Tracing Three Decades of Low Earth Orbit Satellite Communication Development: A Bibliometric and Main Path Analysis of Network Architectures, Protocol Evolution, and Emerging Intelligent Services

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide‐area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in constellation deployment, routing mechanisms, resource management, and LEO–5G/6G ...

Students’ Experiences of Teachers’ Ways of Unpacking Visual Representations in the Context of Intermolecular Forces

open access: yesScience Education, EarlyView.
ABSTRACT This is the third article in a series, emanating from a project that used social semiotics and phenomenography to explore the role visual representations play in the teaching and learning of chemistry. Building on our earlier work that identified five qualitatively different ways that teachers may use to unpack visual representations in their ...

High‐Resolution Microlens‐Assisted Tunable n‐Type Optical Doping in Monolayer MoS2

open access: yesSmall, EarlyView.
The laser‐assisted microlens array processing (LAMP) technique enables sub‐diffraction, localized n‐type optical doping of monolayer MoS2 by utilizing self‐assembled microspheres as microlenses. Controlled sulfur vacancy formation under low‐power laser irradiation allows precise tuning of the carrier concentration.

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Radio Afterglow Detection and AI-driven Response (RADAR): A Federated Framework for Gravitational-wave Event Follow-up

open access: yesThe Astrophysical Journal Supplement Series
The landmark detection of both gravitational waves (GWs) and electromagnetic (EM) radiation from the binary neutron star merger GW170817 has spurred efforts to streamline the follow-up of GW alerts in current and future observing runs of ground-based GW ...
