The current synthetic aperture radar (SAR) theory makes a quite restrictive assumption – linearity – in the SAR imaging model, for the convenience of mathematical derivation. That is to say the imaged area is considered as an ensemble of individual point scatterers whose scattered fields and, hence, their responses in the SAR image superimpose linearly [1]. This is the so called the first Born ...

(131)I-metaiodobenzylguanidine (MIBG) has been used as a therapeutic agent for pheochromocytoma. Tumor localization and precise staging are essential for therapy with high-dose (131)I-MIBG. The sites and extent of (123)I-MIBG uptake are usually estimated to predict the effectiveness of therapy before administration. However, conventional scintigraphic images provide insufficient anatomic inform...

Signal superimpose technique utilized in a micro-scale thermal imaging has been developed recently [1]. In this study the applicability of this technique to un-cooled micro-bolometer IR detector arrays is precisely examined. The method of pixel-by-pixel temperature calibration with superimposed temperature signal and a pseudo-acceleration of the sampling frame rate with a synchronized signal ar...

Data on the effect on mucociliary clearance of oral high frequency oscillation is conflicting. By means of a technique to superimpose high frequency oscillation on tidal breathing, changes in mucociliary clearance during high frequency oscillation were studied in seven normal non-smokers by monitoring the clearance of inhaled radiolabelled aerosol from the lungs. After inhalation of 5 microns t...

This study aimed to create Augmented Reality (AR) materials at understanding the scientific conceptions of electric current, devise teaching methods using created AR materials, and verify effectiveness through class-room practice. To achieve these objectives, this that superimpose current models on experimental apparatuses worksheets a tablet PC, devised method focuses clarifying students’ mis-...

Our laboratory previously reported (Anal Chem 55: 2345-2348, 1983) the development of a digitizer and FORTRAN program for display and quantification of digitized autoradiographic images. We have since added several capabilities to the program. Coarse "rubber sheeting" (i.e., transforming coordinates to superimpose images) of the image by a quadratic transformation of pixel coordinates is develo...

RNA molecules are attractive therapeutic targets because non-coding RNA molecules have increasingly been found to play key regulatory roles in the cell. Comparing and classifying RNA 3D structures yields unique insights into RNA evolution and function. With the rapid increase in the number of atomic-resolution RNA structures, it is crucial to have effective tools to classify RNA structures and ...

Augmented reality allows us to superimpose digital information upon the real world. In creative environments, this information can change as your ideas take shape. Storyboards allow designers to piece together different elements of a story and consider alternative storylines. The same board could be used to deliver additional experiences by overlaying other content types. Using Argon, an augmen...

The principle underlying SI-OSR is the formation of Moiré fringes that result when two patterns such as those shown in Fig.[1]-row1, superimpose multiplicatively. The patterns correspond to the unresolved spatial detail in the scene, and the Structured Illumination. Their product produces fringes at spatial frequencies that are significantly lower than those of the underlying patterns, and pote...

Körner and Marton established the capacity region for the 2-receiver broadcast channel with degraded message sets. Recent results and conjectures suggest that a straightforward extension of the Körner-Marton region to more than 2 receivers is optimal. This paper shows that this is not the case. We establish the capacity region for a class of 3-receiver broadcast channels with 2-degraded message...
