Temporal Variation of Road Dust Load and Its Size Distribution—a Comparative Study of a Porous and a Dense Pavement

Resuspension of road dust contributes to air quality issues with resulting health impacts. Limited studies imply that porous pavements can initially mitigate PM10 emissions by acting as a dust trap, but the abrasion wear generates road dust and thus accelerates the clogging processes. In addition, knowledge regarding the impact of pavement types on road dust load dynamics is limited. Road traffic

Gaze-based attention network analysis in a virtual reality classroom

This article provides a step-by-step guideline for measuring and analyzing visual attention in 3D virtual reality (VR) environments based on eye-tracking data. We propose a solution to the challenges of obtaining relevant eye-tracking information in a dynamic 3D virtual environment and calculating interpretable indicators of learning and social behavior. With a method called "gaze-ray casting," we

Re-evaluating evidence for giant genomes in amoebae

Here we reassess available evidence for the long-held misconception of amoebae possessing exceptionally large genomes. Traditionally, estimates relied on inaccurate methods like DNA weight measurements, leading to inflated sizes. These methods failed to account for contaminating DNA from prey, endosymbionts, and intrinsic genomic features like ribosomal operon amplification. Modern sequencing tech

Parameter degeneracies associated with interpreting HST WFC3 transmission spectra of exoplanetary atmospheres

The Wide Field Camera 3 (WFC3) instrument on the Hubble Space Telescope has provided an abundance of exoplanet spectra over the years. These spectra have enabled analysis studies using atmospheric retrievals to constrain the properties of these objects. However, follow-up observations from the JWST have called into question some of the results from these older datasets, and highlighted the need to

Spiideo SoccerNet SynLoc : Single Frame World Coordinate Athlete Detection and Localization with Synthetic Data

Currently, most research and public datasets for video sports analytics are base on detecting players as bounding boxes in broadcast videos. Going from there to precise locations on the pitch is however hard. Modern solutions are making dedicated static cameras covering the entire pitch more readily accessible, and they are now used more and more even in lower tiers. To promote research that can t

Disentangling running coupling and conformal effects in QCD

We investigate the relation between a postulated skeleton expansion and the conformal limit of QCD. We begin by developing some consequences of an Abelian-like skeleton expansion, which allows one to disentangle running-coupling effects from the remaining skeleton coefficients. The latter are by construction renormalon free, and hence hopefully better behaved. We consider a simple ansatz for the e

"That fluidity out there" - Epiphanies and the Sea in Virginia Woolf's "To the Lighthouse"

Epiphanies constitute an essential aspect of Woolf's fiction, as well as her ideas about fiction. In "To the Lighthouse" they are part of the structure, but also part of the experience of life, how the flux of existence is perceived. This essay focuses not only on the ?little daily miracles? which replace a great revelation, but also on the nature of the chaos, the passing and flowin

MiR-335 regulates exocytotic proteins and affects glucose-stimulated insulin secretion through decreased Ca2+-dependent exocytosis in beta cells

Background and aims: Ca2+-induced exocytosis is essential for insulin to be secreted from beta-cells, and in islets from type-2 diabetic (T2D) donors the expression of several genes coding for exocytotic proteins is reduced. Largely this phenomenon cannot be explained by polymorphism; rather it is likely due to epigenetic factors like microRNAs (miRNAs). Indeed, previous studies have identified a

A sense of security : Spouses' experiences of participating in an orthopaedic case management intervention (the SICAM-trial)

The aim of the study was to explore and describe spouses' experiences of participating in a case management intervention during older patients' fast-track programme having total hip replacement as well as which intervention elements they found useful. Data were collected through qualitative interviews with 10 spouses from the intervention group of the SICAM-trial, directed by predetermined codes b

Bioenergy and Land Use Change-State of the Art

The dedicated production of biomass crops and the collection of residues in agriculture and forestry can lead to undesirable negative impacts and it is crucial that practices are found that ensure that these impacts are avoided or mitigated as far as possible. This chapter concerns the use of biomass for energy and the connection between increased bioenergy use and land use change (LUC). Land use

