AP堆型核电站安全壳(CV)贯穿件插入板为核级厚板结构,其焊接质量直接决定第三道安全屏障的密封性与结构完整性。目前国内施工普遍采用焊条电弧焊,存在劳动强度大、质量一致性差、对高技能焊工依赖度高等问题,严重制约核电建造效率与质量稳定性。为解决上述工程痛点,研制了一套AP堆型CV贯穿件插入板专用自动化焊接装备。该装备以四轴联动焊接小车为核心执行机构,集成一体化涨紧定位机构、弧压自动跟踪系统及熔池远程监控系统,创新设计三档式离合器与180°可翻转监控相机,实现快速装夹、精准定位、全姿态稳定焊接与实时可视化监控。针对焊枪晃动问题,将原光轴铜套传动优化为直线导轨传动,使焊枪末端间隙控制在1 mm以内。采用SA-738Gr.B核级钢开展模拟件焊接验证,结果表明,装备运行平稳,焊枪末端晃动间隙≤1 mm,焊接效率较手工焊提升1倍以上。模拟件焊接验证表明,焊缝无损检测及理化性能均满足ASME标准,核心部件100%国产化,填补国内技术空白,为核电焊接提供高效可靠的自动化解决方案。 展开更多

OBJECTIVE:To investigate the clinical effect of abdominal moxibustion at the Zhongji(CV3)combined with Yiqi Tonglin Yangyin decoction(益气通淋养阴汤)and antibiotics on elderly women with complicated urinary tract infections.METHODS:One hundred and forty-four elderly female patients diagnosed with complicated urinary tract infections and admitted to our hospital were selected for this study.They were randomly assigned to two groups:the dual treatment group,consisting of 72 patients,treated with antibiotics combined with Yiqi Tonglin Yangyin decoction,and the triple treatment group,comprising 72 patients,who received abdominal moxibustion at the Zhongji(CV3)in addition to the dual treatment.The clinical efficacy,Traditional Chinese Medicine(TCM)syndrome score,immune function indicators,oxidative stress status indicators,symptom recovery,and recurrence were evaluated and compared.RESULTS:Before treatment,there was no statistically significant differences observed in the TCM syndrome score,levels of immunoglobulin A(IgA),immunoglobulin M(IgM),xanthine oxidoreductase(XOD),malondialdehyde(MDA)and superoxide dismutase(SOD)between the two groups(P>0.05).After treatment,the triple group exhibited a significantly higher overall response rate(95.9%>84.7%)compared to the dual group.Moreover,the triple group demonstrated elevated levels of IgA,IgM,and SOD,a lower TCM syndrome score,and reduced levels of XOD and MDA,along with a diminished recurrence rate.Additionally,patients in the triple group experienced a shorter time to return to normal symptoms,bacteriuria,and a routine urine output.CONCLUSION:Abdominal moxibustion at the Zhongji(CV3),combined with Yiqi Tonglin Yangyin decoction and antibiotics for treating complicated urinary tract infections in elderly women,can effectively improve the clinical symptoms,TCM syndromes,and immune function of patients.Additionally,it can reduce oxidative stress,promote patient recovery,and lower the recurrence rate with pronounced comprehensive efficacy. 展开更多

Durian(Durio zibethinus L.)is a tropical fruit of substantial nutritional and economic value from the family Malvaceae.Several genome assemblies for durian have been reported previously,but these assemblies contain gaps that have restricted their completeness and hindered their practical utility for downstream research.Here,we present the first gap-free genome assembly of Durio zibethinus cv.Chuongbo by integrating PacBio HiFi,Oxford Nanopore,and Hi-C sequencing data.The assembled genome is 824.78 Mb across 28 chromosomes,with a scaffold N50 of 30.88 Mb and 44,024 protein-coding genes.Comparative genomic analyses dated the divergence between D.zibethinus cv.Chuongbo and Herrania umbratica to 35 million years ago,and between two durian cultivars to 2 million years ago.D.zibethinus cv.Chuongbo exhibits substantial gene family expansion and a high abundance of species-specific genes,reflecting key genomic innovations underlying its unique biological traits.Additionally,comparative analysis of the TERT gene family across 27 Malvaceae species uncovered strong evolutionary constraints that maintain a predominant single-copy configuration,with two copies identified in several Gossypium taxa.This high-quality,gap-free genome provides a foundational resource for elucidating genome architecture,gene evolution,and the molecular basis of unique traits in durian and related Malvaceae species. 展开更多

