Remote Sensing, 2017 Topology adaptive water boundary extraction from satellite images using parametric snakes remains challenging in the domain of image segmentation. This paper proposed a modified balloon snake (MB-Snake) method based on the balloon snake (B-Snake) method,

Monoids, their boundaries, fractals and C*-algebras
Topological Algebra and its Applications, 2020 In this note we establish some connections between the theory of self-similar fractals in the sense of John E. Hutchinson (cf. [3]), and the theory of boundary quotients of C*-algebras associated to monoids.

Ishibashi states, topological orders with boundaries and topological entanglement entropy. Part II. Cutting through the boundary [PDF]
Journal of High Energy Physics, 2019 Abstract We compute the entanglement entropy in a 2+1 dimensional topological order in the presence of gapped boundaries. Specifically, we consider entanglement cuts that cut through the boundaries. We argue that based on general considerations of the bulk- boundary correspondence, the “twisted characters” feature in the Renyi ...

Ishibashi states, topological orders with boundaries and topological entanglement entropy. Part I [PDF]
Journal of High Energy Physics, 2019 Abstract In this paper, we study gapped edges/interfaces in a 2+1 dimensional bosonic topological order and investigate how the topological entanglement entropy is sensitive to them. We present a detailed analysis of the Ishibashi states describing these edges/interfaces making use of the physics of anyon condensation in the ...

A Novel Mesh Quality Improvement Method for Boundary Elements
Journal of Applied Mathematics, 2012 In order to improve the boundary mesh quality while maintaining the essential characteristics of discrete surfaces, a new approach combining optimization-based smoothing and topology optimization is developed. The smoothing objective function is modified,

Infernal and exceptional edge modes: non-Hermitian topology beyond the skin effect
JPhys Materials, 2023 The classification of point gap topology in all local non-Hermitian (NH) symmetry classes has been recently established. However, many entries in the resulting periodic table have only been discussed in a formal setting and still lack a physical ...

Topological expansion and boundary conditions [PDF]
Journal of High Energy Physics, 2008 In this article, we compute the topological expansion of all possible mixed-traces in a hermitian two matrix model. In other words we give a recipe to compute the number of discrete surfaces of given genus, carrying an Ising model, and with all possible given boundary conditions.

A level-set-based topology optimisation of carpet cloaking devices with the boundary element method
Mechanical Engineering Journal, 2016 We investigate a topology optimisation based on the level set method for a design problem of carpet cloaking devices. In topology optimisation of carpet cloaking devices, we need to calculate the electromagnetic response in a semi-infinite domain. We use
