The cranked Nilsson-Strutinsky formalism is applied to the many-faceted spectrum of 16O. The deformation parameters ε{lunate}, γ and ε4 are varied independently and many-particle-many-hole excitations are considered in the rotating system. Potential-energy surfaces are presented at different values of spin, parity and signature. Surprisingly good agreement is obtained when the different minima are
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-
Using a survey of 5,504 respondents from 22 European countries, we examine preferences regarding cash and cashless payments at the point of sale (POS) during the COVID-19 crisis. Consumers favor cashless transactions when they believe that handling cash presents a higher risk of infection. Moreover, the habits they develop during periods of restrictions and lockdowns appear to further diminish the
I denna avhandling undersöks opinionsundersökningens introduktion i Sverige under mitten av 1900-talet. Fokus ligger på Svenska Gallupinstitutet AB, som 1941 etablerades som landets första opinionsinstitut och som introducerade den urvalsbaserade enkätundersökningen som ett nytt medium genom vilket den allmänna opinionen kunde representeras. De hade i princip monopol på området till 1950-talets miThis thesis examines the introduction and impact of opinion polling in Sweden during the mid-twentieth century, focusing on the activities of the Swedish Gallup Institute (Svenska Gallupinstitutet). Established in 1941 as the country’s first polling organization, the institute introduced sample surveys as a new means of representing public opinion and had a near-monopoly on polling until its decli
Quality goals have evolved according to the industrial revolution stages from ‘Small Quality’ to ‘Big Quality’ and now to ‘Open Quality’ in the digital transformation era. This study systematically reviews the chronological development of quality paradigms describing how quality management has evolved from Small to Big to Open Quality. We delineate the concept of Open Quality, emphasizing MTCI-bas
This article exposes the invisible sand that underpins Copenhagen’s transformation from fishing village to global city. By “following sand,” we trace how planetary material flows sustain urban expansion while entangling the city in processes of capital accumulation, class restructuring, and ecological degradation. Drawing on Science and Technology Studies (STS) approaches, yet situating them firml

Background: Exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with lower bone mineral content (BMC) and density (BMD) in children, but prospective studies remain limited. We aimed to investigate associations between prenatal and childhood PFAS exposure and BMC/BMD at age 9 years, following up on our previous findings from age 7 years. Methods: We used data from the Odense
This study revives a heavily debated relationship between government debt accumulation and economic growth. Although indebtedness levels stay high, current economic growth forecasts seem optimistic not only in the euro area but in other advanced countries, as well. 24 advanced OECD economies are investigated to understand if financial outcomes are detrimental to the real economic variables in the
Objectives: Menstrual migraine (MM) is a debilitating neurological disorder triggered by fluctuations in ovarian hormones, particularly estrogen. While the calcitonin gene-related peptide (CGRP) system is central to migraine pathophysiology, the molecular mechanisms linking hormonal changes to CGRP signaling remain unclear. This study investigates how sex hormones regulate CGRP-related gene expres
Sweden’s art and music schools (SAMS), established in the 1940s, provideaffordable extra-curricular instrumental and singing teaching for everychild, regardless of their family’s financial situation. Tuition is heavilysubsidised, with families contributing only some 7% of the cost. WhileSAMS traditionally offer one-to-one instruction, a recent governmentalreport (2016) advocates for group teaching
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
Arabinoxylan (AX) with varying arabinose to xylose (A/X) ratios of 0.85, 0.57 and 0.39 was extracted from wheat bran, and the conformations of the AX polysaccharides dispersed in water were investigated using small-angle X-ray scattering. The persistence length (Lp) and the conformation statistics (expressed by the Flory exponent v or the mass fractal) of the AX varied with their A/X ratios. The L
In this paper we suggest that attention to the social practice of prepping, with its particular focus on how people navigate uncertain and potentially disastrous futures, can help broaden our understanding of forced migration. We argue that the emerging literature on doomsday prepping provides a particularly interesting vantage point from which to study the relationship between forced migration, t
Användningen av artificiell intelligens ökar inom många områden i det samtida samhället, inklusive datorsynssystem som bygger på maskininlärning och artificiella neuronnätverk. Dessa system omformar handlingsmöjligheter och beskrivs ofta som ”svarta lådor” som utmanar etablerade former av vetenskaplig förståelse och teknisk kontroll. Det är därför viktigt att förstå de aktiviteter genom vilka sådaThe uses of artificial intelligence are increasing across many areas of contemporary society, including computer vision systems involving machine learning and artificial neural networks. These systems rearrange action possibilities and are often described as “black boxes” that challenge conventional modes of scientific understanding and engineering control. It is important to understand the activi
Biological neural network functionality depends on the vast number of connections between nodes, which can be challenging to implement artificially. One radical solution is to replace physical wiring with broadcasting of signals between the artificial neurons. We explore an implementation of this concept by light emitting/receiving III-V semiconductor nanowire neurons in a quasi-2D waveguide. They
In an era where online interactions increasingly shape social dynamics, the pervasive issue of cyberbullying poses a significant threat to the well-being of individuals, particularly among vulnerable groups. Despite extensive research on text-based cyberbullying detection, the rise of visual content on social media platforms necessitates new approaches to address cyberbullying using images. This d
The Re-Os (rhenium-osmium) chronometer applied to molybdenite (MoS2) is now demonstrated to be remarkably robust, surviving intense deformation and high-grade thermal metamorphism. Successful dating of molybdenite is dependent on proper preparation of the mineral separate and analysis of a critical quantity of molybdenite, unique to each sample, such that recognized spatial decoupling of 187Re par
