FlexLink: Decoupling Control and Data Beams for Next-Generation Wideband Networks
arXiv:2606.01454v1 Announce Type: cross Abstract: The next generation of 6G networks aims to utilize ultra-wideband spectrum and massive antenna arrays to serve multiple users with both control and data channels at low latency and high efficiency. However, phased arrays at mmWave and mid-bands are fundamentally constrained to a single beam or suffer sharp beamforming loss when split across directions, limiting simultaneous control-data support. In FlexLink, we introduce and prototype a novel...
Texture-preserving implicit neural representation for Cone beam CT truncated reconstruction
arXiv:2606.06039v1 Announce Type: new Abstract: Cone-beam computed tomography (CBCT) frequently suffers from data truncation, which introduces severe artifacts and limits the effective field of view (FOV). Existing deep learning methods for truncated cone-beam computed tomography (CBCT) reconstruction suffer from serious limitations, including a strict reliance on supervised ground truth and a failure to account for continuous 3D spatial truncation variations. To address these challenges, we...
Beam Instrumentation
Physics > Accelerator Physics [Submitted on 2 Jun 2026] Title:Beam Instrumentation View PDFAbstract:Beam instrumentation is known as the 'eyes and ears of a particle accelerator'. It provides the data required for the most basic operating functions such as beam steering and intensity measurement, but also for diagnosing problems and optimising performance.
The First Nozzle-Mounted Compton Camera Prompt Gamma Imaging System for In Vivo Proton Therapy Dose Verification
arXiv:2606.03978v1 Announce Type: new Abstract: This study presents the first clinical integration and experimental demonstration of a nozzle-mounted Compton camera prompt gamma imaging (PGI) system for in vivo proton range verification. Four position-sensitive solid-state Compton camera modules, each containing four cadmium zinc telluride (CdZnTe) detector crystals, were integrated into a modified range shifter mounted directly on the treatment nozzle of a clinical proton therapy gantry....
FRED: A Multi-Modal Autonomous Driving Dataset for Flooded Road Environments
arXiv:2605.22018v2 Announce Type: replace Abstract: The Flooded Road Environments Dataset (FRED) is, to our knowledge, the first multi-modal autonomous driving dataset specifically targeting the collection of data from scenarios involving water hazards on the road. The dataset contains images from a 2.3 MP FLIR Blackfly USB3 camera, 64-beam 360 degree point clouds from an Ouster OS1-64 LiDAR, and data from an iXblue ATLANS-C IMU corrected by a Geoflex RTK GNSS, from five separate locations...
Physicists achieve 'perfect randomness' for the first time ever
Physicists achieve 'perfect randomness' for the first time ever Physicists used quantum bits to achieve 'perfect randomness' in a world-first experiment. The results of their research could strengthen cryptography and other security systems. Researchers at ETH Zurich have demonstrated a means of generating "perfect randomness" by using entangled superconducting qubits.
There's still no point in gigabit broadband
Six years ago, I nearly got my ISP to upgrade our fibre connection to 1Gbps. As I said at the time: This is a curmudgeonly post which is going to look ridiculously outdated in a few years. Well, it's a few years later and Virgin Media have just given me their Gig1 package for £30 per month.
Efficient and accurate neural-field reconstruction using resistive memory
Abstract Applications such as medical imaging, augmented and virtual reality, and embodied artificial intelligence (AI) depend on the ability to reconstruct complex signals from sparse observations. These applications are characterized by incomplete measurements and limited computational resources. Traditional approaches to digital hardware face the following challenges: explicit signal representations require heavy sampling and storage, data movement across the von Neumann bottleneck...

Beam-Plasma Collective Oscillations in Intense Charged-Particle Beams: Dielectric Response Theory, Langmuir Wave Dispersion, and Unsupervised Detection via Prometheus
arXiv:2603.10457v4 Announce Type: replace-cross Abstract: We develop a theoretical and computational framework for beam-plasma collective oscillations in intense charged-particle beams at intermediate energies (10-100 MeV). In Part I, we formulate a kinetic field theory governed by the Vlasov-Poisson system, deriving the Lindhard dielectric function and random phase approximation (RPA) polarization tensor for three beam distribution functions. We prove via the dielectric function...
