Il contributo propone un’analisi del racconto della nobile menzogna che Socrate, in dialogo con Glaucone, narra nel III libro della Repubblica al termine della riflessione sul falso nei racconti, sulla forma espressiva e sulle norme per la produzione letteraria ammessa nella città ideale. Dopo aver stabilito la possibilità di produrre un racconto falso che tende al vero, sui fatti del passato, Socrate offre il γενναῖον ψεῦδος segnalando il rapporto con la poesia della tradizione, in termini di continuità e di distanza. Nella nobile menzogna Platone rielabora infatti sia il mito di Cadmo sugli uomini nati dalla terra, sia il mito delle cinque stirpi che Esiodo sviluppa negli Erga. Considerando le differenze e le innovazioni e osservando brevemente l’esegesi antica, sarà possibile considerare la nobile menzogna come la riscrittura della memoria letteraria della tradizione greca, come dunque uno ψεῦδος utile e ammesso perché in vista del fine etico della παίδεια.

While the Homeric epics primarily focus on the Greek and Trojan heroes battling outside Troy’s walls, they also hark back to earlier heroic eras. Among past heroes, Herakles is the most frequently mentioned. The Iliad often references Herakles’ exploits, but the Odyssey only briefly evokes him in a few verses. The most extended mention occurs in the nekyia (Od. 11. 601-627), a passage presenting oddities that have been widely debated and interpreted. This paper considers the passage focusing on the diffuse confusion of temporal levels that it presents in the light of frameworks related to mind and consciousness. Inspired by the seminal works of Snell and Dodds and the controversial yet increasingly validated theories of Jaynes, supported by neuroscientific insights and Damasio’s endorsement, it explores recent research on consciousness in perceiving and describing time. It investigates whether this Homeric passage may reflect a transitional phase from one stage of development of the human cognitive system to a subsequent one characterised by different functional traits.

In this paper we develop a classification of real functions based on growth rates of repeated iteration. We show how functions are naturally distinguishable when considering inverses of repeated iterations. For example, $n+2\to 2n\to 2^n\to 2^{\cdot^{\cdot^2}}$ ($n$-times) etc. and their inverse functions $x-2, x/2, \log x/\log 2,$ etc. Based on this idea and some regularity conditions we define classes of functions, with $x+2$, $2x$, $2^x$ in the first three classes. We prove various properties of these classes which reveal their nature, including a `uniqueness' property. We exhibit examples of functions lying between consecutive classes and indicate how this implies these gaps are very `large'. Indeed, we suspect the existence of a continuum of such classes.

Memristor has been identified as the fourth fundamental circuit element by Dr. Leon Chua in 1971 and since then it has gathered a lot of interest because of its non-volatility and are considered as a viable solution to the beyond CMOS era computation. Recently, memristor have been used to perform basic logic operations like AND, OR, NAND, NOR, XOR etc. and are also used in applications like Dot Product Engine, Convolution Neural Networks etc. This paper presents a new behavioural model of memristor then using it to build a 32-bit ripple carry adder. The paper later compares the area, power and time delay of the 32 bit Ripple Carry Adder using memristor with the 45nm CMOS technology and highlights its advantages and pitfalls.

In this work, we propose an end-to-end Thrust Microstepping and Decoupled Control (TMDC) of quadrotors. TMDC focuses on precise off-centered aerial grasping of payloads dynamically, which are attached rigidly to the UAV body via a gripper contrary to the swinging payload. The dynamic payload grasping quickly changes UAV's mass, inertia etc, causing instability while performing a grasping operation in-air. We identify that to handle unknown payload grasping, the role of thrust controller is crucial. Hence, we focus on thrust control without involving system parameters such as mass etc. TMDC is based on our novel Thrust Microstepping via Acceleration Feedback (TMAF) thrust controller and Decoupled Motion Control (DMC). TMAF precisely estimates the desired thrust even at smaller loop rates while DMC decouples the horizontal and vertical motion to counteract disturbances in the case of dynamic payloads. We prove the controller's efficacy via exhaustive experiments in practically interesting and adverse real-world cases, such as fully onboard state estimation without any positioning sensor, narrow and indoor flying workspaces with intense wind turbulence, heavy payloads, non-uniform loop rates, etc. Our TMDC outperforms recent direct acceleration feedback thrust controller (DA) and geometric tracking control (GT) in flying stably for aerial grasping and achieves RMSE below 0.04m in contrast to 0.15m of DA and 0.16m of GT.

