Status of Detector Requirements for FCC-ee
No full textFor the future lepton collider FCC-ee, different detector designs are studied and optimized. They must first achieve the required performances for heavy-flavour tagging, particle identification, tracking and particle-flow reconstruction, as well as lepton, jet, missing energy and angular resolutions, needed to successfully develop the very broad FCC-ee physics program, and exploit the extremely high statistical precision offered by this future collider. On top of that, they must all satisfy the constraints imposed by the challenging interaction region layout. FCC feasibility studies are being now carried out, using benchmark physics processes to determine, via appropriate simulations, the requirements on the detector performance which can guarantee that the systematic uncertainties of the measurements will be lowered as far as possible with the tiny statistical uncertainties as the target. Additionally, the potential for discovering very weakly coupled new particles, in decays of Z or Higgs bosons, motivates dedicated detector designs that would increase the efficiency for reconstructing the unusual signatures of such processes. These studies are crucial input to the further optimization of the two concepts described in the FCC-ee Conceptual Design Report, CLD and IDEA, and to the development of new concepts which might prove to be even better suited for the FCC-ee physics program
Sustainability in the Energy System and in the Industrial System
No full textWith the term “industrial system”, one refers to the set of processes, technologies, and infrastructure used to produce goods and services in a society. This includes the factories, machinery, and all the equipment used to manufacture products, as well as the transportation and distribution systems that deliver the products to customers
Comments on the CDF 88-89 di-lepton top candidate event
No full textCDF reported a possible top candidate event from their 988/89 run. The event was interpreted and reconstructed as pp→tt→ W + W + jet(b) + + jet(B) + Μ.(B) by some authors. We study the structure of the event to see whether this interpretation is likely. © 1994 Società Italiana di Fisica

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
