Integrating 6LoWPAN Security with RPL Using The Chained Secure Mode Framework [PDF]
arXiv, 2021 The IPv6 over Low-powered Wireless Personal Area Network (6LoWPAN) protocol was introduced to allow the transmission of Internet Protocol version 6 (IPv6) packets using the smaller-size frames of the IEEE 802.15.4 standard, which is used in many Internet of Things (IoT) networks.

Analysis of the LTE Access Reservation Protocol for Real-Time Traffic [PDF]
, 2013 LTE is increasingly seen as a system for serving real-time Machine-to-Machine (M2M) communication needs. The asynchronous M2M user access in LTE is obtained through a two-phase access reservation protocol (contention and data phase). Existing analysis related to these protocols is based on the following assumptions: (1) there are sufficient resources ...

Optical scheme for cryptographic commitments with physical unclonable keys [PDF]
Optics Express Vol. 27, 29367-29379 (2019), 2019 We investigate the possibility of using multiple-scattering optical media, as resources of randomness in cryptographic tasks pertaining to commitments and auctions. The proposed commitment protocol exploits standard wavefront-shaping and heterodyne-detection techniques, and can be implemented with current technology.

An Adaptive Hybrid Channel Reservation Medium Access Control Protocol for Differentiated QoS [PDF]
arXiv, 2023 In a densely deployed distributed wireless network, there may be various types of traffic with differentiated Quality of Service (QoS) requirements. However, when the network is heavily loaded, the collision increases significantly, making it difficult to guarantee the QoS of traffic.

Accessible ecophysiological tools for seabird conservation
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1983-2002, December 2022., 2022 Abstract Seabirds are the most endangered avian taxa on Earth, with over a third of species globally threatened. To help slow their decline, conservation physiology seeks to determine how seabird responses to climatic and anthropogenic threats influence demographic processes, but it is not widely utilized in monitoring.

Machine stability and dosimetry for ultra‐high dose rate FLASH radiotherapy human clinical protocol
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The FLASH effect, induced by ultra‐high dose rate (UHDR) irradiations, offers the potential to spare normal tissue while effectively treating tumors. It is important to achieve precise and accurate dose delivery and to establish reliable detector systems, particularly for clinical trials needed to help the clinical transfer of FLASH‐
