Hyperbolic Padovan Sequences

open access: yes, 2021
In this study, we define thehyperbolic Padovan numbers and we obtain recurrence relations and the summationformulas for these numbers. Firstly, wepresent some background information about Hyperbolic numbers and Padovannumbers.

Spectral Study of Five Major Impact Basins and Their Volcanic Infills on Mercury: A Window Into the Mantle's Properties

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
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.

BAZI FARK DENKLEMLERİNİN AYARLANMIŞ JACOBSTHAL-PADOVAN SAYILARI İLE İLİŞKİLİ TAM ÇÖZÜMLERİ

open access: yes, 2022
In this paper, we obtain the form of the solutions of some rational difference equations via adjusted Jacobsthal-Padovan numbers. We find a relation between the exact solutions and the adjusted Jacobsthal-Padovan numbers.

The Impact of a Long‐Lived Basal Magma Ocean on the Thermochemical Evolution of Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
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 ...

An Encoding-Decoding algorithm based on Padovan numbers

open access: yesCoRR, 2019
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.

A Study on Generalized Blaise Numbers

open access: yes, 2023
In this paper, we introduce and investigate the generalized Blaise sequences and we deal with, in detail, two special cases, namely, Blaise and Blaise-Lucas sequences.

Effects of Long‐Term Nutrient Addition on Leaf Metabolites, Herbivory, and Mycorrhizal Spores Associated With a Savannah Woody Species

open access: yesAustral Ecology, Volume 50, Issue 11, November 2025.
ABSTRACT Given the importance of soil conditions for ecosystem functioning, fertilisation experiments are a valuable tool for assessing how systems respond to changes in soil properties. However, the effects of changes in nutrient availability on multitrophic interactions in savannah ecosystems of the Brazilian Cerrado are still scarce. We investigated

The X -coordinates of Pell equations and Padovan numbers

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2019
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.

On the $x$--coordinates of Pell equations that are products of two Padovan numbers [PDF]

open access: yes, 2020
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-

HLA‐A*02:01 Presents Penicillin‐Modified Cysteinylated Peptides for T Cell Recognition

open access: yesAllergy, Volume 80, Issue 11, Page 3165-3177, November 2025.
We describe, for the first time, HLA presentation of benzylpenicillin‐modified peptides incorporating a cysteine‐benzylpenicillin conjugate (CysBP), disulfide linked to an in‐chain cysteine. A dominant HLA‐A*02:01 restricted benzylpenicillin‐specific T cell clone, TRAV3/TRBV20‐1 (BP‐TCR), was identified within PBMCs of a penicillin‐hypersensitive ...
