Pore size estimation in axon-mimicking microfibers with diffusion-relaxation MRI
Jean-Philippe Thiran, Erick Jorge Canales Rodriguez, Marco Pizzolato, Muhamed Barakovic, Tim Bjørn Dyrby
Purpose: This study aims to evaluate two distinct approaches for fiber radius estimation using diffusion-relaxation MRI data acquired in biomimetic microfiber phantoms that mimic hollow axons. The methods considered are the spherical mean power-law approac ...
Hoboken2024Shape Models of Lucy Targets (3548) Eurybates and (21900) Orus from Disk-integrated Photometry
We use our new light curves, along with historical data, to determine the rotation state, photometric properties, and convex shape models of the targets of the Lucy mission (3548) Eurybates and (21900) Orus. We determine a retrograde spin for both targets, ...
IOP Publishing Ltd2023Lightning interaction with the ionosphere
Marcos Rubinstein, Dongshuai Li
Lightning discharges, including cloud-to-ground (CG) and intracloud (IC) lightning, are known to emit electromagnetic pulses (EMPs) in a wide frequency band ranging from few Hz up to hundreds MHz [1]. During the breakdown and ionization processes (mostly f ...
IET2023Verification of selective laser melting heat source models with operando X-ray diffraction data
Helena Van Swygenhoven, Steven Van Petegem, Samy Hocine
The output obtained from operando X-ray diffraction experiments on Ti-6Al-4V is used to verify the accuracy of four FEM models in predicting the temperature evolution of the solidified domain, the cooling rates of the alpha and beta phases, and the influen ...
ELSEVIER2021Boundary Stabilization of Focusing NLKG near Unstable Equilibria: Radial Case
Joachim Krieger, Shengquan Xiang
We investigate the stability and stabilization of the cubic focusing Klein-Gordon equation around static solutions on the closed ball in . First we show that the system is linearly unstable near the static solution for any dissipat ...
2020Three-Dimensional Shapes of Spinning Helium Nanodroplets
Marcel Drabbels, Andrew Daniel Bonnar Clark, Verónica Oliver Álvarez de Lara, Daniela Rupp
A significant fraction of superfluid helium nanodroplets produced in a free-jet expansion has been observed to gain high angular momentum resulting in large centrifugal deformation. We measured single-shot diffraction patterns of individual rotating helium ...
