Constructing Low-latency Involutory MDS Matrices with Lightweight Circuits

2019 · Lirias

MDS matrices are important building blocks providing diffusion functionality for the design of many symmetric-key primitives. In recent years, continuous efforts are made on the construction of MDS matrices with small area footprints in the …

Entanglement-Assisted Coding for Arbitrary Linear Computations Over a Quantum MAC

2025 · arXiv (Cornell University)

We study a linear computation problem over a quantum multiple access channel (LC-QMAC), where $S$ servers share an entangled state and separately store classical data streams $W_1,\cdots, W_S$ over a finite field $\mathbb{F}_d$. A user …

HybridSeg: An Efficient Multi-Scale Mamba Architecture for Real-Time Semantic Segmentation in Railway Safety Monitoring Systems

2025 · Preprints.org

Real-time semantic segmentation in railway safety monitoring presents significant computational challenges for edge-deployed vision systems, where accurate object detection directly impacts operational safety under strict resource constraints. Existing approaches struggle to achieve optimal trade-offs between …
