La forma vivente fra indagine metafisica e ricerca morfologica
2018
Can ontogenesis be read as praxis according to Aristotle’s determination of the notion? In a dialogue with Ronchi’s thinking and starting from the concept life-form, the analysis sketched in this article tries to understand the nature of the ontogenetic processes in their character of energeia atelès

La Grande Guerra racconta sul giornale "L'Ora"
2020
Il saggio propone alcuni momenti ed episodi del primo anno di guerra, attraverso una piccola campionatura di articoli pubblicati sul quotidiano "L’Ora" di Palermo. riguardanti il 1915. Allo scoppio della prima guerra mondiale il quotidiano fondato da Ignazio Florio è al suo quattordicesimo anno di vita ed è sotto la direzione di Francesco Paolo Mulè. Dallo spoglio effettuato emerge che, accanto alla divulgazione dei resoconti ufficiali giunti da Roma, con il quasi quotidiano accompagnamento dei comunicati del Generale Cadorna dal fronte, vengo- no pubblicate corrispondenze di guerra mutuate dal Corriere della sera e del Mattino. Ci si sofferma in particolare su alcuni reportage di Luigi …
A fog-assisted system to defend against Sybils in vehicular crowdsourcing
2022
Technological advancements in vehicular transportation systems have led to the growth of novel paradigms, in which vehicles and infrastructures collaborate to infer high-level knowledge about phenomena of interest. Vehicular Social Network (VSN) is one such paradigm in which vehicular network entities are considered as part of an Online Social Network (OSN), paving the way for new services derived from social context. Although vehicular crowdsourcing has tremendous benefits, its deployment in real systems requires to solve important challenges including defense against Sybil attacks. This paper proposes a novel fog-assisted system that uses SybilDriver to minimize the presence of Sybil enti…
An Efficient and Secure Multidimensional Data Aggregation for Fog-Computing-Based Smart Grid
2021
International audience; The secure multidimensional data aggregation (MDA) has been widely investigated in smart grid for smart cities. However, previous proposals use heavy computation operations either to encrypt or to decrypt the multidimensional data. Moreover, previous fault-tolerant mechanisms lead to an important computation cost, and also a high communication cost when considering a separate identification phase. In this article, we propose an efficient and secure MDA scheme, named ESMA. Unlike existing schemes, the multidimensional data in ESMA are structured and encrypted into a single Paillier ciphertext and thereafter, the data are efficiently decrypted. For privacy preserving, …
Uso de la infografía en la optativa “Alimentación y Dietética” del grado de Medicina
2020
[ES] Como sustitución de la clase magistral, en la sesión dedicada a tratar las características de “dietas occidentales de moda” de la asignatura optativa 34493-Alimentación y Dietética del Grado en Medicina de la Universitat de Valencia, se utilizaron infografías previamente diseñadas por los estudiantes. Con esta iniciativa se pretendía mejorar la participación del alumnado en la asignatura, además de profundizar en la materia, mejorar sus habilidades digitales y de búsqueda y síntesis de información. Esta propuesta fue bien valorada por el estudiantado, que mostró su preferencia por esta forma de trabajar frente a la clase magistral. Además, opinó que la actividad mejoraba su capacidad d…
A data aggregation strategy based on wavelet for the internet of things
2017
The advent of emerging information and communication technologies, such as RFID, small size sensors and sensor networks, has made accessible a huge amount of information that requires sophisticated and efficient search algorithms to support queries on that data. In this paper we focus on the problem of aggregating data collected from these devices to efficiently support queries, inferences or statistics on them. In general, data aggregation techniques are necessary to efficiently collect information in a compact and cost-effective way. Some current solutions try to meet the above criteria, by exploiting different data aggregation techniques, for instance BitVector or Q_Digest. In this manus…
α-parvin is required for epidermal morphogenesis, hair follicle development and basal keratinocyte polarity
2020
Epidermal morphogenesis and hair follicle (HF) development depend on the ability of keratinocytes to adhere to the basement membrane (BM) and migrate along the extracellular matrix. Integrins are cell-matrix receptors that control keratinocyte adhesion and migration, and are recognized as major regulators of epidermal homeostasis. How integrins regulate the behavior of keratinocytes during epidermal morphogenesis remains insufficiently understood. Here, we show that alpha-parvin (alpha-pv), a focal adhesion protein that couples integrins to actin cytoskeleton, is indispensable for epidermal morphogenesis and HF development. Inactivation of the murine alpha-pv gene in basal keratinocytes res…
Timbrel vaults in Sicily: analysis of a little-known construction technique
2016
La ricerca di alternative al legno per la realizzazione di orizzontamenti ha condotto ad approfondimenti e sperimentazioni sulle strutture voltate, con risultati di grande originalità in grado di coniugare economia e leggerezza senza perdere in sicurezza; vengono qui analizzate le volte siciliane costituite da più fogli di mattoni sottili uniti con gesso (volte realine secondo la definizione locale). Già ampiamente documentata nella Spagna tardo-medievale, la tecnica venne introdotta saltuariamente in Sicilia a partire dalla fine del XV secolo, ed assunse un ruolo importante dalla metà del XVIII. Attraverso l’analisi diretta e delle documentazioni relative ai maggiori cantieri e dai prezzia…
Infografiku izmantojums Latvijas Universitātē: pasniedzēju un studentu pieredze
2016
Darba nosaukums ir “Infografiku izmantojums Latvijas Universitātē: pasniedzēju un studentu pieredze”. Mana darba problēmjautājumi: Kādi ir tipiskie principi infografiku vizuālās uztveres pamatā? Kā Latvijas Universitātes pasniedzēji un studenti apkopo uztverto informāciju un kāda ir viņu lietošanas pieredze? Mana pētījuma mērķis ir izpētīt, kādi infografiku veidošanas principi jāievēro, lai veicinātu to sapratni. Mana darba teorētiskajā rāmī tiek iekļauta Geštalta teorija un infografiku vizuālā komunikācija. Metodoloģijā sastāv no kvantitatīvās un kvalitatīvās kontentanalīzes, produkcijas uzdevuma un aptaujas. Rezultāti liecina, ka labākie infografiku piemēri ietver laba turpinājuma un kopī…
