Abstract

Artificial Intelligence of things (AIoT) is the combination of Artificial Intelligence (AI) technologies and the Internet of Things (IoT) infrastructure. AI deals with the devices' learning process to acquire knowledge from data and experience, while IoT concerns devices interacting with each other using the Internet. AIoT has been proven to be a very effective paradigm for several existing applications as well as for new areas, especially in the field of satellite communication systems with mega-constellations. When AIoT meets space communications efficiently, we have interesting uses of AI for Satellite IoT (SIoT). In fact, the number of space debris is continuously increasing as well as the risk of space collisions, and this poses a significant threat to the sustainability and safety of space operations that must be carefully and efficiently addressed to avoid critical damage to the SIoT networks. This paper aims to provide a systematic survey of the state of the art, challenges, and perspectives on the use of deep learning methods for space situational awareness (SSA) object detection and classification. The contributions of this paper can be summarized as follows: (i) we outline using AI algorithms, and in particular, deep learning (DL) methods, the possibility of identifying the nature/type of spatial objects by processing signals from radars; (ii) we present a comprehensive taxonomy of DL-based methods applied to SSA object detection and classification, as well as their characteristics, and implementation issues.

Abstract

Monitoring and conservation of natural resources such as trees have become necessary as the impact of new diseases attacking the integrity of trees has created major concerns for environmentalists and communities in recent years. \ud Within this context, tree roots are one of the plants' most important and vulnerable organs as well as one of the most challenging ones to inspect. Tree roots naturally are developed under the ground, hence difficult to be seen and access. To that effect, the non-destructive testing (NDT) methods have become one of the preferred methods of tree roots assessment and monitoring as opposed to other conventional and destructive techniques. The applications of the ground penetrating radar (GPR) have proven to be an accurate approach and methodology for the investigation and mapping of tree roots. However, a major challenge for GPR detection of tree roots architecture and pattern accurately is the soil inhomogeneity, including the presence of various natural and artificial features within the soil.\ud This study aims to mitigate the uncertainty in root detection by proposing a deep learning method based on the analysis of GPR spectrograms (i.e., a graphic representation of a signal's frequency spectrum with respect to time). In this study, the GPR signal is first processed in both the time and frequency domains to filter the existing noise-related information and hence, to produce spectrograms. Subsequently, an image-based deep learning framework is implemented, and the effectiveness in detecting tree roots is analysed in comparison with conventional feature-based machine learning classifiers. The preliminary results of this research demonstrate the potential of the proposed approach and pave the way for the implementation of new methodologies in assessing tree root systems.

Abstract

Hepatocellular carcinoma (HCC) is a major healthcare problem worldwide, representing one of the leading causes of cancer mortality. Since there are currently no predictive biomarkers for early stage diagnosis, HCC is detected only in advanced stages and most patients die within one year, as radical tumour resection is generally performed late during the disease. The development of alternative therapeutic approaches to HCC remains one of the most challenging areas of cancer. This review focuses on the relevance of cAMP signalling in the development of hepatocellular carcinoma and identifies the modulation of this second messenger as a new strategy for the control of tumour growth. In addition, because the cAMP pathway is controlled by phosphodiesterases (PDEs), targeting these enzymes using PDE inhibitors is becoming an attractive and promising tool for the control of HCC. Among them, based on current preclinical and clinical findings, PDE4-specific inhibitors remarkably demonstrate therapeutic potential in the management of cancer outcomes, especially as adjuvants to standard therapies. However, more preclinical studies are warranted to ascertain their efficacy during the different stages of hepatocyte transformation and in the treatment of established HCC. [ABSTRACT FROM AUTHOR]

Abstract

Alberto Petrucciani, al quale amici, allievi e colleghi dedicano questo libro, è stato dapprima bibliotecario nell'Università di Genova e nelle biblioteche pubbliche statali, poi professore ordinario presso le Università di Bari (1986-1993), Pisa (1993-2009), e oggi presso la Facoltà di lettere e filosofia della Sapienza Università di Roma, dove insegna Teorie e tecniche della catalogazione e Storia delle biblioteche. Ha ricoperto e tuttora ricopre prestigiosi incarichi culturali e istituzionali. Animatore dell'Associazione italiana biblioteche, è stato Vicepresidente dal 1991 al 1993 e dal 1997 al 2003, ha diretto il «Bollettino AIB» dal 1992 al 2000, e dal 1991 è responsabile scientifico delle edizioni dell'Associazione. Dal 2012 è Coordinatore del Dottorato di ricerca in Scienze documentarie, linguistiche e letterarie (con sede presso la Sapienza) e direttore della rivista «Nuovi annali della Scuola speciale per archivisti e bibliotecari». Presidente dal 2016 del Comitato tecnico scientifico per le biblioteche e gli istituti culturali del MiBACT, è anche membro del Consiglio superiore per i beni culturali e paesaggistici, e dal 2013 al 2018 è stato presidente della Società italiana di scienze bibliografiche e biblioteconomiche (SISBB). Dal 2021 è membro del Comitato di indirizzo della Scuola superiore di studi avanzati della Sapienza Università di Roma. Rigoroso, autorevole e brillante studioso, è autore di numerosi volumi e articoli scientifici che spaziano dalla catalogazione alla biblioteconomia, dal libro antico alla storia delle biblioteche e dei bibliotecari, sino ai più recenti contributi relativi ai lettori in biblioteca. Tra le numerose pubblicazioni ricordiamo: Funzione e struttura del catalogo per autore (1984), Gli incunaboli della Biblioteca Durazzo (1988), Guida alle fonti di informazione della biblioteconomia (1996, con Riccardo Ridi), BIB: Bibliografia italiana delle biblioteche, del libro e dell'informazione (2005, con Vittorio Ponzani), Libri e libertà: biblioteche e bibliotecari nell'Italia contemporanea (2012), Le biblioteche di Luigi Crocetti: saggi, recensioni, paperoles, 1963-2007 (2014, con Laura Desideri), What happened in the library? Readers and libraries from historical investigations to current issues: international research seminar = Cosa è successo in biblioteca? Lettori e biblioteche tra indagine storica e problemi attuali: seminario internazionale di ricerca (Roma 27-28 settembre 2018) (2020, con Enrico Pio Ardolino e Vittorio Ponzani), Manuale di catalogazione: principi, casi e problemi (2021, con Simona Turbanti). Organizzati in cinque sezioni tematiche disegnate sul percorso di ricerca di Petrucciani, gli interventi pubblicati in questo volume vogliono fornire un affettuoso omaggio a uno studioso che – con lo sguardo rivolto alle biblioteche – ha offerto stimoli e contributi fondamentali per tutti, sempre all'insegna del pensiero critico e della solidarietà nella ricerca.
