Desenvolvimento de modelos mesoscópicos tridimensionais para o estudo da desnaturação em DNA
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2021-01-29)
Análise da divergência na integral de transferência do modelo Peyrard-Bishop de DNA
(Universidade Federal de Minas GeraisUFMG, 2016-03-17)
The Peyrard-Bishop model is a classical approach to describe the molecular interaction in DNA and RNA, where the double strand is considered as perfectly flat, without the characteristic helical torsion. The model Hamiltonian ...
Formação e estabilidade de Breathers no modelo de Peyrard-Bishop para o DNA
(Universidade Estadual Paulista (UNESP), 2014)
A Model Coupling Vibrational and Rotational Motion for the DNA Molecule
(Springer, 2008-01-01)
We investigate a mechanical model for the DNA molecule using an extension of the Peyrard and Bishop model. In the present model, there are two chains of oscillators linked by a Morse potential, which represent the hydrogen ...
Analysis of Lattice Size, Energy Density and Denaturation for a One-Dimensional DNA Model
(2012)
There are several mechanical models to describe the DNA phenomenology. In this work the DNA denaturation is stu- died under thermodynamical and dynamical point of view using the well known Peyrard-Bishop model. The ...

Thermodynamic analysis of a non linear lattice
(Sociedade Brasileira de Física, 2008-09-01)
We investigate an extension of the Perard and Bishop (PB) model. In the studied model we get a harmonic one dimensional lattice chain with an additional Morse potential on site. The rotation and vibration motion of each ...

Estudos das propriedades de inosina em DNA através do modelo Peyrard-Bishop e análise dos parâmetros termodinâmicos utilizados na predição de estruturas secundárias de RNA
(Universidade Federal de Minas GeraisUFMG, 2018-02-06)
In this thesis we present different studies on the properties of nucleic acids regarding both structure and their composition. After an brief overview on deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and the inosine ...