Many of Levi’s speculative stories narrate dystopian scenarios in which individuals express anxiety about the creeping power of technology which is reifying and automating their posthuman bodies, affecting their physical and psychological freedoms. This article develops previous scholarship with a specific focus on the gendered dimension of Levi’s writing. I show how he critiques the problematic ways in which technologisation impacts specifically on women’s bodies. With a view to tracing the contemporary echoes of Levi’s work, I place his stories in dialogue with Nicoletta Vallorani’s recent, more explicitly feminist novels. I argue that Vallorani’s writing echoes and develops many of Levi’s concerns about how technology can be employed to constrain our bodies and consciousness, and the explicitly gendered dimensions of this oppression. A critical reading of these texts alongside one another reveals striking resonances and confirms how Levi’s intuitions regarding the importance of critiquing unfettered technologised embodiment remain urgently relevant today.

In cybersecurity courses, it is quite challenging to do hands-on activities that involve many components of the Internet, such as bringing down the Internet, attacking a blockchain, etc. To solve this problem, we have developed an open-source Internet Emulator, which is a Python library, consisting of the classes for each essential element of the Internet, including autonomous system, network, host, router, BGP router, Internet exchange, etc. It also includes the classes for a variety of services, including Web server, DNS, Botnet, Darknet, Blockchain, and more are being developed. Using these classes, users can construct a mini-Internet to emulate the real-world Internet. Although it is small, it has all the essential elements of the real Internet. The construction is compiled into Docker container files, and the emulation is executed by Docker on a single machine, or on multiple cloud machines. With this Internet Emulator, we can develop a variety of hands-on activities for cybersecurity courses, including BGP prefix hijacking, attacks on smart contract, using Darknet to achieve anonymity, launching Botnet and ransomware attacks, etc. While the emulator was initially developed for cybersecurity courses, it can also be used for network courses, for students to learn how the Internet technologies work, such as routing, BGP, IP Anycast, and DNS. Many other interesting network technologies can also be deployed on the emulator, such as content delivery network and software-defined network.

An increasing body of work has recognized the importance of exploiting machine learning (ML) advancements to address the need for efficient automation in extracting access control attributes, policy mining, policy verification, access decisions, etc. In this work, we survey and summarize various ML approaches to solve different access control problems. We propose a novel taxonomy of the ML model's application in the access control domain. We highlight current limitations and open challenges such as lack of public real-world datasets, administration of ML-based access control systems, understanding a black-box ML model's decision, etc., and enumerate future research directions.

Nella letteratura postcoloniale appaiono spesso figure di donne afasiche o mute. Si tratta di personaggi che non parlano, per scelta o per inibizione: donne che non hanno o hanno perduto l’uso della parola; ragazze dai tratti quasi autistici; inquietanti, intriganti figure femminili che rifiutano di esprimersi attraverso il linguaggio, donne tutte che vivono il rapporto con il mondo esterno come violenza. Proprio reagendo a questa situazione, i personaggi femminili dei più recenti romanzi postcoloniali iniziano a parlare: prima per lallazioni, come i bambini che sperimentano un nuovo linguaggio, poi mettendo assieme parole, in fine intere frasi. E finalmente arrivano a raccontarsi, a raccontare, la loro storia, rendendosi conto che ogni persona è la propria storia, e che la violenza più subdola, perpetrata sulle donne, è quella di metterle a tacere.

Products in an ecommerce catalog contain information-rich fields like description and bullets that can be useful to extract entities (attributes) using NER based systems. However, these fields are often verbose and contain lot of information that is not relevant from a search perspective. Treating each sentence within these fields equally can lead to poor full text match and introduce problems in extracting attributes to develop ontologies, semantic search etc. To address this issue, we describe two methods based on extractive summarization with reinforcement learning by leveraging information in product titles and search click through logs to rank sentences from bullets, description, etc. Finally, we compare the accuracy of these two models.

Twinkling Artifact is a valuable tool in detecting dense objects such as kidney stones, calculi etc., especially when there is no acoustic shadowing and presence of hyperechogenic tissues obstructs visualization. This phenomenon is not completely understood. Different scientific groups have contradictory findings concerning its properties: some of them observed a decrease in Twinkling intensity at elevated pulse repetition frequencies (PRF), while others found Twinkling to be independent from PRF, etc. In this paper we hypothesize that this kind of contradictions can be partially resolved on an assumption that there are two types of Twinkling. The 1st type presumably is produced by random-phased reflections from microcavitation and can be registered even at PRF high enough to suppress blood flow. The 2nd is originated from elastic vibrations as the object under investigation swings like a pendulum in the field of ultrasound. These vibrations can be associated with an external source such as a muscles contraction, etc. or the acoustic radiation force from signals emitted by the transducer. The 2nd type of Twinkling disappears at high PRF and can be regularly observed in silicone and polyurethane phantoms where the occurrence of cavitation microbubbles is highly unlikely. Key Words: Ultrasound Imaging, Twinkling Artifact, Stone Detection, Doppler Effect, Color Frame Mapping, Acoustic Radiation Force, Elastic Vibration, Ultrasound Phantom, Cavitation, Microbubbles.

