detection Technology and Methods2021,5,2:1

6Turning a hot spot into a cold spot:polarization-controlled Fano-shaped local-field responses probed by a quantum dot显示文摘Optical nanoantennas can convert propagating light to local fields.The local-field responses can be engineered to exhibit nontrivial features in spatial,spectral and temporal domains,where local-field interferences play a key role.Here,we design nearly fully controllable local-field interferences in the nanogap of a nanoantenna,and experimentally demonstrate that in the nanogap,the spectral dispersion of the local-field response can exhibit tuneable Fano lineshapes with nearly vanishing Fano dips.A single quantum dot is precisely positioned in the nanogap to probe the spectral dispersions of the local-field responses.By controlling the excitation polarization,the asymmetry parameter q of the probed Fano lineshapes can be tuned from negative to positive values,and correspondingly,the Fano dips can be tuned across a broad spectral range.Notably,at the Fano dips,the local-field intensity is strongly suppressed by up to ~50-fold,implying that the hot spot in the nanogap can be turned into a cold spot.The results may inspire diverse designs of local-field responses with novel spatial distributions,spectral dispersions and temporal dynamics,and expand the available toolbox for nanoscopy,spectroscopy,nano-optical quantum control and nanolithography.Juan Xia Jianwei Tang Fanglin Bao Yongcheng Sun Maodong Fang Guanjun Cao Julian Evans Sailing He 2020Light(Science & Applications)2020,9,1:1

8Design and implementation of feedback logic of FOFB for HEPS显示文摘Purpose As a fourth-generation light source,High Energy Photon Source(HEPS)has much more stringent requirements to the beam orbit stability in both horizontal and vertical directions than the previous sources due to the much smaller beam sizes.Methods A Fast Orbit FeedBack(FOFB)system,with the closed-loop bandwidth around 500 Hz,is needed to meet the critical requirements.The latency of the FOFB system is the key to achieve these requirements.Results Proper design and implementation of the feedback logic to have low latency is illustrated in the paper.Calculation accuracy is kept in the whole operation except for the last-minute data translation into 32-bit floating point number.Daoyuan Wang Dapeng Jin Peng Zhu Zhexin Xie Lei Zeng Yuliang Zhang Yongcheng He 2023Radiation Detection Technology and Methods2023,7,3:0
9Correlation analysis of intestinal flora and pathological process of type 2 diabetes mellitus显示文摘Objective: To observe the relationship between the different stages of type 2 diabetes mellitus(T2DM)and the intestinal flora and verify its underlying mechanism.Methods: T2DM rats were generated by high-fat diet(HFD) combined with intraperitoneal streptozotocin(STZ) injection. The rats were divided into four groups: the control group(fed with normal feed for1 month), the HFD group(fed with HFD for 1 month), the T2DM group(HFD combined with STZ and blood glucose ≥11.1 m M), and the unformed T2DM model(Un-mod) group(HFD combined with STZ and blood glucose <11.1 m M). Feces were collected, and bacterial communities in the fecal samples were analyzed by 16S r RNA gene sequencing. The content of short-chain fatty acids(SCFAs) in feces was measured by gas chromatography. Western blot and quantitative real-time polymerase chain reaction were used to detect the expression of G protein-coupled receptor 41(GPR41) and GPR43.Results: At different stages of T2DM, the intestinal flora and SCFAs content of rats were significantly decreased(all P <.05). Our results indicated that g__Prevotella had a significant negative correlation, and g__Ruminococcus_torques_group and g__lachnoclastic had a significant positive correlation with blood glucose. The content of SCFAs, in particular acetate and butyrate, in rat feces of different stages of T2DM were significantly reduced, as well as GPR41 and GPR43 expression. The results in the Un-mod group were similar to the T2DM group, and the expression of GPR41 and GPR43 proteins were significantly higher than those in the T2DM group(both P <.001).Conclusion: The intestinal flora-SCFAs-GPR41/GPR43 network may be important in the development of T2DM. Decreasing blood glucose levels by regulating the intestinal flora may become a new therapeutic strategy for T2DM, which has very important clinical and social values.Yongcheng An Yuhui Duan Hongyu Dai Chen Wang Lu Shi Changhao He Yinglan Lv Huimin Li Shuhang Dai Baosheng Zhao 2022Journal of Traditional Chinese Medical Sciences2022,9,2:0
