Silvia Minoia, Angelo Petrozza, Olimpia D'Onofrio, Florence Piron, Giuseppina Mosca, Giovanni Sozio, Francesco Cellini, Abdelhafid Bendahmane, Filomena Carriero
BMC Research Notes , 2010, DOI: 10.1186/1756-0500-3-69
Abstract: To apply TILLING to tomato, a new mutant collection was generated in the genetic background of the processing tomato cultivar Red Setter by treating seeds with two different ethylemethane sulfonate doses (0.7% and 1%). An associated phenotype database, LycoTILL, was developed and a TILLING platform was also established. The interactive and evolving database is available online to the community for phenotypic alteration inquiries. To validate the Red Setter TILLING platform, induced point mutations were searched in 7 tomato genes with the mismatch-specific ENDO1 nuclease. In total 9.5 kb of tomato genome were screened and 66 nucleotide substitutions were identified. The overall mutation density was estimated and it resulted to be 1/322 kb and 1/574 kb for the 1% EMS and 0.7% EMS treatment respectively.The mutation density estimated in our collection and its comparison with other TILLING populations demonstrate that the Red Setter genetic resource is suitable for use in high-throughput mutation discovery. The Red Setter TILLING platform is open to the research community and is publicly available via web for requesting mutation screening services.Tomato (Solanum lycopersicum) is one of the most important vegetable plants in the world. Its fruits are end products both for the fresh market and food processing industry. Tomato presents a relatively small genome highly syntenic to others economically important Solanaceae species and was selected as a reference species for sequencing a Solanaceae genome. In addition to the availability of a number of genomic resources, including transcriptome [1-3] and metabolome [4], large collections of genetic resources are available to dissect the biochemical and the metabolic pathways in tomato [5]. Large EMS and fast neutron mutant collections, in the background of M82 tomato cultivar, have been generated and more then 3,000 phenotype alterations catalogued [6].

A time expanded version of the (Hitchcock-) transportation problem
Raffaele Mosca
European Transport Research Review , 2011, DOI: 10.1007/s12544-011-0056-3
Abstract: This paper considers a time expanded version of the classical (Hitchcock-) transportation problem. Certain quantities of goods are produced in the production facilities in each period of a planning horizon and also the demand values of the outlets are different for each time period. Moreover, the transportation costs from i to j also vary over time. The different planning periods are connected by the fact that goods may be stored at a facility or at an outlet to exploit cheaper transportation costs as long as the demand is met in every time period. We describe the problem by two models, showing that it can be solved in polynomial time by standard software packages. Then we describe some generalizations of the problem by adapting the two models, pointing out that each model seems to provide different benefits.
éducation multilingue et compétences plurilingues
Silvana Mosca
Synergies Italie , 2012,
Abstract: L’éducation linguistique des jeunes européens d’aujourd’hui s’inscrit dans un contexte socio-linguistique où le plurilinguisme individuel et le multilinguisme social sont de plus en plus fréquents. On présente ici le cas de projets élaborés par l’Ufficio scolastico regionale du Piémont, une région qui compte en moyenne 10% d’élèves non italophones. Le projet LITOS a abordé divers aspects socio-linguistiques à partir de deux enquêtes, à la maison et à l’école et Les langues des élèves . Confrontée au multilinguisme en présence, l’éducation linguistique a évolué, de nouveaux matériels didactiques comme par exemple les livrets bilingues et les CD rom Benvenuta/Benvenuto , ont été con us. L’enjeu a été également de former les enseignants et de mettre au point des curricula ciblés sur les compétences, par exemple le projet POSEIDON. Les documents de référence sont surtout les suivants: OECD PISA, QCER, Recommandation du Parlement Européen et du Conseil, Guide pour le développement et la mise en uvre de cursus pour une éducation plurilingue et interculturelle-Conseil de l’Europe.
Quantum Algorithms
Michele Mosca
Physics , 2008,
Abstract: This article surveys the state of the art in quantum computer algorithms, including both black-box and non-black-box results. It is infeasible to detail all the known quantum algorithms, so a representative sample is given. This includes a summary of the early quantum algorithms, a description of the Abelian Hidden Subgroup algorithms (including Shor's factoring and discrete logarithm algorithms), quantum searching and amplitude amplification, quantum algorithms for simulating quantum mechanical systems, several non-trivial generalizations of the Abelian Hidden Subgroup Problem (and related techniques), the quantum walk paradigm for quantum algorithms, the paradigm of adiabatic algorithms, a family of ``topological'' algorithms, and algorithms for quantum tasks which cannot be done by a classical computer, followed by a discussion.
The stable set polytope of ($P_6$,triangle)-free graphs and new facet-inducing graphs
Raffaele Mosca
Computer Science , 2014,
Abstract: The stable set polytope of a graph $G$, denoted as STAB($G$), is the convex hull of all the incidence vectors of stable sets of $G$. To describe a linear system which defines STAB($G$) seems to be a difficult task in the general case. In this paper we present a complete description of the stable set polytope of ($P_6$,triangle)-free graphs (and more generally of ($P_6$,paw)-free graphs). For that we combine different tools, in the context of a well known result of Chv\'atal \cite{Chvatal1975} which allows to focus just on prime facet-inducing graphs, with particular reference to a structure result on prime ($P_6$,triangle)-free graphs due to Brandst\"adt et al. \cite{BraKleMah2005}. Also we point out some peculiarities of new facet-inducing graphs detected along this study with the help of a software.
Re-Shoring and Resilience in Italy during and after the Crisis  [PDF]
Talamo Giuseppina, Sabatino Michele
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.85081
Abstract: Since 1990s, companies have started to shift their productions to the low-cost countries and this strategy is commonly known as offshoring. However, over the past years, the evidence shows that offshoring strategies may not continue to be beneficial for the organization’s companies activities. Consequently during the recent years, companies have begun to pay more attention to unquantifiable factors, such as the supply chain issue and strategy factors rather than simply relying on and the lowest price that in turn can mean the highest risk and high total cost. Having considered the discrepancy between the initially estimates cost of offshoring and those of actually occurred, companies are coming back through re-shoring strategies. In this paper, an overview of the main literature has been conducted to provide a better understanding of the term re-shoring. In the first section, various definitions and explanation of the concept of re-shoring will be presented. After that, the main motivations behind the re-shoring are discussed. The second part relies on the concept of resilience. We analyze resilience as a resource and response to the recent economic and financial crisis. In particular, this paper analyzes the role of economic resilience of the territories belonging to companies that have adopted offshoring strategies in the past and whether this has contributed to repatriation phenomena. In this regard, with the aid of recent data, we intend to understand the behavior of companies that have carried out re-shoring actions and their links with the economic resilience of the Italian regions. We also present whether there is a relationship at regional level between companies that have made re-shoring choices and the degree of economic resilience of a regional area. Finally, the critical considerations will be presented.

