Use of a genetic algorithm - Neural network hybrid algorithm in the search for high efficiency solid-state phosphors

Artificial Intelligence methods have been employed in the search for solid-state phosphors with a high luminescence quantum yield. An Artificial Neural Network was used to investigate how luminescence efficiency can be linked to phosphor composition. The trained network was then coupled to a Genetic Algorithm whose role was to locate the global optimum composition in the search space. The compound Tb0.039Gd0.104Ce0.063Si0.401B0.393Od (where d indicates the stoichiometrically-required amount of oxygen) is estimated to be the optimum oxide composition that generates the highest green phosphor luminescence for use in tricolour white LEDs, when excited by a 400 nm light source

It’s Beyond Our Group ZPD : A Sociocultural Approach to the Unsuccessful Self-treatment of Writer’s Block in Times of COVID-19

This study is a replication of Upper (1974). Our results are identical. We too have been unable to focus and accomplish our writing goals since the beginning of the global pandemic. We are certainly not alone, and we would like to recognize all of our colleagues who have also had to take on additional responsibilities at work and at home over the past year that have made writing nearly impossible.nonPeerReviewe
