Heavy Neutrinos, Z' and Higgs Bosons at the LHC: New Particles from an Old Symmetry  [PDF]
Shaaban Khalil, Stefano Moretti
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.41002

A new era in particle physics is being spurred on by new data from the Large Hadron Collider. Non-vanishing neutrino masses represent firm observational evidence of new physics beyond the Standard Model. An extension of the latter, based on a SU(3)C × SU(2)L × U(1)Y × U(1)B-L symmetry, incorporating an established Baryon minus Lepton number invariance, is proposed as a viable and testable solution to the neutrino mass problem. We argue that LHC data will probe all the new content of this model: heavy neutrinos, an extra gauge boson emerging from spontaneous breaking of the additional gauge group at the TeV scale, onset by a new heavier Higgs boson, also visible at the CERN proton-proton collider. An even more exciting version of this model is the one exploiting Supersymmetry: firstly, it incurporates all its well-known benefits; secondly, it alleviates the flaws of its more minimal realisations. Finally, this model provides a credible cold Dark Matter candidate, the lightest sneutrino, detectable in both underground and collider experiments.

The Contribution of EEG to the Diagnosis of Dementia  [PDF]

Abstract: Changes induced by cerebrovascular damage (CVD) and amigdalo-hippocampal atrophy (AHC) on brain rhythmicity as?revealed?by scalp electroencephalography (EEG) were evaluated in a cohort of subjects with mild cognitive impairment (MCI) in order to detect different EEG patterns due to the vascular or degenerative impairment. All subjects underwent EEG recording and magnetic resonance imaging (MRI). EEGs were recorded at rest. Relative power was separately computed for delta, theta, alpha1, alpha2, and alpha 3 frequency bands. Increased delta power and decreased alpha2 power were associated with the load of cerebrovascular damage (CVD). Moreover, the theta/alpha 1 ratio could be a reliable index for the estimation of the individual extent of CV damage. No association of vascular damage was observed with alpha3 power. On the other side, moderate hippocampal atrophy was related to an increase of alpha2 and alpha3 frequency power ratio. Our results show that different EEG markers are associated to vascular dementia and Alzheimer’s disease (AD). EEG markers could be expression of different global network pathological changes, helping in differentiation of prodromal AD from vascular demented patients. MCI stated that EEG markers could have a prospective value in differential diagnosis between vascular and degenerative MCI.

Abstract: this article tries to answer the following questions: why are novels written in prose? why are they usually adventure stories? why, during the 18th century, there was the rise of the novel in europe? the aim is to enlarge the conception of the novel and the fields comprised by literary studies.
Todo canon, El canon
An??lisis filos?3fico , 2010,
Abstract: whenever expressions like "x is philosophical" appear in different questions and assorted statements, the reference to special kinds of actions, questions or demands are suggested by these uses. rabossi propounds a way for characterizing the sense of our using such expressions and, based on it, he states that philosophy, as it is accomplished from the last two centuries up to now, pretends to be a professional discipline but she cannot to be as such because the nature of its precepts (the canon). rabossi's arguments are examined and it is maintained that although they do not seem to be sufficient for the pursued conclusion, there are reasons to modify them such a way to come to that conclusion.

Confini domestici. Ruoli e immagini femminili nella pittura della controriforma
Massimo Moretti
Storia delle Donne , 2007,
Abstract: Looking out of the window or out of the door, peering beyond the property line, are considered blamed behaviours for the woman, as results in the domestic economy treaties and in the manual for the confession published between XV and XVI century. The symbiotic link between the woman and the door, background and semantic frame of the female condition, has been confirmed during the time by the paintings. In particular, the stories of Mary of Nazareth are able to define the scanning of the spaces and of the times of the Christian woman. As the illustrations of the XVI century obstetrician treaties show, the depiction of the “Nativity of Mary” is vehicle for the representation of the female life in the domestic settings in a significant moment as that concerning the birth of a baby. The pictorial and sculptural examples shown in this work, mark a double vision of the woman in the modern age in her relationship with her boundary. Doors and windows represent positive elements when are used to contain woman freedom; on the contrary, they are considered as negative ones when appear as woman means to fuel her curiosity.
Ports, Transport and Marine Culture in the Cities of Italy, for the 150th Anniversary of the Unification Porti, trasporti e cultura del mare nelle città d’Italia, per i 150 anni dall’Unità

