The Majorana tetron is a prototypical topological qubit stemming from the ground-state degeneracy of a superconducting island hosting four Majorana modes. This degeneracy manifests as an effective nonlocal spin degree of freedom, the most paradigmatic signature of which is the topological Kondo effect. Degeneracies of states with different fermionic parities also characterize minimal Kitaev chains

Quantum instruments describe both the classical outcome and the updated state associated with a quantum measurement. We ask whether these processes can be simulated using only a natural subset of resources, namely projective measurements on the system and quantum processing of the postmeasurement states. We show that the simulability of instruments can be connected to an entanglement classificatio

This study presents the fabrication of all-dielectric silicon-based twisted L-shape metamaterials using a two-step electron-beam glancing angle deposition approach. Systematic chiroptical characterization and optimization are performed through Mueller matrix generalized spectroscopic ellipsometry and finite element modeling, demonstrating tunable, broadband chirality response with potential applic

Tuning the spectral and directional characteristics of thermal emission is critical for advancing technologies such as thermophotovoltaics (TPVs), passive thermal radiative cooling (PTRC), and solar thermophotovoltaics (STPVs), yet scalable fabrication methods remain limited. Here, femtosecond laser surface processing (FLSP), a top-down ablation and re-solidification approach is employed, to creat

Introduction: Myocarditis is a complex cardiac disorder with multifactorial etiology, characterized by myocardial inflammation, cardiomyocyte damage, and fibrosis. Left untreated, myocarditis may lead to acute and chronic heart failure and life-threatening arrhythmias. Reliable experimental models of myocarditis are required to study the underlying pathological mechanisms of the disease and to dev

The concept of scattering contrast is central to (small-angle) scattering of neutrons, X-rays, and visible light, as it defines the visibility to the radiation of the nano- and mesostructures under scrutiny, in their respective solvent or matrix. In this chapter, we start with the scattering process by elementary scatterers, such as nuclei or atoms, which produce secondary, scattered waves, and th

Cardiovascular disease (CVD) is the leading cause of death in Europe, with myocardial infarction (MI) being one of its most severe manifestations. While many risk factors for CVD are well known, occupational exposures remain relatively understudied—especially in analyses that adjust for co-occurring workplace exposures. This study aimed to examine the association between occupational exposure to c

Background: Paleolithic Diet Fraction (PDF) and Paleolithic Diet Score (PDS) are both measures of how closely a food intake conforms to a Paleolithic dietary pattern. PDF is calculated directly from an individual’s absolute food intake and PDS is an aggregated score based on an individual’s food intake relative to a population. Both are inversely associated with all-cause and cause-specific mortal

Peripheral nerve tumours, most commonly schwannomas and neurofibromas, might present significant challenges by eliciting physical symptoms and emotional distress. We aimed to explore patients’ expectations, perceptions, and experiences regarding their diagnosis and the surgical treatment of a nerve tumour in the upper limb. Fourteen adults (10 women, 4 men; age range 35–85) from two Swedish hand s

Objective: Drug-coated balloons (DCB) might improve the results of below the knee (BTK) angioplasty, but sufficient randomized data comparing DCB and conventional angioplasty in treating patients with chronic limb threatening ischemia (CLTI) are lacking. This study aimed to perform a randomized comparison between a paclitaxel-coated angioplasty balloon catheter and a conventional balloon angioplas

Air pollution is increasingly discussed as a risk factor for dementia, but the biological mechanisms are not yet fully understood. Biological markers like telomere length are relevant to study with air pollution, as they are associated with aging and dementia. The study aimed to investigate the relationship between source-specific air pollution exposure and telomere length in a low-level air pollu

This thesis presents four interconnected studies showing methods for characterizing and separating cells based on their acoustic properties, with particular focus on isolating rare cells from blood samples.The first study introduces a technique for single-cell density measurements using microcapillary-adapted density gradient centrifugation. Using fluorescent markers to visualize the density gradi

Entanglement has the ability to enhance the transmission of classical information over a quantum channel. However, fully harvesting this advantage typically requires complex entangling measurements, which are challenging to implement and scale with the system's size. In this Letter, we consider a natural quantum information primitive known as a random access code in which the message to be communi

Introduction: Prenatal exposure to inflammatory states has been suggested to influence offspring neurodevelopment. The aim was to investigate if offspring exposure to maternal Inflammatory bowel disorder (IBD), or specifically the IBD disorder Crohn's disease, during gestation is associated with neurodevelopmental or psychiatric disorders in childhood. Material and Methods: We conducted a populati

Symmetric informationally complete measurements are both important building blocks in many quantum information protocols and the seminal example of a generalized, non-orthogonal, and quantum measurement. In higher-dimensional systems, these measurements become both increasingly interesting and increasingly complex to implement. Here, we demonstrate an integrated quantum photonic platform, operatin

Objective To evaluate any association of the presence and severity of nine major symptoms (pain, tiredness, drowsiness, nausea, appetite, breathlessness, depression, anxiety, and perceived well-being) with sleep quality and duration in elderly men.Design and setting Cross-sectional analysis within the population-based VAScular and Chronic Obstructive Lung disease study (VASCOL) conducted in southe

Halide perovskite solar cells (PSCs) have emerged as a transformative photovoltaic technology, achieving unprecedented power conversion efficiencies. However, the development of electron-transport materials (ETMs), particularly organic ETMs, has significantly trailed behind the rapid progress in hole-transport materials (HTMs). Among the organic ETMs, naphthalene diimide (NDI)-based systems stand

This study examines the relationship between income-related health inequality (IRHI) and macroeconomic conditions. We complement an income group-based analysis of the impact of macroeconomic conditions on mortality by incorporating an analysis of the concentration index as a comprehensive measure of overall IRHI. Using a recentered influence function regression approach, we estimate the impact of

Stage- and lineage-specific gene expression patterns are controlled by a complex interplay between transcription factors, the epigenetic landscape, and the three-dimensional (3D) structure of the DNA. The 3D structure allows for the formation of DNA loops that juxtaposition distal regulatory elements to the promoters, allowing for tight control of gene expression. Developing a tool to facilitate t

Acoustofluidic particle manipulation has attracted considerable interest in biomedical applications due to its non-contact and label-free characteristics. However, existing computational models for predicting particle motion in acoustofluidic systems mainly focus on single-particle behavior, often neglecting particle–particle interactions and the impact of particle distribution on the acoustic and
