Faber polynomial coefficient inequalities for bi-Bazilevič functions associated with the Fibonacci-number series and the square-root functions [PDF]

open access: goldJournal of Inequalities and Applications
Two new subclasses of the class of bi-Bazilevič functions, which are related to the Fibonacci-number series and the square-root functions, are introduced and studied in this article.

On the sum of a prime and a Fibonacci number [PDF]

open access: greenInternational Journal of Number Theory, 2010
We show that the set of the numbers that are the sum of a prime and a Fibonacci number has positive lower asymptotic density.

Tunable multichannel Fibonacci one-dimensional terahertz photonic crystal filter [PDF]

open access: yesScientific Reports, 2023
This paper proposes a multichannel terahertz optical filter based on a one-dimensional photonic crystal with a third-order Fibonacci structure, including a bulk Dirac semimetal.

The golden ratio in the pulmonary circulation in patients with heart failure and cardiogenic shock. [PDF]

open access: yesPhysiol Rep
Stroke volume is a determinant of both mPAP (left wireframe plot) and PP (right surface plot). Mean pulmonary artery pressure changes with SV with a coefficient of (PVR/t, where t = cardiac interval). The mPAP plot is based on a PVR of 4.2WU (or 0.252 mmHg/mL.s) at cardiac intervals from 400 to 1000 ms and PAWP of 29 mmHg.

Global warming and obesity: External heat exposure as a modulator of energy balance. [PDF]

open access: yesFASEB Bioadv
Core body temperature regulation can significantly influence metabolic processes to maintain energy balance. For example, geographic and environmental factors (global warming) can affect obesity rates and can be tracked along latitudinal boundaries.

Statistics on restricted Fibonacci words [PDF]

open access: yesTransactions on Combinatorics, 2021
We study two foremost Mahonian statistics, the major index and the inversion number for a class of binary words called restricted Fibonacci words. The language of restricted Fibonacci words satisfies recurrences which allow for the calculation of the ...

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 $H^{(2)}_{F(n)}(a)$.

A Class of Fibonacci Matrices, Graphs, and Games

open access: yesMathematics, 2022
In this paper, we define a class of Fibonacci graphs as graphs whose adjacency matrices are obtained by alternating binary Fibonacci words. We show that Fibonacci graphs are close in size to Turán graphs and that their size-stability tradeoff defined as ...

On Fibonacci functions with Fibonacci numbers [PDF]

open access: yesAdvances in Difference Equations, 2012
Abstract In this paper we consider Fibonacci functions on the real numbers R, i.e., functions f : R → R such that for all x ∈ R ,

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 ...
