Uncovering threats in digital systems: a deep dive into BGP, the blockchain, and Telegram
Full text linkDigital systems have become integral to daily life, driven by the widespread adoption of the Internet, social networks, and blockchain technology. While these advancements enhance access to information, communication, and secure transactions, they also introduce new risks, such as cyber-attacks, misinformation, and financial fraud. This thesis analyzes and proposes solutions to these vulnerabilities, focusing on Internet routing security, cryptocurrency scams, and the impact of conspiracy theories on instant messaging platforms
Similarities among the lithostratigraphic sequences in different parts of the Austrides (Eastern Alps).
No full textThe Basement Complexes in Italy, with special regards to those exposed in the Alps: a review
No full textMost of the sedimentary rocks occurring in Italy are
post-Carboniferous. All what lies below is considered
basement, mostly metamorphic or igneous. Understanding
the pre-Carboniferous evolution depends on the
reconstruction of the sedimentary, metamorphic and
igneous evolution of the basement. In general, the basement
sedimentary protoliths were Lower to Middle Paleozoic
siliciclastic rocks, while the igneous protoliths
belong to an Ordovician cycle. The prevailing metamorphism,
from very-low grade to granulite facies, is
Variscan. It was followed by the formation of large
amounts of granitic melts
The Pressure Character of the Low-Grade Metapelites from Robertson Bay Terrane, northern Victoria Land (Antarctica).
No full textThe geobarometric method based on the b spacing of the white K-micas in metapelites was utilized to determine the pressure character of the metamorphism in Robertson Bay Terrane (RBT) and Bowers Terrane (BT).
Analytical results indicate that no significant differente exists between RBT and BT, and that all b data (240) are close to an average value of 9.027 (3) A.
The conclusion is that both RBT and BT metamorphisms fall in the range of intermediate-pressure (i.e. Barrovian-type) metamorphisms, and can be related to a thermal metamorphic gradient not higher than approximately 15°C/km.
Consequently, plate-tectonic models for northern Victoria Land should take into consideration, as further constraints, the identical metamorphic features of the RRT and BT, and the prevalence of relatively low thermal gradients during the metamorphic climax. This constraint suggests at, in the early Paleozoic, the RBT and the BT both belonged to the same, relatively deep, crustal level, and were both metamorphosed at a considerable depth underneath a thick tectonic cover

Pump and Dumps in the Bitcoin Era: Real Time Detection of Cryptocurrency Market Manipulations
Full text linkIn the last years, cryptocurrencies are increasingly popular. Even people who are not experts have started to invest in these securities and nowadays cryptocurrency exchanges process transactions for over 100 billion US dollars per month. However, many cryptocurrencies have low liquidity and therefore they are highly prone to market manipulation schemes. In this paper, we perform an in-depth analysis of pump and dump schemes organized by communities over the Internet. We observe how these communities are organized and how they carry out the fraud. Then, we report on two case studies related to pump and dump groups. Lastly, we introduce an approach to detect the fraud in real time that outperforms the current state of the art, so to help investors stay out of the market when a pump and dump scheme is in action.Accepted for publication at The 29th International Conference on Computer Communications and Networks (ICCCN 2020
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
