Subring of constants of a ring of characteristic p>0
Marilena Crupi
Le Matematiche , 1993,
Abstract: Let A be a local ring of characteristic p>0 which has a p-basis over a subring C, and B be the subring of constants of A for a derivation (or derivations ) of A over C. We give a sufficient condition for B to have a p-basis over C. We add some examples.
Beyond the Pillars of Hercules: Linked data and cultural heritage Oltre le colonne d'Ercole: Linked data e cultural heritage
Gianfranco Crupi
JLIS.it , 2013, DOI: 10.4403/jlis.it-8587
Abstract: The purpose of Linked Data is to develop a total data space (the data web) able to mutually connect and enrich shared databases. Libraries therefore have the opportunity to integrate the structured information of their catalogs with information from other multiple sources and to make them more accessible by building them on web standards. The ability model the data, making them accessible and preserving the contextualization is proposed as a criterion for determining the quality of a library. The article deals with the essential articulation of semantic web and its application in the universe of libraries, and the opportunity to use shared languages, meta-languages, controlled vocabularies and ontologies that are able to meet the need for automatic processing.
Closed orders and closed graphs

Mathematics , 2015,
Abstract: The class of closed graphs by a linear ordering on their sets of vertices is investigated. A recent characterization of such a class of graphs is analyzed by using tools from the proper interval graph theory.
Safety and Efficacy of Paliperidone Extended-Release in Acute and Maintenance Treatment of Schizophrenia
Edoardo Spina and Rosalia Crupi
Journal of Central Nervous System Disease , 2012, DOI: 10.4137/JCNSD.S1607
Abstract: Paliperidone, the major active metabolite of risperidone, is a second-generation antipsychotic that has been developed as an extended-release (ER) tablet formulation that minimizes peak-trough fluctuations in plasma concentrations, allowing once-daily administration and constant drug delivery. Paliperidone ER has demonstrated efficacy in the reduction of acute schizophrenia symptoms in 6-week, placebo-controlled, double-blind trials and clinical benefits were maintained in the longer-term according to extension studies of up to 52 weeks in duration. Compared with quetiapine, paliperidone ER was associated with a more rapid symptom improvement. In addition, it was more effective than placebo in the prevention of symptom recurrence. Paliperidone ER is generally well tolerated with a predictable adverse event profile. Like risperidone, it is associated with a dose-dependent risk of extrapyramidal symptoms and prolactin elevation. Short- and longer-term studies have indicated a low liability for paliperidone ER to cause metabolic (ie, weight gain, hyperglycaemia and lipid dysregulation) or cardiovascular adverse effects. Available safety data from elderly patients appear to be promising. Due to negligible hepatic biotransformation, paliperidone ER is unlikely to be involved in clinically significant metabolic drug-drug interactions. Additional active comparator trials evaluating efficacy, tolerability and cost-effectiveness are required to better define the role of paliperidone ER in the treatment of schizophrenia in relation to other currently available second-generation antipsychotics, particularly risperidone.
Actions of formal groups on special quotients of algebras
Crupi, M,Restuccia, G
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali , 2007, DOI: 10.1478/c1a0701004
Abstract: Let k be a field of characteristic p > 0 and let F be a one dimensional commutative formal group over k. The endomorphisms of a k-algebra A that defines an action of F on A when A is isomorphic to the quotient B/pB, with B torsion-free Z-algebra, are studied.

Koszulness of binomial edge ideals
Marilena Crupi,Giancarlo Rinaldo
Mathematics , 2010,
Abstract: Let $G$ be a simple graph on the vertex set $V(G) = [n] = \{1,...,n\}$ and edge ideal $E(G)$. We consider the class of closed graphs. A closed graph is a simple graph satisfying the following property: for all edges $\{i, j\}$ and $\{k, \ell\}$ with $i < j$ and $k < \ell$ one has $\{j, \ell\}\in E(G)$ if $i = k$, and $\{i, k\}\in E(G)$ if $j = \ell$. We state some criteria for the closedness of a graph $G$ that do not depend necessarily from the labelling of its vertex set. Consequently, if $S = K[x_1,..., x_n, y_1,..., y_n]$ is a polynomial ring in $2n$ variables with coefficients in a field $K$, we obtain some criteria for the Koszulness of the quotient algebra $S /J_G$, where $J_G$ is the binomial edge ideal of $S$ i.e. the ideal generated by the binomials $f_{ij} = x_iy_j - x_jy_i$ such that $i
Squarefree monomial modules and extremal Betti numbers
Marilena Crupi,Carmela Ferro
Mathematics , 2014,
Abstract: Let K be a field and S a polynomial ring in a finite number of variables over K. Let F be a finitely generated graded free S-module. We examine some classes of squarefree monomial submodules of F. Hence, we focalize our attention on the Betti table of such classes in order to analyze the behavior of their extremal Betti numbers.
