Biomarkers of Peripheral Fatigue in Subjects with Vascular and Neurological Motor Disabilities During an Incremental Treadmill Test Using Near-Infrared Spectroscopy

Peripheral artery disease (PAD) is a progressive atherosclerotic disease that affects textgreater8 million Americans.1 Symptoms of PAD are caused by insufficient arterial blood flow to the lower extremities, which often results in ischemia-induced, …

Feeling Positive? Predicting Emotional Image Similarity from Brain Signals

The present notion of visual similarity is based on features derived from image contents. This ignores the users' emotional or affective experiences toward the content, and how users feel when they search for images. Here we consider valence, a …

Impact of blunted cerebral oxygenation on COPD patients’ functional performance

Introduction: Albeit physical activity (PA) has an important role concerning the health of patients with chronic respiratory diseases, it remains unclear how PA patterns compare among different diseases. Aims: To compare PA levels of 3 major chronic …

Affective Relevance: Inferring Emotional Responses via fNIRS Neuroimaging

Information retrieval (IR) relies on a general notion of relevance, which is used as the principal foundation for ranking and evaluation methods. However, IR does not account for more a nuanced affective experience. Here, we consider the emotional …
