Sous-facteurs de L(F∞) d'indice 4cos2π/n,n≥3
No full textLet Q be a factor of type II1, λ a number in the Jones discrete series {4cosπ/m:m≥3}, and {ei} the Jones projections associated with λ. Denote by A2n and A1n the finite-dimensional von Neumann algebras generated, respectively, by {1,e2,⋯,en} and {1,e1,⋯,en}, with the corresponding traces. The author shows that, for n sufficiently large, the index of the inclusion An=(Q⊗A2n)∗A2nA1n⊂(Q⊗A2n+1)∗A2n+1A1n+1=An+1 is equal to λ (here ∗ denotes the reduced, amalgamated free product of the algebras in question). Using the random matrix model of Voiculescu, he proves that if Q is the von Neumann algebra L(F∞) of the free group with infinitely many generators, then An is isomorphic to L(F∞).
The two facts together imply the existence, for any λ in the Jones discrete series, of an irreducible subfactor of L(F∞) of index λ. This constitutes the first example of a nonhyperfinite, non-Γ II1 factor such that its Jones invariant is fully computable (the existence of nonirreducible subfactors of L(F∞) for any index ≥4 is a simple consequence of known results)

BACKGROUND:
There is a paucity of prospective and controlled data on the comparative effectiveness of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in a real-world setting.
OBJECTIVES:
This analysis aims to describe 1-year clinical outcomes of a large series of propensity-matched patients who underwent SAVR and transfemoral TAVR.
METHODS:
The OBSERVANT (Observational Study of Effectiveness of SAVR-TAVI Procedures for Severe Aortic Stenosis Treatment) trial is an observational prospective multicenter cohort study that enrolled patients with aortic stenosis (AS) who underwent SAVR or TAVR. The propensity score method was applied to select 2 groups with similar baseline characteristics. All outcomes were adjudicated through a linkage with administrative databases. The primary endpoints of this analysis were death from any cause and major adverse cardiac and cerebrovascular events (MACCE) at 1 year.
RESULTS: The unadjusted enrolled population (N = 7,618) included 5,707 SAVR patients and 1,911 TAVR patients. The matched population had a total of 1,300 patients (650 per group). The propensity score method generated a low-intermediate risk population (mean logistic EuroSCORE 1: 10.2 ± 9.2% vs. 9.5 ± 7.1%, SAVR vs. transfemoral TAVR; p = 0.104). At 1 year, the rate of death from any cause was 13.6% in the surgical group and 13.8% in the transcatheter group (hazard ratio [HR]: 0.99; 95% confidence interval [CI]: 0.72 to 1.35; p = 0.936). Similarly, there were no significant differences in the rates of MACCE, which were 17.6% in the surgical group and 18.2% in the transcatheter group (HR: 1.03; 95% CI: 0.78 to 1.36; p = 0.831). The cumulative incidence of cerebrovascular events, and rehospitalization due to cardiac reasons and acute heart failure was similar in both groups at 1 year.
CONCLUSIONS:
The results suggest that SAVR and transfemoral TAVR have comparable mortality, MACCE, and rates of rehospitalization due to cardiac reasons at 1 year. These data need to be confirmed in longer term and dedicated ongoing randomized trial
Politica e amministrazione, tra etica, managerialità e responsabilità
No full textIl volume raccoglie le versioni, approfondite e rielaborate, delle relazioni discusse in occasione del convegno dal titolo “Politica e amministrazione. Etica, managerialità e responsabilità”, organizzato in onore di Gianfranco D’Alessio. L’oggetto di analisi, la dirigenza amministrativa, è discusso e analizzato, da un lato, in relazione ai principi costituzionali di imparzialità e di buon andamento della Pubblica Amministrazione e, dall’altro, al rapporto che questa instaura con gli organi politici. Il tema è affrontato con approcci variegati e da prospettive molteplici, secondo una impostazione che riflette la pluralità delle competenze e delle esperienze, professionali ed accademiche di ciascun autore.The volume collects the expanded and revised versions of the presentations discussed during the conference titled "Politics and Administration. Ethics, Managerialism, and Accountability," organized in honour of Gianfranco D’Alessio. The focus is on administrative leadership, discussed and analysed from two perspectives. Firstly, in relation to the constitutional principles of impartiality and good administration. Secondly, with reference to the relationship it establishes with political bodies. The topic is approached from various angles and multiple perspectives, reflecting the diversity of skills and experiences, both professional and academic, of each author
A regularization method for discrete Fourier polynomials.
No full textAbstractIn this paper we present a regularization method for discrete Fourier polynomials in one and two variables. The easy relation between the discrete Fourier coefficients and those of the regularized polynomial is proved. A good automatic choice of the regularization parameter σ is proposed and some numerical results are presented
