A Cubic Set Theoretical Approach to Linear Space

open access: yesAbstract and Applied Analysis, 2015
The main motivation of this paper is to introduce the notion of cubic linear space. This inspiration is received from the structure of cubic sets. The notions of R-intersection, R-union, P-intersection, and P-union of cubic linear spaces are defined and ...

Cubical sets and their site

open access: yesTheory and Applications of Categories, 2003
Even though cubical sets were there in the early work of Daniel Kan, simplicial sets have dominated since the contributions of Eilenberg and Zilber. Both combinatorial tools have their uses in algebraic topology and the passages between them need to be understood.

Parabolic and near-parabolic renormalizations for local degree three

open access: yes, 2020
The invariant class under parabolic and near-parabolic renormalizations constructed by Inou and Shishikura has been proved extremely useful in recent years. It leads to several important progresses on the dynamics of certain holomorphic maps with a local

Analysis of cubic permutation polynomials for turbo codes

open access: yes, 2012
Quadratic permutation polynomials (QPPs) have been widely studied and used as interleavers in turbo codes. However, less attention has been given to cubic permutation polynomials (CPPs).

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Novel Development to the Theory of Dombi Exponential Aggregation Operators in Neutrosophic Cubic Hesitant Fuzzy Sets: Applications to Solid Waste Disposal Site Selection

open access: yesComplexity, 2022
The neutrosophic cubic hesitant fuzzy set can efficiently handle the complex information in a decision-making problem because it combines the advantages of the neutrosophic cubic set and the hesitant fuzzy set.

Max-Leaves Spanning Tree is APX-hard for Cubic Graphs [PDF]

open access: yes, 2009
We consider the problem of finding a spanning tree with maximum number of leaves (MaxLeaf). A 2-approximation algorithm is known for this problem, and a 3/2-approximation algorithm when restricted to graphs where every vertex has degree 3 (cubic graphs).

Algebras of cubic matrices

open access: yes, 2016
We consider algebras of $m\times m\times m$-cubic matrices (with $m=1,2,\dots$). Since there are several kinds of multiplications of cubic matrices, one has to specify a multiplication first and then define an algebra of cubic matrices (ACM) with respect

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed
