Tunnel coupling is a key parameter in coupled semiconductor quantum dots, and crucial ingredient various device applications, such as exchange gates spin shuttling information processing. A widely used charge-sensing technique to extract the tunnel of double dot accounts for only ground orbital state each dot, but authors show that Si valley-orbit must be included analysis. With their more comp...
A phantom limb is the sensation that an amputated limb is still attached to the body and is moving together with other body parts. Phantom limb phenomenon is often described on the basis of the patient's subjective sense, for example as represented using a visual analog scale (VAS). The aim of this study was to propose a novel quantification method for behavioral aspect of phantom limb by psych...
Over the last decade, the R-tree has emerged as one of the most robust multidimensional access methods. However, before the R-tree can be integrated as an access method to a commercial strength database management system, eecient techniques to provide transactional access to data via R-trees need to be developed. Concurrent access to data through a multidi-mensional data structure introduces th...

Introduction Based on Task Group No. 43 (TG-43U1) recommendations, water phantom is proposed as a reference phantom for the dosimetry of brachytherapy sources. The experimental determination of TG-43 parameters is usually performed in water-equivalent solid phantoms. The purpose of this study was to determine the conversion factors for equalizing solid phantoms to water. Materials and Methods T...
This study evaluated a new body composition phantom and its use for quality control and cross-calibration of dual-energy X-ray absorptiometry (DXA) instruments for measurements of body composition. We imaged the variable composition phantom (Lunar, Madison, WI) on eight different DXA devices. Deviations of up to 7% fat were observed when we compared the percent fat values measured by the differ...
Amputees who have a phantom limb often report the ability to move this phantom voluntarily. In the literature, phantom limb movements are generally considered to reflect motor imagery rather than motor execution. The aim of this study was to investigate whether amputees distinguish between executing a movement of the phantom limb and imagining moving the missing limb. We examined the capacity o...
We modified the Imaging Performance Assessment of CT scanners (ImPACT) to evaluate the organ doses and the effective dose based on the International Commission on Radiological Protection (ICRP) Publication 110 reference male/female phantom with the Aquilion ONE ViSION Edition scanner. To select the new CT scanner, the measurement results of the CTDI100,c and CTDI100,p for the 160 (head) and the...
CuO, known to be multiferroic (MF) from ${T}_{L}\phantom{\rule{4pt}{0ex}}=\phantom{\rule{4pt}{0ex}}213\phantom{\rule{4pt}{0ex}}\mathrm{K}$ ${T}_{N}\phantom{\rule{4pt}{0ex}}=\phantom{\rule{4pt}{0ex}}230\phantom{\rule{4pt}{0ex}}\mathrm{K}$ at ambient pressure, has been the subject of debates about its ability exhibit multiferroicity room temperature (RT) under high hydrostatic pressure. Here we a...
