A Study on the Optimization of Optical Guide of Gamma Camera Detector

An optical guide, which is a light guide located between NaI(Tl) scintillation-crystal and array of photo-multiplier tubes (PMTs) in the gamma camera detector system, is an essential component to deliver the spatial information recorded in scintillator to the PMTs. Without the optical guide, the spatial information within the range of a single PMT could not be obtained. For the design of the op...

NONLOCAL s-MINIMAL SURFACES AND LAWSON CONES

Here 0 < s < 1, χ designates characteristic function, and the integral is understood in the principal value sense. The classical notion of minimal surface is recovered by letting s → 1. In this paper we exhibit the first concrete examples (beyond the plane) of nonlocal s−minimal surfaces. When s is close to 1, we first construct a connected embedded s-minimal surface of revolution in R, the non...

could find no other major social or environmental change that occurred in the population we served which mighthave explained these striking findings. We agree with Dr Platt that it would have been advantageous to compare our experience with that of similar districts in England. Despite strenuous efforts, however, we could not obtain comparable data of this type. The experience in the Edinburgh ...

Camera-Ready Paper Submission GUIDE

Considering the value of semiconductor IP (Intellectual Property), fundamental knowledge of legal protection for IP is essential requirement for both IP providers and IP users. Since IPs are recognized as one of the intangible assets, present intellectual property system, such as patent, copyright, trade secret, and mask work protection system should provide certain legal protection by their ow...
