In order to find out the reason for the bogie frame instability alarm in the high-speed railway vehicle, the influence of wheel tread profile of the unstable vehicle was investigated.By means of wheel-rail contact analysis and dynamics simulation, the effect of tread wear on the bogie frame lateral stability was studied.The result indicates that th
This study compares four machine-learning algorithms comprising of Classification And Regression Trees (CART), Random Forest (RF), Gradient Tree Boosting (GTB) and Support Vector Machine (SVM) for the classification of urban land-use and land-cover (LULC) features.Using multitemporal and multisensor Landsat data from 1984-2020 at 5-year intervals f
Mycolactone, the amphiphilic macrolide toxin secreted by Mycobacterium ulcerans, plays a significant role in the pathology and manifestations of Buruli ulcer (BU).Consequently, it follows that the toxin is a suitable target for the development of diagnostics and therapeutics for this Heart Bracelet_Chloe disease.Yet, several challenges have deterre
The transformation of ownership, often reminiscent of the earlier historical period of the original accumulation of capital, is an opportunity for the rapid enrichment of those who MYRRH had a monopoly in former socialist societies.At the same time, the redistribution of national wealth encourages changes in the relationship of forces in the social
Pre-trained language models (LMs) have been shown to achieve outstanding performance in various natural language processing tasks; however, these models have a significantly large number of parameters to handle large-scale text corpora during the pre-training process, and thus, they entail the risk of overfitting when fine-tuning for small Garden t
