Predicting Epileptogenic Tubers in Patients With Tuberous Sclerosis Complex Using a Fusion Model Integrating Lesion Network Mapping and Machine Learning

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate localization of epileptogenic tubers (ETs) in patients with tuberous sclerosis complex (TSC) is essential but challenging, as these tubers lack distinct pathological or genetic markers to differentiate them from other cortical tubers.

Compact Monolithic 3D-Printed Wideband Filters Using Pole-Generating Resonant Irises

IEEE Journal of Microwaves, 2023
The design concept of a pole-generating resonant iris is demonstrated in rectangular waveguide filters in this paper. Different from conventional reactive iris, the resonant iris can generate an extra transmission pole without increasing the number of ...

Characteristic analysis of resonant filter

Electronics and Communications in Japan, 2007
AbstractUsually, the resonant filter is composed of several resonators made of dielectric and metal, and is applied to high‐frequency bandpass filters (BPFs). Although a resonant filter has a simple structure, it is very difficult to obtain the optimal geometry experimentally, because its filter characteristic is greatly influenced by the material and ...
