| 2 | Expression,structure and function analysis of the sperm-oocyte fusion genes Juno and Izumo1 in sheep(Ovis aries)显示文摘Background:JUNO and IZUMO1 are the first receptor-ligand protein pairs discovered to be essential for spermoocyte fusion;their interaction is indispensable for fertilization.Methods:PCR was used to clone the full-length DNA sequence of the Juno gene in sheep.The single nucleotide polymorphism(SNP)loci of Juno were genotyped by Sequenom MassARRAY®.PCR combined with rapid amplification of cDNA Ends were used to clone the full-length cDNA sequence of Juno and Izumo1.Reverse transcriptase-PCR(RT-PCR)and real time-quantitative-PCR(RT-qPCR)were used to analyze the genes’expression in tissues of sheep,and single cell RNA-seq was used to analyze the genes’expression in oocytes,granulosa cells and follicular theca of polytocous and monotocous Small Tail Han ewes.Bioinformatics was used to analyze advanced structure and phylogeny of JUNO and IZUMO1 proteins.Results:The full-length DNA sequence of the Juno gene in sheep was cloned and nine SNPs were screened.We found a significant association between the g.848253 C>A locus of Juno and litter size of Small Tail Han sheep(P<0.05).The full-length cDNA sequence of Juno and Izumo1 genes from Small Tail Han sheep were obtained.We found a new segment of the Izumo1 CDS consisting of 35 bp,and we confirmed the Izumo1 gene has 9 exons,not 8.RT-qPCR showed that Juno and Izumo1 genes were highly expressed in ovarian and testicular tissues,respectively(P<0.01).Single cell RNA-seq showed Juno was specifically expressed in oocytes,but not in granulosa cells or follicular theca,while Izumo1 displayed little to no expression in all three cell types.There was no difference in expression of the Juno gene in oocyte and ovarian tissue in sheep with different litter sizes,indicating expression of Juno is not related to litter size traits.Bioinformatic analysis revealed the g.848253 C>A locus of Juno results in a nonconservative missense point mutation leading to a change from Phe to Leu at position 219 in the amino acid sequence.Conclusions:For the first time,this study systematically analyzed the expression,structure and function of Juno and Izumo1 genes and their encoded proteins in Small Tail Han sheep,providing the basis for future studies of the regulatory mechanisms of Juno and Izumo1 genes. | Wenping Hu Xinlong Dong Zhilong Tian Zhuangbiao Zhang Jishun Tang Benmeng Liang Qiuyue Liu Mingxing Chu | 2021 | Journal of Animal Science and Biotechnology2021，12，3： | 3 |
| 3 | Event vertex and time reconstruction in large-volume liquid scintillator detectors显示文摘Large-volume liquid scintillator detectors with ultra-low background levels have been widely used to study neutrino physics and search for dark matter.Event vertex and event time are not only useful for event selection but also essential for the reconstruction of event energy.In this study,four event vertex and event time reconstruction algorithms using charge and time information collected by photomultiplier tubes were analyzed comprehensively.The effects of photomultiplier tube properties were also investigated.The results indicate that the transit time spread is the main effect degrading the vertex reconstruction,while the effect of dark noise is limited.In addition,when the event is close to the detector boundary,the charge information provides better performance for vertex reconstruction than the time information. | Zi-Yuan Li Yu-Mei Zhang Guo-Fu Cao Zi-Yan Deng Gui-Hong Huang Wei-Dong Li Tao Lin Liang-Jian Wen Miao Yu Jia-Heng Zou Wu-Ming Luo Zheng-Yun You | 2021 | Nuclear Science and Techniques2021，32，5： | 3 |

| 7 | Physics potential of searching for 0νββ decays in JUNO显示文摘In the past few decades,numerous searches have been made for the neutrinoless double-beta decay(0νββ) process,aiming to establish whether neutrinos are their own antiparticles(Majorana neutrinos),but no 0νββdecay signal has yet been observed.A number of new experiments are proposed but they ultimately suffer from a common problem: the sensitivity may not increase indefinitely with the target mass.We have performed a detailed analysis of the physics potential by using the Jiangmen Underground Neutrino Observatory(JUNO) to improve the sensitivity to 0νββ up to a few me V,a major step forward with respect to the experiments currently being planned.JUNO is a 20 kton low-background liquid scintillator(LS) detector with 3%/(E(MeV))1/2 energy resolution,now under construction.It is feasible to build a balloon filled with enriched xenon gas(with^(136)Xe up to 80%) dissolved