Lossy Compression with Near-uniform Encoder Outputs
, 2016 It is well known that lossless compression of a discrete memoryless source with near-uniform encoder output is possible at a rate above its entropy if and only if the encoder is randomized.

Non-Adaptive Distributed Compression in Networks [PDF]
, 2013 In this paper, we discuss non-adaptive distributed compression of inter-node correlated real-valued messages. To do so, we discuss the performance of conventional packet forwarding via routing, in terms of the total network load versus the resulting ...

Bound States in the Continuum in Metasurface Absorbers: A Comparison with Metasurfaces
Advanced Photonics Research, EarlyView.Bound states in the continuum (BICs) offer a powerful mechanism for enhancing light–matter interactions. This work systematically investigates the radiation characteristics of BICs under both transmission and reflection configurations using multipolar analysis.
