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.

Analysis by University of Adelaide researchers has found that claims about sustainability are increasing in agricultural genomics research, but the term is often not well-defined, leading to potential concerns about the impact and credibility of the research.

How do adaptation strategies implemented by dairy farmers to cope with drought affect milk and cheese quality? Researchers from INRAE and VetAgro Sup conducted a trial on an experimental farm in the French Massif Central to assess the effects of decreasing/increasing the amount of grass/corn silage fed to dairy cows on the quality of Cantal-type cheeses. Results published in the Journal of Dairy Science show the importance of maintaining a minimum of fresh grass in dairy cow rations to preserve cheese quality.