Nocturnal starch remobilization is critical for plant carbon allocation and stress adaptation.Whileβ-amylase 3(BAM3)serves as the primary catalyst for starch degradation at night,its regulation mechanisms under stress remain to be fully characterized.The chloroplast vesiculation(CV)protein is crucial for maintaining chloroplast homeostasis during stress conditions,though its potential involvement in starch metabolic processes remains unexplored.Herein,we show that low night temperature(LNT)stress induces starch accumulation in tomato leaves,with SlCV overexpression exacerbating this phenotype and compromising LNT tolerance,whereas SlCV silencing promotes starch catabolism.RNA-seq and metabolome analyses detected lower levels of starch metabolites and amylase activity in SlCV overexpression plants.Strikingly,we have confirmed the physical interaction between SlCV and SlBAM3,and SlCV overexpression significantly accelerated the degradation of SlBAM3 under LNT stress,while SlCV knockout enhanced the stability of SlBAM3.Genetic validation confirmed that SlBAM3-silenced plants accumulate excessive starch and exhibit LNT-sensitive phenotypes,and SlBAM3 overexpression enhances cold tolerance.Furthermore,SlBAM3 complementation rescues the starch overaccumulation and LNT hypersensitivity of SlCV overexpression plants.These results elucidate the regulatory mechanism of starch metabolism mediated by SlCV and associated with SlBAM3 protein stability,providing novel insights into the starch metabolic pathway under cold stress. 展开更多

Objective:To investigate the distribution characteristics of sensory,sympathetic,and motor neurons as-sociated with the"Shenshu(BL 23)"and"Guanyuan(CV 4)"acupoints and the ovary,and to elucidate the neural anatomical connections between these acupoints and the ovary.Methods:In this study,dual fluorescent neural tracing was utilized,with twelve female Sprague-Dawley rats being randomly allocated into two groups(n=6 per group)for the purpose of administering tracer injections at distinct anatomical sites:the"BL 23"-ovary group received injections of Alexa Fluor 488-conjugated cholera toxin subunit B(AF488-CTB)at the left"BL 23"and Fluoro-Gold(FG)in the left ovary;the"CV 4"-ovary group received AF488-CTB at“CV 4”and FG in the left ovary.Three days post-injection,the distribution of AF488-CTB and FG-labeled neural components was observed in the dorsal root ganglia(DRGs),sympathetic chain,and spinal cord tissues.Results:①Sensory neurons labeled with AF488-CTB associated with"BL 23"were primarily distributed in the thoracic(T)10 to lumbar(L)2 DRGs,concentrated in T12-T13;postganglionic sympathetic neurons were mainly located in the thoracolumbar sympathetic chain;motor neurons were predominantly found in the anterior horn of the T11-L1 spinal cord segments.②Sensory neurons labeled with AF488-CTB associated with"CV 4"were primarily located in T10-L3 DRGs,concentrated in T13-L2 DRGs;postgan-glionic sympathetic neurons were mainly distributed in the lumbar sympathetic chain;motor neurons were primarily found in the anterior horn of T11-L2 spinal cord segments.③FG-labeled sensory neu-rons associated with the ovary were mainly distributed in the T9-L3 DRGs,concentrated in the T12-L2 DRGs;postganglionic sympathetic neurons were primarily located in the lumbar sympathetic chain.④Double-labeled(AF488-CTB and FG)sensory neurons associated with the"BL 23"and ovary were mainly distributed in the T12-T13 DRGs,with double-labeled postganglionic sympathetic neurons primarily in the lumbar sympathetic chain;double-labeled sensory neurons associated with the"CV 4"and ovary were mainly distributed in the T13-L1 DRGs,with double-labeled postganglionic sympathetic neurons primar-ily in the lumbar sympathetic chain.No double-labeled motor neurons were observed for either acupoint with the ovary.Conclusion:"BL 23"and"CV 4"and the ovary in rats exhibit segmental connections in sensory and sympathetic innervation,which may serve as the neural anatomical pathway and basis for acupuncture at these acupoints to regulate ovarian function. 展开更多

