    Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV

    No full text
    The 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

    CLARIS LPB WP9: Water resources in La Plata Basin in the context of climate change

    No full text
    The WP9, Water resources in La Plata Basin (LPB) in the context of climate change, is part integrant of the Subproject 4, Socio-economic scenarios and adaptation/prevention strategies, that share with WP8, Land use change, agriculture and socio-economic implications, the technical, social and environmental responsibility to create tools to allow evaluate the impact of climate change scenarios at LPB. In a more comprehensive approach, WP9 addresses issues of crucial importance for the region such as the flood risks, the river navigation (problems induced by sediment transport), the hydropower production and the ecological systems in wetlands. The economic implications and adaptation strategies will be suggested. Collaborations with stakeholders such as CIC (Comité Intergubernamental Coordinador de los Países de la Cuenca del Plata), hydropower dams (South Brazil), and national water resources ministries will ensure the dissemination of the results to local and regional actors

    C*-algebras have a quantitative version of Pełczyński's property (V)

    No full text
    summary:A Banach space XX has Pełczyński's property (V) if for every Banach space YY every unconditionally converging operator T ⁣:XYT\colon X\to Y is weakly compact. H. Pfitzner proved that CC^*-algebras have Pełczyński's property (V). In the preprint (Krulišová, (2015)) the author explores possible quantifications of the property (V) and shows that C(K)C(K) spaces for a compact Hausdorff space KK enjoy a quantitative version of the property (V). In this paper we generalize this result by quantifying Pfitzner's theorem. Moreover, we prove that in dual Banach spaces a quantitative version of the property (V) implies a quantitative version of the Grothendieck property

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Curated Database of Pathological Speech Parameters

    No full text
    The cured database was built in (Fernandes, et al., 2019) taking into account the sounds available in the Saarbrucken Voice Database (SVD) (Barry, et al.). Included in this cured database were 19 diseases and control subjects. It has a total number of samples of 707 pathological subjects (distributed by the various diseases) and 194 control subjects, and for each subject there is a sentence and three vowels /a/, /i/, and /u/, each vowel with three tones: high, low and normal. In the cured database there is an initial page containing the id of each subject, the age, gender, characterisation group that corresponds to the subject and the abbreviation that is used for this group. For each group there are 3 pages. The first page of each group includes the parameters: absolute jitter, relative jitter, absolute shimmer, relative shimmer, HNR, NHR and autocorrelation. For each subject, the subject's age and gender are also identified, as well as the vowel and tone to which the parameter corresponds. The second page lists the MFCCs of the recorded sentences, in this there are 13 cepstral coefficients throughout the sentence, making a total of 50 sentence segments. Finally, the third page lists the MFCCs for the vowels. This parameter was also extracted with 13 cepstral coefficients for each vowel and tone. However, for the vowels the sound was not segmented as happened for the phrase, extracting a value per coefficient for the whole sound.   References Barry, B., Just, M., Pützer, M., Caradonna, R., Dressler, C., Erriquez, A., . . .
