Some identities of degenerate multi-poly-Changhee polynomials and numbers

open access: yesElectronic Research Archive, 2023
Recently, many researchers studied the degenerate multi-special polynomials as degenerate versions of the multi-special polynomials and obtained some identities and properties of the those polynomials.

On the maximum of Stirling numbers of the second kind

open access: yesJournal of Combinatorial Theory, Series A, 1973
AbstractA technique is illustrated for finding an estimate of the Stirling numbers of the second kind, Sn, r(1 ⩽ r ⩽ n), as n → ∞, for a certain range of values of r. It is shown how the estimation can be found to any given degree of approximation. Finally, the location of the maximum of Sn, r (1 ⩽ r ⩽ n) and the value of the maximum are computed.

Size Effect on Photothermal Heating Ability of Gold Bipyramids

open access: yesAdvanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Some identities related to degenerate r-Bell and degenerate Fubini polynomials

open access: yesApplied Mathematics in Science and Engineering, 2023
Many works have been done in recent years as to explorations for degenerate versions of some special polynomials and numbers, which began with the pioneering work of Carlitz on the degenerate Bernoulli and degenerate Euler polynomials.

Dirichlet series and series with Stirling numbers

open access: yesCubo, 2023
This paper presents a number of identities for Dirichlet series and series with Stirling numbers of the first kind. As coefficients for the Dirichlet series we use Cauchy numbers of the first and second kinds, hyperharmonic numbers, derangement numbers ...

Synthesis and Application of Bioactive N‐Functionalized Aziridines

open access: yesAngewandte Chemie, EarlyView.
This review discusses modern synthetic methods for the preparation of aziridine‐containing small molecules, including biocatalytic, electrocatalytic, and photocatalytic strategies. We highlight the compatibility of various synthetic methods with control of the exocyclic N‐substituent.

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.

Truncated Fubini Polynomials

open access: yesMathematics, 2019
In this paper, we introduce the two-variable truncated Fubini polynomials and numbers and then investigate many relations and formulas for these polynomials and numbers, including summation formulas, recurrence relations, and the derivative property.
