Aim: The primary aim was to investigate the incidence, birth characteristics, and timing of diagnosis of cephalhaematoma (CH). The secondary aim was to explore associations between CH and complications during the neonatal period and infancy. Methods: This is a nationwide population-based register study of infants (< 12 months) born in Sweden from 1997 to 2018. Information was retrieved from health
Fused Filament Fabrication (FFF) is an additive manufacturing process based on Material Extrusion (MEX) of polymeric filament. This manufacturing technology is commonly used for personalized production applications and prototyping, allowing to obtain customized parts with complex geometries at a low cost. However, this production technique has its limitations regarding dimensional accuracy and sur
Increasing extreme heat events in the tropics are creating dangerous environments in schools. There are limited data, however, on the extent of extreme heat in such classrooms and effective heat-mitigation strategies. This study presents the first long-term analysis of classroom temperatures in Ghanaian schools, measuring conditions in 16 classrooms in Accra over 389 days. It highlights the condit
Quality goals have evolved according to the industrial revolution stages from ‘Small Quality’ to ‘Big Quality’ and now to ‘Open Quality’ in the digital transformation era. This study systematically reviews the chronological development of quality paradigms describing how quality management has evolved from Small to Big to Open Quality. We delineate the concept of Open Quality, emphasizing MTCI-bas
Introduction: A Natural Deep Eutectic Solvent (NaDES) is presumably a green and cost-effective eutectic solvent, capable of extracting many different types of analytes. The analyte, apigenin, is a potential nutraceutical compound with anti-diabetic properties. Background: NaDES compositional variation and unknown properties challenges prediction of their extraction selectivity. Aim(s): Correlate N
We explored various methods for inducing quantum dots (QDs) in pure zinc blende (ZB) InAs nanowires. This material exhibits high conductivity due to the presence of an intrinsic accumulation layer of charge carriers, resulting from surface band bending and donor impurities. To create regions that can be depleted by gate potentials (barriers) in the axial direction of the nanowire, we employed both
Fysik är i huvudsak ett studium av dynamiken i världen runt oss, hur saker rör sig och förändras över tid. Det är elektroners dynamik som står i fokus för det här arbetet. Historiskt har det inte varit möjligt att studera elektroners rörelse i detalj på grund av att rörelserna sker på extremt små tidsskalor. Tänk dig en trafikerad gata som du fotograferar två gånger med tio minuters mellanrum. StiThe availability of light pulses down to the attosecond timescale has led to the development of spectroscopic methods capable of resolving the dynamics of electrons. By studying the interference of electron wave packets (EWP) on their natural timescales, greater understanding of the dynamics can be gained. An attosecond pump-probe technique has been applied previously in Lund to study attosecond
Hardware distortion in large intelligent surfaces (LISs) may limit their performance when scaling up such systems. It is of great importance to model the non-ideal effects in their transceivers to study the hardware distortions that can affect their performance. Therefore, we have focused on modeling and studying the effects of nonlinear RX-chains in LISs. We first derive expressions for SNDR of a
We determined the 2025-2040 impact of climate and land use land cover change on streamflow in the Sironko catchment. LULCC was predicted using Cellular Automata Markov. The climate was statistically downscaled from the 29 GCMs of the IPCC Fifth Coupled Model Intercomparison Project using the delta method of the Agricultural Model Inter-comparison and Improvement Project under five climate regimes
Background and purpose: The Measure of Case-Discussion Complexity (MeDiC) tool was created to gauge case complexity at multidisciplinary team meetings (MDTM) for case selection and prioritization. We aimed to assess applicability and association with MeDiC score and non-compliance with national guide-line-recommendations for MDTM referral in a bladder cancer setting. Material and methods: A modifi
Using the EU as case study, we simulate the impact of border carbon adjustments on agri-food markets. While border carbon adjustments alleviate adverse carbon price impacts on EU agricultural competitiveness and emission leakage, our simulation results also reveal that (i) border carbon adjustments may diminish domestic mitigation efforts, thereby partly offsetting benefits from reduced emission l
We summarize the theory and implementation of an open source solver for rotationally symmetric scatterers. The purpose of the code is to compute reference solutions for electrically large radome problems. The rotational symmetry decouples the azimuthal modes, enabling the three-dimensional problem to be broken down into a sequence of decoupled two-dimensional problems which require much less memor

Hafnia-based ferroelectric Field-Effect Transistors (FeFETs) are promising candidates for non-volatile memory and neuromorphic computing due to their fast switching, low power consumption, and CMOS compatibility [1]–[3]. IIIV materials, such as InAs, offer superior electron transport properties [4], [5], and high remnant polarization at low annealing temperatures when integrated with hafnia-based
BACKGROUND: Some per- and polyfluoroalkyl substances (PFAS) such as perfluorohexane sulfonic acid (PFHxS), perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are very long-lived in humans, with serum half-lives of several years. In PFAS hot spots, such as Ronneby, Sweden, high exposures over time have led to markedly elevated serum PFAS levels, which may result in health risks
Background: Cognitive impairment in trauma-affected refugees is often unassessed due to the absence of suitable cross-cultural neuropsychological measures, the high prevalence of psychiatric symptoms, and the need for interpreter mediation. This poses both a clinical challenge and a health inequality for trauma-affected refugees who are left without access to much needed rehabilitation. Untreated
Beyond the main nucleus: the secret lives of micronuclei Imagine your cells diligently copying their precious genetic blueprint every time they divide. This astonishing process, however, is not foolproof. When errors inevitably creep in, especially under stress like radiation or certain drugs, our cells face a terrifying choice: halt operations and attempt repairs or press on, risking chaos. This
