Philosophical Transactions of the Royal Society B: Biological Sciences, 2004 Waves through living systems are best characterized by their speeds at 20°C. These speeds vary from those of calcium action potentials to those of ultraslow ones which move at 1–10 and/or 10–20 nm s−1. All such waves are known or inferred to be calcium waves.

Are "EIT Waves" Fast-Mode MHD Waves?
, 2007 We examine the nature of large-scale, coronal, propagating wave fronts (``EIT waves'') and find they are incongruous with solutions using fast-mode MHD plane-wave theory.

Simplified radar architecture based on information metasurface
Nature CommunicationsModern radar typically employs a chain radio-frequency (RF)-digital architecture, imposing high costs, substantial hardware burdens, and integration challenges. Here, we propose a simplified radar architecture based on space-time-coding (STC) information

Reverse Doppler effect in backward spin waves scattered on acoustic waves
, 2009 We report on the observation of reverse Doppler effect in backward spin waves reflected off of surface acoustic waves. The spin waves are excited in a yttrium iron garnet (YIG) film. Simultaneously, acoustic waves are also generated.
