Closure results for arbitrarily partitionable graphs [PDF]

open access: yesOpuscula Mathematica
A well-known result of Bondy and Chvátal establishes that a graph of order \(n\) is Hamiltonian if and only if its \(n\)-closure (obtained through repeatedly adding an edge joining any two non-adjacent vertices with degree sum at least \(n\)) also is. In

Experiences of mine closure cover with geosynthetics in Peru [PDF]

open access: yesE3S Web of Conferences
Peru is internationally recognized as one of the countries with significant mining reserves. According to the Department of Energy and Mines (MINEM), as of December 2021, a total of 672 mining concession holders were registered and declared in the ...

Corrosion resistant coating with passive protection and self-healing property based on Fe3O4-MBT nanoparticles

open access: yesCorrosion Communications, 2022
This work synthesized novel Fe3O4 nanoparticles loaded with 2-mercaptobenzothiazole corrosion inhibitors (Fe3O4-MBT NPs), which possessed not only photothermal conversion property but also corrosion inhibition ability.

An approach to computing downward closures

open access: yes, 2015
The downward closure of a word language is the set of all (not necessarily contiguous) subwords of its members. It is well-known that the downward closure of any language is regular.

Sealing of Unconformity Structure and Hydrocarbon Accumulation in the Baikouquan Formation of the Mahu Sag

open access: yesApplied Sciences
Unconformity stratigraphic traps are widely developed in the Mahu Sag, on the northwestern margin of the Junggar Basin. It is of great significance for subsequent oil and gas exploration to explore the role of conglomerate accumulation mode and ...

A supersolutions perspective on hypercontractivity [PDF]

open access: yes, 2019
The purpose of this article is to expose an algebraic closure property of supersolutions to certain diffusion equations. This closure property quickly gives rise to a monotone quantity which generates a hypercontractivity inequality.

Approximation of holomorphic mappings on strongly pseudoconvex domains

open access: yes, 2009
Let D be a relatively compact strongly pseudoconvex domain in a Stein manifold, and let Y be a complex manifold. We prove that the set A(D,Y), consisting of all continuous maps from the closure of D to Y which are holomorphic in D, is a complex Banach ...

Deletion operations: closure properties [PDF]

open access: yesInternational Journal of Computer Mathematics, 1994
The paper studies some variants of deletion operations which generalize the left/right quotient of languages. The main emphasis is put on how these deletions can be expressed as a combination of other operations, and on closure properties of various language families under deletion.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
