Floor and ceiling functions for Pell numbers [PDF]
Notes on Number Theory and Discrete MathematicsThe 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 ...

Guided Toward Equity: Communities of Practice and Organizational Change in Community Colleges
New Directions for Community Colleges, EarlyView.ABSTRACT Although community colleges advance equity by providing opportunities for marginalized students to pursue higher education, barriers to earning credentials remain, particularly for students of color. Higher education stakeholders are investing in “equity work” as organizations take responsibility for ensuring equitable outcomes.

From Probation to Partnership: Building Equitable Systems of Support in Community Colleges
New Directions for Community Colleges, EarlyView.ABSTRACT Community colleges serve as critical gateways to higher education for diverse student populations, yet traditional academic probation systems often exacerbate inequities by penalizing students facing systemic and personal challenges. This practitioner–scholar case study examines Clark State College's Academic Engagement Program (AEP), an ...

On the Characteristic Polynomial of the Generalized k-Distance Tribonacci Sequences
Mathematics, 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.

Racial Equity in State Funding for Community Colleges
New Directions for Community Colleges, EarlyView.ABSTRACT States vary significantly in both the amount of funding they allocate to community colleges and the mechanisms they use to distribute these funds (Kelchen et al., 2024; Mullin et al., 2015; State Higher Education Executive Officers, 2025). One major source of variation in state's approaches to funding community colleges is whether and how they

Beyond the Classroom at Dallas College: Documenting a Framework for Student Parents’ College Success
New Directions for Community Colleges, EarlyView.ABSTRACT Student parents make up a substantial share of community college enrollment, yet the support that exists is often dispersed across offices. In this article, we review and summarize research on the importance of student services for community college student parents.

Two‐Coordinate 13‐Electron PdI Complexes Stabilized by the Bulky DIMeIHeptCl NHC Ligand
Chemistry – A European Journal, EarlyView.Bulky N‐heterocyclic carbene (NHC) ligand DiMeIHeptCl stabilizes rare two‐coordinate 13‐electron PdI species. These monomeric complexes are directly observed crystallographically and by electron paramagnetic resonance (EPR) spectroscopy, and display unusual structures and radical‐type reactivity, forming Pd0(NHC) via Pd─X bond homolysis or ...

Bipartite Graphs Associated with Pell, Mersenne and Perrin Numbers
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019 In this paper, we consider the relationships between the numbers of perfect matchings (1-factors) of bipartite graphs and Pell, Mersenne and Perrin Numbers.

On some new results for the generalised Lucas sequences
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 In this paper we introduce the functions which count the number of generalized Lucas and Pell-Lucas sequence terms not exceeding a given value x and, under certain conditions, we derive exact formulae (Theorems 3 and 4) and establish asymptotic limits ...
