Darknet framställs ofta som en digital värld präglad av avvikelse och kriminalitet – en plats där ”allt är tillåtet” och som därför anses kräva övervakning och kontroll. Trots detta är kryptoforum fortfarande relativt understuderade. Med utgångspunkt i tre års etnografiskt fältarbete ger denna avhandling nya insikter i de interna dynamikerna i en till stor del dold onlinegemenskap. Genom att kombiThe Darknet is often portrayed as an online realm marked by deviance and criminality – a space where “anything goes” and therefore requires policing. Yet its cryptoforums remain comparatively understudied. Drawing on three years of ethnographic fieldwork, this dissertation provides new insights into the internal dynamics of a largely hidden online community. Combining digital observations with 19

Infective endocarditis (IE) is most often caused by alpha-hemolytic streptococci or Staphylococcus aureus and is characterized by the presence of vegetations on the heart valves. Here we present a case of IE caused by Streptococcus pyogenes, a distinctly uncommon IE-pathogen, where no vegetations could be visualized on repeated echocardiography. Diagnosis was instead evident from septic embolizati

OBJECTIVES: Nociception monitoring during general anesthesia is evolving to improve intraoperative management and postoperative outcomes. While opioid-based anesthesia (OBA) remains widely used for its strong antinociceptive effects, concerns about opioid-induced adverse effects have fueled interest in opioid-free anesthesia (OFA) approaches. This study aimed to compare perioperative and postopera

In 2022 and 2023, the Large Hadron Collider produced approximately two billion hadronic interactions each second from bunches of protons that collide at a rate of 40 MHz. The ATLAS trigger system is used to reduce this rate to a few kHz for recording. Selections based on hadronic jets, their energy, and event topology reduce the rate to Ô(10) kHz while maintaining high efficiencies for important s

ALICE is a large experiment at the CERN Large Hadron Collider. Located 52 meters underground, its detectors are suitable to measure muons produced by cosmic-ray interactions in the atmosphere. In this paper, the studies of the cosmic muons registered by ALICE during Run 2 (2015–2018) are described. The analysis is limited to multimuon events defined as events with more than four detected muons (Nµ

INTRODUCTION: Health promotion in everyday settings is of great importance for both individual health and organizational sustainability. A settings-based approach emphasizes how social, physical, and organizational contexts shape the conditions for health. Central principles in health promotion are participation, empowerment, and person-centeredness, which emphasize the active role of the person o

This paper explores the rapid digitalization of the economy, focusing on the rise of platform and influencer economies, and examines their impact on place branding and clusters within rural regional development. Our study demonstrates how influencers in a rural industrial cluster become key figures in regional place branding by merging their digital identities with the natural resources they promo

The European spallation source (ESS) will be the world’s brightest neutron source and will open a new intensity frontier in particle physics. The HIBEAM collaboration aims to exploit the unique potential of the ESS with a dedicated ESS instrument for particle physics which offers world-leading capability in a number of areas. The HIBEAM program includes the first search in thirty years for free ne

Objectives: Sjögren's disease (SjD) and systemic lupus erythematosus (SLE) share genetic risk at the DDX6-CXCR5 locus (11q23.3). Identifying and functionally characterising shared SNPs spanning this locus can provide new insights into common genetic mechanisms of autoimmunity. Methods: Transdisease meta-analyses, fine-mapping, and bioinformatic analyses prioritised shared likely functional single

The years 2023 and 2024 were characterized by unprecedented warming across the globe, underscoring the urgency of climate action. Robust science advice for decision makers on subjects as complex as climate change requires deep cross- and interdisciplinary understanding. However, navigating the ever-expanding and diverse peer-reviewed literature on climate change is enormously challenging for indiv

This paper presents a measurement of jet-track correlations in photon-jet events, using 1.72 (Formula presented) of (Formula presented) data at (Formula presented) recorded with the ATLAS detector at the LHC. Events with energetic photon-jet pairs are selected, where the photon and jet are approximately back-to-back in azimuth. The angular correlation between jets and charged-particle tracks with

Importance: While clinical disease stages remained largely unchanged in the 2024 update of the Alzheimer disease (AD) criteria, tau-positron emission tomography (PET) was introduced as a core biomarker and its spatial extent was incorporated into the revised biological stages of the disease. It is important to consider both the clinical and the biological stages and understand their discrepancies.

During the 2015–2018 data-taking period, the Large Hadron Collider delivered proton-proton bunch crossings at a centre-of-mass energy of 13 TeV to the ATLAS experiment at a rate of roughly 30 MHz, where each bunch crossing contained an average of 34 independent inelastic proton-proton collisions. The ATLAS trigger system selected roughly 1 kHz of these bunch crossings to be recorded to disk. Offli

Recovery Colleges (RCs) are learning-based mental health recovery communities, located globally. However, evidence on RC effectiveness outside Western, educated, industrialised, rich, and democratic (WEIRD) countries is limited. This study aimed to evaluate associations between cultural characteristics and RC fidelity, to understand how culture impacts RC operation. Service managers from 169 RCs s

Congenital anomalies of the kidneys and urinary tract (CAKUT) are developmental disorders that commonly cause pediatric chronic kidney disease and mortality. We examine here rare coding variants in 248 CAKUT trios and 1742 singleton CAKUT cases and compare them to 22,258 controls. Diagnostic and candidate diagnostic variants are detected in 14.1% of cases. We find a significant enrichment of rare

We show exponential lower bounds on resolution proof length for pigeonhole principle (PHP) formulas and perfect matching formulas over highly unbalanced, sparse expander graphs, thus answering the challenge to establish strong lower bounds in the regime between balanced constant-degree expanders as in [Ben-Sasson and Wigderson’01] and highly unbalanced, dense graphs as in [Raz’04] and [Razborov’03

Objective: Establishing the incidence and types of complications following surgical intervention for ARM, primarily after reconstruction. Patient- and treatment-related risk factors were also determined. Background: Postoperative complications of ARM surgery vary widely, with data predominantly derived from single-center retrospective studies with limited number of patients. Whether factors such a

Det övergripande syftet med denna studie är att finna strategier för att skapa ett friskare arbetsliv långt upp i åren och för att se äldre medarbetare som en viktig resurs vilket organisationen bör värna om och förvalta. I denna rapport studeras enkätsvaren från cirka 2 000 medarbetare 55 år eller äldre inom hälso- och sjukvården. De svarande kom från yrkesgrupperna läkare, sjuksköterska, sjukgym
