Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.

A Self-Adaptive Progressive Support Selection Scheme for Collaborative Wideband Spectrum Sensing
Sensors, 2018 The sampling rate of wideband spectrum sensing for sparse signals can be reduced by sub-Nyquist sampling with a Modulated Wideband Converter (MWC). In collaborative spectrum sensing, the fusion center recovers the spectral support from observation and ...

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Subtotal hippocampal resection can leave residual hippocampal tissue, yet the immediate postoperative electrophysiologic evolution of such remnants is unknown. We describe a patient with drug‐resistant temporal lobe epilepsy in whom a hippocampal remnant was continuously monitored using a responsive neurostimulator (RNS) following subtotal ...

Millimeter wave p–i–n-diode switching controlled devices
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2016 The paper presents the results of research and development of concentrated type p–i–n-diodes switches providing the switching time units of nanoseconds. To increase lock losses of (~40 dB) the authors use a cascade connection of diodes into waveguide and

On the Accuracy of Transmission Loss Measurements [PDF]
The Journal of the Acoustical Society of America, 1960 One of the authors [M. Heckl and K. Seifert, Acustica 8, 212–220 (1958)] recently has described the performance of a wall between two, one-dimensional rooms (tubes). It was found that the TL was influenced by the relative lengths of the two rooms and by the sound absorption of the rooms.
