A NOTE ON BIGAUSSIAN PELL AND PELL-LUCAS NUMBERS

Journal of Science and Arts, 2021
In this study, we define a new type of Pell and Pell-Lucas numbers which are called biGaussian Pell and biGaussian Pell-Lucas numbers. We also give the relationship between negabiGaussian Pell and Pell-Lucas numbers and bicomplex Pell and Pell-Lucas numbers.

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.

Three Diophantine equations concerning the polygonal numbers [PDF]

Notes on Number Theory and Discrete Mathematics
Many authors investigated the problem about the linear combination of two polygonal numbers being a perfect square, i.e., the Diophantine equation mPₖ(x)+nPₖ(y)=z², where Pₖ(x) denotes the x-th k-polygonal number and m, n are positive integers.

Gaussian-bihyperbolic Numbers Containing Pell and Pell-Lucas Numbers

Journal of Advanced Research in Natural and Applied Sciences, 2023
In this study, we define a new type of Pell and Pell-Lucas numbers which are called Gaussian-bihyperbolic Pell and Pell-Lucas numbers. We also define negaGaussian-bihyperbolic Pell and Pell-Lucas numbers. Moreover, we obtain Binet’s formulas, generating function formulas, d’Ocagne’s identities, Catalan’s identities, Cassini’s identities and some sum ...

Association of Maxillofacial Fractures With Demographic and Dental Factors: The Roles of Edentulism, Posterior Occlusion, Canines, and Lower Third Molar

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim This retrospective, two‐center study aims to improve understanding of fracture pathogenesis in maxillofacial trauma by examining variations related to sex, age, dental status, posterior occlusion, and the presence of lower third molars (LTM) and lower canines.

Incomplete Bivariate Fibonacci and Lucas 𝑝-Polynomials

Discrete Dynamics in Nature and Society, 2012
We define the incomplete bivariate Fibonacci and Lucas 𝑝-polynomials. In the case 𝑥=1, 𝑦=1, we obtain the incomplete Fibonacci and Lucas 𝑝-numbers. If 𝑥=2, 𝑦=1, we have the incomplete Pell and Pell-Lucas 𝑝-numbers.

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 ...

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.
