Antibacterial effect comparison between spiders and essential oils. ABSTRACT Insect microorganisms significantly affect the diet, well‐being and behavior of their hosts. However, the microbiota of spiders, which are important natural enemies of pests, is still largely unknown. To gain insight into the bacterial composition of spiders and their possible

We introduce the umbral calculus formalism for hypercomplex variables starting from the fact that the algebra of multivariate polynomials $\BR[\underline{x}]$ shall be described in terms of the generators of the Weyl-Heisenberg algebra. The extension of $

Abstract Resilient ecosystems maintain similar species diversity and composition despite extreme environmental variation, while ecosystem collapse can be characterized by high mortality rates and decreased species diversity. Submerged aquatic macrophytes often support species diversity by providing habitat, shelter, food, and oxygen for fish and ...

Bernoulli type polynomials on Umbral Algebra
The aim of this paper is to investigate generating functions for modification of the Milne-Thomson's polynomials, which are related to the Bernoulli polynomials and the Hermite polynomials. By applying the Umbral algebra to these generating functions, we

Identities on Bell polynomials and Sheffer sequences
The paper gives two new characterizations of Sheffer sequences in terms of exponential partial Bell polynomials. This yields connection between Sheffer sequences and Riordan arrays. Several general identities are established for Bell polynomials and Sheffer sequences, which specialize to elegant identities for associated sequences and cross sequences.

Symbolic Methods Applied to a Class of Identities Involving Appell Polynomials and Stirling Numbers
In this paper, we present two symbolic methods, in particular, the method starting from the source identity, umbra identity, for constructing identities of s-Appell polynomials related to Stirling numbers and binomial coefficients.

ABSTRACT Corporate Social Responsibility (CSR) programs are often developed in the Global North and applied in the Global South with minimal input from local Southern stakeholders. This may lead to a limited understanding of Southern cultural contexts, making CSR programs less effective.

How the political elite make decisions
Abstract The political elite make policy decisions in noisy environments and under time pressure, and so are prone to using heuristics. There are conflicting schools of thought as to whether it is appropriate for them to do so. Experienced decision‐makers are thought to be more effective at using heuristics, so it is possible that for the political ...
