Gilded Age sisters face terrible monsters and their own haunted past in this “thought-provoking, atmospheric, and utterly bewitching” YA novel (Booklist, starred review). Growing up on their family’s Oregon farm, Trudchen Grey believed every word of her older sister Odette’s fantastical stories. But now that Tru’s gotten older, she’s starting to wonder if those tales of their monster-slaying mother were just comforting lies. There’s certainly nothing fantastic about Tru’s own life—permanently disabled and in constant pain from childhood polio. In 1909, after a two-year absence, Od reappears with a suitcase supposedly full of weapons—and a promise to rescue Tru from the monsters on their way to attack her. But it’s Od who seems haunted by something. And when the sisters’ search for their mother leads them to a face-off with the Leeds Devil, a nightmarish beast that’s wreaking havoc in the Mid-Atlantic states, Tru discovers the peculiar possibility that she and her sister—despite their dark pasts and ordinary appearances—might, indeed, have magic after all.

Soft computing is a branch of computer science that deals with a family of methods that imitate human intelligence. This is done with the goal of creating tools that will contain some human-like capabilities (such as learning, reasoning and decision-making). This book covers the entire gamut of soft computing, including fuzzy logic, rough sets, artificial neural networks, and various evolutionary algorithms. It offers a learner-centric approach where each new concept is introduced with carefully designed examples/instances to train the learner.

"Attractive and well-written introduction." — Journal of Symbolic Logic The logic that mathematicians use to prove their theorems is itself a part of mathematics, in the same way that algebra, analysis, and geometry are parts of mathematics. This attractive and well-written introduction to mathematical logic is aimed primarily at undergraduates with some background in college-level mathematics; however, little or no acquaintance with abstract mathematics is needed. Divided into three chapters, the book begins with a brief encounter of naïve set theory and logic for the beginner, and proceeds to set forth in elementary and intuitive form the themes developed formally and in detail later. In Chapter Two, the predicate calculus is developed as a formal axiomatic theory. The statement calculus, presented as a part of the predicate calculus, is treated in detail from the axiom schemes through the deduction theorem to the completeness theorem. Then the full predicate calculus is taken up again, and a smooth-running technique for proving theorem schemes is developed and exploited. Chapter Three is devoted to first-order theories, i.e., mathematical theories for which the predicate calculus serves as a base. Axioms and short developments are given for number theory and a few algebraic theories. Then the metamathematical notions of consistency, completeness, independence, categoricity, and decidability are discussed, The predicate calculus is proved to be complete. The book concludes with an outline of Godel's incompleteness theorem. Ideal for a one-semester course, this concise text offers more detail and mathematically relevant examples than those available in elementary books on logic. Carefully chosen exercises, with selected answers, help students test their grasp of the material. For any student of mathematics, logic, or the interrelationship of the two, this book represents a thought-provoking introduction to the logical underpinnings of mathematical theory. "An excellent text." — Mathematical Reviews

Quintessence collects Quine’s classic essays in one volume, offering a much-needed introduction to his general philosophy. The selections take up analyticity and reductionism; the indeterminacy of translation of theoretical sentences and the inscrutability of reference; ontology; naturalized epistemology; philosophy of mind; and extensionalism.

This book constitutes selected papers from the refereed proceedings of the 14th International Workshop on Rewriting Logic and Its Applications, WRLA 2022, held in Munich, Germany, in April 2022. The 9 full papers included in this book were carefully reviewed and selected from 13 submissions. They focus on topics in rewriting logic and its applications. The book also contains 2 invited papers, 2 invited tutorials and an experience report.
