Recently, a new kind of set, named Random Permutation Set (RPS), has been presented. RPS takes the permutation certain set into consideration, which can be regarded as an ordered extension evidence theory. Uncertainty is important feature RPS. A straightforward question how to measure uncertainty To address this issue, entropy (RPS entropy) presented in article. The proposed compatible with Deng and Shannon entropy. In addition, meets probability consistency, additivity, subadditivity....

This study developed a drug-loadable hydrogel system with high plasticity and favorable biological properties to enhance oral bone tissue regeneration. Hydrogels of different calcium alginate concentrations were prepared. Their swelling ratio, degradation time, bovine serum albumin (BSA) release rate measured. Human periodontal ligament cells (hPDLCs) marrow stromal (BMSCs) cultured both hydrogels polylactic acid (PLA), then we examined the proliferation cells. Inflammatory-related factor...
