Trust in Edge-based Internet of Things Architectures: State of the Art and Research Challenges
No full textThe Internet of Things (IoT) aims to enable a scenario where smart objects, inserted into information networks, supply smart services for human beings. The introduction of edge computing in IoT can reduce the decision-making latency, save bandwidth resources, and expand the cloud services to be allocated at the network's edge. However, edge-based IoT systems currently face challenges in their decentralized trust management. Trust management is essential to obtain reliable mining and data fusion, improved user privacy and data security, and provisioning of services with context-awareness. In this survey, we first examine the edge-based IoT architectures currently reported in the literature. Then a complete review of trust requirements in edge-based IoT systems is produced. Also, we discuss about blockchain as a solution to solve several trust problems in IoT and analyze in detail the correlation between blockchain and edge computing. Finally, we provide a detailed analysis of performance aspects of trusted edge-based IoT systems and recommend promising research directions
Y box binding protein 1 (YB-1) oncoprotein at the hub of DNA proliferation, damage and cancer progression
No full textThe Y Box binding protein 1 (YB-1) belongs to the highly conserved Cold Shock Domain protein family and is a major component of messenger ribonucleoprotein particles (mRNPs) in various organisms and cells. Cold Shock proteins are multifunctional nucleic acids binding proteins involved in a variety of cellular functions. Biological activities of YB-1 range from the regulation of transcription, splicing and translation, to the orchestration of exosomal RNA content. The role of YB-1 in malignant cell transformation and fate transition is the subject of intensive investigation. Besides, emerging evidence indicates that YB-1 participates in several DNA damage repair pathways as a non-canonical DNA repair factor thus pointing out that the protein can allow cancer cells to evade conventional anticancer therapies and avoid cell death. Here, we will attempt to collect and summarize the current knowledge on this subject and provide the basis for further lines of inquiry
Integrating Blockchain and Edge Computing in Internet of Things: Brief Review and Open Issues
No full textBlockchain has catched significant attention and has been used in several contexts, like Internet of Things (IoT). Anyway, blockchain has a scalability problem that limits its capability to sustain services with several operations. Edge computing is an emerging computing paradigm introduced to distribute services at the network edge, leveraged by the need of meeting low response requirements, mainly for IoT applications. However, edge systems currently face challenges in their decentralized administration and security. The combination of edge computing and blockchain in IoT gives the possibility to solve these challenges. In this paper, we inquire the synergistic combination of blockchain with edge computing in the context of IoT systems. In detail, we first discuss about Edge Computing and its challenges. Then, we introduce the blockchain in Edge-based IoT and analyze several proposal present in the literature. In the end, we draw the open research direction

No full textVariations on the Author
No full text“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
