Item type:Publication, Subcellular Protein Patterns Classification Using Extreme Gradient Boosting with Deep Transfer Learning as Feature Extractor(2024-01-01); Wacharawichanant, SiriratProteins are essential structural and functional components of human cells. Understanding and identifying proteins can provide valuable insights into their structure, function and role in human body. Subcellular proteins provide the expression that characterizes the many proteins and their conditions across cell types. This work proposed a classification model for subcellular protein patterns using XGBoost with transfer learning of CNN as the feature extractor. In the model training process, we used ResNet50, VGG16, Xception, and MobileNet as the pre-trained models based on the transfer learning technique to extract different features. The proposed model was used to classify subcellular proteins into 28 patterns. The XGBoost with ResNet50, VGG16, MobileNet, and Xception model achieved an accuracy level of 92.20% 92.77%, 91.63%, and 91.44%, respectively. The XGBoost with ResNet50, VGG16, MobileNet, and Xception model obtained an F1 score of 0.9179, 0.9233, 0.9131, and 0.9152, respectively. Considering the F1 score, All XGBoost with transfer learning of CNN models gave a high score. Therefore, all evaluation parameters clearly demonstrate the high performance of the subcellular protein pattern classification model. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Morphology and Properties of Poly(Lactic Acid) and Polybutylene Succinate and Ethylene-co-Methyl Acrylate-co-Glycidyl Methacrylate Ternary Blends(2023-01-01) ;Wacharawichanant, Sirirat ;Netphong, Patcharin ;Pipatbannakit, ThakoonThis work studied the morphological, mechanical, and thermal properties of poly(lactic acid) (PLA)/polybutylene succinate (PBS)/ethylene-co-methyl acrylate-co-glycidyl methacrylate (EMA-GMA) ternary blends. The polymer blends were prepared in an internal mixer and then molded into films by compression molding. The results showed that the PLA/PBS blends had immiscible morphology in which the PBS phase was dispersed in PLA matrix as spherical shape. The PBS droplet size increased with increasing PBS content. The fractured surface of PLA/PBS/EMA-GMA blends displayed more small crack of plastic deformations than that of PLA/PBS blends and the fracture behavior of PLA/PBA blends was changed to more ductile fracture when added with EMA-GMA. The addition of EMA-GMA in polymer blends improved the compatibility of two phases. The results of the mechanical properties showed that PBS and EMA-GMA addition improved the strain at break of PLA/PBS and PLA/PBS/EMA-GMA blends, respectively. The incorporation of EMA-GMA had no effect on the melting temperature and degradation temperature of PLA blends. The PLA/PBS/EMA-GMA blends had lower percent crystallinity than that of PLA/PBS blends and most of percent crystallinity decreased with increasing EMA-GMA loading due to its more amorphous structure than PLA and PBS.
