The effects of oxygen concentration on combustion of gases have been investigated on fundamental levels in several studies. However, the same type of fundamental studies has not been made for liquid or solid fuels due to complex relationships between flame structure and changing mass loss rates (MLR). In this study, an experimental setup is designed that allows for extended times of stable combust
Southern Africa is a global hotspot for hydrometeorological risk, with intensifying droughts and floods increasingly disrupting livelihoods, ecosystems, and infrastructure. This study presents a systematic bibliometric and scientometric synthesis of 1481 peer-reviewed publications on drought and flood hazards published between 2000 and 2024 across the Southern African Development Community. Using
Background: Early identification of patients with suspected infection who are at risk of clinical deterioration in the Emergency Department (ED) is challenging, yet crucial for timely initiation of appropriate care and prevention of clinical deterioration. This multicenter international study evaluates the performance of established scores (SIRS, LODS, qSOFA, SOFA, NEWS) in predicting severe outco
The viability of a main-group triple bond depends critically on the strength of its π-manifold. Among the 15 possible diatomic homo- and interpnictogens, EE′, (E, E′ = group 15 element), the NN linkage of dinitrogen stands out as one of the strongest triple bonds that exists, whereas the heavier pnictogens form thermodynamically unstable triple bond motifs that either decompose to single-bonded ol
Photon counting computed tomography (PCCT) provides exceptional image quality with reduced radiation dose in temporal bone imaging and is emerging as a potential new gold standard. This study aims to assess the feasibility of an in-house micro-computed tomography (micro-CT) system equipped with Photon Counting Detector (PCD) technology and to compare it with a clinical PCCT scanner for temporal bo
Accurate prediction of groundwater levels (GWL) is essential for effective and sustainable water resource management, particularly in arid and semiarid regions where excessive extraction and climate change significantly accelerate aquifer depletion. The nonstationary characteristics of groundwater data pose significant challenges to the performance and reliability of conventional machine learning
Species of the Mycobacterium avium complex display two main colony morphologies, smooth transparent (SmT) and smooth opaque (SmO), where SmT is associated with human disease and antimicrobial resistance. Previous studies have suggested that smooth bacteria can reversibly switch between the transparent and opaque forms, but the mechanism underlying morphotype transition has remained unknown. Using
Three plant researchers describe in this book how plants emerged via the fusion of several different types of simple prokaryotic organisms and, through algae, evolved into land plants. During their evolution, they survived global ice ages, violent volcanic eruptions, and collisions with celestial bodies. The authors follow the development of landplants along various paths- some of which have ended
A 47-year-old woman with metastatic pancreatic adenocarcinoma, diagnosed five months earlier and treated with palliative chemotherapy, was admitted with fever, jaundice, and right upper quadrant pain consistent with ascending cholangitis. Treatment with antibiotics was initiated and an endoscopic retrograde cholangiography was performed, whereby a biliary stent was placed to relieve malignant bili
Objectives: SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss-of-function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes. Here we describe a novel dominant variant in SLC4A4 in patients wit
Background: T cell receptor (TCR) binding properties have been related to a wide range of pathological conditions, including infections, autoimmunity and cancer. Characterising the TCR repertoire is of great biomedical interest but it has been challenging due to its high structural diversity. Methods: In situ sequencing (ISS) is a suitable technique for spatial cell typing and linking gene pattern
Osteoarthritis (OA)-related meniscal degeneration involves complex interactions between oxidative stress and proteasomal dysfunction. However, the molecular drivers of regional meniscal vulnerability remain poorly defined. This study integrated multiple transcriptomic datasets from OA and control menisci to identify functional networks and hub genes by using weighted gene co-expression network ana
The dissociation of NO is a critical step in its catalytic reduction to N2, which is key to automotive exhaust treatment. Here, we examine the role of Rh atomic steps in the NO dissociation reaction under 0.05 mbar NO. We use a Rh crystal sample curved around the (111) direction and ambient-pressure X-ray photoelectron spectroscopy to probe different Rh surfaces subject to the very same reaction c
OBJECTIVES: We assessed the prevalence of neurodevelopmental disabilities (NDDs; cognition, cerebral palsy, vision/hearing, epilepsy), attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), developmental coordination disorder (DCD), behavior problems, and multimorbidity in a national cohort of children born extremely preterm (EPT, <27-week gestation) to provide a comprehe
Cognitive scientists Spelke and Kintzler (2007) and Carey (2009) identify objects, actions, space and numbers as “core domains of knowledge” that are essential for conceptualizing the world. Gärdenfors (2019, 2020) argues that objects, actions and space are characterized by invariances in sensory signals. In this paper, we extend the analysis of invariances to the domain of numbers (understood as
Background: Randomized trials have demonstrated that early anticoagulation after acute atrial fibrillation-associated ischemic stroke is safe and non-inferior to delayed initiation. Whether anticoagulation should be delayed in people with larger infarcts is uncertain. Aims: To investigate whether ischemic stroke infarct volume, measured precisely by segmentation, modifies the treatment effect of e
We employ small-angle x-ray and dynamic light scattering to investigate the microscopic structure and dynamics of dense suspensions of ultra-low crosslinked (ULC) poly(N-isopropylacrylamide) microgels. By probing the supercooled and glassy regimes, we characterize the relationship between the structure and dynamics as a function of effective volume fraction φ and probed length scale. We demonstrat
Many animals, such as birds and bats, are capable of migrating over vast distances to specific destinations. Remarkably, even insects such as the North American Monarch butterfly and the Australian Bogong moth undertake similarly long-distance migrations to specific sites. Here, we provide an overview of our current understanding of the migration of these insects and outline the sensory cues and n
