Topology and Signature Changes in Braneworlds [PDF]

Classical and Quantum Gravity, 2004
It has been believed that topology and signature change of the universe can only happen accompanied by singularities, in classical, or instantons, in quantum, gravity.

Fermi surface topology and signature of surface Dirac nodes in LaBi

Scientific Reports, 2017
Novel topological state of matter is one of the rapidly growing fields in condensed matter physics research in recent times. While these materials are fascinating from the aspect of fundamental physics of relativistic particles, their exotic transport ...

Topological isoconductance signatures in Majorana nanowires [PDF]

Scientific Reports, 2021
AbstractWe consider transport properties of a hybrid device composed by a quantum dot placed between normal and superconducting reservoirs, and coupled to a Majorana nanowire: a topological superconducting segment hosting Majorana bound states (MBSs) at the opposite ends.

Signatures of Topological Branched Covers [PDF]

International Mathematics Research Notices, 2020
Abstract Let $X^4$ and $Y^4$ be smooth manifolds and $f: X\to Y$ a branched cover with branching set $B$. Classically, if $B$ is smoothly embedded in $Y$, the signature $\sigma (X)$ can be computed from data about $Y$, $B$ and the local degrees of $f$. When $f$ is an irregular dihedral cover and $B\subset Y$ smoothly embedded away from a

Graphic Groups, Graph Homomorphisms, and Graphic Group Lattices in Asymmetric Topology Cryptography

Entropy, 2023
Using asymmetric topology cryptography to encrypt networks on the basis of topology coding is a new topic of cryptography, which consists of two major elements, i.e., topological structures and mathematical constraints.

Dualistic classification of high grade serous ovarian carcinoma has its root in spatial heterogeneity

Journal of Advanced Research, 2023
Introduction: Widespread intra-peritoneal metastases is a main feature of high grade serous ovarian carcinoma (HGSOC). Recently, the extent of tumour heterogeneity was used to evaluate the cancer genomes among multi-regions in HGSOC. However, there is no

Using the co-expression network of T cell-activation-related genes to assess the disease activity in Takayasu’s arteritis patients

Arthritis Research & Therapy, 2021
Background There have been lacking reliable serum biomarkers in assessing the disease activity of Takayasu’s arteritis (TAK). This study aimed to assess the disease activity of TAK by assayed gene expression levels in peripheral mononuclear cells (PBMCs).

Topological Signatures of Globular Polymers [PDF]

Physical Review Letters, 2011
Simulations in which a globular ring polymer with delocalized knots is separated in two interacting loops by a slipping link, or in two non-interacting globuli by a wall with a hole, show how the minimal crossing number of the knots controls the equilibrium statistics.
