— The purpose of this study is to estimate the Electromagnetic Field (EMF) distributions excited by Cellular Radios in environments which are almost completely surrounded by conductive surfaces. Some examples of these types of environments are train carriages, elevators and airplanes. Since portable radios may be used in various environments, accurate and(More)
Japanese gentians (Gentiana triflora and Gentiana scabra) are amongst the most popular floricultural plants in Japan. However, genomic resources for Japanese gentians have not yet been developed, mainly because of the heterozygous genome structure conserved by outcrossing, the long juvenile period, and limited knowledge about the inheritance of important(More)
We developed molecular markers for discrimination of white and blue flower color in Japanese gentian plants. White-flowered gentians can be classified into two types, based on genetic and physiological features. One type includes four allelic variations (gtmyb3-1, gtmyb3-2, gtmyb3-3, and gtmyb3-4) of an anthocyanin biosynthetic regulator gene (GtMYB3),(More)
A numerical assessment methodology to understand the EMI imposed by magnetic resonance type wireless power transfer systems on active implantable medical devices (implantable cardiac pacemaker/cardioverter defibrillator) is introduced. A numerical estimation model that consists of magnetic resonant coils and a human torso phantom with a pacemaker model is(More)
Electromagnetic field (EMF) distributions created by a 5.2 GHz wireless transmitter inside train cars are analyzed and propagation characteristics are determined from the analysis results. We use the FDTD technique and a large-scale parallel computing technique to precisely estimate the EMF distributions inside cars with passengers.
SUMMARY The aim of this study is to develop a new whole-body averaged specific absorption rate (SAR) estimation method based on the external-cylindrical field scanning technique. This technique is adopted with the goal of simplifying the dosimetry estimation of human phantoms that have different postures or sizes. An experimental scaled model system is(More)
