We have undertaken a measurement campaign to determine the repeatability of the prompt flashlamp-induced wavefront aberration on beamlines at the National Ignition Facility (NIF) and determine the extent to which shot-to-shot variations in this aberration may degrade the performance of a proposed adaptive optics system for the short-pulse Advanced Radiographic Capability beamline on NIF. In this paper we will describe the unique NIF configuration that was required to make this measurement, present the results of the experiment, and discuss the implications of these results for the adaptive optics system design.
Ectoine, an osmolyte produced by various microorganisms, has numerous commercial applications. Vreelandella boliviensis (formerly called Halomonas boliviensis) generates high ectoine concentrations, i.e.
The aim of this study was to assess efficacy of large language models (LLMs) for converting free-text computed tomography (CT) scan reports of head and neck cancer (HNCa) patients into a structured format using a predefined template. A retrospective study was conducted using 150 CT reports of HNCa patients. A comprehensive structured reporting template for HNCa CT scans was developed, and the Generative Pre-trained Transformer 4 (GPT-4) was initially used to convert 50 CT reports into a structured format using this template.
Background: Patients undergoing cardiac surgery are identified as high risk for infection, including MRSA. An outbreak of MRSA was identified when two patients experienced MRSA infection concurrently in a cardiothoracic high dependency unit with uncommon detection of MRSA previously and an established screening programme.
Methods: An outbreak control team was convened and interventions applied including refresher training in hand and environmental hygiene, review of practice with regard to aseptic access of medical devices and consideration of antibiotic use in the unit.
: Culture-negative vertebral osteomyelitis presents a significant diagnostic challenge. () is a typically benign commensal organism of the upper respiratory tract that rarely causes invasive infections, warranting cautious interpretation if isolated in a single positive culture. This case study details a 62-year-old male diagnosed with vertebral osteomyelitis caused by , examining diagnostic challenges, treatment, and outcomes.
The ongoing sustainable reduction in natural resources is prompting companies to look for materials to reuse that were previously classified as waste. Uses are sought for them either in their existing area of use or in other areas of the economy. In many cases, this is difficult.
