Voigt Transform and Umbral Image

Mathematical and Computational Applications, 2020
In this paper, we show that the use of methods of an operational nature, such as umbral calculus, allows achieving a double target: on one side, the study of the Voigt function, which plays a pivotal role in spectroscopic studies and in other ...

Intertwined precariousness and precarity: Disentangling a phenomenon that characterises Spanish youth

International Journal of Social Welfare, Volume 34, Issue 1, January 2025.
Abstract The growth of non‐standard employment has emerged as a crucial factor that contributes to delays and difficulties in young people's transitions to adulthood. Previous studies have demonstrated the importance of multidimensional measures of precariousness.

Differential coping capacities underlie the overall resistance of temperate seagrasses to herbivory

Ecosphere, Volume 15, Issue 12, December 2024.
Abstract Grazing can impart long‐lasting changes in vegetated ecosystems. How ecosystems respond to herbivory depends on the ecological and evolutionary histories of their foundational species. The overall ecosystem functioning and associated biodiversity depend on these responses but there is still little understanding on how the intensity and ...

Hermite Calculus [PDF]

, 2017
We develop a new method of umbral nature to treat blocks of Her mite and of Hermite like poly- nomials as independent algebraic quantities. The Calculus we propose allows the formulation of a number of ”practical rules” allowing significant ...

The effect of group size on sleep in a neotropical bat, Artibeus jamaicensis

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 10, Page 1097-1110, December 2024.
Research Highlights We combine behavioral and physiological data to show that Jamaican fruit bats (Artibeus jamaicensis) sleeping in groups may sleep longer than individuals sleeping alone, and that behavior can be used to measure some sleep metrics in wild bats.

Evaluating use of two‐step International Ovarian Tumor Analysis strategy to classify adnexal masses identified in pregnancy: pilot study

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 6, Page 808-817, December 2024.
ABSTRACT Objectives The primary aim was to validate the International Ovarian Tumor Analysis (IOTA) benign simple descriptors (BDs) followed by the Assessment of Different NEoplasias in the adneXa (ADNEX) model, if BDs cannot be applied, in a two‐step strategy to classify adnexal masses identified during pregnancy. The secondary aim was to describe the

Intermanufacturer assessment of diagnostic performance of angiogenic ratio vs glycosylated fibronectin in women with suspected pre‐eclampsia

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 5, Page 620-625, November 2024.
ABSTRACT Objective To compare the diagnostic performance of different manufacturers' immunoassays for the soluble fms‐like tyrosine kinase‐1 (sFlt‐1)‐to‐placental growth factor (PlGF) ratio with that of a point‐of‐care (PoC) test for glycosylated fibronectin (GlyFn) in women with suspected pre‐eclampsia (PE).

On λ-linear functionals arising from p-adic integrals on Z p $\mathbb{Z}_{p}$

Advances in Difference Equations, 2021
The aim of this paper is to determine the λ-linear functionals sending any given polynomial p ( x ) $p(x)$ with coefficients in C p $\mathbb{C}_{p}$ to the p-adic invariant integral of P ( x ) $P(x)$ on Z p $\mathbb{Z}_{p}$ and also to that of P ( x 1 + ⋯

Applications of q-Umbral Calculus to Modified Apostol Type q-Bernoulli Polynomials

, 2018
This article aims to identify the generating function of modified Apostol type q-Bernoulli polynomials. With the aid of this generating function, some properties of modified Apostol type q-Bernoulli polynomials are given.

Do sexual differences in life strategies make male lizards more susceptible to parasite infection?

Journal of Animal Ecology, Volume 93, Issue 9, Page 1338-1350, September 2024.
Sexual dimorphism in coadaptive host–parasite relationships are poorly understand. The comparative nature of the presented studied as well as the generalisation of the results for the geographic region sampled makes this study of general interest of ecologists, evolutionary biologists, physiologist and parasitologist, among others.
