Effect of migration in a diffusion model for template coexistence in protocells [PDF]
The compartmentalization of distinct templates in protocells and the exchange of templates between them (migration) are key elements of a modern scenario for prebiotic evolution.

Genetic instability and transitional cell carcinoma of the bladder
The development of cancer occurs in a stepwise fashion, with each step representing the mutation in one of several key genes. However, the mutation rate of somatic cells is too low to account for the number of mutations required for a cell to undergo carcinogenesis.

The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.

A Nexus model of cellular transition in cancer
The exact cause of cancer is one of the most immutable medical questions of the century. Cancer as an evolutionary disease must have a purpose and understanding the purpose is more important than decoding the cause.

The parabolic Anderson model on the hypercube [PDF]
We consider the parabolic Anderson model $\frac{\partial}{\partial t} v_n=\kappa\Delta_n v_n + \xi_n v_n$ on the $n$-dimensional hypercube $\{-1,+1\}^n$ with random i.i.d. potential $\xi_n$.

Epigenetic regulation of photoperiodic flowering in plants
In response to changeable season, plants precisely control the initiation of flowering in appropriate time of the year to ensure reproductive success.

The origins and physical roots of life’s dual – metabolic and genetic – nature [PDF]
This review paper aims at a better understanding of the origin and physical foundation of life’s dual – metabolic and genetic – nature. First, I give a concise ‘top-down’ survey of the origin of life, i.e., backwards in time from extant DNA/RNA/protein ...

The effective population size is an important concept in population genetics. It corresponds to a measure of the speed at which genetic drift affects a given population.

Transition to chaos in models of genetic networks [PDF]
Randomly constructed networks of N elements governed by piecewise linear differential equations have been proposed as models for neural and genetic networks. In this model an element is labelled “on” if it is above a threshold, and “off” otherwise.

Reaction-diffusion equation for quark-hadron transition in heavy-ion collisions
Reaction-diffusion equations with suitable boundary conditions have special propagating solutions which very closely resemble the moving interfaces in a first order transition.
