Some identities on derangement and degenerate derangement polynomials

open access: yes, 2017
In combinatorics, a derangement is a permutation that has no fixed points. The number of derangements of an n-element set is called the n-th derangement number.

Thermal‐Infrared Measurements of the North‐East Tower at Ardrossan Castle

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Thermal‐infrared imaging of buildings is used to investigate a range of phenomena including the accumulation of moisture. In general, the presence of moisture poses a direct danger to historic structures and must be characterized prior to any intervention.

Degenerate Hermite poly-Bernoulli numbers and polynomials with q-parameter

open access: yes, 2020
In this paper, we introduce a new class of degenerate Hermite poly-Bernoulli polynomials with q-parameter and give some identities of these polynomials related to the Stirling numbers of the second kind.

Combinatorial Entropy for Distinguishable Entities in Indistinguishable States

open access: yes, 2007
The combinatorial basis of entropy by Boltzmann can be written $H= {N}^{-1} \ln \mathbb{W}$, where $H$ is the dimensionless entropy of a system, per unit entity, $N$ is the number of entities and $\mathbb{W}$ is the number of ways in which a given ...

One‐Step Electrodeposition of Iron Oxyhydroxide Onto 3D Porous Graphene Substrates for on Chip Asymmetric Micro‐Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A micro‐supercapacitor with electrodeposited iron oxyhydroxide (FeOOH) as the negative electrode and birnessite manganese oxide (MnO2) as the positive electrode achieves a 2 V working voltage, stable cycling in an aqueous electrolyte, and high energy and power densities of 21 μWh cm‐2 and 2.5 mW cm‐2 respectively.

The Convergence of Artificial Intelligence and Sustainability Reporting: A Systematic Review of Applications, Challenges and Future Directions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This research examines the potential of artificial intelligence (AI) to improve sustainability reporting, particularly in relation to environmental, social and governance (ESG) issues. Despite growing interest in the field, the integration of AI in sustainability remains underexplored, especially in terms of its impact on data accuracy ...

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

open access: yesChemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Graph presentations for moments of noncentral Wishart distributions and their applications

open access: yes, 2010
We provide formulas for the moments of the real and complex noncentral Wishart distributions of general degrees. The obtained formulas for the real and complex cases are described in terms of the undirected and directed graphs, respectively.

Towards justice‐oriented climate change and sustainability education: Perspectives from school teachers in England

open access: yesThe Curriculum Journal, EarlyView.
Abstract Education, including school education, is widely understood as fundamental to a just response to global climate and ecological crises. We examined the practices of teachers based in England focused on climate change and sustainability education (CCSE).

Probabilistic multi-Stirling numbers of the second kind associated with random variables

open access: yesApplied Mathematics in Science and Engineering
This paper investigates a probabilistic extension of the multi-Stirling numbers of the second kind and a ‘poly' version of the probabilistic degenerate Lah-Bell polynomials.