Cognitive and functional changes associated with Aβ pathology and the progression to mild cognitive impairment

Cognitively-normal people with evidence of β-amyloid (Aβ) pathology and subtle cognitive dysfunction are believed to be at high risk for progression to mild cognitive impairment due to Alzheimer's disease (AD). Clinical trials in later stages of AD typically include a coprimary endpoint to demonstrate efficacy on both cognitive and functional assessments. Recent trials focus on cognitively-normal

Polymorphisms in manganese transporters show developmental stage and sex specific associations with manganese concentrations in primary teeth

Background: Manganese (Mn) is an essential metal that can become neurotoxic at elevated levels with negative consequences on neurodevelopment. We have evaluated the influence of single nucleotide polymorphisms (SNPs) in Mn transporter genes SLC30A10 and SLC39A8 on Mn concentrations in dentine, a validated biomarker that reflects Mn tissue concentrations early in life. Methods: The study included 1

The Arabidopsis 14-3-3 family -target protein specificity and expression of isoforms

14-3-3 proteins comprise a family of highly conserved proteins. 14-3-3 proteins have been found in all organisms examined except for members of the prokaryotic kingdom. 14-3-3s are involved in numerous processes in the cell and they typically bind to phosphorylated motifs in other proteins and regulate their activities. In plants, 14-3-3 proteins are recognized as key regulators of primary metabo

Complex human-nature system interactions in a resource constrained world - system analysis of problems associated to resource use and scarcity, and potential solutions aiming at resource efficiency

This paper provides a systemic analysis of complex dynamic issues associated with resource use, scarcity and efficiency by applying systems thinking with respect to sustainability criteria. Casual loop diagramming methodology is adopted to create a conceptual model to better understand the interconnected patterns, cause effect relations and feedbacks between the three dynamic complex systems that

Characteristics and Outcomes of Patients Receiving a Second Rescue Valve During Transcatheter Aortic Valve Implantation

Background: Transcatheter aortic valve implantation (TAVI) has become a safe procedure. However, complications occur, including uncommon complications such as valve malposition, which requires the implantation of an additional rescue valve (rescue-AV). The aim was to study the occurrence and outcomes of rescue-AV in a nationwide registry. Methods: The Swedish national TAVI registry was used as the

Experimental Investigation of Glycerol Derivatives as Low-Concentration Additives for Diesel Fuel

The worldwide adoption of renewable energy mandates, together with the widespread utilization of biofuels has created a sharp increase in the production of biodiesel (fatty acid alkyl esters). As a consequence, the production of glycerol, the main by-product of the transesterification of fatty acids, has increased accordingly, which has led to an oversupply of that compound on the markets. Therefo

Exploring the impact of age on the predictive power of the National Early Warning score (NEWS) 2, and long-term prognosis among patients reviewed by a Rapid Response Team : A prospective, multi-centre study

Aim: To explore the impact of age on the discriminative ability of the National Early Warning Score (NEWS) 2 in prediction of unanticipated Intensive Care Unit (ICU) admission, in-hospital cardiac arrest (IHCA) and mortality within 24 hours of Rapid Response Team (RRT) review. Furthermore, to investigate 30- and 90-day mortality, and the discriminative ability of NEWS 2 in prediction of long-term

Age at onset as an index of genetic heterogeneity in major psychiatric and substance use disorders

Background Robust clinical indices of etiologic heterogeneity for psychiatric disorders are rare. We investigate whether age at onset (AAO) reflects genetic heterogeneity, utilizing Genetic Risk Ratios (GRR) derived from Family Genetic Risk Scores (FGRS). Methods We examined, in individuals born in Sweden 1940-2003, whether AAO for five primary disorders - drug use disorder (DUD), alcohol use diso
