Book Description
The first Interfaces Conference was held at Swansea in April 1988 and represented the then state of the art of the science of implant surgery. The motivation for the initial venture was a supposed need for a closer interaction and dialogue between the clinician and scientist working in this area. As expressed in the Preface to the first Conference, we felt that the interface was represented graphically, scientifically and psychologically by the drawings of Edgar Rubins (1915), again widely used in the literature to the present Proceedings. The first Conference, we believe, achieved the aims of the organisers in bringing together scientists and clinicians towards an exchange of ideas by logically pursuing the sequence of events in clinical implant surgery. The present Conference, in collaboration with our Italian colleagues, has also attempted to achieve the same aims by examining the behaviour of implants constructed of a variety of materials in both hard and soft tissue. Many contributions in the conference employed the technique of finite element analysis, both for design and optimisation purposes, particularly in relation to bone remodelling. Indeed, this particular aspect of the Conference led to much debate and will require a major examination of the many levels of physical, chemical and biomechanical interactive behaviour of the implant and its environment. All this natural behaviour was presented and discussed, but difficulties and failures remain with such procedures and we feel it is only by continuing such meetings that we progress in this difficult area of clinical science.

Book Description
The thirty nine papers accepted for pub1 ication in the First International Conference on 'Interfaces in Medicine & Meehani cs' at Swansea in Apri 1, 1988 represent the current state of the art in the science of implant surgery. This initial venture was planned and undertaken when the present editors and their colleagues realised the need for a closer interaction and dialogue between the clinician and. those basic scientists working in the area of implant surgery. Thi s interface, together with the real interface at the material/tissue borders, thus forms the basis of the present conference. These two ideas, we felt, were nicely and effectively captured in the drawing by Edgar Rubins (1915), a perception psycho 1 ogi st, used on the book cover and elsewhere in our 1 iterature. The Proceedings were planned with some difficulty, due to the wi de scope of the conference. However, we felt the best format was to follow the logical progression of implant development. The introductory papers and talks therefore demonstrate the scope of surgical implants in current use. The development of an implant starts with modelling of the proposed implant and its potential environment and the proceedings follow the same format. Following this, materials in current use are discussed.

Book Description
Noninvasive mechanical ventilation is an effective technique for the management of patients with acute or chronic respiratory failure. This comprehensive and up-to-date book explores all aspects of the subject. The opening sections are devoted to theory and equipment, with detailed attention to the use of full-face masks or helmets, the range of available ventilators, and patient-ventilator interactions. Clinical applications are then considered in depth in a series of chapters that address the use of noninvasive mechanical ventilation in chronic settings and in critical care, both within and outside of intensive care units. Due attention is also paid to weaning from conventional mechanical ventilation, potential complications, intraoperative applications, and staff training. The closing chapters examine uses of noninvasive mechanical ventilation in neonatal and pediatric care. This book, written by internationally recognized experts, will be an invaluable guide for both clinicians and researchers.

Book Description
Since 2002, the Tohoku University Graduate School of Dentistry has proposed “Interface Oral Health Science” as a major theme for next-generation dental research. That theme is based on the innovative concept that healthy oral function is provided by biological and biomechanical harmony among three systems: (1) oral tissues including the teeth, mucosa, bones, and muscles (host); (2) parasitic microorganisms of the oral cavity (parasites); and (3) biomaterials. The concept posits that oral diseases such as dental caries, periodontal disease, and tempo- mandibular disorders should be interpreted as interface diseases that result from disruption of the intact interfaces among these systems. The uniqueness of this concept rests on the fact that it not only encompasses the entire ? eld of dentistry and dental care, but also expands the common ground shared with many other ? elds, including medicine, pharmaceutical science, agriculture, material science, and engineering. Our Graduate School of Dentistry aims to promote advances in dental research and to activate interdisciplinary research with related ? elds by putting interface oral health science into practice. On this basis we organized the First International Symposium for Interface Oral Health in February 2005, with productive discussions stimulated by two special lectures, three symposia, and poster presentations. A monograph titled Interface Oral Health Science that s- marized the contents of the symposium was published in the autumn of 2005 (International Congress Series 1284, Elsevier, Amsterdam). The Second International Symposium was the most recent.

