Cortical Deficits In Schizophrenia : From Genes to Function
Opens with a chapter by Paul Harrison highlighting the several convergence points among the diverse schizophrenia-related genes. This is followed by chapters reviewing several different specific genes, including Neuregulin, DISC-1, dysbindin, and Homer, among others, and by several chapters presenting information on physiological cortical processes that could be affected by those genes. These include glutamatergic, GABAergic and cholinergic neurotransmission.Current hot topics in schizophrenia research are also highlighted in the book. A concept that is gaining strength in the field, the chapters in this book summarize the current state of affairs in schizophrenia pathophysiology, with a consideration of genetic elements that may contribute to it. Cortical Deficits in Schizophrenia: From Genes to Function will prove a useful tool for those interested in a better understanding of schizophrenia. Even if more predisposing genes (not included in this book) become identified, the work laid out here will prove critical for assigning a functional (or dysfunctional) role to those genes. Although this is a fast-evolving field, the information and concepts covered in this book will likely be useful for years to come.
Coordinated Multiuser Communications
Many communications systems, such as cellular mobile radio and wireless local area networks, are subject to multiple-access interference, caused by a multitude of users sharing a common transmission medium. The performance of receiver systems in such cases can be greatly improved by the application of joint detection and decoding methods. Multiuser detection and decoding not only improve system reliability and capacity, they also simplify the problem of resource allocation. Emphasis is placed on practical implementation aspects and modern iterative processing techniques for systems both with, and without integrated error control coding.

Continuous-Time Signals
The book systematically covers major principle foundations of the signals theory. The representation of signals in the frequency domain (by Fourier transform) is considered with strong emphasis on how the spectral density of a single waveform becomes that of its burst and then the spectrum of its train. Different kinds of amplitude and angular modulations are analyzed noticing a consistency between the spectra of modulating and modulated signals. The energy and power presentation of signals is given along with their correlation properties. Finally, presenting the bandlimited and analytic signals, the book elucidates the methods of their description, transformation (by Hilbert transform), and sampling.
Congenital infections : Toxoplasmosis and rubella
Torch syndrome is caused by a uterine infection with one of the factors that cause Torch syndrome, which disrupts the development of the fetus. Torch syndrome can be prevented by treating the infected pregnant woman, and thus preventing transmission of the infection to the fetus. And some of the factors that cause Torch Syndrome can give the mother permanent immunity, preventing the arrival of the disease and thus fetal malformations. They include a group of symptoms caused by a congenital infection such as toxoplasmosis, rubella, CMV and herpes, or due to other organisms such as syphilis, small viruses, and varicella zoster virus. The Toxoplasma parasite and the rubella virus can provide lasting immunity if the mother was infected before pregnancy in both or if she was vaccinated before pregnancy in Rubella.
Coherent sources of XUV radiation : Soft X-ray lasers and high-order harmonic generation
Extreme ultraviolet radiation, also referred to as soft X-rays or XUV, offers very special optical properties. The X-UV refractive index of matter is such that normal reflection cannot take place on polished surfaces whereas beam transmission through one micrometer of almost all materials reduces to zero. Therefore, it has long been a difficult task to imagine and to implement devices designed for complex optics experiments in this wavelength range. Thanks to new sources of coherent radiation - XUV-lasers and High Order Harmonics - the use of XUV radiation, for interferometry, holography, diffractive optics, non-linear radiation-matter interaction, time-resolved study of fast and ultrafast phenomena and many other applications, including medical sciences, is ubiquitous.

Cloud Optics
Clouds affect the climate of the Earth, and they are an important factor in the weather. Therefore, their radiative properties must be understood in great detail. This book summarizes current knowledge on cloud optical properties, for example their ability to absorb, transmit, and reflect light, which depends on the clouds’ geometrical and microphysical characteristics such as sizes of droplets and crystals, their shapes, and structures. In addition, problems related to the image transfer through clouds and cloud remote sensing are addressed in this book in great detail. This book can be an important source of information on theoretical cloud optics for cloud physicists, meteorologists and optical engineers.
Materials Fundamentals of Gate Dielectrics
This book presents materials fundamentals of novel gate dielectrics that are being introduced into semiconductor manufacturing to ensure the continuous scalling of the CMOS devices. This is a very fast evolving field of research so we choose to focus on the basic understanding of the structure, thermodunamics, and electronic properties of these materials that determine their performance in device applications. Most of these materials are transition metal oxides. Ironically, the d-orbitals responsible for the high dielectric constant cause sever integration difficulties thus intrinsically limiting high-k dielectrics. Though new in the electronics industry many of these materials are wel known in the field of ceramics, and we describe this unique connection. The complexity of the structure-property relations in TM oxides makes the use of the state of the art first-principles calculations necessary. Several chapters give a detailed description of the modern theory of polarization, and heterojunction band discontinuity within the framework of the density functional theory. Experimental methods include oxide melt solution calorimetry and differential scanning calorimetry, Raman scattering and other optical characterization techniques, transmission electron microscopy, and x-ray photoelectron spectroscopy.
Mapping Sustainability : Knowledge e-Networking and the Value Chain
Our underlying objectives are to contribute to the provision, mana- ment, and sharing of knowledge, and to enhance the value of knowledge and its uses by different constituencies in diverse contexts and at different stages of development. The central theme of this book, connecting its different parts, is about ways of transcending critical barriers to the effective uses of knowledge and e-networking. Of special relevance is the development of new approaches to the provision and transmission – from local sources to global networks and from global sources to local networks. In many ways, this is a book of theory and methods, as well as policy and performance.
Malaria disease and modern treatments
Some population groups are at considerably higher risk of contracting malaria and developing severe disease: infants, children under 5 years of age, pregnant women and patients with HIV/AIDS, as well as people with low immunity moving to areas with intense malaria transmission such as migrant workers, mobile populations and travellers. Malaria is an acute febrile illness caused by Plasmodium parasites, which are spread to people through the bites of infected female Anopheles mosquitoes. There are 5 parasite species that cause malaria in humans, and 2 of these species – P. falciparum and P. vivax – pose the greatest threat. P. falciparum is the deadliest malaria parasite and the most prevalent on the African continent. P. vivax is the dominant malaria parasite in most countries outside of sub-Saharan Africa.
