In this paper, we propose enhanced constant power panning (CPP) law which improves sound localization accuracy for two channel and multi-channel surround speaker layouts. Conventional CPP laws have different sound direction from panning angle, especially when the speakers are spread out widely. To overcome this drawback, we define a target angle and derive it by using directional psychoacoustic...

Distance-Based Amplitude Panning (DBAP) has recently been proposed as a new technique for panning sound sources in two and three dimensional spaces spaces. In this paper, DBAP is compared with two established alternatives, Ambisonics and Vector-Based Amplitude Panning, both objectively in terms of speaker gains and their variation with source position, and subjectively using listening tests to ...

Cereals and soybeans are the main food sources for the majority of Chinese. This study evaluated the effects of four common cooking methods including steaming, boiling, frying, and milking on selenium (Se) content and speciation in seven selenium bio-fortified cereals and soybeans samples. The Se concentrations in the selected samples ranged from 0.91 to 110.8 mg/kg and selenomethionine (SeMet)...

We consider the problem of searching through visualizations of large amounts of data by performing panning and zooming operations. We give algorithms to travel from a source to an unknown target using a number of pans and zooms that is competitive with the optimal number of pans and zooms depending on certain parameters, and consider both the one-dimensional and two-dimensional versions of this...

BACKGROUND Galla Rhois has been considered to have medicinal properties against diarrhea, excessive sweating, bleeding, and chronic cough in Asian countries. Gallotannins, which are Galla Rhois-derived tannins, have been reported to possess biological and pharmacological activities, especially anticancer activity. In this study, we evaluated the effect of steaming at a temperature over 120 °C o...

BACKGROUND Panax ginseng Meyer is cultivated because of its medicinal effects on the immune system, blood pressure, and cancer. Major ginsenosides in fresh ginseng are converted to minor ginsenosides by structural changes such as hydrolysis and dehydration. The transformed ginsenosides are generally more bioavailable and bioactive than the primary ginsenosides. Therefore, in this study, hydroth...

A real-time semiautonomous stereo panning system for music mixing has been implemented. The system uses spectral decomposition, constraint rules, and cross-adaptive algorithms to perform real-time placement of sources in a stereo mix. A subjective evaluation test was devised to evaluate its quality against human panning. It was shown that the automatic panning technique performed better than a ...
