Carbon and oxygen in metal-poor halo stars

open access: yes, 2019
Carbon and oxygen are key tracers of the Galactic chemical evolution; in particular, a reported upturn in [C/O] towards decreasing [O/H] in metal-poor halo stars could be a signature of nucleosynthesis by massive Population III stars. We reanalyse carbon,

Preliminary study for the measurement of the Lense-Thirring effect with the Galileo satellites [PDF]

open access: yes, 2013
The precession of the orbital node of a particle orbiting a rotating mass is known as Lense-Thirring effect (LTE) and is a manifestation of the general relativistic phenomenon of dragging of inertial frames or frame-dragging.

Non‐Syndromic Tumefactive Demyelinating Lesions in the Pediatric Population: Four Case Reports and Review of the Literature

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Introduction Tumefactive demyelinating lesions (TDLs) are large lesions (> 2 cm) seen in demyelinating syndromes such as multiple sclerosis, myelin oligodendrocyte glycoprotein antibody‐associated disorder, and neuromyelitis optica spectrum disorder. They rarely occur in children and most often have a monophasic course.

Auction-Based Coopetition between LTE Unlicensed and Wi-Fi

open access: yes, 2016
Motivated by the recent efforts in extending LTE to the unlicensed spectrum, we propose a novel spectrum sharing framework for the coopetition (i.e., cooperation and competition) between LTE and Wi-Fi in the unlicensed band.

A Systematic Mapping Review of Core Outcome Reporting in Surgical Research for Oesophageal Cancer

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Oesophageal carcinoma is a rising global health burden, with surgical resection and perioperative chemotherapy forming the cornerstone of curative treatment. However, uncertainty persists regarding the optimal surgical approach, partly due to heterogeneity in outcome reporting, which hinders data synthesis and evidence‐based decision‐making ...
