It is suggested that a system of chemical substances, called morphogens, reacting together and diffusing through a tissue, is adequate to account for the main phenomena of morphogenesis. Such a system, although it may originally be quite homogeneous, may later develop a pattern or structure due to an instability of the homogeneous equilibrium, which is triggered off by random disturbances. Such reaction-diffusion systems are considered in some detail in the case of an isolated ring of cells, a…

A theory of biological pattern formation
It is shown that relatively simple molecular mechanisms based on auto- and cross catalysis can account for a primary pattern of morphogens to determine pattern formation of the tissue, and the theory is applied to quantitative data on hydra and is shown to account for activation and inhibition of secondary head formation.
Co-evolving cellular automata for morphogenesis
This work presents the foundation upon which to develop cellular automata as a tool to simulate the morphodynamics in embryonic development, and introduces two co-evolving automata, one describing the perturbed diffusion of growth factors and one accounting for the rules of basic cellular functions.
A New Approach to Modeling Morphogenesis Using Control Theory
The question of how complex biological cell structures arise from single cells during development can now be posed in terms of a mathematical control problem in which the activation and deactivation of fractones determines how a cellular mass forms.
Origin of multicellular organisms as an inevitable consequence of dynamical systems
The results suggest that the emergence of multicellular organisms is not a “difficult problem” in evolution, but rather is a natural consequence of a cell colony that can grow continuously.
The role of trans-membrane signal transduction in turing-type cellular pattern formation.
A Two-dimensional Growth Process
Examination of properties of populations of cells, in particular, properties relating to the architecture of cell colonies finds little evidence available but it is to be anticipated that, on a cellular level, there would be little more correlation between twins than between any other members of a given species population.
Mathematical modelling of pattern formation in developmental biology
The models presented are formulated based on Turing’s classical mechanism and are used to gain insight into the significance and impact that cells may have in biological phenomena and show a greater applicability to biology with fundamental cell signalling and the interactions involved in Turing type patterning.
Notes on the Turing Instability and Chemical Instabilities
In these notes, I discuss in more detail the nonlinear evolution equations and their linear stability analysis for chemicals that react and diffuse in solutions for chemicals in an initially uniform state.
Orientation of chemotactic cells and growth cones: models and mechanisms.
A model is proposed for an amplification step in chemotactically sensitive cells or growth cones that accounts for their extraordinary directional sensitivity and accounts for the generation of a stable cell polarity.


Some Calculations of the Riemann Zeta-Function
The Manchester University Mark 1 Electronic Computer was used to do some calculations concerned with the distribution of the zeros of the Riemann zeta-function, intended in fact to determine whether there are any zeros not on the critical line in certain particular intervals.

This research presents a classical tool for analyzing e-business (AIL), which is used to disconfirm that telephony and scatter/gather I/O can interfere to accomplish this intent.
Practical Forms of Type Theory
The present paper is an attempt to present the theory of types in forms in which the types themselves only play a rather small part, as they do in ordinary mathematical argument.
A number of methods of solving sets of linear equations and inverting matrices are discussed. The theory of the rounding-off errors involved is investigated for some of the methods. In all cases

It will be shown that the word problem in semi-groups with cancellation is not solvable. The method depends on reducing the unsolvability of the problem in question to a known unsolvable problem
