| 2 | Effect of Peak Power and Pulse Width on Coherent Doppler Wind Lidar’s SNR显示文摘The laser device is the core component of coherent Doppler wind lidar.The peak power and pulse width of laser transmitting pulse have important effects on SNR.Based on coherent Doppler wind pulse lidar,the peak power and pulse width influence on SNR is studied on the theoretical derivation and analysis,and the results show that the higher the peak power can realize the greater the signal-to-noise ratio of coherent Doppler wind lidar.But when the peak power is too large,the laser pulse may appear nonlinear phenomenon,which cause the damage of the laser.So,the peak power must be less than the stimulated brillouin scattering power threshold.Increasing the pulse width can make the laser device to output more energy,but it will also make the spatial resolution lower,and the influence of turbulence on SNR will be greater.After a series of simulation analyses,it can be concluded that when the peak power is 650W and the pulse width is 340ns,the SNR of the system can be maximized.In addition,the coherent Doppler wind lidar system is set up to carry out corresponding experimental verification.The experimental results are consistent with the theoretical analysis and simulation,which verifies the correctness of the theoretical analysis and simulation results.It provides theoretical basis and practical ex-perience for the design of laser transmitting pulse in coherent Doppler wind lidar system. | REN Yong WU Xuefei TAO Fa CAO Haishuai | 2022 | Instrumentation2022，9，2： | 4 |
| 3 | Recent advances in isolation,identification,and culture of mammalian spermatogonial stem cells显示文摘Continuous spermatogenesis depends on the self-renewal and differentiation of spermatogonial stem cells(SSCs).SSCs,the only male reproductive stem cells that transmit genetic material to subsequent generations,possess an inherent self-renewal ability,which allows the maintenance of a steady stem cell pool.SSCs eventually differentiate to produce sperm.However,in an in vitro culture system,SSCs can be induced to differentiate into various types of germ cells.Rodent SSCs are well defined,and a culture system has been successfully established for them.In contrast,available information on the biomolecular markers and a culture system for livestock SSCs is limited.This review summarizes the existing knowledge and research progress regarding mammalian SSCs to determine the mammalian spermatogenic process,the biology and niche of SSCs,the isolation and culture systems of SSCs,and the biomolecular markers and identification of SSCs.This information can be used for the effective utilization of SSCs in reproductive technologies for large livestock animals,enhancement of human male fertility,reproductive medicine,and protection of endangered species. | Hua-Ming Xi Yi-Jie Ren Fa Ren Yu Li Tian-Yu Feng Zhi Wang Ye-Qing Du Li-Kun Zhang Jian-Hong Hu | 2022 | Asian Journal of Andrology2022，24，1： | 2 |
| 4 | Computer simulation studies on the interactions between nanoparticles and cell membrane显示文摘In recent times,nanoparticles(NPs)have received intense attention not only due to their potential applications as a candidate for drug delivery,but also because of their undesirable effects on human health.Although extensive experimental studies have been carried out in literature in order to understand the interaction between NPs and a plasma membrane,much less is known about the molecular details of the interaction mechanisms and pathways.As complimentary tools,coarse grained molecular dynamics(CGMD)and dissipative particle dynamics(DPD)simulations have been extensively used on the interaction mechanism and evolution pathway.In the present review we summarize computer simulation studies on the NP-membrane interaction,which developed over the last few years,and particularly evaluate the results from the DPD technique.Those studies undoubtedly deepen our understanding of the NP-membrane interaction mechanisms and provide a design guideline for new NPs. | TIAN Fa Lin YUE Tong Tao LI Ye ZHANG Xian Ren | 2014 | Science China Chemistry2014，57，12： | 2 |
