Trivializing and Orbifolding the Conifold's Base [PDF]
, 2007 The conifold is a cone over the space T^11, which is known to be topologically S^2xS^3. The coordinates used in the literature describe a sphere-bundle which can be proven to be topologically trivializable.

Topological Gradient-based Competitive Learning [PDF]
2021 International Joint Conference on Neural Networks (IJCNN), 2021 Topological learning is a wide research area aiming at uncovering the mutual spatial relationships between the elements of a set. Some of the most common and oldest approaches involve the use of unsupervised competitive neural networks. However, these methods are not based on gradient optimization which has been proven to provide striking results in ...

G3: Genes, Genomes, Genetics, 2016 Genomes evolve not only in base sequence but also in terms of their architecture, defined by gene organization and chromosome topology. Whereas genome sequence data inform us about the changes in base sequences for a large variety of organisms, the study

A New Analysis of the DS-CDMA Cellular Uplink Under Spatial Constraints [PDF]
, 2013 A new analysis is presented for the direct-sequence code-division multiple access (DS-CDMA) cellular uplink. For a given network topology, closed-form expressions are found for the outage probability and rate of each uplink in the presence of path ...

Simultaneous Material and Topology Optimization Based on Topological Derivatives [PDF]
, 2014 We use an asymptotic expansion of the compliance cost functional in linear elasticity to find the optimal material inside elliptic inclusions. We extend the proposed method to material optimization on the whole domain and compare the global quality of the solutions for different inclusion sizes.

Detecting Communities Based on Network Topology [PDF]
Scientific Reports, 2014 AbstractNetwork methods have had profound influence in many domains and disciplines in the past decade. Community structure is a very important property of complex networks, but the accurate definition of a community remains an open problem. Here we defined community based on three properties and then propose a simple and novel framework to detect ...

A Hybrid HVDC Topology Suitable for Large-Scale Pure Clean Energy Power Base Transmission
Zhongguo dianli, 2023 In order to meet the transmission needs of large-scale pure new energy power bases, after topology comparison, this paper used a hybrid cascaded topology consisting of a line commutated converter (LCC) and a modular multilevel converter (MMC) in the ...

Riesz bases of exponentials and the Bohr topology
Proceedings of the American Mathematical Society, 2021 We provide a necessary and sufficient condition to ensure that a multi-tile Ω ⊂ R d \Omega \subset \mathbb {R}^{d} of positive measure (but not necessarily bounded) admits a structured Riesz basis of exponentials for L

Analysis on the impact of router alias resolution
Tongxin xuebao, 2012 Router alias resolution is one of hard problems and important steps for router level Internet topology measurement based on traceroute mechanism,and the topology characteristic of the generated router level topology graph has close relationship with the ...

Pracì Mìžnarodnogo Geometričnogo Centru, 2015 The paper contains the results which describe the properties of such general topological construction as open extension topology. In particular, we prove that this topology is not transitive. We find the base of the least cardinality for the topology and
