1039-TxPert：利用多重知识图谱预测转录组扰动效应
from 聊聊Sci
这项研究介绍了 TxPert，这是一种旨在预测基因扰动对转录组影响的深度学习框架。该模型通过整合 知识图谱（如 STRING 和 GO）与高通量筛选数据，能够有效模拟细胞在面对未见过的单基因或双基因扰动时的反应。TxPert 采用了潜空间转换技术，结合了基础状态编码器和基于 图神经网络 的扰动编码器，显著提升了跨细胞系的泛化能力。研究强调了使用 批次匹配对照 和检索指标进行严谨基准测试的重要性，证明了该模型在多项任务中优于现有方法。最终，这项技术有望通过 虚拟筛选 加速药物发现并深化对疾病机制的理解。References:Wenkel F, Tu W, Masschelein C, 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.
