Effect of migration in a diffusion model for template coexistence in protocells [PDF]
, 2014 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 conditions of short stature: A review of three classic examples
Frontiers in Endocrinology, 2022 Noonan, Turner, and Prader-Willi syndromes are classical genetic disorders that are marked by short stature. Each disorder has been recognized for several decades and is backed by extensive published literature describing its features, genetic origins ...

The parabolic Anderson model on the hypercube [PDF]
, 2016 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 $\xi_n$.

The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]
, 2010 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.

Critical transitions in a model of a genetic regulatory system
Mathematical Biosciences and Engineering, 2014 We consider a model for substrate-depletion oscillations in genetic systems, based on a stochastic differential equation with a slowly evolving external signal. We show the existence of critical transitions in the system. We apply two methods to numerically test the synthetic time series generated by the system for early indicators of critical ...

Genetic Algorithm for Biobjective Urban Transit Routing Problem [PDF]
Journal of Applied Mathematics, 2013 This paper considers solving a biobjective urban transit routing problem with a genetic algorithm approach. The objectives are to minimize the passengers’ and operators’ costs where the quality of the route sets is evaluated by a set of parameters. The proposed algorithm employs an adding-node procedure which helps in converting an infeasible solution ...

A Nexus model of cellular transition in cancer
Biological Research, 2018 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.