10Metabolomics characterization of Qingwei San on oral ulcer in db/db mice with stomach heat pattern显示文摘Objective:To characterize the effects of Qingwei San(QWS)on diabetic oral ulcer(OU)mice with stomach heat pattern through metabolomic analysis.Methods:A stomach heat pattern mouse model was established by treating C57BLKS/J Leprdb/db(db/db)mice with dried Zingiber officinale Rosc.rhizome(Z.officinale,Gan Jiang)decoction by gavage.All model mice had blood glucose levels of≥11.1 m M.Subsequently,OU was induced by Na OH cauterization.After 1 week of administration of QWS,non-targeted metabolomic analysis of serum was conducted using ultra high performance liquid chromatography coupled with mass spectrometry(UHPLC-MS/MS).Results:The non-targeted metabolomics results indicated that tryptophan metabolism,2-oxocarboxylic acid metabolism,serotonergic synapses,amino sugar and nucleotide sugar metabolism,and amino acid biosynthesis were involved in the therapeutic effects of QWS,with tryptophan metabolism playing a predominant role.Conclusion:QWS treatment can significantly improve the pathological status of diabetic OU mice with stomach heat pattern.QWS may regulate the release of inflammatory factors through the tryptophan metabolism pathway.Huimin Li Chen Wang Yinglan Lyu Lu Shi Changhao He Yongcheng An Huilin Zhang Hongbin Zhao Yonghua Zhao Baosheng Zhao 2023Journal of Traditional Chinese Medical Sciences2023,10,3:0
11Cleavable bimetallic-organic polymers for ROS mediated cascaded cancer therapy under the guidance of MRI through tumor hypoxia relief strategy显示文摘Despite recent advances in tumor treatment, reactive oxygen species(ROS)-mediated therapy, such as photodynamic therapy(PDT) and chemical dynamic therapy(CDT), remains challenging mainly due to hypoxia in tumor microenviroment. Relieving the hypoxia of tumor tissue has been considered as an attractive strategy for enhancing efficacy of ROS-based cancer treatment.Herein, one cascaded platform was developed to overcome tumor hypoxia and synergistically enhance the effect of ROSmediated therapy. This platform is based on cleavable bimetallic metal organic polymers(DOX@Fe/Mn-THPPTK-PEG). As an efficient Fenton-like material, it could not only produce cytotoxic ·OH by catalyzing the decomposition of intracellular H2O2, but also generate O2 to alleviate tumor hypoxia. In addition, the DOX-loaded metal organic polymers(MOPs could be disrupted after being exposed to laser irradiation or/and treated with H2O2, and then release the DOX for chemotherapy. Overall, 3 therapies(hypoxia-relieved PDT, photo-enhanced CDT, and ROS-mediated chemotherapy) could be achieved simultaneously by such a smart platform. Furthermore, T1-weighted MRI imaging ability of the MOPs could be greatly improved under H2O2 treatment.Therefore, total four robust functions were realized in a simple platform. These findings demonstrate great clinical potentials of the MOPs for cancer theranostics.Haozhe He Lihua Du Min Tan Yali Chen Liejing Lu Yongcheng An Yong Wang Xiaoxia Li Bo Li Jun Shen Jun Wu Xintao Shuai 2020Science China Chemistry2020,63,7:0
12The run management system for CSNS显示文摘Purpose In order to increase CSNS beam power from 100 to 500 kW,the linac injection energy needs to be increased from 80 to 300 MeV.The combined layout of superconducting spoke cavities and elliptical cavities will be adopted to accelerate H−beam to 300 MeV.In this paper,a compact single spoke cavity withΦ50-mm beam aperture was proposed,with the RF performance of the spoke cavity optimized to Ep/Eacc<5,Bp/Eacc<9,as well as the good multipacting behavior.Methods CST Microwave Studio was used to optimize the RF performance(Epeak/Eacc,Bpeak/Eacc,R/Q)with cavity geometry parameters.After electromagnetic design was finished,multipacting behavior was studied with CST Particle Studio module,and cavity shape modification was made to get a reasonablevalue.Results The simulation got optimum results of Epeak/Eacc=4.97 and Bpeak/Eacc=8.42 mT/(MV/m),and themax is 1.52 at Eacc=7.74 MV/m.Conclusion A 648 MHzβg=0.4 single spoke cavity with beam apertureΦ50 mm was proposed in the paper.This compact cavity may be a very promising option for CSNS linac upgrading.In addition to the optimization of the RF parameters,the multipacting behavior of the cavity is also studied,and cavity shape is optimized to reducevalue.Yuliang Zhang Mingtao Kang Dapeng Jin Yongcheng He Peng Zhu Xuan Wu Fengqin Guo Lin Wang Wenchun Gao Gang Li 2019Radiation Detection Technology and Methods2019,3,3:0

