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 ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...
