Determining Cosserat constants of 2D cellular solids from beam models [PDF]

, 2017
We present results of a two-scale model of disordered cellular materials where we describe the microstructure in an idealized manner using a beam network model and then make a transition to a Cosserat-type continuum model describing the same material on ...

Multi-stage hot deformation and dynamic recrystallization behavior of low-cost Ti–Al–V–Fe alloy via electron beam cold hearth melting

Journal of Materials Research and Technology, 2022
To explore the optimal thermomechanical processing parameters (TMP) of Ti–Al–V–Fe alloys with direct rolling potential after electron beam cold hearth melting (EBCHM) and the grain refinement mechanism during thermal deformation, the multi-pass hot ...

Molecular-Atomic Transition in the Deuterium Hugoniot with Coupled Electron Ion Monte Carlo

, 2014
We have performed accurate simulations of the Deuterium Hugoniot using Coupled Electron Ion Monte Carlo (CEIMC). Using highly accurate quantum Monte Carlo methods for the electrons, we study the region of maximum compression along the principal Hugoniot,

Properties of continuous Fourier extension of the discrete cosine transform and its multidimensional generalization

, 2003
A versatile method is described for the practical computation of the discrete Fourier transforms (DFT) of a continuous function $g(t)$ given by its values $g_{j}$ at the points of a uniform grid $F_{N}$ generated by conjugacy classes of elements of ...

Influence of endodontic motors on the behaviour of root canal shaping instruments: an in vitro comparative study

BDJ Open, 2023
Aims The endodontic literature reports a lot of comparative study on endodontic instruments, concerning as well their geometry, instrumental dynamics, material, mechanical behavior or heat treatment. However, to our knowledge, no study has focused on the

Distributed Parametric Effect in Long Lines and its Applications

, 2011
The article considers a parametric effect which takes place when the velocity of signal propagation in a long line changes. We found the analytical solution describing the form of the transformed signal for a line with losses, when line parameters change

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
