Estimating Abilities With an Elo-Informed Growth Model

Two common methods for modeling abilities that change over time are generalized linear mixed models (GLMMs) and the Elo algorithm. GLMM specifications that avoid assumptions about the shape of the growth curve tend to be computationally heavy. The Elo algorithm is both flexible a...

JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova

Abstract We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from ∼2 weeks before to ∼1 yr after maximum light. JWST near- and mid-infrared spectra at +276 and +363 days show ∼400 K dust emission that cools by ∼75 K between epochs, the first una...

A twin study of employment uncertainty and sickness absence due to mental disorders accounting for familial factors and personality

Abstract While both insecure employments and sickness absence due to mood, anxiety, and stress-related disorders are common on the labor market and pose major public health concerns, their interrelations are not well understood. This prospective twin study examined the associatio...

An Arctic climatology of particle number size distributions and cloud condensation nuclei during warm and moist intrusions

Abstract Recent studies indicate that warm and moist intrusions are significant sources of aerosols in the Arctic. Yet their contribution to different aerosol particle size modes, cloud condensation nuclei (CCN), and droplet number concentrations ( N d ) remains largely unconstra...

Database Mining Reveals Distinct Clusters of Putative Diphthamide-Specific Mono-ADP-Ribosylating Toxins in Vibrio and Aeromonas

Diphthamide-specific mono-ADP-ribosylating toxins form a structurally conserved but phylogenetically diverse family of AB-type bacterial toxins, with Pseudomonas exotoxin A (PE) serving as a prototypical member. Here, we expand the known diversity of PE-like toxins (PLTs) through...

Deadwood Labor? The Effects of Eliminating Employment Protection for Older Workers

We analyze mandatory retirement in Sweden, which eliminates employment protection at age 67. Employment falls by about 10 percent and total average earnings by about 20 percent immediately at age 67. Eight percent of jobs separate immediately due to loss of protection, with effec...

The Complex Interplay of Duration of Residence and Region of Birth on Perinatal Outcomes Among Migrant Women in Australia: A Cohort Study

ABSTRACT Background Although migrants are recognised as heterogeneous, research often emphasises origin over receiving‐context experiences. Objectives We investigated maternal risk factors and perinatal outcomes by duration of residence in Australia, stratified by region of birth...

Important features in attractive user interface in e-learning Systems: A case study of Swedish Language learning System, "Interaktiv Svenska"

The students’ success in learning not only affected by their skills, but there is also a number of important relative factors, like learning environment, teachers’ instructional methods and course materials. These days with the advanced technology, computer systems have been used...

Family economic security after the COVID-19 outbreak: unions, work-life balance policies and employment outcomes

Unionization has been associated with benefits to workers, including higher wages compared to non-unionized workers and greater access to family-friendly work arrangements. In this paper, we consider another potential benefit of union representation by examining whether and how u...

Using Formal and Computational Modelling to Develop an Initial Within-Person System Dynamics Model of Relapse in Smoking Cessation: A Participatory, Iterative, Multi-Method Approach

Popular relapse prevention theories are represented using natural language descriptions and lack temporal information about how phenomena of interest (i.e., ‘relapse’, ‘prolapse’, ‘abstinence’) are dynamically caused over time and within individuals. We drew on the Theory Constru...

Frailty and longitudinal pulmonary function trajectories in lung transplant recipients

Abstract Background Frailty is increasingly recognized as a marker of biological vulnerability associated with adverse clinical outcomes. Lung transplant recipients may be particularly susceptible to frailty, yet its impact on longitudinal pulmonary function improvement after tra...

SN 2024iss: A Multiwavelength Exposé of a Type IIb Supernova with an Early-time Ultraviolet Spectrum and Shock-breakout Constraints

Abstract We present multiwavelength observations and analysis of SN 2024iss, a Type IIb supernova (SN IIb) located at ∼14 Mpc. The first Zwicky Transient Facility detection of SN 2024iss is ∼40 minutes after first light (one of the earliest detections of a SN IIb to date) and a H...

Candidate Structure Prioritization in Non-Target Screening with Predicted Collision Cross-Sections and Uncertainty Quantification

Abstract Candidate structure prioritization in non-target screening (NTS) can be performed using collision cross-sections (CCSs) predicted by a machine-learning (ML) model, with a threshold on the relative difference between measured and in silico CCSs. Such thresholds generally...

Atlas of cell types and regulatory elements underlying human facial diversity

Abstract Human genetic diversity generates an astonishing variety of facial shapes, and craniofacial anomalies rank among the most common birth defects. Identifying the cellular mechanisms that mediate the genome’s influence on facial variation remains a challenge. Here we create...

Effect of pea protein-enriched snacks and vitamin D supplementation on the progression of sarcopenia in elderly subjects: study protocol of the SARC-PEA randomised controlled trial

The progressive ageing of the population (age > 65 years) underscores the urgent need for effective strategies for the prevention of sarcopenia, a condition characterised by the gradual loss of muscle mass and muscle strength and a decline in physical performance. Adequate intake...

Probiotics and Risk of Death, Necrotizing Enterocolitis, and Sepsis in Very Preterm Infants

Importance Probiotics are reported to benefit preterm infants, but population-based clinical evidence is limited. In 2020, the Swedish Neonatal Society issued a national recommendation to supplement very preterm infants (28 weeks 0 days’ to 31 weeks 6 days’ gestation) with probio...

The key to scientific understanding: DEKI and stability

This paper combines discussions of scientific representation and scientific understanding. While both topics have generated substantial philosophical debate, the systematic relationships between philosophical accounts of each have been underexplored. We take a step in connecting...

FREE ACTIONS OF POLYNOMIAL GROWTH LIE GROUPS AND CLASSIFIABLE C*-ALGEBRAS

Abstract We show that any free action of a connected Lie group of polynomial growth on a finite dimensional locally compact space has finite tube dimension. This is shown to imply that the associated crossed product C*-algebra has finite nuclear dimension. As an application we sh...

Socioeconomic Status and Working Life Expectancy: A Swedish Cohort Study

Abstract Longer life expectancy and fertility decline raise several potential challenges for national economies and the security of welfare systems. Raising retirement ages, or ages of eligibility for state pension, is one strategy to offset rising costs. Yet, considerable subgro...
