Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...

No App, No Entry: Conceptualizing Digital Technology Captivity in Service Access
ABSTRACT We introduce Digital Technology Captivity (DTC), a form of consumer vulnerability that arises when digital technologies become the mandatory gateway to essential services. When access is tied to systems that feel unfamiliar, complex, or intimidating—and when preferred alternatives are limited—consumers may experience heightened vulnerability ...

In the paper, by virtue of the Faà di Bruno formula, some properties of the Bell polynomials of the second kind, and an inversion formula for the Stirling numbers of the first and second kinds, the authors establish meaningfully and significantly two ...

The r-central factorial numbers with even indices
In this paper, we introduce the r-central factorial numbers with even indices of the first and second kind as extended versions of the central factorial numbers with even indices of both kinds.

Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach
ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

New type of degenerate Daehee polynomials of the second kind
Recently, Kim and Kim (Russ. J. Math. Phys. 27(2):227–235, 2020) have studied new type degenerate Bernoulli numbers and polynomials by making use of degenerate logarithm. Motivated by (Kim and Kim in Russ. J. Math. Phys. 27(2):227–235, 2020), we consider

The higher-order type 2 Daehee polynomials associated with p-adic integral on ℤp
In this paper, the higher-order type 2 Daehee polynomials are introduced and some of their relations and properties are derived. Then, some p-adic integral representations of not only higher-order type 2 Daehee polynomials and numbers but also type 2 ...

ABSTRACT Using public ethnography anchored in the post‐development theory and interpretivist epistemological paradigm, this study examines what we term the ‘socio‐cultural milieus dynamics’ (SCMD) of the Solomon Islands (SI) and how these shape meaning, discourse, and practice in ways that influence Australia's aid localisation efforts and aid outcomes.

On degenerate multi-poly-derangement polynomials and numbers
The problem of counting derangements was begun in 1708 by Pierre R[Formula: see text]mond de Montmort (see [Carlitz. The number of derangements of a sequence with given specification. Fibonacci Quart. 1978;16:255–258], [Clarke and Sved.
