We experimentally demonstrated an enhanced translation of an x-ray beam nearly parallel to the diffracting planes over millimeter distances in a deformed silicon crystal. This effect is a consequence of the Berry-phase effect in phase space [K. Sawada, Phys. Rev. Lett. 96, 154802 (2006)], which enables an interplay between the gap in the dispersion surface in momentum space and the atomic displ...

Cis-Diamminedichloroplatinum II (CDDP) has been recognized as one of the most active drugs against malignant tumours including ovarian cancer. However, CDDP is a toxic drug causing emesis, renal failure, hearing loss, neuropathy and anaemia. In view of these toxicities many investigators have attempted to develop new platinum analogues which retain anti-tumour activity with less toxicity. Among...

Let Pt and C` denote a path on t vertices and a cycle on ` vertices, respectively. In this paper we study the k-coloring problem for (Pt, C`)-free graphs. Maffray and Morel, and Bruce, Hoang and Sawada, have proved that 3-colorability of P5-free graphs has a finite forbidden induced subgraphs characterization, while Hoang, Moore, Recoskie, Sawada, and Vatshelle have shown that k-colorability of...

Phospholipidosis (PLD) is characterized by an intracellular accumulation of phospholipids in lysosomes and the concurrent development of concentric lamellar bodies. Recently, H. Sawada et al. (2005, Toxicol. Sci. 83, 282-292) identified 17 genes as potential biomarkers of PLD in HepG2 cells. The present study was undertaken to determine if this set of genes measured by quantitative PCR could be...

We study how to generate binary de Bruijn sequences efficiently from the class of simple linear feedback shift registers with function $f(x_0, x_1, \ldots, x_{n-1}) = x_0 + x_1 x_{n-1}$ for $n \geq 3$, using cycle joining method. Based on properties this LFSRs, we propose two new generic successor rules, each which produces at least $2^{n-3}$ sequences. These classes build upon a framework prop...

The design optimization of a wing for supersonic transport by means of Multiobjective Genetic Algorithm (MOGA) is presented. The objective function is to minimize the drag for transonic cruise, the drag for supersonic cruise and the bending moment at the wing root for the supersonic condition. The wing shape is defined by planform, thickness distributions and warp shapes, in total of 66 design ...
