Remaking meaning through intersemiotic translation: the case of online medical journals

open access: yesJoSTrans: The Journal of Specialised Translation, 2022
The intersemiotic translation of written research abstracts is currently practised in online medical journals to facilitate experts' rapid access to specialised knowledge.

Effects of motion paradigm on human perception of tilt and translation

open access: yesScientific Reports, 2022
The effect of varying sinusoidal linear acceleration on perception of human motion was examined using 4 motion paradigms: off-vertical axis rotation, variable radius centrifugation, linear lateral translation, and rotation about an earth-horizontal axis.

The nuclei and other properties of p-primitive semifield planes

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
In this article the nuclei of p-primitive semifield planes are studied. The behavior of this class of planes under the operations of derivation, transposition and dualization is also analyzed.

A characterization of the desarguesian planes of order q2 by SL(2,q)

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1983
The main result is that if the translation complement of a translation plane of order q2 contains a group isomorphic to SL(2,q) and if the subgroups of order q are elations (shears), then the plane is Desarguesian. This generalizes earlier work of Walker,

Translation planes of even order in which the dimension has only one odd factor

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
Let G be an irreducible subgroup of the linear translation complement of a finite translation plane of order qd where q is a power of 2. GF(q) is in the kernel and d=2sr where r is an odd prime. A prime factor of |G| must divide (qd+1)∏i=1d(qi−1).

The geometry of GL(2,q) in translation planes of even order q2

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
In this article we show the following: Let π be a translation plane of even order q2 that admits GL(2,q) as a collineation group. Then π is either Desarguesian, Hall or Ott-Schaeffer.

Collineation groups of translation planes of small dimension

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
A subgroup of the linear translation complement of a translation plane is geometrically irreducible if it has no invariant lines or subplanes. A similar definition can be given for “geometrically primitive”.

Classification of space-like translation surfaces in the 3-dimensional Lorentz Heisenberg group H3 [PDF]

open access: yesArab Journal of Mathematical Sciences, 2023
Purpose – In the Lorentz Heisenberg space H3 endowed with flat metric g3, a translation surface is parametrized by r(x, y) = γ1(x)*γ2(y), where γ1 and γ2 are two planar curves lying in planes, which are not orthogonal.
