When seventeen-year-old Toby McGonigal finds himself lost in space, separated from his family, he expects his next drift into cold sleep to be his last. After all, the planet he's orbiting is frozen and sunless, and the cities are dead. But when Toby wakes again, he's surprised to discover a thriving planet, a strange and prosperous galaxy, and something stranger still—that he's been asleep for 14,000 years. Welcome to the Lockstep Empire, where civilization is kept alive by careful hibernation. Here cold sleeps can last decades and waking moments mere weeks. Its citizens survive for millennia, traveling asleep on long voyages between worlds. Not only is Lockstep the new center of the galaxy, but Toby is shocked to learn that the Empire is still ruled by its founding family: his own. Toby's brother Peter has become a terrible tyrant. Suspicious of the return of his long-lost brother, whose rightful inheritance also controls the lockstep hibernation cycles, Peter sees Toby as a threat to his regime. Now, with the help of a lockstep girl named Corva, Toby must survive the forces of this new Empire, outwit his siblings, and save human civilization. Karl Schroeder's Lockstep is a grand innovation in hard Science Fiction space opera. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

In a simple and accessible way it extends embedding field theory into areas of machine intelligence that have not been clearly dealt with before. Neural Networks for Pattern Recognition takes the pioneering work in artificial neural networks by Stephen Grossberg and his colleagues to a new level. In a simple and accessible way it extends embedding field theory into areas of machine intelligence that have not been clearly dealt with before. Following a tutorial of existing neural networks for pattern classification, Nigrin expands on these networks to present fundamentally new architectures that perform realtime pattern classification of embedded and synonymous patterns and that will aid in tasks such as vision, speech recognition, sensor fusion, and constraint satisfaction. Nigrin presents the new architectures in two stages. First he presents a network called Sonnet 1 that already achieves important properties such as the ability to learn and segment continuously varied input patterns in real time, to process patterns in a context sensitive fashion, and to learn new patterns without degrading existing categories. He then removes simplifications inherent in Sonnet 1 and introduces radically new architectures. These architectures have the power to classify patterns that may have similar meanings but that have different external appearances (synonyms). They also have been designed to represent patterns in a distributed fashion, both in short-term and long-term memory.

Lockstep and Dance: Images of Black Men in Popular Culture examines popular culture's reliance on long-standing stereotypes of black men as animalistic, hypersexual, dangerous criminals, whose bodies, dress, actions, attitudes, and language both repel and attract white audiences. Author Linda G. Tucker studies this trope in the images of well-known African American men in four cultural venues: contemporary literature, black-focused films, sports commentary, and rap music. Through rigorous analysis, the book argues that American popular culture's representations of black men preserve racial hierarchies that imprison blacks both intellectually and physically. Of equal importance are the ways in which black men battle against, respond to, and become implicated in the production and circulation of these images. Tucker cites examples ranging from Michael Jordan's underwear commercials and the popular Barbershop movies to the career of rapper Tupac Shakur and John Edgar Wideman's memoir Brothers and Keepers. Lockstep and Dance tracks the continuity between historical images of African American men, the peculiar constitution of whites' anxieties about black men, and black men's tolerance of and resistance to the reproduction of such images. The legacy of these stereotypes is still apparent in contemporary advertising, film, music, and professional basketball. Lockstep and Dance argues persuasively that these cultural images reinforce the idea of black men as prisoners of American justice and of their own minds but also shows how black men struggle against this imprisonment.
