Gravitational Radiation From Binary Systems With Time Varying Masses
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.

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.

On the sequences of $(q,k)$-generalized Fibonacci numbers [PDF]
We consider a new family of recurrence sequences, the $(q,k)$-generalized Fibonacci numbers. These sequences naturally extend the well-known sequences of $k$-generalized Fibonacci numbers and generalized $k$-order Pell numbers.

On Dual Quaternions with $k-$Generalized Leonardo Components
In this paper, we define a one-parameter generalization of Leonardo dual quaternions, namely $k-$generalized Leonardo-like dual quaternions. We introduce the properties of $k$-generalized Leonardo-like dual quaternions, including relations with Leonardo,

On Gaussian Jacobsthal-Padovan Numbers
Gaussian Jacobsthal-Padovan numbers have been the central focus of this paper and firstly this number sequence has defined. Later, we have given the proof of the generating function of the Gaussian Jacobsthal-Padovan sequence.

On a New Generalization of Pell Hybrid Numbers
In this paper, we define and study a new one-parameter generalization of the Pell hybrid numbers. Based on the definition of r-Pell numbers, we define the r-Pell hybrid numbers.

ABSTRACT Disorders of lipid metabolism contribute to the occurrence and progression of hematological malignancies, including chronic lymp hocytic leukemia (CLL). The objective of this study was to investigate the association between serum lipid levels and prognosis in patients with CLL.

In this article, we study a novel extension of the classic balancing numbers, referred to as the higher-order balancing numbers and denoted by. This sequence is analogous to the higher-order Fibonacci numbers and follows the same recurrence relation as ...

Birch Transpiration Is Not the Main Reason for Insufficient Water Levels in a Rewetted Bog
ABSTRACT Natural bogs have high water level (WL) that prevents peat decomposition and promotes bog‐specific vegetation. Especially in rewetted bogs, increasing tree encroachment is observed in combination with low WL. Simultaneously, a general shift in vegetation and microform distribution is visible.
