Differences in Wetland Efficiency Affect Future Lake Water Quality

Wetlands are often constructed to counteract eutrophication or brownification of downstream waters, although our understanding of their differences in efficiency and effects is still scarce. Therefore, we here used the upper and lower 95% confidence limits of the average retention capacity of 11 wetlands to represent efficient and inefficient wetlands, respectively. We then modelled future scenari

Rectangular Gilbert Tessellation

A random planar quadrangulation process is introduced as an approximation for certain cellular automata in terms of random growth of lines, called rays, from a given set of points. This model turns out to be a particular (rectangular) case of the well-known Gilbert tessellation, which originally models the growth of needle-shaped crystals from the initial random points with a Poisson distribution

Contrast-enhanced CT—Nephrotoxic or not? A critical review of propensity-score-adjusted studies

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

First global carbon dynamics from an observational and process-informed hybrid perspective : Oversimplified respiration representation likely drives divergence in terrestrial carbon sequestration across models

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

Drosha Dice(r)ing lipid metabolism in the liver

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.

Patients’ symptoms and challenges during the first year after allogeneic haematopoietic cell transplantation—patients’ own expressions

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

Thermal Photoemitter and Absorber

Marknaden för grönt stål: En utvärdering av OEM:ers affärscase och dekarboniseringsmålens roll som strategiska drivkrafter inom fordonssektorn

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

CD44v6 is associated with tumor aggressiveness and chemoresistance in bladder cancer

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

Museomics reveals genetic swamping over 200 years of a marginal native population of the northern forest tree Acer campestre by non-native genotypes introduced as ornamentals

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

Variation in diagnostic performance of fecal immunochemical test (FIT) by cutoffs used in screening programs globally

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

A necessary and sufficient condition for discrete-time consensus on star boundaries

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

Dielectric function, band-to-band transitions, and exciton properties of bulk single-crystal In2O3 from room temperature to 600 °C determined by in situ spectroscopic ellipsometry

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

Adverse health outcomes in violent crime convicted persons : risk factors for somatic inpatient healthcare utilization

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

Cyclicity and Iterated Logarithms in the Drury–Arveson Space

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∕

Probabilistic projections of global wind and solar power growth based on historical national experience

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
