GENERALIZED IDENTITIES OF BIVARIATE FIBONACCI AND BIVARIATE LUCAS POLYNOMIALS

Journal of Amasya University the Institute of Sciences and Technology, 2020
In this paper, we present generalized identities of bivariate Fibonacci polynomials and bivariate Lucas polynomials and related identities consisting even and odd terms. Binet’s formula will employ to obtain the identities.

The Hybrid Numbers of Padovan and Some Identities

Annales Mathematicae Silesianae, 2020
In this article, we will define Padovan’s hybrid numbers, based on the new noncommutative numbering system studied by Özdemir ([7]). Such a system that is a set involving complex, hyperbolic and dual numbers.

Gravitational Radiation From Binary Systems With Time Varying Masses

Annalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

Infection Incidence and Survival in Patients With Multiple Myeloma and Chronic Lymphocytic Leukaemia: A Growing Concern in the Era of Modern Therapies

eJHaem, Volume 7, Issue 4, August 2026.
ABSTRACT Introduction Patients with multiple myeloma (MM) and chronic lymphocytic leukaemia (CLL) are burdened by immunodeficiency due to treatment and underlying disease. Infection‐related mortality remains a significant concern for patients' overall survival (OS). Methods This Swedish, population‐based study examined incidence of infections and OS in

Evolutionary Theories of Emotion in Italian Psychophysiology: Reception, Critique, and Influence, 1880–1920

Journal of the History of the Behavioral Sciences, Volume 62, Issue 4, Fall 2026.
ABSTRACT This article examines how Italian psychophysiologists engaged with Charles Darwin's evolutionary theory of the emotions (ETE) between 1880 and 1920. Darwin's work on the natural history of emotions converged with a vibrant tradition of experimental psychophysiology that embodied Italian Positivism's scientific ambitions.

Floor and ceiling functions for Pell numbers [PDF]

Notes on Number Theory and Discrete Mathematics
The analytical study of the Pell number and the role of floor and ceiling functions into their computation is examined. Closed expressions of Pell numbers were initially derived using Binet's formula, followed by an asymptotic behavior study of the ...

Binet’s formula for operator-valued recursive sequences and the operator moment problem

Extracta Mathematicae
We derive a Binet-type formula for operator-valued sequences satisfying linear recurrence relations, extending the classical scalar case to the setting of bounded operators on Hilbert spaces.

Association Between Micronutrients and Cognitive Performance Among Adolescents and Young Adults Living With Sickle Cell Disease in Kumasi, Ghana: A Cross‐Sectional Study

eJHaem, Volume 7, Issue 3, June 2026.
ABSTRACT Aim Cognitive deficits are commonly reported in patients with sickle cell disease (SCD). Dietary micronutrient intake is a potential modifiable risk factor whose relationship with cognition in SCD patients remains poorly characterised. This study aimed to determine the association between dietary micronutrient intake and cognition among these ...

On some identities for the DGC Leonardo sequence [PDF]

Notes on Number Theory and Discrete Mathematics
In this study, we examine the Leonardo sequence with dual-generalized complex (DGC) coefficients for 𝔭∈ℝ. Firstly, we express some summation formulas related to the DGC Fibonacci, DGC Lucas, and DGC Leonardo sequences.

Relations between Generalized Bi-Periodic Fibonacci and Lucas Sequences

Mathematics, 2020
In this paper we consider a generalized bi-periodic Fibonacci {fn} and a generalized bi-periodic Lucas sequence {qn} which are respectively defined by f0=0, f1=1, fn=afn−1+cfn−2 (n is even) or fn=bfn−1+cfn−2 (n is odd), and q0=2d, q1=ad, qn=bqn−1+cqn−2 ...
