Cerebrovascular Disease 2: Stroke (DRAFT)
2018The video in this chapter explores cerebrovascular disease, and focuses on stroke. It discusses the definition of stroke as a sudden focal neurologic deficit that persists for more than 24 hours, as well as ischemic strokes (embolic, thrombotic, or due to hypoperfusion), and intraparenchymal hemorrhagic strokes.

Diesel Engine 2-Stroke Breathing for Aftertreatment Warm-Up
International Journal of Engine Research, 2021Since the introduction of diesel urea SCR technology, aftertreatment thermal management has become critical for maintaining SCR catalyst light-off and thereby low cumulative cycle NOx emissions. A novel diesel engine aftertreatment thermal management strategy is proposed which utilizes a 2-stroke breathing variable value actuation strategy to increase
