为研究飞机暖云焰剂催化后云系发生的物理响应,利用汕尾市双偏振雷达观测量及反演的云微物理特征参量,结合大气环境场探测数据,对2020年8月30日在广东省汕尾市北部区域实施的催化过程进行了分析,结果显示:这次过程是盛夏季节副高边缘的一次以暖云降水为主的对流性降水过程,天气尺度系统强迫较弱,大气层结不稳定,但水汽不充沛。在积云发展的暖云阶段引入吸湿性催化剂,16 min之后,暖云云系体积开始增加,差分反射率因子、差分相移率、雨水含量及降水强度的平均值都有明显增长,雨滴尺度增大、浓度明显增加,雨滴质量平均直径(D_(m))和表征雨滴数浓度的标准化参数(lgNW)增长幅度分别达到10.3%和39.5%,云系维持了大约1.5 h。吸湿性核先在催化层附近吸收水汽增长为数量众多的小云滴,与自然对流发展伴随的上升气流加强相互叠加,增强了云滴的碰并过程。众多小雨滴被上升气流带入0℃层之上使过冷雨滴短暂增多,促进了霰粒子的生成。

为了保持《民法典》的灵活性和开放性,“民事权利”章的部分条文没有列举权利客体,而是规定权利主体享有何种民事权利。这回避了权利客体研究中可能存在的理论分歧,增加了民法学者理解“民事权利”章的难度。为了充分理解已经被列举的权利客体,以及合理推导出未被列举的权利客体,权利客体的概念构造旨在阐释内涵清晰、逻辑统一的权利客体概念,形成类型多样、层次分明的权利客体体系;为了解决权利客体学说相互对立、分歧不断的问题,权利客体的认定构造旨在阐释方法合理、条理清晰的权利客体认定,在界定权利客体形态的同时,关注权利客体认定中的法律价值判断问题。

在各国民法典中,我国《民法典》首次设置了“民事权利”章。然而,我国民法学者分别从权利本位角度和条文设计角度对《民法典》“民事权利”章作出了完全相反的评价。持否定评价的学者对“民事权利”章所提出的质疑并不恰当,因为他们忽略了“民事权利”章在《民法典》贯彻权利本位中的重要作用。持肯定评价的学者对“民事权利”章的功能论述则存在论证不充分的问题,因为他们未能深入阐释“民事权利”章在条文设计层面所具有的独特功能。因此,为了恰当且充分评价《民法典》“民事权利”章,我国民法学者有必要从权利本位和条文设计双重视角对“民事权利”章作出新的理论阐释。

Recently,immune checkpoint inhibitors(ICIs)and poly(ADP-ribose)polymerase inhibitors(PARPi)have played a pivotal role in prolonging the recurrence-free survival of patients with ovarian cancer(OC).1,2 Although PARPi have revolutionized the treatment of OC,the absence of reliable predictive biomarkers limits the broad application of ICIs for patients with homologous recombination(HR)deficiency(HRD).3 CXC-chemokine ligand 13(CXCL13)is a cytokine constitutively secreted in the stromal cells of the B-cell region of secondary lymphoid tissue.4 It exclusively binds to the chemokine receptor CXCR5,which is abundantly expressed in subsets of mature circulating B lymphocytes,follicular helper T cells,and skin-derived dendritic cells,and governs the migration of these cells into secondary lymphoid organs in response to the CXCL13 gradient.5 In this study,we aimed to elucidate the role of CXCL13 in shaping the tumor immune microenvironment(TIME)in HR-deficient OC and to explore its relationship with the cGAS-STING signaling pathway.

Through combined applications of the transfer-matrix method and asymptotic expansion technique, we formulate a theory to predict the three-dimensional response of micropolar plates. No ad hoc assumptions regarding through-thickness assumptions of the field variables are made, and the governing equations are two-dimensional, with the displacements and microrotations of the mid-plane as the unknowns. Once the deformation of the mid-plane is solved, a three-dimensional micropolar elastic field within the plate is generated, which is exact up to the second order except in the boundary region close to the plate edge. As an illustrative example, the bending of a clamped infinitely long plate caused by a uniformly distributed transverse force is analyzed and discussed in detail.
