Temporal Divergence of True and False Alarms in Pediatric Nocturnal Seizure Monitoring

Annals of Clinical and Translational Neurology, EarlyView.
The early‐morning surge in false seizure alarms supports exploring time‐ or state‐dependent detection thresholds to reduce false detections. ABSTRACT Seizure detection devices can improve the safety of children with epilepsy, yet high false alarms limit their clinical applicability.

Time-Varying Kelvin Wake Model and Microwave Velocity Observation

Sensors, 2020
In the synthetic aperture radar (SAR) imaging of ship-induced wakes, it is difficult to obtain the Doppler velocity of a Kelvin wake due to the lack of time-varying wake models and suitable radar equipment.

Juvenile Huntington Disease With Cerebellar‐Predominant Atrophy Identified by Genome Sequencing

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Juvenile Huntington disease accounts for a small fraction of Huntington disease cases and is driven by the largest trinucleotide repeat expansions. We describe a 6‐year‐old boy with progressive global regression, generalized dystonia, and epilepsy, in whom serial imaging showed striking cerebellar‐predominant atrophy with an initially normal ...

Assessment of wind turbine wake definitions for quantifying unsteady wake characteristics

Journal of Physics: Conference Series
Abstract Mitigation of wake effects in wind farms often relies on predictive wake models, which are typically developed using parameters calibrated from transient wind turbine wake data. Therefore, accurate identification of instantaneous turbine wakes is essential for improving wind farm yield. Despite the wide range of proposed wake

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

Arthritis Care &Research, EarlyView.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...
