Post 1990s Dance Theatre and (the idea of) the Neutral
No full textPhDThe thesis focuses on the concept of neutrality in the works of contemporary
European (post 1990s) choreographers. While broad ideas around neutrality are
considered, the thesis primarily engages with Roland Barthes’ definition of
neutrality as a structural term: 'every inflection that, dodging or baffling the
paradigmatic, oppositional structure of meaning, aims at the suspension of the
conflictual basis of discourse'. I argue that the minimalist work of Judson
Church, New York City, is anticipating the interest in the neutral that will more
strongly formulate itself in dance theatre after the 1990s. In the first chapter on
Jérôme Bel, the concept of neutrality is introduced as a general idea, together with
its inherent problem. The 'problem' is not that this or that element that Bel
chooses cannot be perceived as neutral, but that neutral or stage zero can never be
neutral enough. The second chapter, dedicated to the work of Thomas Lehmen,
explores the idea of 'neutralization' in relation to the notion of the self in
Lehmen's performance, where 'It is not I or you who lives: 'one' (une vie) lives in
us' (P. Hallward). In the third chapter I argue that in Raimund Hoghe’s
performances, love is conceived essentially as a balance between narcissism and
pure object-love – as a neutral state. The fourth chapter, on Croatia’s BADco.,
gravitates around the ways in which group processes function, arguing that the
idea of the neutral is located in the ‘invisible hand’ of emergence. The thesis shifts
academic performance analysis towards a more concept-based approach,
unpicking and/or constructing timeless, abstract and broad concepts and ideas that
the work of these choreographers resonates with

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Cosmological constraints from galaxy clustering in the presence of massive neutrinos
No full textThe clustering ratio is defined as the ratio between the correlation function and the variance of the smoothed overdensity field. In ΛCDM cosmologies without massive neutrinos, it has already been proven to be independent of bias and redshift space distortions on a range of linear scales. It therefore can provide us with a direct comparison of predictions (for matter in real space) against measurements (from galaxies in redshift space). In this paper we first extend the applicability of such properties to cosmologies that account for massive neutrinos, by performing tests against simulated data. We then investigate the constraining power of the clustering ratio on cosmological parameters such as the total neutrino mass and the equation of state of dark energy. We analyse the joint posterior distribution of the parameters that satisfy both measurements of the galaxy clustering ratio in the SDSS-DR12, and the angular power spectra of CMB temperature and polarization anisotropies measured by the Planck satellite. We find the clustering ratio to be very sensitive to the CDM density parameter, but less sensitive to the total neutrino mass. We also forecast the constraining power the clustering ratio will achieve, predicting the amplitude of its errors with a Euclid-like galaxy survey. First we compute parameter forecasts using the Planck covariance matrix alone, then we add information from the clustering ratio. We find a significant improvement on the constraint of all considered parameters, and in particular an improvement of 40% for the CDM density and 14% for the total neutrino mass
Precision measurements of B[psi(3686) -> pi(+)pi(-)J/psi] and B[J/psi -> l(+)l(-)]
No full text<p>Based on (106.41 +/- 0.86) x 10(6) psi(3686) events collected with the BESIII detector at the BEPCII collider, the branching fractions of psi(3686) -> pi(+)pi(-)J/psi, J/psi -> e(+)e(-), and J/psi -> mu(+)mu(-) are measured. We obtain B[psi(3686) -> pi(+)pi(-)J/psi] = (34.98 +/- 0.02 +/- 0.45)%, B[J/psi -> e(+)e(-)] = (5.983 +/- 0.007 +/- 0.037)%, and B[J/psi -> mu(+)mu(-)] = (5.973 +/- 0.0007 +/- 0.038)%. The measurement of B[psi(3686) -> pi(+)pi(-)J/psi] confirms the CLEO-c measurement, and is apparently larger than the others. The measured J/psi leptonic decay branching fractions agree with previous experiments within one standard deviation. These results lead to B[J/psi -> l(+)l(-)] = (5.978 +/- 0.005 +/- 0.040)% by averaging over the e(+)e(-) and mu(+)mu(-) channels and a ratio of B[J/psi -> e(+)e(-)]/B[J/psi -> mu(+)mu(-)] = 1.0017 +/- 0.0017 +/- 0.0033, which tests e- mu universality at the four tenths of a percent level. All the measurements presented in this paper are the most precise in the world to date.</p>

Scenography and new media technologies: history, educational applications and visualization techniques
No full textThe endemic presence of digital technology is responsible for numerous changes in contemporary Western societies. This study examines the role of multimedia within the field of theatre studies, with particular focus on the theory and practice of theatre design and education. In the cross-disciplinary literature review, I investigate such primary elements of contemporary media as interactivity, immersion, integration and hyper-textuality, and explore their characteristics in the performing arts before and during the digital epoch. I also discuss various IT applications that transformed the way we experience, learn and co-create our cultural heritage. In order to illustrate how computer-generated environments could change the way we perceive and deliver cultural values, I explore a suite of rapidly-developing communication and computer-visualization techniques, which enable reciprocal exchange between viewers, theatre performances and artefacts. I analyze novel technology-mediated teaching techniques that attempt to provide a new media platform for visually-enhanced information transfer.
My findings indicate that the recent changes towards the personalization of knowledge delivery and also towards student-centered study and e-learning necessitated the transformation of the learners from passive consumers of digital products to active and creative participants in the learning experience. The analysis of questionnaires and two case studies (the THEATRON and the VA projects) demonstrate the need for further development of digital-visualization techniques, especially for studying and researching scenographic artefacts. As a practical component of this thesis, I have designed and developed the Set-SPECTRUM educational project, which aims to strengthen the visual skills of the students, ultimately enabling them to use imagery as a creative tool, and as a means to analyze theatrical performances and artefacts. The 3D reconstruction of Norman Bel Geddes' set for The Divine Comedy, first of all, enables academic research of the artefact, exposing some hitherto unknown design-limitations in the original set-model, and revealing some construction inconsistencies; secondly, it contributes to educational and creative practices, offering an innovative way to learn about scenography. And, thirdly, it fills a gap in the history of the Western theatre design.
This study attempts to show that when translated into digital language, scenographic artefacts become easily retrievable and highly accessible for learning and research purposes. Therefore, the development of such digital products should be encouraged, but care should also be taken to provide the necessary training for users, in order to realize the applications' full potential
The economic and fiscal impacts of Hurricane Sandy in New Jersey, a macroeconomic analysis
No full textThis report estimates the macroeconomic and fiscal impacts of Hurricane Sandy on the economy of New Jersey using the R/ECON™ forecasting model of the state’s economy. The model consists of more than 250 quarterly time-series equations and 30 employment sectors.The analysis takes into account both the economic losses resulting from the hurricane and the offsetting positive economic impacts associated with recovery and reconstruction spending in the months and years following the storm.However, the estimates of impacts depend upon the restoration expenditures actually being made. If the funds for these restoration and recovery expenditures are not made available, the offsetting positive impacts to the economy will not occur and the New Jersey economy will be significantly damaged. See Section 3 for estimates of the negative impacts if restoration expenditures are not made.This report was published as Issue Paper Number 34, January 2013, in Rutgers Regional Report
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
