The Information Theory of Aging

Nature Aging, 2023
Information storage and retrieval is essential for all life. In biology, information is primarily stored in two distinct ways: the genome, comprising nucleic acids, acts as a foundational blueprint and the epigenome, consisting of chemical modifications to DNA and histone proteins, regulates gene expression patterns and endows cells with specific ...

Status update control based on reinforcement learning in energy harvesting sensor networks

Frontiers in Communications and Networks, 2022
With the development of the Internet of Things, more and more sensors are deployed to monitor the environmental status. To reduce deployment costs, a large number of sensors need to be deployed without a stable grid power supply.

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 ...

HAP-Enabled Communications in Rural Areas: When Diverse Services Meet Inadequate Communication Infrastructures

IEEE Open Journal of the Communications Society, 2023
The high altitude platform (HAP) network has been regarded as a cost-efficient solution for providing network access to rural or remote areas. Apart from network connectivity, rural areas are predicted to have demands for diverse real-time intelligent ...

Age of Information in Practice

, 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 ...
