Group analysis and similarity solutions of the compressible boundary layer equations
1989
In this paper the application of Lie's methods to the equations of the laminar boundary layer is discussed. The momentum and energy equations in Prandtl's form are considered for a steady, viscous, compressible laminar flow with non zero pressure gradient, variable viscosity and thermal conductivity. Group analysis yields similarity solutions for given pressure distributions and particular values of the invariance group parameters (group classification). Crocco's transformation is obtained for the infinite-dimensional group of the Lie's algebra admitted by the equations.
Measurement of the azimuthal ordering of charged hadrons with the ATLAS detector
2012
This paper presents a study of the possible ordering of charged hadrons in the azimuthal angle relative to the beam axis in high-energy proton-proton collisions at the Large Hadron Collider (LHC). A spectral analysis of correlations between longitudinal and transverse components of the momentum of the charged hadrons, driven by the search for phenomena related to the structure of the QCD field, is performed. Data were recorded with the ATLAS detector at center-of-mass energies of √s=900 GeV and √s=7 TeV. The correlations measured in a kinematic region dominated by low-pT particles are not well described by conventional models of hadron production. The measured spectra show features consis…
The time course of processing handwritten words: An ERP investigation
2021
Available online 25 June 2021. Behavioral studies have shown that the legibility of handwritten script hinders visual word recognition. Furthermore, when compared with printed words, lexical effects (e.g., word-frequency effect) are magnified for less intelligible (difficult) handwriting (Barnhart and Goldinger, 2010; Perea et al., 2016). This boost has been interpreted in terms of greater influence of top-down mechanisms during visual word recognition. In the present experiment, we registered the participants’ ERPs to uncover top-down processing effects on early perceptual encoding. Participants’ behavioral and EEG responses were recorded to high- and low-frequency words that varied in scr…
Amore e politica. Una nota su Arendt e Negri
2022
The return of love as a political resource is a phenomenon of modest relevance. In some cases, however, it appears as an instrument and as a theme of possible strategies of response to the changes and crises that marked the twentieth century. In this contribution we focus on the contrasting uses of political love in the very different reflections of Hanna Arendt and Antonio Negri, and in particular on the function that the reference to the past plays in them
The Freedom to Be Free. Riflessioni su uno scritto di Hannah Arendt recentemente edito per la prima volta
2018
Un saggio di Hannah Arendt è rimasto inedito per oltre 50 anni. Su quelle carte non è apposto un vero titolo, ma solo: A lecture. Il testo sviluppa uno dei temi più cari all’autrice: le diverse declinazioni della libertà e il loro rapporto con la rivoluzione. Manca di data, ma, essendo presenti molti riferimenti all’attualità, è facile dedurre che esso sia stato scritto tra la fine del 1966 e il 1967. Si tratta di un saggio apparentemente poco originale, poiché riprende molte idee espresse altrove, soprattutto nel grande trattato Sulla Rivoluzione pubblicato nel 1963. Tuttavia è interessante vedere come alcuni concetti già apparsi in altre pubblicazioni vengano impiegati per leggere gli acc…
Measurement of hard double-parton interactions inW(???) + 2-jet events at $\sqrt{s}\,=7$ TeV with the ATLAS detector
2013
The production of W bosons in association with two jets in proton–proton collisions at a centre-of-mass energy of √s=7 TeV has been analysed for the presence of double-parton interactions using data corresponding to an integrated luminosity of 36 pb[superscript −1], collected with the ATLAS detector at the Large Hadron Collider. The fraction of events arising from double-parton interactions, f[superscript (D) over subscript DP], has been measured through the p[subscript T] balance between the two jets and amounts to f[superscript (D) over subscript DP] = 0.08 ± 0.01 (stat.) ± 0.02 (sys.) for jets with transverse momentum p[subscript T] > 20 GeV and rapidity |y| < 2.8. This corresponds to a …
Hannah Arendtin poliittisen ajattelun modernit ja postmodernit piirteet : tutkielma Hannah Arendtin ajattelun filosofisesta ihmiskuvasta
2015
Tämä tutkielma tarkastelee Hannah Arendtin poliittisen ajattelun moderneja ja postmoderneja piirteitä. Tutkielma kartoittaa Arendtin ajattelun keskeisimmät teoreettiset taustavaikutteet ja motiivit, sekä esittelee Arendtin poliittisen filosofian keskeisimmät teoreettiset elementit. Keskeinen argumenttini on, että nämä elementit muodostavat yhden yhtenäisen teoreettisen projektin ja filosofisen ihmiskuvan, joka on koko Arendtin ajattelun keskeisin punainen lanka. Tutkin ja analysoin Arendtin ajattelun taustavaikutteita ja filosofista ihmiskuvaa moderni–postmoderni -keskustelun tarjoaman teoreettisen kehikon kautta. Tämä teoreettinen konteksti mahdollistaa myös Arendtia käsittelevän tutkimusk…
Modernity in Antiquity : Hellenistic and Roman Philosophy in Heidegger and Arendt
2020
This article looks at the role of Hellenistic thought in the historical narratives of Martin Heidegger and Hannah Arendt. To a certain extent, both see—with G. W. F. Hegel, J. G. Droysen, and Eduard Zeller—Hellenistic and Roman philosophy as a “modernity in antiquity,” but with important differences. Heidegger is generally dismissive of Hellenistic thought and comes to see it as a decisive historical turning point at which a protomodern element of subjective willing and domination is injected into the classical heritage of Plato and Aristotle. Arendt, likewise, credits Stoic philosophy with the discovery of the will as an active faculty constituting a realm of subjective freedom and autonom…
