A deep learning-based approach for emotional analysis of sports dance.

There is a phenomenon of attaching importance to technique and neglecting emotion in the training of sports dance (SP), which leads to the lack of integration between movement and emotion and seriously affects the training effect. Therefore, this article uses the Kinect 3D sensor to collect the video information of SP performers and obtains the pose estimation of SP performers by extracting the key feature points. The Arousal-Valence (AV) emotion model, based on the Fusion Neural Network model (FUSNN), is also combined with theoretical knowledge.

Fe(II) oxygenation inhibits bacterial Mn(II) oxidation by P. putida MnB1 in groundwater under O-perturbed conditions.

Bacterial Mn(II) oxidation plays a crucial role in Mn cycling and the associated biogeochemistry in natural waters and is of practical concern in the clean-up of excess Mn from drinking water. Fe(II) usually occurring together with Mn(II) in groundwater is oxidized prior to Mn(II) when perturbed by O, but the impact of Fe(II) oxygenation on the subsequent bacterial Mn(II) oxidation remains unknown. Here we demonstrated that Fe(II) oxygenation largely inhibited the Mn(II)-oxidizing ability of MnB1 belong to Pseudomonas putida which is ubiquitous in groundwater.

Fluorescent component and complexation mechanism of extracellular polymeric substances during dye wastewater biotreatment by anaerobic granular sludge.

In this study, methylene blue (MB) wastewater was biotreated by anaerobic granular sludge (AnGS), and the fluorescent components of extracellular polymeric substances (EPS) and complexation mechanism were evaluated. Based on the experimental data, the sorption of MB by both live and inactivated AnGS followed the pseudo-second-order model, and the adsorption isotherm conformed well to the Langmuir model. It was shown that the difference in the sorption of live and inactivated AnGS was not significant, indicating that the sorption is mainly a physical-chemical process and metabolically mediated diffusion is negligible.
