Colorful flower patterns are key signals to attract pollinators. To produce such motifs, plants specify boundaries dividing petals into subdomains where cells develop distinctive pigmentations, shapes, and textures. While some transcription factors and biosynthetic pathways behind these characteristics are well studied, the upstream processes restricting their activities to specific petal regions
Quasi-two dimensional (2D) perovskites have emerged as a promising class of materials due to their remarkable photoluminescence efficiency, which stems from their exceptionally high exciton binding energies. The spatial confinement of excitons within smaller grain sizes could enhance the formation of biexcitons leading to higher radiative recombination efficiency. However, the synthesis of high-qu
Context: Contemporary patients with primary hyperparathyroidism are diagnosed with milder disease than previously. Clinical and biochemical factors predictors with an impact on fracture incidence and bone mineral density after surgery have not been firmly established. Objective: To investigate predictors of fracture incidence and bone mineral density preoperatively and after surgery for primary hy
Ambient pressure X-ray photoelectron spectroscopy is employed to study in real time the chemical reactions occurring on (Ag,Cu)(In,Ga)Se2 (ACIGSe) surfaces during the first atomic layer deposition (ALD) cycle of HfOx under realistic synthesis conditions by using tetrakisdimethylamido-hafnium (TDMA-Hf) and H2O precursors. We find that the initial deposition due to surface reactions of HfOx ALD on A
The present work describes the formation of low-aspect-ratio Ag nanoparticles (NPs) arrays by sequential deposition of Ag from different growth directions on a nanoripple-patterned Si substrate, produced by low-energy ion beam irradiation. It is observed that the growth of Ag-NPs on ripple surfaces is direction-dependent due to the asymmetric ridge of the ripple pattern. This asymmetric ridge can
Nanoplastics are emerging environmental contaminants that increasingly threaten soil ecosystems, yet their effects on microbial behavior remain poorly understood. This is mainly due to the lack of experimental tools capable of directly observing microbial dynamics in situ under realistic soil-like conditions. Here, we present a proof-of-concept system that enables real-time, high-throughput monito
BACKGROUND: Children with autism spectrum disorder (ASD) are at increased risk of epilepsy (EP), but distinguishing epileptic seizures from ASD-associated behavior remains a clinical challenge. Although previous studies have reported changes in peripheral immune markers in adults with EP, it remains unclear whether similar immune signatures are present in pediatric patients with both ASD and EP, a
AIMS: Vascular atherosclerotic calcification is a pathological process marked by the abnormal deposition of calcium minerals in the intima. Asporin (ASPN) is a small leucine-rich proteoglycan which interacts with collagen and calcium. Due to its role in matrix mineralization, we hypothesized that ASPN might act as a regulator of vascular calcification, thereby promoting atherosclerotic plaque stab
Background: Nocturnal hypoxemia commonly affects people with pulmonary fibrosis (PF). Research Question: What are the current practices for assessment of sleep and nocturnal hypoxemia in PF, and what are the research priorities and outcome measures of importance for nocturnal oxygen therapy (NOT)? Study Design and Methods: People with PF and health care professionals (HCPs) with expertise in PF, s
Objective: In the present study, we investigated the role of the gut–liver crosstalk in the pathogenesis of steatotic liver disease (SLD) induced by the compounding and deleterious effects of alcohol and metabolic risk factors, and explored the potential translational aspects of microbiome-based interventions. Design: The effects of combined exposure to alcohol and a high-fat, high-cholesterol die
We investigate so-called Laplace–Carleson embeddings for large exponents. In particular, we extend some results by Jacob, Partington, and Pott. We also discuss some related results for Sobolev-and Besov spaces, and mapping properties of the Fourier transform. These variants of the Hausdorff–Young theorem appear difficult to find in the literature. We conclude the paper with an example related to a
Objectives. To investigate metabolic features that may predispose to GCA in a nested case-control study. Methods. Individuals who developed GCA after inclusion in a population-based health survey (the Malmö Preventive Medicine Project; N ¼ 33 346) were identified and validated through a structured review of medical records. Four controls for every validated case were selected from the database. Re
Aim: To improve consistency between register studies in Sweden and ensure valid comparisons of possible changes in alcohol-related disorders and diseases (ARDDs) over time, we propose a definition of ARDDs. Based on this definition, we examined Sweden’s incidence rates of ARDDs from 1970 to 2018 in non-primary healthcare settings (inpatient and outpatient). Methods: Swedish Society of Epidemiology
Packed beds with methane steam reforming reaction (MSR) can be used as thermochemical storage devices. The packing configuration can have a significant effect on the flow distribution which will further influence the heat/mass transfer, dispersion and reaction characteristics. In the present paper, the hydraulic, dispersion, heat/mass transfer and the MSR reaction properties are investigated in pa
Objectives: To study how radiologists’ perceived ability to interpret digital mammography (DM) images is affected by decreases in image quality. Methods: One view from 45 DM cases (including 30 cancers) was degraded to six levels each of two acquisition-related issues (lower spatial resolution and increased quantum noise) and three post-processing-related issues (lower and higher contrast and incr
