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

An Encoding-Decoding algorithm based on Padovan numbers
In this paper, we propose a new of coding/decoding algorithm using Padovan Q-matrices. This method is based on blocked message matrices. an advantage of this method is that the encryption of each message matrix will use a different key and that will increase the security of the method.

Tiling Models for Palindromic and n‐Colored Compositions With 1 s and 3 s
In this work, we explore compositions of positive integers into parts consisting of 1 and 3 s, highlighting their close connection to the Narayana numbers. We also examine palindromic compositions of this type and introduce arithmetic functions that reflect their structural properties.

The complex-type k-Padovan sequences and their applications [PDF]
In this paper, we define the complex-type k-Padovan numbers and then give the relationships between the 1,k-1-bonacci numbers, the k -Padovan numbers and the complex-type k-Padovan numbers by matrix method.

On the $x$--coordinates of Pell equations that are products of two Padovan numbers [PDF]
Let $ \{P_{n}\}_{n\geq 0} $ be the sequence of Padovan numbers defined by $ P_0=0 $, $ P_1 = P_2=1$, and $ P_{n+3}= P_{n+1} +P_n$ for all $ n\geq 0 $. In this paper, we find all positive square-free integers $ d \ge 2$ such that the Pell equations $ x^2-

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow
Abstract With its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole of Venus has been expected to separate from the figure pole in response to mantle flow ...

The X -coordinates of Pell equations and Padovan numbers
Summary: In this paper, we show that there is at most one value of the positive integer \(X\) participating in the Pell equation \(X^2-dY^2=k\), where \(k\in\{\pm1,\pm4\}\), which is a Padovan number, with a few exceptions that we completely characterize.

Abstract NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging mission has revealed that about 27% of the surface of Mercury is covered by smooth plains, which are mostly volcanic in origin. These plains are mainly located in the northern hemisphere, as well as within and around major impact basins.

The Impact of a Long‐Lived Basal Magma Ocean on the Thermochemical Evolution of Mars
Abstract A basal magma ocean (BMO) has been suggested to form as a consequence of cumulate overturn following crystallization of an initial global magma ocean. As a consequence of enrichment in iron and heat‐producing elements (HPE), the BMO stabilizes gravitationally at the base of the planetary mantle, affecting the efficiency of mantle convection ...
