Despite its recognized strength in global optimization problems, the high number of objective function evaluations requested by the Particle Swarm Optimization (PSO) method severely limits its application when the computational cost of the objective function calculation is large, as in most actual engineering problems. In order to overcome this deficiency to enable the efficient use of the PSO ...

A simple enzymatic method for production of a wide variety of D-amino acids was developed by kinetic resolution of DL-amino acids using L-amino acid oxidase (L-AAO) with broad substrate specificity from Rhodococcus sp. AIU Z-35-1. The optimum pH of the L-AAO reaction was classified into three groups depending on the L-amino acids as substrate, and their respective activities between pH 5.5 and ...

Many speech features and models, including Deep Neural Networks (DNN), are used for classification tasks between healthy pathological with the Saarbruecken Voice Database (SVD). However, accuracy values of 80.71% phrases or 82.8% vowels /aiu/ highest reported audio samples in SVD when evaluation includes wide amount pathologies database, instead a selection some pathologies. This paper targets ...

Aspirin is the oldest non-steroidal anti-inflammatory drug (NSAID), and it sometimes causes asthma-like symptoms known as aspirin-exacerbated respiratory disease (AERD), which can be serious. Unwanted effects of aspirin (aspirin intolerance) are also observed in patients with food-dependent exercise-induced anaphylaxis, a type I allergy disease, and aspirin-induced urticaria (AIU). However the ...
