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

Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

open access: yesDeep Underground Science and Engineering, EarlyView.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...

Mental Health Conditions and Incident Cancer: A Prospective Cohort Study of 402,255 UK Biobank Participants

open access: yesInternational Journal of Cancer, EarlyView.
Evidence suggests a potential association between mental health conditions and cancer risk, yet previous studies were limited by small samples and the use of self‐reported measures. Using data from the UK Biobank's large‐scale prospective population cohort over a median follow‐up of 13.4 years, this analysis demonstrates associations between depression,

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.

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 ...

A Methodological Pathway for Supporting the Transition From Theory to Practice in Action‐Oriented Research for Transformative Change

open access: yesSustainable Development, EarlyView.
ABSTRACT Over recent decades, action‐oriented research has gained prominence in co‐producing actionable knowledge to drive transformative change toward sustainability. However, further methodological developments are needed to support the transition to the application phase of such knowledge.

On Some Relationships Among Pell, Pell-Lucas and Modified Pell Sequences

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2010
In this study, Pell, Pell-Lucas and Modified Pell numbers are investigated. Using Binet formulas for these sequences, some relations among these sequences are obtained. Also, some sum formulas are given by these properties.

Fermat and Mersenne numbers in $k$-Pell sequence

open access: yesМатематичні Студії, 2021
For an integer $k\geq 2$, let $(P_n^{(k)})_{n\geq 2-k}$ be the $k$-generalized Pell sequence, which starts with $0,\ldots,0,1$ ($k$ terms) and each term afterwards is defined by the recurrence $ P_n^{(k)}=2P_{n-1}^{(k)}+P_{n-2}^{(k)}+\cdots +P_{n-k}^{(k)}

Integrating multimodal data and machine learning for entrepreneurship research

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.

On the spectral norm of r-circulant matrices with the Pell and Pell-Lucas numbers

open access: yesJournal of Inequalities and Applications, 2016
Let us define A = C r ( a 0 , a 1 , … , a n − 1 ) $A=C_{r}(a_{0},a_{1},\ldots,a_{n-1})$ to be a n × n $n \times n$ r-circulant matrix. The entries in the first row of A = C r ( a 0 , a 1 , … , a n − 1 ) $A=C_{r}(a_{0},a_{1},\ldots,a_{n-1})$ are a i = P i
