Security researchers are warning that design flaws in the Comet web browser could let attackers quietly take over user ...

Why the web as we know it may fade and what AI, personal agents, and data interfaces mean for publishers, SEO, and commerce.

Abstract: We design a quantum-dot single-photon source with a defect-based photonic crystal cavity on a SiN waveguide that subdues crosstalk from resonant excitation and has >90% coupling efficiency.

Abstract: This work studies the transceiver design and convergence performance analysis for the hierarchical modulation (HM) systems with protograph-based low-density parity-check (P-LDPC) codes.
