Dal trascrittoma all’interattoma di miRNA: identificazione sperimentale e bioinformatica delle interazioni funzionali miRNA:mRNA
2013
I miRNA, piccole molecole endogene di RNA non codificante, regolano l’espressione genica attraverso la degradazione dei messaggeri (mRNA) o l’inibizione della traduzione. I miRNA maturi interagiscono con le proteine del complesso RISC (RNA-induced silencing complex) tra cui le proteine Argonaute (Ago), capaci di legare direttamente i miRNA e di mediare la regolazione dell’espressione genica in seguito alla interazione del miRNA con il proprio mRNA target. Un singolo miRNA può legare diversi mRNA e ciascun mRNA può essere regolato da diversi miRNA. La maggior parte dei software di predizione oggi disponibili individuano i putativi target di singoli miRNA ignorando caratteristiche di tipo glo…
Dense Geometry of Music and Visual Arts: Vanishing Points, Continuous Tonnetz, and Theremin Performance
2018
The dualism between continuous and discrete is relevant in music theory as well as in performance practice of musical instruments. Geometry has been used since longtime to represent relationships between notes and chords in tonal system. Moreover, in the field of mathematics itself, it has been shown that the continuity of real numbers can arise from geometrical observations and reasoning. Here, we consider a geometrical approach to generalize representations used in music theory introducing continuous pitch. Such a theoretical framework can be applied to instrument playing where continuous pitch can be naturally performed. Geometry and visual representations of concepts of music theory and…
Vita, morte e miracoli di Alan Mathison Turing
2007
La vita di Turing si puo leggere in molte biografie: ottima ed enciclopedica quella di Andrew Hodges (pubblicata in Italia da Bollati Boringhieri); molto piacevole l’agile libretto di Gianni Rigamonti, Turing, il genio e lo scandalo (Flaccovio editore, Palermo, 1991). In entrambi i libri si possono anche trovare cenni alla sua tragica fine, della quale la societa inglese di quel tempo non puo certo menar vanto; ma chissa come si sarebbero comportate altre societa.

Disposizioni di agenti in spazi geometrici arbitrari: un approccio basato sulla computazione evolutiva
2015
In many different social contexts, communication allows a collective intelligence to emerge. However, a correct way of exchanging information usually requires determined topological conigurations of the agents involved in the process. Such a coniguration should take into account several parameters, e.g. agents positioning, their proximity, time eficiency of communication. Our aim is to present an algorithm, based on evolutionary programming, which optimizes agents placement on arbitrarily shaped areas. In order to show its ability to deal with arbitrary bi-dimensional topologies, this algorithm has been tested on a set of differently shaped areas that present concavities, convexities and ob…

Symmetry operators in computer vision
1996
Symmetry plays a remarkable role in perception problems. For example, peaks of brain activity are measured in correspondence with visual patterns showing symmetry. Relevance of symmetry in vision was already noted by Köler in 1929. Here, properties of a symmetry operator are reported and a new algorithm to measure local symmetries is proposed. Its performance is tested on segmentation of complex visual patterns and the classification of sparse images. Copyright © 1996 Elsevier Science Ltd.
