I did have fantastic hearing, mostly by virtue of being blind. But that couldn't actually mean that he's trying to tell me I have super powers, right? Because that would be ridiculous. It wasn't the "sex talk" he expected. Phillip Sallinger's dad has told him he's a custodian--a guardian--and his genetically inherited power is telekinesis. He'll learn to move objects with his mind. Excited to begin superhero high school until he discovers he's assigned to a "special ed" class for disabled empowered kids, he suddenly feels like an outsider. Bullied, threatened, and betrayed, Phillip struggles, even as he and his friends--calling themselves the Ables--find ways to maximize their powers to overcome their disabilities, and are the first to identify the growing evil threatening humanity. As vital custodians disappear and the custodian leadership is mired in indecision, a mysterious and powerful figure taunts Phillip, and the enemy is poised to strike. But what if the next "one who does all," the multi-gifted custodian predicted to come, is one of the Ables?

Set four years after the events of Strings, Currents finds the Ables gang about to start their second year at Goodspeed University. Phillip is struggling more than ever with anxiety and PTSD, and he continues to feel tremendous guilt over the loss of a friend. It's haunting him. He's having vivid nightmares, passing out frequently, and starting to question his role in the world. On top of all that, he's taking his first public speaking course, and the learning curve is steep--though he does make a new friend in the class. Phillip also finds himself truly blind once again, with no one to give him even temporary sight. He and his girlfriend, Emmaline, have created a sort of shorthand that allows her to communicate enemy positions so that Phillip can still be an effective crime fighter. Sherpa, his dog, is proving just as helpful during hero work as she is in the day-to-day things Phillip needs help with. There's more distance between Phillip & Bentley now, and the reasons aren't entirely understood by either of them. As Phillip tries to keep it together and rebuild an old friendship, the group of college heroes chases a new energy-hoarding villain across the globe, desperate to understand the danger in time to stop it. By the end, few of them will ever be the same.

Strings is the second book in the fast-paced, captivating Ables series from Jeremy Scott, a bold new voice in fantasy and sci- fi, and already a widely popular storyteller as co-creator and narrator of CinemaSins, a YouTube channel that has amassed more than 8 million subscribers. In this exciting and action-packed continuation, our heros are confronted with a mysterious new villain wielding a previously unknown power. Phillip, Bentley, & Henry will be forced to stretch their abilities and their bonds further than ever before.

“Highly original . . . Ample dry humor leavens a plotline that thoughtfully explores the heart of human darkness . . . Michael Koryta admirers will be enthralled.” —Publishers Weekly, starred review “What appears to be a humorous story set in Indiana farm country becomes a thriller with multiple shocking twists. Fans of TV's Dexter might want to try this disquieting book from Scott.” —Library Journal In the early 1980s, a tight-knit Indiana community is struck by a series of violent murders. Father Solomon Lancaster—the town’s dry-witted sheriff and priest at the community Catholic church—finds himself on the forefront of the investigation. Soon, he’s fighting to match wits with the serial killer terrorizing his town while trying to justify his law enforcement credentials to the FBI as their analysts and profilers take Crooked Creek, Indiana, by storm. But Father Solomon is hiding secrets of his own. Ones that threaten to rise to the surface as the murders continue and the investigation draws nearer to the truth. As the killer begins to escalate, Father Solomon finds that even the innocent have dark sides, and trust might be the deadliest weapon of all.

The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory

This book provides an introduction to the mathematical and algorithmic foundations of data science, including machine learning, high-dimensional geometry, and analysis of large networks. Topics include the counterintuitive nature of data in high dimensions, important linear algebraic techniques such as singular value decomposition, the theory of random walks and Markov chains, the fundamentals of and important algorithms for machine learning, algorithms and analysis for clustering, probabilistic models for large networks, representation learning including topic modelling and non-negative matrix factorization, wavelets and compressed sensing. Important probabilistic techniques are developed including the law of large numbers, tail inequalities, analysis of random projections, generalization guarantees in machine learning, and moment methods for analysis of phase transitions in large random graphs. Additionally, important structural and complexity measures are discussed such as matrix norms and VC-dimension. This book is suitable for both undergraduate and graduate courses in the design and analysis of algorithms for data.
