Adequate removal of the previous filling material may be pivotal to a favorable outcome root canal retreatment teeth with post-treatment periodontitis in order permit access irrigants and medicaments persistent bacteria. However, even recent technological advances, including introduction specially designed instruments, no technique has been shown predictably promote complete removal. Supplement...

Variable importance, interaction measures, and partial dependence plots are important summaries in the interpretation of statistical machine learning models. In this article, we describe new visualization techniques for exploring these model summaries. We construct heatmap graph-based displays showing variable importance jointly, which carefully designed to highlight aspects fit. a matrix-type ...

A description of an approach to primary local image recognition is given. The motivation for its application and its characteristics are discussed. Then a method for correction of misclassifications that occur in primary local image recognition is proposed. This method uses a graph-based estimation technique that uses information contained in supplementary classes in order to remove misclassifi...

The creation of magnetic states that have long lifetimes has been the subject of intense investigation, in part because of their potential to survive the time taken to travel from the point of injection in a patient to the point where a clinically diagnostic MRI trace is collected. We show here that it is possible to harness the signal amplification by reversible exchange (SABRE) process to cre...

The short lived pincer complex [(C5H3N(CH2P((t)Bu)2)2)Ir(H)2(py)]BF4 is shown to be active for signal amplification by reversible exchange. This catalyst formulation enables the efficient transfer of polarization from parahydrogen to be placed into just a single molecule of the hyperpolarisation target, pyridine. When the catalysts (1)H nuclei are replaced by (2)H, increased levels of substrate...

In this study, the performance of supplementary stabilizer for static synchronous compensator (STATCOM) tuned based on particle swarm optimization method in order to improvement of dynamic stability is studied. Since STATCOM is usually used for damping Low Frequency Oscillations (LFO), a supplementary stabilizer is incorporated with STATCOM to reach the mentioned purpose. As a heuristic optimiz...

In this study, the performance of supplementary stabilizer for static synchronous compensator (STATCOM) tuned based on simulated annealing in order to improvement of dynamic stability is studied. Since STATCOM is usually used for damping Low Frequency Oscillations (LFO), a supplementary stabilizer is incorporated with STATCOM to reach the mentioned purpose. Simulated Annealing (SA) as a heurist...
