Semileptonic KL Decays at NA48

Preliminary results on KL->pi e nu(gamma) decays collected by the NA48 detector at the CERN SPS are reported. Using a sample of 6.8 X 10^6 reconstructed events BR(Ke3) = 0.4010+-0.0028+-0.0035 was obtained. From the branching ratio the value of |Vus|= 0.2187+-0.0028 was extracted. The same data sample has provided also a high precision measurement of the slope lambda+ of the form factor of the Ke3 decay. Investigating the Ke3gamma decay, from a sample of 18977 reconstructed events, BR(Ke3gamma)/BR(Ke3) = (0.964+-0.008+0.012-0.011)% was determined.Comment: 4 pages, 2 figures.

A study of nuclear effects in ν\nu interactions with the NOMAD detector

Nuclear effects in \numucc interactions with carbon nuclei have been studied by using backward going protons and $\pi^-$. Detailed analyses, of the momentum distributions and of the production rates, have been carried out in order to understand the mechanism producing these particles. The backward proton data have been compared with the predictions of the reinteraction and the short range correlation models.Comment: 8 pages, 7 figures, to be published in Proc. of NUINT01, The First International Workshop on Neutrino-Nucleus Interactions in the Few GeV Region; December 13-16 2001, KEK Tsukuba, Japa

NA48 Results on Kaon and Hyperon Decays Relevant to |V_us|

New results from the NA48 experiment on kaon and hyperon decays relevant to |V_us| are reported here. For charged kaons we present measurements of BR(K+- -> pi0 e+- nu) and BR(K+- -> pi0 mu+- nu). On neutral kaon decays we report the measurements of BR(K_L -> pi+ pi-) and of K_L -> pi+- mu-+ nu form factors slopes. For hyperons we present results on the BR(Xi0 -> Sigma+ e- nu_e).Comment: 4 pages, 3 figures, to appear in the proceedings of CKM 2006, 4th International Workshop on the CKM Unitarity Triangle, December 12-16, 2006 Nagoya, Japa

THE INTELLECTUAL CAPITAL STATEMENT AND THE BALANCED SCORECARD AS COMPLEMENTARY MODELS IN MEASURING FIRM INTANGIBLES

The purpose of this paper is to examine the role of two different new management tool, the Balanced Scorecard (BSC) and the Intellectual Capital Report (ICR) in managing and reporting intangibles. Unlike the majority of IC scholars the author, and consistently with Bukh et al. (2005), the author starts from the idea that BSC and ICR are not alternative, but complementary tools in measuring intangibles, addressing different needs for firms that measure, manage and report intangibles. The research hypothesis of the paper will be demonstrated through the analysis of a case study of an Italian group which use both intangibles' reporting systems. A case study methodology has been chosen, given that it is widely used by researchers and provide the basis for the application of ideas and extension of methods (Yin, 1994). Intercos group has been chosen to test the research hypothesis, since it makes use of both models in measuring and reporting intangibles. The study of the case Intercos group found evidence that the two types of extended reporting are different and yet complementary and that both tools are necessary for firm in measuring IC, since they address different aims. This includes therefore a marked difference in use of indicators, given that IC indicators in the ICR have to support the overall aims derived by company's strategy, while BSC indicators provides a breakdown of strategic goals with respect to profitability, growth etc. The contribution of the paper to the IC literature is to extend the findings of the Bukh et al.'s (2003) study, investigating the hypothesis (and finding evidence) that BSC and ICR are complementary in reporting intangibles in an Italian group. Implications of the paper are for company's manager, who increase the awareness that they have at their disposal two management tools, with address different aims, to manage intangibles.Intellectual capital report, balanced scorecard, complementary models

COMPARING EXPERIENCES IN REPORTING INTELLECTUAL CAPITAL IN UNIVERSITIES

The paper focuses on the intellectual capital (IC) report in universities, a relevant theme actually for the growing interest in applying an IC approach in managing universities. The paper compares the experiences in reporting IC of two different university institutions, the Autonomous University of Madrid (UAM) and the Austrian Universities, to highlight pros and cons of the two different IC models employed. In order to compare these two experiences, firstly we analyzed, through a literature review, the state-of-the-art in measuring and reporting IC, then we focus on the IC measurement models used as framework by the two institution, finally we turned our attention to the IC reports issued by the two universities. Both experiences presented refer to advanced IC measurement models, but both suffer of some limits in applying the models in practice. Like all measurement and management systems that deal with knowledge-based processes, Austrian and UAM's IC reports face the methodological problems of measuring non-physical processes and outputs. In detail, Austrian IC reports lack of qualitative indicators, UAM's IC report lacks of efficiency-related and activities-related indicators.The main research limit is that the theoretical comparison has been carried out on two experiences, due to the lack of awareness of IC relevance in managing universities. The establishment of an ad hoc IC measurement model for universities could have both internal and external benefits. As regards the policy implications, Government, ranking universities by their IC, can get information about their strengths and weaknesses and using it to reallocate resources. This study contributes to broaden the research community's understanding about a relevant management (internal) and communication (external) universities' tool, the IC report, through the examination of two real life European universities experiences in disclosing intangibles. To the best of our knowledge, this is the first paper that focuses on comparing the two best university practices in reporting IC.Intellectual capital, universities

Variations on Noetherianness

In constructive mathematics, several nonequivalent notions of finiteness exist. In this paper, we continue the study of Noetherian sets in the dependently typed setting of the Agda programming language. We want to say that a set is Noetherian, if, when we are shown elements from it one after another, we will sooner or later have seen some element twice. This idea can be made precise in a number of ways. We explore the properties and connections of some of the possible encodings. In particular, we show that certain implementations imply decidable equality while others do not, and we construct counterexamples in the latter case. Additionally, we explore the relation between Noetherianness and other notions of finiteness.Comment: In Proceedings MSFP 2016, arXiv:1604.0038

Laser-Accelerated proton beams as diagnostics for cultural heritage

This paper introduces the first use of laser-generated proton beams as diagnostic for materials of interest in the domain of Cultural Heritage. Using laser-accelerated protons, as generated by interaction of a high-power short-pulse laser with a solid target, we can produce proton-induced X-ray emission spectroscopies (PIXE). By correctly tuning the proton flux on the sample, we are able to perform the PIXE in a single shot without provoking more damage to the sample than conventional methodologies. We verify this by experimentally irradiating materials of interest in the Cultural Heritage with laser-accelerated protons and measuring the PIXE emission. The morphological and chemical analysis of the sample before and after irradiation are compared in order to assess the damage provoked to the artifact. Montecarlo simulations confirm that the temperature in the sample stays safely below the melting point. Compared to conventional diagnostic methodologies, laser-driven PIXE has the advantage of being potentially quicker and more efficien

Additional development of large diameter carbon monofilament

The chemical vapor process for preparing a large diameter carbon-base monofilament from a BCl3, Ch4 and H2 gas mixture with a carbon substrate fiber was studied. The effect of reactor geometry, total gas flows and deposition temperature on the tensile strength of the monofilament were investigated. It was noted that consistent results could only be obtained when the carbon substrate fiber was cleaned. The strength of the monofilament was found to depend on the highest temperature and the temperature profile of the monofilament in the reactor. The strength of monofilament produced in the dc and RF reactors were found to be similar and similar alloy compositions in the monofilament were attained when the same gas ratios were used. The tensile strength of the monofilament at 500 C was found to be 60 to 70% of the room temperature tensile strength. No degradation was noted after exposure to molten aluminum
