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 ...

Resting energy expenditure measured by whole‐room and portable indirect calorimetry in adults with breast cancer: A comparison study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Accurate measurement of resting energy expenditure is essential for informing nutrition support and optimizing outcomes. However, gold standard methods for measuring resting energy expenditure are often unfeasible in clinical settings, and previous portable devices have lacked accuracy.

A wavelet‐based method for the assessment of hydrodynamic model behavior against observed sea level variability

Limnology and Oceanography: Methods, EarlyView.
Abstract Sea level outputs from hydrodynamic models are often assessed against tide gauge data by comparing the standard deviations of modeled and observed time series, and by calculating the Pearson correlation coefficient and centered root mean square error (cRMSE) between the two.

Toward Low‐Power Laser Refrigeration ‐ Cooling a Resonant WGM Crystalline Cavity

Laser &Photonics Reviews, EarlyView.
Laser refrigeration offers a method to cool solids to low temperatures by using only light. By illuminating bulk crystals doped with rare‐earth ions one can engineer the emitted fluorescent light to be at shorter wavelengths than the pump light ‐ thus extracting heat/phonons from the solid and cooling the crystals.

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 ...

Validity and agreement of bioelectrical impedance equations against dual energy X‐ray absorptiometry for muscle mass assessment in patients on hemodialysis: A cross‐sectional study

Nutrition in Clinical Practice, EarlyView.
Abstract Background Low muscle mass is common in patients on hemodialysis (HD), and bioelectrical impedance analysis (BIA) predictive equations have been proposed as an alternative for estimating muscle mass. This study aimed to analyze the validity and agreement of different BIA‐based prediction equations against dual energy X‐ray absorptiometry (DXA)
