The microscopic model of BiFeO3 [PDF]

open access: yesPhysica B: Condensed Matter, 2018
Many years and great effort have been spent constructing the microscopic model for the room temperature multiferroic BiFeO3 However, earlier models implicitly assumed that the cycloidal wavevector q was confined to one of the three-fold symmetric axis in the hexagonal plane normal to the electric polarization.

How to Impose Microscopic Reversibility in Complex Reaction Mechanisms [PDF]

open access: yes, 2004
Most, but not all, ion channels appear to obey the law of microscopic reversibility (or detailed balance). During the fitting of reaction mechanisms it is therefore often required that cycles in the mechanism should obey microscopic reversibility at all ...

GAUSSIAN FLUCTUATIONS OF POLARIZATION IN THE REGION OF PHASE TRANSITIONS IN DMAGAS-DMAALS FERROELECTRICS IN THE FRAMEWORK OF THE FOUR-STATE MODEL

open access: yesCondensed Matter Physics, 2004
A description of thermodynamics of the DMAGaS-DMAAlS family ferroelectrics improved by taking into account the Gaussian fluctuations of polarization is presented. Fluctuations become important in the vicinity of the second order (or the first order close

Modeling of the Partial Discharge Process in a Liquid Dielectric: Effect of Applied Voltage, Gap Distance, and Electrode Type

open access: yesEnergies, 2013
The partial discharge (PD) process in liquid dielectrics is influenced by several factors. Although the PD current contains the information representing the discharge process during the PD event, it is difficult to determine the detailed dynamics of what

Multi-step particle emission probabilities in superheavy nuclei at moderate excitation energies

open access: yesPhysics Letters B, 2023
The probabilities of xn-, pxn-, and αxn-evaporation channels in excited superheavy nuclei were evaluated using the Monte Carlo method. The calculations utilized microscopically determined nuclear level densities and were compared with results obtained ...

Microscopic model of cuprate superconductivity [PDF]

open access: yesInternational Journal of Quantum Chemistry, 2010
AbstractWe present a model for cuprate superconductivity based on the identification of an experimentally detected “local superconductor” as a charge 2 fermion pairing in a circular, stationary density wave. This wave acts like a highly correlated local “boson” satisfying a modified Cooper problem with additional correlation stabilization relative to ...

Fluid-dynamical and microscopic description of traffic flow: a data-driven comparison [PDF]

open access: yes, 2010
A lot of work has been done to compare traffic flow models with reality; so far, this has been done separately for microscopic as well as for fluid-dynamical models of traffic flow. This paper compares directly the performance of both types of models

Microscopic shell-model counterpart of the Bohr–Mottelson model [PDF]

open access: yes, 2021
In the present paper we demonstrate that there exists a fully microscopic shell-model counterpart of the Bohr–Mottelson model by embedding the latter in the microscopic shell-model theory of atomic nucleus within the framework of the recently proposed ...

Analysis and comparison of traffic flow models: a new hybrid traffic flow model vs benchmark models

open access: yesEuropean Transport Research Review, 2021
Background This paper compares a hybrid traffic flow model with benchmark macroscopic and microscopic models. The proposed hybrid traffic flow model may be applied considering a mixed traffic flow and is based on the combination of the macroscopic cell ...

An Intelligent Decision Support System for Leukaemia Diagnosis using Microscopic Blood Images [PDF]

open access: yes, 2015
This research proposes an intelligent decision support system for acute lymphoblastic leukaemia diagnosis from microscopic blood images. A novel clustering algorithm with stimulating discriminant measures (SDM) of both within- and between-cluster scatter
