Quantum Chromodynamics predicts a phase transition from hadronic matter to quark–gluon plasma (QGP) at high temperatures and energy densities, where quarks and gluons (partons) are no longer confined within hadrons. The QGP forms in ultrarelativistic heavy-ion collisions. Anisotropic flow coefficients, quantifying the azimuthal expansion of produced matter, probe QGP properties. Flow measurements
Atserias and Müller (JACM, 2020) proved that for every unsatisfiable CNF formula ℓ, the formula Ref(ℓ) stating that 'ℓ has small Resolution refutations"-does not have subexponential-size Resolution refutations. Conversely, when ℓ is satisfiable, Pudlák (TCS, 2003) showed how to construct a polynomial-size Resolution refutation of REF(ℓ) given a satisfying assignment of ℓ. A question that had remai
Climate debates often frame individual behaviour and systems change as distinct pathways to action. We suggest that social change arises from individuals’ agency within their roles in societal systems, and that this agency should be actively leveraged to achieve meaningful climate change mitigation.
Sensitive and frequent digital remote memory assessments via mobile devices hold the promise to facilitate the detection of cognitive impairment and decline. However, in order to be successful at scale, cognitive tests need to be applicable in unsupervised settings and confounding factors need to be understood. This study explored the feasibility of completely unsupervised digital cognitive assess
Background:Reports on sex differences in radiological characteristics of intracerebral hemorrhage (ICH) are few. Sex-related differences in hematoma location, volume, and imaging markers may contribute to variations in clinical presentation and outcome. We aimed to assess sex differences in non-contrast computed tomography (NCCT) features in an unselected ICH cohort.Methods:This observational stud
Debates about the future of wind and solar power are often framed around a false binary: either these technologies will continue accelerating or they are already losing momentum. Both views assume that renewables follow an S-curve with near-exponential expansion followed by slowdown. Using national deployment data, we show that renewables’ growth departs from ideal S-curves. Instead, it proceeds t
Background Prostate-specific membrane antigen (PSMA)-PET usage in patients with prostate cancer is growing rapidly. Thus, novel risk-group definitions based on PSMA-PET are urgently needed for guidelines, clinical use, and trial study design. We report improved risk classification based on PSMA-PET Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE; PPP) nomograms (PPP3) to prognos
Atopic dermatitis is associated with impaired health-related quality of life (HRQoL), especially in moderate-to-severe disease. The Dermatology Life Quality Index (DLQI) is the most widely used dermatology-specific measure, whereas the EuroQol Five-Dimension, Five-Level questionnaire (EQ-5D-5L), a generic preference-based instrument, assesses health status across diseases. This study examined the
The VOTS2025 is the third edition of the Visual Object Tracking Segmentation benchmark. Organised the VOT initiative, VOTS builds on 10 years of experience in organising VOT challenges. Building on the tracking setup introduced in VOTS2023, the challenge continues to integrate short-term and long-term tracking, as well as single-target and multi-target scenarios, using segmentation masks as the so
Background: Chronic subdural hematoma (CSDH) is among the most common neurosurgical conditions, yet management strategies vary worldwide despite an expanding evidence base. To harmonize clinical practice and facilitate the establishment of transnational recommendations, the 2024 joint iCORIC/DACSUHS symposium in Copenhagen included a Delphi process on the key aspects of CSDH management. Methods: A
Background: The objective of this study was to explore the potential of Airspace Dimension Assessment (AiDA) to rapidly determine the type and severity of airway obstruction, detect emphysema in individuals with chronic airflow limitation (CAL), and distinguish it from non-emphysematous obstruction, asthma, and absence of respiratory disease with normal spirometry. Methods: Among the 744 participa
Zinc-Manganese dioxide (MnO₂) batteries have garnered significant interest due to their high energy density, low cost and low toxicity. Crystalline MnO₂ has shown structural transformations during the intercalation and deintercalation of Zn, which influences the performance of the battery. Recent studies have demonstrated that amorphous MnO₂ shows better Zn storage capacity due to an increase in s
This study presents a coupled model incorporating a thermal propagation model and a fire model to investigate the fire safety of a large lithium-ion battery (Li-ion) module. The thermal propagation model employs a three-dimensional (3D) finite element method (FEM), while the fire model utilizes computational fluid dynamics (CFD). Literature data on material properties and thermal runaway character
Background: Mortality among critically ill COVID-19 patients has varied globally. In Sweden, geographic differences in mortality have also been observed. The current study aimed to determine whether mortality differences persist after adjusting for differences in case-mix, and to identify potential independent factors contributing to regional variations in mortality. Methods: We conducted a multic
Radial migration and dynamical heating redistribute stars within galactic discs and thereby modify the chemo-kinematic structure of their host galaxies. Usually, these secular processes are studied in N-body and hydrodynamical simulations of Milky Way analogues with stellar-dominated discs. In contrast, discs at high redshift are gas rich, which may qualitatively change how secular evolution proce
Many organisms reproduce through noncanonical modes such as parthenogenesis or hybridogenesis (clonal transmission of one parent’s chromosomes), but whether these arise abruptly or stepwise from each other remains unclear. We address this in the stick-insect genus Bacillus, which harbors several hybrid lineages with diverse reproductive modes. From haplotype-resolved phylogenies of >500 wild-caugh
Social behavior is observed in a wide range of species, and its potential benefits include protection from predators, enhanced feeding, and reproductive opportunities. Experimental approaches using artificial selection on sociability can answer fundamental questions about the evolution of social behavior, such as: Can sociability evolve by artificial selection? Is aggressiveness associated with so
Lower extremity arteries might be affected by atherosclerotic peripheral arterial disease (PAD), or by embolization causing ischaemic symptoms. Patients with PAD often have widespread atherosclerosis, and progression of PAD is associated with increased risk for both other cardiovascular events and cardiovascular mortality. Peripheral arterial disease patients should therefore be offered both non-p
The main demographic and psychological correlates of Well-Being (WB) are well-established, but have not yet been assessed in the Swedish population–regularly ranked among the world's top five ranked WB nations–based on large, nationally representative data. Using 2023 Global Flourishing Study data (N = 15,068), this paper analyzes Swedish WB across three domains: demography (e.g., gender, age, and
Background/aims: Acid–base status is important for understanding pathophysiology, making a diagnosis, planning effective treatment and monitoring progress of critically ill patients. Manual calculations are cumbersome, easily result in wrong conclusions. We wanted to develop an automated assessment of acid–base status. Methods: A simplified adaptive MATLAB script processing all available theory to
