A 3GPP Perspective on Spectrum Sharing for 5G-to-6G Migration: From LTE-NR DSS Lessons to MRSS Design
arXiv:2604.26853v2 Announce Type: replace Abstract: Dynamic spectrum sharing (DSS) played an important role in the 4G-to-5G transition by allowing 5G new radio (NR) to reuse legacy spectrum without immediate static refarming. Yet practical deployments also exposed the cost of coexistence of NR with long-term evolution (LTE), including overheads, control-channel bottlenecks, neighbor-cell interference, etc. As 6G begins to take shape, spectrum scarcity below 7 GHz is again making 5G-6G...
Dynamic FDD for Spectrum Sharing in Non-Terrestrial Networks
arXiv:2606.04849v1 Announce Type: new Abstract: Future 6G networks are envisioned to integrate low Earth orbit satellite mega-constellations to enable seamless global connectivity, particularly in underserved and remote areas. However, the deployment of dense mega-constellations introduces interference among satellites operating over shared frequency bands. This represents a rather new setup for studying spectrum sharing, which exacerbates the limited flexibility of conventional FDD systems...
MatMind: A Structure-Activity Knowledge-Driven Generative Foundation Model for Materials Science
Announce Type: cross Abstract: Progress in AI-driven crystal materials science has so far been carried by narrow architectures purpose-built for individual tasks -- graph neural networks for property prediction, diffusion and flow-matching models for crystal generation -- each excelling within its niche yet unable to act as a shared backbone across the full spectrum of materials problems. Generative large language models offer a fundamentally different paradigm, in which structural...
Dimensional Arousal and Categorical Gaze Instability: Uncoupling the Baseline Oculomotor Phenotypes of Autism and ADHD
Background: Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) share substantial clinical and physiological overlap. While naturalistic and sensory-driven paradigms increasingly capture evoked neurophysiological responses, the intrinsic baseline physiology of these conditions remains poorly defined. We aimed to characterize resting-state autonomic arousal and oculomotor stability across the ASD-ADHD spectrum using both continuous (RDoC) and categorical (DSM-5)...
Elon Musk's SpaceX aiming to raise $75bn in record IPO
Elon Musk's SpaceX aiming to raise $75bn in record IPO June 4, 2026SpaceX, the aerospace and satellite communications company headed by US tech billionaire Elon Musk, is planning to raise around $75 billion (€64.6 billion) through what would be a record-breaking initial public offering (IPO), according to a regulatory filing released Wednesday. SpaceX intends to offer 555,555,555 shares at an initial price of $135 per share in an offering which, based on approximately 13 billion shares...
Digital Twin-Assisted Adaptive Multi-Agent DRL for Intelligent Spectrum and Resource Management in Open-RAN UAV-Enabled 6G Networks
Announce Type: new Abstract: The evolution toward 6G wireless networks envisions a seamlessly intelligent, Open-RAN-enabled architecture where unmanned aerial vehicles (UAVs) play a pivotal role in extending coverage, enhancing resilience, and ensuring reliable connectivity for ground users deployment. However, efficiently managing spectrum and resources in such highly dynamic UAV-assisted environments remains a major challenge due to nonlinear system interactions, mobility-induced topology...
Don’t repeat 5G mistakes with 6G, plead mobile operators
A body that represents mobile operators wants the migration to 6G networks to be as smooth as possible, learning lessons from the fractious 5G introduction that has left countries like the UK with a less than satisfactory service. The Next Generation Mobile Networks Alliance (NGMN) says that 6G requires a different standardization approach in order to prevent complexity and market confusion, alongside a smooth and cost-effective migration path for its members. What exactly defines 6G is...
VaN3Twin: the Multi-Technology V2X Digital Twin with Ray-Tracing in the Loop
arXiv:2505.14184v3 Announce Type: replace Abstract: This paper presents VaN3Twin-the first open-source, full-stack Network Digital Twin (NDT) framework for simulating the coexistence of multiple Vehicle-to-Everything (V2X) communication technologies with accurate physical-layer modeling via ray tracing. VaN3Twin extends the ms-van3t simulator by integrating Sionna Ray Tracer (RT) in the loop, enabling high-fidelity representation of wireless propagation, including diverse Line-of-Sight (LoS)...
Set-Based Transformer for Atmospheric Compensation in Standoff LWIR Hyperspectral Imaging
Announce Type: new Abstract: Passive long-wave infrared (LWIR) hyperspectral imaging under a standoff geometry depends on atmospheric absorption and emission, as well as reflected radiance, thus making atmospheric compensation essential to get knowledge of a target of interest. Despite its importance, this compensation has been largely overlooked due to its practical and modeling difficulty.
Beyond FLOPs: Benchmarking Real Inference Acceleration of LLM Pruning under a GEMM-Centric Taxonomy
arXiv:2606.09080v1 Announce Type: new Abstract: Pruning has emerged as a dominant paradigm for accelerating large language model (LLM) inference, spanning a broad spectrum of methods that remove computation across tokens, layers, heads, dimensions, and attention patterns. Despite sharing the same objective, these pruning approaches induce fundamentally different execution behaviors, causing realized speedups to depend heavily on hardware and kernel implementations. Consequently, the...
