Entanglement entropy and edge modes in topological string theory. Part I. Generalized entropy for closed strings

Journal of High Energy Physics, 2021
Progress in identifying the bulk microstate interpretation of the Ryu-Takayanagi formula requires understanding how to define entanglement entropy in the bulk closed string theory.

Counting cases in substitope algorithms [PDF]

, 2004
We describe how to count the cases that arise in a family of visualization techniques, including Marching Cubes, Sweeping Simplices, Contour Meshing, Interval Volumes, and Separating Surfaces.

Multi-trace correlators from permutations as moduli space

Journal of High Energy Physics, 2019
We study the n-point functions of scalar multi-trace operators in the U(N c ) gauge theory with adjacent scalars, such as N $$ \mathcal{N} $$ = 4 super Yang-Mills, at tree-level by using finite group methods.

Klein Topological Field Theories from Group Representations [PDF]

, 2011
We show that any complex (respectively real) representation of finite group naturally generates a open-closed (respectively Klein) topological field theory over complex numbers.

Groups with finitely many conjugacy classes and their automorphisms [PDF]

, 2009
We combine classical methods of combinatorial group theory with the theory of small cancellation over relatively hyperbolic groups to construct finitely generated torsion-free groups that have only finitely many classes of conjugate elements.

Altered functional network topology properties to detect anxiety and depression caused by Crohn’s disease and disease severity

Brain Research Bulletin
Objective: Here we investigated changes in topological properties of functional brain networks among individuals with Crohn’s disease (CD) and to determine whether these changes are related to CD severity, as well as CD-associated anxiety and depression,

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
