Image Encoding With Blipped Gradients in an Echo Train

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose An MRI scanner was designed and built to encode k$$ k $$‐space points in the spin echoes occurring between 180∘$$ 18{0}^{\circ } $$ pulses in an echo train by using blipped B0$$ {B}_0 $$ gradient pulses applied just prior to those spin echoes.

Native Label‐Free Spectral Biochemical Fingerprinting of an Enveloped Mammalian RNA Virus Reveals Mode of Action of a Virucidal Drug

Small Methods, EarlyView.
Deep‐Ultraviolet Resonance Raman (DUVRR) spectroscopy is introduced as a label‐free, non‐invasive analytical workflow for the biochemical fingerprinting of enveloped viruses. By integrating bottom‐up stoichiometric reconstruction with top‐down biochemical extraction, this strategy accurately disentangles complex viral compositions in physiological‐like

Model‐Based Cybersecurity: Automating Common Vulnerabilities Reporting

Systems Engineering, EarlyView.
ABSTRACT The Common Vulnerabilities and Exposures (CVE) Program's mission is to identify, define, and catalog publicly disclosed cybersecurity vulnerabilities. A cybersecurity practitioner who suspects a software, hardware, or service vulnerability, can initiate a CVE‐ID Requesting process, as defined by MITRE.
