Age of Information (AoI) is a widely used metric to quantify the freshness of updates in communication systems. Existing AoI analyses implicitly assume a shared or synchronized notion of time between transmitter and receiver, thereby neglecting distortions arising from relative motion and gravitational effects. In this paper, we investigate the impact of relativistic time dilation on information f
We provide a detailed characterization of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99;: 1.13; age: 7.4 Gyr; V mag: 8.25) hosts a transiting sub-Neptune, HD 85426 b, with an orbital period of 16.71 d and a blackbody equilibrium temperature of K. By jointly analysing HARPS-N RVs, TESS, and CHEOPS photometric data and using two different stellar activity mitigat
This paper examines how extreme weather events affect the mobility of low-income urban residents in Ghana. Bringing together scholarship on extreme weather and mobilities, it explores the differential impact of flooding on their everyday lives as they navigate the cities of Accra and Tamale. A range of qualitative methods were drawn on, including semi-structured interviews, focus group discussions
In recognition of outstanding articles published in the Journal of Comparative Physiology A, Editors’ and Readers’ Choice Awards are conferred annually to the top papers in the categories Original Research Paper and Review/Review-History Article. The recipients of the 2026 Editors’ Choice Awards were selected based on votes cast by the Editorial Board on articles published in 2025. In the category
We study a class of dynamical multi-commodity flows in transportation networks. These are modeled as dynamical systems describing the evolution of the densities of a number of different commodities across the cells of a transportation network. Each cell is characterized by commodity-specific increasing demand functions returning the maximum outflow of each commodity from the cell as a function of
Traumatic brain injury (TBI) is commonly associated with white matter injury, leading to persistent symptoms and long-term disability. While advanced age is linked to worse outcome post-TBI, the influence of sex remains highly controversial. The present study aimed to identify age- and sex-dependent differences in white matter pathology during the chronic phase of TBI using the central (midline) f
Quantification using the Centiloid (CL) scale has become a valuable information to consider when interpreting amyloid-PET images and is now implemented in several software packages. This work aims to assess the comparability of CL from [18F]flutemetamol scans derived using several research and commercial quantification pipelines. Methods: This analysis relies on three datasets: a test-retest cohor
Background: Knowledge is increasing about TSC-Associated Neuropsychiatric Disorders (TAND), but little is known about the potentially confounding effects of intellectual ability (IA) on the rates of TAND across age, sex, and genotype. We evaluated TAND in (a) children vs. adults, (b) males vs. females, and (c) TSC1 vs. TSC2 mutations, after stratification for levels of IA, in a large, internationa
Problempresentation: Vietnam drabbas av i genomsnitt 5-6 tyfoner varje år, och dessa kan orsaka stor förödelse och många dödsfall när de passerar in över land. När en tyfon passerar medför det högt vattenstånd, höga vågor, starka vindar och kraftiga regnfall. Om högt vattenstånd sammanfaller med höga vågor orsakar det översköljning samt erosion av strandvallar och sanddyner längs kustlinjen. Detta
We assessed hepatocellular carcinoma (HCC) risk associated with smoking and alcohol consumption and their interactions, using both questionnaire data and objective serum biomarkers. Information on smoking and alcohol consumption was collected at baseline from 450,112 participants of the EPIC cohort, among whom 255 developed HCC after a median follow-up of 14 years. In a nested case–control subset
BACKGROUND: Accurate risk stratification in older adults presenting to the emergency department (ED) is essential but challenging due to atypical presentations and age-related physiological changes. While vital signs are central to triage, their predictive value for short-term mortality in this population remains unclear. This study aimed to explore the association between initial vital signs and
The aim of this thesis is to make it simple and efficient to produce applications for smartphones. The main area of application is within the health care sector, where alarm receiving devices are needed to inform personnel of pending situations. Most medical alarm systems are unique and hence require a unique GUI (Graphical User Interface). However, at the core, the main functionality is to commun
The impact of climate on the annual cycle and interannual variability of CO2 fluxes is assessed in European evergreen needleleaf forests (ENFs) and deciduous broadleaf forests (DBFs) using observations from 19 sites, alongside outputs from process-based and data-driven models. All models capture the temporal phasing of CO2 fluxes, including a shorter sequestration period in northern rather than so
Background: Opioid use disorder is a chronic disorder with a high risk of overdose-related morbidity and mortality where a large proportion of these can be averted by timely administration of the antidote naloxone. For naloxone to be present when and where overdoses occur, broad-scale overdose education and naloxone distribution (OEND) must be established. A regional naloxone program was implement
A NNW-trending mafic dyke from the central-western Bastar craton yields a U[sbnd]Pb ID-TIMS baddeleyite age of 1944 ± 6 Ma. By correlating additional dykes with similar trend and geochemical characteristics, we identify a previously unrecognized dyke swarm, named herein the Pakhanjore swarm. Geochemical evidence suggests that the studied rocks are derived from partial melting of a spinel-rich, sha
BACKGROUND: Prior research has established a positive association between the single-measured triglyceride-glucose (TyG) index and hypertension. Nevertheless, longitudinal studies addressing the enduring impact of TyG index on incident hypertension are lacking. This study sought to explore the association between cumulative TyG index (cum-TyG) and incident hypertension, especially obesity-related
The radioactive noble gas radon (222Rn) is a suitable tracer for atmospheric transport and mixing processes that can be used to evaluate and calibrate atmospheric transport models or to estimate greenhouse gas (GHG) emissions using the so-called radon tracer method (RTM). However, these applications require reliable estimates of the 222Rn fluxes from the soil. This study evaluates two process-base
Atmospheric measurements of the short-lived radioactive noble gas radon-222 (222Rn) have many applications. Its concentrations are driven by atmospheric mixing as well as seasonal variations, which follow the seasonality of 222Rn exhalation from continental soils, with lower values during the wet winter and spring months compared to more dry summer conditions. Hence, it can be used as a tracer to
Here, we use carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), nitrous oxide (N2O) and radon (222Rn) data from the Saclay ICOS tall tower in France to estimate CO2, CH4 and CO fluxes within the station footprint from January 2017 to October 2024 and N2O fluxes from February 2019 to October 2024 using the Radon Tracer Method (RTM). We first performed a sensitivity study of this method appl
