Topological insulators based on HgTe [PDF]
Uspekhi Fizicheskih Nauk, 2019 Abstract The most interesting experimental results obtained in studies of 2D and 3D topological insulators (TIs) based on HgTe quantum wells and films are reviewed. In the case of 2D TIs, these include the observation of nonlocal ballistic and diffusion transport, the magnetic breakdown of 2D TIs, and an anomalous temperature dependence ...

A theory of bundles over posets [PDF]
, 2007 In algebraic quantum field theory the spacetime manifold is replaced by a suitable base for its topology ordered under inclusion. We explain how certain topological invariants of the manifold can be computed in terms of the base poset.

Topology-based signal separation
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2004 Traditional noise-filtering techniques are known to significantly alter features of chaotic data. In this paper, we present a noncausal topology-based filtering method for continuous-time dynamical systems that is effective in removing additive, uncorrelated noise from time-series data.

Topological groups with a bc-base [PDF]
Topology and its Applications, 2015 Approximately 10 years ago, Zambakhidze asked whether every non-zero-dimensional topological group with a bc-base is locally compact. Below we show that the small inductive dimension ind of any non-locally compact group with such a base doesn't exceed 1.

On The Stability Of Fixed Points In Topological Spaces
Journal of Kufa for Mathematics and Computer, 2014 In this papers we introduced new concepts of stability: strongly stable, c-stable, and c-strongly stable. We discussed the stability of fixed points with respect to each of a topology and a base for that topology.

The hyperspaces Cn(X) for finite ray-graphs
Applied General Topology, 2013 In this paper we consider the hyperspace Cn(X) of non-empty and closed subsets of a base space X with up to n connected components. The class of base spaces we consider we call finite ray-graphs, and are a noncompact variation on finite graphs.

Journal of Marine Science and Engineering, 2023 Ocean wireless sensor networks (OWSNs) play an important role in marine environment monitoring, underwater target tracking, and marine defense. OWSNs not only monitor the surface information in real time but also act as an important relay layer for ...

Isoskeletal Schiff base polynuclear coordination clusters: synthetic and theoretical aspects [PDF]
, 2016 This work addresses and enlightens synthetic aspects derived from our effort to systematically construct isoskeletal tetranuclear coordination clusters (CCs) of the general formula [TR2Ln2(LX)4(NO3)2(solv)2] possessing a specific defected dicubane ...

On the metrizability of spaces with a sharp base [PDF]
, 2001 A base $\mathcal{B}$ for a space $X$ is said to be sharp if, whenever $x\in X$ and $(B_n)_{n\in\omega}$ is a sequence of pairwise distinct elements of $\mathcal{B}$ each containing $x$, the collection $\{\bigcap_{j\le n}B_j:n\in\omega\}$ is a local base ...

Topology-based stereochemistry representation [PDF]
Comptes Rendus de l'Académie des Sciences - Series IIC - Chemistry, 1998 We propose to use combinarorial maps as a non-geometric computer representation of convex polyhedral and polygonal stereogenic entities. 'This model is simple, uniform, and general. It allows to represent any relative spatial arrangement of atoms (stereogenic entities, molecular shapes, etc.).
