Profile of microbial communities on carbonate stones of the medieval church of San Leonardo di Siponto (Italy) by Illumina-based deep sequencing

Applied Microbiology and Biotechnology, 2016
Comprehensive studies of the biodiversity of the microbial epilithic community on monuments may provide critical insights for clarifying factors involved in the colonization processes. We carried out a high-throughput investigation of the communities colonizing the medieval church of San Leonardo di Siponto (Italy) by Illumina-based deep sequencing ...

The Sequence of Leonardo's Sketches for The Virgin and Child with Saint Anne and Saint John the Baptist

The Art Bulletin, 1983
By means of a close inspection and intense analysis of Leonardo da Vinci's sketches for The Virgin and Child with Saint Anne and Saint John the Baptist on a sheet in the British Museum, this study reveals Leonardo's systematic development of the composition for his cartoon in the National Gallery, London, and sheds new light on his methods in composing.

Closed-Form Solutions of Second-Order Leonardo-Type Sequences: Homogeneous Counterparts in Jacobsthal and Mersenne Numbers

Asian Journal of Current Research
The objective of this study is to derive explicit closed-form solutions for second-order nonhomogeneous linear recurrence relations with polynomial inputs, formulated as generalized Leonardo-type sequences. A central aspect of the framework is the multiplicity parameter r, which measures the occurrence of the root 1 in the characteristic equation. This

Closed-Form Solutions of Third-Order Leonardo-Type Sequences: Third-Order Jacobsthal, Graham, and Jacobsthal-Narayana Families as Homogeneous Counterparts

Asian Basic and Applied Research Journal
This paper develops unified closed-form formulas for third-order nonhomogeneous linear recurrence relations of Leonardotype sequences, where the driving term is taken to be a polynomial. The method proceeds by decomposing each recurrence into its homogeneous and particular components, yielding explicit solutions that depend simultaneously on the ...
