On Mixed 𝐵-Concatenations of Pell and Pell–Lucas Numbers which are Pell Numbers

open access: yesMathematica Pannonica
Let (𝑃𝑛)𝑛≥0 and (𝑄𝑛)𝑛≥0 be the Pell and Pell–Lucas sequences. Let 𝑏 be a positive integer such that 𝑏 ≥ 2. In this paper, we prove that the following two Diophantine equations 𝑃𝑛 = 𝑏𝑑𝑃𝑚 + 𝑄𝑘 and 𝑃𝑛 = 𝑏𝑑𝑄𝑚 + 𝑃𝑘 with 𝑑, the number of digits of 𝑃𝑘 or 𝑄𝑘 in base 𝑏, have only finitely many solutions in nonnegative integers (𝑚, 𝑛, 𝑘, 𝑏, 𝑑).

Markov Triples with Generalized Pell Numbers

open access: yesMathematics, 2023
For an integer k≥2, let (Pn(k))n be the k-generalized Pell sequence which starts with 0,…,0,1 (k terms), and each term afterwards is given by Pn(k)=2Pn−1(k)+Pn−2(k)+⋯+Pn−k(k). In this paper, we determine all solutions of the Markov equation x2+y2+z2=3xyz,

Pell Leonardo numbers and their matrix representations

open access: yesJournal of New Results in Science
In this study, we investigate Pell numbers and Leonardo numbers and describe a new third-order number sequence entitled Pell Leonardo numbers. We then construct some identities, including the Binet formula, generating function, exponential generating ...

Pell Even Sum Cordial Labeling of Graphs

open access: yesRatio Mathematica, 2023
LetG=(V,E) be a simple graph and let P_i be Pell numbers. For a bijectionf:V\left(G\right)\rightarrow{P_0,\ P_1,\ldots,P_{\left|V\right|-1}}, assign the label 1 for the edge e=uv if f\left(u\right)+f(v) is even and label 0 otherwise. Then f is said to be

Almost neo cobalancing numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this work, we determined the general terms of almost neo cobalancing numbers, almost Lucas-neo cobalancing numbers and almost neo cobalancers in terms of cobalancing and Lucas-cobalancing numbers. We also deduced some results on relationship with Pell,

Prenatal exposure to antihypertensive medication: A systematic review of neurodevelopmental and educational outcomes

open access: yesJCPP Advances, EarlyView.
This systematic review investigated the association of prenatal exposure to antihypertensive medication with longer‐term poor neurodevelopmental outcomes by evaluating the findings from existing literature. We undertook a systematic review of previous studies looking specifically at neurodevelopmental outcomes in children.

A note on Pell-Padovan numbers and their connection with Fibonacci numbers

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2020
In this paper, we find new relations involving the Pell-Padovan sequence which arise as determinants of certain families of Toeplitz-Hessenberg matrices. These determinant formulas may be rewritten as identities involving sums of products of Pell-Padovan

When Does Top Management Team Diversity Matter in Large Organizations?

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...
