In this paper the connection between exogamy and partnership dissolution is analyzed using individual level register data for natives and immigrants moving to Sweden after 1968. We study both formally married and cohabiting unions, from the birth of the first child until dissolution of the partnership. Using event history models we study the impact of type of union (endogamous, exogamous with a na

People often draw inferences from sequences of past performance, sometimes perceiving patterns even in random outcomes. This has fueled debates regarding phenomena such as the hot hand and gambler’s fallacies. With the growing use of artificial intelligence (AI) systems for forecasting and decision support, it becomes important to understand how people form beliefs from sequences of outcomes attri

Research on episodic memory shows that people often direct their gaze toward locations where goal-relevant information was originally encoded, even in the absence of visual input. This “looking-at-nothing” (LAN) behavior has been demonstrated to strengthen maintenance of visuospatial configurations (Olsen et al., 2014; Wynn et al., 2018), enhance the accuracy and fidelity of episodic recall (Johan

Context. Despite the ever-increasing number of known exoplanets, no uncontested detections have been made of their satellites, known as exomoons. Aims. The quest to find exomoons is at the forefront of exoplanetary sciences. Certain space-born instruments are thought to be suitable for this purpose. We show the progress made with the CHaracterising ExOPlanets Satellite (CHEOPS) in this field using

Aims. We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star on a relatively long orbit of 18.26 days, by combining new photometric and spectroscopic observations. Methods. We analyzed new space-based photometry from TESS and CHEOPS, as well as 61 radial velocity measurements from HARPS-N. We performed individu

Many different types of insects make seasonal migrations over vast distances, typically from one broad geographical region to another, most often involving a latitudinal change in one direction in spring with a reversal of this direction in autumn. However, a small handful of these species instead migrate from an enormous geographical area to a highly specific destination they have never previousl

In recognition of outstanding articles published in the Journal of Comparative Physiology A, Editors’ and Readers’ Choice Awards are conferred annually to the top papers in the categories Original Research Paper and Review/Review-History Article. The recipients of the 2026 Editors’ Choice Awards were selected based on votes cast by the Editorial Board on articles published in 2025. In the category

Why are some men attracted to misogynistic groups? Drawing on literature on intergroup threat, we hypothesize that men who perceive that their status is threatened are more likely to engage with misogynistic groups. We also hypothesize that anger reactions to such threats is an important mechanism explaining why perceived masculine status threats lead to such engagement. In a survey (N = 2,751) we

The Economic Dispatch Problem (EDP) plays a critical role in power system operations by trying to allocate power generation across multiple units at minimal cost while satisfying complex operational constraints. Traditional optimization techniques struggle with the non-convexities introduced by factors such as valve-point effects, prohibited operating zones, and spinning reserve requirements. Whil

The use of Large Language Models (LLMs) such as ChatGPT is a prominent topicin higher education, prompting debate over their educational impact. Studies onthe effect of LLMs on learning in higher education often rely on self-reported data,leaving an opening for complimentary methodologies. This study contributes byanalysing actual course grades as well as ratings by fellow students to investigateh

The radioactive noble gas radon (222Rn) is a suitable tracer for atmospheric transport and mixing processes that can be used to evaluate and calibrate atmospheric transport models or to estimate greenhouse gas (GHG) emissions using the so-called radon tracer method (RTM). However, these applications require reliable estimates of the 222Rn fluxes from the soil. This study evaluates two process-base

Atmospheric measurements of the short-lived radioactive noble gas radon-222 (222Rn) have many applications. Its concentrations are driven by atmospheric mixing as well as seasonal variations, which follow the seasonality of 222Rn exhalation from continental soils, with lower values during the wet winter and spring months compared to more dry summer conditions. Hence, it can be used as a tracer to

Here, we use carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), nitrous oxide (N2O) and radon (222Rn) data from the Saclay ICOS tall tower in France to estimate CO2, CH4 and CO fluxes within the station footprint from January 2017 to October 2024 and N2O fluxes from February 2019 to October 2024 using the Radon Tracer Method (RTM). We first performed a sensitivity study of this method appl

For the development of a joint European capacity for monitoring CO2 emissions, we created the framework “CO2 Monitoring Challenges City Mapbooks v1.0” (CMC-CITYMAP). It includes a Jupyter notebook tool (Storm et al., 2025a, https://doi.org/10.18160/P8SV-B99F) which we use to characterise and cluster cities based on aspects relevant for different CO2 monitoring challenges. These include:a. determin

This paper presents a novel approach to economic dispatch (ED) optimization in power systems through the application of Proximal Policy Optimization (PPO), an advanced reinforcement learning algorithm. The economic dispatch problem, a fundamental challenge in power system operations, involves optimizing the generation output of multiple units to minimize operational costs while satisfying load dem

Adaptive network dynamical systems describe the co-evolution of dynamical quantities on the nodes and the dynamics of the network connections themselves. For dense networks of many nodes, the resulting dynamics are typically high-dimensional. Here, we consider adaptive dynamical systems subject to constraints on network adaptation: Asymptotically, the adaptive dynamics of network connections evolv

The Lepidoptera, butterflies and moths, display an astonishing diversity of spatial orientation strategies essential for survival, reproduction, and ecological success. These spatial orientation strategies range from basic taxes to light, wind, gravity, and chemical cues, to more advanced strategies such as straight-line dispersal, multigenerational migration across continents, and complex trap-li

The purpose of cancer screening is to reduce mortality, and ideally incidence, from the cancer screened for. Until recently, cancer screening has been offered to all persons in pre-defined sex- and age-groups. The exception is lung screening which is targeted to high-risk individuals. Evidence for effect of screening on cancer-specific mortality is available for cancer of the cervix, breast, color
