Skyfall: A Survival Analysis of the IMF Executive Board Members

open access: yesKyklos, Volume 79, Issue 1, Page 232-250, February 2026.
ABSTRACT In the absence of a retirement age constraint at the IMF, this study explores the tenure persistence within the Board of Directors of the International Monetary Fund (IMF) from 2009 to 2021, through a survival analysis. The findings highlight that extrinsic factors, namely sovereign crises, banking crises, the ratio of debt‐to‐GDP, and ...

Cazenave‐Dickstein‐Weissler‐Type Extension of Fujita'S Problem on Heisenberg Groups

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 499-511, 30 January 2026.
ABSTRACT This paper investigates the Fujita critical exponent for a heat equation with nonlinear memory posed on the Heisenberg groups. A sharp threshold is identified such that, for exponent values less than or equal to this critical value, no global solution exists, regardless of the choice of nonnegative initial data. Conversely, for exponent values

Large Language Models as Calibration Agents in Hydrological Modeling: Feasibility and Limitations

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Large language models (LLMs) represent the forefront of artificial intelligence, exhibiting substantial potential for advancing understanding and reasoning in complex Earth system sciences. Hydrological modeling, essential for water resource management and Earth system knowledge, predominantly relies on traditional calibration paradigms and ...

Soft and Strong: Elastic Conductors with Bio‐Inspired Self‐Protection

open access: yesAdvanced Materials, Volume 38, Issue 4, 16 January 2026.
A general reverse‐engineering approach is demonstrated for designing functional yarns that uses woven fabric architecture as a structural framework. The fabric‐based stretchable conductive yarns combine flexibility, high elasticity, low stiffness, self‐protection, and weavability with conventional textile processes. By fine‐tuning the number of elastic
