An Empirically Grounded Path Forward for Scenario-Based Testing of Autonomous Driving Systems

Testing of autonomous driving systems (ADS) is a crucial, yet complex task that requires different approaches to ensure the safety and reliability of the system in various driving scenarios. Currently, there is a lack of understanding of the industry practices for testing such systems, and also the related challenges. To this end, we conduct a secondary analysis of our previous exploratory study,

Water Nanochannels in Ultrathin Clinochlore Phyllosilicate Mineral with Ice-like Behavior

Water is the matrix of life, and its confinement in nanocavities is a central topic from geophysics to nanotribology. Phyllosilicate layered minerals provide natural nanocavities for water due to their capacity to hydrate by confining water molecules in the interlamellar space. However, the hydration of phyllosilicates at the nanoscale is not a fully understood process and depends on the geologica

Colonialism in South Africa leaves a lasting legacy of reduced genetic diversity in Cape buffalo

The iconic Cape buffalo has experienced several documented population declines in recent history. These declines have been largely attributed to the late 19th century rinderpest pandemic. However, the effect of the rinderpest pandemic on their genetic diversity remains contentious, and other factors that have potentially affected this diversity include environmental changes during the Pleistocene,

Induction of murine experimental autoimmune myocarditis – technical details, implementation and evaluation

Introduction: Myocarditis is a complex cardiac disorder with multifactorial etiology, characterized by myocardial inflammation, cardiomyocyte damage, and fibrosis. Left untreated, myocarditis may lead to acute and chronic heart failure and life-threatening arrhythmias. Reliable experimental models of myocarditis are required to study the underlying pathological mechanisms of the disease and to dev

Land use modelling needs to better account for multiple cropping to inform pathways for sustainable agriculture

Multiple cropping, the simultaneous cultivation of several crops in space or time, is a global practice essential for intensifying and diversifying agriculture. Despite its substantial impact on environmental and socioeconomic outcomes of farming, multiple cropping is hardly accounted for in assessments of global food production, sustainability, and climate impacts. Such studies, often relying on

How energy and chemistry converge for a fossil-free future

The chemical industry must undergo a dual transformation: electrifying energy use and defossilizing carbon feedstocks. This paper, developed by ENGIEs Scientific Council, examines how energy and chemistry can converge to enable this shift. We assess the roles of biomass, recycled plastics, and CO2 as sustainable carbon sources and explore the enabling potential of electrification, low-carbon hydro

Super-resolution stimulated X-ray Raman spectroscopy

Propagation of intense X-ray pulses through dense media has led to the observation of phenomena such as atomic X-ray lasing1,2, self-induced transparency3 and stimulated X-ray Raman scattering (SXRS)4. SXRS has been long predicted as a means to launch and probe valence-electron wavepackets and as a building block for nonlinear X-ray spectroscopies5,6. However, experimental observations of SXRS to

Structural insights into AQP3 channel closure upon pH and redox changes reveal an autoregulatory molecular mechanism

Regulation of intracellular levels of reactive oxygen species (ROS) remains poorly understood. Aquaporin 3 (AQP3) facilitates the membrane transport of hydrogen peroxide (H2O2), a key ROS signaling molecule. Here we elucidate the molecular mechanism of AQP3 and show that its regulatory properties are both pH dependent and autoregulated by H2O2. Using single particle cryo-electron microscopy, we pr

Alpha synuclein co-pathology is associated with accelerated amyloid-driven tau accumulation in Alzheimer’s disease

Background: Aggregated alpha-Synuclein (αSyn) is a hallmark pathology in Parkinson’s disease but also one of the most common co-pathologies in Alzheimer’s disease (AD). Preclinical studies suggest that αSyn can exacerbate tau aggregation, implying that αSyn co-pathology may specifically contribute to the Aβ-induced aggregation of tau that drives neurodegeneration and cognitive decline in AD. To in

Differences in sexual violence against younger and older adults in complex humanitarian settings : a retrospective analysis from Médecins Sans Frontières in 2019-24

BACKGROUND: Sexual violence against older adults in humanitarian settings is poorly documented, leading to gaps in prevention and delivery of support services. This study aimed to document differences in assault characteristics between younger and older adults, by sex and displacement and disability status and region. METHODS: This retrospective, descriptive observational, multi-country study incl

Kinetics of Biomarkers for Therapeutic Assessment in Swiss Mice Infected with a Virulent Trypanosoma cruzi Strain.

Chagas disease (CD), caused by Trypanosoma cruzi, is a neglected tropical illness affecting 6-8 million people in Latin America. Reaching scholarly consensus on the host response to T. cruzi infection remains a significant challenge, primarily due to substantial heterogeneity in outcomes driven by both the choice of animal model and the infecting parasite's discrete typing unit (DTU). This varia

The Role of RB1 and Secondary Genomic Changes in the Development of Spindle Cell and Pleomorphic Lipomas

Spindle cell lipomas (SCL) and pleomorphic lipomas (PL) are today considered a single tumor entity (SCLPL). Atypical SCLPL, in contrast, represents a recently recognized related but distinct entity. Here we explored the correlation between genomic features and morphological aspects of SCLPL and atypical SCLPL and the role of the RB1 gene in tumor development. Seventy-one samples from 68 patients w

Stellar ages, masses, extinctions, and orbital parameters based on spectroscopic parameters of Gaia DR3

Context.Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these allow us to derive orbital and stellar parameters that are key to understanding the stellar populations of the Milky Way and to perform Galactic archaeology. Aims. We used the calibrate

Assessment of exposure determinants and exposure levels by using stationary concentration measurements and a probabilistic near-field/far-field exposure model

Background: The Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation requires the establishment of Conditions of Use (CoU) for all exposure scenarios to ensure good communication of safe working practices. Setting CoU requires the risk assessment of all relevant Contributing Scenarios (CSs) in the exposure scenario. A new CS has to be created whenever an Operatio

Prolonged culture of human pancreatic islets under glucotoxic conditions changes their acute beta cell calcium and insulin secretion glucose response curves from sigmoid to bell-shaped

Aims/hypothesis: The rapid remission of type 2 diabetes by a diet very low in energy correlates with a marked improvement in glucose-stimulated insulin secretion (GSIS), emphasising the role of beta cell dysfunction in the early stages of the disease. In search of novel mechanisms of beta cell dysfunction after long-term exposure to mild to severe glucotoxic conditions, we extensively characterise

Short-acting β2-agonist use and asthma exacerbations in Swedish children : A SABINA Junior study

Background: In adults and adolescents with asthma, use of ≥3 short-acting β2-agonist (SABA) canisters/year is associated with increased exacerbation risk. Whether this association is present in younger children remains unknown. In this SABA use IN Asthma (SABINA) Junior study, we assessed the association of SABA collection with exacerbation risk in the general Swedish pediatric asthma population.

Chromosome-scale genome assembly of the brown anole (Anolis sagrei), an emerging model species

Rapid technological improvements are democratizing access to high quality, chromosome-scale genome assemblies. No longer the domain of only the most highly studied model organisms, now non-traditional and emerging model species can be genome-enabled using a combination of sequencing technologies and assembly software. Consequently, old ideas built on sparse sampling across the tree of life have re

The Long Non-Coding Antisense RNA JHDM1D-AS1 Regulates Inflammatory Responses in Human Monocytes

Monocytes are key players in innate immunity, with their ability to regulate inflammatory responses and combat invading pathogens. There is a growing body of evidence indicating that long non-coding RNA (lncRNA) participate in various cellular biological processes, including the innate immune response. The immunoregulatory properties of numerous lncRNAs discovered in monocytes remain largely unexp
