The Arrangement of the Osteons and Kepler’s Conjecture

open access: yesApplied Sciences, 2023
The studies of bone tissue have mainly highlighted the morphometrical characteristics of the osteons, rather than their spatial distribution. This work aimed to verify if the topographical distribution of the osteons responds to geometrical order.

Does Time Smoothen Space? Implications for Space-Time Representation

open access: yesISPRS International Journal of Geo-Information, 2023
The continuous nature of space and time is a fundamental tenet of many scientific endeavors. That digital representation imposes granularity is well recognized, but whether it is possible to address space completely remains unanswered.

Enumeration and investigation of acute 0/1-simplices modulo the action of the hyperoctahedral group

open access: yesSpecial Matrices, 2017
The convex hull of n + 1 affinely independent vertices of the unit n-cube In is called a 0/1-simplex. It is nonobtuse if none its dihedral angles is obtuse, and acute if additionally none of them is right.
