Cats, flowers and Harry Hill’s car on fire – RA Summer Exhibition review
Royal Academy, LondonBowie karaoke in a cupboard, a gross David Gamble self-portrait and Harriet Porter’s serene silver pot are a welcome distraction from the tidal wave of landscapes and famous artists’ hand-me-downs for saleThis year’s RA Summer Exhibition is less awful than usual. It’s still full of some of the worst art you’ve ever seen – way too many Michael Craig-Martins and Bob and Roberta Smiths – but its awfulness is definitely a bit less awful. This relative less-awfulness is...

RA-LWLM: Retrieval-Augmented In-Context Localization with Wireless Foundation Models
arXiv:2606.01899v1 Announce Type: cross Abstract: Wireless localization is a fundamental capability of sixth-generation (6G) networks. Conventional model-based methods require accurate modeling of the propagation environment and degrade in complex multipath and non-line-of-sight scenarios, while learning-based methods couple model parameters tightly to the training scene, requiring costly retraining whenever the base station (BS) configuration or propagation environment changes. In this...
Rotatable Antenna-Enhanced Cell-Free Communication
arXiv:2512.04742v3 Announce Type: replace Abstract: Rotatable antenna (RA) is a promising technology that can exploit new spatial degrees-of-freedom (DoFs) by flexibly adjusting the three-dimensional (3D) boresight direction of antennas. In this letter, we investigate an RA-enhanced cell-free system for downlink transmission, where multiple RA-equipped access points (APs) cooperatively serve multiple single-antenna users over the same time-frequency resource. Specifically, we aim to maximize...

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...
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-Enabled Mobile Edge Computing
Announce Type: replace Abstract: In the evolving landscape of mobile edge computing (MEC), enhancing communication reliability and computation efficiency to support increasingly stringent low-latency services remains a fundamental challenge. Rotatable antenna (RA) is a promising technology that introduces new spatial degrees of freedom (DoFs) to tackle this challenge. In this letter, we investigate an RA-enabled MEC system where antenna boresight directions can be independently adjusted to...
Rotatable Antenna-Enabled Satellite Communication: Joint Design of Boresight Alignment and Beam Tracking
new Abstract: Low Earth orbit (LEO) satellite links experience rapid angular variation due to high orbital velocities, which causes severe beam misalignment and array gain degradation under conventional fixed-antenna architectures. In this letter, we propose a rotatable antenna (RA)-enabled LEO communication framework, where RA arrays are deployed at both the satellite and the ground node (GN) to exploit antenna boresight reconfiguration as an additional spatial degree-of-freedom (DoF) for...
The P2X7 receptor is an intermediate in the retinoic acid-signaling pathway that induces neuronal remodeling in retinitis pigmentosa
Photoreceptor degeneration drives electrophysiological remodeling in downstream retinal neurons, including hyperactive firing of retinal ganglion cells (RGCs) that degrades residual vision. Although Retinoic Acid (RA) and its receptor (RAR) are known to upregulate ion channel genes associated with RGC hyperactivity, these genes lack canonical RAR binding sites required for direct transcriptional regulation. Here, we identify P2X7 receptor (P2X7R) as a key intermediary in RA-induced...
