Difference between Half-mass Radius and Half-light Radius of Galaxies at 0.2 < z < 2.5 Revealed by JWST/NIRCam Data

open access: yesThe Astrophysical Journal
Using JWST observations in CANDELS fields, we measure the half-light radius ( r _e,light ) and half-mass–radius ( r _e,mass ) for 14,333 galaxies with stellar masses M _*  > 10 ^9 M _⊙ at redshifts 0.2  1, though a slight decreasing trend is seen between

The Age of Questions: Truth Regimes and Subjectivity in the Era of Large Language Models

open access: yesBehavioral Sciences &the Law, EarlyView.
ABSTRACT This essay explores how digital technologies shape subjectivity's infra‐political constitution, focusing on large language models (LLMs) like ChatGPT or Gemini within what philosophers, inspired by Michel Foucault, term the “digital truth regime.” After defining this regime, the essay identifies five key traits of LLMs: presentism in truth ...

Lenticular galaxy formation: possible luminosity dependence [PDF]

open access: yes, 2007
We investigate the correlation between the bulge effective radius (re ) and disk scale length (rd ) in the near-infrared K band for lenticular galaxies in the field and in clusters.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

On the Formation of Elliptical Galaxies

open access: yes, 1994
It is shown that the violent relaxation of dissipationless stellar systems leads to universal de Vaucouleurs profiles only outside 1.5 effective radii $R_e$. Inside $1.5 R_e$ the surface density profiles depend strongly on the initial conditions and are in general not in agreement with the de Vaucouleurs law.

Validation of a novel instrumented hoof boot with pressure sensors using force plate gait kinetics in horses at walk and trot

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Force plates (FP) are considered the gold standard for quantitative equine gait evaluation but are limited to experimental use. An instrumented hoof boot (IHB) with pressure sensors and an inertial measurement unit would allow clinicians to objectively assess kinetic parameters and gait symmetry.
