Stepped-frequency radar sensors are attractive for various surface and subsurface sensing applications. Stepped-frequency systems transmit consecutive trains of continuous-wave signals at different frequencies that are separated by a fixed amount. The unique characteristic of stepped-frequency systems is, although they work as frequency-based systems, their final response is described in a …
This volume provides an overview of (1) the physical and chemical foundations of dating methods and (2) the applications of dating methods in the geological sciences, biology, and archaeology, in almost 200 articles from over 200 international authors. It will serve as the most comprehensive treatise on widely accepted dating methods in the earth sciences and related fields. No other volume has…
Nanotechnology has already demonstrated surprising potential for improving the performance of construction materials and many of these recent developments were facilitated by NICOM symposia. The NICOM5 proceedings will cover the emerging opportunities and future use of nanotechnology in construction and will illustrate the broad potential for application of nanotechnology to challenging problem…
All animals, including humans, derive from a single cell, which possesses all the genetic instructions needed to define how the animal will look like. However, during development, the millions of cells that derive from the zygote will only select part of this genetic information to give rise to the various organs of the body. The coordination of different cell behaviours during development resu…
It is my great honor to be invited by Professor Zhu Chen as the chief editor of the Stem Cell Fascicle of Published Engineering. Chinese scientists have been devoting to the basic research and clinical application in the field of stem cell biology and have obtained a series of original achievement in the flow of exploration of fundamental theory, key scientific problem research, clinical tri…
The Encyclopedia of Science Education provides a comprehensive international reference work covering the range of methodologies, perspectives, foci, and cultures of this field of inquiry, and to do so via contributions from leading researchers from around the globe. Because of the frequent ways in which scholarship in science education has led to developments in other curriculum areas, the ency…
This book deals with the theoretical and computational simulation of monoperiodic nanostructures for different classes of inorganic substances. These simulations are related to their synthesis and experimental studies. A theoretical formalism is developed to describe 1D nanostructures with symmetric shapes and morphologies. Three types of models are considered for this aim: (i) nanotubes (rolle…
Psychopharmacology is the study of the effects of psychoactive drugs on the functioning of the central nervous system at all levels of analysis, thus embracing cognition, behavior, psychological states, neurophysiology, neurochemistry, gene expression, and molecular biology. It includes, as an integral part of its domain, the interaction of environmental and genetic factors with psychoactive dr…
Information Reuse and Integration addresses the efficient extension and creation of knowledge through the exploitation of Kolmogorov complexity in the extraction and application of domain symmetry. Knowledge, which seems to be novel, can more often than not be recast as the image of a sequence of transformations, which yield symmetric knowledge. When the size of those transformations and/or the…
It remains unclear when and where Charles Darwin had his transformative idea of species evolution through random variation and selective retention. The legend goes that the fi rst inklings of the idea came to him on board the Beagle during the ship’s visit to the Galapagos Islands in the Eastern Pacifi c. Here he beheld fi nches with differently shaped beaks, which suggested local adaptat…
