For practical application, the functional piezoelectric film in microelectromechanical systems should meet the requirement of physical properties, as well as the mechanical properties. In this article, 0.5Ba(Ti0.8Zr0.2)O3-0.5(Ba0.7Ca0.3)TiO3 (0.5BZT-0.5BCT) thin films with varied properties were prepared on (100) Si substrates via a sol-gel technique at… (More)

We retrospectively assessed the survival benefit of novel anticancer agents (NACA) after volume-reduction surgery for far-advanced gastric cancer (FAGC). From 1995 to 2005, 41 patients with FAGC underwent chemotherapy after volume-reduction surgery. Those treated since 2000 who received NACA were referred to as group A, and those treated before 2000, who… (More)

Two finite-difference methods for, geophysical .fluid problems are described, and stability conditions of these schemes arc discussed. These two schemes are formulated based upon a similar procedure given by Lax and Wendroff in order to obtain a second-order accuracy in finite-difference equations. However, the two schemes show remarkable differcnces.io… (More)

The system of equations describing the motion of a barotropic fluid with a free surface is solved by using finitedifference methods which are based on the two-step Lax-Wendroff scheme proposed by Richtmyer. The model has rigid boundaries along two latitude circles and the beta-plane approximation is adopted. Initial conditions are given for an ageostrophic… (More)

The motions of the atmosphere are governed by physical laws which are expressed in the form of the equations of hydrodynamics and thermodynamics. These equations are, in principle, well known, but some of the physical processes in the atmosphere, such as small-scale turbulence and convection, cloud formation, and precipitation mechanisms, are still… (More)

To improve the quality of horizontal divergence and moisture analyses in the tropics, adiabatic initialization scheme is developed to incorporate information on convective activity and the proxy data of precipitation obtained rrom satellite radiome:ric imagery data. The tropical precipitation rates are estimated by rleveloping a relationship lletwe:en the… (More)
