متن کاملConstructal pattern formation in stony corals, bacterial colonies and plant roots under different hydrodynamics conditions.
This paper explores a new application of the constructal theory, namely in describing and predicting the formation of dissimilar patterns inside elements of the same species under different hydrodynamics conditions. Our study proposes an explanation for the differences found in morphology of stony corals, bacterial colonies and plant roots. It specially provides an answer to the following quest...
متن کاملHormetic electric field theory of pattern formation.
The hormetic morphogen theory of curvature (Fosslien 2009) proposes that hormetic morphogen concentration gradients modulate the synthesis of adenosine triphosphate (ATP) by cells along the gradients (field cells) and thus regulate their proliferation and induce curvature such as vascular wall curvature; however, it is unclear whether such morphogen gradients can also determine the histological...
متن کاملTheory of ocular dominance pattern formation.
We investigate a general and analytically tractable model for the activity-dependent formation of neuronal connectivity patterns. Previous models are contained as limiting cases. As an important example we analyze the formation of ocular dominance patterns in the visual cortex. A linear stability analysis reveals that the model undergoes a Turing-type instability as a function of interaction ra...
متن کاملNote on constructal theory of organization in nature
In analyses of engineering systems, fundamental quest remains the distribution of certain entities (matter, energy) into the space. Thus certain definite forms are generated to serve a specific purpose. Bejan s constructal theory specifically deals with such optimal geometrical constructions. In this present article, equipartition theory is revisited from macroscopic standpoint. It is noted tha...
