Measurement of WZ and ZZ production in pp collisions at 8 TeV in final states with b-tagged jets with the CMS experiment

In this note we present a measurement of the VZ (V=W,Z) production cross section in proton-proton collisions at $\sqrt{s}=$8 TeV in the VZ$\rightarrow$V$b\bar{b}$ decay mode with V$=$Z$\rightarrow (\nu\bar{\nu}$,$\ell\ell$), V$=$W$\rightarrow \ell{\nu}$, ($\ell=e,\mu$). The results are based on data corresponding to an integrated luminosity of 18.9 fb$^{-1}$ collected with the CMS experiment. The process is observed for the first time in this particular final state with a significance exceeding six standard deviations ($\sigma$). The measured cross sections are consistent with the predictions of NLO calculations.Comment: 4 pages, 8 figures, proceeding for the Moriond 2014 EW sessio

Singularities of slice regular functions

Beginning in 2006, G. Gentili and D.C. Struppa developed a theory of regular quaternionic functions with properties that recall classical results in complex analysis. For instance, in each Euclidean ball centered at 0 the set of regular functions coincides with that of quaternionic power series converging in the same ball. In 2009 the author proposed a classification of singularities of regular functions as removable, essential or as poles and studied poles by constructing the ring of quotients. In that article, not only the statements, but also the proving techniques were confined to the special case of balls centered at 0. In a subsequent paper, F. Colombo, G. Gentili, I. Sabadini and D.C. Struppa (2009) identified a larger class of domains, on which the theory of regular functions is natural and not limited to quaternionic power series. The present article studies singularities in this new context, beginning with the construction of the ring of quotients and of Laurent-type expansions at points other than the origin. These expansions, which differ significantly from their complex analogs, allow a classification of singularities that is consistent with the one given in 2009. Poles are studied, as well as essential singularities, for which a version of the Casorati-Weierstrass Theorem is proven.Comment: 25 pages, 1 figur

Displaying Lives: the Narrative of Objects in Biographical Exhibitions

Biographical exhibitions are a museum practice that asks for critical consideration. Grounding the argument in critical theory, social studies and museum theory, the article explores the narrative function of objects in biographical exhibitions by addressing the social significance of objects in relation to biography and their relevance when presented into an exhibition display. Central is the concept of objects as ‘biographical relics’ that are culturally fetishized in biographical narratives. This raises questions about biographical reliability and the cultural role that such objects plays in exhibition narratives as bearers of reality and as metonymical icons of the biographical subject. The article considers examples of biographical exhibitions of diverse figures such as Gregor Mendel, Madame de Pompadour and Roland Barthes, and the role that personal items, but also portraits and photographs, play in them

The Constraint Equations in the Presence of a Scalar Field - the Case of the Conformal Method with Volumetric Drift

In this paper we establish the existence in low dimensions of solutions to the constraint equations in the case of the conformal system recently proposed by David Maxwell, with the added presence of a scalar field and under suitable smallness assumptions on its parameters.Comment: 46 page

College Student Perceptions of ADHD: Links Between Prior Knowledge and Stigma

Attention deficit hyperactivity disorder (ADHD) is characterized by persistent inattention, which might or might not accompany hyperactivity and impulsivity, that noticeably interferes with functioning and development in at least two settings. It is a commonly diagnosed childhood mental health disorder. Public knowledge and attitudes towards ADHD are an important consideration for those who are going to potentially be working with that population. Research has shown older children and parents may attribute ADHD behavior to poor social skills or immaturity. Teachers often report feeling unprepared to have a student with ADHD and would like more training. Some research has shown the perpetuation of common misconceptions of ADHD by parents and teachers. This research sought to determine if there was a correlation between knowledge of ADHD and stigma towards individuals with ADHD and to determine if students majoring in psychology differed from their peers on knowledge about ADHD or attitudes towards individuals with ADHD. After surveying 131 students from a faith-based, private university in Virginia, it was found that those majoring in psychology did not have significant differences in knowledge of ADHD or stigma towards people with ADHD when compared to students in other majors. Both knowledge and stigma scores were high across groups and no significant correlation between knowledge and attitudes was found. Findings have implications for university students diagnosed with ADHD and administrators working to reduce the stigma of ADHD on campus
