JMIR Publications invites submissions to a new theme issue titled “AI Applications in Biomedical Engineering” in its open access journal JMIR Biomedical Engineering

In a leap forward for miniaturized electronics, researchers have unveiled a groundbreaking method to fabricate high-aspect-ratio 3D microstructures with sub-10 micron resolution—tackling one of the most persistent challenges in radio-frequency (RF) device engineering.

Satellite communication is an indispensable part of sixth generation of mobile communication systems (6G) given its global coverage and long-distance propagation. Energy consumption and channel acquisition are two critical issues in satellite communication systems. On the one hand, with the rapidly increasing energy wastage in wireless systems, green communication technology has attracted extensive attentions and energy efficiency (EE) becomes the key performance indicator in the transmission scheme design of satellite communications. On the other hand, channel state information (CSI) is well required in designing the beamforming, but it is infeasible for gateway (GW) to acquire accurate CSI at the transmitter (CSIT) due to the long-distance delay. Most of the existing work focused on maximizing the total EE (TEE) or minimum EE (MEE) while tradeoff between TEE and MEE has not been investigated in the satellite communication systems. However, it is of both great theoretical and practical significance for satellite systems to investigate the tradeoff between the TEE and MEE so as to balance the total system performance and the fairness in terms of EE.

For the first time passive acoustic monitoring data from all ecological realms have been catalogued on a global scale in a collective effort uniting 350 collaborators working in 57 different countries, coordinated by an INRAE team with French involvement from the Centre National de la Recherche Scientifique (CNRS), the Institut de Recherche pour le Développement (IRD) and the Muséum National d’Histoire Naturelle (MNHN). A summary published in Global Ecology & Biogeography highlights the importance of international collaboration on high-stakes issues such as climate change and the decline in biodiversity.
