(2023-03-01)
Article
Open AccessApplying complex mathematical models of physiological systems is challenging due to the large number of parameters. Identifying these parameters through experimentation is difficult, and although procedures for fitting and ... -
A one-year hospital-based prospective COVID-19 open-cohort in the Eastern Mediterranean region: The Khorshid COVID Cohort (KCC) study
(Public Library of Science (PLOS), 2020-11-05)
Article
Open AccessThe COVID-19 is rapidly scattering worldwide, and the number of cases in the Eastern Mediterranean Region is rising. Thus, there is a need for immediate targeted actions. We designed a longitudinal study in a hot outbreak ... -
A real-time and convex model for the estimation of muscle force from surface electromyographic signals in the upper and lower limbs
(Frontiers Media SA, 2023-02)
Article
Open AccessLow-volume lung injury encompasses local concentration of stresses in the vicinity of collapsed regions in heterogeneously ventilated lungs. We aimed to study the effects on ventilation and perfusion distributions of a ... -
A real-time method for decoding the neural drive to muscles using single-channel intra-muscular EMG recordings
(2017-09-01)
Article
Open AccessThe neural command from motor neurons to muscles — sometimes referred to as the neural drive to muscle — can be identified by decomposition of electromyographic (EMG) signals. This approach can be used for inferring the ... -
A synchronization system for the analysis of biomedical signals recorded with different devices from mechanically ventilated patients
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference lecture
Restricted access - publisher's policyConducting research associated with mechanically ventilated patients often requires the recording of several biomedical signals to dispose of multiple sources of information to perform a robust analysis. This is especially ... -
Absolute mortality risk assessment of COVID-19 patients: the Khorshid COVID Cohort (KCC) study
(2021-12-01)
Article
Open AccessBackground: Already at hospital admission, clinicians require simple tools to identify hospitalized COVID-19 patients at high risk of mortality. Such tools can significantly improve resource allocation and patient management ... -
Acoustic analysis of snoring sound in patients with simple snoring and obstructive sleep apnoea
(1996-11-09)
Article
Open AccessSnoring, a symptom which may indicate the presence of the obstructive sleep apnoea syndrome (OSA), is also common in the general population. Recent studies have suggested that the acoustic characteristics of snoring sound ... -
Acute sleep deprivation induces a local brain transfer information increase in the frontal cortex in a widespread decrease context
(2016-04-01)
Article
Open AccessSleep deprivation (SD) has adverse effects on mental and physical health, affecting the cognitive abilities and emotional states. Specifically, cognitive functions and alertness are known to decrease after SD. The aim of ... -
Alterations in EEG connectivity in healthy young adults provide an indicator of sleep depth
(2019-06-11)
Article
Open AccessCurrent sleep analyses have used electroencephalography (EEG) to establish sleep intensity through linear and nonlinear measures. Slow wave activity (SWA) and entropy are the most commonly used markers of sleep depth. The ... -
An accurate and real-time method for resolving superimposed action potentials in multiunit recordings
(2023-01)
Article
Restricted access - publisher's policyObjective : Spike sorting of muscular and neural recordings requires separating action potentials that overlap in time (superimposed action potentials (APs)). We propose a new algorithm for resolving superimposed action ... -
An improved dynamic model for the respiratory response to exercise
(2018-02-07)
Article
Open AccessRespiratory system modeling has been extensively studied in steady-state conditions to simulate sleep disorders, to predict its behavior under ventilatory diseases or stimuli and to simulate its interaction with mechanical ... -
