The development of micro/nanofiber sensors and associated integrated systems is a major project spanning photonics, engineering, and materials science, and has become a key academic research trend. During the development of miniature optical sensors, different materials and micro/nanostructures have been reasonably designed and functionalized on the ordinary single-mode optical fibers. The combination of various special optical fibers and new micro/nanomaterials has greatly improved the performance of the sensors. In terms of optical integration, micro/nanofibers play roles in independent and movable optical waveguide devices, and can be conveniently integrated into two-dimensional chips to realize the efficient transmission and information exchange of optical signals based on optical evanescent field coupling technology. In terms of systematic integration, the unique optical transmission mode of optical fiber has shown great potential in the array and networking of multiple sensor units.In this book, more than ten research papers were collected and studied, presenting research on optical micro/nanofiber devices and related integrated systems, covering high-performance optical micro/nanofiber sensors, fine characterization technologies for optical micro/nanostructures, weak signal detection technologies in photonic structures, as well as fiber-assisted highly integrated optical detection systems.

Presenting recent advances in clinical diagnosis and treatment derived from an increased understanding of the biology of the hip, this unique text examines hip disease and pathophysiology through the lenses of kinematics, biomechanics, anatomy and metabolism. Opening chapters examine the impact of health care organization on hip care and prevalence and burden of osteoarthritis¿.Biomechanical considerations of the hip and gait pathomechanics in hip disease are then discussed, followed by chapters covering femoroacetabular impingement, possible links between OA and metabolic syndrome, osteonecrosis, osteoporosis and Paget's disease. Considerations of risk reduction¿ surrounding hip arthroplasty conclude the text, including device and surgical options for THA, hip sepsis and prevention of perioperative infection, and management of venous thromboembolism. Taken together, this represents a new and important context for the discussions and management of hip disease for orthopedic surgeons and researchers alike.

This book is an organized approach to understanding bone growth and disease. It integrates anatomic and radiologic knowledge of enchondral and membranous bone growth and emphasizes the similarities of the physis and acrophysis in development. The identification of abnormality is aided by the explanations of the causes in terms of pattern recognition. The artwork, jointly produced by artist and author, illustrates the concepts covered. While mainly written for trainees in radiology, pediatrics, and orthopedics, it will also be useful to practitioners in these fields.
