Notre Dame Journal of Formal Logic, 1997 In `On the cohomology of impossible figures' [Topologie Struct. 17, 11-16 (1991; Zbl 0743.52002)] \textit{R. Penrose} provides a mathematical analysis of certain geometrically impossible objects. Essentially, they are those whose parts cannot be consistently assembled, as is expressed by the failure of certain equations to have solutions.

Generalized Mechanism Model for Ecosystem Hysteresis
Advanced Science, EarlyView.A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...
