Cybersecurity: Positive Changes Through Processes and Team Culture.

Protecting your organization's technology systems, devices, and electronic information is more important than ever before as healthcare increasingly becomes a target for cyberattacks, phishing, and ransomware. Hackers have turned this cyber warfare into a multibillion-dollar business, and the attacks are only getting worse. No company or individual is immune to the risks of cyberattacks, which can not only damage an organization's operations and reputation but also affect patient care quality and safety.

Potential Impact of a Validated Screening Tool for Pediatric Abusive Head Trauma.

Objective: To conduct a retrospective, theoretical comparison of actual pediatric intensive care unit (PICU) screening for abusive head trauma (AHT) vs AHT screening guided by a previously validated 4-variable clinical prediction rule (CPR) in datasets used by the Pediatric Brain Injury Research Network to derive and validate the CPR.

Study Design: We calculated CPR-based estimates of abuse probability for all 500 patients in the datasets. Next, we demonstrated a positive and very strong correlation between these estimates of abuse probability and the overall diagnostic yields of our patients' completed skeletal surveys and retinal examinations.

Numerical simulations of the Richtmyer-Meshkov instability in solid-vacuum interfaces using calibrated plasticity laws.

The Richtmyer-Meshkov instability of interfaces separating elastic-plastic materials from vacuum (heavy-light configuration) is studied by means of computational techniques. A fully Eulerian multimaterial algorithm that solves consistently the Euler equations and the time evolution of the deformations in the material is applied to three distinct materials (copper, aluminum, and stainless steel). If a perfectly plastic constitutive relation is considered, an empirical law is computed that relates the long-term perturbation amplitude of the interface, its maximum growth rate, the initial density, and the yield stress of the material.
