Epilepsia, EarlyView.Abstract Objective Memory problems are comorbid with temporal lobe epilepsy (TLE). Animal models of TLE reveal impairments in spatial firing fields of hippocampal place cells, providing a potential neural substrate for memory problems. Each subfield of the hippocampus carries out unique aspects of spatial memory, yet little is known about how ...

Epilepsia Open, EarlyView.Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Ultrasound‐Assisted Epoxy Resin Curing Monitored by Impedance Spectroscopy
Polymer Engineering &Science, EarlyView.Ultrasound enhances epoxy cure rates via localized heating without altering cure kinetics. Impedance spectroscopy provides a direct, non‐destructive measure of cure progression, enabling accurate mapping of degree of cure in real time. ABSTRACT Epoxy resins are widely used in aerospace and automotive manufacturing as structural adhesives and matrices ...
