Radio Map-Based Spectrum Sharing for Joint Communication and Sensing

open access: yesIEEE Open Journal of the Communications Society
The sixth-generation (6G) network is expected to provide both communication and sensing (C&S) services. However, spectrum scarcity poses a major challenge to the harmonious coexistence of C&S systems.

Indoor Localization Method Based on Sequential Motion Tracking Using Topological Path Map

open access: yesIEEE Access, 2019
This paper proposes a novel indoor localization method based on sequential motion tracking (SMT) using a topological path map that can improve the shortcomings of traditional methods using range-only measurement sensors.

Radio Map Interpolation Using Graph Signal Processing [PDF]

open access: yesIEEE Communications Letters, 2018
Interpolating a radio map is a problem of great relevance in many scenarios such as network planning, network optimization, and localization. In this letter, such a problem is tackled by leveraging recent results from the emerging field of signal processing on graphs. A technique for interpolating graph structured data is adapted to the problem at hand

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
