Everything Is Illuminated

We study geometrical properties of translation surfaces: the finite blocking property, bounded blocking property, and illumination properties. These are elementary properties which can be fruitfully studied using the dynamical behavior of the SL(2,R)-action on the moduli space of translation surfaces. We characterize surfaces with the finite blocking property and bounded blocking property, comp...

Is Timing Everything?

Thank you Ben and AmSECT for organizing this conference. And thank you all for showing up on Saturday morning. My objectives for this presentation are to review the current knowledge of time spent below critical thresholds and more specifically the relationship between low oxygen delivery and organ function following cardiopulmonary bypass (CPB). Additionally, we will investigate the time–dose ...

Support is everything

Inadequate support for placement of balloons or stents continues to be a problem in interventional cardiology. We read with interest the report on MotherDaughter-Granddaughter Double Guide Liner Technique for Delivering Stents Past Multiple Extreme Angulations. The authors cleverly describe the use of a 6 French Guide Liner inside an 8 French Guide Liner to cross two difficult to cross saphenou...
