Information Models of Acupuncture Analgesia and Meridian Channels

open access: yesInformation, 2010
Acupuncture and meridian channels have been major components of Chinese and Eastern Asian medicine—especially for analgesia—for over 2000 years. In recent decades, electroacupuncture (EA) analgesia has been applied clinically and experimentally. However,

Sound Intensity of a Drum

open access: yesInternational Scholastic Journal of Science, 2012
A small steel ball was dropped onto the center of a bongo drum. The relationship between impact energy and the maximum amplitude of the sound produced upon impact was determined using release heights ranging from 5 to 70 cm. It was found that there was a

An Effective Method to Estimate Composition Amplitude of Spinodal Decomposition for Atom Probe Tomography Validated by Phase Field Simulations

open access: yes, 2012
Reasonable evaluation of composition amplitude in spinodal decomposition is a challenge to microanalysis of atom probe tomography, especially at early stages when phase separation is not prominent. This impedes quantitative analysis of spinodal structure
