Powder Metallurgy Processing to Enhance Superelasticity and Shape Memory in Polycrystalline Cu-Al-Ni Alloys: Reference Material for Additive Manufacturing.

Shape memory alloys (SMAs) are functional materials with a wide range of applications, from the aerospace sector to the biomedical field. Nowadays, there is a worldwide interest in developing SMAs through powder metallurgy like additive manufacturing (AM), which allows innovative building processes. However, producing SMAs using AM techniques is particularly challenging because of the microstructure required to obtain optimal functional properties.

[Strategies and Barriers to the Implementation of Continuing Education in Sentinel Hospitals for the Surveillance of COVID-19 Vaccine Safety in Honduras, 2022-2023Formação continuada: estratégias e barreiras de implementação em hospitais sentinela para a vigilância da segurança das vacinas contra a COVID-19 em Honduras, 2022-2023].

Objective: To describe the continuing education strategies implemented as part of the academic training of health workers; related barriers and facilitators; and the perceptions of health workers in sentinel hospitals in Honduras regarding changes in their knowledge.

Methods: The implemented continuing education strategies are described, as are the findings of a questionnaire given to assess health workers' perceptions of the effectiveness of these strategies in the acquisition of knowledge, skills, and competencies related to the surveillance of events supposedly attributable to vaccination, immunization, or adverse events of special interest. Barriers to participation in these strategies is also described.

Does visual or mechanosensory disruption influence risk assessment in coral reef fishes: a preliminary study.

Interpreting and responding to environmental cues from different modalities has survival value. In fish, the role of multimodal perception has been studied in regard to both foraging and risk assessment, with modalities including vision, olfaction, and mechanoreception via lateral lines. We studied reef fish boldness by placing novel objects that obstructed vision, lateral line use, or both into a coral reef environment with native algal samples inside, and then quantifying exploration as a function of obstruction type and as a function of functional diet groups (herbivores, omnivores, carnivores).

Contrast-enhanced to non-contrast-enhanced image translation to exploit a clinical data warehouse of T1-weighted brain MRI.

Background: Clinical data warehouses provide access to massive amounts of medical images, but these images are often heterogeneous. They can for instance include images acquired both with or without the injection of a gadolinium-based contrast agent. Harmonizing such data sets is thus fundamental to guarantee unbiased results, for example when performing differential diagnosis.

Automatic motion artefact detection in brain T1-weighted magnetic resonance images from a clinical data warehouse using synthetic data.

Containing the medical data of millions of patients, clinical data warehouses (CDWs) represent a great opportunity to develop computational tools. Magnetic resonance images (MRIs) are particularly sensitive to patient movements during image acquisition, which will result in artefacts (blurring, ghosting and ringing) in the reconstructed image. As a result, a significant number of MRIs in CDWs are corrupted by these artefacts and may be unusable.
