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.

Characterization of ultra high power laser beam PV converters [PDF]

AIP Conference Proceedings, 2019
Edge illuminated laser power PV converters of near-IR region (800-850nm) were made by liquid phase epitaxy. The developed converters are based on the GaAs active region with a wide (50-100 µm) AlGaAs waveguide layer. Gradient Al content in the waveguide layer ensured effective light collection on the p-n junction.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Evaluation of Photovoltaic Laser Power Converters for Non-Uniform Laser Irradiance Profiles

, 2022
The non-uniform irradiance of fiber lasers influences the performance of power-by-light systems. We analyze the non-uniformity in both single and triple junction power converters in addition to other parameters that could reduce the efficiency such as manufacturing tolerances or series resistance effect.
