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

Three new classes of binomial Fibonacci sums [PDF]

open access: yesTransactions on Combinatorics
In this paper, we introduce three new classes of binomial sums involving Fibonacci (Lucas) numbers and weighted binomial coefficients. One particular result is linked to a problem proposal recently published in the journal The Fibonacci Quarterly.

Construction of dual-generalized complex Fibonacci and Lucas quaternions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
The aim of this paper is to construct dual-generalized complex Fibonacci and Lucas quaternions. It examines the properties both as dual-generalized complex number and as quaternion. Additionally, general recurrence relations, Binet's formulas, Tagiuri's (

Mersenne k-Fibonacci numbers

open access: yesGlasnik Matematicki, 2016
Summary: For an integer \(k\geq 2\), let \((F_{n}^{(k)})_{n}\) be the \(k\)-Fibonacci sequence which starts with \(0,\ldots ,0,1\) (\(k\) terms) and each term afterwards is the sum of the \(k\) preceding terms. In this paper, we find all \(k\)-Fibonacci numbers which are Mersenne numbers, i.e., \(k\)-Fibonacci numbers that are equal to 1 less than a ...

Weak Disorder in Fibonacci Sequences

open access: yes, 2006
We study how weak disorder affects the growth of the Fibonacci series. We introduce a family of stochastic sequences that grow by the normal Fibonacci recursion with probability 1-epsilon, but follow a different recursion rule with a small probability ...

On the bounds for the spectral norms of geometric circulant matrices

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we define a geometric circulant matrix whose entries are the generalized Fibonacci numbers and hyperharmonic Fibonacci numbers. Then we give upper and lower bounds for the spectral norms of these matrices.

Generalized Compositions and Weighted Fibonacci Numbers [PDF]

open access: yes, 2010
In this paper we consider particular generalized compositions of a natural number with a given number of parts. Its number is a weighted polynomial coefficient.

Safety, Tolerability, and Pharmacokinetics of GMDTC for Cadmium Poisoning: A Randomized Phase 1a/1b Trial

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Cadmium exposure causes serious health consequences; however, there is no clinically approved antidote for cadmium poisoning. This Phase 1a/1b trial aimed to investigate safety, tolerability, and pharmacokinetics of Sodium (S)‐2‐(dithiocarboxylato((2S,3R,4R,5R)‐2,3,4,5,6‐pentahydroxyhexyl) amino)‐4‐(methylthio) butanoate (GMDTC), a novel chelating ...

Tur\'an Graphs, Stability Number, and Fibonacci Index

open access: yes, 2008
The Fibonacci index of a graph is the number of its stable sets. This parameter is widely studied and has applications in chemical graph theory. In this paper, we establish tight upper bounds for the Fibonacci index in terms of the stability number and ...
