Age of Information in Practice
CoRR, 2021 While age of Information (AoI) has gained importance as a metric characterizing the fresh-ness of information in information-update systems and time-critical applications, most previous studies on AoI have been theoretical. In this chapter, we compile a set of recent works reporting API measurements in real-life networks and experimental testbeds, and ...

Structure-based insights into evolution of rhodopsins
Communications Biology, 2021 Zabelskii et al. present a structural and functional analysis of the lightdriven proton pump LR (Mac) from the fungus Leptosphaeria maculans. Their findings indicate that the archaeal ancestry of eukaryotic type 1 rhodopsins, and that the archaeal host ...

Measurement in the Age of Information [PDF]
Information, 2022 Information is the resolution of uncertainty and manifests itself as patterns. Although complex, most observable phenomena are not random and instead are associated with deterministic, chaotic systems. The underlying patterns and symmetries expressed from these phenomena determine their information content and compressibility. While some patterns, such

Age Analysis of Status Updating System with Probabilistic Packet Preemption
Entropy, 2022 The age of information (AoI) metric was proposed to measure the freshness of messages obtained at the terminal node of a status updating system. In this paper, the AoI of a discrete time status updating system with probabilistic packet preemption is ...

Optimizing Age Penalty in Time-Varying Networks with Markovian and Error-Prone Channel State
Entropy, 2021 In this paper, we consider a scenario where the base station (BS) collects time-sensitive data from multiple sensors through time-varying and error-prone channels.

Rejuvenation and the Age of Information [PDF]
2019 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW), 2019 Two decades after the seminal paper on software aging and rejuvenation appeared in 1995, a new concept and metric referred to as the age of information (AoI) has been gaining attention from practitioners and the research community. In this vision paper, our aim is to show the similarities and differences between software aging and information aging. In
