On Generalized Fibonacci Numbers
Fibonacci numbers and their polynomials have been generalized mainly by two ways: by maintaining the recurrence relation and varying the initial conditions, and by varying the recurrence relation and maintaining the initial conditions. In this paper, we

On Quaternion-Gaussian Fibonacci Numbers and Their Properties
We study properties of Gaussian Fibonacci numbers. We start with some basic identities. Thereafter, we focus on properties of the quaternions that accept gaussian Fibonacci numbers as coefficients.

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

2-Fibonacci polynomials in the family of Fibonacci numbers [PDF]
In the present study, we define new 2-Fibonacci polynomials by using terms of a new family of Fibonacci numbers given in [4]. We show that there is a relationship between the coefficient of the 2-Fibonacci polynomials and Pascal’s triangle.

Restricted Permutations, Fibonacci Numbers, and k-generalized Fibonacci Numbers
A permutation $ \in S_n$ is said to {\it avoid} a permutation $ \in S_k$ whenever $ $ contains no subsequence with all of the same pairwise comparisons as $ $. For any set $R$ of permutations, we write $S_n(R)$ to denote the set of permutations in $S_n$ which avoid every permutation in $R$. In 1985 Simion and Schmidt showed that $|S_n(132, 213, 123)

Kin Competition Drives the Evolution of Earlier Metamorphosis. [PDF]
We develop a mathematical model to investigate how kin selection shapes the optimal timing of metamorphosis. We consider the full range of larval competition intensities and the full range of relatedness coefficients. This yields testable predictions as to how kin selection modulates the timing of metamorphosis.

On Bicomplex Fibonacci Numbers and Their Generalization
In this chapter, we consider bicomplex numbers with coefficients from Fibonacci sequence and give some identities. Moreover, we demonstrate the accuracy of such identities by taking advantage of idempotent representations of the bicomplex numbers. And then by this representation, we give some identities containing these numbers.

Restricted Permutations, Fibonacci Numbers, and k-generalized Fibonacci Numbers [PDF]
In 1985 Simion and Schmidt showed that the number of permutations in Sn which avoid 132, 213, and 123 is equal to the Fibonacci number Fn+1. We use generating function and bijective techniques to give other sets of pattern-avoiding permutations which can be enumerated in terms of Fibonacci or k-generalized Fibonacci numbers.

The Fibonacci numbers of certain subgraphs of circulant graphs
The Fibonacci number ℱ(G) of a graph G with vertex set V(G), is the total number of independent vertex sets S⊂V(G); recall that a set S⊂V(G) is said to be independent whenever for every two different vertices u,v∈S there is no edge between them.

The p-Frobenius and p-Sylvester numbers for Fibonacci and Lucas triplets. [PDF]
In this paper we study a certain kind of generalized linear Diophantine problem of Frobenius. Let $ a_1, a_2, \dots, a_l $ be positive integers such that their greatest common divisor is one.
