Reorganized brain functional network topology in stable and progressive mild cognitive impairment
Frontiers in Aging NeuroscienceAIMMild cognitive impairment (MCI) includes two distinct subtypes, namely progressive MCI (pMCI) and stable MCI (sMCI). The objective of this study was to identify the topological reorganization of brain functional networks in patients with pMCI and sMCI.

Pure Ideals in Residuated Lattices [PDF]
Transactions on Fuzzy Sets and Systems, 2022 Ideals in MV algebras are, by definition, kernels of homomorphism. An ideal is the dual of a filter in some special logical algebras but not in non-regular residuated lattices.

Topological pressures for𝜖-stable and stable sets [PDF]
Pacific Journal of Mathematics, 2013 Topological pressures of the preimages of $ $-stable sets and some certain closed subsets of stable sets in positive entropy systems are investigated. It is showed that the topological pressure of any topological system can be calculated in terms of the topological pressure of the preimages of $ $-stable sets. For the constructed closed subset of the

The equivariant topology of stable Kneser graphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 Schrijver introduced the stable Kneser graph $SG_{n,k}, n \geq 1, k \geq 0$. This graph is a vertex critical graph with chromatic number $k+2$, its vertices are certain subsets of a set of cardinality $m=2n+k$.

Open Mathematics, 2020 In this paper, by using the ideal theory in residuated lattices, we construct the prime and maximal spectra (Zariski topology), proving that the prime and maximal spectra are compact topological spaces, and in the case of De Morgan residuated lattices ...

Dynamically Stable Topological Phase of Arsenene [PDF]
Scientific Reports, 2019 AbstractFirst-principles calculations based on density functional theory (DFT) are used to investigate the electronic structures and topological phase transition of arsenene under tensile and compressive strains. Buckling in arsenene strongly depends on compressive/tensile strain.

Topologically stable equicontinuous non-autonomous systems
Filomat, 2021 We obtain sufficient conditions for commutative non-autonomous systems on certain metric spaces (not necessarily compact) to be topologically stable. In particular, we prove that: (i) Every mean equicontinuous, mean expansive system with strong average shadowing property is topologically stable.

Topological stable rank of nest algebras [PDF]
Proceedings of the London Mathematical Society, 2008 We establish a general result about extending a right invertible row over a Banach algebra to an invertible matrix. This is applied to the computation of right topological stable rank of a split exact sequence. We also introduce a quantitative measure of stable rank.

Active Equalization of Lithium-Ion Battery Based on Reconfigurable Topology
Applied Sciences, 2023 The equalization technique is a key technique in the secondary utilization of retired batteries. In this paper, a double-layer equalization method is proposed, which combines the reconfigurable topology with the converter active equalization method.

Convergence to a L\'evy process in the Skorohod $M_1$ and $M_2$ topologies for nonuniformly hyperbolic systems, including billiards with cusps [PDF]
, 2020 We prove convergence to a Levy process for a class of dispersing billiards with cusps. For such examples, convergence to a stable law was proved by Jung & Zhang.
