Helicity amplitude analysis of χ cJ → ϕϕ
No full textAbstract Using (447.9 ± 2.3) million ψ(3686) events collected with the BESIII detector, the decays of χ cJ → ϕϕ (J = 0, 1, 2) have been studied via the decay ψ(3686) → γχ cJ . The branching fractions of the decays χ cJ → ϕϕ (J = 0, 1, 2) are determined to be (8.59 ± 0.27 ± 0.20) × 10 −4, (4.26 ± 0.13 ± 0.15) × 10 −4, and (12.67 ± 0.28 ± 0.33) × 10 −4, respectively, which are the most precise measurements to date. From a helicity amplitude analysis of the process ψ(3686) → γχ cJ , χ cJ → ϕϕ, ϕ → K + K − , the polarization parameters of the χ cJ → ϕϕ decays are determined for the first time
Recent advancements of landslide hydrology
No full textOccurrence of rainfall-induced landslides is increasing worldwide, owing to land use and climate changes. Although the connection between hydrology and rainfall-induced landslides might seem obvious, hydrological processes have been only marginally considered in landslide research for decades. In 2016, an advanced review paper published in WIREs Water [Bogaard and Greco (2016), WIREs Water, 3(3), 439–459] pointed out several challenging issues for landslide hydrology research: considering large-scale hydrological processes in the assessment of slope water balance; including antecedent hydrological information in landslide hazard assessment; understanding and quantifying the feedbacks between deformation and infiltration/drainage processes; overcoming the conceptual mismatch of soil mechanics models and hydrological models. While little progress has been made on the latter two issues, a variety of studies have been published, focusing on the role of hydrological processes in landslide initiation and prediction. The importance of the identification of the origin of water to understand the processes leading to landslide activation is largely acknowledged. Techniques and methodologies for the definition of landslide catchments and for the assessment of landslide water balance are progressing fast, often considering the hydraulic effect of vegetation. The use of hydrological information in landslide prediction models has also progressed enormously. Empirical predictive tools, to be implemented in early warning systems for shallow landslides, benefit from the inclusion of antecedent soil moisture, extracted from different sources depending on the scale of the prediction, leading to significant improvement of their predictive skill. However, this kind of information is generally still missing in operational LEWS. This article is categorized under: Science of Water > Hydrological Processes.Water Resource
Helicity amplitude analysis of χ→ ϕϕ

The branching fractions of the decays χ→ ϕϕ (J = 0, 1, 2) are determined to be (8.59 ± 0.27 ± 0.20) × 10, (4.26 ± 0.13 ± 0.15) × 10, and (12.67 ± 0.28 ± 0.33) × 10, respectively, which are the most precise measurements to date. From a helicity amplitude analysis of the process ψ(3686) → γχ, χ→ ϕϕ, ϕ → KK, the polarization parameters of the χ→ ϕϕ decays are determined for the first time.[graphic not available: see fulltext
Republican amphorae in the Auvergne central France
No full textThis thesis studies Republican amphoraefrom late Iron age (c. 200-1 BC) sites from the Auvergne (central France). The morphology, dating and contents of Greco-Italic, Dressel 1 and Lamboglia 2 amphorae, and the morphology of Republican amphoraefrom Mediterranean shipwrecks are reviewed. The morphology of 28 Republican amphorae assemblages from
the Auvergne are described in detail and compared with 44 assemblages from Western Europe. A detailed programme of fabric analysis,using thin-sectioning, of 408 rim sherds,has created96 fabric groups,many of which have been assigned to specific kilns. The distribution of Republican
amphorae in the Auvergne and for the whole of France is studied and discussed. The role of amphorae in socio-economic change,the accessto amphorae, the deposition of amphorae and the importation of other Mediterranean imports (Campanian wares,mortaria andpate claires) in the Auvergne is addressed. Assemblages of Republican amphorae stamps from the Auvergne and the rest of Franceare compared by analysing the types of stamps,their placement, stamping rates and their place of origin. The Republican wine trade to the Auvergne started during the second century BC when small numbers of Greco-Italic amphoraewere imported and the large-scale importation of Dressel I amphorae occurred after c.150/140BC. A high proportion of the amphoraecame from the Etrurian kilns of Albinia and Cosa. Republican amphoraewere widely distributed in the Auvergne during the second century BC with 203 findspots and are found in large numbersat several sites
Intersection of art, science and architecture: stochastic architecture compositions of eventualist theory
No full textThe paper illustrates the first application in a real architectural context of samples of Stochastic Tiles, based on paintings by Sergio Lombardo, an Italian artist, a leading figure of the Roman avant-garde in the sixties who is still active today. In the eighties he elaborated the innovative aesthetic theory of Eventualism .
Stochastic Architectural Composition is an experimental research activity, carried on by the author, that deals with complexity and random processes in architecture, according to the methods and procedures developed by Lombardo, as well as to the new ideas of creativity and the artwork delineated by the Eventualist theory. Some experimental projects and built architectures, designed by the author, are also presented in the article
Startup Ecosystems. Components for an interpretative Model and International Benchmarks
No full textThis book analyzes the components of the startup ecosystem, including the characteristics that can favor or disadvantage the development of new innovative ventures. The author believes it is essential to identify crucial variables of start-up ecosystems that have a context-specific influence on the well-being and development of startups. In this regard, the book analyzes the concept of the start-up ecosystem both from the point of view of scholars and professionals. The author then deals with the diverse approaches to studying startup ecosystems, which have over the years become increasingly complex, and less linear, making systematization indispensable. The author provides therefore a classification with a transversal logic with respect to this diversity of contributions in the literature. The main theoretical contributions to start-up ecosystems are grouped according to the attention they place on three different variables: territorial contexts, resources, and actors. The author alsopresents qualitative, interview-based, research using narrative analysis mode to understand the three variables.
The work provides, on the one hand, the proposal of a framework as a theoretical interpretative model useful both for the description of the fundamental components of the start-up ecosystem, and also useful for giving a boost to future research. On the other hand, the book also presents evidence of a practical nature useful to support and guide the choices of startup founders and of managers of companies and institutions that orbit within start-up ecosystems
Observation of chi(cJ) -> Lambda(Lambda)over-bar(eta)
No full textBy analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of chi(cJ) -> Lambda(Lambda) over bar (eta) (J = 0, 1, and 2) are observed for the first time with statistical significances of 13.9 sigma, 6.7 sigma, and 8.2 sigma, respectively. The product branching fractions of psi(3686) -> gamma chi(cJ) and chi(cJ) -> Lambda(Lambda) over bar (eta) are measured. Dividing by the world averages of the branching fractions of psi(3686) -> gamma chi(cJ), the branching fractions of chi(cJ) -> Lambda(Lambda) over bar (eta) decays are determined to be (2.31 +/- 0.30 +/- 0.21) x 10(-4), (5.86 +/- 1.38 +/- 0.68) x 10(-5), and (1.05 +/- 0.21 +/- 0.15) x 10(-4) for J = 0, 1 and 2, respectively, where the first uncertainties are statistical and the second systematic
