Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Cognitive disorders are common in older persons with seizures (PWS). Cognitive disorders are often associated with impaired Instrumental Activities of Daily Living (IADLs). However, the effects of seizures on IADLs remain unexplored.

Overview of Radar Jamming Waveform Design
Remote SensingRadar jamming waveform design is a vital part of radar jamming. Over seven to eight decades of evolution, the field has transitioned from noise signal design to coherent jamming signal design, resulting in a multitude of complex jamming styles capable of

Quasi-Coherent Noise Jamming to LFM Radar Based on Pseudo-random Sequence Phase-modulation [PDF]
Radioengineering, 2015 A novel quasi-coherent noise jamming method is proposed against linear frequency modulation (LFM) signal and pulse compression radar. Based on the structure of digital radio frequency memory (DRFM), the jamming signal is acquired by the pseudo-random ...

, 2019 The shear-jamming of dense suspensions can be strongly affected by molecular-scale interactions between particles, e.g. by chemically controlling their propensity for hydrogen bonding. However, hydrogen bonding not only enhances interparticle friction, a

Cooperative Jamming for Secure Communications in MIMO Relay Networks [PDF]
, 2011 Secure communications can be impeded by eavesdroppers in conventional relay systems. This paper proposes cooperative jamming strategies for two-hop relay networks where the eavesdropper can wiretap the relay channels in both hops.

A thermodynamic unification of jamming [PDF]
Nature Physics, 2008 Fragile materials ranging from sand to fire-retardant to toothpaste are able to exhibit both solid and fluid-like properties across the jamming transition. Unlike ordinary fusion, systems of grains, foams and colloids jam and cease to flow under conditions that still remain unknown.

Genetic Diversity and Expanded Phenotypes in Dystonia: Insights From Large‐Scale Exome Sequencing
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Dystonia is one of the most prevalent movement disorders, characterized by significant clinical and etiological heterogeneity. Despite considerable heritability (~25%), the etiology in most patients remains elusive. Moreover, understanding correlations between clinical manifestations and genetic variants has become increasingly ...

How Generic are the Robust Theoretical Aspects of Jamming in Hard Sphere Models?
, 2017 In very recent work the mean field theory of the jamming transition in infinite dimensional hard spheres models was presented. Surprisingly, this theory predicts quantitatively numerically determined characteristics of jamming in two and three dimensions.

Variable-cell method for stress-controlled jamming of athermal, frictionless grains [PDF]
, 2014 A new method is introduced to simulate jamming of polyhedral grains under controlled stress that incorporates global degrees of freedom through the metric tensor of a periodic cell containing grains.
