Explanatory Diagnosis: Conjecturing Actions to Explain Observations

Our concern in this paper is with conjecturing diagnoses to explain what happened to a system, given a theory of system behaviour and some observed (aberrant) behaviour. We characterize what happened by introducing the notion of explanatory diagnoses in the language of the situation calculus. Explanatory diagnosesconjecture sequencesof actions to account for a change in system behaviour. We sho...

The tracheotomy punch for urgent tracheotomy.

Tracheotomy is a commonly performed surgical technique used for long-term mechanical ventilation, upper airway obstruction, need for pulmonary toilet, and as an adjunct to surgery where ventilation is anticipated. Urgent tracheotomy may be performed when difficulty is encountered during an elective tracheotomy, or when cricothyroidotomy is impossible or contraindicated due to distorted anatomy ...

Despite being a life-saving measure, tracheotomy-related mortality rates range from 0.5 to 3.6%, and this procedure is not without significant and sometimes frequent complications. Techniques regarding pediatric tracheotomy vary from surgeon to ...

The reason is that explanatory indispensability in and of itself turns out to be insufficient for justifying the ...
