Properties, mechanisms, and perspectives of ultrafast laser modifications in silicate glass volume

open access: yesInternational Journal of Applied Glass Science, EarlyView.
Abstract Ultrafast laser irradiation of glass enables highly localized structural transformations within the material's bulk, unlocking diverse applications in photonics, data storage, and microfabrication. Here, we provide a concise yet comprehensive overview of the main types of femtosecond laser‐induced modifications in silica‐based glasses (Types I,

Market Potential, Road Accessibility, and Firm Births: Evidence From 20 Years of Road Investment

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT This paper investigates the causal effects of road accessibility, measured by market potential, on firm births in Portuguese municipalities between 1991 and 2016, a period marked by significant road improvements. We address the endogeneity of market potential by employing instrumental variables within Poisson Pseudo‐maximum Likelihood ...

Neural Evidence for Syntactic Unification in Second Language Sentence Comprehension: A Time‐Frequency Analysis

open access: yesLanguage Learning, EarlyView.
Abstract This study investigates whether syntactic unification occurs during online L2 sentence comprehension using time‐frequency analysis. We measured the oscillatory power changes in native English speakers and L1‐Cantonese L2‐English speakers while they were reading well‐formed English sentences, syntactically intact nonsense sentences, and random ...

End‐to‐end frequency enhancement framework for GPR images using domain‐adaptive generative adversarial networks

open access: yesComputer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Ground‐penetrating radar (GPR) offers nondestructive subsurface imaging but suffers from a trade‐off between frequency and penetration depth: High frequencies yield better resolution with limited depth, while low frequencies penetrate deeper with reduced detail.
