Direct Observation of 2DEG States in Shallow Si:Sb δ-Layers

We investigate the electronic structure of high-density layers of Sb dopants in a silicon host, so-called Si:Sb δ-layers. We show that, in spite of the known challenges in producing highly confined Sb δ-layers, sufficient confinement is created such that the lowest conduction band states (Γ states, studied in depth in other silicon δ-layers), become occupied and can be observed using angle-resolve

Adding salt to foods and risk of metabolic dysfunction-associated steatotic liver disease and other chronic liver diseases

PURPOSE: Adding salt to foods, a novel indicator for studying habitual sodium intake, has been positively associated with multiple diseases and mortality. However, little is known about its association with liver-related disorders. This study aimed to investigate the associations of adding salt to foods with risks of metabolic dysfunction-associated steatotic liver disease (MASLD), cirrhosis, and

Theoretical Foundations of the Economics of Slavery : Enslaved People as Capital Investments in the Atlantic World

Despite the prevalence of slavery in world history, our understanding of its persistence remains limited. Most previous studies focus primarily on slavery as a labour contract, indistinguishable from other coercive arrangements such as serfdom. More recent literature on slavery in the United States shows that enslaved people also played an important role as financial instruments. In this article,

The Iran-Israel war, launched on June 13, 2025, marked a historic intelligence failure for the Islamic Republic. Israel’s surprise offensive devastated Iran’s military leadership and exposed deep systemic flaws in its counterintelligence apparatus. The strategic collapse of the regime now raises urgent questions about its survivability and the necessity of regime change.

Is the business of conquest the conquest of business?

This case explores the interplay between commerce and colonial expansion through the lens of the Dutch East India Company (VOC) in the 17th century. Tasked with securing profit while navigating geopolitical rivalries, the VOC’s decision-makers faced dilemmas that blurred the lines between trade and conquest. This case places students in the role of the Heeren XVII, the governing board of the VOC,

Older persons' experiences with wearable sensor-based fall risk screening in free-living conditions - a qualitative study

BACKGROUND: Falls are common among older persons and can have a major impact on their lives. Wearable sensors used in free-living conditions (moving naturally in one's daily living environment) can be used to predict falls and fall risks. To understand if using the wearable sensors is an acceptable way for older persons to be screened for fall risks, it is important to have knowledge of older pers

Considerations in the clinical use of amyloid PET and CSF biomarkers for Alzheimer's disease

Amyloid-β (Aβ) positron emission tomography (PET) imaging and cerebrospinal fluid (CSF) biomarkers are now established tools in the diagnostic workup of patients with Alzheimer's disease (AD), and their use is anticipated to increase with the introduction of new disease-modifying therapies. Although these biomarkers are comparable alternatives in research settings to determine Aβ status, biomarker

A Federated Data Analysis Approach for the Evaluation of Surrogate Endpoints

In clinical trials, surrogate endpoints, that are more cost-effective, occur earlier, or are more frequently measured, are sometimes used to replace costly, late, or rare true endpoints. Regulatory authorities typically require thorough evaluation and validation to accept these surrogate endpoints as reliable substitutes. To this end, the meta-analytic framework is considered a very viable approac

Minimum inhibitory concentration distribution of Mecillinam in clinical Staphylococcus saprophyticus isolates from Europe

Objectives: Staphylococcus saprophyticus (S. saprophyticus) is the second most common bacteria causing uncomplicated urinary tract infections (UTIs). It is considered non-susceptible to mecillinam, with no defined breakpoint and only few available minimal inhibitory concentration (MIC) observations. However, this consideration does not correlate with clinical outcome. With this study, we aimed to

Home Mechanical Ventilation and Risk of Hospitalization in Obesity Hypoventilation Syndrome

Rationale: Patients with obesity hypoventilation syndrome (OHS) have high risk of hospitalization, which might be decreased by home mechanical ventilation (HMV). Objectives: To evaluate annualized hospitalization rate (AHR) and changes in AHR in patients with OHS starting HMV and explore if there were any differences in AHR by starting HMV acutely or electively. Methods: This was a population-base

V-CARE (Virtual Care After REsuscitation): Protocol for a Randomized Feasibility Study of a Virtual Psychoeducational Intervention After Cardiac Arrest—A STEPCARE Sub-Study

Background: Out-of-hospital cardiac arrest (OHCA) survivors and their relatives may face challenges following hospital discharge, relating to mood, cognition, and returning to normal day-to-day activities. Identified research gaps include a lack of knowledge around what type of intervention is needed to best navigate recovery. In this study, we investigate the feasibility and patient acceptabilityBackground: Out-of-hospital cardiac arrest (OHCA) survivors and their relatives may face challenges following hospital discharge, relating to mood, cognition, and returning to normal day-to-day activities.

Validation of a breast cancer assay for radiotherapy omission : an individual participant data meta-analysis

Background: There are currently no molecular tests to identify individual breast cancers where radiotherapy (RT) offers no benefit. Profile for the Omission of Local Adjuvant Radiotherapy (POLAR) is a 16-gene molecular signature developed to identify low-risk cancers where RT will not further reduce recurrence rates. Methods: An individual participant data meta-analysis was performed in 623 patien

Rat Model of Endogenous and Exogenous Hyperammonaemia Induced by Different Diets

Two different diets able to induce dietary hyperammonaemia (a methionine–choline-deficient (MCD) diet and a methionine-deficient diet enriched with ammonium acetate (MAD + 20% ammonium acetate)) were tested in a rat model. The diets were shown to have different modes of action, inducing significant hyperammonaemia (HA) and growth retardation in the rats, with different metabolic consequences. The

Cooperative and competitive effects in pH-dependent surface composition of atmospherically relevant organic ions in water

The molecular surface compositions of aerosols can differ considerably from their bulk counterparts, an aspect often overlooked in climate models. This oversight can potentially affect our understanding of the complex interplay between composition, optical characteristics, and their influence on cloud formation and properties. A substantial portion of aerosol mass often includes organic compounds,
