Pediatric Obesity, Volume 20, Issue 12, December 2025.ABSTRACT Background A dual‐energy x‐ray absorptiometry (DXA)‐derived phenotype classification based on fat mass and muscle mass has been developed for adults. We extended this to a paediatric population. Methods Children's (≤ 17 years) DXA data in NHANES (n = 6120) were used to generate sex‐ and age‐specific deciles of appendicular skeletal muscle mass

A spatially and temporally localized sub-laser-cycle electron source [PDF]
, 2006 We present an experimental and numerical study of electron emission from a sharp tungsten tip triggered by sub-8 femtosecond low power laser pulses. This process is non-linear in the laser electric field, and the non-linearity can be tuned via the DC ...

Veterinary Clinical Pathology, Volume 54, Issue 4, Page 355-361, December 2025.ABSTRACT Backgrounds Studies investigating the influence of sampling methods on point‐of‐care viscoelastic test (VCM Vet) results are limited. Objectives Investigating the impact of blood sampling methods on VCM Vet results in dogs, and determining if results are affected by hematological parameters, and blood sampling difficulty.

Art et archives: une perspective archivistique
Encontros Bibli, 2009 Bien que les artistes contemporains aient été nombreux depuis la fin des années 1980 à utiliser des documents d’archives dans leurs travaux, le phénomène a été peu étudié jusqu’ici par les archivistes.

The environmental footprint of academic and student mobility in a large research-oriented university
Environmental Research Letters, 2019 Academic mobility for field work, research dissemination and global outreach is increasingly recognized as an important contributor to the overall environmental footprint of research institutions. Student mobility, while less studied, also contributes to

Comb-calibrated solar spectroscopy through a multiplexed single-mode fiber channel [PDF]
, 2015 We investigate a new scheme for astronomical spectrograph calibration using the laser frequency comb at the Solar Vacuum Tower Telescope on Tenerife. Our concept is based upon a single-mode fiber channel, that simultaneously feeds the spectrograph with ...

Winter Methane Fluxes Over Boreal and Arctic Environments
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract Unprecedented warming of Arctic–boreal regions (ABR) has poorly understood consequences on carbon cycle processes. Limited winter data add uncertainty to annual methane (CH4) budgets. In this study, winter CH4 flux measurements were conducted using the snowpack diffusion gradient method over five ABR ecosystem types in Canada and Finland ...

New Fermions at e$^+$e$^-$ Colliders: II.~Signals and Backgrounds
, 1993 We discuss the production, at high--energy e$^+$e$^-$ linear colliders, of new heavy fermions predicted by extensions of the Standard Model. We analyze in great details the various signals and the corresponding backgrounds for both pair production and ...

Phase metrology with multi-cycle two-colour pulses [PDF]
, 2016 Strong-field phenomena driven by an intense infrared (IR) laser depend on during what part of the field cycle they are initiated. By changing the sub-cycle character of the laser electric field it is possible to control such phenomena.
