Jules Laforgue. Tradizione e traduzioni
No full textThe journey in which Velez takes us by the hand surprises for its ability to reveal the man-poet behind the mask of sarcasm, as well as Laforgue's vocation to seek new forms of expression of reality starting from a re-semanticized past towards a future that exists/does not exist in the dream of the liberated mind. A journey that leads him to ask himself why, one hundred and fifty years after his death, this French author is still translated and studied in Italy and around the world. The French poet and narrator, from the first translation, by Margherita Sarfatti in 1919, to the last one in 2023 by Luigi Azzariti-Fumaroli, has never stopped being translated by his transalpine cousins, accumulating, as Velez reports, about thirty titles (including reprints) catalogued between the national libraries of Rome and Florence

Simulation Models and Advanced Management Techniques for 5G & Beyond Radio Access Networks
No full textIl 5G sta compiendo una trasformazione significativa del panorama delle reti mobili, introducendo capacità flessibili ed eterogenee che coordinano armoniosamente numerose componenti tecniche dal momento che sono attualmente in fase di sviluppo una grande varietà di servizi avanzati, ognuno dei quali caratterizzato da requisiti diversi. Di conseguenza, appare naturale come il 5G non abbia un'unica interfaccia radio, bensì una famiglia di interfacce radio, tutte opportunamente inserite in un unico framework comune, al fine di rispondere adeguatamente ai diversi casi d'uso.
Tuttavia, la gestione efficace di una così ampia diversità è un obiettivo estremamente ambizioso da raggiungere.
A tal scopo, questo lavoro si pone l'obiettivo di studiare, analizzare e presentare modelli di simulazione, nonché procedure di gestione all’avanguardia delle reti di accesso 5G & Beyond. In particolare, in questa tesi si propone un simulatore system-level ed open source per modellare gli elementi chiave della rete di accesso 5G e supportare quindi l'analisi delle prestazioni di diversi scenari di riferimento. Inoltre, si disamina la NarrowBand IoT, considerata una tecnologia di accesso radio particolarmente promettente per soddisfare i requisiti dello sviluppo 5G & Beyond in ambito Internet of Things (IoT). Infine, si pone un accento sul problema del RAN Slicing sfruttando l'Edge Computing e l'Intelligenza Artificiale, che promettono di trasformare le future reti mobili in infrastrutture che tengano in considerazione i servizi e il canale radio.5th Generation (5G) is providing a significant transformation in the mobile network landscape. It introduces flexible and heterogeneous capabilities to harmoniously blend numerous technical components since a variety of advanced services are being developed, each one entailing different requirements. For this reason, 5G does not have a single air interface, but rather a family of air interfaces to adequately address specific use cases, all plugged into a common framework. Nonetheless, the effective management of such a broad diversity is an extremely ambitious goal to accomplish. To this end, this work pursues the goal of investigating several cutting-edge management techniques and simulation models for 5G & Beyond Radio Access Networks (RANs). Specifically, this thesis presents an open-source system-level tool to model the key elements of the 5G RAN and support the performance analysis of reference scenarios. Moreover, it examines NarrowBand IoT (NB-IoT), which is usually regarded as a promising radio access technology to meet the requirements of the 5G & Beyond development for the Internet of Things (IoT). Finally, it addresses the RAN Slicing problem leveraging Edge Computing and Artificial Intelligence (AI), which promise to turn future mobile networks into service- and radio-aware infrastructures
A cognition-based framework for the development of visualization literacy
No full textData visualizations are prevalent in scientific simulation, medicine, physical therapy, product design, manufacturing, weather predictions, simulations, and engineering. They are also used in information and scientific visualization for WWW exploration, document searching, and education. This pervasiveness makes it important to understand how we comprehend these visualizations, what comprehension difficulties can be expected in diverse populations, and which visual properties increase comprehension difficulty. This will enable us to create training methods that help people gain basic comprehension strategies and analytic skills for visualizations.
The goal of this dissertation is to define an approach that can be used to determine the factors that make a visualization difficult to comprehend by certain individuals. This information is then used to test if training using this information helps individuals develop new and workable strategies for visualization analysis.
In this dissertation we present an approach that is designed as a series of steps designed (1) to determine what cognitive abilities are correlated with comprehension of the visualization, (2) to identify visual properties that make a basic visualization difficult to comprehend and (3) to measure the effect of basic incremental training using these visual properties.Ph.D.Includes bibliographical references (p. 140-146)by Maria C.

