Non-linear effects on Turing patterns: time oscillations and chaos.

, 2012
We show that a model reaction-diffusion system with two species in a monostable regime and over a large region of parameter space, produces Turing patterns coexisting with a limit cycle which cannot be discerned from the linear analysis. As a consequence,

Field test of assumptions for using line transect distance sampling on rock ptarmigan

Wildlife Biology, EarlyView.
Reliable population estimates are essential for the management of harvested species. Line transect distance sampling using pointing dogs is an established survey method for willow ptarmigan and has also been proposed for the monitoring of rock ptarmigan.

An Integrated computational & mammalian synthetic biology framework for engineering turing patterns [PDF]

, 2019
Turing patterns are thought to underlie the formation of many tissue structures during development. First proposed by Alan Turing, two key properties are known to affect the formation of patterns: the fine balance of the interaction parameters and the ...

Turing and animal coat patterns

, 2014
The present article describes a beautiful contribution of Alan Turing to our understanding of how animal coat patterns form. The question that Turing posed was the following.

Paired CycleGAN‐based virtual staining for 3D X‐ray histology of bone‐implant systems

Journal of Synchrotron Radiation, EarlyView.
This work demonstrates virtual staining for 3D X‐ray histology using a modified CycleGAN trained on paired synchrotron radiation microtomography (SR‐µCT) and histology images of bone‐implant specimens. The method enables the generation of artificially coloured contrast resembling conventional histological staining from label‐free SR‐µCT data and is ...

Spikes for the gierer-meinhardt system with many segments of different diffusivities

, 2008
We rigorously prove results on spiky patterns for the Gierer-Meinhardt system with a large number of jump discontinuities in the diffusion coefficient of the inhibitor.

Air attenuation of high power XFEL beams

Journal of Synchrotron Radiation, EarlyView.
The transmission of air, which is used to contain X‐ray beams for radiation safety, is observed to significantly increase with X‐ray power.The Linac Coherent Light Source II, a high‐repetition‐rate X‐ray free‐electron laser (FEL), produces high average power as well as high peak power.

The Turing heritage for plant biology: all spots and stripes?

Quantitative Plant Biology
In ‘The chemical basis of morphogenesis’ (1952), Alan Turing introduced an idea that revolutionised our thinking about pattern formation. He proposed that diffusion could lead to the spontaneous formation of regular patterns.
