$k$-generalized Pell numbers which are repdigits in base $b$

Turkish Journal of Mathematics, 2022
Summary: Let \(k \geq 2\) be an integer and let \((P_n^{(k)})_{n \geq 2-k}\) be the \(k\)-generalized Pell sequence defined by \[ P_n^{(k)} = 2P_{n-1}^{(k)} + P_{n-2}^{(k)}+{\dots}+P_{n-k}^{(k)} \] for \(n\geq 2\) with initial conditions \[ P_{-(k-2)}^{(k)} = P_{-(k-3)}^{(k)} = \cdots =P_{-1}^{(k)} = P_0^{(k)} = 0, P_1^{(k)} = 1.

A New Generalization of Pell-Lucas Numbers (Bi-Periodic Pell-Lucas Sequence)

Communications in Mathematics and Applications, 2019
In this study, we bring into light, a new generalization of the Jacobsthal Lucas numbers, which shall also be called the bi-periodic Jacobsthal Lucas sequence as \begin{align*} Q_{n}= \begin{cases} 2bQ_{n-1}+Q_{n-2},&\text{if} \ n \ \text{is even} \\ 2aQ_{n-1}+Q_{n-2},&\text{if} \ n \ \text{is odd}% \end{cases} \text{\ \ }n\geq 2, \end{align*} with ...

Adaptive Spaces and Rural Futures: Climate Change, Agrarian Dynamics, and Knowledge Politics in Southeast Asian Socioecological Transformations

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Contemporary rural change in Southeast Asia is shaped by complex, intersecting forces that defy simplistic narratives. Researchers must therefore develop new ways to grasp nuanced, non‐linear, and locally specific processes to understand how transformational shifts may occur (or not) in the region.

Learning gains from work placements: Innovative behavior and the role of emotional competencies

European Management Review, EarlyView.
Abstract The importance of innovative behavior (IB) has been well documented, and the engagement of employees in IB has become a tacit norm in many organizations. It has also been understood that IB is emotionally charged. However, little research has concentrated on whether higher education (HE) providers can foster IB in university students, and ...

Incomplete Bivariate Fibonacci and Lucas -Polynomials [PDF]

, 2012
We define the incomplete bivariate Fibonacci and Lucas -polynomials. In the case =1, =1, we obtain the incomplete Fibonacci and Lucas -numbers. If =2, =1, we have the incomplete Pell and Pell-Lucas -numbers.

Fine‐scale genetic structure in co‐operatively breeding Palmchats (Dulus dominicus) suggests mixed kinship in compound nests

Ibis, EarlyView.
Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

On the Characteristic Polynomial of the Generalized k-Distance Tribonacci Sequences

, 2020
In 2008, I. Włoch introduced a new generalization of Pell numbers. She used special initial conditions so that this sequence describes the total number of special families of subsets of the set of n integers.

Interpreting the Intensity of Vocal Emotions Across Cultures

Scandinavian Journal of Psychology, EarlyView.
ABSTRACT Intensity is a fundamental dimension of emotions that affects their perception. However, theoretical and empirical studies on intensity, particularly in the vocal domain, remain limited. Furthermore, research on the effects of emotional dimensions (e.g., arousal, valence, and basicness) on intensity ratings remains sparse.
