The Anatomical Record, EarlyView.Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

Arab Journal of Mathematical Sciences, 2017 Let P≥3 be an integer and (Vn) denote Lucas sequence of the second kind defined by V0=2,V1=P, and Vn+1=PVn−Vn−1 for n≥1. In this study, when P is odd and w∈{10,14,15,21,30,35,42,70,210}, we solved the equation Vn=wx2∓1.

An Identity for Second Order Sequences Obeying the Same Recurrence Relation [PDF]
arXiv, 2019 We derive an identity connecting any two second-order linear recurrence sequences having the same recurrence relation but whose initial terms may be different. Binomial and ordinary summation identities arising from the identity are developed. Illustrative examples are drawn from Fibonacci, Fibonacci-Lucas, Pell, Pell-Lucas, Jacobsthal and Jacobsthal ...

Monocular visual servo control of a quadcopter for crossing windows, doors, and corridors
Asian Journal of Control, EarlyView.Abstract This paper proposes a sequential visual servo control scheme for quadcopters, where the main goal is to drive a quadcopter to a desired pose while crossing windows, doors, or corridors using only visual feedback. This control scheme is composed of two stages that act in sequence: the approaching and pose regulation phases.

Batteries &Supercaps, Accepted Article.Understanding degradation mechanisms in Li‐ion cells is essential for advancing fast‐charging technologies. One of the primary limitations of fast charging is the risk of lithium plating, driven by the negative electrode potential. In this study, a reference electrode was integrated into 30 mAh pouch cells to investigate aging under various charging ...

Australian medical imaging and world war one
Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 510-517, December 2022., 2022 World War One was a decisive moment in the development of the the radiography profession. This paper details the environment of that time, describes our professions soldier pioneers and their daily challenges. Abstract Twenty years after the birth of medical imaging from Röntgen's 1895 discovery, military authorities understood the advantage of ...
