A combined approach to Perrin and Padovan hybrid sequences [PDF]

open access: yesHeliyon, 2021
Recently, there has been huge interest to a new numeric set, which brings together three numerical systems: complex, hyperbolic and dual numbers, called as hybrid number.

Combinatorial Interpretation of Numbers in the Generalized Padovan Sequence and Some of Its Extensions

open access: yesAxioms, 2022
There is ongoing research into combinatorial methods and approaches for linear and recurrent sequences. Using the notion of a board defined for the Fibonacci sequence, this work introduces the Padovan sequence combinatorial approach.

On the bi-periodic Padovan sequences [PDF]

open access: yesMathematica Moravica, 2023
In this study, we define a new generalization of the Padovan numbers, which shall also be called the bi-periodic Padovan sequence. Also, we consider a generalized bi-periodic Padovan matrix sequence. Finally, we investigate the Binet formulas, generating

Striatal Nitric Oxide Activity Better Predicts Motor Disability Than Proto-Oncogenes. [PDF]

open access: yesEur J Neurosci
The figure summarizes the experimental design in which mice received a single intraperitoneal injection of saline, haloperidol, metoclopramide, or L‐NOARG at different doses. Extrapyramidal (EPS) side effects were assessed using the catalepsy test and the Rota‐rod test.

Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti-herbivore defenses, selection for qualitative toxins, and acceleration of plant-herbivore coevolution. [PDF]

open access: yesAm J Bot
Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

Proportion, Function, and Generation of Dual Receptor Lymphocytes. [PDF]

open access: yesJ Immunol Res
The specific immune response mechanisms of B cells and T cells are centered on the classic clonal selection theory, which posits that “a single lymphocyte expresses only one type of antigen receptor.” This mechanism is primarily achieved through V(D)J allelic exclusion rearrangement on germline chromosomes and rigorous self‐tolerance selection. However,

Genomic prediction models for morpho-phenological traits in durum wheat based on Vrn, Ppd, and Rht alleles. [PDF]

open access: yesPlant Genome
Abstract Genetic variations in vernalization (Vrn), photoperiod (Ppd), and reduced plant height (Rht) genes significantly influence durum wheat adaptability. However, the systematic integration of these functional alleles into genomic prediction (GP) models has been limited.

Some geometric properties of the Padovan vectors in Euclidean 3-space [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Padovan numbers were defined by Stewart (1996) in honor of the modern architect Richard Padovan (1935) and were first discovered in 1924 by Gerard Cordonnier.

The complex-type Padovan-p sequences [PDF]

open access: yesMathematica Moravica, 2022
In this paper, we define the complex-type Padovan-p sequence and then give the relationships between the Padovan-p numbers and the complex-type Padovan-p numbers.

Intersection of Padovan and Tribonacci sequences [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Assume that Tₙ is the n-th term of Tribonacci sequence and Pₘ is the m-th term of Padovan sequence. In this paper we solve the equation Tₙ=Pₘ completely.
