Effect of quantum fluctuations on structural phase transitions in SrTiO_3 and BaTiO_3

open access: yes, 1995
Using path-integral Monte Carol simulations and an ab initio effective Hamiltonian, we study the effects of quantum fluctuations on structural phase transitions in the cubic perovskite compounds SrTiO3 and BaTiO3.

Sustainable Carbon Fiber Composites Based on Recyclable Bio‐Based Vanillin Thermoset Polymers

open access: yesPolymer Composites, EarlyView.
Development of composite materials made from a bio‐based and mechanically recycled vitrimeric polymer matrix. ABSTRACT Although bisphenol A (BPA) is the most used organic compound in the production of thermosets for composite materials, there has been an urgent scientific concern to eliminate it in the last years due to the environmental issues raised ...

Level Crossing Rate and Average Fade Duration of the Multihop Rayleigh Fading Channel

open access: yes, 2008
We present a novel analytical framework for the evaluation of important second order statistical parameters, as the level crossing rate (LCR) and the average fade duration (AFD) of the amplify-and-forward multihop Rayleigh fading channel.

A multidomain spectral method for solving elliptic equations [PDF]

open access: yes, 2002
We present a new solver for coupled nonlinear elliptic partial differential equations (PDEs). The solver is based on pseudo-spectral collocation with domain decomposition and can handle one- to three-dimensional problems.

Influence of the Chemical Composition on the Perovskites Anharmonicity: Toward a Stable Inorganic Perovskite

open access: yesSolar RRL, EarlyView.
This study investigates the effect of the chemical composition on the properties of A(BB’)(XX’)3$_3$ inorganic halide perovskites with density functional theory. By correlating distortion amplitudes with both composition and the Goldschmidt tolerance factor, we propose a pragmatic approach to designing more stable and efficient perovskites, advancing ...

A Classification of Flows on AFD Factors with Faithful Connes--Takesaki Modules [PDF]

open access: yes, 2014
We classify flows on AFD factors with faithful Connes-Takesaki modules. This is a generalization of classification of trace-scaling flows on the AFD $\mathrm{II}_\infty$ factor, which is equivalent to the uniqueness of the AFD $\mathrm{III}_1$ factor. In

Theoretical simulation of the anisotropic phases of antiferromagnetic thin films [PDF]

open access: yes, 2006
We simulate antiferromagnetic thin films. Dipole-dipole and antiferromagnetic exchange interactions as well as uniaxial and quadrupolar anisotropies are taken into account. Various phases unfold as the corresponding parameters, J, D and C, as well as the

Developing Workforce Capability in the Context of HR Ecosystem Learning

open access: yesHuman Resource Management Journal, EarlyView.
ABSTRACT For many organizations, developing workforce capabilities is central as it involves refining critical human resource processes such as upskilling or the acquisition of new profiles. These processes are becoming increasingly complex to manage as organizations collaborate within larger work ecosystems. Surprisingly, little research has addressed

Atypical Distribution of Late Gadolinium Enhancement of the Left Ventricle on Cardiac Magnetic Resonance in Classical Anderson-Fabry Disease

open access: yesJournal of the Belgian Society of Radiology, 2016
Anderson-Fabry disease (AFD) is an X-linked lysosomal storage disorder caused by a deficiency of alpha-galactosidase A. Approximately 50% of patients with AFD may have cardiac involvement.
