Generalized Dimension Distortion under Mappings of Sub-Exponentially Integrable Distortion
, 2010 We prove a dimension distortion estimate for mappings of sub-exponentially integrable distortion in Euclidean spaces, which is essentially sharp in the ...

A Large Deviations Approach to Secure Lossy Compression
, 2015 We consider a Shannon cipher system for memoryless sources, in which distortion is allowed at the legitimate decoder. The source is compressed using a rate distortion code secured by a shared key, which satisfies a constraint on the compression rate, as ...

Universal distortion function for steganography in an arbitrary domain
EURASIP Journal on Information Security, 2014 Currently, the most successful approach to steganography in empirical objects, such as digital media, is to embed the payload while minimizing a suitably defined distortion function.

Materials & Design (1980-2015), 2020 Due to rapid solidification of melted powders in metal additive manufacturing processes and high thermal gradients, large residual stresses are created in the build. This can lead to undesired distortions as well as crack initiation. The main aim of this

Embedding Metrics into Ultrametrics and Graphs into Spanning Trees with Constant Average Distortion [PDF]
, 2006 This paper addresses the basic question of how well can a tree approximate distances of a metric space or a graph. Given a graph, the problem of constructing a spanning tree in a graph which strongly preserves distances in the graph is a fundamental ...

Spatial Characteristics of Distortion Radiated from Antenna Arrays with Transceiver Nonlinearities
, 2018 The distortion from massive MIMO (multiple-input--multiple-output) base stations with nonlinear amplifiers is studied and its radiation pattern is derived. The distortion is analyzed both in-band and out-of-band.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
