Shifts in dissolved organic matter (DOM) composition, caused by seasonal or episodic events, can significantly alter the removal of per- and polyfluoroalkyl substances (PFAS) by granular activated carbon (GAC). To investigate how changes in feedwater composition impact PFAS removal in aged GAC, a 20-day experiment was conducted in eight parallel small-scale columns. Columns were filled with aged G
Aim: A prolonged time from diagnosis to start of radiotherapy (TTRT) for malignant disease may negatively influence survival, but studies in squamous cell carcinoma of the anus (SCCA) are largely lacking. The purpose of this study was to investigate the impact of TTRT on overall survival (OS) and anal cancer-specific survival (ACSS) in a nationwide population-based cohort from the Swedish Anal Can
BACKGROUND: Many studies have shown that coffee and tea consumption is associated with diabetes. However, limited research exists on their effects on the risk of macrovascular complications in diabetic patients. Therefore, the purpose of this study was to examine the relationship between the intake of coffee and tea and macrovascular complications in patients with type 2 diabetes mellitus (T2DM).M
A brain-computer interface (BCI) controls a device using brain signals rather than conventional input modalities such as a computer mouse. Before use, the BCI must be calibrated. During the calibration process, the user repeatedly performs mental tasks while electroencephalography (EEG) data is collected. The calibration process is often time-consuming and tiresome for the user. One approach to re
SaKu-projektet har varit ett tvåårigt, Forte-finansierat projekt som pågick mellan åren 2024 och 2026 och som har undersökt och vidareutvecklat samverkan mellan socialtjänsten i Lunds kommun och Socialhögskolan vid Lunds universitet, med särskilt fokus på hur kunskap kan cirkulera mellan praktik och akademi. Genom att kartlägga befintliga samverkansformer och pröva nya möjligheter till fördjupad s
Automated storage systems and large-scale freezers can be challenging for conventional fire protection systems. Instead, an oxygen reduction system (ORS) could be a suitable option. In an ORS the design oxygen concentration is the key parameter for the level of protection achieved by the system. However, current methods for determining this concentration yield varying results and either require la
This work considers infinite-horizon optimal control of positive linear systems applied to the case of network routing problems. We demonstrate the equivalence between Stochastic Shortest Path (SSP) problems and optimal control of a certain class of linear systems. This is used to construct a heuristic search framework for linear positive systems inspired by existing methods for SSP. We propose a
Cancer progression is driven by early dysregulation of the immune system and tumor-intrinsic mechanisms. Hypoxia, lactate accumulation and IL-6 signaling induce highly overlapping tumor-promoting effects, including angiogenesis, epithelial–mesenchymal transition, metastasis, immune evasion and treatment resistance, suggesting that these pathways interact and amplify one another. This parallel acti
STUDY QUESTION: Do donor-conceived adolescents in lesbian- and heterosexual-couple families intend to request information about their identity-release oocyte or sperm donor? SUMMARY ANSWER: While more than half of adolescents intended to request donor information, being uncertain about making such requests was quite common, particularly among adolescents reporting better family functioning and tho
Prenatal air pollution exposure has been associated with impaired fetal growth. However, the underlying biological mechanisms, potentially involving the placenta, remain poorly understood. This study aimed to investigate the effects of maternal air pollution exposure on placental biomarkers of oxidative stress and cellular ageing, and to determine whether these biomarkers contribute to the associa
Health is widely recognized as shaped by social and structural conditions, yet time remains largely absent from dominant public health frameworks. This paper brings together sociological and epidemiological perspectives to argue that time is a fundamental dimension of health that has been insufficiently articulated. Rather than proposing a new determinant, it reframes time as an essential conditio
Interstitial lung diseases (ILDs) comprise a heterogeneous group of diffuse parenchymal lung disorders associated with progressive fibrosis, impaired gas exchange, and substantial morbidity. In recent years, the coexistence of obstructive sleep apnea (OSA) in ILD has emerged as an underrecognized yet clinically meaningful overlap. Evidence indicates that OSA is highly prevalent in ILD—even among n
Jaynes–Cummings Hamiltonian provides the elemental description of a two-level system interacting with a photonic mode. In this work, we review the Jaynes–Cummings formalism for an electronic two-level system. The purpose is to summarize and connect together the key theory concepts relevant for the transmission response probed typically in the experiments. The review provides a photonic mode descri
Lead-halide perovskites are a promising material platform as semiconductors in next-generation solar cells because of their solution processability, defect tolerance, and tunable optoelectronic properties. Mixed iodide–bromide perovskite compositions are attractive as wide-bandgap absorbers but suffer from significant operational instabilities. Incorporation of chloride to form triple-halide perov
Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes classified into the auxiliary activity (AA) families of the CAZy database. They oxidatively cleave glycosidic bonds in recalcitrant polysaccharides, playing a key role in biomass degradation and contributing to the virulence of some pathogens. The redox state of the active-site copper and its coordination geometry are central
Objectives: To evaluate quality of life, patient-reported outcomes, and survivorship after different nodal staging strategies in endometrial cancer, with a focus on lower-extremity lymphedema after sentinel lymph node mapping versus lymphadenectomy. Methods: A systematic literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. M
Construction sites remain a sparse source of digital information, even though up-to-date knowledge of site conditions underpin planning, progress control, and safety. This paper contributes a field-grounded roadmap toward frequent robotic digitalization of construction sites. It shifts attention from robotic capture capability to the capture-to-consumption chain required for operational use and tr
Integrating wastewater treatment with energy recovery and aquifer recharge provides a pragmatic approach to alleviating water scarcity while reducing energy consumption and emissions. Across the Middle East, utilities are pairing treatment trains with biogas and heat recovery, and channeling fit-for-purpose effluent into groundwater replenishment strategies that improve water security and stabiliz
Nonlinear resistance during intrusion into solid-like granular matter remains an open problem, challenging the linear drag paradigm underlying widely used models such as Resistive Force Theory (RFT). Here we combine DEM simulations, experiments, and theoretical analysis to uncover the physical origin of this nonlinear response and establish a quantitative theory for its full evolution. We show tha
With increasing population growth and urbanization, the demand for new construction continues to rise. This expansion places significant pressure on the environment. It contributes to reduced daylight and sunlight access, an increase in hard, heat absorbing surfaces, and the deterioration of outdoor thermal comfort. It also exposes urban residents to higher levels of air pollution and noise, while
