Background: Peripheral artery disease (PAD) outcomes often rely on the expertise of individual vascular units, introducing potential subjectivity into disease staging. This retrospective, multicenter cohort study aimed to demonstrate the ability of artificial intelligence (AI) to provide disease staging based on inter-institutional expertise by predicting limb outcomes in post-interventional pedal angiograms of PAD patients, specifically in comparison to the inframalleolar modifier in the Global Limb Anatomic Staging System (IM GLASS).

Methods: We used computer vision (CV) based on the MobileNetV2 model, implemented via TensorFlow.

The brain is arguably the most complex human organ and modelling its mechanical behaviour has challenged researchers for decades. There is still a lack of understanding on how this multiphase tissue responds to mechanical loading and how material parameters can be reliably calibrated. While previous viscoelastic models with two relaxation times have successfully captured the response of brain tissue, the Theory of Porous Media provides a continuum mechanical framework to explore the underlying physical mechanisms, including interactions between solid matrix and free-flowing interstitial fluid.

Article Synopsis
  • The study focuses on creating a lightweight and effective acoustic diaphragm using a combination of polyacrylonitrile (PAN) and graphene oxide (GO) through self-assembly techniques.
  • Spray coating is used for a cost-effective and scalable fabrication process, leading to large curved diaphragms.
  • The new PAN/GO diaphragm is significantly thinner and lighter than commercial options, making it ideal for applications requiring reduced weight and size, like portable audio devices.

The first Ebola Virus Disease (EVD) cases in the 2021 Ebola outbreak were reported by the Democratic Republic of the Congo (DRC) Ministry of Health in February. However, 1 week later, the Guinea Ministry of Health reported its first EVD outbreak since April 2016. U.

Carbon fibers are highly valued for their lightweight characteristics, outstanding mechanical properties, and cost-efficiency. However, their limited oxidation resistance and low thermomechanical stability in hot air impose constraints on their utilization. Here, we present an approach to simultaneously achieve high thermomechanical properties and high-temperature oxidation resistance in carbon-ceramic hybrid fibers featuring a highly aligned co-continuous topological structure through a continuous process.
