Homogeneous Permutations [PDF]
The Electronic Journal of Combinatorics, 2002 There are just five Fraïssé classes of permutations (apart from the trivial class of permutations of a singleton set); these are the identity permutations, reversing permutations, composites (in either order) of these two classes, and all permutations. The paper also discusses infinite generalisations of permutations, and the connection with Fraïssé's ...

Ecology and Evolution, 2021 Invasion by generalist tree species can cause biotic homogenization, and such community impoverishment is likely more important in rare forest types. We quantified changes in tree diversity within Carolinian (range in Central Hardwood Forest), central ...

Ecology and Evolution, 2016 While the upward shift of plant species has been observed on many alpine and nival summits, the reaction of the subalpine and lower alpine plant communities to the current warming and lower snow precipitation has been little investigated so far.

Journal of Manufacturing and Materials Processing, 2018 In this work, the microstructure, texture, phases, and microhardness of 45° printed (with respect to the build direction) homogenized, and hot isostatically pressed (HIP) cylindrical IN718 specimens are investigated.

Wave Polarization Control in Anisotropic Locally Resonant Materials
Applied Sciences, 2023 Elastic wave propagation in solids can be controlled and manipulated by properly designed metamaterials. In particular, polarization conversion can be obtained by using anisotropic materials.

Homogeneity and h -homogeneity
Topology and its Applications, 2013 A topological space \(X\) is \textit{homogeneous} if each of its points can be carried to any other via a homeomorphism of the space; \(X\) is \textit{\(h\)-homogeneous} if it is homeomorphic to each of its nonempty clopen subspaces. The author investigates conditions under which these two notions are related for zero-dimensional spaces. The first main

Creep of a C-S-H gel: a micromechanical approach
Anais da Academia Brasileira de Ciências, 2010 Both clays and calcium silicate hydrates(the main hydration products of Portland cements) exhibit a microstructure made up of lamellar particles. The microscopic mechanism responsible for the macroscopic creep of such materials is often described as the ...

Mathematics, 2023 We study reaction–diffusion systems with rapidly oscillating terms in the coefficients of equations and in the boundary conditions, in media with periodic obstacles. The non-linear terms of the equations only satisfy general dissipation conditions.

Subsampling and homogenization to investigate variability of composite material mechanical properties [PDF]
, 2012 This paper presents an innovative homogenization sampling technique applied to multiscale modelling of composite materials. The goal is to build efficiently statistical variability of mechanical properties at mesoscopic scale from the heterogeneous media
