This is a stunner.” —The BookView Review Would you change reality for love? Morally complex, orphan, and absolute genius Vincent Abajian is hellbent to uncover all he can on Artificial Intelligence. His relentless pursuit distracts him from a traumatic childhood loss—his childhood best friend Akane was engulfed in a time-turbulence, a random rift in space and time. But when a beautiful, temperamental, post-doctoral scientist, Emika Amari, joins his Center, everything changes. Vincent is convinced that Akane is inside the irresistible Emika. As they begin a life together, Vincent’s past and his connection with a time turbulence survivor challenge everything they’ve created and push them into a spiral of politics and conspiracy. Vincent’s silence to protect Emika threatens to tear them apart. Unknowingly, Emika is torn between what she wants and what Akane wants from her. With his newfound power, Vincent struggles with whether or not he should create another time-turbulence to free Emika from the grasp of Akane once and for all. But will tinkering with time be more destructive than anything he has ever encountered before?

The winding number is one of the most basic invariants in topology. It measures the number of times a moving point P goes around a fixed point Q, provided that P travels on a path that never goes through Q and that the final position of P is the same as its starting position. This simple idea has far-reaching applications. The reader of this book will learn how the winding number can help us show that every polynomial equation has a root (the fundamental theorem of algebra),guarantee a fair division of three objects in space by a single planar cut (the ham sandwich theorem),explain why every simple closed curve has an inside and an outside (the Jordan curve theorem),relate calculus to curvature and the singularities of vector fields (the Hopf index theorem),allow one to subtract infinity from infinity and get a finite answer (Toeplitz operators),generalize to give a fundamental and beautiful insight into the topology of matrix groups (the Bott periodicity theorem). All these subjects and more are developed starting only from mathematics that is common in final-year undergraduate courses.

When Jesse and Alexandra's youngest child Becca is taken from their home in the middle of the night, a happy family's life shatters. Jesse's grief triggers a full-blown psychiatric crisis, which spurs a most unusual spiritual quest in an attempt to find a way to feel at home in what suddenly seems like a cruel world. In the midst of her own trauma, Alexandra is diagnosed with Alzheimer's disease, further pitching the family into desperation. Jesse's weekly breakfast with his two sons, along with Alexandra's determined efforts to fight the erasure of her memories, holds the family together despite the agonizing uncertainty surrounding all of them, and the futility of their ongoing search efforts for Becca. Jesse and Alexandra find themselves drawn into the horrifying world of missing and abducted children and the minds of their captors, and eventually adopt an abduction survivor named Maddy and her young children. Together, they forge a new and expanded family, and create a home where everyone can heal. This is a family saga, a love story, an account of child abduction and its exacting aftermath, a tale of hard-won hope, and a profound exploration of the spiritual potential of ordinary life in the face of the unthinkable.

Jennifer Chiaverini's bestselling Elm Creek Quilts series continues with The Winding Ways Quilt, in which the arrival of newcomers into the circle of quilters heralds unexpected journeys down pathways near and far. Quilters have flocked to Elm Creek Manor to learn from Master Quilter Sylvia Compson and her expert colleagues. There's Sarah, Sylvia's onetime apprentice who's paired her quilting accomplishments with a mind for running the business of Elm Creek Quilts; Agnes, who has a gift for appliqué; Gwen, who stitches innovative art quilts; Diane, a whiz at the technicalities of quick-piecing; and Bonnie, with her encyclopedic knowledge of folk art patterns. But with Judy and Summer, two other founding members of the Elm Creek Quilters, departing to pursue other opportunities, will the new teachers be able to fill in the gaps created by the loss of their expertise—and more important, their friendship? "When I think of all the different paths I could have followed in my life, all the twists and turns that could have led me anywhere," muses incoming teacher Gretchen, "it's something of a miracle that I ended up here, surrounded by loving friends." But what of friends departed? As Sylvia contemplates a tribute to the partnership of the Elm Creek Quilters, she is reminded of a traditional quilt pattern whose curved pieces symbolize a journey. Winding Ways, a mosaic of overlapping circles and intertwining curves, would capture the spirit of their friendship at the moment of its transformation. Will Sylvia's choice inspire the founding members to remember that each is a unique part of a magnificent whole? Will the newcomers find ways to contribute, and to earn their place? The Winding Ways Quilt considers the complicated, often hidden meanings of presence and absence, and what change can mean for those who have come to rely upon one another.

This book presents the current coil winding methods, their associated technologies and the associated automation techniques. From the introduction as a forming joining process, over the physical properties of coils, the semifinished products (wire, coil body, insulation) are introduced. In the process chain, different winding methods are used for magnet wire winding. Finally, the automation of these processes is described.
