On triangular matroids induced by n3-configurations
Open Mathematics, 2020 A triangular matroid is a rank-3 matroid whose ground set consists of the points of an n3{n}_{3}-configuration and whose bases are the point triples corresponding to non-triangles within the configuration.

Morley’s triangles of a triangle in the isotropic plane
Journal of GeometryMorley's trisector theorem is one of the most intriguing results of elementary triangle geometry. Adjacent trisectors of interior triangle angles intersect in three points of an equilateral triangle. Taking into account the ambiguity when considering angle trisectors of pairs of lines one can extend this result to a more complete picture with 18 ...

The Multiple Sclerosis Severity Allele rs10191329A and Cognitive Function: A UK Biobank Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT The genome‐wide association study of Multiple Sclerosis severity linked the genetic variant rs10191329A to long‐term disability and implicated brain resilience as a determinant of outcome. We hypothesised that rs10191329A might influence cognition in other neurological diseases and healthy controls.

Duality and Dimensionality Reduction Discrete Line Generation Algorithm for a Triangular Grid
ISPRS International Journal of Geo-Information, 2018 Vectors are a key type of geospatial data, and their discretization, which involves solving the problem of generating a discrete line, is particularly important. In this study, we propose a method for constructing a discrete line mathematical model for a

Triangles II: Complex triangle coordinates
Aequationes Mathematicae, 1996 This is the second in a series of three papers examining Euclidean triangle geometry via complex cross ratios [for part I see ibid., No. 1-2, 30-54 (1996; see the paper above)]. In this paper the author introduces complex triangle coordinates in the Euclidean plane using cross ratios, and uses them to prove theorems about triangles. She then develops a

Arthritis Care &Research, EarlyView.Objective Cam morphology, which is a significant risk factor for hip osteoarthritis, is commonly quantified by the alpha angle (AA). This study aims to explore the potential of the triangular index ratio (TIR) to quantify cam morphology on anteroposterior radiographs by assessing the association between TIR‐defined cam morphology and the development of

DETERMINATION OF THE DISTANCE BETWEEN THE ADDITIONAL POINT AND GEOREFERENCED GPS STANDPOINT
Rudarsko-geološko-naftni Zbornik, 1993 Determinating distances in unacceptable conditions from the georeferenced standing-place to some inaccessible point is performed by measuring the asimuth in the simulated triangle with the presumed base (the paper is published in Croatian).

Triangles III: Complex triangle functions
Aequationes Mathematicae, 1997 This is the third in a series of three papers that examine Euclidean geometry via complex cross-ratios. The first two papers [ibid. 52, No. 1-2, 30-54 (1996; Zbl 0860.51009); ibid., No. 3, 215-245 (1996; Zbl 0860.51010)] considered triangle shapes and triangle coordinates.
