Volcanic temperature changes modulated volatile release and climate fluctuations at the end-Triassic mass extinction
Emplacement of the Central Atlantic Magmatic Province (CAMP) is thought to have triggered global environmental changes and the end-Triassic mass extinction (ETE). However, the mechanisms linking volcanism and environmental change are unclear. Here we provide new insight into these linkages by measuring the abundance of both sedimentary five- to six-ring polycyclic aromatic hydrocarbons (PAHs) and
Early and late-onset syncope : insight into mechanisms
AIMS: Unexplained syncope is an important clinical challenge. The influence of age at first syncope on the final syncope diagnosis is not well studied.METHODS AND RESULTS: Consecutive head-up tilt patients (n = 1928) evaluated for unexplained syncope were stratified into age groups
Multi-scattering software part II : Experimental validation for the light intensity distribution
This article, Part II of an article series on GPU-accelerated Monte Carlo simulation of photon transport through turbid media, focuses on the validation of the online software Multi-Scattering. While Part I detailed the implementation of the computational model, simulated and experimental results are now compared for the distribution of the scattered light intensity. The scattering phantoms prepar
Human impacts and their interactions in the Baltic Sea region
Coastal environments, in particular heavily populated semi-enclosed marginal seas and coasts like the Baltic Sea region, are strongly affected by human activities. A multitude of human impacts, including climate change, affect the different compartments of the environment, and these effects interact with each other. As part of the Baltic Earth Assessment Reports (BEAR), we present an inventory and
Azimuthal correlations of high transverse momentum jets at next-to-leading order in the parton branching method
The azimuthal correlation, Δ ϕ12, of high transverse momentum jets in pp collisions at s=13 TeV is studied by applying PB-TMD distributions to NLO calculations via MCatNLO together with the PB-TMD parton shower. A very good description of the cross section as a function of Δ ϕ12 is observed. In the back-to-back region of Δ ϕ12→ π, a very good agreement is observed with the PB-TMD Set 2 distributio
Cold-induced anesthesia impairs path integration memory in dung beetles
Path integration is a general mechanism used by many animals to maintain an updated record of their position in relation to a set reference point.1–11 To do this, they continually integrate direction and distance information into a memorized home vector. What remains unclear is how this vector is stored, maintained, and utilized for successful navigation. A recent computational model based on the

Large gaps in the quality of healthcare experienced by Swedish mothers during the COVID-19 pandemic : A cross-sectional study based on WHO standards
Background and Problem: Existing healthcare systems have been put under immense pressure during the COVID-19 pandemic. Disruptions in essential maternal and newborn services have come from even high-income countries within the World Health Organization (WHO) European Region. Aim: To describe the quality of care during pregnancy and childbirth, as reported by the women themselves, during the COVID-

Ribosomal biogenesis regulator DIMT1 controls β-cell protein synthesis, mitochondrial function, and insulin secretion
We previously reported that loss of mitochondrial transcription factor B1 (TFB1M) leads to mitochondrial dysfunction and is involved in the pathogenesis of type 2 diabetes (T2D). Whether defects in ribosomal processing impact mitochondrial function and could play a pathogenetic role in β-cells and T2D is not known. To this end, we explored expression and the functional role of dimethyladenosine tr

Antisemitism on Social Media Platforms : Placing the Problem into Perspective
This chapter provides a survey of the existing quantitative research on antisemitism and social media. Through doing so, it argues that the sheer quantity of antisemitism on social media is much less than commonly perceived. In addition, the chapter argues that quantitative research often neglects counter-narratives calling out antisemitism, which are an important counterpoint to include in antise
Stability and phase transitions of dynamical flow networks with finite capacities
We study deterministic continuous-time lossy dynamical flow networks with constant exogenous demands, fixed routing, and finite flow and buffer capacities. In the considered model, when the total net flow in a cell —consisting of the difference between the total flow directed towards it minus the outflow from it— exceeds a certain capacity constraint, then the exceeding part of it leaks out of the
Controlling network coordination games
We study a novel control problem in the context of network coordination games: the individuation of the smallest set of players capable of driving the system, globally, from one Nash equilibrium to another one. Our main contribution is the design of a randomized algorithm based on a time-reversible Markov chain with provable convergence guarantees.
Marketization in Crisis : The Political Economy of COVID-19 and the Unmaking of Public Transport in Stockholm
While measures to prevent the spread of COVID-19 disturbed both global and local markets, some commentators also argued that the pandemic could be seen as the beginning of the end of neoliberalism. Although neoliberal reforms have come under pressure, little is known about the implications of COVID-19 in or across specific sectors. Scaling down the rich theoretical–historical debates about neolibe
Incident cardiovascular disease and long-term exposure to source-specific air pollutants in a Swedish cohort
Air pollution is associated with cardiovascular morbidity and mortality, but its role in the development of congestive heart failure (CHF) and the role of different pollution sources in cardiovascular disease remain uncertain.MethodsParticipants were enrolled in the Malmö Diet and Cancer cohort in 1991–1996 with information on lifestyle and clinical indicators of cardiovascular disease.

Accelerating research on biological aging and mental health : Current challenges and future directions
Aging is associated with complex biological changes that can be accelerated, slowed, or even temporarily reversed by biological and non-biological factors. This article focuses on the link between biological aging, psychological stressors, and mental illness. Rather than comprehensively reviewing this rapidly expanding field, we highlight challenges in this area of research and propose potential s
