Airway management is crucial in clinical anesthesia. Many complications associated with airway management result from unexpected difficult airway, but predicting a difficult airway is a major challenge. We investigated the efficacy of a new combined model including radiological indicators to predict difficult airway in patients undergoing surgery for cervical spondylosis, ...

Objective: The human pharyngeal airway during sleep is often modeled as a Starling resistor. However, inspiratory flow often decreases with increasing effort (negative effort dependence, NED), rather than remaining fixed as predicted by the Starling resistor model. In this study, we tested a major prediction of the Starling resistor model ...

Asthma develops from injury to the airways/lungs, stemming from airway inflammation (AI) and airway remodeling (AWR), both contributing to airway hyperresponsiveness (AHR). Airway epithelial damage has been identified as a new etiology of asthma but is not targeted by current treatments. Furthermore, it is poorly studied in currently used animal ...

Evolutionary approach to centralized multiple-faults diagnostics is extended to distributed transducer networks monitoring large experimental systems. Given a set of anomalies detected by the transducers, each instance of the multiple-fault problem is formulated as several parallel communicating sub-tasks running on different transducers, and thus solved one-by-one on spatially separated parallel ...
