a time-domain approach is presented to calculate electromagnetic fields inside a large electromagnetic pulse (emp) simulator. this type of emp simulator is used for studying the effect of electromagnetic pulses on electrical apparatus in various structures such as vehicles, a reoplanes, etc. the simulator consists of three planar transmission lines. to solve the problem, we first model the meta...

An electromagnetic pulse (EMP) explodes in real-time and causes critical damage within a short period to not only electric devices, but also to national infrastructures. In terms of EMP shielding rooms, metal plate has been used due to its excellent shielding effectiveness (SE). However, it has difficulties in manufacturing, as the fabrication of welded parts of metal plates and the cost of con...

Extramedullary plasmacytoma (EMP) is a rare variant of plasma cell myeloma that affects soft tissues. The head and neck region are the most affected sites, although others have also been described. Herein we report an uncommon case of EMP of the larynx in a 65-year-old male who presented with a history of progressive dysphonia and hoarseness. Laryngeal fiberscopy evidenced a reddish pedicled vo...

a r t i c l e i n f o Electronic Marketplaces (EMPs) are virtual intermediaries that facilitate exchanges of products between buying and selling organizations. Prior research has examined factors that explain the establishment of EMPs, but scant knowledge exists on how to determine their performance. This study draws on organizational theory to measure EMP performance, thereby utilizing the con...

Extramedullary plasmacytoma (EPM) is a plasma cell tumor arising outside of the bone marrow. Solitary EMP is an uncommon neoplasm and rarely occurs in the retroperitoneum and lacks distinctive clinical manifestations. We report a 26-year-old man with a solitary EMP in the retroperitoneum and discuss its clinical features, diagnosis and treatment.

BACKGROUND Computed tomography (CT) phenotypic characterization helps in understanding the clinical diversity of chronic obstructive pulmonary disease (COPD) patients, but its clinical relevance and its relationship with functional features are not clarified. Volumetric capnography (VC) uses the principle of gas washout and analyzes the pattern of CO2 elimination as a function of expired volume...

We calculate nucleosynthesis in Population (Pop) III supernovae (SNe) and compare the yields with various abundance pattern of extremely metal-poor (EMP) stars. We assume that the observed EMP stars are the second generation stars, which have the metal-abundance pattern of the Pop III SNe. Previous theoretical yields and observations do not match well. In this paper we consider high energy expl...

A new and improved model of red sprites is presented. Emphasis is placed on accounting for the puzzling observation of the spatial structure in the exnissions. The model relies on the electromagnetic pulse (EMP) fields created by a horizontal lightning discharge and includes the observed fractal structure of such discharges in the computation of the EMP power density. It, is shown that the mode...

Purpose: This paper aims to propose a new method of quantifying the scientific impact based on the Eigenfactor. Materials and Methods: We propose four scores, all based on a common parameter, called Emp: (1) article median score (AEmp) computed by summing the Emps for all articles published by a researcher, (2) AEmp Main, which only includes the articles published as a main author by a specific...

Hematol Oncol Stem Cell Ther 1(4) October 2008 hemoncstem.edmgr.com 241 Monoclonal extramedullary plasmacytoma (EMP) is a rare plasma cell tumor. The dil agnosis is based on a mass of clonal plasma cells separate from bone or bone marrow without evil dence of occult disease elsewhere. It occurs in the upper aerodigestive tract in more than 80% of patients, most often in the nasal cavity, parana...
