Pattern formations and relaxation dynamics in non-equilibrium systems
… predator-prey systems characterized by nested pattern formations. We first consider a six species game in which spiral patterns spontaneously form within coarsening domains. Through a systematic investigation of relevant correlation functions, the interface width, and other quantities, we show …

Scavenger-Predator-Prey Model with Finite Resources
… investigates the role of predator-taxis in pattern formation within predator-prey systems, as documented in the paper ”Generalized Holling III Functional Response: role of predator-taxis on spatial patterns, 2023.” Through a combination of weakly nonlinear analysis and amplitude equations, …

Wrinkling Patterns on Curved Surface with Gradient Curvature under Compression
… work focuses on understanding the wrinkling patterns on a curved surface, i.e., tori and cones, with varying curvatures and global deformation. By tuning the geometry confine-ment and material properties, we can control the surface morphologies in these systems which can potentially be …

Endogenous short interfering RNAs that silence chalcone synthase result in pigment pattern formation on soybean seed coats
… demonstrate that CHS siRNAs result in pigment pattern formations on soybean seed coats. In addition, small RNA sequencing data from twenty-one samples in six different tissues including cotyledons, roots, stems, and leaves showed that CHS siRNA expression is limited to the yellow seed coats …

Generative morphologies of architectural organization in matter force field
… its own computational procedures. Topology formations, pattern formations within topological boundaries and aggregated topology formations are three main categories of form finding methods being explored throughout the thesis. The goal of this particular thesis is not to find ways to achieve …

A study of the effects of spatially localized time-delayed feedback schemes on spatio-temporal patterns
… a specific localized region of a system periodic patterns can be generated that are distinct from those observed when controlling the whole system. In this thesis, we present the results of two interconnected studies: 1) Spatio-temporal patterns emerging from spatially localized time-delayed …

Stochastic dynamics in spatially extended physical and biological systems
… effect of nonnormality on stochastic Turing patterns in reaction diffusion systems, and (3) the velocity statistics of edge dislocations in plastic deformation of crystalline material. In Part I, I present a new model for the origin of homochirality, the observed single-handedness of …

Non-Equilibrium Pattern Formation in Multi-Species Interacting Particle Systems
Non-equilibrium systems can form complex patterns in their steady states. Examples are systems consisting of self-propelled particles or systems consisting of particles driven away from equilibrium by external energy sources. In steady states, the interacting particles spontaneously organise into …

Collective behaviour of active particles with mean-field interaction
… thesis contributes to the nonlinear analysis of pattern formations and emergent collective behaviour by showing rigorously how a relatively simple phase-space extended non-gradient, nonlocal and nonlinear single species model can create multiple metastable higher-dimensional patterns. In the …
