Today, organizations want to scale Scrum to ever larger and more complex projects, driving the benefits of agility throughout the enterprise. But most conventional solutions to scaling agility have added complexity and deviated from the principles that make Scrum so attractive. The Nexus Framework for Scaling Scrum introduces a better approach, reflecting the authors' many years of applying and scaling Scrum in multiple industries. Three leading Scrum.org experts introduce the Nexus Framework, showing how it enables smooth integration among multiple Scrum teams, as well as highly-effective collaboration with non-Scrum teams working on the same project. Drawing on their immense experience, they explain what Nexus is, how it works, and how it solves agile scalability problems that have bedeviled organizations for years. Next, they offer start-to-finish guidance for applying Nexus Framework principles throughout your own organization. You will walk through forming a Nexus, organizing work in a Nexus environment, managing and enabling a Nexus, and much more-all you need to succeed with Scrum in even the most challenging global projects.

Photorefractive polymer composites are an unusually sensitive class of photopolymers. Physics of Photorefraction in Polymers describes our current understanding of the physical processes that produce a photorefractive effect in key composite materials. Topics as diverse as charge generation, dispersive charge transport, charge compensation and trapping, molecular diffusion, organic composite structure, and nonlinear optical wave coupling are all developed from a physical perspective. Emphasis is placed on explaining how these physical processes lead to observable properties of the polymers, and the authors discuss various applications, including holographic archiving.
