Most white blood cells (WBCs) recognition models present the disadvantages such as limited deployment due to large parameter count and computation amount, low WBC recognition accuracy, and poor generalization ability. Therefore, a lightweight and efficient WBCs recognition model based on improved EfficientNet is proposed. Firstly, the main modules are streamlined to reduce the model parameter count, while jump connections between feature layers are added to ensure a complete information flow. Secondly, the main module is optimized by adding the improved efficient channel attention and selecting a more suitable DropBlock2D. The improved module makes the model capture more channels and detail features, thus improving the recognition accuracy and generalization ability. Finally, the model is trained by a cross-entropy loss function with label smoothing to accelerate the convergence of the model and further enhance the generalization ability further. The experimental results show that the number of parameters of the improved model is 2.49M, which is 1.11M less than that before the improvement, simplifying the complexity of the model. The improved model achieves 99.67% accuracy in the classification task for the mixed dataset, which is 0.37% better than before the improvement. In addition, the model achieves 100.00% accuracy in the classification of the public dataset BCCD2, which is higher than the existing WBCs recognition models, verifying that the model has high accuracy and good generalization ability while maintaining lightweight computation.

BACKGROUND: Rare, dispersed, and rare earth elements are important strategic resources because of their special performance and function. At the same time, because of its unique geochemical properties, it is of great significance in the study of paleoclimate, paleo-water and paleo-sedimentary environment, and sediment sources. Previous studies have found that Ga in the Ningdong Coalfield is slightly enriched and rare earth element content is low. OBJECTIVES: To explore the possibility of enrichment and mineralization of rare, dispersed, and rare earth elements in the coal series of the Yan’an Formation of Middle Jurassic in the Ningdong Coalfield, and discuss the characteristics of paleosedimentary environment and properties of provenance rock. METHODS: Systematic sampling was carried out in the core of boreholes from the Lingwu and Jijiajing mining areas of the Ningdong Coalfield. ICP-MS was used to determine the content of rare, dispersed, and rare earth elements in mudstone, sandstone and top (bottom) plate of the Yan’an Formation. RESULTS: The overall content of rare, dispersed, and rare earth elements in the Yan’ an Formation of the Ningdong Coalfield is low, which do not meet the requirements of the industrial indicators of the deposit and cannot be exploited comprehensively. The highest content of Ga is 29. 40μg/ g, which is close to the lowest industrial grade of 30. 00μg/ g. Compared with the average content of elements in world coal, rare elements Li, Nb, Ta, Rb, Cs, Zr and dispersed elements Ga, In, Sc, Hf are slightly enriched or enriched. The distribution of rare earth elements shows LREY type, and significant negative anomaly of Eu. CONCLUSIONS: Rb, Sr and REY indicate the humidity of paleoclimate conditions, Li, Sr and Ga represent the freshwater deposition environment, and Ce, Ce/ La reflect the anoxic reducing environment. The REY content is not affected by diagenesis and can be used to discriminate the original sediment source. [ABSTRACT FROM AUTHOR]
