Prediction and Comparative Analysis of CTCF Binding Sites based on a First Principle Approach
Nestor Norio Oiwa, Kunhe Li, Claudette E. Cordeiro +1
We calculated the patterns for the CCCTC transcription factor (CTCF) binding sites across many genomes on a first principle approach. The validation of the first principle method w…
The Electronic Behavior of Zinc-Finger Protein Binding Sites in the Context of the DNA Extended Ladder Model
Nestor Norio Oiwa, Claudette Cordeiro, Dieter W. Heermann
The eukaryotic Cys2His2 zinc finger proteins bind to DNA ubiquitously at highly conserved domains, responsible for gene regulation and the spatial organization of DNA. To study and…
Optical Dichroism by Nonlinear Excitations in Graphene Nanoribbons
C. E. Cordeiro, A. Delfino, T. Frederico +2
The honeycomb carbon structure of graphene and nanotubes has a dynamics which can give rise to a spectrum. This can be excited via the interaction with an external electromagnetic…
Vortex and gap generation in gauge models of graphene
O. Oliveira, C. E. Cordeiro, A. Delfino +2
Effective quantum field theoretical continuum models for graphene are investigated. The models include a complex scalar field and a vector gauge field. Different gauge theories are…
Dynamical gap generation in graphene nanoribbons: An effective relativistic field theoretical model
A. J. Chaves, G. D. Lima, W. de Paula +4
We show that the assumption of a nontrivial zero band gap for a graphene sheet within an effective relativistic field theoretical model description of interacting Dirac electrons o…
Effects of anisotropy on a quantum Heisenberg spin glass in a three-dimensional hierarchical lattice
J. Ricardo de Sousa, Beatriz Boechat, Claudette Cordeiro +1
We study the anisotropic Heisenberg spin-glass model in a three-dimensional hierarchical lattice (designed to approximate the cubic lattice), within a real-space renormalization-gr…
