An application of gauge theory to four-dimensional topology
, 1983 Soit X une u-variete compacte reguliere simplement connexe orientee avec la propriete que la forme associee Q est definie positive. Alors cette forme est equivalente, sur les entiers, a la forme diagonale standard, soit dans une base: Q(u 1 ,u 2 ,...u 2 )

Topology and prediction of RNA pseudoknots
Bioinform., 2011 MOTIVATION Several dynamic programming algorithms for predicting RNA structures with pseudoknots have been proposed that differ dramatically from one another in the classes of structures considered.

Topological-insulator-based terahertz modulator [PDF]
Scientific Reports, 2017 AbstractThree dimensional topological insulators, as a new phase of quantum matters, are characterized by an insulating gap in the bulk and a metallic state on the surface. Particularly, most of the topological insulators have narrow band gaps, and hence have promising applications in the area of terahertz optoelectronics.

Some Results on Soft Multi Topology
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2013 In this article, at first we recall the concept of soft multiset. Then some results which we obtained on soft multisets were given. Moreover, in this paper, the notion of soft multi topology was introduced and some results on soft multi topology and the ...

On the Transmission-Based Graph Topological Indices [PDF]
Kragujevac 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 $σ(v)=\sum\limits_{u\in V(G)}{d(v,u)}$. In this article we aim to define some transmission-based topological indices.

Topology optimization for elastic base under rectangular plate subjected to moving load
Archives of Control Sciences, 2015 Distribution optimization of elastic material under elastic isotropic rectangular thin plate subjected to concentrated moving load is investigated in the present paper. The aim of optimization is to damp its vibrations in finite (fixed) time.

Evaluation model for topology partition base on simulation run time
Tongxin xuebao, 2013 Firstly,by analyzing the PDES mechanism,a variety of factors affecting simulation performance were summa-rized and classified,and the factor set influenced by topology partition result was found out; and then,by analyzing simulation run time,an ...

IEEE 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.

Motivic homotopy theory of group scheme actions
, 2015 We define an unstable equivariant motivic homotopy category for an algebraic group over a Noetherian base scheme. We show that equivariant algebraic $K$-theory is representable in the resulting homotopy category.
