Regularization of perturbed state-dependent sweeping processes with nonregular sets
2018
International audience; In this paper, we prove the convergence strongly pointwisely (up to a subsequence) of Moreau-Yosida regularization of perturbed state-dependent sweeping process with nonregular (subsmooth and positively alpha-far) sets in separable Hilbert spaces. Some relevant consequences are indicated.
The Narcissistic Personality Inventory 8: Validation of a Brief Measure of Narcissistic Personality
2020
The present study was conducted with the aim of constructing and validating a short form of the Narcissistic Personality Inventory (NPI). The NPI is the most widely-applied measure for the assessment of narcissistic personality traits and, therefore, it is of great relevance for many research questions in personality and social psychology. To develop the short scale, we first found the optimal eight-item solution among all valid combinations of the NPI-15 items in an exploratory subsample (n = 1,165) of our complete representative sample of the German general population. We then validated this model in a confirmatory subsample (n = 1,126). Additionally, we examined its invariance across age…
Sorveglianza sanitaria su un gruppo di lavoratori esposti a vibrazioni mano-braccio
2007
Nei lavoratori esposti a rischio da vibrazioni mano-braccio è indispensabile un’efficace sorveglianza sanitaria in linea con la recente normativa in materia, a garanzia della salute e della sicurezza nei luoghi di lavoro. In particolare abbiamo esaminato un gruppo di soggetti addetti alla manutenzione di aree verdi applicando le linee guida più recenti e la vigente normativa in tema di prevenzione(1,3) . As concerns those workers exposed to a risk of hand-arm vibration, an efficacious sanitary monitoring is necessary, according to recent norms, in order to assure health and secu - rity in workplaces. We have examined a group of people assigned to the maintenance of green spaces, applying th…
A new capability index for dynamic process analysis
2013
Nowadays, the trend to produce with reduced specification limits width and at a low defectives rate seems to be irreversible. In such conditions, reliable evaluation of the process capability level represents a crucial activity to assess the quality related performance of a production process. By adopting the classical approach, such evaluation is performed by verifying the process in-control condition and by evaluating suitable capability indices. However, considering the natural dynamic behavior of production processes, i.e. the process variability over the time domain, the in-control condition characterizes only a part of the production process functioning cycle, the one with the lowest …
Prostituzione. Aporie e tabù di un nuovo diritto penale tutorio
2018
Molteplici sono le forme attraverso le quali la prostituzione può essere esercitata e plurimi sono i suoi modelli normativi di regolamentazione: tradizionalmente, si contendono il campo il proibizionismo, il regolamentarismo e l’abolizionismo; più di recente la c.d. decriminalizzazione e il c.d. neo-proibizionismo. In questo volume, dopo una breve disamina delle possibili forme e dei plurimi significati della prostituzione, ci si sofferma preliminarmente su alcuni ordinamenti-tipo che presentano caratteristiche peculiari ora dell’uno ora dell’altro dei modelli normativi attuabili, tenendo conto anche di recenti e significative sentenze di talune Corti supreme in ordinamenti di tipo abolizio…
Syntaxin13 expression is regulated by mammalian target of rapamycin (mTOR) in injured neurons to promote axon regeneration.
2014
Injured peripheral neurons successfully activate intrinsic signaling pathways to enable axon regeneration. We have previously shown that dorsal root ganglia (DRG) neurons activate the mammalian target of rapamycin (mTOR) pathway following injury and that this activity enhances their axon growth capacity. mTOR plays a critical role in protein synthesis, but the mTOR-dependent proteins enhancing the regenerative capacity of DRG neurons remain unknown. To identify proteins whose expression is regulated by injury in an mTOR-dependent manner, we analyzed the protein composition of DRGs from mice in which we genetically activated mTOR and from mice with or without a prior nerve injury. Quantitati…
Generically split projective homogeneous varieties. II
2012
AbstractThis article gives a complete classification of generically split projective homogeneous varieties. This project was begun in our previous article [PS10], but here we remove all restrictions on the characteristic of the base field, give a new uniform proof that works in all cases and in particular includes the case PGO2n+ which was missing in [PS10].
Harnack and Shmul'yan pre-order relations for Hilbert space contractions
2015
We study the behavior of some classes of Hilbert space contractions with respect to Harnack and Shmul'yan pre-orders and the corresponding equivalence relations. We give some conditions under which the Harnack equivalence of two given contractions is equivalent to their Shmul'yan equivalence and to the existence of an arc joining the two contractions in the class of operator-valued contractive analytic functions on the unit disc. We apply some of these results to quasi-isometries and quasi-normal contractions, as well as to partial isometries for which we show that their Harnack and Shmul'yan parts coincide. We also discuss an extension, recently considered by S.~ter~Horst [\emph{J. Operato…
Integration on Surfaces
2012
We intend to study the integration of a differential k-form over a regular k-surface of class C 1 in \(\mathbb{R}^n\). To begin with, in Sect. 7.1, we undertake the integration over a portion of the surface that is contained in a coordinate neighborhood. Where possible, we will express the obtained results in terms of integration of vector fields. For example, we study the integral of a vector field on a portion of a regular surface in \(\mathbb{R}^3\) and also the integral over a portion of a hypersurface in \(\mathbb{R}^n\). In Sect. 7.3 we study the integration of differential k-forms on regular k-surfaces admitting a finite atlas.We discuss the need for the surface to be orientable so t…
