In this study, we describe the specific features of near-field distribution a uniformly illuminated aperture. An analytical method based on physical optics in time domain is used to calculate field intensity. The primitive impulse response function makes it possible antenna. difference amplitudes fields during observation point shift along X and Y coordinate axes can reach up 13% their maximum ...

The problem of a monopole mounted near the edge of a wedge or a vertex is considered. Three types of solutions-surface patch modeling, moment method/geometrical theory of diffraction (MM/GTD), and MM/eigenfunction-are presented, discussed, and compared with measurements. Results are in the form of input impedance and radiation patterns.

در این مقاله اثر صفحه زمین محدود آنتن بر الگوی تشعشعی آن تحلیل و بررسی شده است. الگوی تشعشعی چند نمونه آنتن تک قطبی سیمی ساده و یک آنتن تک قطبی خط پیچ دار تیغه ای شکل -که با المان های فشرده بارگذاری شده و پهنای باند 30-500 mhz را پوشش می دهد- با صفحه زمین های محدود با روش های تحلیلی تفرق هندسی (gtd) و جریان معادل لبه (eec) محاسبه شده اند. نتایج تحلیلی و شبیه سازی ها نشان می دهد که روش gtd در حا...
Circulating Tumor DNA: A Potential Novel Diagnostic Approach in Gestational Trophoblastic Neoplasia.
http://dx.doi.org/10.1016/j.ebiom.2016.01.013 2352-3964/Crown Copyright © 2016 Published by Elsevie Gestational trophoblastic diseases (GTD) are a group of disorders that originate from the trophoblast, which is the outer layer of the blastocyst that normally gives rise to the placenta and is the first tissue to differentiate from the developing embryos after implantation. The human chorionic g...
Masaharu Fukunaga, M.D. Department of Pathology, the Jikei University Daisan Hospital, Tokyo, Japan Hydatidiform moles With the increased use of ultrasound hydatidiform mole (HM) is being diagnosed at increasingly early stages of gestation. As villous edema is not fully developed, we cannot make a diagnosis of HM by macroscopic observation. Furthermore, microscopically the classic features of c...
Gestational trophoblastic disease is a spectrum of placental disorders ranging from benign molar pregnancies to the neoplastic conditions such as invasive mole and choriocarcinoma. These patients are identified early due to markedly elevated hCG levels and characteristic ultrasound findings. Uterine evacuation is the recommended treatment, while chemotherapy can be reserved for patients with re...
This paper discusses development of physics-based models for bistatic scattering. We generalize parametric equations for monostatic scattering mechanisms in a plane to achieve analogous bistatic approximations. Combination of these mechanisms, as separable azimuth and elevation components, allows 3-D modelling of six scattering primitives: sphere, tophat, trihedral, dihedral, cylinder, and flat...
