Abnormal Dynamic Functional Connectivity in Patients With End-Stage Renal Disease

Frontiers in Neuroscience, 2022
Dynamic functional connectivity (FC) analysis can capture time-varying properties of connectivity; however, studies focusing on dynamic FC in patients with end-stage renal disease (ESRD) are very limited.

From Hopf algebras to topological quantum groups. A short history, various aspects and some problems [PDF]

Banach Center Publications, 2020
Quantum groups have been studied within several areas of mathematics and mathematical physics. This has led to different approaches, each of them with their own techniques and conventions. Starting with Hopf algebras, where there is a general consensus, moving in the direction of topological quantum groups, where there is no such consensus, it is easy ...

Topological Field Theory and Quantum Holonomy Representations of Motion Groups

, 1999
Canonical quantization of abelian BF-type topological field theory coupled to extended sources on generic d-dimensional manifolds and with curved line bundles is studied.

Locally Quasi-Convex Compatible Topologies on a Topological Group

Axioms, 2015
For a locally quasi-convex topological abelian group (G,τ), we study the poset \(\mathscr{C}(G,τ)\) of all locally quasi-convex topologies on (G) that are compatible with (τ) (i.e., have the same dual as (G,τ) ordered by inclusion.

Holographic Chern-Simons Theories

, 2014
Chern-Simons theories in three dimensions are topological field theories that may have a holographic interpretation for suitable chosen gauge groups and boundary conditions on the fields.

Theta-terms in nonlinear sigma-models [PDF]

, 1999
We trace the origin of theta-terms in non-linear sigma-models as a nonperturbative anomaly of current algebras. The non-linear sigma-models emerge as a low energy limit of fermionic sigma-models.

Topological Study of Global Quantization in Non-Abelian Gauge Theories

, 1993
We study some topological aspects of non-abelian gauge theories intimately connected to the Lie algebras of the gauge groups and the homotopy theory in the generalized gauge orbit space.

Ambiguity in Social Network Data for Presence, Sensitive-Attribute, Degree and Relationship Privacy Protection. [PDF]

PLoS ONE, 2015
Maintaining privacy in network data publishing is a major challenge. This is because known characteristics of individuals can be used to extract new information about them.

Topological data analysis of monopole current networks in $U(1)$ lattice gauge theory

SciPost Physics
In $4$-dimensional pure compact $U(1)$ lattice gauge theory, we analyse topological aspects of the dynamics of monopoles across the deconfinement phase transition. We do this using tools from Topological Data Analysis (TDA).
