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

Heliyon, 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. Motivated and based on the importance of this system, we apply the definition of hybrid numbers to Perrin numbers and introduce Perrin hybrid numbers and examine some properties of ...

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

Eur 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.

From the Americas to Southeast Asia: Navigating The Genomic Waves of Fall Armyworm (<i>Spodoptera frugiperda</i>) Invasions. [PDF]

Evol Appl
ABSTRACT The fall armyworm (FAW), scientifically known as Spodoptera frugiperda, is an agricultural pest native to the American continents. Its larvae display voracious feeding behavior with a host range of over 350 plant species. The pest was first detected outside the Americas in 2016, subsequently spreading across Africa, Asia, and Oceania.

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

J 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,

Contrasting patterns of population structure in two habitat-forming kelp species in southeastern Australia. [PDF]

J Phycol
Abstract The distribution and connectivity of species around the globe are changing at a rapid pace. Increasing sea temperatures are a driving factor of changes in temperate macroalgal distributions. Southeast Australia is considered a global ocean‐warming hotspot, where macroalgal populations are predicted to decline significantly by 2100.

Nematopsis Schneider, 1892 in Nerite Gastropods From Saint Kitts, With a Phylogenetic Study of the Genus, and Placement Within the Phylum Apicomplexa Levine, 1970. [PDF]

J Eukaryot Microbiol
ABSTRACT The Apicomplexa are obligate unicellular parasites found in terrestrial and aquatic environments. Nematopsis are found infecting marine invertebrates in a life cycle involving mollusks and crustaceans. In the present study, mantle and muscle tissues from nerite gastropods were microscopically examined for Nematopsis using wet mounts and ...

Tumor-related epilepsy in glioma: A multidisciplinary overview. [PDF]

Epilepsia
Abstract Seizures are a common and challenging symptom in brain tumors, affecting approximately 60% of patients. Tumor‐related epilepsy (TRE) in glioma patients requires personalized and dynamic management in a multidisciplinary environment, especially for its intricate pathophysiology and unpredictable disease evolution. This investigation provides an

On Hyperbolic Padovan and Hyperbolic Pell-Padovan Sequences

Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2022
In this article, we extend Padovan and Pell-Padovan numbers to Hyperbolic Padovan and Hyperbolic Pell-Padovan numbers, respectively. Moreover we obtain Binet-like formulas, generating functions and some identities related with Hyperbolic Padovan and Hyperbolic Pell-Padovan numbers.

The complex-type Padovan-p sequences

Mathematica 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. Also, we provide a new Binet formula and a new combinatorial representation of the complex-type Padovan-p numbers by the aid of the nth power of the generating matrix of the complex-type ...

Intersection of Padovan and Tribonacci sequences

Notes on Number Theory and Discrete Mathematics, 2023
Assume that T_{n} is the n-th term of Tribonacci sequence and P_{m} is the m-th term of Padovan sequence. In this paper we solve the equation T_{n}=P_{m} completely.