Santander: Norte de Santander, near Pamplona, 18 july 2019, <i>collector unknown</i> (holotype: HPUJ).</p> <p> <b>Taxonomic Note:</b> —during the years 2018 and 2019 four closely related species were described from Colombia, all from virtually the same locality. The first was <i>C. yariguii</i> Uribe-Velez & Sauleda (2018a: 1) that, in our opinion, resembles <i>C. naso</i> in the lip shape and is sympatric to it (Govaerts <i>et al.</i> 2022). Then, <i>C. cucutaense</i> Uribe-Velez & Sauleda (2018b: 1), <i>C. bolivarii</i> Uribe-Velez & Sauleda (2018c: 1) and <i>C. pamploanense</i> Salueda (2019: 1) were successively described, and always compared to each other, with the distinguishing features being rather weak, especially between <i>C. yariguii</i> and <i>C. bolivarii</i>. All this led us to treat them as conspecific, under the oldest name, <i>C. yariguii</i>.</p> <p> Another fact that caught our attention was the phenotypic plasticity shown by these taxa, which led us to consider them as hybrids between <i>C. lucis</i> P. Ortiz & G. Arango (1994: 29) and <i>C. naso</i> on the basis of habit, flower color and lip shape, intermediate between these two species, both being sympatric to <i>C. yariguii</i> in Colombia (Govaerts <i>et al.</i> 2022). Moreover, the artificial crossing made by J. Fernández G. produced a plant compatible with the phenotype of <i>C. yariguii</i> and <i>C. bolivarii</i> (see Figure G–H). The other phenotypes should be expressed according to the countless varieties of <i>C. naso</i>.</p> <p> All these nothotaxa present, in fact, similar features, intermediate between <i>C. lucis</i> and <i>C. naso</i>. The flower colour goes from reddish (mostly similar to <i>C. naso</i>) to greenish (mainly as in <i>C. lucis</i>). All of them have a lip presenting some concavity as observed in <i>C. naso</i> (<i>vs.</i> subcordate and convex in <i>C. lucis</i>). The inside of the lip is protruding on both sides by thick projections that form a transverse wall along the lip (as well as in <i>C. naso</i>), however these projections can vary in size and shape due to the existence of two obtuse appendages observed in <i>C. lucis</i>. The lip margin can be either smooth (as in <i>C. lucis</i>) or fimbriate (as in <i>C. naso</i>). The lip apex can be apiculate as in <i>C. naso</i> or more rounded because <i>C. lucis</i> has a lip apex ending into a fleshy structure. When analyzing the images in the descriptions we can note that all of them present antennae first parallel and becoming slightly divergent at apex as in <i>C. naso</i> (<i>vs.</i> antennae strongly divergent in <i>C. lucis</i>) (see Lindley 1843b, Lindley & Paxton 1851, Dunsterville & Garay 1961, Ortiz & Arango 1994, Uribe-Velez & Sauleda 2018a,b,c, Salueda 2019). Since the phenotype is unpredictable in hybrids, especially when the parents present different morphological variations (Rieseberg & Ellstrans 1993), we consider as quite acceptable the variations observed in the four discussed taxa.</p>Published as part of <i>Krahl, Dayse Raiane Passos, Schmal, Philippe, Chiron, Guy, Silva, João Batista Fernandes Da, Krahl, Amauri Herbert & Cantuária, Patrick De Castro, 2023, Catasetum × grasineideae (Orchidaceae: Catasetinae), a new nothospecies from Brazilian Amazon and taxonomic notes for the genus, pp. 89-104 in Phytotaxa 594 (2)</i> on pages 99-100, DOI: 10.11646/phytotaxa.594.2.1, <a href="http://zenodo.org/record/7891982">http://zenodo.org/record/7891982</a>

LYMPHOID DISORDERS ASSOCIATED WITH HHV-8/KSHV INFECTION: FACTS AND CONTENTIONS
No full textFollowing the demonstration in 1994, that Kaposi's sarcoma (KS) was associated with a novel virus (KSHV or HHV-8) belonging to the lymphotropic herpes family, this virus was also found in certain lymphoid neoplasias of immunodeficient (HIV+) and immune competent hosts. The association of HHV-8/KSHV infection is now well established with primary effusion lymphoma (PEL) or body cavity based lymphoma (BCBL) and multicentric Castleman's disease (MCD) of the plasma cell type. A possible pathogenic role of HHV-8/KSHV in other lymphoid tumours including primary central nervous system lymphoma (PCNSL) and multiple myeloma (MM) as well as some atypical lymphoproliferations and sarcoidosis has also been suggested, but this is at present a controversial matter, or not confirmed. Several HHV-8/KSHV genes, including potential oncogenes, genes homologous to various cellular genes and growth factors have been incriminated in the pathogenesis of KS and PEL/BCBL, but a common pathogenic mechanism for the clearly diverse proliferations represented by PEL, MCD and KS is at present not evident
