Research of weak signal detection based on super‐regenerative chaotic oscillator
Electronics Letters, 2022 Under certain circumstances, chaos will occur in the super‐regenerative receiver. The gain of the receiver reaches the maximum and the receiver is immune to the external noise in this case. The concept of super‐regenerative chaotic oscillator is proposed,

Multiwalled ice helixes and ice nanotubes [PDF]
Proceedings of the National Academy of Sciences, 2006 We report six phases of high-density nano-ice predicted to form within carbon nanotubes (CNTs) at high pressure. High-density nano-ice self-assembled within smaller-diameter CNT (17,0) exhibits a double-walled helical structure where the outer wall consists of four double-stranded helixes, which resemble a DNA double helix, and the inner wall is a ...

MedEdPORTAL, 2011 Abstract This is a high-fidelity human patient simulation involving a severely hypothermic patient requiring invasive measures to rewarm the patient's core temperature. Altered physiology, along with medical and traumatic scenarios that put the patient at risk for severe hypothermia, is also addressed.
