Bounded sets in topological groups [PDF]
, 2010 A boundedness structure (bornology) on a topological space is an ideal of subsets containing all singletons, that is, closed under taking subsets and unions of finitely many elements.

Galois orbits of TQFTs: symmetries and unitarity
Journal of High Energy Physics, 2022 We study Galois actions on 2+1D topological quantum field theories (TQFTs), characterizing their interplay with theory factorization, gauging, the structure of gapped boundaries and dualities, 0-form symmetries, 1-form symmetries, and 2-groups.

Impact of Variable Speed on Collective Movement of Animal Groups
Frontiers in Physics, 2021 The collective dynamics and structure of animal groups has attracted the attention of scientists across a broad range of fields. A variety of agent-based models have been developed to help understand the emergence of coordinated collective behavior from ...

Understanding crowd-powered search groups: a social network perspective. [PDF]
PLoS ONE, 2012 BackgroundCrowd-powered search is a new form of search and problem solving scheme that involves collaboration among a potentially large number of voluntary Web users. Human flesh search (HFS), a particular form of crowd-powered search originated in China,

The evolutionary dynamics of protein-protein interaction networks inferred from the reconstruction of ancient networks. [PDF]
PLoS ONE, 2013 Cellular functions are based on the complex interplay of proteins, therefore the structure and dynamics of these protein-protein interaction (PPI) networks are the key to the functional understanding of cells.

Remarks on quiver gauge theories from open topological string theory [PDF]
, 2010 We study effective quiver gauge theories arising from a stack of D3-branes on certain Calabi-Yau singularities. Our point of view is a first principle approach via open topological string theory.

Anomaly matching in the symmetry broken phase: Domain walls, CPT, and the Smith isomorphism
SciPost Physics, 2020 Symmetries in Quantum Field Theory may have 't Hooft anomalies. If the symmetry is unbroken in the vacuum, the anomaly implies a nontrivial low-energy limit, such as gapless modes or a topological field theory. If the symmetry is spontaneously broken,