Nonostante sia rimasto nell’ombra a lungo,La Regenta(1884-85) di Leopoldo Alas ‘Clarín’ è oggi considerato uno dei romanzi capolavoro della letteratura spagnola della fine dell’Ottocento.  Il processo del suo riconoscimento come classico moderno, sebbene ancora ‘relativo’, si è avviato a partire dagli anni cinquanta del ventesimo secolo e non si è più arrestato. La vitalità de La Regentain epoca contemporanea è attestata anche dalle tante riscritture che ha originato. L’articolo ne traccia una panoramica per poi soffermarsi sull’analisi dell’adattamento a graphic novel(1999-2001) di Isaac del Rivero e sulla presenza nel web di siti dedicati all’autore e all’opera. Although it dwelt for a long time in the shadows, today La Regenta(1884-85) by Leopoldo Alas ‘Clarín’ is considered a masterpiece among late-nineteenth-century Spanish novels. Its recognition as a modern classic, though still “limited,” began in the Fifties of the twentieth century and has not stopped since. La Regenta’s significance for the contemporary period is demonstrated by its many rewritings. This paper provides a review of these before analyzing in greater detail its adaptation as a graphic novel (1999-2001) by Isaac del Rivero, as well as the presence on the internet of websites devoted to the novel and its author.

Im Zuge der Modernisierung haben die religiösen Erzählungen ihre Einheit stiftende Kraft verloren. An ihre Stelle ist die menschliche Vernunft getreten und mit ihr die Logik eines rationalen, ganz auf Fortschritt ausgerichtetes Handelns, während Beziehungserfahrungen und mit ihr der unverzichtbare Wunsch nach Resonanz immer stärker in den Hintergrund treten. Menschen lassen sich auf Dauer aber nicht allein mit effizienzorientierten Rückmeldungen abspeisen. Sie warten auf Anerkennung, die von außen kommt; sie warten auf Resonanz. Hartmut Rosa hat die Vorstellung von einem Verstummen der Welt, in der der verzweifelte Ruf nach dem Anderen keine Antwort mehr findet, nicht umsonst als die tiefste Angst bezeichnet, der  die Menschen heute umtreibt. Die Autorin beschreibt vor diesem Hintergrund die Erfahrung von Resonanz als menschliches Grundbedürfnis und zeigt als erstes an Beispielen aus der Literatur, wie diese sich dort in  außergewöhnlichen Naturerlebnissen, in der Selbstentgrenzung von Liebesbeziehungen und in der präreflexiven Erfahrung Gottes, die keiner weiteren Begründung mehr bedarf, erfahrbar wird. Anschließend wendet sie sich Resonanzerfahrungen im Bereich der Psychoanalyse zu. Im letzten Abschnitt ihrer Arbeit befasst sie sich mit Resonanzerfahrungen in der pluralistischen Gesellschaft, in der es unterschiedliche Sinndeutungen gibt, die gleichermaßen legitim sind und nach Anerkennung verlangen.

Il saggio si propone di riprendere la questione della narratività in relazione alle prime due opere finzionali di Giorgio Manganelli: Hilarotragoedia e Nuovo commento. Il primo paragrafo discute la classica definizione di Manganelli come scrittore antinarrativo, ripercorrendo alcune delle principali prese di posizione dell’autore contro il genere romanzesco e più in generale intorno al concetto di narrazione. Il secondo paragrafo legge alcuni passi dei due libri di Manganelli sulla scorta della teoria delle forme temporali proposta da Harald Weinrich in Tempus. Besprochene und erzählte Welt. L’ultimo paragrafo mette a fuoco alcune conseguenze dell’applicazione della teoria di Weinrich a questo contesto, concentrandosi in particolare sull’uso dinamico che Manganelli fa della figura dell’evidentia, utilizzata come una strategia nascosta di fabulazione narrativa. The main purpose of this essay is to reconsider the problematic issue of narrativity in Giorgio Manganelli’s earliest fictional works: Hilarotragoediaand Nuovo commento. The first paragraph debates the classic definition of Manganelli as an antinarrative writer and reexamines the main positions of the author against the novel and around the concept of narration in general. The second paragraph provides an interpretation of Manganelli’s fictional treatises through Harald Weinrich’s theory as outlined in Tempus. Besprochene und erzählte Welt. The last paragraph tries to draw some conclusions from the application of Weinrich’s theory to this context and focuses on Manganelli’s dynamic use of ecphrasis as a hidden strategy of narration.

Se propone una reflexión sobre la escritura del escritor italiano Carlo Emilio Gadda a través de la forma en que el autor incorpora a sus textos las expresiones del dialecto milanés. Asimismo, se delinea el camino que hemos elegido para llevar a cabo una posible traducción al castellano de esos nudos dialectales. Concretamente, se hará referencia al relato San Giorgio in casa Brocchi y al último de los Disegni milanesi que componen L’Adalgisa y al que la obra debe su título.
