High internal phase Pickering emulsion (HIPPE) stabilized by heat induced soy protein isolate aggregates (HSPI) alone had limited stability and poor 3D printing performance. While there is few research about HIPPE stabilized by HSPI and polysaccrides at neutral pH condition, where HSPI and ĸ-carrageenan (CG) were combined to fabricate HIPPE in this research. It was found that the incorporation of CG significantly decreased the droplet size and improved the storage stability of the resulting HIPPE.

Quantitative physics-physiology relationship modeling of human emotional response to Shu music.

Front Psychol

October 2024

Center for Informational Biology, Key Laboratory for NeuroInformation of Ministry of Education, School of Life Science and Technology, University of Electronic Science and Technology of China, Chengdu, China.

Music perception is one of the most complex human neurophysiological phenomena invoked by sensory stimuli, which infers an internal representation of the structured events present in a piece of music and then forms long-term echoic memory for the music. An intrinsic relationship between the basic acoustic property (physics) of music and human emotional response (physiology) to the music is suggested, which can be statistically modeled and explained by using a novel notion termed as quantitative physics-physiology relationship (QPPR). Here, we systematically analyzed the complex response profile of people to traditional/ancient music in the Shu area, a geographical concept located in the Southwest China and one of three major origins of the Chinese nation.