14Wearable ultrasensitive and rapid human physiological monitoring based on microfiber Sagnac interferometer显示文摘High-sensitive and fast-responding flexible strain sensors are essential for the smart wearable devices that precisely and dynamically perceive the weak deformations induced by human physiological signals.Here,a flexible strain sensor via polydimethylsiloxane(PDMS)-encapsulated microfiber Sagnac interferometer was designed and prepared for monitoring the human pulse signals and sound vibrations.The sensor achieved a record-breaking sensitivity(gauge factor,GF=9977)and an extremely low detection limit(0.00025%)due to the strong polarization-dependent coupling effect in the microfiber coupler and the polarization-mixing effect in the Sagnac loop.The relative intensity demodulation method also enabled a fast response time of 10μs.The wearable pulse measurements were implemented by attaching this flexible strain sensor directly to human skin at various locations and the waveform details were accurately captured.Taking advantage of the ultra-high sensitivity and fast response performance of the prepared sensor,the real-time dynamic acquisition of the underwater weak signal,such as the hydro-acoustic waves with a wide range of 20 Hz–16.86 k Hz,has been demonstrated.These initial results pave the way for a new and innovative category of underwater wearable devices with rapid detection of human physiological signals and weak environmental vibrations.Xin WANG Hongyou ZHOU Meihua CHEN Yongcheng HE Zhishen ZHANG Jiulin GAN Zhongmin YANG 2024Science China(Information Sciences)2024,67,3:0
15Mulberry leaf flavonoids activate BAT and induce browning of WAT to improve type 2 diabetes via regulating the AMPK/SIRT1/PGC-1α signaling pathway显示文摘Mulberry (Morus alba L.) leaf is a well-established traditional Chinese botanical and culinary resource. It has found widespread application in the management of diabetes. The bioactive constituents of mulberry leaf, specifically mulberry leaf flavonoids (MLFs), exhibit pronounced potential in the amelioration of type 2 diabetes (T2D). This potential is attributed to their ability to safeguard pancreatic β cells, enhance insulin resistance, and inhibit α-glucosidase activity. Our antecedent research findings underscore the substantial therapeutic efficacy of MLFs in treating T2D. However, the precise mechanistic underpinnings of MLF’s anti-T2D effects remain the subject of inquiry. Activation of brown/beige adipocytes is a novel and promising strategy for T2D treatment. In the present study, our primary objective was to elucidate the impact of MLFs on adipose tissue browning in db/db mice and 3T3-L1 cells and elucidate its underlying mechanism. The results manifested that MLFs reduced body weight and food intake, alleviated hepatic steatosis, improved insulin sensitivity, and increased lipolysis and thermogenesis in db/db mice. Moreover, MLFs activated brown adipose tissue (BAT) and induced the browning of inguinal white adipose tissue (IWAT) and 3T3-L1 adipocytes by increasing the expressions of brown adipocyte marker genes and proteins such as uncoupling protein 1 (UCP1) and beige adipocyte marker genes such as transmembrane protein 26 (Tmem26), thereby promoting mitochondrial biogenesis. Mechanistically, MLFs facilitated the activation of BAT and the induction of WAT browning to ameliorate T2D primarily through the activation of AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling pathway. These findings highlight the unique capacity of MLF to counteract T2D by enhancing BAT activation and inducing browning of IWAT, thereby ameliorating glucose and lipid metabolism disorders. As such, MLFs emerge as a prospective and innovative browning agent for the treatment of T2D.CHENG Long SHI Lu HE Changhao WANG Chen LV Yinglan LI Huimin AN Yongcheng DUAN Yuhui DAI Hongyu ZHANG Huilin HUANG Yan FU Wanxin SUN Weiguang ZHAO Baosheng 2023Chinese Journal of Natural Medicines2023,21,11:0
