Ultrafast demagnetization in the sp-d model: a theoretical study

open access: yes, 2007
We propose and analyze a theoretical model of ultrafast light-induced magnetization dynamics in systems of localized spins that are coupled to carriers' spins by sp-d exchange interaction.

A one-dimensional model for theoretical analysis of single molecule experiments

open access: yes, 2006
In this paper we compare two polymer stretching experiments. The outcome of both experiments is a force-extension relation. We use a one-dimensional model to show that in general the two quantities are not equal.

Turbulent convection model in the overshooting region: II. Theoretical analysis

open access: yes, 2012
Turbulent convection models are thought to be good tools to deal with the convective overshooting in the stellar interior. However, they are too complex to be applied in calculations of stellar structure and evolution. In order to understand the physical

Structure/Glass Transition Temperature Relationship of PVAc-b-poly(MA-co-MMA) Terpolymers with Theoretical and Topological Methods [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2013
The glass transition temperature of several PVAc(1)-b-poly(MA-co-MMA) (2) terpolymers with different fractions of methyl acrylate (MA) and methyl methacrylate (MMA) repeating units in random copolymer (block 2) were calculated with Barton, Kwei and ...

Towards a Field Theoretical Stochastic Model for Description of Tumour Growth

open access: yes, 2017
We develop a field theory-inspired stochastic model for description of tumour growth based on an analogy with an SI epidemic model, where the susceptible individuals (S) would represent the healthy cells and the infected ones (I), the cancer cells.

Process-based Organization Design Model: Theoretical Review and Model Conceptualization [PDF]

open access: yes
The complexity of today's business world is translated into complexity of the company's organization design (Galbraith, 2002). Organizations are forced to quickly adapt to emerging complexity if they want to survive. The change is addressing all areas of

Falling chains as variable mass systems: theoretical model and experimental analysis

open access: yes, 2012
In the present paper we revisit, theoretical and experimentally, the fall of a folded U-chain and of a pile-chain. The model calculation implies the division of the whole system into two subsystems of variable mass, allowing to explore the role of ...

Motivating Children and Adolescents in Obesity Treatment

open access: yesJournal of Obesity & Metabolic Syndrome, 2020
Enhancing motivation is a crucial issue in pediatric obesity interventions, as behavioral changes related to food intake and physical exercise are difficult to carry out with an insufficient level of motivation.
