Uplink Multi-User MIMO Testbed Implementation in OpenAirInterface
This paper presents our results on building an Uplilnk Multi-User Multiple Input Multiple Output (MU-MIMO) testbed using OpenAirInteface and software-defined radios (SDRs). We overview the theory and detail the firmware implementation, hardware...
Performance Analysis of Cell-Free Massive MIMO under Imperfect LoS Phase Tracking
A unified Rician fading model and MMSE-optimal framework for performance analysis of distributed massive MIMO that bridges the gap between idealized assumptions and practical tracking limitations in cell-free networks.
Pt–Re dehydrogenation catalysts synthesized via solvent deficient precipitation
This study demonstrates the feasibility of producing Pt–Re/Al2O3 catalysts via the scalable solvent deficient precipitation method achieving enhanced performance in the dehydrogenation of liquid organic hydrogen carriers. Successful 10-fold...
A consolidated and accessible security proof for finite-size decoy-state quantum key distribution
In recent years, quantum key distribution (QKD) has evolved from a scientific research field to a commercially available security solution, supported by mathematically formulated security proofs. However, since the knowledge required for a full...
Deterministic Ray-Launching Tool for THz Propagation Modeling
In this paper, we introduce a deterministic ray-launching (RL) tool for THz propagation modeling. The tool includes a library of electromagnetic material properties, obtained from measurements of common building materials and uses geometric and...

R3GW: Relightable 3D Gaussians for Outdoor Scenes in the Wild
In this paper, we present R3GW, a novel method that learns a relightable 3DGS representation of an outdoor scene captured in the wild. Our approach separates the scene into a relightable foreground and a non-reflective background (the sky), using...
Phys-3D: Physics-Constrained Real-Time Crowd Tracking and Counting on Railway Platforms
We propose a physics-constrained tracking framework that unifies detection, appearance, and 3D motion reasoning in a real-time pipeline. Our approach integrates a transfer-learned YOLOv11m detector with EfficientNet-B0 appearance encoding within...
