I have developed "tennis elbow" from lugging this book around the past four weeks, but it is worth the pain, the effort, and the aspirin. It is also worth the (relatively speaking) bargain price. Including appendixes, this book contains 894 pages of text. The entire panorama of the neural sciences is surveyed and examined, and it is comprehensive in its scope, from genomes to social behaviors. The editors explicitly state that the book is designed as "an introductory text for students of biology, behavior, and medicine," but it is hard to imagine any audience, interested in any fragment of neuroscience at any level of sophistication, that would not enjoy this book. The editors have done a masterful job of weaving together the biologic, the behavioral, and the clinical sciences into a single tapestry in which everyone from the molecular biologist to the practicing psychiatrist can find and appreciate his or

IEEE Standard for Local and Metropolitan Area Networks Part 16: Air Interface for Fixed Broadband Wireless Access Systems Draft Amendment: Management Information Base Extensions

The objective of this study was to develop anatomically correct whole body human models of an adult male (34 years old), an adult female (26 years old) and two children (an 11-year-old girl and a six-year-old boy) for the optimized evaluation of electromagnetic exposure. These four models are referred to as the Virtual Family. They are based on high resolution magnetic resonance (MR) images of healthy volunteers. More than 80 different tissue types were distinguished during the segmentation. To improve the accuracy and the effectiveness of the segmentation, a novel semi-automated tool was used to analyze and segment the data. All tissues and organs were reconstructed as three-dimensional (3D) unstructured triangulated surface objects, yielding high precision images of individual features of the body. This greatly enhances the meshing flexibility and the accuracy with respect to thin tissue layers and small organs in comparison with the traditional voxel-based representation of anatomical models. Conformal computational techniques were also applied. The techniques and tools developed in this study can be used to more effectively develop future models and further improve the accuracy of the models for various applications. For research purposes, the four models are provided for free to the scientific community.

Introduction to Electromagnetic Compatibility

It is well known that electromagnetic (EM) energy is absorbed inhomogeneously in the human body even for plane-wave exposure. This implies that local resonance for various individual organs may occur. In order to investigate this implication, we analyzed numerically the organ resonance characteristics in the frequency range from 30 MHz up to 3 GHz with an anatomically based high-precision human body model and a parallel finite-difference time-domain (FDTD) technique. As a result, we found that the whole-body resonance occurring around 65 MHz causes the local resonance for all the organs at the same frequency. Local resonance peculiar to each of organs was also found to occur around 900 GHz for the brain, eyes and heart, 600 MHz for the testicles, and so on.

FDTD calculation of organ resonance characteristics in an anatomically based human model for plane-wave exposure

In compliance assessments of radio-frequency exposure from cellular-phone-base station antennas, the root of 6-min time average of the squared electric fields is commonly required. Under the assumption that the time-varying electric fields belong to an ergodic process, a new approach has been proposed to estimate the 6-min time average from the ensemble average of the squared electric fields based on amplitude probability distribution (APD) measurements for a shorter time, much less than 6 min. The usefulness of the approach has been demonstrated at the 800-MHz band and the 1.5-GHz band, and the results have shown that by using a fast sampling rate, 1-min APD measurements could give a good estimate of the 6-min time average with an accuracy of within 10%.

Amplitude Probability Distribution Measurement for Electric Field Intensity Assessment of Cellular-Phone-Base Stations

This paper evaluates the performance of an equal gain combining (EGC) diversity receiver for implant body area networks (BANs) at 400 MHz medical implant communication service (MICS) band. To begin with, in order to analyze the performance of the EGC diversity receiver, we perform finite-difference time-domain (FDTD) simulations on implant BAN propagation with a numerical human model, and investigate the propagation characteristics of implant BAN signals. Then, this paper presents an EGC diversity system for implant BANs which can improve the communication performance and evaluates the bit error rate (BER) performance by theoretical analysis. In the theoretical analysis, it is difficult to analytically derive the probability density function (pdf) on the combined signal-to-noise power ratio (SNR) at the EGC receiver output. Therefore, we introduce two approximation methods such as the moment generating function (MGF) method and the curve fitting method. The paper demonstrates that the performances by the theoretical analyses with the two approximation methods are almost corresponding to those by the computer simulations.
