This rigourous and self-contained book describes mathematicaland, in particular, stochastic methods to assess the performance ofnetworked systems. It consists of three parts. The first part is areview on probability theory. Part two covers the classical theoryof stochastic processes (Poisson, renewal, Markov and queuingtheory), which are considered to be the basic building blocks forperformance evaluation studies. Part three focuses on therelatively new field of the physics of networks. This part dealswith the recently obtained insights that many very different largecomplex networks - such as the Internet, World Wide Web, proteins,utility infrastructures, social networks - evolve and behaveaccording to more general common scaling laws. This understandingis useful when assessing the end-to-end quality of communicationsservices, for example, in Internet telephony, real-time video andinteracting games. Containing problems and solutions, this book isideal for graduate students taking courses in performanceanalys

Anthrax. Smallpox. Incurable and horrifying Ebola-relatedfevers. For two decades, while a fearful world prepared for nuclearwinter, an elite team of Russian bioweaponeers began to till a newkilling field: a bleak tract sown with powerful seeds of massdestruction--by doctors who had committed themselves to creating abiological Armageddon. Biohazard is the never-before-told story ofRussia's darkest, deadliest, and most closely guarded Cold Warsecret. No one knows more about Russia's astounding experiments withbiowarfare than Ken Alibek. Now the mastermind behind Russia's germwarfare effort reveals two decades of shocking breakthroughs...howMoscow's leading scientists actually reengineered hazardousmicrobes to make them even more virulent...the secrets behind thediscovery of an invisible, untraceable new class of biologicalagents just right for use in political assassinations...thestartling story behind Russia's attempt to turn a sample of theAIDS virus into the ultimate bioweapon. And in a chilling

A riveting tale of the battle over genetically engineeredfoods, and an inside look at a biotech food empire. Ultimately astory of idealism, and conflicting dreams about the shape of abetter world. Softcover.

An unparalleled history of astronomy presented in the words ofthe scientists who made the discoveries. Here are the writings ofCopernicus, Galileo, Kepler, Newton, Halley, Hubble, and Einstein,as well as that of dozens of others who have significantlycontributed to our picture of the universe. From Aristotle's proof that the Earth is round to the 1998 paperthat posited an accelerating universe, this book contains 100entries spanning the history of astronomy. Award-winning sciencewriter Marcia Bartusiak provides enormously entertainingintroductions, putting the material in context and explaining itsplace in the literature. Archives of the Universe is essentialreading for professional astronomers, science history buffs, andbackyard stargazers alike.

Research clearly indicates that ethnic groups differsignificantly on levels of mental and physical health, antisocialbehavior, and educational attainment. This book explains thesevariations among ethnic groups with respect to their psychologicaland social functioning and tests competing hypotheses about themechanisms that might cause the functioning to be better, worse, ordifferent in pattern from other groups. Attention is paid toeducational attainments, antisocial behavior, schizophrenia andsuicide, and to the complex and changing patterns of ethnicidentity. The book also focuses on evidence on risk and protectivefactors that is used systematically to ask whether such factorsmight account for the differences in both migration histories andethnic mixture. It concludes with a discussion of the multiplemeanings of ethnicity, the major variations among ethnic groups,and the policy implications of the findings discussed in thebook.

In this fascinating volume, today’s foremost scientistsdiscuss their own versions and visions of Einstein: how he hasinfluenced their worldviews, their ideas, their science, and theirprofessional and personal lives. These twenty-four essays are atestament to the power of scientific legacy and are essentialreading for scientist and layperson alike. Contributors include: Roger Highfield on the Einstein myth John Archibald Wheeler on his meetings with Einstein Gino C. Segrè, Lee Smolin, and Anton Zeilinger on Einstein’sdifficulties with quantum theory Leon M. Lederman on the special theory of relativity Frank J. Tipler on why Einstein should be seen as a scientificreactionary rather than a scientific revolutionary

Thinking about moving to mars? Well, why not? Mars, after all,is the planet that holds the greatest promise for humancolonization. But why speculate about the possibilities when youcan get the real scientific scoop from someone who's been happilyliving and working there for years? Straight from thenot-so-distant future, this intrepid pioneer's tips for physical,financial, and social survival on the Red Planet cover: - How toget to Mars (Cycling spacecraft offer cheap rides, but the smell isnot for everyone.)- Choosing a spacesuit (The old-fashioned butreliable pneumatic Neil Armstrong style versus the sleek new--butanatomically unforgiving--elastic "skinsuit.")- Selecting a habitat(Just like on Earth: location, location, location.)- Finding a jobthat pays well and doesn't kill you (This is not a metaphor onMars.)- How to meet the opposite sex (Master more than fortyMars-centric pickup lines.)
