Laser wakefield accelerators produce ultrashort, highly relativistic electron and x-ray pulses in plasma over millimeter distances. Crucial for investigations and applications of these pulses is a reproducible and controlled output beam pointing. Even with a perfectly stable laser, pulse-front tilt in the driving laser pulse has been shown to cause both the laser pulse and the electron beam to dev
Group exhibition.The exhibition will present works by Danish and international artists who in a variety of ways use photography or other camera-based media in their practice to investigate, illuminate, contest or challenge photography's status as document, truth or evidence - materially as well as thematically and culturally.
Dopaminergic neurons in the ventral midbrain are critical for regulating movement, cognition, and emotion. Ventral midbrain organoids can be used to model both development and diseases of the dopaminergic system, especially Parkinson’s disease. Here, we summarize recent advances and remaining challenges in developing such three-dimensional organoids from human pluripotent stem cells. We outline ho
Hand eczema and facial skin problems are common occupational-related skin diseases. However, the data regarding care workers in community care settings are limited. To assess the prevalence and factors associated with hand eczema and facial skin problems among community care personnel, an online questionnaire link was sent to 10,194 personnel in Sweden, with questions regarding hygiene routines, s
The development of bioactive peptides is of great interest in the food and pharmaceutical industries because of their positive impact on health. However, peptide's bioavailability depends on their stability along the gastrointestinal tract and their ability to be transported to targets located in peripheral organs, whose mechanisms are still poorly understood. However, several studies, mainly in v
Asthma is a common health problem. Both common and rare genetic risk factors may contribute to asthma, but few large-scale whole-exome sequencing studies elucidating the contribution of rare variations to asthma have been published. Two published UK Biobank portals: the Genebass portal (N = 269,171) and the Astra Zeneca portal (N = 484,111) (https://azphewas.com/and https://app.genebass.org/) were
The photoelectric effect explained by Einstein is often regarded as a one-electron phenomenon, whereas the interaction of the escaping electron with other electrons, referred to as electron correlation, plays an important role in multielectron systems. In this Letter, we study the attosecond photoionization of the outer s subshell of argon in its substantial minimum cross-section region formed by
Entomological lidar can provide rapid, non-intrusive assessment of insect abundance, diversity and composition, and has the potential to shed light on species specific preferences for habitats or environmental conditions. However, few studies have to date demonstrated comparisons of insect diversity and abundance across sites using photonic methods. Here, we present a first comparative entomologic
Partial-volume effects (PVEs) arise from the limited spatial resolution of PET and SPECT imaging systems, causing the systematic underestimation of activity concentration in structures that may hold critical diagnostic, treatment, or dosimetric information that impacts patient management. Recovery coefficient (RC)-based partial-volume correction (PVC) is one of the simpler approaches used to corre
L-DOPA-induced dyskinesia (LID) is a debilitating complication of dopamine replacement therapy in Parkinson's disease and the most common hyperkinetic disorder of basal ganglia origin. Abnormal activity of striatal D1 and D2 spiny projection neurons (SPNs) is critical for LID, yet the link between SPN activity patterns and specific dyskinetic movements remains unknown. To explore this, we implemen
This master thesis investigates the legal foundations for training of artificial intelligence (AI) models using personal data, with an emphasis on compliance with the European Union’s General Data Protection Regulation (GDPR). The core issue addressed is the lack of clear legal basis for AI training processes that involve the collection and use of personal data (gathered directly or indirectly thr
This thesis examines the Energy Charter Treaty's (ECT) Fair and Equitable Treatment (FET) standard, how it was modernized in 2024, and how this modernization affects the legal position of developing and energy-exporting nations, especially those in the Caspian Sea region. The goal is to determine whether modernization broadens states' regulatory latitude to pursue the energy transition and
Syftet med detta arbete var att undersöka hur data på ett smidigt sätt kan överföras från Excel till en relationsdatabas, samt hur en sådan databas kan användas för att effektivisera processer inom automationsprojekt. Arbetet inleddes med intervjuer för att identifiera vilka delar av automationsprojekten som upplevdes som ineffektiva, samt vilka lösningar som efterfrågades. Därefter inleddes progrThe purpose of this project was to investigate how data can be efficiently transferred from Excel to a relational database, and how such a database can be used to streamline processes within automation projects. The work began with interviews aimed at identifying inefficiencies in current workflows and gathering insights on desired solutions. Based on the findings, the development phase was initia
Parkinson's disease (PD) is characterized by a set of motor symptoms that depend on nigrostriatal dopaminergic degeneration and respond well to pharmacological dopamine replacement using L-DOPA. However, replacing dopamine with either L-DOPA or dopamine receptor agonists leads to the appearance of motor and nonmotor complications within a few years. Strong emphasis is currently placed on developin
l-DOPA-induced dyskinesia (LID) is a prevalent complication of dopamine replacement therapy in Parkinson’s disease. In addition to its clinical importance, LID represents a paradigm to unravel how altered signaling downstream of dopamine receptors can disrupt mechanisms of synaptic plasticity and motor information processing in the cortico-basal ganglia network. This chapter focuses on experimenta
We present memory-based language modeling as an efficient, eco-friendly alternative to deep neural network-based language modeling. It offers log-linearly scalable next-token prediction performance and strong memorization capabilities. Implementing fast approximations of k-nearest neighbor classification, memory-based language modeling leaves a relatively small ecological footprint both in trainin
A meditation on gratitude, strangeness, and listening with careA deceptive cadence suggests resolution but withholds it, opening instead to uncertainty, fragility, and the unexpected. This philosophical-existential inquiry takes that musical figure as a metaphor for life itself—disrupted by illness, sustained by another’s gift, and reshaped by the presence of death. Music here becomes a vital comp
The aim of this study was to perform histopathological reassessment of primary resections of locally advanced colon cancer (CC) within a randomized controlled trial, with specific focus on surgical margins and synchronous locoregional peritoneal metastases (SL-PM), and to provide learning points for both surgeons and pathologists. All histopathological slides of patients with c/pT4N0-2M0 or perfor
BackgroundSome patients scheduled for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) only undergo explorative laparotomy (open/close procedure) due to extensive tumor spread or challenges in achieving complete cytoreduction (CC0). This study aimed to evaluate the surgical outcomes and overall survival in patients with peritoneal surface malignancy (PSM) who only
