Paperback. Etat : Very Good. This book presents a cultural perspective on scientific and technological development. As opposed to the story-lines of economic innovation and social construction that tend to dominate both the popular and scholarly literature on science, technology and society (or STS), the authors offer an alternative approach, devoting special attention to the role played by social and cultural movements in the making of science and technology. They show how social and cultural movements, from the Renaissance of the late 15th century to the environmental and global justice movements of our time, have provided contexts, or sites, for mixing scientific knowledge and technical skills from different fields and social domains into new combinations, thus fostering what the authors term a hybrid imagination. Such a hybrid imagination is especially important today, as a way to counter the competitive and commercial hubris that is so much taken for granted in contemporary science and engineering discourses and practices with a sense of cooperation and social responsibility. The book portrays the history of science and technology as an underlying tension between hubris -- literally the ambition to play god on the part of many a scientist and engineer and neglect the consequences - and a hybrid imagination, connecting scientific facts and technological artifacts with cultural understanding. The book concludes with chapters on the recent transformations in the modes of scientific and technological production since the Second World War and the contending approaches to greening science and technology in relation to the global quest for sustainable development. The book is based on a series of lectures that were given by Andrew Jamison at the Technical University of Denmark in 2010 and draws on the authors' many years of experience in teaching non-technical, or contextual knowledge, to science and engineering students. The book has been written as part of the Program of Research on Opportunities and Challenges in Engineering Education in Denmark (PROCEED) supported by the Danish Strategic Research Council from 2010 to 2013. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged.

Paperback. Etat : Very Good. Digital technology has become a defining characteristic of modern life. Almost everyone uses it, we all rely on it, and many of us own a multitude of devices. What is more, we all expect to be able to use these technologies straight out the box. This lecture discusses how we are able to do this without apparent problems. We are able to use digital technology because we have learned to cope with it. To cope is used in philosophy to mean absorbed engagement, that is, we use our smart phones and tablet computers with little or no conscious effort. In human-computer interaction this kind of use is more often described as intuitive. While this, of course, is testament to improved design, our interest in this lecture is in the human side of these interactions. We cope with technology because we are familiar with it. We define familiarity as the readiness to engage with technology which arises from being repeatedly exposed to it-often from birth. This exposure involves the frequent use of it and seeing people all around us using it every day. Digital technology has become as common a feature of our everyday lives as the motor car, TV, credit card, cutlery, or a dozen other things which we also use without conscious deliberation. We will argue that we cope with digital technology in the same way as we do these other technologies by means of this everyday familiarity. But this is only half of the story. We also regularly support or scaffold our use of technology. These scaffolding activities are described as epistemic actions which we adopt to make it easier for us to accomplish our goals. With digital technology these epistemic actions include appropriating it to more closer meet our needs. In summary, coping is a situated, embodied, and distributed description of how we use digital technology. The book has been read, but is in excellent condition.

Paperback. Etat : Very Good. Vascular smooth muscle (VSM) constitutes most of the tunica media in blood vessels and plays an important role in the control of vascular tone. Ca2+ is a major regulator of VSM contraction and is strictly regulated by an intricate system of Ca2+ mobilization and Ca2+ homeostatic mechanisms. The interaction of a physiological agonist with its plasma membrane receptor stimulates the hydrolysis of membrane phospholipids and increases the generation of inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG). IP3 stimulates Ca2+ release from the intracellular stores in the sarcoplasmic reticulum. Agonists also stimulate Ca2+ influx from the extracellular space via voltage-gated, receptor-operated, and store-operated channels. Ca2+ homeostatic mechanisms tend to decrease the intracellular free Ca2+ concentration ([Ca2+]i) by activating Ca2+ extrusion via the plasmalemmal Ca2+ pump and the Na+/Ca2+ exchanger and the uptake of excess Ca2+ by the sarcoplasmic reticulum and possibly the mitochondria. A threshold increase in [Ca2+]i activates Ca2+-dependent myosin light chain (MLC) phosphorylation, stimulates actin-myosin interaction, and initiates VSM contraction. The agonist-induced maintained increase in DAG also activates specific protein kinase C (PKC) isoforms, which in turn cause phosphorylation of cytoplasmic substrates that increase the contractile myofilaments force sensitivity to Ca2+ and thereby enhance VSM contraction. Agonists could also activate Rho kinase (ROCK), leading to inhibition of MLC phosphatase and further enhancement of the myofilaments force sensitivity to Ca2+. The combined increases in [Ca2+]i, PKC and ROCK activity cause significant vasoconstriction and could also stimulate VSM hypertrophy and hyperplasia. The protracted and progressive activation of these processes could lead to pathological vascular remodeling and vascular disease. The book has been read, but is in excellent condition.

