Purpose Capecitabine and S-1 are orally administered fluorinated pyrimidines with high-level activity against metastatic breast cancer (MBC). This randomized, multicenter, phase II study compared the activities and safeties of the oral fluoropyrimidines, capecitabine and S-1, in breast cancer patients. Methods Patients with MBC were randomly assigned to receive capecitabine 825 g/m2 twice daily...
AlGaN/GaN high electron mobility transistors (HEMTs) were improved for X-band and Ku-band applications. The power added efficiency (PAE) was achieved over 40% for X-band and over 30% for Ku-band. The developed devices combined two AlGaN/GaN HEMTs of 12 mm gate periphery and exhibited the output power of over 50 W. An AlGaN/GaN HEMT with four dies of 12 mm gate periphery was developed and exhibited...
The Voronoi game is a two-person game which is a model for competitive facility location. The game is played on a continuous domain, and only two special cases (the 1D case and the 1-round case) are well investigated. We introduce the discrete Voronoi game in which the game arena is given as a graph. We first show the best strategy when the game arena is a large complete k-ary tree. Next, we show...
