On a class of polynomials connected to Bell polynomials

, 2018
In this paper, we study a class of sequences of polynomials linked to the sequence of Bell polynomials. Some sequences of this class have applications on the theory of hyperbolic differential equations and other sequences generalize Laguerre polynomials and associated Lah polynomials.

On degenerate central complete bell polynomials

Applicable Analysis and Discrete Mathematics, 2019
In this paper, we consider of generalized central complete and incomplete Bell polynomials called degenerate central complete and incomplete Bell polynomials. These polynomials are generalizations of the recently introduced central complete Bell polynomials and `degenerate' analogues for the central complete and incomplete Bell polynomials.

Hydrodynamic gradients affect facilitation in soft sediment communities

Journal of Animal Ecology, EarlyView.
This study extends ecological theory on facilitation to marine soft‐sediment systems and offers insight into the functional role of habitat‐forming infauna. Abstract Positive species interactions, or facilitation, are fundamental drivers of ecological community assembly and stability.

Bell Polynomials Approach Applied to (2 + 1)-Dimensional Variable-Coefficient Caudrey-Dodd-Gibbon-Kotera-Sawada Equation

Abstract and Applied Analysis, 2014
The bilinear form, bilinear Bäcklund transformation, and Lax pair of a (2 + 1)-dimensional variable-coefficient Caudrey-Dodd-Gibbon-Kotera-Sawada equation are derived through Bell polynomials. The integrable constraint conditions on variable coefficients

The Value of Controlling Wilding Conifers in New Zealand

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Exotic, invasive conifer tree species, known as ‘wilding conifers’, pose a significant threat to natural ecosystems and are costly to manage, creating a need to identify community preferences in order to inform and balance public investment in their control.

Polygenic prediction of cannabis‐related outcomes: Evidence from the Avon Longitudinal Study of Parents and Children longitudinal cohort and the European gene–environment interaction case–control study

Addiction, EarlyView.
Abstract Background and aims Polygenic risk scores (PRSs) for cannabis use disorder (CUD), major depressive disorder (MDD), insomnia and chronic pain, and early age at cannabis initiation might be linked to problematic cannabis use. We tested whether: (1) higher PRS for CUD, MDD, insomnia and chronic pain are associated with earlier initiation and ...

Sleep profiles in individuals with rare neurogenetic syndromes

Developmental Medicine &Child Neurology, EarlyView.
Aim To characterize sleep profiles in individuals with neurogenetic disorders (NGDs) and examine the contribution of key clinical and psychiatric symptoms to these profiles. Method The parents of 248 individuals (aged 3–45 years) diagnosed with a range of NGDs, including PTEN hamartoma tumor syndrome (n = 111), SYNGAP1‐related intellectual disability ...

Recurrence for probabilistic extension of Dowling polynomials

Open Mathematics
Spivey found a remarkable recurrence relation for Bell numbers, which was generalized to that for Bell polynomials by Gould-Quaintance. The aim of this article is to generalize their recurrence relation for Bell polynomials to that for the probabilistic ...

Cost‐effectiveness of investing in earlier access to diabetic foot services: A multi‐centre pre‐post study

Diabetic Medicine, EarlyView.
Abstract Aims We evaluated the cost‐effectiveness of implementing a novel funding model to incentivise earlier access of patients with diabetes‐related foot disease (DFD) to diabetic foot services (DFS). Methods In this multi‐centre pre‐post study, we compared the cost, quality‐adjusted life year (QALY) and clinical outcomes of patients with diabetes ...

Fourier series of functions involving higher-order ordered Bell polynomials

Open Mathematics, 2017
In 1859, Cayley introduced the ordered Bell numbers which have been used in many problems in number theory and enumerative combinatorics. The ordered Bell polynomials were defined as a natural companion to the ordered Bell numbers (also known as the ...
