Dynamic Organization of Cells in Colonic Epithelium is Encoded by Five Biological Rules. [PDF]

open access: yesBiol Cell
This study reports that a set of five biological rules encodes how colonic epithelium dynamically maintains its precise organization of cells despite continuous tissue renewal. These rules might even provide a means to understand the mechanisms that underlie organization of other tissue types, and how tissue disorganization leads to birth defects and ...

On (k,p)-Fibonacci Numbers

open access: yesMathematics, 2021
In this paper, we introduce and study a new two-parameters generalization of the Fibonacci numbers, which generalizes Fibonacci numbers, Pell numbers, and Narayana numbers, simultaneously.

Altered Numbers of Fibonacci Number Squared

open access: yesJournal of New Theory, 2023
We investigate two types of altered Fibonacci numbers obtained by adding or subtracting a specific value $\{a\}$ from the square of the $n^{th}$ Fibonacci numbers $G^{(2)}_{F(n)}(a)$ and $H^{(2)}_{F(n)}(a)$.

The sequence of trifurcating Fibonacci numbers

open access: yesRatio Mathematica, 2021
One of the interesting generalizations of Fibonacci sequence is a k-Fibonacci sequence, which is further generalized into the ‘Bifurcating Fibonacci sequence’.

Some Algebraic Aspects of MorseCode Sequences [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Morse code sequences are very useful to give combinatorial interpretations of various properties of Fibonacci numbers. In this note we study some algebraic and combinatorial aspects of Morse code sequences and obtain several q-analogues of Fibonacci

Novel Fibonacci and non-Fibonacci structure in the sunflower: results of a citizen science experiment [PDF]

open access: yesRoyal Society Open Science, 2016
This citizen science study evaluates the occurrence of Fibonacci structure in the spirals of sunflower (Helianthus annuus) seedheads. This phenomenon has competing biomathematical explanations, and our core premise is that observation of both Fibonacci ...

On Fibonacci (k,p)-Numbers and Their Interpretations

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
In this paper, we define new kinds of Fibonacci numbers, which generalize both Fibonacci, Jacobsthal, Narayana numbers and Fibonacci p-numbers in the distance sense, using the definition of a distance between numbers by a recurrence relation according to

Bernoulli F-polynomials and Fibo–Bernoulli matrices

open access: yesAdvances in Difference Equations, 2019
In this article, we define the Euler–Fibonacci numbers, polynomials and their exponential generating function. Several relations are established involving the Bernoulli F-polynomials, the Euler–Fibonacci numbers and the Euler–Fibonacci polynomials. A new

Generating Functions of the Products of Bivariate Complex Fibonacci Polynomials with Gaussian Numbers and Polynomials

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2020
In this paper, we define and study the bivariate complex Fibonacci and Lucas polynomials. We introduce a operator in order to derive some new symmetric properties of bivariate complex Fibonacci and bivariate complex Lucas polynomials, and give the ...

On Special Spacelike Hybrid Numbers

open access: yesMathematics, 2020
Hybrid numbers are generalizations of complex, hyperbolic and dual numbers. A hyperbolic complex structure is frequently used in both pure mathematics and numerous areas of physics.
