Determinants and inverses of circulant matrices with complex Fibonacci numbers

Special Matrices, 2015
Let ℱn = circ (︀F*1 , F*2, . . . , F*n︀ be the n×n circulant matrix associated with complex Fibonacci numbers F*1, F*2, . . . , F*n. In the present paper we calculate the determinant of ℱn in terms of complex Fibonacci numbers.

Factorizations of the Fibonacci Infinite Word [PDF]

, 2015
The aim of this note is to survey the factorizations of the Fibonacci infinite word that make use of the Fibonacci words and other related words, and to show that all these factorizations can be easily derived in sequence starting from elementary ...

Perfect numbers and Fibonacci primes (I) [PDF]

International Journal of Number Theory, 2014
In this paper, we introduce the concept of F-perfect number, which is a positive integer n such that ∑d|n,d<n d2 = 3n. We prove that all the F-perfect numbers are of the form n = F2k-1 F2k+1, where both F2k-1 and F2k+1 are Fibonacci primes. Moreover, we obtain other interesting results and raise a new conjecture on perfect numbers.

Non‐Subtractive Arterial Spin Labeling‐Based (NSASL) Renal Magnetic Resonance Angiography (MRA): Development and Clinical Feasibility Evaluation

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1435-1447, May 2026.
ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.

Pole‐To‐Pole 3D Radial Trajectory Designs Improve Image Quality and Quantitative Parametric Mapping in the Brain and Heart

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2627-2643, May 2026.
ABSTRACT Purpose To design 3D radial spiral phyllotaxis trajectories aimed at removing phase inconsistencies, improving image quality, and enhancing parametric mapping accuracy by acquiring nearly opposing spokes starting from both hemispheres in 3D radial k‐space. Methods Two 3D radial trajectories, pole‐to‐pole and continuous spiral phyllotaxis, were

Some properties and extended Binet’s formula for the class of bifurcating Fibonacci sequence

Ratio Mathematica
One of the generalizations of Fibonacci sequence is a -Fibonacci sequence, which is further generalized in several other ways, some by conserving the initial conditions and others by conserving the related recurrence relation.

On the arrowhead-Fibonacci numbers

Open Mathematics, 2016
In this paper, we define the arrowhead-Fibonacci numbers by using the arrowhead matrix of the characteristic polynomial of the k-step Fibonacci sequence and then we give some of their properties.

Learnings from Approved Antibody‐Drug Conjugates: Clinical Pharmacology Perspectives

The Journal of Clinical Pharmacology, Volume 66, Issue 4, April 2026.
Abstract Over the past decade, antibody‐drug conjugates (ADCs) have emerged as promising anti‐cancer therapeutics, with twelve ADCs approved by the FDA. This review evaluates trends in these ADCs, stratified by payloads on doses studied from first‐in‐human (FIH) trials through approval and post‐marketing.
