We extracted the differential entropy (DE) features based on EEG signals and converted DE features into EEG topographic maps (ETM). Next, the ETM and facial expressions were fused by the multichannel ...

Consequently, the normalized difference vegetation index (NDVI) of the shadow areas is much lower than that of sunlit areas—a phenomenon known as the NDVI topographic shadow effect. In this study, we ...

OBJECTIVE: To investigate the morphometric and topographic aspects of coronary ostia, correlating them with the aortic leaflets. METHODS: Fifty-one hearts with the great vessels attached were analyzed ...
