Numerical Simulation of Electrical Properties in Cortical and Trabecular Bone: A Simplified Model
María José Cervantes, Catalina A. Cely-Ortíz, C. Manuel Carlevaro +1
The electrical properties of biological tissues depend on their composition and microstructure and determine their response to applied electric fields. In bone tissue, these proper…
A sparse coding approach to inverse problems with application to microwave tomography
Cesar F. Caiafa, Ramiro M. Irastorza
Inverse imaging problems that are ill-posed can be encountered across multiple domains of science and technology, ranging from medical diagnosis to astronomical studies. To reconst…
Phaseless Microwave Imaging Of Dielectric Cylinders: An Artificial Neural Networks-Based Approach
Jesús E. Fajardo, Julián Galván, Fernando Vericat +2
An inverse method for parameters estimation of infinite cylinders (the dielectric properties, location, and radius) in two dimensions from amplitude-only microwave information is p…
Microwave Tomography with phaseless data on the calcaneus by means of artificial neural networks
Jesús E. Fajardo, Federico P. Lotto, Fernando Vericat +2
The aim of this study is to use a Multilayer Perceptron (MLP) Artificial Neural Network (ANN) for phaseless imaging the human heel (modeled as a bilayer dielectric media: bone and…
Uncertainties in permittivities computed from molecular dynamics simulations and temperature correction of dielectric properties of condensed polar systems
Hernán R. Sánchez, Ramiro M. Irastorza, C. Manuel Carlevaro
A robust, simple and fast procedure for the calculation of uncertainties in relative static dielectric permittivity () computed via molecular dynamics (MD) is propos…
Sensitivity analysis on imaging the calcaneus using microwaves
Jesús E. Fajardo, Fernando Vericat, Guadalupe Irastorza +2
The bone quality is asociated with changes in its dielectric properties (permittivity and conductivity). The feasibility of detecting changes in these properties is evaluated using…
Chirality in a quaternionic representation of the genetic code
C. Manuel Carlevaro, Ramiro M. Irastorza, Fernando Vericat
A quaternionic representation of the genetic code, previously reported by the authors, is updated in order to incorporate chirality of nucleotide bases and amino acids. The origina…
Quaternionic representation of the genetic code
C. Manuel Carlevaro, Ramiro M. Irastorza, Fernando Vericat
A heuristic diagram of the evolution of the standard genetic code is presented. It incorporates, in a way that resembles the energy levels of an atom, the physical notion of broken…
Modelling of the dielectric properties of trabecular bone samples at microwave frequency
Ramiro M. Irastorza, Eugenia Blangino, Carlos M. Carlevaro +1
In this paper the dielectric properties of human trabecular bone are evaluated under physiological condition in the microwave range. Assuming a two components medium, simulation an…
Exact predictions from Edwards ensemble vs. realistic simulations of tapped narrow two-dimensional granular columns
Ramiro M. Irastorza, C. Manuel Carlevaro, Luis A. Pugnaloni
We simulate via a Discrete Element Method the tapping of a narrow column of disk under gravity. For frictionless disks, this system has a simple analytic expression for the density…
Is there any information on micro-structure in microwave tomography of bone tissue?
Ramiro M. Irastorza, C. Manuel Carlevaro, Fernando Vericat
In this work, two-dimensional simulations of the microwave dielectric properties of models with ellipses and realistic models of trabecular bone tissue are performed. In these simu…
