An Implicit Nodal–Staggered Finite Difference Scheme for Damped Shear Beam Models Without Rotational Inertia

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop and analyze a fully discrete finite difference approximation for a damped shear beam model with mixed boundary conditions and no rotational inertia. The absence of a second‐order time derivative in the rotational equation gives rise to an asymmetric temporal structure.

A note on degenerate poly-Genocchi numbers and polynomials

Advances in Difference Equations, 2020
Recently, some mathematicians have been studying a lot of degenerate versions of special polynomials and numbers in some arithmetic and combinatorial aspects. Our research is also interested in this field.

Polynomial‐shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
A shaped electrode design for lithium niobate adaptive X‐ray mirrors connects actuator degrees of freedom to specific polynomial orders, enabling general shape control and the correction of defocus, coma and fourth‐order aberrations with a limited number of inputs.For adaptive mirrors on X‐ray beamlines and optical systems, we describe a strategy for ...

New families of special numbers and polynomials arising from applications of p-adic q-integrals

Advances in Difference Equations, 2017
In this manuscript, generating functions are constructed for the new special families of polynomials and numbers using the p-adic q-integral technique. Partial derivative equations, functional equations and other properties of these generating functions ...

Degenerate poly-Bernoulli polynomials arising from degenerate polylogarithm

Advances in Difference Equations, 2020
Recently, degenerate polylogarithm functions were introduced by Kim and Kim. In this paper, we introduce degenerate poly-Bernoulli polynomials by means of the degenerate polylogarithm functions and investigate some their properties.

Weathering the storm: Most maternal and environmental drivers of individual reproductive success do not scale up to population recruitment in a large herbivore

Journal of Animal Ecology, EarlyView.
Using 18 years of data on eastern grey kangaroos, we show that drivers of individual reproductive success often do not scale up to population recruitment. Birth asynchrony could buffer population recruitment against environmental variability, such that variables affecting individual reproduction have little impact at the population level.

Bernoulli Polynomials in Several Variables and Summation of Monomials over Lattice Points of a Rational Parallelotope

Известия Иркутского государственного университета: Серия "Математика", 2016
The Bernoulli polynomials for natural x were first considered by J.Berno\-ulli (1713) in connection with the problem of summation of the powers of consecutive positive integers. For arbitrary $x$ these polynomials were studied by L.Euler.

Trajectories of medication for opioid use disorder and their impact on HIV testing among people who inject drugs in India: A longitudinal assessment of clinic‐based data

Addiction, Volume 120, Issue 4, Page 745-755, April 2025.
Abstract Aims The aim of this study was to identify longitudinal trajectories of medication for opioid use disorder (MOUD) use throughout 1 year following MOUD initiation and to examine the association of trajectory membership with HIV testing among people who inject drugs in India.

On the 𝑞-Bernoulli Numbers and Polynomials with Weight 𝜶

Abstract and Applied Analysis, 2011
We present a systemic study of some families of higher-order 𝑞-Bernoulli numbers and polynomials with weight 𝛼. From these studies, we derive some interesting identities on the 𝑞-Bernoulli numbers and polynomials with weight 𝛼.

Cannabis use disorder in patients prescribed medical cannabis—Should we consider prescription cannabis use disorder as a new diagnostic condition?

Addiction, EarlyView.
Abstract Background and Aims The introduction of prescribed medical cannabis in many parts of the world raises issues regarding how we conceptualise Cannabis Use Disorders (CUD). The Diagnostic Statistical Manual Version 5 (DSM5) provides a framework for ‘Prescription Cannabis Use Disorder’ (Pr‐CUD) when a person is using medical cannabis only‐as ...
