Firefighter exposures during structural fires : An overview of real-world data

This paper examines firefighter exposure to emissions during actual firefighting in building scenarios. The focus is on actual exposure, not small-scale lab tests, to identify research gaps in light of the International Agency for Research on Cancer (IARC) classification of firefighting as an occupation with a heightened risk for certain types of cancer. The work is based on a systematic literatur

Measurement of off-shell Higgs boson production in the H∗ → ZZ → 4ℓ decay channel using a neural simulation-based inference technique in 13 TeV pp collisions with the ATLAS detector

A measurement of off-shell Higgs boson production in the H∗ → ZZ → 4ℓ decay channel is presented. The measurement uses 140 fb−1 of proton–proton collisions at √s = 13 TeV collected by the ATLAS detector at the Large Hadron Collider and supersedes the previous result in this decay channel using the same dataset. The data analysis is performed using a neural simulation-based inference method, which

Search for Higgs boson decays into a Z boson and a light hadronically decaying resonance in pp collisions at s=13 TeV with the ATLAS detector

A search for decays of the Higgs boson into a Z boson and a light resonance, with a mass of 0.5–3.5 GeV, is performed using the full 140 fb−1 dataset of 13 TeV proton–proton collisions recorded by the ATLAS detector during LHC Run 2. Leptonic decays of the Z boson and hadronic decays of the light resonance are considered. The resonance can be interpreted as a J/ψ or ηc meson, an axion-like particl

Use of literary texts in science teaching : A scoping review

Previous research in various educational areas has shown that literary texts have much to contribute through offering perspectives, contexts, and ways of presenting content. The present study has a particular focus on science education. The purpose of science education is under debate, and research as well as large-scale frameworks such as PISA increasingly highlight student agency and action comp

Search for tt¯H/A→tt¯tt¯ production in proton–proton collisions at s=13 TeV with the ATLAS detector

A search is presented for a heavy scalar (H) or pseudo-scalar (A) predicted by the two-Higgs-doublet models, where the H/A is produced in association with a top-quark pair (tt¯H/A), and with the H/A decaying into a tt¯ pair. The full LHC Run 2 proton–proton collision data collected by the ATLAS experiment is used, corresponding to an integrated luminosity of 139fb-1. Events are selected requiring

Common femtoscopic hadron-emission source in pp collisions at the LHC

The femtoscopic study of pairs of identical pions is particularly suited to investigate the effective source function of particle emission, due to the resulting Bose–Einstein correlation signal. In small collision systems at the LHC, pp in particular, the majority of the pions are produced in resonance decays, which significantly affect the profile and size of the source. In this work, we explicit

Differential cross-section measurements of Higgs boson production in the H → τ+τ− decay channel in pp collisions at s = 13 TeV with the ATLAS detector

Differential measurements of Higgs boson production in the τ-lepton-pair decay channel are presented in the gluon fusion, vector-boson fusion (VBF), VH and tt¯H associated production modes, with particular focus on the VBF production mode. The data used to perform the measurements correspond to 140 fb−1 of proton-proton collisions collected by the ATLAS experiment at the LHC. Two methods are used

Northvolt: The Broken Promise?

Within months, everything changed in the autumn of 2024. Northvolt, once the defining symbol of Sweden’s green transition, suddenly found itself at the centre of one of the country’s most serious economic crises in decades. What had been a modern, sustainable fairytale of rapid growth and global ambition turned into a question of survival, ownership, and maintaining the Northvolt name. It is now

Improved characterization of the TOI-2141 system: A dense sub-Neptune with non-transiting inner and outer companions

Aims. We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star on a relatively long orbit of 18.26 days, by combining new photometric and spectroscopic observations. Methods. We analyzed new space-based photometry from TESS and CHEOPS, as well as 61 radial velocity measurements from HARPS-N. We performed individu

Religion and Indigenous Worldviews in Climate Change Adaptation – A Scoping Review

This thesis presents a scoping review of academic literature on the intersection of religion, spirituality, and Indigenous worldviews with climate change adaptation. While adaptation research has traditionally emphasised technical, institutional, and financial dimensions, the cultural and spiritual dimensions shaping community responses remain underexplored. To address this gap, the review systema

Multiplicity-dependent jet modification from di-hadron correlations in pp collisions at √s = 13 TeV

Short-range correlations between charged particles are studied via two-particle angular correlations in pp collisions at √s = 13 TeV. The correlation functions are measured as a function of the relative azimuthal angle ∆φ and the pseudorapidity separation ∆η for pairs of primary charged particles within the pseudorapidity interval |η| < 0.9 and the transverse-momentum range 1 < pT< 8 GeV/c. Near-s

Light neutral-meson production in pp collisions at √s = 13 TeV

The momentum-differential invariant cross sections of π0 and η mesons are reported for pp collisions at = 13 TeV at midrapidity (|y| < 0.8). The measurement is performed in a broad transverse-momentum range of 0.2 < pT< 200 GeV/c and 0.4 < pT< 60 GeV/c for the π0 and η, respectively, extending the pT coverage of previous measurements. Transverse-mass-scaling violation of up to 60% at low transvers

Quality of Life and Economic Burden in Swedish Adults with Atopic Dermatitis : A Cross-sectional Survey of Patientreported Outcomes

Atopic dermatitis (AD) is a chronic skin disease associated with impaired quality of life. Evidence from Sweden on out-of-pocket expenses and productivity losses remains limited. This study assessed the burden of AD among adults in relation to health-related quality of life (HRQoL), work productivity, activity impairment, willingness to pay for symptom relief, economic outcomes, considering comorb

Advancement flaps in perianal fistulizing Crohn’s disease: technical steps and current evidence

Fistulizing perianal Crohn’s disease is complex and negatively affects quality of life. Rectal advancement flap (AF) has been widely adopted as a sphincter-preserving procedure for treating complex anal fistulas. The European Crohn’s and Colitis Organisation (ECCO) guidelines on surgical treatment of Crohn’s disease state that AF is a therapeutic option for patients with Crohn’s disease and comple

Time-resolved NIR/Vis spectroscopy for analysis of solids: Pharmaceutical tablets

Time-resolved spectroscopy in the visible and near-infrared (NIR) regions was used in a feasibility study for analysis of solid pharmaceuticals. The objective of the experiments was to study the interaction of light with pharmaceutical solids and to investigate the usefulness of the method as an analytical toot for spectroscopic analysis. In these experiments, a pulsed Ti:sapphire laser and white

Using an abstract geometry in virtual reality to explore choice behaviour: visual flicker preferences in honeybees

Closed-loop paradigms provide an effective approach to studying visual choice behaviour and attention in small animals. Different flying and walking paradigms have been developed to investigate behavioural and neuronal responses to competing stimuli in insects such as bees and flies. However, the variety of stimulus choices that can be presented over one experiment is often limited. Current choice

Glycoprotein 340 and sialic acid in minor-gland and whole saliva of children, adolescents, and adults.

Glycoprotein 340 (gp-340) is a bacterial-binding glycoprotein found in major-gland and minor-gland saliva. Sialic acid, a common terminal structure of salivary glycoproteins, interacts with microorganisms and host ligands, as well as with free radicals. This study investigated the contents of gp-340 and sialic acid in minor-gland saliva and whole saliva of children (3 yr of age), adolescents (14 y