Book Description
Capacitive micromachined ultrasonic transducers (CMUTs), have been widely studied in academia and industry over the last decade. CMUTs provide many benefits over traditional piezoelectric transducers including improvement in performance through wide bandwidth, and ease of electronics integration, with the potential to batch fabricate very large 2D arrays with low-cost and high-yield. Though many aspects of CMUT technology have been studied over the years, packaging the CMUT into a fully practical system has not been thoroughly explored. Two important interfaces of packaging that this thesis explores are device encapsulation (the interface between CMUTs and patients) and full electronic integration of large scale 2D arrays (the interface between CMUTs and electronics). In the first part of the work, I investigate the requirements for the CMUT encapsulation. For medical usage, encapsulation is needed to electrically insulate the device, mechanically protect the device, and maintain transducer performance, especially the access of the ultrasound energy. While hermetic sealing can protect many other MEMS devices, CMUTs require mechanical interaction to a fluid, which makes fulfilling the previous criterion very challenging. The proposed solution is to use a viscoelastic material with the glass-transition-temperature lower than room temperature, such as Polydimethylsiloxane (PDMS), to preserve the CMUT static and dynamic performance. Experimental implementation of the encapsulated imaging CMUT arrays shows the device performance was maintained; 95 % of efficiency, 85% of the maximum output pressure, and 91% of the fractional bandwidth (FBW) can be preserved. A viscoelastic finite element model was also developed and shows the performance effects of the coating can be accurately predicted. Four designs, providing acoustic crosstalk suppression, flexible substrate, lens focusing, and blood flow monitoring using PDMS layer were also demonstrated. The second part of the work, presents contributions towards the electronic integration and packaging of large-area 2-D arrays. A very large 2D array is appealing for it can enable advanced novel imaging applications, such as a reconfigurable array, and a compression plate for breast cancer screening. With these goals in mind, I developed the first large-scale fully populated and integrated 2D CMUTs array with 32 by 192 elements. In this study, I demonstrate a flexible and reliable integration approach by successfully combining a simple UBM preparation technique and a CMUTs-interposer-ASICs sandwich design. The results show high shear strength of the UBM (26.5 g), 100% yield of the interconnections, and excellent CMUT resonance uniformity ([lowercase Sigma] = 0.02 MHz). As demonstrated, this allows for a large-scale assembly of a tile-able array by using an interposer. Interface engineering is crucial towards the development of CMUTs into a practical ultrasound system. With the advances in encapsulation technique with a viscoelastic polymer and the combination of the UBM technique to the TSV fabrication for electronics integration, a fully integrated CMUT system can be realized.

Book Description
This book is the first comprehensive reference on the interface between neurology and internal medicine. In 171 chapters organized by organ system, the book examines the neurologic manifestations of dozens of medical conditions, the neurologic effects of drugs, organ transplantation, and other treatments, and the medical comorbidities or complications—iatrogenic or otherwise—that neurologists must diagnose and treat in patients with neurologic disease. Most chapters are co-authored by a neurologist and a non-neurologic specialist. Each chapter presents information in an accessible format and includes a case vignette and the authors' recommendations for the case. A companion Website provides a multiple-choice question for each chapter and the fully searchable text, with case vignettes and recommendations linked.

Book Description
The Tohoku University Graduate School of Dentistry first introduced the concept of “Interface Oral Health Science”, designed to establish and maintain healthy oral cavities, which are home to a number of mixed systems. Included in those systems are: (1) host tissues such as teeth, mucosa, muscle and bone, (2) parasites and microorganisms cohabiting the surfaces of the oral cavity and (3) biomaterials that are used for the rehabilitation of oral functions. In addition, (4) these systems are subject to severe and complex mechanical forces. Therefore, it is critical to promote dental studies that integrate a wide range of interdisciplinary research as medicine, agriculture, material science, engineering, and pharmacology. With this incentive, international symposiums for interface oral health science have been held several times in the past. The concept has since refined and expanded, the result being the “Biosis-Abiosis Intelligent Interface,” and projects aiming at the creation of highly functional and autonomic intelligent interfaces are ongoing. This book brings together a number of studies on incentives and projects by leading authors. Topics include biosis-abiosis interface of dental implants, biomaterials in interface science, biomedical engineering interface and cell manipulation and tissue regeneration. Readers not only from the field of dentistry but also many related areas will find this book a valuable resource.
