This work introduces a sustainable and versatile synthesis platform for nanosized metal–ceria catalysts with tunable composition, directly relevant to renewable energy conversion and CO2 utilization. The method enables parallel preparation of multiple catalysts in a single batch with high yield and reproducibility, while reducing environmental impact by 92% compared to conventional approaches, as

Globular clusters host complex stellar populations whose chemical signatures suggest early (-) retention and reprocessing of stellar ejecta, yet direct evidence for intracluster gas is lacking. Here we present a unified theoretical framework for the evolution of gas in young globular clusters, and its implications for the production of multiple stellar populations. We show that low-velocity AGB wi

Objectives: Mammographically spiculated breast cancer is frequently less aggressive than cancers with alternative appearances. This study aims to investigate whether the degree of spiculations relative to the tumor mass on mammography, termed the spic mass ratio (SMR), is associated with breast cancer characteristics and survival. Materials and methods: This retrospective exploratory single-center

Carbon Fibre-Reinforced Polymers (CFRP) are a fast growing market of high performance materials and components. Thermally induced damage during machining processes such as drilling or routing are among the limiting factors for product quality, yet accurate temperature measurement remains challenging. This study develops a methodology which combines machinable thermocouples and IR thermometry techn

Background: Classification attempts and treatment strategies for endometriosis have been predominantly biomedical. Symptom profiles observed in individuals with endometriosis are multidimensional and may be more effectively captured by a biopsychosocial model. Methods: The aim of this study was to identify distinct subgroups of individuals with endometriosis based on their biopsychosocial profiles

Universities have long used internationalization to prepare students for a highly interconnected world. Although internationalization has often been associated with mobility, current calls for equity, diversity, and inclusion, and climate consciousness, among other things, require institutions to change this strategy. As a response, curriculum internationalization emerges as a more inclusive and s

Background and purpose — Computed tomography (CT) has become a valuable tool for preoperative planning and perioperative, real-time navigation during total hip arthroplasty (THA). CT can also quantify postoperative implant migration without the need for implanted bone markers, making it a promising alternative to the current gold standard radiostereometric analysis (RSA). Our aim was to evaluate t

Downfolding Methods in Many-Electron Theory is a comprehensive description of the last 30 years of study in this field, starting from LDA+U to LDA+DMFT and arriving at the recent work on multitier self-consistent GW+EDMFT. It focuses on different levels of first-principles electronic structure theories for strongly correlated electrons and outlines the downfolding method as a general approach-prov

We present a method to calculate neutron scattering cross sections for deformed nuclei using many-body wave functions described with multiple reference states. Nuclear states are calculated with the generator coordinate method using a low energy effective Hamiltonian. Using these states, a nonlocal and energy dependent optical potential is consistently constructed, allowing one to directly investi

This thesis proposes a multi-step methodology for short-term photovoltaic (PV) power forecasting in regions lacking extensive historical PV generation data, with a case study conducted in Dewathang, Bhutan. As Bhutan’s energy security faces increasing threats from climate change—primarily due to its heavy reliance on hydropower—there is growing national interest in diversifying energy sources, par

BACKGROUND: Patients receiving intraoperative ventilation during general anesthesia often have low end-tidal CO2 (etCO2). We examined the association of intraoperative etCO2 levels with the occurrence of postoperative pulmonary complications (PPCs) in a conveniently-sized international, prospective study named 'Local ASsessment of Ventilatory management during General Anesthesia for Surgery' (LAS

IMPORTANCE: Robot-assisted surgery (RAS) is increasingly used for abdominal procedures; however, postoperative pulmonary complications (PPCs) are more frequent in patients undergoing RAS compared with patients undergoing conventional laparoscopic surgery (CLS).OBJECTIVE: To compare the incidence of PPCs after CLS and RAS and to determine which patient-, surgery-, and anesthesia-related factors are

Inequalities between Dirichlet and Neumann eigenvalues of the Laplacian and of other differential operators have been intensively studied in the past decades. The aim of this paper is to introduce differential forms and the de Rham complex in the study of such inequalities. We show how differential forms lie hidden at the heart of the work of Rohleder on inequalities between Dirichlet and Neumann

Rewetting is widely promoted as a climate mitigation strategy to preserve soil carbon in drained wetlands, although rewetting may enhance methane production and corresponding emissions. The increase in methane emissions following rewetting might be underestimated without considering near-surface methane oxidation under a fluctuating water table. Here, we refined the methane module in Lund-Potsdam-

This review examines how coordination is infrastructured in digital health ecosystems where technologies, institutions, and practices intersect across organisational and professional boundaries. Drawing on a systematic analysis of the literature, we identify three interdependent infrastructural layers: technological, informational, and institutional, and four recurring processes through which coor
