Nambu at Work

Abstract

This paper is based on a talk delivered on 16 November, 2015 in Osaka at the Nambu's Century: International Symposium on Yoichiro Nambu's Physics.Yoichiro Nambu, whose life and seminal contributions to Physics we celebrate here, went in 1952 to the Institute for Advanced Study in Princeton.Shortly after his arrival there, J. Robert Oppenheimer, the Institute's director, put Yoichiro and the other new arrivals on notice that though Albert Einstein was a professor at the Institute, and therefore had an office there, nobody was to disturb the great man without first receiving special permission personally from Oppie.Most people would spend a year or two in the same building with Einstein and then spend a whole lifetime regretting not to have met him. Yoichiro decided that he will meet Einstein, no matter what Oppie says. He knew Bruria Kaufmann, Einstein's assistant at that time, and with her help got to visit the great physicist. Einstein was very friendly and visibly happy that finally one of the young people had bothered to visit him. Einstein asked Yoichiro what was going on in particle physics, and was rather skeptical about separate nucleon and meson fields for which he saw no deeper reason.

Defect States-Related Photothermal Conversion of UV Photons in TiO2-Based Materials

“…13 N-doped TiO 2 samples with various N amounts were synthesized by heating the TiO 2 precursor in NH 3 atmosphere at various temperatures. 14,15 Three samples with increasing N amounts were prepared under 575, 625, and 700 °C and named as N-TiO 2 -1, -2, and -3, respectively.…”

The Application of Tree-based model to Unbalanced German Credit Data Analysis

“…In machine learning, an effective method to improve the performance and stability is ensemble learning [19]. Adaboost [11] is a representative ensemble learning algorithm, which combines the predictions of several trees with a weight sum to form the final prediction. In the training process, the weights of samples are updated according to those misclassified samples in previous training process.…”

“…Therefore, machine learning ensemble meta-algorithms are used to improve the stability and accuracy. Two representative machine learning ensemble meta-algorithms are Adaptive Boosting (AdaBoost) [11] and Bootstrap aggregating (Bagging) [12]. Adaptive Boosting is formulated by Yoav Freund and Robert Schapire.…”
