Multiscale Modeling and Mathematical Problems Related to Tumor Evolution and Medical Therapy [PDF]

open access: yesComputational and Mathematical Methods in Medicine, 2003
This paper provides a survey of mathematical models and methods dealing with the analysis and simulation of tumor dynamics in competition with the immune system. The characteristic scales of the phenomena are identified and the mathematical literature on models and problems developed on each scale is reviewed and critically analyzed.

More on how and why : a response to commentaries [PDF]

open access: yes, 2013
We are grateful to the commentators for taking the time to respond to our article. Too many interesting and important points have been raised for us to tackle them all in this response, and so in the below we have sought to draw out the major themes ...

Discovering local patterns of co - evolution: computational aspects and biological examples

open access: yesBMC Bioinformatics, 2010
Background Co-evolution is the process in which two (or more) sets of orthologs exhibit a similar or correlative pattern of evolution. Co-evolution is a powerful way to learn about the functional interdependencies between sets of genes and cellular ...

The Nonlinear Evolution Equations Related to the Wadati-Konno-Ichikawa Spectral Problem [PDF]

open access: yesProgress of Theoretical Physics, 1983
Summary: The Wadati-Konno-Ichikawa (WKI) spectral problem is considered and the nonlinear evolution equations (NLEE) related to this problem are explicitly constructed. Together with the integrable NLEE already found by WKI new pure differential solvable NLEEs are derived.

A splitting/polynomial chaos expansion approach for stochastic evolution equations. [PDF]

open access: yes, 2020
In this paper, we combine deterministic splitting methods with a polynomial chaos expansion method for solving stochastic parabolic evolution problems. The stochastic differential equation is reduced to a system of deterministic equations that we solve ...

Haplodiploidy and the evolution of eusociality : worker reproduction [PDF]

open access: yes, 2013
The authors acknowledge the European Research Council, the Royal Society, and Balliol College for funding.Hamilton’s haplodiploidy hypothesis suggests that the relatively higher relatedness of full sisters in haplodiploid populations promotes altruistic ...

Numerical solution of the nonlinear evolutional inverse problem related to elastoplastic torsional problem

open access: yesApplicable Analysis, 2013
AbstractThis paper is devoted to the determination of an unknown function that describes elastoplastic properties of a bar under torsion. The mathematical (evolution) model leads to an inverse problem that consists of determining the unknown coefficient , in the nonlinear parabolic equation , , , using measured output data given in the integral form ...
