When Ground Truth Has a Footprint: Rethinking Satellite Rainfall Validation
Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Accurate evaluation of satellite precipitation products has long depended on comparisons with rain gauge observations, which are often treated as ground truth. Yet this practice overlooks a basic mismatch of scale: gauges measure rainfall at a point, whereas satellite products estimate area‐averaged precipitation. In a recent study, Li et al. (

Shifty Frogs: Evidence of Iridescence Among Amphibians
Austral Ecology, Volume 51, Issue 7, July 2026.ABSTRACT Iridescence is a striking optical phenomenon observed in some animals whereby colour or reflectivity changes based on viewing angle, such that two observers in different locations may simultaneously perceive the same tissue differently. Among amphibians, there is limited photographic evidence of tissues displaying colour shifts that define ...

HUFFMAN CODING AS A NONLINEAR DYNAMICAL SYSTEM [PDF]
International Journal of Bifurcation and Chaos, 2011 In this paper, source coding or data compression is viewed as a measurement problem. Given a measurement device with fewer states than the observable of a stochastic source, how can one capture their essential information? We propose modeling stochastic sources as piecewise-linear discrete chaotic dynamical systems known as Generalized Luröth Series ...