in LS,inserted into the central region of the JUNO LS.The energy resolution is ~1.9% at the Q-value of ^(136)Xe 0νββ decay.Ultra-low background is the key for 0νββ decay searches.Detailed studies of background rates from intrinsic 2νββ and 8~B solar neutrinos,natural radioactivity,and cosmogenic radionuclides(including light isotopes and ^(137)Xe) were performed and several muon veto schemes were developed.We find that JUNO has the potential to reach a sensitivity(at 90% C.L.) to T_(1/2)^(0νββ)of 1.8×10^(28)yr(5.6×10^(27)yr) with ~50 tons(5 tons) of fiducial136 Xe and 5 years exposure,while in the 50-ton case the corresponding sensitivity to the effective neutrino mass,mββ,could reach(5–12) meV,covering completely the allowed region of inverted neutrino mass ordering. | 赵洁 温良剑 王贻芳 曹俊 | 2017 | Chinese Physics C2017，41，5： | 1 |
| 8 | Improvement of machine learning-based vertex reconstruction for large liquid scintillator detectors with multiple types of PMTs显示文摘The precise vertex reconstruction for large liquid scintillator detectors is essential.A novel machine learning-based method was successfully developed to reconstruct an event vertex in JUNO.In this study,the performance of machine learning-based vertex reconstruction was further improved by optimizing the input images of neural networks.By separating the information of different types of PMTs and adding the information of the second hit of PMTs,the vertex resolution was improved by approximately 9.4% at 1 MeV and 9.8% at 11 MeV. | Zi-Yuan Li Zhen Qian Jie-Han He Wei He Cheng-Xin Wu Xun-Ye Cai Zheng-Yun You Yu-Mei Zhang Wu-Ming Luo | 2022 | Nuclear Science and Techniques2022，33，7： | 1 |

| 11 | Afterpulse measurement of JUNO 20‑inch PMTs显示文摘In this study,we present the large photomultiplier tube(PMT)afterpulse measurement results obtained from the Jiangmen underground neutrino observatory(JUNO)experiment.A total of 11 dynode-PMTs(R12860)from the Hamamatsu company(Hamamatsu Photonics K.K.(HPK))and 150 micro-channel plate PMTs(MCP-PMTs,GDB-6201)from the NNVT company(North Night Vision Technology Co.,Ltd.(NNVT))were tested.Subsequently,an afterpulse model was built according to the afterpulse time distribution and the probability of occurrence for these two types of PMTs.The average ratio of the total afterpulse charge with a delay between 0.5μs and 20μs to the primary pulse charge is∼5.7%(13.2%)for the tested MCPPMTs(dynode-PMTs).The JUNO experiment will deploy 20,01220-inch PMTs;this study will benefit detector simulation,event reconstruction,and data analysis regarding the JUNO experiment. | Rong Zhao Nikolay Anfimov Yu Chen Hang Hu Jun Hu Xiao‑Lu Ji Denis Korablev Min Li Alexander Olshevskiy Zhao‑Yuan Peng Arseny Rybnikov Zhong‑Hua Qin Jun Wang Wei Wang Zhi‑Min Wang Björn Wonsak | 2023 | Nuclear Science and Techniques2023，34，1： | 0 |
| 12 | Low-radioactivity ultrasonic hydrophone used in positioning system for Jiangmen Underground Neutrino Observatory显示文摘To satisfy the accurate positioning requirement of the calibration source in the Jiangmen Underground Neutrino Observatory, a Tonpilz-type hydrophone with low radioactivity and high electroacoustics is developed.The radioactivity of the proposed hydrophone is strictly controlled by selecting pure raw materials, especially active piezoelectric ceramics. The electroacoustic performance of the hydrophone is improved by making structural optimization. High sensitivity and aimed directivity are achieved using 33-mode piezoelectric ceramic rings arranged in series and improvement in the radiating head of the Tonpilz hydrophone, respectively. All electroacoustic performances are studied through finite element analyses.The simulations indicate that the electroacoustic performances of the hydrophones in linear alkylbenzene-based liquid scintillator can be approximately predicted according to the results in water because their differences caused by two types of acoustic media, water and liquid scintillator, are known. The tests show that the hydrophone prototype can achieve a maximum sensitivity of-209.3dB and a beamwidth of 132.2° at a frequency of 143 kHz.In addition, eight hydrophones only contributed to a background radioactivity level of 26 ± 4 mHz in the neutrino analysis. | Duo Teng Jiang-Lai Liu Guo-Lei Zhu Yue Meng Yuan-yuan Zhang Tao Zhang Kai Luo Rui Li Jia-Qi Hui | 2022 | Nuclear Science and Techniques2022，33，6： | 0 |
