The Metaphysical Reframing of Sustainable and Inclusive Tourism in the Post-pandemic Digital Era: An ELF-mediated Approach

The ongoing research introduced in this paper enquires into the reframing of the concept of ‘sustainable tourism’ prompted by the increasing digitalization of reality following the COVID-19 pandemic emergency which has recorded a growing number of participants in situations of intercultural communication interacting online (within the so-called ‘metaverse’) by using their variations of English as a lingua franca (ELF). Such virtual communicative situations are here assumed to strongly affect,...

Smooth-rough asymmetric PLGA structure made of dip coating membrane and electrospun nanofibrous scaffolds meant to be used for guided tissue regeneration of periodontium

A surgical procedure for the repair of damaged periodontal tissue is Guided Tissue Regeneration (GTR), which involves the use of a barrier membrane to prevent soft tissue ingrowth and create a space for slow regeneration of periodontium and bone. GTR membrane should have pores able to facilitate the diffusion of fluids, oxygen, nutrients, and bioactive substances for cell growth, but also be impermeable to epithelial cells or gingival fibroblasts, which could overpopulate the defect space and...

Multi-stream big data mining for industry 4.0 in machining: Novel application of a Gated Recurrent Unit Network

In Industry 4.0, the availability of signals from multiple sensors stimulates the investigation of novel quality monitoring and prediction methods. This paper tackles the in-line machining process monitoring by exploiting big data in the shape of multi-stream complex signals, eventually containing degradation and tool wear signatures. The proposed novel solution is fed by real-time multichannel data to identify anomalous states in machining applications. We investigate the effectiveness of a ...
