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

Polymer 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,

The Effect of the Aging Process of Polyamide 11 Used in Flexible Pipelines and Its Influence on the Permeability of Carbon Dioxide

Polymer Engineering &Science, EarlyView.
Field degradation inducing changes in the Polyamide 11 permeability. ABSTRACT This study investigates how long‐term natural aging affects the CO2 permeability of polyamide 11 (PA11) pressure sheaths recovered from decommissioned flexible risers. PA11 samples were extracted from two 18‐year‐old risers—a gas‐lift line and an oil‐production line—and ...

Experimental Validation of Prediction Models of Pressure‐Throughput Behavior for Melt‐Conveying Elements in Fully Intermeshing Co‐Rotating Twin‐Screw Extruders

Polymer Engineering &Science, EarlyView.
Comparison between hybrid model prediction and experimental measurements of pressure‐throughput behavior of co‐rotating twin‐screw conveying elements shows the hybrid model performing well. ABSTRACT Modeling and simulation of the melt conveying of co‐rotating twin screw extruders, one of the important manufacturing machines in polymer processing, is ...

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

Journal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Building a genomic and herbarium biorepository for medicinal plants of the Western Ghats

PLANTS, PEOPLE, PLANET, EarlyView.
Medicinal plants support healthcare for millions of people and sustain livelihoods, yet many threatened species lack secure long‐term genetic protection. This study establishes a genomic and herbarium biorepository for medicinal plants of the Western Ghats, a global biodiversity hotspot facing intense human pressure.

Geometric Intuition Enables Resource‐Efficient Screening for β‐Barrel‐Like Folds in Viral Structural Dark Matter

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Predicted protein structures now enable fold discovery beyond the reach of sequence homology, but scalable and interpretable methods remain limited. We present Cooper‐Beta, a resource‐efficient, chain‐resolved framework for detecting β‐barrel‐like folds from strand connectivity.

In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action

Pest Management Science, EarlyView.
In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action. Cinmethylin inhibits FATs, disrupting eukaryotic de novo lipid biosynthesis and causing defects in cell division, elongation and integrity. We confirm FATs as the primary site of action in planta.

Pharmacokinetic and Pharmacodynamic Interactions Between Anti‐Asthma Drugs and Medicinal Plants: A Comprehensive Review

Phytotherapy Research, EarlyView.
ABSTRACT Asthma affects 260–300 million people worldwide. About 20%–35% of patients use medicinal plants with their asthma medication, often without telling their clinicians. Disclosure rates are low; up to 42% of asthma outpatients use herbal products, with no records in their charts.

Apigenin Protects Hypertensive Intracerebral Hemorrhage by Regulating Trx1 Through Binding to PRDX2

Phytotherapy Research, EarlyView.
ABSTRACT Intracerebral hemorrhage (ICH) remains the most severe stroke subtype with high mortality and disability rates. Although apigenin has shown cerebroprotective potential in preclinical studies, its mechanism of action, particularly in hypertensive ICH, remains poorly understood.
