Lexical Effects on Second Language Grammar Acquisition: Testing Psycholinguistic and Neurocognitive Predictions

open access: yesLanguage Learning, Volume 75, Issue 2, Page 424-457, June 2025.
Abstract Second language (L2) grammar learning is difficult. Two frameworks—the psycholinguistic lexical bottleneck hypothesis and the neurocognitive declarative/procedural model—predict that faster L2 lexical processing should facilitate L2 incidental grammar learning.

Well‐Posedness, Long‐Time Behavior, and Discretization of Some Models of Nonlinear Acoustics in Velocity–Enthalpy Formulation

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 8793-8805, 30 May 2025.
ABSTRACT We study a class of models for nonlinear acoustics, including the well‐known Westervelt and Kuznetsov equations, as well as a model of Rasmussen that can be seen as a thermodynamically consistent modification of the latter. Using linearization, energy estimates, and fixed‐point arguments, we establish the existence and uniqueness of solutions ...

General Decay and Blowing‐Up Solutions of a Nonlinear Wave Equation With Nonlocal in Time Damping and Infinite Memory

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 9046-9057, 30 May 2025.
ABSTRACT This paper shows that long‐term stability and blowing‐up solutions for a nonlinear wave equation with a nonlocal damping of Choi and MacCamy type and a nonlocal dispersion can occur. The method of proof of general decay relies on a suitable Lyapunov functional.
