Nature Communications, 2019 Branching patterns and regulatory networks differ between branched organs. It has remained unclear whether a common regulatory mechanism exists and how organ-specific patterns can emerge.

Electronic Journal of Qualitative Theory of Differential Equations, 2014 In this paper, we focus on a ratio dependent predator-prey system with self- and cross-diffusion and constant harvesting rate. By making use of a brief stability and bifurcation analysis, we derive the symbolic conditions for Hopf, Turing and wave ...

Kink Arrays and Solitary Structures in Optically Biased Phase Transition
, 1996 An interphase boundary may be immobilized due to nonlinear diffractional interactions in a feedback optical device. This effect reminds of the Turing mechanism, with the optical field playing the role of a diffusive inhibitor.

A Critical Appraisal of Labour's AI Agenda
The Political Quarterly, EarlyView.Abstract This article critically evaluates Labour's ambitious AI agenda, situating it within the historical trajectory of UK AI policy and the techno‐solutionist assumptions underpinning current strategies. While Labour frames AI as a transformative tool for economic growth, state efficiency and public service reform, we argue that structural ...

Mathematics, 2019 Diffusion has long been known to induce pattern formation in predator prey systems. For certain prey-predator interaction systems, self diffusion conditions ceases to induce patterns, i.e., a non-constant positive solution does not exist, as seen from ...

Gender &History, EarlyView.ABSTRACT A new archive of oral history interviews from LGBTQIA‐identified alumni, faculty and staff reveals the complex ways that queer and transgender students understood, experienced and remembered the long transition from single‐sex to coeducation at Princeton University.

BiophysicaAnimal skin patterns are increasingly explained using the Turing pattern model proposed by Alan Turing. The Turing model, a self-organizing model, can produce spotted or striped patterns.

Advances in Difference Equations, 2018 We study the pattern generating mechanism of a generalized Gierer–Meinhardt model with diffusions. We show the existence and stability of the Hopf bifurcation for the corresponding kinetic system under certain conditions.
