The entropy of alpha-continued fractions: numerical results

We consider the one-parameter family of interval maps arising from generalized continued fraction expansions known as alpha-continued fractions. For such maps, we perform a numerical study of the behaviour of metric entropy as a function of the parameter. The behaviour of entropy is known to be quite regular for parameters for which a matching condition on the orbits of the endpoints holds. We give a detailed description of the set M where this condition is met: it consists of a countable union of open intervals, corresponding to different combinatorial data, which appear to be arranged in a hierarchical structure. Our experimental data suggest that the complement of M is a proper subset of the set of bounded-type numbers, hence it has measure zero. Furthermore, we give evidence that the entropy on matching intervals is smooth; on the other hand, we can construct points outside of M on which it is not even locally monotone.Comment: 33 pages, 14 figure

Bonding of the Inner Tracker Silicon Microstrip Modules

Microbonding of the CMS Tracker Inner Barrel (TIB) and Tracker Inner Disks (TID) modules was shared among six different Italian Institutes. The organization devised and the infrastructure deployed to handle this task is illustrated. Microbonding specifications and procedures for the different types of TIB and TID modules are given. The tooling specially designed and developed for these types of modules is described. Experience of production is presented. Attained production rates are given. An analysis of the microbonding quality achieved is presented, based on bond strengths measured in sample bond pull tests as well as on rates of bonding failures. Italian Bonding Centers routinely performed well above minimum specifications and a very low global introduced failure rate, at the strip level, of only $\sim$0.015 \% is observed

I problemi di matematica della Scuola Normale Superiore di Pisa

Nasce come aggiornamento del volume precedente ("I problemi di Matematica della Scuola Normale", 1984) e raccoglie gli esercizi di matematica assegnati all'esame di ammissione alla Scuola Normale Superiore di Pisa dal 1985 al 1997, con la loro risoluzione. Per rendere più efficace lo scopo didattico viene anche presentata una scelta di problemi relativi al periodo precedente (1905-1984). Il libro si rivolge a studenti e docenti della Scuola Secondaria, e si chiude con un Glossario in cui vengono richiamati i termini usati

Administrative reform under mutating populism in office

This paper tracks the dynamics of administrative reform across two areas (civil service, simplification) in Italy, focusing on the XVIII parliamentary term, which has been characterized by the presence of populist parties in three different coalition governments (Conte I, Conte II, Draghi). The alternation in power between different governments has occurred in a context marked by the shift of the EU economic governance from a logic of conditionality to a logic of solidarity in the wake of the Covid-19 pandemic. After a decade of EU-led austerity, the shift of the EU economic governance was expected to support and enable administrative reform at the national level. Our findings reveal that the structural lack of time induced the Draghi government to focus administrative reforms on a limited number of domains to produce quick and relevant results. This selective approach focused on capacity building represented an improvement into patterns of administrative reform if compared with what happened under the Conte I and II government, which have displayed a marked chasm between the level of talk and the level of action. This has been due partly to populist parties having not pursued a distinctive agenda in matters of administrative reform beyond the loud tones, and partly to EU fiscal constraints

The Draghi Government put to the Test by the National Recovery and Resilience Plan

The political and institutional trajectory of Italy was clearly punctu- ated by the economic upheavals of the pandemic. The articles in the special issue aim to assess the character of the institutional change prompted by the economic response to the pandemic, and in particular by the National Recovery and Resilience Plan (NRRP), in different policy areas. Three contributions analyse the reform dynamics related to the strategic axis of the Italian NRRP, namely digitalization and innovation (Ottone and Barbieri), the ecological transition (Cotta and Domorenok), and social inclusion as concerns labour-market policies (Tassinari). Two contributions focus on two overarching priorities of the NRRP: gender equality (Donà) and development of southern Italy (Cerruto, Cersosimo and Raniolo). Finally, one contribution focuses on reform of the public adminis- tration, which has been identified as a key area, affecting horizon- tally all missions in the NRRP (Di Mascio, Natalini and Profeti). Overall, the articles in the special issue highlight that the pandemic has been followed by a process of institutional change that occurred both incrementally and unevenly, often disguising sub- stantial continuity
