An Inductively-Coupled Plasma Electrothermal Radiofrequency Thruster
Frontiers in Physics, 2020 The “cubesat” form factor has been adopted as the defacto standard for a cost effective and modular, nano-satellite platform. Many commercial options exist for nearly all components required to build such satellite; however, there is a limited range of ...

High‐power short‐duration versus standard radiofrequency ablation: Insights on lesion metrics
Cardiovascular Electrophysiology, 2018 Radiofrequency (RF) lesion metrics are influenced by underlying parameters like RF power, duration, and contact force (CF), and utilization of lesion metric indices (ablation index [AI]) is a proposed strategy to predict lesion quality.

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI
Chemie Ingenieur Technik, EarlyView.This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Reflex seizures and epilepsy surgery: A network approach case‐based exploration
Epileptic Disorders, EarlyView.Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

Epilepsia, EarlyView.Abstract Objective The detection of subtle epileptogenic lesions such as focal cortical dysplasias (FCDs) is a clinical challenge in the management of drug‐resistant focal epilepsy (DRFE). Ultra‐high‐field (UHF) magnetic resonance imaging (MRI) offers increased signal‐to‐noise ratios and spatial resolution compared to 3‐T MRI and may improve diagnostic