| 5 | TLR7/8 signalling affects X-sperm motility via the GSK3α/β-hexokinase pathway for the efficient production of sexed dairy goat embryos显示文摘Background:Goat milk is very similar to human milk in terms of its abundant nutrients and ease of digestion.To derive greater economic benefit,farmers require more female offspring(does);however,the buck-to-doe offspring sex ratio is approximately 50%.At present,artificial insemination after the separation of X/Y sperm using flow cytometry is the primary means of controlling the sex of livestock offspring.However,flow cytometry has not been successfully utilised for the separation of X/Y sperm aimed at sexing control in dairy goats.Results:In this study,a novel,simple goat sperm sexing technology that activates the toll-like receptor 7/8(TLR7/8),thereby inhibiting X-sperm motility,was investigated.Our results showed that the TLR7/8 coding goat Xchromosome was expressed in approximately 50%of round spermatids in the testis and sperm,as measured from cross-sections of the epididymis and ejaculate,respectively.Importantly,TLR7/8 was located at the tail of the Xsperm.Upon TLR7/8 activation,phosphorylated forms of glycogen synthase kinaseα/β(GSK3α/β)and nuclear factor kappa-B(NF-κB)were detected in the X-sperm,causing reduced mitochondrial activity,ATP levels,and sperm motility.High-motility Y-sperm segregated to the upper layer and the low-motility X-sperm,to the lower layer.Following in vitro fertilisation using the TLR7/8-activated sperm from the lower layer,80.52±6.75%of the embryos were XX females.The TLR7/8-activated sperm were subsequently used for in vivo embryo production via the superovulatory response;nine embryos were collected from the uterus of two does that conceived.Eight of these were XX embryos,and one was an XY embryo.Conclusions:Our study reveals a novel TLR7/8 signalling mechanism that affects X-sperm motility via the GSK3α/β-hexokinase pathway;this technique could be used to facilitate the efficient production of sexed dairy goat embryos. | Fa Ren Huaming Xi Yijie Ren Yu Li Fei Wen Ming Xian Mengjie Zhao Dawei Zhu Liqiang Wang Anmin Lei Jianhong Hu | 2022 | Journal of Animal Science and Biotechnology2022，13，2： | 2 |

| 13 | Tire Road Friction Coefficient Estimation:Review and Research Perspectives显示文摘Many surveys on vehicle traffic safety have shown that the tire road friction coefficient(TRFC)is correlated with the probability of an accident.The probability of road accidents increases sharply on slippery road surfaces.Therefore,accurate knowledge of TRFC contributes to the optimization of driver maneuvers for further improving the safety of intelligent vehicles.A large number of researchers have employed different tools and proposed different algorithms to obtain TRFC.This work investigates these different methods that have been widely utilized to estimate TRFC.These methods are divided into three main categories:off-board sensors-based,vehicle dynamics-based,and data-driven-based methods.This review provides a comparative analysis of these methods and describes their strengths and weaknesses.Moreover,some future research directions regarding TRFC estimation are presented. | Yan Wang Jingyu Hu Fa’an Wang Haoxuan Dong Yongjun Yan Yanjun Ren Chaobin Zhou Guodong Yin | 2022 | Chinese Journal of Mechanical Engineering2022，35，2： | 1 |

| 16 | Measurement of Br(n,γ)cross sections up to stellar s-process temperatures at the CSNS Back‑n显示文摘The neutron capture cross sections(n,γ)of bromine were obtained using the time-of-flight technique at the Back-n facility of the China Spallation Neutron Source.Promptγ-rays originating from neutron-induced capture events were detected using four C_(6)D_(6) detectors.The pulse-height weighting technique and double-bunch unfolding method based on Bayesian theory were used in the data analysis.Background deductions,normalization,and corrections were carefully considered to obtain reliable measurement results.The multilevel R-matrix Bayesian code SAMMY was used to extract the resonance parameters in the resolved resonance region(RRR).The average cross sections in the unresolved resonance region(URR)were obtained from 10 to 400 keV.The experimental results were compared with data from several evaluated libraries and previous experi-ments in the RRR and URR.The TALYS code was used to describe the average cross sections in the URR.The astrophysical Maxwell average cross sections(MACSs)of ^(79,81)Br from kT=5 to 100 keV were calculated over a sufficiently wide range of neutron energies.At a thermal energy of kT=30 keV,the MACS