Residual Stress Analysis using Multiparameter Tomographic Reconstruction [PDF]

, 1995
While tomographic reconstruction techniques are commonly utilized for the analysis of electromagnetic (typically x-ray) wave propagation data, this approach is infrequently used to examine acoustic data outside the geophysics community. However, acoustic

The Use of Tractography-Based Targeting in Deep Brain Stimulation for Psychiatric Indications

Frontiers in Human Neuroscience, 2020
Deep Brain Stimulation (DBS) has been investigated as a treatment option for patients with refractory psychiatric illness. Over the past two decades, neuroimaging developments have helped to advance the field, particularly the use of diffusion tensor ...

Reconstruction of shear modulus and viscosity of biological tissues from displacement measurement

Measurement: Sensors, 2021
We present a novel reconstruction method for magnetic resonance elastography, in which the shear modulus and viscosity of biological tissues are estimated from the externally oscillated displacement field obtained using magnetic resonance imaging.

The depth of pseudotachylyte formation from detailed thermochronology and constraints on coseismic stress drop variability [PDF]

, 2012
Pseudotachylytes are accepted as recording paleo-seismicity in the rock record. However, the interpretation of the mechanics of faulting based on pseudotachylyte generation is often hindered because the depth at which they form is poorly constrained ...

Benchmarking Phase Unwrapping Algorithms in Digital Photoelasticity

Applied Sciences
This study benchmarks five phase unwrapping algorithms—Goldstein’s branch-cut, Flynn’s minimum discontinuity, quality-guided, least-squares, and CPULSI—for digital photoelastic stress field reconstruction using a 3D-printed diametrically compressed disk ...

Measurement method for axisymmetric 3D stress-tensor fields using background-oriented schlieren

Mechanical Engineering Journal, 2019
Stress fields affect various characteristics of materials. However, measurement methods for three-dimensional stress fields tend to be complicated because stress tensors generally consist of six independent components.

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
