Parents of children with disabilities may face higher labor-market penalties given the extra care and support required. Using Swedish administrative data, we focus on first-born children with Cerebral Palsy (CP) to estimate impacts on parental labor-market outcomes. We apply an event study approach to identify effects up to 10 years after the birth of the child. Our results show that employment an
Context. The bar pattern speed of the LMC has been computed based on data from Gaia DR3 using three different methods. One method suggested that the LMC might be hosting a bar that barely rotates, and is slightly counter-rotating with respect to the disc of the LMC, with a pattern speed of Ωp = −1.0 ± 0.5 km s−1 kpc−1. Aims. We aim to confirm that tidal interactions might prevent the bar hosted by
High-speed vertical In–Ga–As nanowire MOS field-effect transistor (MOSFET) measurements were analyzed through parametric layout models. Measurements from small and large transistors were used to fit dependencies on the number of gate fingers and the number of wires per finger. Extrapolations via intrinsic and parasitic elements reveal the optimal layout for peak frequency performance. To achieve a
How does new technology impact labor market outcomes? We address this question by examining the adoption of electricity in Sweden during the early 20th century. Leveraging detailed individual-level data that covers the entire labor market and exogenous variation in electricity access driven by proximity to hydro-power plants, we estimate the impact of electrification on individual labor market out
Background: Monitoring metabolites of tamoxifen, such as endoxifen, has been suggested as a strategy to ascertain therapeutic effect of tamoxifen therapy, but clinical guidelines are missing. Herein, we aim to investigate the outcome of endoxifen concentrations of low-dose tamoxifen, using change in mammographic breast density as a proxy for therapy response. Methods: In the randomized KARISMA-Tam
The interplay between angular momentum and particle number (which is the equivalent to the angular momentum in gauge space) is studied. The same technique that is used in the case of rotations in ordinary space can be used in gauge space for investigating the properties of individual quasiparticle levels and the total angular momentum of a nucleus. We study the isotopes of Dy and W, where a back-
The strategic role of communication practitioners has been discussedsince the 1970s. While it might not be surprising that managers andcoworkers view their roles as unclear, it is more surprising that commu-nication practitioners themselves also struggle with explaining theirstrategic roles and the value of their work. To elucidate the strategicwork of communication practitioners, we conducted a s
Background: We aimed to study the long-term effect of smoking on coronary atherosclerosis progression at the segmental level. Methods: Angiographic data (1989-2017) on current, former, and nonsmokers were collected from the Swedish Coronary Angiography and Angioplasty Registry. The Western Denmark Heart Registry was used to validate the results. Patients with clinically indicated angiography with
When it comes to random walk on the integers Z, the arguably first step of generalization beyond simple random walk is the class of one-sidedly continuous random walk, where the stepsize in only one direction is bounded by 1. Moreover, the time until state 0 is hit by left-continuous random walk on Z started at 1 has a direct connection to the total progeny in branching processes. In the analysis
The investigation of carbon monoxide (CO) adsorption on the unreconstructed Ir(100)-(1 × 1) surface under ultra-high vacuum (UHV) conditions is studied with scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and high-resolution core-level spectroscopy (HRCLS). At a low coverage of 0.5 ML (monolayer), CO molecules adopt a previously documented c(2 × 2) structure, having CO
This work investigates the interaction between cultural norms and neighborhood characteristics, in the context of the gender gap in math. Using high-quality Swedish administrative data, I estimate the effect of mothers’ country-of-origin gender norms on the gender gap in math among second-generation immigrant siblings and exploit a refugee placement policy to obtain random variation in regional ch
We study the magnetic Laplacian in a two-dimensional exterior domain with Neumann boundary condition and uniform magnetic field. For the exterior of the disk we establish accurate asymptotics of the low-lying eigenvalues in the weak magnetic field limit. For the exterior of a star-shaped domain, we obtain an asymptotic upper bound on the lowest eigenvalue in the weak field limit, involving the 4-m
The chaperone DNAJB6b (JB6) plays important roles in increasing amyloid protein solubility and inhibiting amyloid fibril formation, a causative factor for neurodegenerative diseases like Alzheimer's and Parkinson's disease. Insights into the biophysical properties of JB6, including its structure, self-assembly and stability towards denaturation, may enhance the understanding of the physicochemical
Context: Proneurotensin (pNT) is associated with obesity and type 2 diabetes (T2D), but the effects of Roux-en-Y gastric bypass (RYGB) on postprandial pNT levels are not well studied. Objective: This work aimed to assess the effects of RYGB vs a very low-energy diet (VLED) on pNT levels in response to mixed-meal tests (MMTs), and long-term effects of RYGB on fasting pNT. Methods: Cohort 1: Nine no
What is the political significance of literature? How, if at all, can fictional narratives interact with issues of social and legal justice? This paper addresses these questions and proposes four models of literature's intervention in political reality based on Walter Benjamin’s and Günther Anders’ readings of Kafka. According to Benjamin’s 1930s Kafka essays, fictional narratives have the power t
Challenges of intonation derive from discrepancies between justly tuned intervals. In theoretical literature, string intonation is depicted as a balancing act between melodic and harmonic ideals, or between distinct tuning systems. However, practical string teachers’ and empirical researchers’ accounts sometimes appear to bypass such theory, focusing instead more informally on listening, kinesthet
