A note on normal ordering of degenerate integral powers of number operator [PDF]

Notes on Number Theory and Discrete Mathematics
This study derives the normal ordering expansion of degenerate integral powers of the number operator, (a†a)_{n,λ}, using recurrence relations for the coefficients and an operator action on number states. Here a† and a are respectively the boson creation

Asymptotic Estimates for r-Whitney Numbers of the Second Kind

Journal of Applied Mathematics, 2014
The r-Whitney numbers of the second kind are a generalization of all the Stirling-type numbers of the second kind which are in line with the unified generalization of Hsu and Shuie.

Living Through a Changing Climate: Stress, Trauma, and Gendered Resilience Among Women in Coastal and Northern Ghana

Sustainable Development, EarlyView.
ABSTRACT Climate change is reshaping everyday life in Ghana through coastal erosion, flooding, erratic rainfall, water scarcity, extreme heat, and agricultural insecurity. This study examines how these changes produce stress, trauma, and gendered resilience among women in Salakope and Choggu Yapalsi, two climate‐vulnerable communities in coastal and ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Contemporary and Future Challenges for Structured Democratic Dialogue

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Structured Democratic Dialogue (SDD) is a participatory problem structuring methodology grounded in Structured Dialogic Design Science. It was created to help diverse stakeholders co‐construct influence maps that reveal leverage points and support coordinated action.

A note on q-analogue of Hermite-poly-Bernoulli numbers and polynomials [PDF]

Mathematica Moravica, 2019
In this paper, we introduce the Hermite-based poly-Bernoulli numbers and polynomials with q-parameter and give some of their basic properties including not only addition property, but also derivative properties and integral representations.

The Hankel Transform of q-Noncentral Bell Numbers

International Journal of Mathematics and Mathematical Sciences, 2015
We define two forms of q-analogue of noncentral Stirling numbers of the second kind and obtain some properties parallel to those of noncentral Stirling numbers.

A Parametric Kind of Fubini Polynomials of a Complex Variable

Mathematics, 2020
In this paper, we propose a parametric kind of Fubini polynomials by defining the two specific generating functions. We also investigate some analytical properties (for example, summation formulae, differential formulae and relationships with other well ...

The q-Stirling numbers of the second kind and its applications

Journal of Nonlinear Sciences and Applications, 2018
Summary: The study of \(q\)-Stirling numbers of the second kind began with \textit{L. Carlitz} [Duke Math. J. 15, 987--1000 (1948; Zbl 0032.00304)]. Following Carlitz, we derive some identities and relations related to \(q\)-Stirling numbers of the second kind which appear to be either new or else new ways of expressing older ideas more comprehensively.

“Does EMI Improve Students' English?” and Other Unanswerable Questions

TESOL Quarterly, EarlyView.
Abstract Questions about EMI often begin from an apparently straightforward premise—does EMI improve students' English? This article argues that the question itself is the source of the main analytic problem. Using EMI as an exemplar of a wider problem in applied linguistics, we show why binary claims about language gain travel poorly across contexts ...
