The effect of stretching on transmural shear wave anisotropy in cardiac shear wave elastography Universiteit Gent
The Stereoscopic Anisotropy Develops During Childhood KU Leuven
PURPOSE: Human vision has a puzzling stereoscopic anisotropy: horizontal depth corrugations are easier to detect than vertical depth corrugations. To date, little is known about the function or the underlying mechanism responsible for this anisotropy. Here, we aim to find out whether this anisotropy is independent of age. To answer this, we compare detection thresholds for horizontal and vertical depth corrugations as a function of age. METHODS: ...
Contrasting anisotropy of light absorption and emission by semiconductor nanoparticles Universiteit Gent
On the exact nature of the coupled-fields of magneto-electro-elastic ellipsoidal inclusions with non-uniform eigenfields and general anisotropy Universiteit Gent
Computing Curie temperature of two-dimensional ferromagnets in the presence of exchange anisotropy Universiteit Antwerpen KU Leuven
We compare three first-principles methods of calculating the Curie temperature in two-dimensional (2D) ferromagnetic materials (FM), modeled using the Heisenberg model, and propose a simple formula for estimating the Curie temperature with high accuracy that works for all common 2D lattice types. First, we study the effect of exchange anisotropy on the Curie temperature calculated using the Monte Carlo (MC), the Green's function, and the ...
Tuning the intrinsic anisotropy with disorder in the CaKFE₄As₄ superconductor Universiteit Antwerpen
We report on the anisotropy of the London penetration depth of CaKFe4As4, discussing how it relates to its electronic structure and how it modifies under introduction of disorder, both chemically induced (by Ni substitution) and irradiation induced (by 3.5-MeV protons). Indeed, CaKFe4As4 is particularly suitable for the study of fundamental superconducting properties due to its stoichiometric composition, exhibiting clean-limit behavior in the ...
Towards realistic parametrization of the kinetic anisotropy and the resulting instabilities in space plasmas. Electromagnetic electron–cyclotron instability in the solar wind KU Leuven
Measured in situ, the particle velocity distributions in the solar wind plasma reveal two distinct components: a Maxwellian (thermal) core, and a less dense but hotter suprathermal halo with a power-law distribution described by Lorentzian/Kappa distribution function. Despite this evidence, the existing attempts to parametrize anisotropic distributions and the resulting wave instabilities are limited to idealized models, which either ignore the ...
Hierarchical multi-level modelling of plastic anisotropy using convex plastic potentials KU Leuven
A new approach, the "Facet" method, is proposed to implement the anisotropic plastic behaviour of textured materials in finite element models for the simulation of metal forming, It is based on an analytical expression of plastic potentials in strain rate space and/or stress space, The method has been designed to be used in combination with a multilevel model for the plastic deformation of the polycrystalline material. The parameters of the ...
Benchmarking of different strategies to include anisotropy in a curvature-driven multi-phase-field model KU Leuven
Two benchmark problems for quantitative assessment of anisotropic curvature driving force in phase field method were developed and introduced. Both benchmarks contained an anisotropically shrinking grain in homogeneous matrix. The first benchmark was a shrinking Wulff shape and in the second, such inclination dependence of the kinetic coefficient was added so that the shrinkage was isotropic. In both cases the match to the expected shape was ...