Abstract: The celebrations for the 150th anniversary of the Unification of Italy also offer the opportunity to question the history and development of this country, particularly in reference to the maritime culture and the system of water transport. In a peninsular country like Italy, with its 7,500 km of waterfront, the presence of ports has always been crucial to economic growth and its success in international markets. But the second half of the twentieth century, cities and their ports have been gradually separated, resulting in situation of conflict and ongoing tensions. Only recently – following the Law 84, 1994 - new forms of ‘dialogue’ have allowed, on certain occasions, to restart political consultation on the development plans of the port areas and on improving the situation of urban areas close to ports. For all these reasons, the occasion of the 150th anniversary of the Unification of Italy can be a significant moment to resume the debate on the role of Italian ports in the history of our country, and possibly increase the potential that they may have, according to the positive and encouraging data of the entire maritime cluster in recent years, at least until the economic crisis of 2008. At the same time, the complex relationship port-city can be analyzed, with a view to mutual recognition of their needs and to the development of their activities in a framework of practical and effective, cooperative spirit, which requires both a greater mutual understanding as well as a more effective targeting to achieve a lasting and sustainable urban quality. The gradual economic globalization and market liberalization have led to a general increase in trade globally and in particular the Mediterranean has become a centre of traffic flows East-West and North-South. Italy, located in the middle of the Mediterranean basin, is now once again become the crossroads of the most important lines of goods and passengers connected world, experiencing a period of intense growth in maritime trade. Except for those ports with a strong presence of the cruise segment, which recorded growth rates of interest, the global economic crisis of 2008 has had very heavy in this sector (freight traffic to trucks and containers). This is also due to some historical gaps of the Mediterranean ports, such as the lack of rail connections to and from the ports, although Port Authorities are trying to bridge the gap both in terms of infrastructural interventions and environmental sustainability, through policies of sharing and coexistence between the port and the surrounding area and through a r
Polymerisation, basicity, oxidation state and their role in ionic modelling of silicate melts
R. Moretti
Annals of Geophysics , 2005, DOI: 10.4401/ag-3221
Abstract: In order to describe and quantify the reactivity of silicate melts, the ionic notation provided by the Temkin formalism has been historically accepted, giving rise to the study of melt chemical equilibria in terms of completely dissociated ionic species. Indeed, ionic modelling of melts works properly as long as the true extension of the anionic matrix is known. This information may be attained in the framework of the Toop-Samis (1962a,b) model, through a parameterisation of the acid-base properties of the dissolved oxides. Moreover, by combining the polymeric model of Toop and Samis with the group basicity concept of Duffy and Ingram (1973, 1974a,b, 1976) the bulk optical basicity (Duffy and Ingram, 1971; Duffy, 1992) of molten silicates and glasses can be split into two distinct contributions, i.e. the basicity of the dissolved basic oxides and the basicity of the polymeric units. Application to practical cases, such as the assessment of the oxidation state of iron, require bridging of the energetic gap between the standard state of completely dissociated component (Temkin standard state) and the standard state of pure melt component at P and T of interest. On this basis it is possible to set up a preliminary model for iron speciation in both anhydrous and hydrous aluminosilicate melts. In the case of hydrous melts, I introduce both acidic and basic dissociation of the water component, requiring the combined occurrence of H+ cations, OH- free anions and, to a very minor extent, of T-OH groups. The amphoteric behaviour of water revealed by this study is therefore in line with the earlier prediction of Fraser (1975).
Hikikomori. La solitudine degli adolescenti giapponesi / Hikikomori. La solitude des adolescents japonais Hikikomori / Japanese teenagers’ loneliness

Abstract: Il Giappone oggi rappresenta la terza potenza economica mondiale in cui il costo della vita è alto, il tasso di natalità basso e le patologie psichiche derivate da stress sono in forte aumento. Allarmante è il fenomeno hikikomori, una volontaria e ostinata forma di “ritiro sociale” (social withdrawal), di auto reclusione che si sviluppa nell’adolescenza e che nei casi più gravi dura anche più di dieci anni. L’eziologia del fenomeno è piuttosto complessa ma, tra le ipotesi plausibili avanzate, si parla di un disagio psichico dovuto ad una serie di fattori tra cui l’interdipendenza fra genitori e figli, la presenza di una figura materna iperprotettiva a fronte di un’assenza del padre e soprattutto il contesto sociale omologante, coartativo e frustrante. Si tratta di elementi in grado di generare nell’adolescente un angoscioso senso di inadeguatezza, alimentato dalla paura in cui il confronto con l’altro diventa insostenibile ed il silenzio la sola forma di comunicazione. Un disagio relazionale che conta nel Paese del Sol Levante più di un milione di adolescenti, ma che va diffondendosi anche negli Stati Uniti e nel Nord Europa.Le Japon représente aujourd'hui la troisième puissance économique mondiale, où le co t de la vie est élevé, le taux de natalité bas et les pathologies psychiques causées par le stress en forte augmentation. Le phénomène de l’hikikomori, une forme volontaire et obstinée de "retrait social" (social withdrawal), devient de plus en plus alarmant. Il s’agit d’une auto-réclusion qui se développe dans l'adolescence et qui, dans les cas les plus graves, peut durer plus de dix ans. L’étiologie du phénomène est plut t complexe mais, parmi les hypothèses plausibles avancées, l’on parle d’un trouble psychique du à une série de facteurs, parmi lesquels figurent l'interdépendance entre parents et enfants, la présence d'une figure maternelle hyper protectrice conjuguée à l’absence du père, et surtout le contexte social uniformisant, oppressif et frustrant. Il s'agit d'éléments capables de provoquer chez l'adolescent un sentiment angoissant d'inadéquation, alimenté par la peur et dans lequel la comparaison avec l'Autre devient insoutenable et le silence la seule forme de communication. C’est un trouble relationnel qui concerne plus d'un million d'adolescents au Pays du Soleil Levant, et qui commence également à se répandre aux états-Unis et en Europe du Nord.Japan represents today the third world economic power with a high cost of life, a low birth-rate and a growth in psychological stress. It is quite worrying the phenomenon called “hikikomori”: i
