Next-Generation FTTH Passive Optical Networks : Research Towards Unlimited Bandwidth Access
Dense FTTH Passive Optical Networks (PONs) is a cost efficient way to build fibre access, and international standards (G/E-PON) have been already launched, leading to new set of telecom products for mass deployment. However, these systems only make use of less than 1% of the optical bandwidth; thus, relevant research is taking place to maximize the capacity of these systems, with the latest opto-electronic technologies, demonstrating that the huge bandwidth available through the fibre access can be exploited in a cost efficient and reliable manner.
New Technologies, Mobility and Security
NTMS’2007 is the first IFIP International Conference on New Technologies, Mobility and Security that was held from May 2 to May 4, 2007 in Paris, France. NTMS'2007 aims at fostering advances in the areas of New Technologies, Wireless Networks, Mobile Computing, Ad hoc and Ambient Networks, QoS, Network Security and E-commerce, to mention a few, and provides a dynamic forum for researchers, students and professionals to present their state-of-the-art research and development in these interesting areas. The event was combined with tutorial sessions and workshops. Tutorials preceded the main program, aiming at the dissemination of mature knowledge and technology advances in the field. One Workshop immediately followed the main conference, offering the opportunity for a more focused exchange of ideas and presentation of on-going research relevant to selected topics.
New Perspectives on Aloe
The contents include a brief introduction of aloe, isolation, purification, and structural analysis of components, and various physiological effects of those components for possible use as health foods or drugs. Various functions identified were wound healing, angiogenesis, anti-allergy, skin whitening, stimulation of cell proliferation such as liver or kidney, protection against nephrotoxicity, and immune modulation. Moreover, we suggest standardization and quality control procedures for manufacturing raw aloe, and how to develop related products for successful application of aloe. This is important in Korea because last year the Korean government listed aloe as a health food for which the government establishes regulatory laws. Therefore, many scientists in Korea who are interested in studying health foods would be interested in this kind of text. Other major fields related to this kind of research will be medicine, biology, pharmaceutics, natural products and analytics.
Neuroactive Steroids in Brain Function, Behavior and Neuropsychiatric Disorders : Novel Strategies for Research and Treatment
Over the past few decades the involvement of neurosteroids in brain function and mental health has attracted much interest, not only from a neuroscience perspective, but also from clinical and therapeutic aspects. In recent years, much of the research has focused on the multifunctional position of neurosteroids in the nervous system. The areas that have been explored, in particular, are the cellular and molecular mechanisms involved in the activity of neurosteroids in the brain, the role of neurosteroids in brain development, neurodegeneration and neuroplasticity, and their pharmacological properties. The large increase in the number of publications highlights this amplified interest in neurosteroids. Over the last 7 years at least 400 papers have been published describing the putative role of neurosteroids in the modulation of basic brain function and in the etiology and treatment of psychiatric and neurological disorders.

Multi-Carrier Spread Spectrum 2007 ; Proceedings from the 6th International Workshop on Multi-Carrier Spread Spectrum, May 2007,Herrsching, Germany
This combination known as multi-carrier spread spectrum (MC-SS) benefits from the advantages of both systems and offers high flexibility, high spectral efficiency, simple detection strategies, narrow-band interference rejection capabilities, etc. The basic principle of this combination is straightforward: The spreading is performed as direct sequence spread spectrum (DS-SS) but instead of transmitting the chips over a single carrier, several sub-carriers are employed. The MC modulation and demodulation can easily be realized in the digital domain by performing IFFT and FFT operations. The separation of the users’ signals can be performed in the code domain. MC-SS systems can perform the spreading in frequency direction, which allows for simple signal detection strategies. Since 1993, MC-SS has been deeply studied and new alternative solutions have been proposed.
Monoaminergic modulation of cortical excitability
Monoaminergic Modulation of Cortical Excitability serves as an integrative and comprehensive comparison of the diverse and complex modulatory action of dopamine, noradrenaline, and serotonin receptors in the cortex. The volume is organized into several sections offering a broad spectrum of opinions on how the monoamine systems affect cortical function from a cellular/sub-cellular level to a system level. The complexity of these interactions are discussed in light of recent data showing how disruption of these systems dramatically affects the memory formation and information processing in the cortex.
Molecular Pain
This book focus on molecular and synaptic mechanisms for pain transmission, modulation and plasticity. Unlike traditional textbooks about pain, this book covers recent progress in neuroscience and relates these developments to the basic mechanisms of chronic pain. The book also discusses current pain medicine and alternative pain treatments such as acupuncture.
Molecular Chaperones in Health and Disease
Molecular chaperones are involved in a wide variety of essential cellular processes in living cells. A subset of molecular chaperones have been initially described as heat shock proteins protecting cells from stress damage by keeping cellular proteins in a folding competent state and preventing them from irreversible aggregation. Later it became obvious that molecular chaperones are also expressed constitutively in the cell and are involved in complex processes such as protein synthesis, intracellular protein transport, post-translational modification and secretion of proteins as well as receptor signalling. Hence, it is not surprising that molecular chaperones are implicated in the pathogenesis of many relevant diseases and could be regarded as potential pharmacological targets. Starting with the analysis of the mode of action of chaperones at the molecular, cellular and organismic level, this book will then describe specific aspects where modulation of chaperone action could be of pharmacological and therapeutic interest.
Modulation of host gene expression and innate immunity by viruses
This book is reference on a relatively young area of research in which virology, cellular biology and molecular pathogenesis govern the principles of coinvestigation. Infection of a naïve (non-immune) host with a virus elicits an immediate response which results in a cascade of changes in the host, including an interferon response (innate immunity). The outcome of this interaction is influenced by the genes of the virus as well as the genes of the host. Interestingly, different viruses do it in different ways. Not only is there a plethora of mechanisms used by the invading organisms, but the host has also evolved a great variety of redundant and robust countermeasures. This interplay of host and virus represents one of the most significant frontiers in biology today. A clearer understanding of the mechanisms involved will arm us with better strategies to deal with viruses, including emerging pathogens and potential bioterrorism agents. This book is sure to benefit students, scientists, and physicians working in the areas of virology, immunology, microbiology, and infectious diseases.
