DBMC-aNOMAly: Asynchronous NOMA with Pilot-Symbol Optimization Protocol for Diffusion-Based Molecular Communication Networks

arXiv:2512.07317v2 Announce Type: replace Abstract: Multiple access (MA) schemes can enable cooperation between multiple nodes in future diffusion-based molecular communication (DBMC) networks. Non-orthogonal MA for DBMC networks (DBMC-NOMA) is a promising option for efficient simultaneous MA using a single molecule type.

Energy Efficiency Optimization for Rotatable Antenna-Enabled Uplink NOMA Systems

arXiv:2606.05600v1 Announce Type: new Abstract: This paper investigates a rotatable antenna (RA)-enabled uplink non-orthogonal multiple access (NOMA) system, where a base station equipped with multiple independently RAs serves both ground and aerial users. Specifically, we formulate an energy efficiency (EE) maximization problem by jointly optimizing receive beamforming, user power allocation, and RA rotation. To make the problem tractable, a new block coordinate descent-based algorithm is...

Rotatable Antenna Meets Multiple Access: NOMA or OMA?

arXiv:2606.03035v1 Announce Type: new Abstract: Rotatable antenna (RA) technology has emerged as a promising solution to enhance spectrum efficiency by exploiting additional spatial degrees of freedom (DoFs) in multiple access networks. However, the relative performance superiority among different multiple access schemes remains largely unclear due to the unique capability of RA in reconfiguring the directional gain pattern. In this letter, we conduct a theoretical comparison between...

Bar Shrimp, Manchester M1: ‘This is meaningful, highly adept cooking’ – restaurant review | Grace Dent on restaurants

One of the best seats in Manchester, if not the entire northI’m perched on a tall stool at a new Manchester bar, perusing a menu of fishy things and various aquatically adjacent items: Lindisfarne oysters, devilled eggs with brown crab and trout roe, hand-dived razor clams and scallop tartare with elderflower dressing. Bar Shrimp sits on New York Street, which feels weirdly fitting, because this place is much more “quietly sceney” New York than anything remotely “aren’t we edgy?” London....

US aerial refuelling plane crashes in western Iraq

US officials have said a KC-135 refuelling plane that went down in western Iraq was not the result of hostile or friendly fire. They said it had involved a second refuelling aircraft that landed safely. Six crew members were reported to be on the plane that crashed.
