Distinct Biotypes of Visual Perception in Major Depressive Disorder
Advanced Science, EarlyView.In a discover dataset (272 acute MDD patients), this work identifies a novel depression biotype characterized by impaired visual motion perception, using machine learning clustering. An independent dataset confirms the robustness of this biotype through cross‐validation and demonstrates its generalizability.

活动范围对青鳉鱼
Haiyang yu huzhao重尾分布现象广泛存在于自然界的各种生物运动模式之中，重尾分布现象会随环境的变化而变化。鱼类为适应生存环境，往往会选择更加高效的个体运动模式。以青鳉鱼(Oryzias latipes)为研究对象，在相同浅水条件(5 cm)下，控制其活动范围，探究青鳉鱼在不同水域面积(1.0 m×1.0 m、0.6 m×0.6 m、0.4 m×0.4 m、0.2 m×0.2 m以及0.1 m×0.1 m)条件下的运动模式。利用MATLAB软件将青鳉鱼的运动轨迹转换为具体数据，通过移动速度、移动加速度 ...
