A black-box, general purpose quadratic self-consistent field code with and without Cholesky Decomposition of the two-electron integrals
2021
We present the implementation of a quadratically convergent self-consistent field (QCSCF) algorithm based on an adaptive trust-radius optimisation scheme for restricted open-shell Hartree���Fock (ROHF), restricted Hartree���Fock (RHF), and unrestricted Hartree���Fock (UHF) references. The algorithm can exploit Cholesky decomposition (CD) of the two-electron integrals to allow calculations on larger systems. The most important feature of the QCSCF code lies in its black-box nature ��� probably the most important quality desired by a generic user. As shown for pilot applications, it does not require one to tune the self-consistent field (SCF) parameters (damping, Pulay's DIIS, and other simil…
The embodied self, the pattern theory of self, and the predictive mind
2018
Do we have to presuppose a self to account for human self-consciousness? If so, how should we characterize the self? These questions are discussed in the context of two alternatives, i.e., the no-self position held by \(\textit {Metzinger (2003, 2009)}\) and the claim that the only self we have to presuppose is a narrative self \(\textit {(Dennett, 1992; Schechtman, 2007; Hardcastle, 2008)}\) which is primarily an abstract entity. In contrast to these theories, I argue that we have to presuppose an embodied self, although this is not a metaphysical substance, nor an entity for which stable necessary and jointly sufficient conditions can be given. Self-consciousness results from an integrati…
Media councils and self-regulation in the emerging era of news automation
2020
This report introduces the present state of affairs in news automation and discusses what ethical considerations it raises in the work of media councils. Based on a European-wide research project, the three key takeaways are as follows:1) Large media players use automatically updated counters and infographics, but the automated gener-ation of news text is still mainly experimental in nature. We need to keep our eyes open to the possible need for self-regulatory guidance on news automation, though there are as yet no urgent issues. 2) We must not underestimate the technical progress already made in the field. Issues regarding data, agency and transparency should not be overlooked when discus…
SELVICOLTURA ALPINA E SELVICOLTURA APPENNINICA: ELEMENTI DI CONTATTO E DI DIFFERENZIAZIONE
2009
Riassunto Il rapporto tra boschi e popolazioni locali sulle Alpi come sugli Appennini, seppur in momenti storici differenti, è stato caratterizzato dalla distruzione e sfruttamento intensivo, protrattisi fino alla metà del secolo scorso, cui hanno fatto seguito la ricostituzione sia mediante rimboschimenti sia con il miglioramento dei boschi esistenti. Partendo dai presupposti sui quali si è imperniata l’attività forestale che ha caratterizzato, nel corso degli ultimi cinquant’anni, l’approccio selvicolturale nei due contesti e da una puntuale e documentata analisi, nel lavoro vengono evidenziati gli elementi di differenziazione tra la selvicoltura naturalistica applicata in ambiente alpino…
Vetrinizzazione vs. Devetrinizzazione
2008
L'articolo prende posizione intorno al concetto di “Vetrinizzazione Sociale” così come è stato inteso dal sociologo Vanni Codeluppi. Al vaglio di un’analisi semiotica, il dispositivo delle vetrine si rivelerà molto più complesso di quanto si sia creduto. Più che dispositivo di “assimilazione all’esibizione” cui tenderebbe ogni ambito della nostra vita sociale, la vetrina è il discrimine che oppone /pubblico/e /privato/ nella città regolando e rinnovando quotidianamente il senso estetico nella vita di tutti i giorni: è guardando le vetrine che si capisce cosa è di moda e cosa no ma soprattutto è attraverso le vetrine che si può capire chi si è (come fa Andy Warhol in un suo celebre aforisma)…
Apprendre à manger. Sémiotique des objets de table pour enfants
2021
The subject of children at the table is related to that of conviviality on two levels. Firstly, at the level of the acquisition of social rules concerning the ways of being at the table, the codes of the meal, the recognition of appropriate behaviour in different contexts (at home, outside, formal, informal, etc.), in short, the "have to". Secondly, at the level of the acquisition of a general know-how, represented by all the somatic behaviours necessary for the consumption of the meal: learning to chew solid food, to drink from a glass, to use cutlery, to handle plates, bowls, soup plates, and so on. In this essay, we will analyse table objects designed for children (glasses, cutlery, plat…
Identification of a new nonsense mutation (Tyr129Stop) of the SRY gene in a newborn infant with XY sex-reversal.
2004
Point mutations and deletions of SRY gene have been described in several cases of XY gonadal dysgenesis. To date, most of these mutations affect the HMG domain of SRY which plays a central role in DNA binding activity of SRY. We report on a non-mosaic XY sex-reversed newborn girl (completely female external genitalia). The direct sequencing of SRY showed a new nonsense mutation in a codon of SRY gene flanking the 3' end of the HMG domain: a thymine is replaced by a guanine at position +387 in codon 129, resulting in the replacement of the amino acid tyrosine (TAT) by a stop codon (TAG). The new mutation of this patient provides further evidence to support the functional importance of the pu…
L’intervento delle sezioni Unite nel dibattito sul reato di accesso abusivo ad un sistema informatico di cui all’art. 615 ter c.p.
2012
Con sentenza depositata il 7 febbraio 2012 le Sezioni Unite si sono pronunciate sul dibattito che riguarda la configurabilità del reato previsto ex art. 615 ter c.p. nel caso in un cui un soggetto legittimamente autorizzato ad accedere al sistema informatico o telematico vi operi per il conseguimento di finalità illecite. Da lungo tempo su questo tema si sono sviluppati due opposti orientamenti giurisprudenziali. Il primo giunge ad ammettere l’illecito sulla base dell’analogia con la fattispecie di violazione di domicilio e la valorizzazione delle finalità sottese alla condotta del soggetto agente. Il secondo, invece, focalizza l’attenzione sul dato letterale e sul momento consumativo del d…
Limits to Arbitrage and Interest Rates: a Debate Between Keynes, Hawtrey and Hicks
2018
International audience; This paper deals with a debate between Hawtrey, Hicks and Keynes concerning the capacity of the central bank to influence the short-term and the long-term rates of interest. Both Hawtrey and Keynes considered the central bank’s ability to influence short-term rates of interest. However, they do not put the same emphasis on the study of the long-term rates of interest. According to Keynes, long-term rates are influenced by future expected short-term rates (1930, 1936), whereas for Hawtrey (1932, 1937, 1938), long-term rates are more dependent on the business cycle. Short-term rates do not have much effect on long-term rates according to Hawtrey. In 1939, Hicks enters …
Video Scene analysis for a configurable hardware accelerator dedicated to Smart Camera
2012
International audience; According to the Center for Research and Prevention of Injuries report, fall-caused injuries of elderly people in UE- 27 are five times as frequent as other injury causes which reduce considerably their mobility and independence. Among the diverse applications of computer vision systems, object detection and event recognition are of the most prominent related recognition and motion analysis, that is, researchers had the idea to spread it in fall detection. The fall event, extracted automatically from the video scene represents itself, crucial information that can be used to alert emergency. In this context, visual information on the corresponding scene is highly impo…
