Solar photospheric spectrum microvariability : I. Theoretical searches for proxies of radial-velocity jittering

Context. Extreme precision radial-velocity spectrometers enable extreme precision in stellar spectroscopy. Searches for low-mass exoplanets around solar-type stars are limited by various types of physical variability in stellar spectra, such as the short-term jittering of apparent radial velocities on levels of ∼2 m s-1. Aims. To understand the physical origins of radial-velocity jittering, the so

Evidence of Site-Specific and Male-Biased Germline Mutation Rate in a Wild Songbird

Germline mutations are the ultimate source of genetic variation and the raw material for organismal evolution. Despite their significance, the frequency and genomic locations of mutations, as well as potential sex bias, are yet to be widely investigated in most species. To address these gaps, we conducted whole-genome sequencing of 12 great reed warblers (Acrocephalus arundinaceus) in a pedigree s

Staten och maten - kan skatter och subventioner rädda liv?

Kostintaget i Sverige följer inte Livsmedelsverkets rekommendationer. I den här studien undersöker vi om skatter och subventioner på livsmedel kan påverka människors matvanor och hälsa. Vi studerar skatter på produkter med hög andel mättade fetter och på produkter med hög andel salt, och hur de är relaterade till dödsfall från kostrelaterade sjukdomar. Vi undersöker även i vilken utsträckning subv

A decade of maize yield gap studies in sub-Saharan Africa: how are farm-level factors considered?

The study of yield gaps has become more complex, prompting the use of varied approaches to measure yields and a wider range of factors to explain these gaps. In the Global North, the focus is on precision farming, whereas in sub-Saharan Africa (SSA), a broader perspective is necessary due to pronounced variability in farmland conditions. While biogeophysical and management factors have been tradit

Interface reduction technique for Enhanced Craig-Bampton method

Substructure coupling and model order reduction using Component Mode Synthesis (CMS) have, over recent years, gained considerable attention in the vibroacoustic analysis of complex structures. In the CMS methodology, the interior dynamics of each subcomponent in a substructured system are represented by a truncated set of normal modes within the lower frequency range, while all physical degrees of

Traceable calibration with 177Lu and comparison of activity meters at hospitals in Norway and Sweden

Introduction: The activity meter is used to determine the activity of delivered radiopharmaceuticals, administered activity to patients and reference activity when gamma-cameras are calibrated prior to imaged-based dosimetry. The aim is to describe a procedure for cross-calibration of activity meters at different clinical sites, and report on 177Lu activity results when using factory-set calibrati

Multiplicity of grain boundary structures and related energy variations

Ideal minimum-energy grain boundary (GB) structures are usually the only ones considered when characterizing GBs. This limited perspective provides an incomplete view of the possible structural variability of GBs. In the present study, phase field crystal (PFC) simulations are employed in a systematic search of GB states based on -surface sampling, demonstrating PFC to be a capable tool for this p

ALK signaling primes the DNA damage response sensitizing ALK-driven neuroblastoma to therapeutic ATR inhibition

High-risk neuroblastoma (NB) is a significant clinical challenge. MYCN and Anaplastic Lymphoma Kinase (ALK), which are often involved in high-risk NB, lead to increased replication stress in cancer cells, suggesting therapeutic strategies. We previously identified an ATR (ataxia telangiectasia and Rad3-related)/ALK inhibitor (ATRi/ALKi) combination as such a strategy in two independent genetically

Taxonomical lives : The making of social divisions in the Swedish press during the golden age of social democracy, 1945–76

This article investigates the media lives of a particular class taxonomy in the Swedish press from 1945 to 1976. Invented by the Central Bureau of Statistics in 1911, the ‘social group division’ system was abandoned in the early post-war period. Around the same time, however, it gained popularity in Swedish culture and political debate. While earlier research has noted that such bureaucratic class

A sense of seaweed : Consumer liking of bread and spreads with the addition of four different species of northern European seaweeds. A pilot study among Swedish consumers.

Current food systems pose one of the greatest health and environmental challenges of the 21st century. Expanded utilization of seaweed for food in Western societies seems like one promising measure in the transition toward sustainable food systems. However, introducing and expanding seaweed to new markets brings certain challenges, such as limited food acceptance and availability.

Triaxial superdeformed bands in [Formula Presented]

Four new superdeformed bands have been found in the nucleus [Formula Presented]. The good agreement between experiment and configuration-dependent shell correction calculations suggests that three of the bands have triaxial superdeformed shapes. Such unique features in mass [Formula Presented] superdeformed bands have been predicted, but not observed experimentally until now. A fourth band in [For
