Dune slacks are biodiverse seasonal wetlands within sand dune systems, strongly influenced by the dynamics of the local groundwater regime. Future climate predictions indicate strong adverse impact on the hydrology and therefore ecology of these wetland ecosystems. In this study we aimed to find the most appropriate hydrological and ecological indicators to summarise dune slack plant community res
Herein, a model is developed to study the polarization-selective light-coupling in quantum well infrared photodetector arrays with 15 and 30 μm pixel pitch. The polarization-selective light-coupling is achieved using 1D lamella gratings with varying grating orientation and studied through 2D and 3D finite-element method simulations. The extracted absorption quantum efficiency ηabs, derived from th
Background/Objectives: Acute mesenteric ischemia (AMI) is life-threatening and difficult to diagnose in time. Unlike many cardiovascular diseases, the association between lifestyle factors such as diet, alcohol consumption, and physical activity and AMI is unknown. Methods: This study is a prospective cohort study with 28,098 middle-aged participants with a mean follow-up time of 23.1 years. Basel
Even though the one-dimensional contact interaction requires no regularization, renormalization methods have been shown to improve the convergence of numerical calculations considerably. In this work, we compare and contrast these methods: "the running coupling constant"where the two-body ground-state energy is used as a renormalization condition, and two effective interaction approaches that incl
Transit spectroscopy usually relies on the integration of one or several transits to achieve the signal-to-noise ratio (S/N) necessary to resolve spectral features. Consequently, high-S/N observations of exoplanet atmospheres, where we can forgo integration, are essential for disentangling the complex chemistry and dynamics beyond global trends. In this study, we combined two partial 4-UT transits
One of the outstanding goals of the planetary science community is to measure the present-day atmospheric composition of planets and link this back to formation. As giant planets are formed by accreting gas, ices, and rocks, constraining the relative amounts of these components is critical to understand their formation and evolution. For most known planets, including the solar system giants, this
The ferroelectric domain structure of a freestanding BiFeO3 film was visualized by ptychographic dichroic imaging with linearly polarized x-rays at the O K-edge around 530 eV. The dichroic contrast is maximized at the energy of the hybridization of the O 2p state and the Fe 3d orbitals, which is split by the octahedral crystal field of the perovskite structure. The microscopy images thus obtained
Background/Aim: An inverse association exists between type 2 diabetes mellitus (T2DM) and both plasma vitamin D levels and sun exposure, but vitamin D supplementation does not reduce the incidence. We sought to assess whether there is a dose-dependency in the association between sun exposure and T2DM. Patients and Methods: The melanoma in Southern Sweden (MISS) cohort is comprised of one thousand
The discovery of exoplanets has revealed an intriguing class of planets unlike anything in the Solar System: ultra-hot Jupiters. These gas giants share similarities with Jupiter in size and in their hydrogen- and helium-dominated atmospheres, yet their proximity to their host stars results in vastly different atmospheric conditions. Intense stellar radiation heats them to temperatures exceeding 2
Bone strength is a major contributor to fracture risk. Areal bone mineral density (aBMD) obtained from dual-energy X-ray absorptiometry (DXA) is used as a surrogate for bone strength in fracture risk prediction. 3D finite element (FE) models predict bone strength better than aBMD but need 3D computed tomography and are not automated. We have earlier developed a method to automatically reconstruct
Offentliga försäkringar kan göra äktenskap mindre sannolik, men för vem? Med hjälp av American Community Survey finner vi att en ökad sannolikhet att vara berättigad till offentlig hälsoförsäkring på grund av lagförändringar minskar giftermålsfrekvensen, särskilt bland personer med högre utbildningsnivåer. Vi utvecklar en sökmodell av äktenskapsmarknaden som visar att de med ett högt förväntat ekoPublic insurance may disincentivize marriage, but for whom? Using the American Community Survey, we find that an increased likelihood of Medicaid eligibility owing to the Affordable Care Act reduces marriage rates, particularly among people with higher education levels. We develop a search model of the marriage market that shows that those with a high expected financial surplus from marriage respo
The overall aim of this scoping review was to map the existing literature on residual placental blood volume in cesarean sections as an indirect measure of placental transfusion. Multiple databases including Pubmed, Cochrane, Embase and Web of Science were searched for relevant studies published between 1972 and 2023. All studies on cesarean sections with term pregnancies and information on residu
Introduction: Intact cord resuscitation promotes zero separation and facilitates skin-to-skin contact, regardless of delivery mode. Therefore, this study aims to illuminate parents' experiences of intact cord resuscitation in the mother's bed. Method: Interviews with seven mothers, one father and seven couples were analysed using Lindseth and Norberg's phenomenological hermeneutics. Results: The a
BACKGROUND: Long-term oxygen therapy (LTOT) improves survival in patients with chronic severe resting hypoxaemia, but effects on hospitalisation are unknown. This study evaluated the potential impact of starting LTOT on acute exacerbation and hospital burden in patients with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) and pulmonary hypertension (PH).METHODS: Longi
Deoxynivalenol (DON) is a common mycotoxin in crops that could induce intestinal inflammation, affecting the susceptibility of intestinal epithelial cells (IECs) to pathogen infection. This study aimed to investigate DON's effects on mucin and cytokine production as part of the local immune system and how it affected intestinal susceptibility to pathogen infection. Caco-2 cells were exposed to DON
Ethanolamines are often added in the empirical formulation of commercial hard-surface cleaners and degreasers. Their use is usually justified by the fact they are anti-corrosive agents. However, their direct influence on cleaning performance is not well understood. In this work the cleaning performance of formulations with and without mono-ethanolamine (MEA) have been tested on standard polymerize
BACKGROUND: Several widely used drugs have photosensitizing properties, and much research has been conducted to find associations between their use and the risk of developing cutaneous malignant melanoma (cM), basal cell carcinoma (BCC) or cutaneous squamous cell carcinoma (cSCC), often with conflicting results.OBJECTIVE: To assess whether the use of commonly prescribed photosensitizing drugs incr
The increasing demand for renewable energy accounts for the DC microgrid concept, facilitating the integration of photovoltaic (PV) modules and battery energy systems (BESS) into a common DC bus. In light of this, bipolar DC-DC converters can result in two symmetric DC buses that provide more flexibility. This article presents a hybrid bipolar converter by merging a single-ended primary-inductor c
Power converters of DC-DC nature are pivotal to supplying power in electronics, charging equipment, and renewable energy integration along with AC-DC converters. They are frequently used in most of the power supplies of electronic devices as well as dedicated high-energy functionalities including charging battery cells, electroplating, and welding. Furthermore, DC-DC switching regulators not only
