1158-定量组织分析中的细胞邻近偏好方法比较与优化
from 聊聊Sci
这份研究系统地评估并优化了空间组学中的细胞邻近偏好（NEP）分析方法。研究团队通过对比histoCAT、Squidpy和Giotto等多种现有工具，揭示了各方法在区分组织架构特征以及捕捉细胞间双向相互作用方面的优劣。作者指出，许多传统算法因采用分类评分而难以识别细微的组织差异，且在处理细胞丰度偏差时存在局限。为此，研究提出了一种名为COZI（条件Z分数）的新型分析框架，能够更灵敏、准确地量化细胞间的定向吸引或排斥关系。通过对三阴性乳腺癌和心肌梗死等生物数据集的验证，该研究为定量组织微环境分析提供了重要的选择指南与技术改进方案。References:Schiller C, Ibarra-Arellano M A, Bestak K, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
