Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Pulse pressure index (pulse pressure/systolic pressure) may be better than pulse pressure for assessment of cardiovascular outcomes

Medical Hypotheses, 2009
Pulse pressure (PP) is emerging as a major pressure predictor of cardiac disease. However, there are two major limitations for PP as an evaluation index. First, PP has alterability in the same individual. Second, PP is "floating", it has no relation to an absolute BP level.

Diastolic pressure, systolic pressure, or pulse pressure?

Current Hypertension Reports, 2000
Diastolic pressure, systolic pressure, and pulse pressure have all been assigned the role of the best predictor of cardiovascular events during the 20th century. At the dawn of the new millennium, concepts that draw attention to vascular mechanics reconcile the seemingly conflicting results of epidemiologic studies, better define the hypertensive ...
