Study of Antibiotic Resistance Potential of Spiders Bacteriota and Comparison With the Antibacterial Effect of Essential Oils

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
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

(Discrete) Almansi Type Decompositions: An umbral calculus framework based on $\mathfrak{osp}(1|2)$ symmetries

open access: yes, 2011
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 $

Nutrients and warm temperatures explain a seasonal cycle of colonization and ecosystem collapse in a floodplain pond

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
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

open access: yes, 2011
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

open access: yesDiscrete Mathematics, 2009
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

open access: yesMathematics
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.

Bridging Regional Corporate Sustainability Differences With Diasporic Insights: A Case Made by the Indian Diaspora in Australia

open access: yesBusiness Strategy &Development, Volume 8, Issue 3, September 2025.
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

open access: yesAustralian Journal of Public Administration, Volume 84, Issue 3, Page 520-538, September 2025.
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 ...
