The study of the genetic basis for evolution has flourished in this century, as well as our understanding of the evolvability and programmability of biological systems. Genetic algorithms meanwhile grew out of the realization that a computer program could use the biologically-inspired processes of mutation, recombination, and selection to solve hard optimization problems. Genetic and evolutionary programming provide further approaches to a wide variety of computational problems. A synthesis of these...

Particulates of fungi, bacteria, pollen grains, protists, and viruses are carried by wind around the globe. When they fall to Earth in polar...

At Princeton Tec, we've been pioneering new technologies and building lights for more than three decades. And yes, you could say it's been quite a ride. In our pursuit to be the world's best, we've travelled the earth by ocean, by air, by bike and by foot. We've consulted great athletes, scaled mountains, traversed the poles, touched the ocean floors and rolled two wheels on every continent. We are constantly inspired by what our ever evolving environments have to offer and the human spirit that...

This book is intended for epidemiologists, evolutionary biologists, and health-care professionals, real-time and predictive modeling of infectious disease is of growing importance. It provides a timely and comprehensive introduction to the modeling of infectious diseases in humans and animals, focusing on recent developments as well as more traditional approaches. Matt Keeling and Pejman Rohani move from modeling with simple differential equations to more recent, complex models, where spatial structure...

Bonner studies slime molds in an attempt to seek a picture of the first elements of communication between cells. He discusses what has been learned by looking at their developmental biology, including recent advances in our molecular understanding of the process and generates insights into how cell-to-cell cooperation might have originated.

Nearly 90 percent of the earth's land surface is directly affected by human infrastructure and activities, yet less than 5 percent is legally "protected" for biodiversity conservation. Even within that 5 percent, seven out of ten large protected areas have people living inside their boundaries. This means that in 96.5% of the world, conservation includes people. Conservation is a resource for conservation practitioners, students, managers, and policy makers hoping to make conservation work where...

Since its launch in 1993 by the nonprofit U.S. Green Building Council, the Leadership in Energy and Environmental Design (LEED) program has become the standard measure of sustainability for buildings worldwide. Successfully reaching one of four LEED certification levels--Certified, Silver, Gold, or Platinum--requires specific point totals, which differ among building types. Getting certified, in addition to altruistic benefits, allows building owners to take advantage of a growing number of state...

The physics of neutrinos – uncharged elementary particles that are key to helping us better understand the nature of our universe – is one of the most exciting frontiers of modern science. This book provides a comprehensive overview of neutrino physics today and explores promising new avenues of inquiry that could lead to future breakthroughs. The Physics of Neutrinos begins with a concise history of the field and a tutorial on the fundamental properties of neutrinos, and goes on to discuss how...

There is more to a bird than simply feathers. And just because birds evolved from a single flying ancestor doesn't mean they are structurally all the same.

This book provides an introduction to the mathematics needed to model, analyze, and design feedback systems. It is an ideal textbook for undergraduate and graduate students, and is indispensable for researchers seeking a self-contained reference on control theory. Unlike most books on the subject, "Feedback Systems" develops transfer functions through the exponential response of a system, and is accessible across a range of disciplines that utilize feedback in physical, biological, information...

Unlike other guides, which provide isolated individual photographs or illustrations, this book features large, lifelike scenes for each species. These scenes - 680 in all - are each composed of 12-20 color images showing the bird in a wide range of views, both near and far, from different angles, in various plumages and behaviors, including flight, and in the habitat in which they live. These compositions show how a bird's appearance changes with distance, and give equal emphasis to characteristics...

In the first fractions of a second after the big bang lingers a question at the heart of our very existence: why does the universe contain matter but almost no antimatter? The laws of physics tell us that equal amounts of matter and antimatter were produced in the early universe - but then, something odd happened. Matter won out over antimatter; had it not, the universe today would be dark and barren. But how and when did this occur? Helen Quinn and Yossi Nir guide readers into the very heart of...