Evidence-Based Complementary and Alternative Medicine , 2007, DOI: 10.1093/ecam/nel085
Abstract: Verona's School of Homeopathic Medicine (www.omeopatia.org) organized a day of full immersion in the field of homeopathy, focusing on the validity of this much-debated discipline. There is widespread consensus in the medical community that evidence-based medicine is the best standard for assessing efficacy and safety of healthcare practices, and systematic reviews with strict protocols are essential to establish proof for various therapies. Students, homeopathic practitioners, academic and business representatives, who are interested in or curious about homeopathic practices attended the conference.
On a Class of Forward-Backward Stochastic Differential Systems in Infinite Dimensions
Giuseppina Guatteri
International Journal of Stochastic Analysis , 2007, DOI: 10.1155/2007/42640
Abstract: We prove that a class of fully coupled forward-backward systems in infinite dimensions has a local unique solution. After studying the regularity property of the solution, we prove that for a peculiar class of systems arising in the theory of stochastic optimal control, the solution exists in arbitrary large time interval. Finally, we investigate the connection between the solution to the systems and a stochastic optimal control problem.

Negri, Giuseppina;
Revista Brasileira de Ciências Farmacêuticas , 2005, DOI: 10.1590/S1516-93322005000200002
Abstract: diabetes mellitus comprises a group of ethiologically and clinically heterogeneous disorders with a common set of symptoms: excessive thirst and hunger, muscular weakness, weight loss, excessive urination and elevation of the blood glucose level among others. there has been a striking emergence of non-insulin-dependent diabetes mellitus as a major health problem in populations undergoing modernization of life-style, both in developed and underdeveloped nations. many species of plants have been used ethnopharmacologically or experimentally to treat symptons of diabetes mellitus. the high percentage of active plants probably reflects, at least in part, the great variety of possible active constituents and mechanisms of action. the wide diversity of chemical classes indicate a variety of mechanisms must be involved in the lowering of the blood glucose level. some of these compounds may have therapeutic potential, while others may produce hypoglycemia as a side-effect of their toxicity, specially hepatotoxicity. the present article is an actualized review of hypoglicemic medicinal plants and their active constituents.
