Objective: The human cluster of differentiation(CD)300A, a type-I transmembrane protein with immunoreceptor tyrosine-based inhibitory motifs, was investigated as a potential immune checkpoint for human natural killer(NK) cells targeting hematologic malignancies(HMs).Methods: We implemented a stimulation system involving the CD300A ligand, phosphatidylserine(PS), exposed to the outer surface of malignant cells. Additionally, we utilized CD300A overexpression, a CD300A blocking system, and a xenotransplantation model to evaluate the impact of CD300A on NK cell efficacy against HMs in in vitro and in vivo settings. Furthermore, we explored the association between CD300A and HM progression in ***: Our findings indicated that PS hampers the function of NK cells. Increased CD300A expression inhibited HM lysis by NK cells. CD300A overexpression shortened the survival of HM-xenografted mice by impairing transplanted NK cells. Blocking PS–CD300A signals with antibodies significantly amplified the expression of lysis function-related proteins and effector cytokines in NK cells, thereby augmenting the ability to lyse HMs. Clinically, heightened CD300A expression correlated with shorter survival and an “exhausted” phenotype of intratumoral NK cells in patients with HMs or solid ***: These results propose CD300A as a potential target for invigorating NK cell-based treatments against HMs.

内部失效是激光增材制造镍基高温合金在高温下的典型疲劳失效模式，目前对这种失效模式的认知尚不充分。在650 °C下进行了不同应力比的轴向疲劳试验，随后采用扫描电镜、电子背散射衍射、聚焦离子束和透射电子显微镜等测试技术，研究了增材制造镍基高温合金的多尺度内部失效行为。结果表明，不论是否受缺陷影响，微裂纹主要从晶粒取向较软的大晶粒处萌生，然后沿最大剪切应力方向滑移和扩展，形成晶体学小平面，因此与晶粒特征相关的小平面开裂是一种典型的内部失效模式。对小平面裂纹附近的位错结构进行分析，在650 °C时，局部塑性变形是由反相边界剪切、沉淀物旁通以及堆积层错剪切机制的共同作用所引起的。结合裂纹尖端应力强度因子的定义，提出了与小平面裂纹特征相关的裂纹成核寿命预测方法，预测结果与实验结果具有较好的一致性。

当前对于证明标准的研究呈现一种结果视角下的预设思维,局限在认定案件事实的最后一步,包括寻求清晰注脚的“内涵之辨”与划分刻度阈值的“层次之辨”。实践中,对于证明标准的把握或“倚重证据锁链、识别证据缺口”,或“依托印证证明、探查证据矛盾”,或“聚焦控辩对抗、排除辩方质疑”,均未能深入以裁判者为能动主体的认知过程,导致其游离在主观属性的内核之外。溯因推理中的开放性论证与创造性启示,得以激活控辩双方就“假说”与“被观察到的事实”之因果关系分别承担证明责任,与“排除合理怀疑”的适用具有契合性。在不认罪案件中,对单个证据的查证属实、单一要件事实的推论以及全案证据的综合判断作出阶段性划分,依次进行疑点的锚定与疑点的排除,以此夯实证据基础与事实基础。在认罪认罚案件中,排除合理怀疑的证明标准仍应继续适用。由于事实认知模式、疑点锚定过程以及疑点排除方式等均发生了相应的转变,故不同路径之下的“排除合理怀疑”亦能呈现多元面相。
