OBJECTIVES To determine (1) whether heart rate variability (HRV) was a sensitive and reliable measure in mental effort tasks carried out by healthy seniors and (2) whether non-linear approaches to HRV analysis, in addition to traditional time and frequency domain approaches were useful to study such effects. METHODS Forty healthy seniors performed two(More)
PURPOSE Several studies have suggested that interictal regional delta slowing (IRDS) carries a lateralizing and localizing value similar to interictal spikes and is associated with favorable surgical outcomes in patients with temporal lobe epilepsy (TLE). However, whether IRDS reflects structural dysfunction or underlying epileptic activity remains(More)
PURPOSE To determine the incidence, duration, risk factors for, and clinical correlates of postictal generalized electroencephalography (EEG) suppression (PGES), and to further delineate the significance of PGES in the pathogenesis of sudden unexpected death in epilepsy (SUDEP). METHODS We retrospectively reviewed the video-EEG studies of 109 consecutive(More)
In this paper we propose a methodology to control a novel class of actuators that we called passive noise rejection variable stiffness actuators (pnrVSA). Differently from nowadays classical VSA designs, this novel class of actuators mimics the human musculoskeletal ability to increase noise rejection without relying on feedback. To fully highlight the(More)
Due to some limitations of mechanical solution for automation of front end loaders, specifically self-leveling task, we investigate here the sensor-based solution. We present a model of front end loaders and the comparison of different controllers to realize this task. The best performance is observed from the controller comprising linear terms,(More)
A 26-year-old woman was brought to the emergency department following several episodes of seizures. The patient’s friend witnessed several 15-minute episodes of sudden jerks and tremors of her right arm during which the patient bit her tongue, had word-finding difficulty, had horizontal eye deviation, and was incontinent of urine. She became unresponsive(More)
Heart rate variability (HRV) is frequently used to measure autonomic nervous system (ANS) activity. However, little is known about the mechanism underlying pharmacologically induced changes in HRV. Previous research has shown that nicotine exposure stimulates the ANS, mediating a wide spectrum of physiological and behavioral effects, including altered(More)
