Double Bundle Method for Nonsmooth DC Optimization

The aim of this paper is to introduce a new proximal double bundle method for unconstrained nonsmooth DC optimization, where the objective function is presented as a difference of two convex (DC) functions. The novelty in our method is a new stopping procedure guaranteeing Clarke stationarity for solutions by utilizing only DC components of the objective function. This optimality condition is s...

The Importance of Examining Congenital Hypothyroidism in Connection with Congenital Heart Disease: Letter to Editor

Dear Editor-in-Chief: I read and enjoyed your stylish article, "Frequency of Congenital Cardiac Malformations in Neonates with Congenital Hypothyroidism", in relation to heart disease with hypothyroidism. As we know, one of the most commonly associated congenital hypothyroidism disorders is congenital heart disease, which has a significant effect on the recovery of pat...

Serum metabolomic analysis of pancreatic cancer--letter.

In their recent article, Kobayashi and colleagues (1) sought to construct and validate a diagnostic model for pancreatic cancer using gas chromatography-mass spectrometry-based human serum metabolomics approach. The study included a training set (n1⁄4 85) and a validation set (n 1⁄4 106). Using a multiple logistic regression analysis, the authors established a diagnostic model including 4 varia...
