(International Journal of Modern Physics C, 2016-01-01)
Corrections to scaling in the two-dimensional (2D) scalar (Formula presented.) model are studied based on nonperturbative analytical arguments and Monte Carlo (MC) simulation data for different lattice sizes L ((Formula ...

(Journal of Computational and Theoretical Nanoscience, 2013-12-31)
For the first time, we systemically analyze the influence of magneto-thermo-electromechanical effects on the band structure calculations by using the fully coupled model. We focus on three different types of quantum dots ...
• Coupled thermo-electro-mechanical models for thermal ablation of biological tissues and heat relaxation time effects ﻿

(Physics in Medicine & Biology, 2019)
Thermal ablation is a widely applied electrosurgical process in medical treatment of soft biological tissues. Numerical modeling and simulations play an important role in prediction of temperature distribution and ...
• Crystal growth as an excitable medium ﻿

(Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012-12-31)
Crystal growth has been widely studied for many years, and, since the pioneering work of Burton, Cabrera and Frank, spirals and target patterns on the crystal surface have been understood as forms of tangential crystal ...
• Discretizations of the spectral fractional Laplacian on general domains with Dirichlet, Neumann, and Robin boundary conditions ﻿

(2017-04-28)
In this work, we propose novel discretisations of the spectral fractional Laplacian on bounded domains based on the integral formulation of the operator via the heat-semigroup formalism. Specifically, we combine suitable ...
• Dynamic modeling of the morphology of latex particles with in situ formation of graft copolymer ﻿

(Journal of Polymer Science, Part A: Polymer Chemistry, 2012-12-31)
Modification of the polymer-polymer interfacial tension is a way to tailor-make particle morphology of waterborne polymer-polymer hybrids. This allows achieving a broader spectrum of application properties and maximizing ...
• Dynamic modeling of the morphology of multiphase waterborne polymer particles ﻿

(Colloid and Polymer Science, 2013-12-31)
Multiphase waterborne polymer particles provide advantages in more demanding applications, and their performance depends on particle morphology. Currently, no dynamic model for the prediction of the development of the ...
• Effect of Tissue Elasticity in Cardiac Radiofrequency Catheter Ablation Models ﻿

(2018)
Radiofrequency catheter ablation (RFCA) is an effective treatment for different types of cardiac arrhythmias. However, major complications can occur, including thrombus formation and steam pops. We present a full 3D ...
