The rewrite rule and cost model was implemented as SQL rewrite in Python, using statistics obtained from Trino (SHOW STATS) and SQL Server (DBCC SHOW_STATISTICS). Host Systems We tested the following host systems: • Trino (v373): a distributed SQL query engine with a NFA-based MATCH_...
A correlation coefficient ≥ 0.5 (p value ≤ 0.05) represents a close positive correlation, and a correlation coefficient ≤ − 0.5 (p value ≤ 0.05) represents a close negative correlation. The CDS of S. baicalensis was uploaded to the Kyoto Encyclopedia of Genes and ...
represents the correlation coefficient and its significance between the two variables, the lower left corner represents the scatter plot of the correlation between the two variables, and bar graph on the diagonal represents the distribution of the quantity of the corresponding variable, the curve repres...
where PCC is the Pearson correlation coefficient and RMSE is the root mean square error. Furthermore, some additional parameters, such as a learning rate of 0.001, decay constant of 1e−6, and momentum of 0.9, were kept constant during the learning. Rectified linear units (ReLUs) were used...
Weak but significant correlations were observed between DF and FSA at all speeds (r ≤ 0.48 andP < 0.001; Table3). Nonetheless, FSA was only able to explain ~ 20% of the variance of DF. The angle of the lower limb at initial ground contact relative to the vertical axis...
To investigate the correlation between RNA sequencing and real-time RT-PCR results, the Pearson correlation coefficient was calculated using non-transformed expression values for both methods. All samples that were RNA sequenced from the 13 patients in the DGEA were included, rendering a total of 48...
[26]. The value of MCC is from − 1 to + 1, where + 1 represents a perfect prediction, 0 an average random prediction and − 1 an inverse prediction. Hence, wwe also list the Matthews correlation coefficient (MCC) [26] (Eq. (4)) and Balanced Accuracy (Balance Acc....
In fact, Pearson correlation coefficients and p-values were calculated using python's “scipy.stats.pearsonr” function. The predicted target variable represents photovoltaic power, which is defined as Y. Base on the Conclusion In conclusion, a hybrid forecasting model (ALSM) is proposed through a...

We use python 2.7 plus numpy and scipy packages to conduct all the simulations. Results Definition of natural cities In order to define cities in a more natural and unified way, we explore the nighttime light images by varying the low light thresholds designating the spatial extent of contiguous...
