How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
Full-text available
An approach to artist’s multiple as noisy data from the object-phenomenon to be referred to as the work of art. Investigation of a pinus nigra needle burning. Online installation and full report available on "Research Catalogue" (link in the paper).
Chapter
Full-text available
A screen of words covers the world. Upon it, habitual patterns of perception and meaning, patterns which have been established precisely through words are projected. The glacier is the perfect, unstable system to account for how the screen begins to crack, like a sheet of ice that is no longer transparent, as language is commonly supposed to be, bu...
Article
Full-text available
Interview about visual poetry and asemic writing framed within the context of physics and conceptual art.
Book
Full-text available
On dit souvent que les conditions pour la genèse des mots vivants et l’évolution de l’écriture sont à considérer en tant qu’une partie de l’évolution de l’univers. L’établissement d’un code a posé le problème du développement de la vie et de l’écriture. Le code asémique a un sens biophysique et moléculaire. La structure primaire d’un mot est codée...
Article
Full-text available
From conceptual art to asemic writing: the methodological approach of proceeding by definition.
Preprint
Full-text available
Asemic writing points to a gradual weakening of the correlation between sign and meaning or, in the language of architecture and biology, to the confutation of the form follows function principle. Several lines of research are suitable for dealing with the intrinsic nonlinearity that follows. Topology-based methods could support or replace traditi...

Foreword in the book by Cecil Touchon about asemic writing.
Preprint
The following papers are a collection of selected theoretical works in progress and interviews about asemic writing, vispo and concrete poetry, some of which have already appeared on journals, reviews and dedicated websites.
Article
Full-text available
First appeared on «Utsanga», n.15, Francesco Aprile curator, 2018.
Article
Full-text available
This paper explores Russell's use of the sonnet as a sort of poetry gauge, a form whose structures are closer to inner discipline than to bare Literary tradition. Sonnets tend to the same subtle shape more closely than their division into different parts and rules may suggest at first. They all incarnate poetry and life at once, better than interpr...
Chapter
The initial steps to be performed in image processing are noise reduction, shading correction, contrast, and edge enhancement. Depending on the noise sources and the hardware devices involved, images can be processed via software or hardware. Quantitative image analysis deals with both collecting information from fluorescence intensity signals and...
Chapter
In modern times, there is an increasing demand for three-dimensional (3-D) optical microscopy. The main reason lies in the fact that optical microscopy is still unique in its ability to allow the complete three-dimensional examination of biological structures in a hydrated state under experimental conditions that allow the preservation of living or...
Article
Full-text available
This report deals with the fundamental quantum physics behind two-photon excitation also providing a link to the experimental consequences exploited in microscopy. The optical sectioning effect is demonstrated as well as the distribution of excitation and of fluorescence emission.
Article
In this paper, we report, for the first time, experimental evidence of multiphoton photolysis of a caged proton compound, 2-nitrobenzaldehyde (o-NBA), using a new sensor system that utilizes fluorescent-labeled nanocapsules, i.e., a fluorescent nanostructured shell of micrometric size and nanometric thickness. The photolabile compound undergoes one...
Article
Full-text available
The effects of the refractive-index mismatch in confocal laser scanning microscopy were extensively studied. The axial aberration induced in the case of fluorescent microspheres was measured. The data were used to take into account the mismatch-induced aberrations and to consider object-size influence. Then we focused on the effect of refractive-in...
Article
Full-text available
We have combined a confocal laser scanning head modified for TPE (two-photon excitation) microscopy with some spectroscopic modules to study single molecules and molecular aggregates. The behavior of the TPE microscope unit has been characterized by means of point spread function measurements and of the demonstration of its micropatterning abilitie...
Article
We have set-up a two-photon excitation fluorescence microscope based on a compact commercial confocal laser scanning head and a mode-locked Ti:Sapphire infrared pulsed laser, directly coupled in air to the scanning head We report about the architecture and the imaging capabilities of this microscope using high numerical aperture objectives, in term...
