Analysis of signals defined on complex topologies modeled by graphs is a topic of increasing interest. Signal decomposition plays a crucial role in the representation and processing of such information, in particular, to process graph signals based on notions of scale (e.g., coarse to fine). The graph spectrum is more irregular than for conventional domains; i.e., it is influenced by graph topolog
Mitochondrial diseases are clinically and genetically heterogeneous, often complicating diagnosis. Here, we describe four unrelated individuals with suspected mitochondrial disease who shared similar neuroimaging features, including bilateral symmetrical supra- and infratentorial white-matter abnormalities, together with variable movement disorders and intellectual impairment. Whole-genome sequenc
Introduction: In aortic valve disease, several interventions are available. In young people who are still growing, or considering the risks of long-term anticoagulation, the Ross procedure remains an alternative for aortic valve replacement. This procedure entails the transposition of the patient’s pulmonary valve to the aortic position, with placement of a homograft in the pulmonary position. How
Purpose of review – Oxygen therapy is a key component of interstitial lung disease (ILD) management. This review summarizes the current evidence and explores how to balance its benefits and burdens in people with ILD. Recent findings – Hypoxemia frequently occurs in ILD and is associated with worse prognosis, but the extent to which oxygen therapy modifies outcomes remains uncertain. Observational
In this study, we report the suppression of degradative transformations observed in Na-ion batteries by utilizing five different transition-metal cations at a single crystallographic site, which is expected to impart entropy-induced stabilization, resulting in enhanced structural stability. We successfully synthesized phase-pure O3-NaTi0.2Mn0.2Fe0.2Ni0.2Co0.2O2 through a facile solid-state sinteri
Background and study aims: Barrett’s esophagus (BE) surveillance relies on endoscopy, which can limit accessibility and strain healthcare resources, a challenge in Nordic countries. Non-endoscopic alternatives could improve surveillance efficiency, but implementation data are limited. We assessed the feasibility of implementing EndoSign®, a novel capsule sponge, in Sweden. Patients and methods: Th
Avian blood parasites are vector-transmitted protozoan parasites and common in wild birds. They cause acute and chronic infections at different life stages with potentially detrimental effects on host fitness. Transmission often happens during the nestling period, when biting dipterans have easy access to featherless skin. However, little is known about patterns of infection within and between bro
This article examines the intellectual engagement between the Catholic scholar Ernesto Buonaiuti (1881-1946) - one of the foremost proponents of the historical-critical method in Italy - and the prominent German Protestant church historian Adolf von Harnack (1851-1930). This study adopts a transnational and transconfessional approach to church history, according to which religious thought develops
Ice I is the most abundant crystalline phase of water and plays a fundamental role in nature. Understanding its complex nuclear dynamics is crucial on its own and also provides critical insights into hydrogen bonding networks as well as water’s unique properties. Here, we present high-resolution oxygen K-edge resonant inelastic X-ray scattering (RIXS) of Ice I (H2O and D2O) measured using intense
Surface nitridation induced by ammonia combustion can alter material properties, reducing lifetime and performance of a practical combustor. Although ammonia-induced surface nitriding has been studied at low and moderate temperatures, its behavior at temperatures above 1200 K in flames remains unexplored. This study investigates high-temperature nitriding and the impact of NH radical of nickel rod
This book explores how functional stupidity – uncritical and unreflective thinking within prescribed, constrained ways – is institutionalized and why we should minimize it in workplaces. How did our organizations become stagnant, and what can be done to revive them? Contemporary societal and organizational noise, extensive bureaucratization, silo thinking, imitation, bullshit talk, and meaningless
Introduction: Current international (FIGO) and Swedish cardiotocography (CTG) interpretation templates exhibit limited diagnostic accuracy for the detection of fetal acidemia. The objective of this study was to develop a novel intrapartum CTG classification template incorporating CTG parameters demonstrated to be strongly associated with acidemia, and to evaluate the diagnostic performance of the
Many vibration signals produced by rotating machines have been shown to be second-order cyclostationary. This means that the spectral correlation function can be used to identify cyclic frequencies associated with e.g. faulty machine parts. However, due to spectral leakage, the spectral correlation function often has poor localization of signal components, leading to sub-par fault detection. Recen
Ensamhet och social isolering är utbredda globala samhällsutmaningar, där ungefär en av sex personer världen över uppger att de upplever ensamhet (World Health Organization, 2025a). Psykosocial rehabilitering (PSR), inklusive deltagande i Fontänhusets aktiviteter, kan skapa möjligheter att stärka social gemenskap och delaktighet. Ett Fontänhus är en verksamhet för PSR som bygger på FontänhusmodellLoneliness and social isolation are widespread global challenges, with approximately one in six people worldwide reporting loneliness (World Health Organization, 2025a). Psychosocial rehabilitation (PSR), including participation in Clubhouse activities, may provide opportunities to strengthen social connection and participation. A Clubhouse is a PSR setting based on the Clubhouse Model, which emph
Den svenska förvaltningsmodellen har historiskt sett präglats av en hög grad av social och institutionell tillit. I dagens samhällskontext utgör emellertid denna tillitskultur, i kombination med Sveriges omfattande välfärdssystem, en strukturell sårbarhet. Kriminella nätverk utnyttjar i allt högre grad denna öppenhet för att infiltrera den offentliga förvaltningen inifrån. En central del av denna The Swedish model of public administration has historically been defined by a high degree of social and institutional trust. In the contemporary context, however, this culture of trust, combined with Sweden’s extensive welfare systems, constitutes a structural vulnerability. In recent years, criminal networks have increasingly exploited this openness to infiltrate public administration from within
När myndigheter ska meddela beslut utgör delgivningsprocessen en grundsten i rättssäkerheten i svensk rätt. Den säkerställer möjligheten för den enskilde att få kännedom om myndighetens ingripande och ger denna en möjlighet att utöva sin rätt att överklaga. I huvudregel innebär delgivningen att personen blir medveten om beslutet. Lagstiftningen kräver dock inte att personen läser genom handlingen When public authorities are required to communicate decisions the service of process constitutes a cornerstone of legal certainty within the Swedish legal system. It ensures the individual's opportunity to become aware of the authority's intervention and allows them to exercise their right to appeal. As a rule, service of process means that the person becomes aware of the decision. However
This master’s thesis seeks to examine the legal framework that governs auto-mated decision-making and artificial intelligence within Swedish public ad-ministration. The thesis does so mainly by analyzing the interplay between the GDPR and the EU:s AI Act and relevant Swedish administrative law. Subsequently, the thesis seeks to evaluate the legal conditions for deployment of automated decision-ma
Denna fallstudie av en högstadieskola, syftar att studera och jämföra de faktorer som elever i årskurs nio och deras lärare anser vara av vikt för sin motivation att respektive lära och lära ut ämnet moderna språk. Då Skolinspektionen (2010, 2022) konstaterat att ämnet är föremål för långvariga utmaningar, samtidigt som vi i dagens globala värld har fler kontakter över språkgränserna än någonsin,
