Incremental ECAP of Plates [PDF]

Materials Science Forum, 2008
Batch severe plastic deformation (SPD) processes are mainly used for laboratory purposes. More industrially oriented are continuous processes among which the new SPD process of Incremental Equal Channel Angular Pressing (I-ECAP) is an attractive option.

Impact of geometric factors and shear stress on endothelial function: Hemodynamic insights from human cerebral arterial bifurcations. [PDF]

Physiol Rep
Abstract Vascular inflammation is not a random biological event but rather a process that is strictly regulated by physical forces. While biochemical mediators are well characterized, the local physical mechanisms that predispose specific cerebral vascular sites to inflammation, specifically the geometry of arterial bifurcations, remain ...

Integrated Assessment of Wall Shear Stress-Related Hemodynamic Parameters in Abdominal Aortic Aneurysms: A Retrospective Cross-Sectional Study on Ruptured Cases. [PDF]

Int J Numer Method Biomed Eng
Abdominal aortic aneurysms (AAAs) pose a substantial threat to public health due to their risk of rupture, which can be life‐threatening. Current clinical practice relies primarily on AAA diameter and growth rate as indicators to determine if surgical treatment is imperative. This study investigates the integration of WSS‐related hemodynamic parameters,

Electrically Evoked Compound Action Potentials in Spinal Cord Stimulation: Implications for Preclinical Research Models

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives The study aimed to assess the feasibility of recording electrically evoked compound action potentials (ECAPs) from the rat spinal cord. To achieve this, we characterized electrophysiological responses of dorsal column (DC) axons from electrical stimulation and quantified the relationship between ECAP and motor thresholds (ECAPTs and

A Clinical Feasibility Study of Spinal Evoked Compound Action Potential Estimation Methods

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Spinal cord stimulation (SCS) is a treatment for chronic neuropathic pain. Recently, SCS has been enhanced further with evoked compound action potential (ECAP) sensing. Characteristics of the ECAP, if appropriately isolated from concurrent stimulation artifact (SA), may be used to control, and aid in the programming of, SCS systems.

Effect of Equal Channel Angular Pressing on the Microstructure and Mechanical Properties of an Mg–5Sn Alloy

Metals, 2022
An Mg–5Sn alloy was processed by equal channel angular pressing (ECAP) for different passes (4P, 8P, and 12P), and the microstructure evolution and mechanical properties were investigated. The grain size, amount of Mg2Sn precipitates, and texture of ECAP

Noise Reduction for Single-Shot Grating-Based Phase-Contrast Imaging at an X-ray Backlighter

Journal of Imaging, 2021
X-ray backlighters allow the capture of sharp images of fast dynamic processes due to extremely short exposure times. Moiré imaging enables simultaneously measuring the absorption and differential phase-contrast (DPC) of these processes. Acquiring images
