A Real Orthogonal Space-Time Coded UWB Scheme for Wireless Secure Communications
EURASIP Journal on Wireless Communications and Networking, 2009 Recent research reveals that information security and information-hiding capabilities can be enhanced by proper exploitation of space-time techniques. Meanwhile, intrinsic properties of ultra-wideband (UWB) signals make it an outstanding candidate for ...

Fundamental Limits of Communication with Low Probability of Detection [PDF]
, 2016 This paper considers the problem of communication over a discrete memoryless channel (DMC) or an additive white Gaussian noise (AWGN) channel subject to the constraint that the probability that an adversary who observes the channel outputs can detect the

Linear Programming Detection and Decoding for MIMO Systems [PDF]
, 2006 We develop an efficient linear programming detector (LPD) for multiple-input multiple-output (MIMO) systems. Instead of using the usual l2 norm, our proposed LPD uses the l1 norm as the detection metric, resulting in a mixed-integer linear program (MILP).

Fundamental limits of quantum-secure covert optical sensing [PDF]
, 2017 We present a square root law for active sensing of phase $\theta$ of a single pixel using optical probes that pass through a single-mode lossy thermal-noise bosonic channel.

Cue validity and object-based attention [PDF]
, 2004 In a previous study, Egly, Driver, and Rafal (1994) observed both space- and object-based components of visual selective attention. However, the mechanisms underlying these two components and the relationship between them are not well understood.

Fluctuations in instantaneous frequency predict alpha amplitude during visual perception. [PDF]
, 2017 Rhythmic neural activity in the alpha band (8-13 Hz) is thought to have an important role in the selective processing of visual information. Typically, modulations in alpha amplitude and instantaneous frequency are thought to reflect independent ...

Extracellular vesicle proteomics identifies novel blood biomarkers for the early diagnosis of status epilepticus. [PDF]
EpilepsiaAbstract Objective This study was undertaken to identify novel blood‐based biomarkers associated with the early diagnosis of status epilepticus (SE) by exploring proteomic alterations in plasma extracellular vesicles (EVs). Methods We conducted an observational and prospective study in a two‐phase design: a discovery proteomic analysis of plasma EVs ...

Quinolone tolerance in <i>Escherichia coli</i> due to defects in the adenosine ribonucleotides <i>de novo</i> biosynthesis pathway. [PDF]
mLifeAbstract Central carbon metabolism is thought to link reactive oxygen species (ROS) with antibiotic‐mediated bacterial death. During enrichment screening of Escherichia coli with the first‐generation quinolone oxolinic acid, unstable antibiotic‐tolerant mutants containing deficiencies in purB were obtained.
