Design and Realization of an UHF Frequency Reconfigurable Antenna for Hybrid Connectivity LPWAN and LEO Satellite Networks.

UHF satellite communication for Internet of Things (IoT) technology is rapidly emerging in monitoring applications as it offers the possibility of lower-costs and global coverage. At the present time, Low Power Wide Area Network (LPWAN) solutions offer low power consumption, but still suffer from white zones. In this paper, the authors propose an UHF frequency reconfigurable Antenna for hybrid connectivity LoRaWAN (at 868 MHz) and UHF satellite communication (Tx at 401 MHz and Rx at 466 MHz) with the Low Earth Orbit (LEO) Kineis constellation.

A Real-Time Continuous Cardiac Arrhythmias Detection System: RECAD.

Cardiac arrhythmia is a class of serious heart diseases that threatens many people. Current arrhythmias diagnostic techniques seem to be partially efficient due to the application limitations either in time or in space. The paper presents a real-time continuous arrhythmias detection system (RECAD) platform based on the wireless sensor network technology.

Histomorphometric comparison of three bioabsorbable GTR barrier membranes in the canine model.

Guided tissue regeneration (GTR) using bioabsorbable barrier membranes has shown promising and somewhat predictable clinical results. However, limited information is available on the stages of histologic healing when these types of barriers are used. Therefore, the aim of this study was to compare three currently available bioabsorbable GTR barriers (type 1 collagen, polylactide/polyglycolide copolymer, and citric acid copolymer) for the treatment of surgically created periodontal dehiscences in dogs.

Remote continuous cardiac arrhythmias detection and monitoring.

The current techniques used to diagnose cardiac arrhythmias such as Holter, Rtest and telemetry systems are partially efficient because they are limited either in time or in space. In this paper, a platform dedicated to the real-time remote continuous cardiac arrhythmias detection and monitoring is proposed. Such a platform allows to improve the accuracy and the efficiency of the diagnostic of ventricular tachycardia among the high-risk patients and enables the implantation of ICD to prevent sudden death.

[Tartrate-resistant acid phosphatases (TRAP) and cytology of pseudosynovial membranes].

Pseudo-synovial membranes are found at the interface between bone and aseptically lost prostheses. They are supposed to be due to the release of material debris at the interface with bone. They are mostly composed of macrophages and giant cells, and some fibrocytes in the deep layer of the membrane.