As the cornerstone of future information security,quantum key distribution(QKD)is evolving towards large-scale hybrid discrete-variable/continuous-variable(DV/CV)multi-domain quantum networks.Meanwhile,multicast-oriented multi-party key negotiation is attracting increasing attention in quantum networks.However,the efficient key provision for multicast services over hybrid DV/CV multi-domain quantum networks remains challenging,due to the limited probability of service success and the inefficient utilization of key resources.Targeting these challenges,this study proposes two key-resource-aware multicast-oriented key provision strategies,namely the link distance-resource balanced key provision strategy and the maximum shared link key provision strategy.The proposed strategies are applicable to hybrid DV/CV multi-domain quantum networks,which are typically implemented by GG02-based intra-domain connections and BB84-based inter-domain connections.Furthermore,the multicast-oriented key provision model is formulated,based on which two heuristic algorithms are designed,i.e.,the shared link distance-resource(SLDR)dependent and the maximum shared link distance-resource(MSLDR)dependent multicast-oriented key provision algorithms.Simulation results verify the applicability of the designed algorithms across different multi-domain quantum networks,and demonstrate their superiority over the benchmark algorithms in terms of the success probability of multicast service requests,the number of shared links,and the key resource utilization. 展开更多

NWA 16080 is a representative reduced CV carbonaceous chondrite(CVred),consisting mainly of chon-drules(47 vol%)and matrix(42 vol%),along with minor quantities of calcium-and aluminum-rich inclusions(CAI)and amoeboid olivine aggregates(AOA)(CAI+AOA,6 vol%)and opaque minerals(5 vol%).The chondrules exhibit well-preserved outlines and can be categorized into Type Ⅰ(Fa10).They primarily consist of magnesium-rich olivine,along with both low-Ca and high-Ca pyroxenes,and contain minor amounts of secondary plagioclase.Olivines present in chondrules display compositional zoning characterized whereas the matrix is composed of fine-grained olivine.Nickel-rich metal and nickel-poor sulfides are also present,along with trace amounts of magnetite.In contrast to standard oxidized CV chondrites(CVox),the presence of high metal,Ni-poor sulfides,and reduced magnetite in NWA 16080 indicates a more reduced parent-body environment.Shock metamorphism is classified as mild(S1),while terrestrial weathering is characterized as low(W2).Raman spectroscopy indicates a diverse spectrum of organic matter(OM)maturity:certain areas exhibit characteristics akin to other CVred chondrites,whereas others reach maturity levels comparable to those observed in CVox chondrites.The Raman parameters indicate that this meteorite is classified as approximately type 3.4 to 3.5.The overlapping OM maturity with certain CVox chondrites provides a contradiction to the anticipated depth-thermal layering outlined in the onion-shell model.This suggests that the CV parent body probably experienced more intricate processes,including impacts and fluid-rock interactions,rather than merely depth-dependent heating. 展开更多

Paraneoplastic neurological syndrome refers to certain malignant tumors that have affected the distant nervous system and caused corresponding dysfunction in the absence of tumor metastasis.Patients with this syndrome produce multiple antibodies,each targeting a different antigen and causing different symptoms and signs.The CV2/collapsin response mediator protein 5(CRMP5)antibody is a major antibody of this type.It damages the nervous system,which often manifests as limbic encephalitis,chorea,ocular manifestation,cerebellar ataxia,myelopathy,and peripheral neuropathy.Detecting CV2/CRMP5 antibody is crucial for the clinical diagnosis of paraneoplastic neurological syndrome,and anti-tumor and immunological therapies can help to alleviate symptoms and improve prognosis.However,because of the low incidence of this disease,few repo rts and no reviews have been published about it so far.This article intends to review the research on CV2/CRMP5antibody-associated paraneoplastic neurological syndrome and summarize its clinical features to help clinicians comprehensively understand the disease.Additionally,this review discusses the curre nt challenges that this disease poses,and the application prospects of new detection and diagnostic techniques in the field of paraneoplastic neurological syndrom e,including CV2/CRMP5-associated paraneoplastic neurological syndrome,in recent years. 展开更多
