LITHOLOGICAL CLASSIFICATION BY HYPERSPECTRAL IMAGES BASED ON A TWO-LAYER XGBOOST MODEL, COMBINED WITH A GREEDY ALGORITHM

Lithological Classification by Hyperspectral Images Based on a Two-Layer XGBoost Model, Combined with a Greedy Algorithm

Lithology classification is important in mineral resource exploration, engineering geological exploration, and disaster monitoring.Traditional laboratory methods for the qualitative analysis of rocks are limited by sampling conditions and analytical techniques, resulting in high costs, low efficiency, and the inability to quickly obtain large-scale

Evaluation of toxicity, local biocompatibility, biodegradation, and systemic metabolism of cellulose/alginate/strontium apatite membranes implanted subcutaneously in mice

ABSTRACT Purpose: To evaluate membranes originating from pure or oxidized bacterial cellulose (BC)/alginate/strontium apatite hydrogels regarding toxicity, biocompatibility, biodegradation and metabolism.Methods: The toxicity was measured by incubating the materials with Artemia salina for 24 h, and mortality and the 50% lethal concentration were d
