Few-body insights of multiquark exotic hadrons

2018

In this contribution we discuss the adequate treatment of the $4-$ and $5-$body dynamics within a constituent quark framework. We stress that the variational and Born-Oppenheimer approximations give energies rather close to the exact ones, while the diquark approximation might be rather misleading. Hall-Post inequalities provide very useful lower bounds that exclude possible stable states for some mass ratios and color wave functions.

Ortho -Functionalized Aryltetrazines by Direct Palladium-Catalyzed C−H Halogenation: Application to Fast Electrophilic Fluorination Reactions

2016

International audience; A general catalyzed direct C-H functionalization of s-tetrazines is reported. Under mild reaction conditions, N-directed ortho-C-H activation of tetrazines allows the introduction of various functional groups, thus forming carbon-heteroatom bonds: C-X (X=I, Br, Cl) and C-O. Based on this methodology, we developed electrophilic mono- and poly-ortho-fluorination of tetrazines. Microwave irradiation was optimized to afford fluorinated s-aryltetrazines, with satisfactory selectivity, within only ten minutes. This work provides an efficient and practical entry for further accessing highly substituted tetrazine derivatives (iodo, bromo, chloro, fluoro, and acetate precurso…

Estimation of wind velocity over a complex terrain using the Generalized Mapping Regressor

2010

Abstract Wind energy evaluation is an important goal in the conversion of energy systems to more environmentally friendly solutions. In this paper, we present a novel approach to wind speed spatial estimation on the isle of Sicily (Italy): an incremental self-organizing neural network (Generalized Mapping Regressor – GMR) is coupled with exploratory data analysis techniques in order to obtain a map of the spatial distribution of the average wind speed over the entire region. First, the topographic surface of the island was modelled using two different neural techniques and by exploiting the information extracted from a digital elevation model of the region. Then, GMR was used for automatic …

Univariate and multivariate properties of wind velocity time series

2009

We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.

Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks

2016

In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …

The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …

2021

The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…

Confronto tra due impieghi compilatori di un testo di Marciano (A proposito del recente recupero di un manoscritto di Lauro Chiazzese)

2019

Moving from some perspectives of investigation emerged during the Roman law Seminar on ‘Orizzonti della critica testuale fra tradizione e nuovi indirizzi’, held in Palermo (16 november 2018), the A. examines a ‘comparison’ between texts, respectively, of Justinian’s Institutes and Digest [I. 2.11.5 = Marc. 4 inst. D. 29.1.22], analyzed by Lauro Chiazzese in the manuscript discovered and recently published by Giuseppe Falcone [Confronti testuali. Contributo alla dottrina delle interpolazioni giustinianee, Parte speciale (Materiali), collana Fonti - 4 degli Annali del Seminario giuridico dell’Università di Palermo, Torino 2018].

Współdziałanie nauczycieli i rodziców w eliminowaniu trudności wychowawczych

2013

Trudności wychowawcze z uczniami klas młodszych stanowią jeden z najważniejszych problemów współczesnej edukacji Zagadnienie to jest bardzo istotne, gdyż coraz więcej dzieci sprawia rożnego rodzaju problemy, z którymi nie mogą poradzie sobie zarowno rodzice, jak i nauczyciele W artykule zostaną przedstawione wyniki badan na temat współpracy nauczycieli z rodzicami wraz z propozycjami eliminowania negatywnych zachowań u uczniów Ważne jest przy tym, aby nauczyciele wspólnie z rodzicami podejmowali pracę z dziećmi sprawiającymi trudności wychowawcze

Rola problemów społecznych w procesie decyzyjnym polskiego wyborcy w 2015 roku

2017

W 2015 r. odbyły się dwie ważne elekcje: obywatele wybierali najpierw prezydenta kraju, później parlament. Decyzja o tym, na kogo oddać głos, bardzo często łączy się z proponowanymi przez kandydatów rozwiązaniami palących problemów społecznych. Aby dowiedzieć się, co kierowało wyborcami oraz co zachęciło ich do zagłosowania w określony sposób, warto przeanalizować propozycje społeczne partii i kandydatów na urząd Prezydenta, a także zapytać o opinię określoną grupę respondentów.
