Retrospective, propensity-score-adjusted (PSA) studies have indicated to practitioners in the field that contrast-induced acute kidney injury (AKI) after contrast-enhanced CT (CECT) is of minor importance or even non-existent. This has led to controversies between clinicians demanding CECT not to miss any diagnoses and radiologists reluctant or even refusing CECT in risky patients. A critical revi
Process-based biosphere models, which formulate biophysical ecosystem processes, provide a mechanistic framework for understanding terrestrial carbon dynamics. In contrast, data-driven approaches, e.g., upscaling eddy covariance (EC) fluxes using satellite observations and machine learning, offer empirical estimates. These complementary methods often diverge significantly, particularly in estimati
SREBP transcription factors are key regulators of lipid metabolism and play a central role in metabolic dysfunction-associated steatotic liver disease (MASLD). In a recent issue of Molecular Cell, Nie et al. 1 have discovered that Drosha, known for microRNA processing, regulates the maturation and activation of SREBP1 in the liver, and this seems to be important in MASLD.
Purpose: The study aimed to describe patients’ experiences of physical, psychological, social, and existential symptoms and challenges during the first year after allogeneic haematopoietic cell transplantation (allo-HCT). Methods: Quantitative and qualitative data were collected and analysed with descriptive methods as part of a large retrospective cross-sectional online survey of patients who und
Emission och absorption av termiskt ljus på fotonnivå Vi visar att emission och absorption av mikrovågsfotoner från en nanostruktur i millikelvinområdet når nära 100% effektivitet. Strukturen kan fungera som en termisk fotonkälla för kvantteknologin. De senaste åren har kvantteknologi vuxit fram som ett nytt spännande forskningsfält som det just nu satsas stora resurser på, både i Sverige och inThe development of controllable thermal photon sources is essential for the advancement of quantum computers, specifically for the development of sensitive detectors and the study of heat transport in superconducting circuits. This thesis investigates a device featuring a metallic copper island acting as a variable thermal bath, coupled to a superconducting microwave line through a clean interface
Stålindustrin står för ungefär 7-8% av världens växthusgasutsläpp, och fordonsindustrin är en av dess viktigaste kunder. Fordonstillverkare som Volvo, Mercedes och Scania möter idag hårdare krav på att minska utsläppen i sina försörjningskedjor, genom regelverk i EU som förändras snabbt och ett växande tryck att ansvara för sina koldioxidavtryck. I detta sammanhang har grönt stål blivit en strategThe steel sector accounts for approximately 7-8% of global greenhouse gas (GHG) emissions, and the automotive industry stands for a large part of its customer base. As Original Equipment Manufacturers (OEMs), such as Volvo, Mercedes and Scania etc., face tightening Scope 3 emission targets, evolving EU regulatory frameworks, and growing pressure to decarbonise their supply chains, the question of
Bidraget (bokkapitlet) ger en omfattande genomgång av AI, dess historiska utveckling, definitioner och rättsliga reglering, med särskilt fokus på EU:s AI-förordning. I bidraget beskrivs hur AI har utvecklats från teoretiska modeller på 1950-talet till en central del av befintlig digital infrastruktur, med tillämpningar inom både privat och offentlig sektor, inklusive produktion, sociala medier, di
Objectives: – To evaluate the prevalence of mood disorder symptoms and measure the quality of life in women with vulvar dermatoses attending a specialized vulvar clinic in southern Sweden. Materials and Methods: – A questionnaire-based study among consecutive women attending the vulvar unit at the Department of Dermatology and Venereology at Skåne University Hospital. Sociodemographic factors were
Bladder cancer is a fast-moving and recurrent malignancy where survival hinges on early detection and precise risk stratification. The search for robust biomarkers is urgent, and CD44v6 has emerged as a compelling candidate. In this study, we explored the clinical and functional associations of CD44v6 expression in bladder cancer. Integrated analyses of patient samples and cell lines showed that h
Using historical DNA (hDNA) from herbarium material, we reconstructed two centuries of population‐genetic change in the critically endangered Swedish field maple (Acer campestre). We genotyped 148 herbarium specimens collected from 1820 to 2020 with 12 nuclear microsatellite loci and plastid haplotypes, and compared them with contemporary Swedish and continental reference data. Expected heterozygo
Background: Quantitative fecal immunochemical test (FIT) is widely used for colorectal cancer (CRC) screening, with substantial variation in positivity thresholds across countries. This study examines how these thresholds affect FIT's diagnostic performance for detecting CRC and advanced precancerous lesions (APCL). Methods: We analyzed data from a single round screening of 7398 men and women aged
It is intuitive and well known, that if agents in a multi-agent system iteratively update their states in the Euclidean space as convex combinations of neighbors’ states, all states eventually converge to the same value (consensus), provided the interaction graph is sufficiently connected. However, this seems to be also true in practice if the convex combinations of states are mapped or radially p
We investigate the temperature-dependent complex dielectric function of bulk single-crystal In2O3 over the spectral range of 1–6 eV and temperatures from room temperature to 600 °C under high-vacuum conditions using in situ spectroscopic ellipsometry. The dielectric function was modeled using wavelength-by-wavelength and critical-point model dielectric function analyses. The dielectric function ex
Background: Violent Crime Convicted Persons (VCCPs) are at increased risk of somatic health problems over the life course. However, the topic remains insufficiently studied, particularly regarding interactions with healthcare services in high-risk groups over extended periods. This prospective study aimed to explore adverse somatic outcomes in young adult VCCPs with a history of imprisonment and t
Let Hd2 be the Drury–Arveson space, and let f∈Hd2 have bounded argument and no zeros in Bd. We show that f is cyclic in Hd2 if and only if logf belongs to the Pick-Smirnov class N+(Hd2). Furthermore, for non-vanishing functions f∈Hd2 with bounded argument and H∞-norm less than 1, cyclicity can also be tested via iterated logarithms. For example, we show that f is cyclic if and only if log(1+log(1∕
Despite the recent surge of wind and solar power, both technologies need to accelerate to meet climate goals. Yet, there are no robust methods to assess the likelihood of such acceleration. Here we show that renewable energy deployment follows a recurring pattern across countries with prolonged periods of relatively steady growth punctuated by growth pulses. Based on this insight and on observed g
This paper evaluates the multi-service operation of a heterogeneous second-life battery energy storage system (ESS) participating in the day-ahead electricity market and frequency containment reserves (FCR-N, FCR-D Up, FCR-D Down). A rolling horizon mixed integer linear programming (MILP) is developed to co-optimize market revenues, power schedule, and degradation, using linearized calendar and cy
This chapter examines elite polarisation as a challenge to governance in parliamentary democracies. We emphasise the distinction between ideological polarisation based on substantive policy disagreements from affective polarisation, characterised by identity-based animosity that creates barriers to cooperation even when policy compromise might otherwise be possible. While parliamentary regimes hav
The current rise in geopolitical tensions has heightened the need to understand the intricate relationship between sustainability and security, particularly in the context of the Global South. However, existing academic literature has paid limited attention to exploring this interconnection. This study aims to synthesize the existing knowledge on the nexus of sustainability and security in the Glo