| 13 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 14 | Research on thermoforming process of JUNO large acrylic spherical panel显示文摘Introduction Jiangmen Underground Neutrino Observation(JUNO)focuses on determining neutrino mass hierarchy and other physical purposes.The central detector is one of the keys to the JUNO.The main structure of the central detector is an acrylic spherical container with a diameter of 35.4 m,which will be the largest acrylic spherical vessel in the world.Its construction will inevitably face many great challenges and difficulties.Method The thermoforming process of large acrylic spherical panel is introduced,which is a very important step in panel production.The effect of temperature on the curvature of panel during thermoforming is discussed.The thermal deformation of panel in thermoforming process is analyzed by finite element method.The bending experiment and curvature measurement are carried out,and the influence of deformation of the panel under gravity on the curvature of the panel is analyzed.Results The current thermoforming process makes the curvature of panel smaller than that of mold.The measurement results show that the curvatures are different due to the influence of gravity when the panel is placed on the mold or vertically.Some suggestions for improving the shape of spherical panels are put forward.In the thermoforming process,the temperature of the concave-convex surfaces of the panel should be controlled at the same level as far as possible.Another feasible method is to increase the radius of the forming mold to obtain a spherical panel with designed radius. | Xiao-Hui Qian Xiao-Yan Ma Yue-Kun Heng Jian-Xia Xiao Yue-Sheng Tang Gao-Feng Zhang Wei Cheng Xiao-Long Wang Wei He Ya-Tian Pei Xiao-Yu Yang Shao-Jing Hou | 2022 | Radiation Detection Technology and Methods2022，6，1： | 0 |
| 15 | Reconstruction of a muon bundle in the JUNO central detector显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)is a multi-purpose neutrino experiment.One of the main goals is to determine the neutrino mass ordering by precisely measuring the energy spectrum of reactor antineutrinos.For the detection of reactor antineutrinos,cosmogenic backgrounds,such as^(9)Li/^(8)He and fast neutrons induced by cosmic muons,should be rejected carefully by applying muon veto cuts,which require good muon track reconstruction.With a 20-kton liquid scintillator detector,the simulation shows the proportion of muon bundles(muon multiplicity≥2)to be approximately 8%in JUNO,whereas its reconstruction has been rarely discussed in previous experiments.This study proposes an efficient algorithm for muon track reconstruction based on the charge response of a photomultiplier tube array.This is the first reconstruction of muon bundles in a large-volume liquid scintillator detector.In addition,the algorithm shows good performance and potential for reconstruction for both a single muon and double muons(muon multiplicity=2).The spatial resolution of a single-muon reconstruction was20 cm,and the angular resolution was 0.5°.For doublemuon reconstruction,the spatial and angular resolutions could be 30 cm and 1.0°,respectively.Moreover,this paper also discusses muon classification and the veto strategy. | Cheng-Feng Yang Yong-Bo Huang Ji-Lei Xu Di-Ru Wu Yong-Peng Zhang Wu-Ming Luo Miao He Guo-Ming Chen Si-Yuan Zhang | 2022 | Nuclear Science and Techniques2022，33，5： | 0 |

| 20 | Study on acrylic transmittance for JUNO Central Detector显示文摘Background The Central Detector(CD)of the Jiangmen Underground Neutrino Observatory(JUNO)uses 20,000 tons of liquid scintillator as target mass,and the design value of energy resolution of neutrino is 3%at 1 meV.Acrylic transmittance is an important parameter for CD in order to maximize the detection of scintillating photons.Motivation The composition and processing techniques of acrylic can surely affect its transmittance.How the composition,thermoforming temperature,heat preservation time and surface treatment process of acrylic affect its transmittance was measured and analyzed.Methods According to these studies,JUNO determined its special acrylic composition and processing techniques:no components of plasticizer or anti-UV in the composition,decreasing the time span and temperature during the demolding of flat panel,and adopting suitable thermoforming temperature of spherical panel.Results Finally,the preproduction of spherical acrylic panels meets the JUNO requirement confirming a transmittance in ultrapure water greater than 96%at the wavelength of 420 nm. | Xiaoyu Yang Nan Li Yuekun Heng Xiaohui Qian Xiaoyan Ma Yuesheng Tang Jianxia Xiao Gaofeng Zhang Wei Cheng Hongbing Song Mengzhao Li Zhiyan Cai Kaixi Huang Zhi Wu Wei He Yatian Pei | 2021 | Radiation Detection Technology and Methods2021，5，2： | 0 |
