We combine existing perturbative results to show that a precise analytic determination of the charm-quark contribution to the hadronic light-by-light (HLbL) part of the muon anomalous magnetic moment is possible. Working in the MS‾ scheme, we include the NLO O(αs) correction, which significantly reduces the residual renormalization-scale dependence and the perturbative uncertainty. Our final resul
Unseen Sights: Magic, Modernity, and Childhood in Children’s Urban Fantasy explores and analyses the genre of children’s urban fantasy. Drawing upon a combination of fantasy, urban fantasy, and children’s literature scholarship, the thesis considers how children’s urban fantasy works – investigating both its forms and functions, and how it performs work in the world.The genre is analysed both sync
Objectives To examine the associations between socioeconomic position (SEP) and the incidence of serious hand infections—pyogenic flexor tenosynovitis (PFT) and septic arthritis (SA)—as well as risks of opioid overuse following diagnosis using nation-level data. Design In a registry-based nationwide retrospective cohort study, (1) associations between SEP and incidence of PFT/SA; (2) SEP and infec
BACKGROUND: Cardiovascular calcification is a significant predictor and contributor to cardiovascular diseases. Vascular smooth muscle cell (SMC)-derived extracellular vesicles (EVs) play a crucial role in microcalcification formation. EVs can originate from the endosomal system, and PIKFYVE (1-phosphatidylinositol 3-phosphate 5-kinase), a lipid kinase, plays a key role in endomembrane maturation.
Background There is a lack of contemporary data describing patients with left ventricular (LV) systolic dysfunction post myocardial infarction (MI) in terms of symptom burden and secondary prevention measures. The aim of this study was to describe patients with various degrees of LV systolic dysfunction after a first MI, their symptom burden, quality of life and adherence to recommended secondary
Visual assessment of medial temporal lobe atrophy (MTA) in the clinical workup of cognitive impairment is traditionally corrected for age since MTA increases with age. In addition, common pathologies in the elderly such as amyloid, tau, alpha-synuclein and TDP-43 accumulation as well as white matter hyperintensities representing small vessel disease may affect the association between MTA and age.
Introduction: Most centers treating patients with anorectal malformation (ARM) will screen for anomalies of the kidneys and urinary tract by using ultrasonography. There is no consensus on whether screening for vesico-ureteral reflux (VUR) should occur. To meet the diagnostic needs of ARM patients a method was developed to include a simultaneous VUR diagnosis and pre-reconstructive fistula work-up
The transformation of CO2 and green hydrogen into methanol presents a sustainable route for chemical and fuel production. Conventional methanol synthesis catalysts, such as Cu/ZnO/Al2O3, employ Al2O3 as a structural promoter, while Ga2O3 has recently emerged as a promising alternative. This study compares Cu-based catalysts supported on Al2O3 (CA) and Ga2O3 (CG), prepared via coprecipitation of la
Despite rapid advances in mapping genetic drivers and gene expression changes in hematopoietic stem cells (HSCs), few studies exist at the protein level. We perform a deep, multi-omics characterization (epigenome, transcriptome, and proteome) of HSCs in a mouse model carrying a loss-of-function mutation in Tet2, a driver of increased self-renewal in blood cancers. Using state-of-the-art, multiplex
We investigate the influence of AlN buffer thickness on the structural, electrical, and thermal properties of AlGaN/GaN high-electron mobility transistors (HEMTs) grown on semi-insulating SiC substrates by metal-organic chemical vapor deposition. X-ray diffraction and atomic force microscopy reveal that while thin AlN layers (120 nm) exhibit compressive strain and smooth step-flow surfaces, thicke
PURPOSE: The incidence of colorectal cancer (CRC) is increasing in individuals aged < 50 years of age. This study aimed to examine whether high-frequency follow-up after CRC surgery reduces 5-year overall mortality, cancer-specific mortality and recurrence in patients with CRC aged ≤ 50 years. METHODS: The COLOFOL trial performed between 2006 and 2010 was used to analyse patients randomised to hig
Action-detected two-dimensional electronic spectroscopy (A-2DES) provides valuable insights into ultrafast dynamics within functional materials and devices by measuring incoherent signals like photocurrent. This work details the implementation and optimization of a pulse-shaper-based A-2DES setup, focusing on methodological strategies crucial for acquiring high-fidelity data. We present a comprehe
The development of acid-stable, non-precious catalysts for the oxygen evolution reaction (OER) remains a critical challenge for proton exchange membrane water electrolyzers (PEMWEs). While Co3O4 shows promising OER activity, its rapid dissolution in acidic media severely limits practical application. Here, we design a self-adaptive protection strategy by depositing ZrN coatings on Co3O4 precursor
Protein tyrosine phosphatases (PTPs) are a family of enzymes that play important roles in regulating cellular signaling pathways. The activity of these enzymes is regulated by the motion of a catalytic loop that places a critical conserved aspartic acid side chain into the active site for acid–base catalysis upon loop closure. These enzymes also have a conserved phosphate-binding loop that is typi
Atomic layer deposition (ALD) of HfOx layers has emerged as a promising strategy for interface passivation in chalcopyrite-based thin-film solar cells. However, the nucleation dynamics of (Ag,Cu)(In,Ga)Se2 (ACIGS) absorbers remain insufficiently understood, particularly regarding the interplay between absorber composition and alkali postdeposition treatments (PDTs). Here, we employ in situ ambient
