Once the algorithm is trained, it receives in input the exports of countries in a year y (not used during the training stage) and its output is the relatedness of countries with a product. Figure 9 Schematic diagram with the functioning of machine learning algorithms to assess the relatedness...
The research samples were randomly divided into training and testing sets at a ratio of 4:1, with rotation of the test dataset to implement 5-fold cross validation. The initial value of the hyperparameters used in this model was determined by parameter grid search, using 5-fold cross-...
Seminiferous tubules at stage VII showed a number of irregularities, including the formation of vacuoles and a smaller number of round spermatids arranged in irregular patterns (Figure 2F). In addition, multinucleated cells (arrows in Figure 2F), which appear to be abnormal round spermatids, were...

The lack of a reliable test for diagnosing early PDAC may account for the poor overall survival of patients with this disease, as they are usually diagnosed at an advanced stage due to a lack of or vague symptoms when the cancer is still localized [3]. Thus, it is critical to developing...
These metabolites were significantly increased or decreased on AAN progression from early stage to advanced stage. These metabolites could potentially serve as biomarkers for progressive AAN. (F) PCA score plot based on the five metabolites of the control group and AAN group. All statistical ...
2a). Notably, PRMT1 expression correlated with increased tumor size and higher grade, but not with lymph node status or TNM stage (Fig. 2b, Additional file 2: Table S1). Importantly, Kaplan–Meier survival analysis showed that CRC patients with high PRMT1 expression had shorter overall ...
s Exact test and identified 29 differentially represented genomic regions (see Additional file10). Second, we used the Survival Predictive Power tool of Nexus in order to determine gains and losses significantly correlated with poor survival in the subset of stage 2 and 3 primary CRCs producing a...
To test these hypotheses, we generated a signature of fifty metabolites that would distinguish between control animals and those carrying early stage lesions or the respective age-matched control animals and ones with late stage lesions. It was quite striking that the serum metabolic signature in ...
