A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior

Polymer Composites, EarlyView.
Lichen residue, a renewable mineral‐organic material, was melt compounded with polylactic acid and triacetin in a twin‐screw extruder. ABSTRACT A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA).

A Simple Rheology‐Based Framework for Selecting Printing Parameters in Extrusion‐Based Hydrogel Additive Manufacturing

Polymer Engineering &Science, EarlyView.
An open analytical framework converts standard rheological measurements directly into the complete extrusion field and slicer‐ready printing parameters for Piston driven printers, enabling rapid operational window of printability in direct ink writing without CFD or machine learning. ABSTRACT Predicting whether a gel formulation will print successfully

Deformation, Creep, and Dynamics in Glassy Ionomers

Journal of Polymer Science, EarlyView.
Ionic architecture tunes the inelastic deformation of glassy ionomers. Simulations show that ionic associations leave the small‐strain elastic baseline nearly unchanged, but strongly reinforce yielding, strain hardening, and creep resistance. Polyampholyte architectures suppress nonaffine mobility and stress‐induced fluidization most effectively by ...

Recurving tropical cyclones in the western North Pacific are stronger than non‐recurving ones: Causes and implications

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the statistical characteristics of recurving tropical cyclones (TCs) over the western North Pacific (WNP). We find that recurving TCs are, on average, 38% stronger than non‐recurving TCs, owing to longer ocean exposure, fewer landfalls, and passage through warmer, more favorable thermal environments.

Adaptive Sliding‐Mode Control of a Perturbed Diffusion Process With Pointwise In‐Domain Actuation

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT A sliding mode–based adaptive control law is proposed for a class of diffusion processes featuring a spatially‐varying uncertain diffusivity and equipped with several point‐wise actuators located at the two boundaries of the spatial domain as well as in its interior.

Three‐Year Propagation Experiment at Ku‐, Ka‐, and Q‐Band in French West Indies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT From January 2021 to December 2023, the Office National d'Etudes et de Recherches Aérospatiales (ONERA) and the Centre National d'Etudes Spatiales (CNES) conducted a three‐year Earth‐space propagation measurement campaign in Guadeloupe. The experiment used beacon receivers deployed in Pointe‐à‐Pitre airport to record signals at 11.2, 19.7, and

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...
