Pattern Formation in Active Fluids [PDF]
Physical Review Letters, 2011 We discuss pattern formation in active fluids in which active stress is regulated by diffusing molecular components. Nonhomogeneous active stress profiles create patterns of flow which transport stress regulators by advection. Our work is motivated by the dynamics of the actomyosin cell cortex in which biochemical pathways regulate active stress.

Nonlinear patterns shaping the domain on which they live
New Journal of Physics, 2020 Nonlinear stripe patterns in two spatial dimensions break the rotational symmetry and generically show a preferred orientation near domain boundaries, as described by the famous Newell–Whitehead–Segel (NWS) equation.

Patterning and Compartment Formation in the Diencephalon [PDF]
Frontiers in Neuroscience, 2012 The diencephalon gives rise to structures that play an important role in connecting the anterior forebrain with the rest of the central nervous system. The thalamus is the major diencephalic derivative that functions as a relay station between the cortex and other lower order sensory systems.

Pattern Formation and Tropical Geometry
Frontiers in Physics, 2020 Sandpile models exhibit fascinating pattern structures: patches, characterized by quadratic functions, and line-shaped patterns (also called solitons, webs, or linear defects).

Piezo1 mutant zebrafish as a model of idiopathic scoliosis
Frontiers in GeneticsScoliosis is a condition where the spine curves sideways, unique to humans due to their upright posture. However, the cause of this disease is not well understood because it is challenging to find a model for experimentation. This study aimed to create a

F1000Research, 2013 For the majority of organs in developing vertebrate embryos, left-right asymmetry is controlled by a ciliated region; the left-right organizer node in the mouse and human, and the Kuppfer’s vesicle in the zebrafish. In the zebrafish, laterality cues from

The genotype-phenotype relationship in multicellular pattern-generating models - the neglected role of pattern descriptors [PDF]
, 2009 Background: A deep understanding of what causes the phenotypic variation arising from biological patterning processes, cannot be claimed before we are able to recreate this variation by mathematical models capable of generating genotype-phenotype maps ...

Patterning, From Conifers to Consciousness: Turing’s Theory and Order From Fluctuations
Frontiers in Cell and Developmental Biology, 2022 This is a brief account of Turing’s ideas on biological pattern and the events that led to their wider acceptance by biologists as a valid way to investigate developmental pattern, and of the value of theory more generally in biology.

Spatiotemporal Patterns in a General Networked Hindmarsh-Rose Model
Frontiers in Physiology, 2022 Neuron modelling helps to understand the brain behavior through the interaction between neurons, but its mechanism remains unclear. In this paper, the spatiotemporal patterns is investigated in a general networked Hindmarsh-Rose (HR) model. The stability
