A note on chain‐based semi‐Heyting algebras

open access: yes, 2020
We determine the number of non-isomorphic semi-Heyting algebras on an n-element chain, where n is a positive integer, using a recursive method. We then prove that the numbers obtained agree with those determined in [1].

Perfect non-commuting graphs of matrices over chains

open access: yes, 2017
In this paper, we study the non-commuting graph [Formula: see text] of strictly upper triangular [Formula: see text] matrices over an [Formula: see text]-element chain [Formula: see text]. We prove that [Formula: see text] is a compact graph.

Finite element simulation of an embedded anchor chain

open access: yes, 2018
The embedded portion of a mooring line plays an important role for efficient and economic design of an overall mooring system. This paper presents a methodology for numerical simulation of the behaviour of an embedded anchor chain as it cuts through the ...

Flexibility within the middle ears of vertebrates [PDF]

open access: yes, 2013
Introduction and aims: Tympanic middle ears have evolved multiple times independently among vertebrates, and share common features. We review flexibility within tympanic middle ears and consider its physiological and clinical implications.
