Time-dependent properties of chemical signals are probably crucially important to many animals, but little is known about the dynamics of chemoreceptors. Behavioral evidence of dynamic sensitivity includes the control of moth flight by pheromone plume structure, and the ability of some blood-sucking insects to detect varying concentrations of carbon dioxide, possibly matched to host breathing r...

Drowning is the major cause of death in self-contained underwater breathing apparatus (SCUBA) diving. This study proposes an embedded system with a live and light-weight algorithm which detects the breathing of divers through the analysis of the intermediate pressure (IP) signal of the SCUBA regulator. A system composed mainly of two pressure sensors and a low-power microcontroller was designed...

Introduction T2-weighted (T2w) cardiac MR imaging has established reputation as a sensitive technique to depict myocardial edema related to acute infarction. Together with delayed enhancement technique, T2w demonstrated valuable clinical potentials to differentiate acute damage from chronic infarction [1]. To minimize the myocardial signal loss caused by through-plane motion, T2w can be perform...

Respiration is an essential and primary mechanism for speech production. We first inhale then produce while exhaling. When we run out of breath, stop speaking inhale. Though this process involuntary, production involves a systematic outflow air during exhalation characterized by linguistic content prosodic factors the utterance. Thus respiration are closely related, modeling relationship makes ...

BACKGROUND Congenital central hypoventilation syndrome (CCHS) is a rare neuro-respiratory disorder associated with mutations of the PHOX2B gene. Patients with this disease experience severe hypoventilation during sleep and are consequently ventilator-dependent. However, they breathe almost normally while awake, indicating the existence of cortical mechanisms compensating for the deficient brain...

BACKGROUND Accurate blood pressure (BP) measurement depends on the reliability of oscillometric cuff pressure pulses (OscP) and Korotkoff sounds (KorS) for automated oscillometric and manual techniques. It has been widely accepted that respiration is one of the main factors affecting BP measurement. However, little is known about how respiration affects the signals from which BP measurement is ...

conclusions cmr with stir sequences, free breathing sequences and late gadolinium imaging can prove extremely useful for diagnosing constrictive pericarditis. case presentation a 77-year-old man from a country with high incidence of tuberculosis presented with severe dyspnea. echocardiography revealed a small left ventricle with normal systolic and mildly impaired diastolic function. left heart...