value for ^(79)Br 682±68 mb was in good agreement with the KADoNiS v1.0 recommended value.By contrast,the value of 293±29 mb for ^(81)Br was substantially higher than that of the evaluated database and the KADoNiS v1.0 recommended value. | Gao‑Le Yang Zhen‑Dong An Wei Jiang Xian‑Kai Li Wei‑Wei Qiu Zheng‑Fa Liao Zi‑Yue Zhuang Xiao‑Ping Zhang Sheng‑Li Chen Chen‑Chen Guo Er‑Xi Xiao Xiao Fang Xin‑Xiang Li Xin‑Rong Hu Bing Jiang Jin‑Cheng Wang Jie Ren Wen Luo Zhi‑Chao Zhu Hao‑Yang Lan Zong‑Wei Cao Xu Ma Ying‑Du Liu Pu‑Sen Wang Yi Yang Ping Su Xian‑Gai Deng Wan‑Bing He Chun‑Wang Ma Yu‑Ting Wang Zhi‑Tao Dai Peng‑Qin He Ren‑Guang Tang Tao Zhou Jing Wang Han Yi Yue Zhang Yong‑Hao Chen Rui‑Rui Fan Ke‑Qing Gao Qiang Li Kang Sun Zhi‑Xin Tan Min‑Hao Gu Han‑Tao Jing Jing‑Yu Tang | 2023 | Nuclear Science and Techniques2023，34，11： | 0 |
| 17 | Evaluation of Wheat Stripe Rust Resistance in Sichuan Province显示文摘Wheat stripe rust,caused by Puccinia striiformis Westend. f. sp. tritici Erikss.( Pst),is one of the most destructive diseases of wheat( Triticum aestivum L.) worldwide. Sichuan province plays an important role in stripe rust epidemic in China. To identify and evaluate wheat stripe rust resistance in Sichuan Province,134 wheat cultivars( lines) were inoculated with seven Pst races at seedling stage and adult stage. The results indicated that the resistance frequencies of wheat cultivars( lines) against seven races CYR31,Su11-7,CYR29,Su11-4,CYR32,CYR33 and V26 were 92. 4%,92. 5%,89. 3%,89. 4%,87. 3%,85. 0% and 82. 8%,respectively. Among 134 materials,76( 56. 0%) performed resistance against all tested races both in seedling and adult stages. The virulence of new pathogenic type V26 of Pst on wheat cultivars( lines) was stronger than the dominant races CYR32 and CYR33. All wheat cultivars( lines) were classified into three types according to analysis of resistance spectrum; 66. 4% of cultivars( lines) showed all-stage resistance,17. 9% were adult-plant resistance,and 15. 7% were susceptible. This indicated that although the overall resistance level of wheat cultivars( lines) in Sichuan Province was very high,the resistance type was simple. Therefore,it is important to identify new resistance genes and enhance resistance gene diversity. Meanwhile,pyramiding breeding of all-stage resistance gene and adult-plant resistance gene could be gradually developed,to achieve durable resistance of wheat cultivars(lines) against stripe rust in Sichuan Province. | Ren Yong Zhou Qiang Du Xiaoying He Yuanjiang Tao Ju Lei Jiarong Ou Junmei Zhou Fa Li Shengrong | 2016 | Plant Diseases and Pests2016，7，3： | 0 |
| 18 | Fine mapping and validation of a stable QTL for thousand-kernel weight in wheat(Triticum aestivum L.)显示文摘Thousand-kernel weight(TKW)is a measure of grain weight,a target of wheat breeding.The object of this study was to fine-map a stable quantitative trait loci(QTL)for TKW and identify its candidate gene in a recombinant inbred line(RIL)population derived from the cross of Kenong 9204(KN9204)and Jing411(J411).On a high-density genetic linkage map,24,26 and 25 QTL were associated with TKW,kernel length(KL),and kernel width(KW),respectively.A major and stable QTL,QTkw-2D,was mapped to an8.3 cM interval on chromosome arm 2DL.By saturation of polymorphic markers in its target region,QTkw-2D was confined to a 9.13 Mb physical interval using a secondary mapping population derived from a residually heterozygous line(F6:7).This interval was further narrowed to 2.52 Mb using QTkw-2D near-isogenic lines(NILs).NILs~(KN9204)had higher fresh and dry weights than NILsJ411at various grain-filling stages.The TKW and KW of NILs~(KN9204)were much higher than those of NILsJ411in field trials.By comparison of both DNA sequence and expression between KN9204 and J411,TraesCS2D02G460300.1(TraesKN2D01HG49350)was assigned as a candidate gene for QTkw-2D.This was confirmed by RNA sequencing(RNA-seq)of QTkw-2D NILs.These results provide the basis of map-based cloning of QTkw-2D,and DNA markers linked to the candidate gene may be used in marker-assisted selection. | Deyuan Meng Aamana Batool Yazhou Xuan Ruiqing Pan Na Zhang Wei Zhang Liya Zhi Xiaoli Ren Wenqing Li Jijie Li Yanxiao Niu Shuzhi Zheng Jun Ji Xiaoli Shi Lei Wang Hongqing Ling Chunhua Zhao Fa Cui Xigang Liu Junming Li Liqiang Song | 2023 | The Crop Journal2023，11，5： | 0 |
