Alveolar hydatid disease of the liver: Brief review and spectrum of adjacent organ invasion

Australasian Radiology, 2007
SummaryThe purpose of this study is to show the spectrum of adjacent organ invasion and to make a brief review of hepatic alveolar hydatid disease (AHD), using CT and MR imaging. We retrospectively reviewed CT and MR images of three patients with various adjacent organ invasions surgically and histologically proven to be AHD.

Nonlinear Spectrum-Spreading Interference Effects Between Adjacent Satellite Transponders

IEEE Transactions on Communications, 1975
For communications satellites carrying a phase-shift keying (PSK) modulated carrier in one transponder and FM carriers in neighboring transponders, there is a potential adjacent interference effect from the PSK carrier into the FM carriers. In this correspondence the noise-power ratio (NPR) degradation is calculated for the top voice channels of the FM

De-multiplexing the required spectrum in a traffic demand into multiple non-adjacent granular spectrums for dynamic traffic grooming in EON

Optical Switching and Networking, 2019
Abstract An elastic light-trail, the advanced version of a traditional light-trail, is one of the most recent dynamic traffic grooming technologies in an elastic optical network. In such networks, Orthogonal Frequency Division Multiplexing (OFDM) is a promising technology to execute the RSA (routing and spectrum assignment) algorithm and implement an

From the Spectrum of the Adjacency Matrix to the Spectrum of Directed Edge Matrix: Counting Cycles of a Bipartite Graph Through a Simple Equation

2019 IEEE Information Theory Workshop (ITW), 2019
Counting short cycles in bipartite graphs is a fundamental problem of interest in many fields including the analysis and design of low-density parity-check (LDPC) codes. There are two computational approaches to count short cycles (with length smaller than 2g, where g is the girth of the graph) in bipartite graphs. The first approach is applicable to a

Target adjacency influence estimation using ground spectrum measurement and Landsat-5 data

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
This paper addresses the adjacency effect estimation in ground spectrum and Landsat-5 pixels. The adjacency effect influences a pixel DN value by adding surface surrounding scatter signal and path scatter signals at sensor. Based on the theory of radiation transfer we designed a system that measuring the reflectance from the surface target material and
