754-ovrlpy：识别空间转录组学中的三维信号重叠
from 聊聊Sci
这项研究介绍了一种名为 ovrlpy 的新型计算工具，旨在解决空间转录组学（SRT）数据中常被忽略的垂直维度重叠问题。由于传统分析通常将 3D 组织切片投影为 2D 平面，这会导致来自不同深度的细胞信号混淆，产生空间双细胞伪影。ovrlpy 通过将组织虚拟划分为顶层和底层，并计算垂直信号完整性（VSI），能够有效识别细胞重叠、组织折叠及分割错误。该算法采用无监督学习模式，不依赖预设的细胞形状，适用于多种组织类型和成像平台。通过滤除低 VSI 的重叠信号，研究者可以显著提高细胞分型的准确性和空间分析的信噪比。这项工具为空间组学数据提供了必要的质量控制手段，确保了高分辨率组织结构解析的可靠性。References: Tiesmeyer S, Müller-Bötticher N, Malt A, 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.
