Turing-like instabilities from a limit cycle [PDF]

Physical Review E, 2015
The Turing instability is a paradigmatic route to pattern formation in reaction-diffusion systems. Following a diffusion-driven instability, homogeneous fixed points can become unstable when subject to external perturbation. As a consequence, the system evolves towards a stationary, nonhomogeneous attractor.

Turing mechanism underlying a branching model for lung morphogenesis. [PDF]

PLoS ONE, 2017
The mammalian lung develops through branching morphogenesis. Two primary forms of branching, which occur in order, in the lung have been identified: tip bifurcation and side branching.

Semiology of Functional Seizures: Sex‐Related Differences

Brain and Behavior, Volume 16, Issue 7, July 2026.
ABSTRACT Background While functional seizures (FSs) are far more common among women, previous studies found only a few differences between the two sex groups in relation to semiological characteristics. Purpose To compare motor FS semiology between men and women.

Approximate localised dihedral patterns near a turing instability

Nonlinearity, 2023
Abstract Fully localised patterns involving cellular hexagons or squares have been found experimentally and numerically in various continuum models. However, there is currently no mathematical theory for the emergence of these localised cellular patterns from a quiescent state.

Harnessing Generative AI Within Human‐Aligned Constraints: Exploring Control Strategies and Existential Considerations

Engineering Reports, Volume 8, Issue 7, July 2026.
We propose the Powerful‐but‐Limited Generative AI theorem, demonstrating that embedding human‐inspired constraints, such as fixed utility functions and neuro‐symbolic submission layers, ensures generative AI remains controllable by preventing self‐improvement beyond designer intent.

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

Journal of Synchrotron Radiation, Volume 33, Issue 4, Page 1110-1125, July 2026.
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 ...

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Theory of Turing pattern formation and its experimental realization in the CIMA reaction system in the presence of materials lowering the diffusivity of activators

Frontiers in Physics
In 1952, Alan Turing accomplished a pioneering theoretical study to show that the coupling of nonlinear chemical reactions and diffusion leads to the instability of spatially homogeneous states.

Turing instability and Hopf bifurcation in a predator–prey model with delay and predator harvesting

Advances in Difference Equations, 2019
In this paper, we study a predator–prey model with delay and harvesting on predator. We give the conditions for stability and Turing instability of coexisting equilibrium by analyzing the eigenvalue spectrum.
