Crystals | Free Full-Text | The Limits of X-ray Diffraction …
X-ray diffraction theory allows the interpretation of experiments to build a structural model that fits the collected data. As with any experimental science, the observations are subject to uncertainty through the instrument and user limitations. Similarly, the theory can never be perfectly complete; it will have limits, and therefore the …

Comparison between the 10- and the 30-s-long Wingate
Background The 30-s-long Wingate Anaerobic Test (WAnT_30s) has some limitations in high-level athletes. A shorter version might be helpful for both clinical applications and performance assessment. The comparison between the traditional WAnT_30s and a shorter version has never been carried out yet in Paralympic athletes. …

The Power and Limitations of Kernel Learning
In the last few years we have seen remarkable progress in machine learning in large part due to neural networks trained on large data. While shallow methods, in particular methods based on positive definite kernels, show excellent results on smaller data sets, their performance suffers at large scale. It turns out that some of this lack of …
