by Rebeka Rudolf Vojkan Lazić Peter Majerič Andrej Ivanič Gregor Kravanja Karlo T. Raić

This book focuses on recent advances in dental gold alloys and gold nanoparticles (GNPs) for biomedical applications. Dental gold alloys combine several highly desirable mechanical properties, such as high strength, ductility, and elasticity, with an extremely robust chemical stability in the mouth. Moreover, astonishing progress has been made in the use of GNPs as novel gold biomaterials that provide a multifunctional platform for cellular imaging, biosensing, and targeted drug delivery in tumour immunotherapy and photothermal therapy. Beginning with a comprehensive overview of the development and use of dental gold alloys, the book addresses the materials properties that are crucial for dental applications, focusing on aspects such as microstructure, chemical and mechanical stability, ageing, biocompatibility, and colour retention. The book then shifts focus to the use of GNPs in dental applications, delving into different techniques of GNP synthesis for specifically tailoring the size, shape, and stability of GNPs in biological media. In addition to these factors, it addresses how their exposure route, surface chemistry, as well as how the steric effects of their coating impact biodistribution and determine the level of GNP toxicity in the human body. Featuring topical literature reviews alongside up-to-date published experimental results, this book offers an attractive resource for practicing scientists and engineers working in the field of gold-based biomaterials.

Dental Pulp Stem Cells

by Sibel Yildirim

Stem cell technology is moving forward at a tremendous rate. Recent discoveries have surprised even the most expert researchers. While every piece of new data broadens the current knowledge and contributes to this moving forward, the new data also serve as paradigm shifters of fundamental knowledge of cell biology. While the question 'What is a Stem Cell' may now seem to basic to even discuss, there are still some discrepancies, however, between groups in terms of their functional roles. Teeth develop from the ectoderm of the first branchial arch and the ectomesenchyme of the neural crest. Deciduous teeth start to form between the sixth and eighth weeks, and permanent teeth begin to form in the twentieth weeks. Several studies have demonstrated that the pulp from both adult teeth and deciduous teeth contains dental pulp stem cells. Several factors have made them very attractive as a model system for many researchers; they are multipotent, ethically and non-controversially available in large numbers, immuno-compatible, developmentally primitive, easy to isolate and have high expansion potential in vitro. However, many controversies still exist in the field. There are several unanswered questions in the biology of dental pulp and odontoblasts. This new volume in the SpringerBriefs in Stem Cells series presents an evaluation of stem cells from human dental pulp as a reliable stem cell source for cell-based therapy to stimulate tissue regeneration.

The Department of Mad Scientists: How DARPA Is Remaking Our World, from the Internet to Artificial Limbs

by Michael Belfiore

The first-ever inside look at DARPA—the Defense Advanced Research Projects Agency—the maverick and controversial group whose futuristic work has had amazing civilian and military applications, from the Internet to GPS to driverless cars America's greatest idea factory isn't Bell Labs, Silicon Valley, or MIT's Media Lab. It's the secretive, Pentagon-led agency known as DARPA. Founded by Eisenhower in response to Sputnik and the Soviet space program, DARPA mixes military officers with sneaker-wearing scientists, seeking paradigm-shifting ideas in varied fields—from energy, robotics, and rockets to peopleless operating rooms, driverless cars, and planes that can fly halfway around the world in just hours. DARPA gave birth to the Internet, GPS, and mind-controlled robotic arms. Its geniuses define future technology for the military and the rest of us.Michael Belfiore was given unprecedented access to write this first-ever popular account of DARPA. Visiting research sites across the country, he watched scientists in action and talked to the creative, fearlessly ambitious visionaries working for and with DARPA. Much of DARPA's work is classified, and this book is full of material that has barely been reported in the general media. In fact, DARPA estimates that only 2 percent of Americans know much of anything about the agency. This fascinating read demonstrates that DARPA isn't so much frightening as it is inspiring—it is our future.

Dependability Engineering and Complex Systems

by Wojciech Zamojski Jacek Mazurkiewicz Jarosław Sugier Tomasz Walkowiak Janusz Kacprzyk

These proceedings present the results of the Eleventh International Conference on Dependability and Complex Systems DepCoS-RELCOMEX which took place in a picturesque Brunów Palace in Poland from 27th June to 1st July, 2016. DepCoS-RELCOMEX is a series of international conferences organized annually by Department of Computer Engineering of WrocÅ,aw University of Science and Technology since 2006. The roots of the series go as far back as to the seventies of the previous century - the first RELCOMEX conference took place in 1977 - and now its main aim is to promote a multi-disciplinary approach to dependability problems in theory and engineering practice of complex systems. Complex systems, nowadays most often computer-based and distributed, are built upon a variety of technical, information, software and human resources. The challenges in their design, analysis and maintenance not only originate from the involved technical and organizational structures but also from the complexity of the information processes that must be efficiently executed in a diverse, often hostile operational environment. Traditional methods of reliability evaluation focused only on technical resources are usually insufficient in this context and more innovative, multidisciplinary methods of dependability analysis must be applied. The diversity of the topics which need to be considered is well illustrated by the selection of the submissions in these proceedings with their subjects ranging from mathematical models and design methodologies through software engineering and data security issues up to practical problems in technical, e. g. transportation, systems.

Deployable Multimodal Machine Intelligence: Applications in Biomedical Engineering (Lecture Notes in Bioengineering)

by Hongliang Ren

This book highlights the principles, design and characterization of mechanically compliant soft and foldable robots. Traditional rigid robots with bulky footprints and complicated components prolong the design iteration and optimization for keyhole and minimally invasive transluminal applications. Therefore, there is an interest in developing soft and foldable robots with remote actuation, multimodal sensing and machine intelligence. This book discusses the use of foldable and cuttable structures to design biomimetic deployable soft robots, that can exhibit a fair number of motions with consistency and repeatability. It presents the overall design principles, methodology, instrumentation, metamorphic sensing, multi-modal perception, and machine intelligence for creating untethered foldable active structures. These robotic structures can generate a variety of motions such as wave induction, compression, inchworm, peristalsis, flipping, tumbling, walking, swimming, flexion/extension etc. Remote actuation can control motions along regular and irregular surfaces from proximal sides. For self-deployable medical robots, motion diversity and shape reconfiguration are crucial factors. Deployable robots, with the use of malleable and resilient smart actuators, hold this crucial advantage over their conventional rigid robot counterparts. Such flexible structures capable of being compressed and expanded with intelligence perceptions hold enormous potential in biomedical applications.
