Adaptive Protection Method of Distribution Networks Using the Sensitivity Analysis for Changed Network Topologies Based on Base Network Topology

open access: yesIEEE Access, 2020
This paper proposes an adaptive protection method using sensitivity analysis that examines the effect of changed network topologies (CNTs) on the operation time of protective devices (PDs) for a base network topology (BNT) in a distribution network.

Dynamic GCN: Context-enriched Topology Learning for Skeleton-based Action Recognition [PDF]

open access: yesACM Multimedia, 2020
raph Convolutional Networks (GCNs) have attracted increasing interests for the task of skeleton-based action recognition. The key lies in the design of the graph structure, which encodes skeleton topology information.

On the Transmission-Based Graph Topological Indices [PDF]

open access: yesKragujevac Journal of Mathematics, 2020
The distance $d(u,v)$ between the vertices $u$ and $v$ of a connected graph $G$ is defined as the number of edges in a minimal path connecting them. The \emph{transmission} of a vertex $v$ of $G$ is defined by $ (v)=\sum\limits_{u\in V(G)}{d(v,u)}$. In this article we aim to define some transmission-based topological indices. We obtain lower and upper

Etoposide‐induced cancer cell death: roles of mitochondrial VDAC1 and calpain, and resistance mechanisms

open access: yesMolecular Oncology, EarlyView.
The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Orderability and continuous selections for Wijsman and Vietoris hyperspaces

open access: yesApplied General Topology, 2003
Bertacchi and Costantini obtained some conditions equivalent to the existence of continuous selections for the Wijsman hyperspace of ultrametric Polish spaces. We introduce a new class of hypertopologies, the macro-topologies.

The interplay between weak topologies on topological semilattices [PDF]

open access: yesTopology Appl. 259 (2019), 134-154, 2018
We study the interplay between three weak topologies on a topological semilattice $X$: the weak$^\circ$ topology $\mathcal W^\circ_X$ (generated by the base consiting of open subsemilattices of $X$), the weak$^\bullet$ topology $\mathcal W^\bullet_X$ (generated by the subbase consisting of complements to closed subsemilattices), and the $\mathbb I ...

Vessel Axis Tracking Using Topology Constrained Surface Evolution

open access: yesIEEE Transactions on Medical Imaging, 2007
An approach to 3-D vessel axis tracking based on surface evolution is presented. The main idea is to guide the evolution of the surface by analyzing its skeleton topology during evolution, and imposing shape constraints on the topology.

Topology of the set of univoque bases

open access: yesTopology and its Applications, 2016
Abstract Given a positive integer M, a number q > 1 is called a univoque base if there is exactly one sequence ( c i ) = c 1 c 2 ⋯ with integer digits c i belonging to the set { 0 , 1 , … , M } , such that 1 = ∑ i = 1 ∞ c i q − i .

Molecular and functional profiling unravels targetable vulnerabilities in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
We used whole exome and RNA‐sequencing to profile divergent genomic and transcriptomic landscapes of microsatellite stable (MSS) and microsatellite instable (MSI) colorectal cancer. Alterations were classified using a computational score for integrative cancer variant annotation and prioritization.

Towards complete characterization of topological insulators and superconductors: A systematic construction of topological invariants based on Atiyah-Hirzebruch spectral sequence [PDF]

open access: yesarXiv, 2023
The past decade has witnessed significant progress in topological materials investigation. Symmetry-indicator theory and topological quantum chemistry provide an efficient scheme to diagnose topological phases from only partial information of wave functions without full knowledge of topological invariants, which has resulted in a recent comprehensive ...
