Photosynthesis involves a very large number of photochemical and chemical transformations. This review focuses on the extraordinarily rapid transport of excitation energy in the antenna pigmentprotein...
A Simple Model of Unbounded Evolutionary Versatility as a Largest-Scale Trend in Organismal Evolution
Largest-Scale Trend Organismal Evolution
2015/7/31
The idea that there are any large-scale trends in the evolution of biological organisms is
highly controversial. It is commonly believed, for example, that there is a large-scale trend in
evolution ...
In this work a new approach to multidimensional geometry and multidimensional physics based on smooth infinitesimal analysis (SIA) is proposed. Reality may be considered as the process of time evoluti...

Biased swimming cells do not disperse in pipes as tracers: a population model based on microscale behaviour
Algae dispersion swimming pipe
2012/5/17
There is much current interest in modelling suspensions of algae and other micro-organisms for biotechnological exploitation, and many bioreactors are of tubular design. Using generalized Taylor dispe...
Low-parameter phylogenetic estimation under the general Markov model
Markov invariants phylogenetic invariants base-composition rate-variation quartets supertrees
2012/5/2
In their 2008 and 2009 papers, Sumner and colleagues introduced the "squangles" - a small set of Markov invariants for phylogenetic quartets. The squangles are consistent with the general Markov model...
Hypoxic Cell Waves around Necrotic Cores in Glioblastoma: A Biomathematical Model and its Therapeutic Implications
Glioblastoma multiforme tumor hypoxia pseudopalisades invasion mathematical model
2012/5/2
Glioblastoma is a rapidly evolving high-grade astrocytoma that is distinguished pathologically from lower grade gliomas by the presence of necrosis and microvascular hiperplasia. Necrotic areas are ty...
Tensegrity and Motor-Driven Effective Interactions in a Model Cytoskeleton
Tensegrity Motor-Driven Effective Interactions Model Cytoskeleton Biological Physics
2012/4/24
Actomyosin networks are major structural components of the cell. They provide mechanical integrity and allow dynamic remodeling of eukaryotic cells, self-organizing into the diverse patterns essential...
A Mathematical Model for Estimating Biological Damage Caused by Radiation
cell density radiation protection radiation risk apoptosis mutation DNA repair mathematical model low-dose exposure irradiation rate Living object
2012/4/20
We propose a mathematical model for estimating biological damage caused by low-dose irradiation. We understand that the Linear Non Threshold (LNT) hypothesis is realized only in the case of no recover...
Numerical study of linear and circular model DNA chains confined in a slit: metric and topological properties
Numerical study linear and circular model DNA chains metric and topological properties Biological Physics
2012/4/20
Advanced Monte Carlo simulations are used to study the effect of nano-slit confinement on metric and topological properties of model DNA chains. We consider both linear and circularised chains with co...
Some Exact Self-Similar Solutions to a Density-Dependent Reaction-Diffusion Model
Exact Self-Similar Density-Dependent Reaction-Diffusion Model Biological Physics
2012/4/20
In this paper, we investigated a density-dependent reaction-diffusion equation, $u_t = (u^{m})_{xx} + u - u^{m}$. This equation is known as the extension of the Fisher or Kolmogoroff-Petrovsky-Piscoun...
DNA Self-Assembly and Computation Studied with a Coarse-grained Dynamic Bonded Model
DNA Self-Assembly Computation Studied Coarse-grained Dynamic Bonded Model Biological Physics
2012/5/3
We utilize a coarse-grained directional dynamic bonding DNA model [C. Svaneborg, Comp. Phys. Comm. (In Press DOI:10.1016/j.cpc.2012.03.005)] to study DNA self-assembly and DNA computation. In our DNA ...

Predicting effects structural stress genome-reduced model bacterial metabolism
2012/2/28
We studied in silico effects of structural stress in Mycoplasma pneumoniae, a genome-reduced model bacterial organism, by tracking the damage propagating on its metabolic network after a deleterious p...
