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.

Extended Fibonacci Cubes [PDF]

open access: yesIEEE Transactions on Parallel and Distributed Systems, 1997
The Fibonacci cube (FC) is an interconnection network that possesses many desirable properties that are important in network design and application. However, most Fibonacci cubes (more than two third of all) are not Hamiltonian. In this paper, we propose a new network topology called extended Fibonacci cube (EFC/sub 1/) based on the same sequence F(i ...

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

open access: yesJournal 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

open access: yesMagnetic 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

Pauli Gaussian Fibonacci and Pauli Gaussian Lucas Quaternions

open access: yesMathematics, 2022
We have investigated new Pauli Fibonacci and Pauli Lucas quaternions by taking the components of these quaternions as Gaussian Fibonacci and Gaussian Lucas numbers, respectively. We have calculated some basic identities for these quaternions.

Mind the Gap: Linking Refactorings and Code Smells in Elixir

open access: yesJournal of Software: Evolution and Process, Volume 38, Issue 5, May 2026.
ABSTRACT Elixir is a functional programming language increasingly used in the industry to develop scalable and fault‐tolerant concurrent systems more easily and with fewer computational resources. In previous studies, we cataloged 35 code smells and 82 refactorings tailored for this language, validating them with over 300 experienced developers ...

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’.

An Exercise on Fibonacci Representations [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2001
Summary: We give a partial answer to a question of Carlitz asking for a closed formula for the number of distinct representations of an integer in the Fibonacci base.

Learnings from Approved Antibody‐Drug Conjugates: Clinical Pharmacology Perspectives

open access: yesThe 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.
