Chaotic Attractor in Tumor Growth and Decay

Authors: Wen-sau Yim, Michael Harney
Comments: 14 Pages.

Cancer growth and decay can be modeled as a system of chaotic nonlinear differential equations. The system is based on a reaction-diffusion cancer growth model, expressed by a mathematical model that is simplified by Ivancevicet. al. This allows useful parameters to be applied for simulation and then recreated in C and Java, to directly compare with its predecessor project. A variation in a set of the parameters is found to decrease tumor growth in the early stages of tumor development.

Heart Dipole Tracking Algorithm

Authors: Michael Harney
Comments: 6 pages

This paper describes a method of tracking the electromagnetic dipole, with a three-dimensional representation of the dipole being graphically displayed in real-time so as to provide diagnostic information about a patient's heart. By knowing the coordinates and orientation of the heart dipole and comparing this data with a healthy heart, cardio-specialists may be able to determine where damaged tissue is located or other diseases in progress.

Klein Bottle Logophysics, Topological Chemistry, the Genetic Code, Universal Rewrite System, Bauplans and the Surmountal of the Cartesian Cut.

Authors: Diego Lucio Rapoport
Comments: 16 pages

We reintroduce logophysics based on self-referential torsion fields and the Klein bottle (KB) logic, which unifies the objective and subjective realms. We apply it to biology, particularly allosterics and the genetic code. We reveal several topologies of the genetic code and its bioinformatics codification, in particular the hyper Klein bottle (HKB) surface. We relate it to the Universal Rewrite System, the Code of Nature, and Dirac algebra.We find that the double helix is unnecessary in this setting, and elaborate the ontology of 3D with regards to time, multistable perception, and a topological (lawless) form of Newton's Third Law. We present the key ideas for a logophysical theory for contextual evolution.

Logistic Equation of Population Growth or Exhaustion of Main Resources: Generalization to the Case of Reactive Environment, Reduction to Abel Ode, Asymptotic Solution for Final Human Population Prognosis.

Authors: Sergey V. Ershkov
Comments: 6 pages.

Here are presented a key points of new universal model for population evolution in reactive environment: 1) generalization of the Logistic equation in the case of reactive environment for population dynamics model in biology (also, for the model of exhaustion of main resources in geology, or for filling of an ecological niches in ecology, or for modeling of capacities of a proper markets in economics), 2) new type of asymptotic solution for such an equation (which is tested on human population growth), 3) reduction of such an equation to Abel ordinary differential equation in general case.

Methods in Environmental Biotechnology for Environmentalists

Authors: W. B. Vasantha Kandasamy, Florentin Smarandache, S. R. Kannan, S. Ramathilagam
Comments: 144 Pages.

The study of environmental pollution by chemicals used in agriculture as pesticide or as fertilizers or pollution caused by industries and chemical plants which use chemicals have not been analysed systematically. This book has five chapters. First chapter is introductory in nature. Here we just study chemical pollution caused by garment industries in chapter two of this book using fuzzy associative memories.

Analysis of Social Aspects of Migrant Labourers Living with Hiv/aids Using Fuzzy Theory and Neutrosophic Cognitive Maps

Authors: W. B. Vasantha Kandasamy, Florentin Smarandache
Comments: 472 pages

Neutrosophic logic grew as an alternative to the existing topics and it represents a mathematical model of uncertainty, vagueness, ambiguity, imprecision, undefined-ness, unknown, incompleteness, inconsistency, redundancy and contradiction. Despite various attempts to reorient logic, there has remained an essential need for an alternative system that could infuse into itself a representation of the real world. Out of this need arose the system of neutrosophy and its connected logic, neutrosophic logic. This new logic, which allows also the concept of indeterminacy to play a role in any real-world problem, was introduced first by one of the authors Florentin Smarandache.

Statistical Modelling of Primary Ewing Tumours of the Bone

Authors: Sreepurna Malakar, Florentin Smarandache, Sukanto Bhattacharya
Comments: 12 pages

This short technical paper advocates a bootstrapping algorithm from which we can form a statistically reliable opinion based on limited clinically observed data, regarding whether an osteo-hyperplasia could actually be a case of Ewing's osteosarcoma. The basic premise underlying our methodology is that a primary bone tumour, if it is indeed Ewing's osteosarcoma, cannot increase in volume beyond some critical limit without showing metastasis. We propose a statistical method to extrapolate such critical limit to primary tumour volume. Our model does not involve any physiological variables but rather is entirely based on time series observations of increase in primary tumour volume from the point of initial detection to the actual detection of metastases.

A Proposed Artificial Neural Network Classifier to Identify Tumor Metastases Part I

Authors: M. Khoshnevisan, Sukanto Bhattacharya, Florentin Smarandache
Comments: 14 pages

In this paper we propose a classification scheme to isolate truly benign tumors from those that initially start off as benign but subsequently show metastases. A non-parametric artificial neural network methodology has been chosen because of the analytical difficulties associated with extraction of closed-form stochastic-likelihood parameters given the extremely complicated and possibly non-linear behavior of the state variables. This is intended as the first of a three-part research output. In this paper, we have proposed and justified the computational schema. In the second part we shall set up a working model of our schema and pilot-test it with clinical data while in the concluding part we shall give an in-depth analysis of the numerical output and model findings and compare it to existing methods of tumor growth modeling and malignancy prediction.
