Objects generated by an arbitrary natural number. Part 4: New aspects [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
The set Set(n), generated by an arbitrary natural number n, was defined in [3]. There, and in [5, 6], some arithmetic functions and arithmetic operators of a modal and topological types are defined over the elements of Set(n).

Evidence for a critical leopard conservation stronghold from a large protected landscape on the island of Sri Lanka

open access: yesGlobal Ecology and Conservation, 2022
The decline and extirpation of large carnivore populations can lead to cascading effects in natural ecosystems. An understanding of large carnivore population densities, distribution and dynamics is therefore critical for developing effective ...
