A Non-Invasive and Sustainable Characterization of Pigments in Wall Paintings: A Library of Apulian Colors

Giovanna Fioretti, Marina Clausi, Giacomo Eramo, Elisabetta Longo et autres

This paper proposed a multianalytical, non-invasive, accessible and expensive (compared to traditional ones) approach for the characterization of pictorial surfaces. A set of 18 pigments and 37 mixtures widely used in the Middle Ages in the Apulia (Italy) artistic and archaeological contexts …

Identifying Dynamic Patterns of Polypharmacy for Patients with Dementia from Primary Care Electronic Health Records: A Machine Learning Driven Longitudinal Study.

Elisabetta Longo, Bruce Burnett, Sarah Bauermeister, Shang‐Ming Zhou

It is unclear how medication use evolved before diagnosis of dementia (DoD). This study aims to identify varied patterns of polypharmacy before DoD, their prevalence and possible complications. We collected primary care e-health records for 33,451 dementia patients in Wales from 1990 …

Umbral interpolation

Francesco Aldo Costabile, Elisabetta Longo

A general linear interpolation problem is posed and solved. This problem is called umbral interpolation problem because its solution can be expressed by a basis of Sheffer polynomials. The truncation error and its bounds are considered. Some examples are discussed, in particular …

An algebraic exposition of umbral calculus with application to general linear interpolation problem: A survey

Francesco Aldo Costabile, Elisabetta Longo

A systematic exposition of Sheffer polynomial sequences via determinantal form is given. A general linear interpolation problem related to Sheffer sequences is considered. It generalizes many known cases of linear interpolation. Numerical examples and conclusions close the paper.

An algebraic approach to Sheffer polynomial sequences

Francesco Aldo Costabile, Elisabetta Longo

A matrix approach to Sheffer polynomial sequences is proposed; in particular, two different determinantal forms of Sheffer sequences are given, the one as the function of a polynomial sequence of binomial type and the other as the function of the canonical base …
