The intent recognition is an essential algorithm of any conversational AI application. It responsible for the classification input message into meaningful classes. In many bot development platforms, we can configure NLU pipeline. Several services are currently available as API, or choose from open-source alternatives. However, there no comparison and algorithms. Many factors make selection righ...

Proceeding from the scattered field expansion in cylindrical harmonics, we define partial invisibility or cloaking as suppression of finitely many lowest-order harmonics. We show that for benchmark structures (a dielectric rod and a perfectly conducting cylinder circular cross section covered by concentric layer), such multiple can be achieved. For this purpose, prove solvability explicitly det...

Chronic pain is one of the most prevalent and costly problems in the United States today. Traditional medical treatments for it, though, have not been consistently efficacious or cost-effective. In contrast, more recent comprehensive pain programs (CPPs) have been shown to be both therapeutically efficacious and cost-effective. The present study reviews available evidence demonstrating the ther...
