This thesis is focused on the investigation of the ultrafast structural response of the phase change material (PCM) Ge$_2$Sb$_2$Te$_5$ following laser excitation. Phase change materials are a group of materials capable of rapid, non-volatile, switching between an amorphous and a crystalline phase. The two phases exhibit high optical and electrical contrast, meaning the optical reflectivity and the

Kulturarv har blivit en alltmer politiserad fråga och väcker debatt om tillhörighet, inkludering och identitet, inte minst i relation till nationen. Samtidigt betonas kulturarvens betydelse i frågor som rör lärande, digitalisering, tillväxt, innovation och hållbarhet.I denna antologi undersöker författarna samspelet mellan kulturarvspedagogik och politik inom olika delar av kulturarvssektorn – sås

BACKGROUND: Catheterization of the vein is frequently a painful procedure. Assessing venous cannulation induced pain (VCP) before surgery have been used to predict the intensity of postoperative pain and postoperative opioid consumption. The aim of this study was to investigate the intra-individual variation in venous cannulation induced pain at three consecutive time points and factors influencin

Understanding the drivers of diversity and change in regional Neolithization trajectories has emerged as a major theme in World Prehistory with new insights appearing in many parts of the globe. In Northeast Asia, research on Neolithic transition over the past two decades has focused primarily on millet and rice domestication and their role in the rise of farming, social complexity, and early Chin

Avhandlingen undersöker föreningar i Sverige som organiserar öppna verkstäder. Öppna verkstäder, vilka också kallas för makerspaces, är platser som möjliggör skapande. Verktyg, maskiner och kunskap är delade mellan användarna. Syftet med avhandlingen är att undersöka hur föreningar organiserar sina delade verkstäder, vilka svårigheter föreningarna möter samt vilka implikationer detta har för den bAlternative building as an interstitial mode of transformation plays a central role in the discussion of strategies for degrowth. In this debate the questions of how alternative projects can be scaled up and how degrowth politics can gain broad societal support have been identified as crucial. In this context open workshops – grassroots infrastructures for creative activities, such as repair, upcy

Aim: In uncertain clinical situations, such as assessing the risk of exacerbation of apical periodontitis in root-­ filled teeth, un-dergraduate students can benefit from being trained to reflect. This study aimed to explore how students specifically reflectedon clinical experiences in relation to uncertainty when assessing a case involving a root-­ filled tooth with apical periodontitis.Methodolo

To secure sufficient, clean, and reliable drinking water amidst climate change, evolving land use, and population growth, artificial infiltration ponds are essential tools for drinking water providers in many areas. Optimizing their operation requires a detailed understanding of infiltration processes and subsurface water transport dynamics.At a Managed Aquifer Recharge (MAR) facility in southern

Introduction: Qualitative assessment of hypoxic ischaemic encephalopathy on computed tomography (CT) after cardiac arrest is limited by interrater agreement. We explored how qualitative assessment can be improved. Methods: In-depth analysis of radiological items evaluated in a prospective sub-study within the Targeted Hypothermia versus Targeted Normothermia after out-of-hospital cardiac arrest (T

The model is based on an existing framework for high-cycle fatigue by Ottosen et al. (2008) that treats the fatigue damage as a time-continuous variable, opposed to relying on cycle-counting techniques. We propose a generalized formulation where the relationship between the fatigue limits for fully reversed shear stress and normal stress can take any value, unlike in the original formulation, wher

The dispersive approach to the hadronic light-by-light contribution to the muon g − 2 involves an integral over three virtual photon momenta appearing in the light-by-light tensor. Building upon previous works, we systematically derive short-distance constraints in the region where two momenta are large compared to the third, the so-called Melnikov-Vainshtein or corner region. We include gluonic c

We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, aμ, updating the first White Paper (WP20) [1]. The pure QED and electroweak contributions have been further consolidated, while hadronic contributions continue to be responsible for the bulk of the uncertainty of the SM prediction. Significant progress has been achieved in the hadronic light-by-light scat

In recent years, unbalanced diets and high consumption of processed foods have primarily contributed to the rise of diet-related diseases, such as obesity and diabetes, among others. One way to address these problems is to increase the consumption of plant-based foods rich in fibre, healthy fats, and protein. The growing interest in plant-based foods continues to rise, leading to a rapid expansion

Each year as the seasons turn, the skies fill with millions of travellers. From the tundra to the tropics, birds embark on remarkable journeys guided by an innate programme and perform one of nature’s most remarkable phenomena: migration. In this thesis, I tackle the study of the genetic basis of migratory behaviour in several Phylloscopus species with a multimodal approach. Here, I combine geoloc

This paper presents the first online, in-situ experimental evidence of the puffing behavior of aluminium (Al) atoms during the ignition of a micron-sized Al wire. As the protective alumina (Al2O3) layer ruptures, spatially resolved laser absorption measurements reveal the outward puffing of Al atoms from the molten Al wire core. These Al atoms then react with the surrounding oxidizers, leading to

The fast development of generative artificial intelligence (“AI”) services—such as ChatGPT, Midjourney, Dall-E—have within a short period of time gained immense uptake and popularity. At the same time, such services have given rise to fundamental challenges from a copyright perspective. Court proceedings have been initiated in many jurisdictions on the compatibility of such services with copyright

The European Society for Clinical Evaluation of Balance Disorders (ESCEBD), based in Nancy, France, has been meeting yearly since 2005 to discuss equilibrium-related themes that are not yet clearly defined or standardized. One of our latest discussions was with regard to outlining strategies of internal and external compensation that may be used to cope with balance disorders. A Committee was elec
