One of the most successful methodology that arose from the worldwide diffusion of Fuzzy Logic is Fuzzy Control. After the first attempts dated in the seventies, this methodology has been widely exploited for controlling many industrial components and systems. At the same time, and very independently from Fuzzy Logic or Fuzzy Control, the birth of the Web has impacted upon almost all aspects of computing discipline. Evolution of Web, Web2.0 and Web 3.0 has been making scenarios of ubiquitous computing much more feasible; consequently information technology has been thoroughly integrated into everyday objects and activities. What happens when Fuzzy Logic meets Web technology? Interesting results might come out, as you will discover in this book. Fuzzy Mark-up Language is a son of this synergistic view, where some technological issues of Web are re-interpreted taking into account the transparent notion of Fuzzy Control, as discussed here. The concept of a Fuzzy Control that is conceived and modeled in terms of a native web wisdom represents another step towards the last picture of Pervasive Web Intelligence.

William Gibson, author of the extraordinary multiaward-winning novel Neuromancer, has written his most brilliant and thrilling work to date . . .The Mona Lisa Overdrive. Enter Gibson's unique world—lyric and mechanical, sensual and violent, sobering and exciting—where multinational corporations and high tech outlaws vie for power, traveling into the computer-generated universe known as cyberspace. Into this world comes Mona, a young girl with a murky past and an uncertain future whose life is on a collision course with internationally famous Sense/Net star Angie Mitchell. Since childhood, Angie has been able to tap into cyberspace without a computer. Now, from inside cyberspace, a kidnapping plot is masterminded by a phantom entity who has plans for Mona, Angie, and all humanity, plans that cannot be controlled . . . or even known. And behind the intrigue lurks the shadowy Yazuka, the powerful Japanese underworld, whose leaders ruthlessly manipulate people and events to suit their own purposes . . . or so they think.

This book models an idealized neuron as being driven by basic electrical elements, the goal being to systematically characterize the logical properties of neural pulses. In order to constitute a system, neurons as pulsating devices may be represented using novel circuit elements as delineated in this book. A plausible brain system is implied by the delineated elements and logically follows from known and likely properties of a neuron. New to electrical science are novel pulse-related circuit elements involving recursive neurons. A recursive neuron, when properly excited, produces a self-sustaining pulse train that when sampled, provides a true output with a specified probability, and a false output with complementary probability. Because of its similarity to the qubits of quantum mechanics, the recursive pulsating neuron is termed a simulated qubit. Recursive neurons easily function as controlled toggle devices and so are capable of massively parallel calculations, this being a new dimension in brain functioning as described in this book. Simulated qubits and their possibilities are compared to the qubits of quantum physics. Included in the book are suggested neural circuits for associative memory search via a randomized process of cue selection, and neural circuits for priority calculations. These serve to select returns from long term memory, which in turn determines one's next conscious thought or action based on past memorized experiences. The book reports on proposals involving electron tunneling between synapses, and quantum computations within neurons. Although not a textbook, there are easy exercises at the ends of chapters, and in the appendix there are twelve simulation experiments concerning neurons. ​

Cancer is one of the leading killers in the world and the incidence is increasing, but most cancer patients and cancer survivors suffer much from the disease and its conventional treatments’ side effects. In the past, clinical data showed that some complementary and alternative medicine (CAM) possessed anticancer abilities, but some clinicians and scientists have queried about the scientific validity of CAM due to the lack of scientific evidence. There is great demand in the knowledge gap to explore the scientific and evidence-based knowledge of CAM in the anticancer field. With this aim, a book series is needed to structurally deliver the knowledge to readers. Throughout the past few years, the cancer chemopreventive potencies and treatment effects of a number of natural dietary agents present in different food sources have been evaluated by various experiments. Some of them have progressed to early clinical trials. This volume is a specialized book presenting the research evidence relevant to the use of specific diet therapy in cancer chemoprevention and treatment. We begin with lessons learned from dietary resveratrol as an effective agent with anticancer properties against malignancies, followed examples of flavonoids from fruits and vegetables in the prevention and treatment of cancer. Evidence for the beneficial influence of diet enriched with flax seed oil and green tea on cancer will be reviewed. Soy food intake may enhance the effects on anticancer treatment for breast cancer, whereas lycopene-rich foods may possess chemopreventive efficacy. There are also discussions on the contribution of the cancer preventive effects of the antioxidant-rich foods and Mediterranean diet. In addition, the modulation of proteasome pathways by nutraceuticals is highlighted. Finally, we close the book with a discussion on the attenuation of cell survival signaling by bioactive phytochemicals in the prevention and therapy cancer.

The KiddyCAT is an easily administered standardized and normed test procedure that makes it possible to quickly determine if the speech-associated attitude of a preschool or kindergarten child is like that of youngsters who stutter or those who do not. A child's attitude toward his or her speech is a significant dimension that serves to supplement dysfluency in the identification of children who stutter. It is also an element that needs to be evaluated relative to clinical decision making.
