Experimental and Numerical Assessment of Progressive Damage in CF/PEEK Laminates Under Monotonic and Progressive Cyclic Four‐Point Bending

open access: yesPolymer Composites, EarlyView.
Experimental four‐point bending of CF/PEEK laminates under monotonic and progressive cyclic loading is assessed using classical lamination theory and a calibrated Hashin progressive damage model. ABSTRACT Carbon‐fiber‐reinforced PEEK composites combine high specific strength, corrosion resistance, and damage tolerance, supporting their use in aerospace,

CSRcalculator: A reproducible framework for understanding plant ecological strategies

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants respond to environmental change is essential for conserving biodiversity and managing ecosystems under climate change. We developed CSRcalculator, an open‐source platform that brings together major competitor, stress‐tolerator, ruderal (CSR) models to make ecological strategy classification accessible, reproducible and scalable.

Supervised Protein Structure Classification Using Topological Persistence With DeltaFold

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Recent advances in protein structure prediction have considerably increased the number of available structures, underscoring the need for scalable and accurate methods to compare and classify this huge amount of data. Current approaches based on sequence alignment or structural superposition often lack sensitivity and/or are computationally ...

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

open access: yesPackaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

New views of some invariants associated with the Cartesian 2D velocity gradient tensor

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Vorticity and divergence of horizontal flow are fundamental quantities in meteorology; both are linear functions of the four elements of the 2D velocity gradient tensor and both are formally unchanged under coordinate rotation. We explore four quadratic functions of the elements that are geometrically invariant in this sense, finding some novel ...
