BACKGROUND The association between tumor-infiltrating lymphocyte(TIL)levels and the res-ponse to neoadjuvant therapy(NAT)in patients with triple-negative breast cancer(TNBC)remains *** To investigate the predictive potential of TIL levels for the response to NAT in TNBC *** A systematic search of the National Center for Biotechnology Information PubMed database was performed to collect relevant published literature prior to August 31,*** correlation between TIL levels and the NAT pathologic com-plete response(pCR)in TNBC patients was assessed using a systematic review and *** analysis,sensitivity analysis,and publication bias analysis were also *** A total of 32 studies were included in this *** overall meta-ana-lysis results indicated that the pCR rate after NAT treatment in TNBC patients in the high TIL subgroup was significantly greater than that in patients in the low TIL subgroup(48.0%vs 27.7%)(risk ratio 2.01;95%confidence interval 1.77-2.29;P<0.001,I2=56%).Subgroup analysis revealed that the between-study hetero-geneity originated from differences in study design,TIL level cutoffs,and study *** bias could have existed in the included *** meta-analysis based on different NAT protocols revealed that all TNBC patients with high levels of TILs had a greater rate of pCR after NAT treatment in all protocols(all P≤0.01),and there was no significant between-protocol difference in the statistics among the different NAT protocols(P=0.29).Additionally,sensitivity analysis demonstrated that the overall results of the meta-analysis remained consistent when the included studies were individually *** TILs can serve as a predictor of the response to NAT treatment in TNBC *** patients with high levels of TILs exhibit a greater NAT pCR rate than those with low levels of TILs,and this predictive capability is con-sistent across different NAT regimens.

项目下乡中的经营行为引发了景观化建设现象,研究以湖北T村为例,从空间实践、生产机制和治理效应三方面对此展开分析。从景观化的空间实践来看,T村在项目试点中的密集投入和差异化建设,导致景观密集生产和村庄空间分化,并凸显了景观的工具价值。从景观化的生产机制来看,主要源于对项目的经营。在决策层面,省级政府以行政发包配合项目下发,容易导致资源堆砌和重复试点;在下发过程中,县乡政府缺少代理人,强化了项目的集中下发冲动;在执行层面,项目捆绑产生了较强的执行压力,导致目标对照基础上的空间营造。从景观化的治理效应来看,一方面有利于空间更新、基础设施改善和组织权威强化,另一方面又导致景观的后续养护难题、对生活景观的排斥、对村民生计的影响以及村民隔阂等。这种好坏参半的治理效应体现了“项目悬浮”问题,即项目与村民需求脱节。最后,研究还提出了基层社会从“经营项目”向“经营空间”的延伸。

在传统欧洲儿童文学中,“成长”呈现了儿童从天真到经验的动态发展历程,在这一过程中,儿童需要平衡的是个体内在独特价值和社会规约间的矛盾。然而,努力摆脱欧洲文化钳制、构建民族特色文化的美国,将反叛与沉思同样根植于儿童文学之中,儿童通常质疑成人世界的价值规范。21世纪的美国儿童文学进一步扩大了这一反叛精神,凸显儿童能动性与身份认同这两个重要成长主题。反乌托邦儿童文学构建起一个不受世俗标准制约的想象空间,儿童在这一空间中成为构建新世界的希望与力量。在一系列的变化中,儿童也开始重新认识多元文化语境下的自我身份的主体性,在接受自身独特属性的同时也实现了对民族身份的认同。

针对偏心航天器存在大轨控推力偏心以及轨控推力大小不可调节的问题,提出一种有限推力轨道与姿态控制方案.该轨道控制方案可以同时控制多个轨道要素.轨道控制中将控制量设计为推力角,解决轨控推力大小不可调节的问题.设计姿态控制方案对轨控所期望的推力角进行跟踪,并考虑轨控推力偏心形成的大干扰力矩.针对大干扰问题对传统的渐近稳定姿态控制律进行了改进,从而利用三轴姿态的耦合关系抵消干扰力矩的影响.通过数值仿真验证了轨道姿态控制方案的有效性.

采用2014~2022年中国30个省份面板数据,研究数据要素和数字载体、省际壁垒与地区发展差距之间的关系。研究发现,数据要素和数字载体均与地区发展差距呈现非线性关系,但是前者与地区发展差距呈现“U”型形态关系,后者则为倒“U”型形态关系。省际壁垒在数字经济对地区发展差距的影响中发挥着调节作用,省际劳动力流通壁垒会强化数据要素和数字载体对地区发展差距的作用力,表现为正向调节效应;而省际商品贸易壁垒则仅表现出对数据要素作用力的弱化,显示为负向调节效应。鉴于此,应加快推进后发地区数字载体建设及产业数字化转型,破除商品贸易壁垒,引导人才合理流动。

针对路面辨识方法需要大量训练集或高的算力支撑不利于驾乘感提升实现的问题,提出了一种改进的最小二乘估计方法,无需训练集,直接采集悬架响应来辨识路面激励及路面等级变化。在建立的路面等级系数和车速为变参数模型的基础上,探讨路面激励数据的取样处理规则,通过解耦行驶速度的影响,得到了实时的路面不平度系数。仿真结果表明,A-E级路面综合估值准确度在97%以上,对路面等级突变的响应时间少于0.15 s,对路面输入的跟随性能良好。采集不同路段不同车速下的实车动力学参数进行辨识,试验结果表明,该工况下估计值准确度为98.2%,与三米尺检测法所得实际路面等级相符,验证了这种车速解耦路面辨识方法的可行性及准确性。
