Evaluation of embolic deflection devices using optical particle tracking [PDF]
SPIE Proceedings, 2013 Trans-aortic valve replacement is a new endovascular procedure which has started to be used routinely in cardiac interventional suites. During such procedures a stent-like device containing new aortic valves is placed over the damaged ones, possibly causing calcifications to be dislodged and released in arteries leading to stroke.

Poleward Deflection of Storm Tracks [PDF]
Journal of the Atmospheric Sciences, 1998 An analysis of 11 years of European Centre for Medium-Range Weather Forecasts data focuses primarily on the vertically averaged high-frequency transients. The conclusions are discussed in the context of (a) the winter storm track, (b) monthly variability, and (c) interannual variability.

On Typhoon Track Deflections near the East Coast of Taiwan [PDF]
Monthly Weather Review, 2018 Typhoons with “deflection tracks” (DTs) within a 200-km distance of the mountainous island of Taiwan are examined. We analyze 84 landfalling typhoons that compose 49 DT cases turning to the left-hand side, including 18 with very large deflection angles (DA > 20°) and another 7 having looped tracks (LTs).
