Massive quarks in NLO dipole factorization for DIS : Longitudinal photon

2021

In this work, we will present the first complete calculation of the one-loop longitudinal photon-to-quark-antiquark light cone wave function, with massive quarks. The quark masses are renormalized in the pole mass scheme. The result is used to calculate the next-to-leading order correction to the high energy Deep Inelastic Scattering longitudinal structure function on a dense target in the dipole factorization framework. For massless quarks the next-to-leading order correction was already known to be sizeable, and our result makes it possible to evaluate it also for massive quarks.

Reducing Local Alphabet Size in Recognizable Picture Languages

2021

A recognizable picture language is defined as the projection of a local picture language defined by a set of two-by-two tiles, i.e. by a strictly-locally-testable (SLT) language of order 2. The family of recognizable picture languages is also defined, using larger k by k tiles, \(k>2\), by the projection of the corresponding SLT language. A basic measure of the descriptive complexity of a picture language is given by the size of the SLT alphabet using two-by-two tiles, more precisely by the so-called alphabetic ratio of sizes: SLT-alphabet/picture-alphabet. We study how the alphabetic ratio changes moving from two to larger tile sizes, and we obtain the following result: any recognizable pi…

Ancora sulle "esplosive palatali" nelle inchieste dell'Atlante Linguistico del Mediterraneo (ALM): i punti albanesi

2021

Tra i «Problemi redazionali» emersi in fase di controllo e organizzazione dei materiali giunti dalla campagna di rilevamenti dell’Atlante Linguistico del Mediterraneo (ALM), Berruto (1971-1973) rileva la proliferazione e l’eterogeneità di alcune scelte grafemiche operate da diversi raccoglitori che, impegnati in una trascrizione più o meno puntuale delle risposte ottenute, avevano interpretato e risolto variamente alcune delle indicazioni previste nel sistema di trascrizione fonetica che accompagnava il Questionario. Particolarmente complesso era emerso il quadro relativo alla trascrizione di alcune consonanti del settore “palatale”, per le quali i grafemi (e i foni a essi corrispondenti) p…

Settore L-FIL-LET/12 - Linguistica ItalianaAmong the «Editorial problems» that emerged during the control and organization of the materials coming from the survey campaign of the Atlante Linguistico del Mediterraneo (ALM) Berruto (1971-1973) notes the proliferation and heterogeneity of some graphemic choices made by different field researchers. As they were engaged in a more or less punctual transcription of the answers obtained they had interpreted and solved differently some of the directions provided in the phonetic transcription system that accompanied the Questionnaire. The picture relating to the transcription of some consonants of the palatal sector had emerged as particularly complex since the graphemes (and the corresponding phones) foreseen in the original system (ALM 1959) were insufficient. Not even the 1971 updates meant to improve the representation of some phonetic features emerged from the investigations in the operations of Response reviewing allowed to obtain a clear homogeneous picture regarding the «plosive palatal» consonants. With regard to the phonetic trait under scrutiny I have already had the opportunity to propose a path aiming to the achievement of possible operational solutions. This has taken place in view of the planned simplification / homologation and transcoding phase from the ALM original system to the IPA one - while proceeding from the examination of the Schedoni’s current state with regard to the surveys referring to central-southern Italy Corsica and Sicily (see Matranga 2019). The scope is now to investigate the same phonetic trait as proven in the materials about the surveys carried out by Lirak Dodbiba in the ALM’s three Albanian points.

Il Polar prima del Polar: il poliziesco italo-americano tra fine Ottocento e gli anni Trenta del Novecento

2018

Tra la fine dell’Ottocento e gli anni Trenta del Novecento, alcuni Italiani immigrati negli Stati Uniti – quali, fra gli altri, Bernardino Ciambelli, Italo Stanco, Garibaldi Marto Lapolla, Louis Forgione, nonché il sodalizio letterario costituito da Michael Fiaschetti e Prosper Buranelli – si sono cimentati nel genere del poliziesco con alcuni testi che, partendo da alcune delle caratteristiche tipiche del Mystery, quali la serializzazione e l’incardinamento della fabula in uno specifico contesto urbano, insieme ad alcuni degli elementi caratteriali dei personaggi dell’Hard boiled non perdono mai di vista la peculiare ‘missione’ di denuncia politica, economica e sociale. Facendo del problem…

Settore L-FIL-LET/14 - Critica Letteraria E Letterature ComparateBetween late XIX and the first 30 years of the XX Century some Italians immigrated to the United States – such as Bernardino Ciambelli Italo Stanco Garibaldi Marto Lapolla Louis Forgione Michael Fiaschetti and Prosper Buranelli – wrote some texts that starting from the typical features of Mystery (serialization and incardination of the fabula in a specific urban context) together with some of the characteristic elements of the Hard boiled never lose sight of the peculiar 'mission' of political economic and social denunciation. Taking the political and social problems as the primary key of their works these writers want to remove the defamatory role attributed by the public opinion fomented by the press to Italian immigrated community. Their works don’t have the main intent to stage detectives that can solve a case or unmask a culprit but rather they aim to denounce social distortions corruption and injustices suffered by an entire community and not least to indicate the picture of what on the contrary that same society could have been.

Cinema e fotografia. Su "Palermo Shooting" di Wim Wenders

2022

The topic complex of photographer and photography is of central importance for Wim Wenders' cinematic and literary work. Of course, it is not just about photography itself, but a subtle play with narrative and metapoetic references. All the figures of photographers who from the beginning repeatedly appear as protagonists in Wenders' films also tell of pictures and how to make them. Most of them are men who have a disturbed relationship to the world around them and to their own selves. Men who travel in search of a truer grip on reality.

Line

2020

In the Elements of Geometry, Euclid defines the line as “a length without breadth,” an element without width and depth. The concept of line occurs in propositions, both theorems and proofs, given the postulates that it is possible to draw a straight line between any two points and to extend continuously any line. In Euclid’s Optics, lines are the subject of theorems. Rubin studied the perceptual conditions that could have given an intuitive contribution to the definition of geometrical objects that like in Euclid’s geometry do not occur in experience, yet have a relation with visual constructions. Pictures exploit markings endowed with perceptual linearity and continuity which realize lines…

Drawing

2020

A drawing is the result of the production of marks on a surface with suitable means to represent a scene, concrete or abstract objects for technological, scientific, artistic, communicative aims. Some theories claimed that drawing is founded on symbolic systems that are culture-dependent. Evidence has been found that the ability of recognizing what drawings represent is widespread across ages, cultures and species. Drawing may be founded on shared cognitive capacities. These capacities can be abstractly described as the graphic and the denotation system.

Picture

2020

Pictures are a presentation whose structure is decomposable into a surface, an arrangement of markings, the appearance of something in front of, before or behind the surface, the reference to a scene of the real or a possible world, whose aspects and concrete or abstract states of affairs are displayed by the appearance. Pictures are a kind of markings, namely patterns perceived on a surface, which do not yet convey information about it. Markings depend on surfaces. No marking exists without a surface, while the opposite is true. There is a variety of markings according to the technique and the tools chosen to produce them. Surfaces serve as a medium either as a support or as that which aff…
