In this study, we investigated the impact of fluctuating water levels on the distribution of lead (Pb) and zinc (Zn) in soil and sediments at a historical Pb-Zn smelting site along the Xiangjiang River. Despite the high pH levels (7 to 11) in the study area, which generally inhibits heavy metal solubility, we found that regular changes in water levels still affect Pb-Zn movement. Soil analysis revealed distinct redox zones within the unconfined aquifer, as shown by the variable Fe/Mn and Ce/Ce* ratios.

Article Synopsis
  • Sequential recommendation seeks to suggest the best items for a user at a specific time based on their past behavior, but traditional methods often overlook how users influence each other.
  • The proposed framework incorporates dynamic user-item heterogeneous graphs to effectively model both user behaviors and inter-user influences, enhancing the recommendation process.
  • By using conditional probability estimation and conditional random fields for aggregating data, the method shows promising results on various datasets, highlighting its effectiveness in sequential recommendations.
