A Machine Learning Framework for Flood Risk Assessment With Imbalanced Data

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT This study presents a machine‐learning framework for identifying areas of elevated flood risk using imbalanced, high‐dimensional geospatial datasets. Using the Mandra River Basin in Greece as a case study, an extreme gradient boosting (XGBoost) classifier was trained on 11 flood‐related features including hydrological, meteorological, soil and

Temporal Scaling of Hydrological Signals Reveals Forcing Persistence and Watershed Filtering Across the Contiguous U.S.

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Streamflow temporal persistence reflects both hydrological inputs and watershed filtering, but their relative contributions remain difficult to distinguish. We analyzed spectral scaling in precipitation, evapotranspiration, effective precipitation, streamflow, and the effective precipitation‐to‐streamflow transfer function across 671 ...

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

Journal of Applied Polymer Science, Volume 143, Issue 41, November 5, 2026.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Out‐of‐Plane Strain‐Decoupled Architecture for High‐Fill‐Factor Stretchable OLED Displays

Advanced Functional Materials, Volume 36, Issue 88, 2 November 2026.
A vertically decoupled multilayer SOLED architecture separates emissive pixel islands from deformable interconnects, allowing low‐modulus elastomeric layers to accommodate applied strain and suppress strain transfer to the OLED region. This design, combined with transparent hybrid encapsulation, enables a high fill factor (∼75%), stretchability ...
