Deep Learning Inverse Design of Phase‐Change Reconfigurable Terahertz Metadevices for Multidimensional Secure Communication

open access: yesAdvanced Materials, EarlyView.
A deep learning inverse‐design framework is established to create versatile reconfigurable terahertz metadevices. By synergizing deep learning with phase‐change materials, this approach enables on‐demand customization of multidimensional electromagnetic responses.

An introduction to wave intensity analysis

Medical and Biological Engineering and Computing, 2009
Wave intensity analysis applies methods first used to study gas dynamics to cardiovascular haemodynamics. It is based on the method of characteristics solution of the 1-D equations derived from the conservation of mass and momentum in elastic vessels.

Wave intensity wall analysis: a novel noninvasive method to measure wave intensity [PDF]

open access: yesHeart and Vessels, 2009
Wave intensity analysis is a concept providing information about the interaction of the heart and the vascular system. Originally, the technique was invasive. Since then new noninvasive methods have been developed. A recently developed ultrasound technique to estimate tissue motion and deformation is speckle-tracking echocardiography.

Pulmonary arterial wave intensity analysis in health and disease. [PDF]

open access: yes, 2010
Wave intensity analysis (WIA) is a time-domain technique utilising high fidelity pressure and velocity measurements to determine the intensity, direction, type and timing of waves that may simultaneously exist. Travelling wavefronts represent elemental units of energy transmitted within and between the heart and blood vessels.
