Rich feature extraction is essential to train a good machine learning (ML) framework. These features are generally extracted separately from each modality. We hypothesize that richer can be learned when modalities jointly explored. joint modality perform better than those individual modalities. study two modalities, physiological signals – Electrodermal activity (EDA) and electrocardiogr...

It has been suggested that psychosocial stress influences situational fluctuations of tic frequency. However, evidence from experimental studies is lacking. The current study investigated the effects of the Trier Social Stress Test (TSST-C) on tic frequency in 31 children and adolescents with tic disorders. A relaxation and a concentration situation served as control conditions. Patients were a...

Thin silicon dioxide films have been studied as a function of deposition parameters and annealing temperatures. Films were deposited by tetraethoxysilane (TEOS) dual-frequency plasma enhanced chemical vapor deposition with different time interval fractions of high-frequency and low-frequency plasma depositions. The samples were subsequently annealed up to 930 ◦C to investigate their stress beha...

BACKGROUND Although mental stress is commonly considered to be an important trigger factor for migraine, experimental evidence for this belief is yet lacking. OBJECTIVE To study the temporal relationship between changes in stress-related parameters (both subjective and objective) and the onset of a migraine attack. METHODS This was a prospective, ambulatory study in 17 migraine patients. We...

Psychological stress is a risk factor for hypertension and coronary artery disease. The purpose of this study was to assess the impact of real life stressor, that of stress among first year medical students on cardiac autonomic regulation. Stress levels in 36 non-smoking, healthy first year medical students of either gender were assessed on a self-rating scale. Cardiac autonomic regulation was ...

UNLABELLED Stress is a complex phenomenon coordinated by two main neural systems: the hypothalamic-pituitary-adrenal system with cortisol as classical stress biomarker and the autonomic nervous system with heart rate variability (HRV) as recently suggested stress marker. To test low HRV (5 minute measurements) as stress indicator in young children (5-10 y), associations with self-reported chron...

BACKGROUND Emerging evidence indicates that individuals reporting more positive affect are healthier and live longer. The aim of this study was to examine if positive states of mind moderates the effect of perceived stress on psychological functioning and perceived health. METHODS A cross-sectional sample, n = 382, responded to questions regarding perceived stress, depression, anxiety, percei...

Impaired cerebral autoregulation during marked reductions in arterial blood pressure may contribute to heat stress-induced orthostatic intolerance. This study tested the hypothesis that passive heat stress attenuates dynamic cerebral autoregulation during pronounced swings in arterial blood pressure. Mean arterial blood pressure (MAP) and middle cerebral artery blood velocity were continuously ...
