Simultaneous monitoring of activity and heart rate variability in depressed patients: A pilot study using a wearable monitor for 3 consecutive days

open access: yesNeuropsychopharmacology Reports, Volume 42, Issue 4, Page 457-467, December 2022., 2022
By using a wearable sensor we examined 3‐dimensional acceleration and heart rate variability (HRV) simultaneously in depressive episode of mood disorders. We found reduced activity and altered HRV indices in depressed patients, compared with healthy participants, particularly in males. Moreover, we found that sympathetic load during sleep significantly

Cosmic Inflation and Genetic Algorithms

open access: yesFortschritte der Physik, Volume 71, Issue 1, January 2023., 2023
Abstract Large classes of standard single‐field slow‐roll inflationary models consistent with the required number of e‐folds, the current bounds on the spectral index of scalar perturbations, the tensor‐to‐scalar ratio, and the scale of inflation can be efficiently constructed using genetic algorithms.

An experimental flow regime map to dynamically structure gas–solid bubbling fluidized beds

open access: yesAIChE Journal, EarlyView.
Abstract Employing oscillatory gas flows to create ordered bubble dynamics in fluidized beds represents a promising approach in reactor design, enhancing efficiency, scalability, and control. This study reports an extensive experimental campaign that identifies the operational regime for structuring Geldart B fluidized beds, introducing a novel pattern

A Hybrid Haptic Device Integrating Pneumatic and Electromagnetic Actuators for Realistic Tactile Signal Feedback

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel soft, wearable haptic device integrates pneumatic and electromagnetic actuators to improve tactile signal transmission. Optimized with finite elements method simulations, it accurately transmits high‐frequency (texture) and low‐frequency (shape) signals. Experimental validation shows its suitability for applications in master–slave robotics and
