Article Abstract
Kinetic Monte Carlo (KMC) is an efficient method for studying diffusion. A limiting factor to the accuracy of KMC is the number of different migration events allowed in the simulation. Each event requires its own migration energy barrier. The calculation of these barriers may be unfeasibly expensive. In this article we present a data set of migration barriers on for nearest-neighbour jumps on the Cu surfaces, calculated with the nudged elastic band (NEB) method and the tethering force approach. We used the data to train artificial neural networks (ANN) in order to predict the migration barriers for arbitrary nearest-neighbour Cu jumps. The trained ANNs are also included in the article. The data is hosted by the CSC IDA storage service.
Gliomas are the most common tumors of the central nervous system, with glioblastoma (GBM) being particularly aggressive and fatal. Current treatments for GBM, including surgery and chemotherapy, are limited by tumor aggressiveness and the blood-brain barrier. Therefore, understanding the molecular mechanisms driving GBM growth is essential.
Aqueous zinc-ion batteries (AZIBs) are considered a promising choice for energy storage devices owing to the excellent safety and favorable capacity of the Zn anode. However, the uncontrolled dendrite growth of Zn anode severely constrains the practical applications of AZIBs. Herein, a novel ion enrichment layer of CuS is designed and constructed on the Zn foil surface to achieve dendrite-free Zn anode.
Unlabelled: are facultative intracellular bacterial pathogens that cause foodborne disease in humans. The bacteria can use the surface protein InlA to invade intestinal epithelial cells or transcytose across M cells in the gut, but it is not well understood how the bacteria traffic from the underlying lamina propria to the draining mesenteric lymph nodes (MLN). Previous studies indicated that associated with both monocytes and dendritic cells in the intestinal lamina propria.
Introduction: The transition from pediatric to adult healthcare is challenging for adolescents and young adults (AYA) with pediatric-onset chronic health conditions. Although barriers faced by AYA during transition are well-documented, previous studies have not considered how migration and settlement impact patient and family experiences.
Objectives: To fill this gap, we conducted a qualitative descriptive study to explore the recommendations for policy and practice from the perspectives of immigrant and refugee AYA living with chronic health conditions in Canada as they transition from pediatric to adult healthcare.
The cerebrospinal fluid (CSF) border accommodates diverse immune cells that permit peripheral cell immunosurveillance. However, the intricate interactions between CSF immune cells and infiltrating cancer cells remain poorly understood. Here we use fate mapping, longitudinal time-lapse imaging and multiomics technologies to investigate the precise origin, cellular crosstalk and molecular landscape of macrophages that contribute to leptomeningeal metastasis (LM) progression.
