A model of octopus epidermis pattern mimicry mechanisms using inverse operation of the Turing reaction model [PDF]

open access: yesPLoS ONE, 2021
Many cephalopods such as octopi and squid can purposefully and rapidly change their skin color. Furthermore, it is widely known that some octopi have the ability to rapidly change the color and unevenness of their skin to mimic their surroundings ...

Turing instability and pattern formation of a fractional Hopfield reaction–diffusion neural network with transmission delay

open access: yesNonlinear Analysis, 2022
It is well known that integer-order neural networks with diffusion have rich spatial and temporal dynamical behaviors, including Turing pattern and Hopf bifurcation.

Turing patterns inside cells. [PDF]

open access: yesPLoS ONE, 2007
Concentration gradients inside cells are involved in key processes such as cell division and morphogenesis. Here we show that a model of the enzymatic step catalized by phosphofructokinase (PFK), a step which is responsible for the appearance of ...

Wavelength of a Turing-type mechanism regulates the morphogenesis of meshwork patterns

open access: yesScientific Reports, 2021
The meshwork pattern is a significant pattern in the development of biological tissues and organs. It is necessary to explore the mathematical mechanism of meshwork pattern formation.

Diffusiophoresis-enhanced Turing patterns

open access: yesScience Advances, 2023
Turing patterns are fundamental in biophysics, emerging from short-range activation and long-range inhibition processes. However, their paradigm is based on diffusive transport processes that yield patterns with shallower gradients than those observed in nature. A complete physical description of this discrepancy remains unknown.

Turing Patterning in Stratified Domains [PDF]

open access: yesBulletin of Mathematical Biology, 2020
AbstractReaction–diffusion processes across layered media arise in several scientific domains such as pattern-formingE. colion agar substrates, epidermal–mesenchymal coupling in development, and symmetry-breaking in cell polarization. We develop a modeling framework for bilayer reaction–diffusion systems and relate it to a range of existing models.

An Intensional Concurrent Faithful Encoding of Turing Machines [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
The benchmark for computation is typically given as Turing computability; the ability for a computation to be performed by a Turing Machine. Many languages exploit (indirect) encodings of Turing Machines to demonstrate their ability to support arbitrary ...

Turing-Hopf patterns in a morphochemical model for electrodeposition with cross-diffusion

open access: yesApplications in Engineering Science, 2021
This paper focuses on the impact of cross-diffusion for Turing-Hopf instability in a morphochemical model for electrodeposition (DIB) and completes the analysis on the role of cross-diffusion on pattern formation in electrodeposition we recently carried ...

Turing patterns in simplicial complexes

open access: yesPhysical Review E, 2023
The spontaneous emergence of patterns in nature, such as stripes and spots, can be mathematically explained by reaction-diffusion systems. These patterns are often referred as Turing patterns to honor the seminal work of Alan Turing in the early 1950s.

Stochastic Turing patterns on a network [PDF]

open access: yesPhysical Review E, 2012
The process of stochastic Turing instability on a network is discussed for a specific case study, the stochastic Brusselator model. The system is shown to spontaneously differentiate into activator-rich and activator-poor nodes, outside the region of parameters classically deputed to the deterministic Turing instability. This phenomenon, as revealed by
