Monthly or menstrual? A scoping review of catamenial epilepsy and non‐menstrual seizure rhythms
Epilepsia, EarlyView.Abstract Objective Despite the reported high prevalence of catamenial epilepsy (CE), the condition remains poorly defined, with lack of consensus on what entails a menstrual‐related seizure exacerbation. Emerging evidence of multiday cycles of seizure activity, including about‐monthly cycles, present in both men and women, further confound the ...

Proposition of Microrover System for Lunar Exploration
Journal of Robotics and Mechatronics, 2000 We developed a lightweight, low-power microrover for surface exploration in space. Such a rover must travel safely over long distances and periods in unfamiliar terrain. We present an exploration mission, scientific significance, requirements, and technology of a rover, proposing mobility using 4 wheels and 1 supported wheel whose suspension is simple ...
