Polycyclic aromatic hydrocarbons (PAHs) of molecular mass (MM) 302 Da comprise numerous structural isomers that are of high concern for human health. Because of their multiplicity, low abundance in the environment, and limited availability of authentic standards, their occurrence, composition, and environmental health risk remain not well characterized. Here we extend the characterization of MM 30
Ecological constraints and changing societal values require businesses to reconsider innovation opportunities. Sufficiency constitutes an emerging sustainability strategy for businesses that focuses on the absolute reduction of inputs and consumption levels to restrict resource use. This particularly challenges aspects of value generation, strategic orientation, and consumer focus in the context o
Formulating Research Problems addresses one of the most critical yet often overlooked aspects of research: how to define and frame the problem at the heart of a study. While most research methods texts devote only a few pages to this question, Johan Alvehus offers a dedicated, accessible, and practical guide that helps students move beyond vague topics toward the development of clear, rigorous, an
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
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
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
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
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
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
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
opulation ageing is increasing the demand for long-term care services across high-income countries, a trend which will continue as populations over 80 years old increase in size. Unpaid caregivers are often the main source of long-term care services for ageing, sick and disabled adults. Their time provides an important service to recipients while offsetting substantial costs to health care systems
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
Authors as laborers and capitalists. Political self publishing in 1970s Sweden.From the late 1960s and onwards, many Swedish authors started questioning the publishing industry. The relationship between author and publisher was increasingly interpreted as a relationship between wage-laborer and capitalist. As a consequence, initatives to help authors publish without a traditional publisher were la
