The Representation and Finite Sums of the Padovan-p Jacobsthal Numbers

open access: yes, 2021
In this paper, we regard the Padovan-p Jacobsthal sequence and then we discuss the connection of the Padovan-p Jacobsthal numbers and Jacobsthal numbers. Furthermore, we give the permanental, determinantal, combinatorial, and exponential representations,

Influences of plant maternal effects, chemotype, and environment on the leaf bacterial community

open access: yesPlant Biology, Volume 27, Issue 5, Page 903-912, August 2025.
Plant maternal effects and growth environment, rather than terpenoid chemotype, determine the leaf microbial community of Tanacetum vulgare, but specific terpenoids are correlated with the abundance of certain bacteria. Abstract Plant individuals within a species can differ markedly in their leaf chemical composition, forming so‐called chemotypes ...

The Influence of Interior Structure and Thermal State on Impact Melt Generation Upon Large Impacts Onto Terrestrial Planets

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

The (s; t)-Padovan Quaternions Matrix Sequence

open access: yes, 2020
In this paper, we will introduce the (s; t)-Padovan quaternionsmatrix sequence. Starting the studies based on the generalization of thePadovan quaternion coefficients in relation to their recurrence, their matrixsequence is then defined.

Padovan-like sequences and generalized Pascal’s triangles

open access: yes, 2020
The Padovan sequence and the Plastic number are mathematical objects of central interest among architects, and from this point of view, their importance is com- parable to that of the Fibonacci sequence and the Golden mean.

La Secuencia de Padovan y el número plástico: um análisis prévio ya priori [PDF]

open access: yes, 2019
O presente trabalho apresenta as duas fases iniciais da Engenharia Didática com o tema envolvendo o estudo da Sequência de Padovan e o número plástico o qual foi objeto de estudo primordialmente por Richard Padovan (1935-?) e Gérard Cordonnier (1907 ...

Padovan, Perrin and Pell-Padovan Dual Quaternions

open access: yes, 2023
In this present study, we intend to determine the Padovan, Perrin and Pell-Padovan dual quaternions with nonnegative and negative subscripts. In line with this purpose, we construct some new properties such as; special determinant equalities, new ...
