What kind of emotional experience does the application of digital technology in museums create for museum visitors? Can it be measured accurately and in real-time? What are its characteristics? This paper utilizes EEG signals and the PAD emotional model as research methods to conduct real-time digital measurement of visitors' emotional experiences at Tianyi Pavilion Museum in Ningbo City, focusing on their physiological and psychological reactions.The results show that: (1) In a quasi-experimental environment, linear SVM, polynomial kernel SVM, and Gaussian kernel SVM can all accurately classify the emotional tendencies of museum visitors with success rate of over 72%. (2) In a quasi-experimental environment, it is feasible and reliable to measure the immediate digital emotional experiences of visitors using EEG signals and the PAD emotion model.

- Scientists found that a small molecule called fulvic acid (FA) can help preserve cells when freezing them, making it easier to store them without forming ice that can ruin them.
- FA works by keeping ice from growing too much during freezing and helping it melt better when thawing, which is super important for saving cells like red blood cells.
- This discovery shows that FA can be better than some traditional methods for protecting blood cells, and it sticks to water and cell membranes, which might help keep the cells safe during the freezing process.
