Imaging of barely visible impact damage on a complex composite stiffened panel using a nonlinear ultrasound stimulated thermography approach
Thermosonics, also known as ultrasonic stimulated thermography, is a rapid non-destructive evaluation technique that uses an infrared camera to visualise material defects by detecting the frictional heating at crack surfaces...
SHM of Single Lap Adhesive Joints using Subharmonic Frequencies
The increased usage of adhesive bonding as a joining method in modern aerospace components has led to developing reliable ultrasonic health monitoring systems for detection of regions of poor adhesion. Nonlinear...
Anomalous Stochastic Transport of Particles with Self-Reinforcement and Mittag-Leffler Distributed Rest Times
We introduce a persistent random walk model for the stochastic transport of particles involving self-reinforcement and a rest state with Mittag–Leffler distributed residence times. The model involves a system of...
A unified framework for analysis of individual-based models in ecology and beyond.

Oct 16, 2020
Individual-based models, 'IBMs', describe naturally the dynamics of interacting organisms or social or financial agents. They are considered too complex for mathematical analysis, but computer simulations of them cannot give the...
Nonlinear ultrasonic stimulated thermography for damage assessment in isotropic fatigued structures
Gian Piero Malfense Fierro, Danielle Calla, Dmitri Ginzburg, Francesco Ciampa, Michele Meo
Sep 15, 2017
Traditional non-destructive evaluation (NDE) and structural health monitoring (SHM) systems are used to analyse that a structure is free of any harmful damage. However, these techniques still lack sensitivity to detect the...

Surface Crystallization of Liquid Au-Si and Its Impact on Catalysis.
Federico Panciera, Jerry Tersoff, Andrew D Gamalski, Mark C Reuter, Dmitri Zakharov, Eric A Stach, Stephan Hofmann, Frances M Ross
Dec 17, 2018
In situ transmission electron microscopy reveals that an atomically thin crystalline phase at the surface of liquid Au-Si is stable over an unexpectedly wide range of conditions. By measuring the surface structure as a function...
Hydrogen storage performance of the multi-principal-component CoFeMnTiVZr alloy in electrochemical and gas-solid reactions.
Why are the 2-oxoacid dehydrogenase complexes so large? Generation of an active trimeric complex
Nia Marrott, Jacqueline J. T. Marshall, Dmitri I Svergun, Susan Crennell, D W Hough, Jean Van Den Elsen, Michael Danson
Nov 01, 2014
The four-component polypeptides of the 2-oxoacid dehydrogenase complex from the thermophilic archaeon Thermoplasma acidophilum assemble to give an active multienzyme complex possessing activity with the branched-chain 2-oxoacids...