Paperback. Etat : Very Good. Increasingly, biomedical scientists and engineers are involved in projects, design, or research and development that involve humans or animals. The book presents general concepts on professionalism and the regulation of the profession of engineering, including a discussion on what is ethics and moral conduct, ethical theories and the codes of ethics that are most relevant for engineers. An ethical decision-making process is suggested. Other issues such as conflicts of interest, plagiarism, intellectual property, confidentiality, privacy, fraud, and corruption are presented. General guidelines, the process for obtaining ethics approval from Ethics Review Boards, and the importance of obtaining informed consent from volunteers recruited for studies are presented. A discussion on research with animals is included. Ethical dilemmas focus on reproductive technologies, stem cells, cloning, genetic testing, and designer babies. The book includes a discussion on ethics and the technologies of body enhancement and of regeneration. The importance of assessing the impact of technology on people, society, and on our planet is stressed. Particular attention is given to nanotechnologies, the environment, and issues that pertain to developing countries. Ideas on gender, culture, and ethics focus on how research and access to medical services have, at times, been discriminatory towards women. The cultural aspects focus on organ transplantation in Japan, and a case study of an Aboriginal child in Canada; both examples show the impact that culture can have on how care is provided or accepted. The final section of the book discusses data collection and analysis and offers a guideline for honest reporting of results, avoiding fraud, or unethical approaches. The appendix presents a few case studies where fraud and/or unethical research have occurred. The book has been read, but is in excellent condition.

Paperback. Etat : Very Good. Proprotein convertases (PCs) are a family of proteases including PC1, PC2, Furin, PC4, PACE4, PC5, and PC7. These enzymes are involved in the maturation of many precursor proteins involved in the process of tumorigenesis and metastasis. Since their discovery, PCs were suggested as potential targets for anti-cancer therapy, and their activity was found to directly affect tumor cell proliferation, migration invasion, and the malignant phenotypes of tumor cells. Here, we discuss a number of previous and recent findings on the PCs features, their implication in the regulation of multiple cellular functions that impact on the invasive/metastatic potential of cancer cells, and their clinical relevance in cancer patients. Among the substrates of the proprotein convertases, various growth factors, their receptors, adhesion molecules, and proteases were identified. The PCs are inhibited by endogenous and exogenous inhibitors. To date, only pro7B2, a specific chaperone of PC2, and the granine-like precursor of neuroendocrine protein proSAAS, a selective ligand of PC1, have been identified as endogenous inhibitors of the PCs found in the regulated pathway. However, only PCs prosegments, several bioengineered inhibitors, peptides, and non-peptide compounds were found to inhibit the activity of the PCs found in the secretory pathway.

Paperback. Etat : Very Good. The gastrointestinal mucosal defense system serves to minimize mucosal injury by either ingested or endogenously produced noxious substances. The mucosal defense system is stratified into pre-epithelial (alkaline mucus), epithelial (dynamic epithelial lining), and post-epithelial (microcirculation) components. The mucus lining the epithelial surface presents a diffusional barrier to ingested material (e.g., lipids) and also serves as an unstirred layer in which a pH gradient can be established to prevent acid-induced injury. The epithelial lining prevents entrance of any toxic material to the interstitium and, should it be damaged, it is rapidly resealed by migration of adjacent viable epithelial cells to cover the defect. Any acid or other material that has entered the interstitium is washed out by an intense neurogenic hyperemia. In general, the mucosal defense system is quite effective and any adverse gastrointestinal effects associated with the normal course of nutrient assimilation are minimal. However, there are two situations in which the mucosal defense system is known to be ineffective and result in gastric mucosal injury: inadvertent ingestion of H. pylori. or intentional ingestion of NSAIDs. H. pylori can penetrate the mucus layers and cause epithelial injury and inflammation, while at the same time preventing its clearance by the host immune system. NSAIDs weaken the mucus layer and cause epithelial cell injury. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting.

Paperback. Etat : Very Good. Reactive oxygen species (ROS) influence various physiological processes including host defense, hormone biosynthesis, and cellular signaling. Increased ROS production (oxidative stress) is implicated in many diseases of the cardiovascular system, including hypertension, atherosclerosis, cardiac failure, stroke, diabetes, and kidney disease. ROS are produced throughout the cardiovascular system, in the kidney and central and peripheral nervous system. A major source for cardiovascular, renal, and neural ROS is a family of non-phagocytic NAD(P)H oxidases, including the prototypic Nox2 homologue-based NAD(P)H oxidase, as well as other NAD(P)H oxidases, such as Nox1 and Nox4. Other possible sources include mitochondrial electron transport enzymes, xanthine oxidase, cyclooxygenase, lipoxygenase, and uncoupled nitric oxide synthase (NOS). NAD(P)H oxidase-derived ROS is important in regulating endothelial function and vascular tone and oxidative stress is implicated in endothelial dysfunction, inflammation, hypertrophy, apoptosis, migration, fibrosis, angiogenesis and rarefaction, important processes involved in vascular remodeling in cardiovascular disease. These findings have evoked considerable interest because of the possibilities that therapies targeted against non-phagocytic NAD(P)H oxidase to decrease ROS generation and/or strategies to increase nitric oxide (NO) availability and antioxidants may be useful in minimizing vascular injury and thereby prevent or regress target organ damage associated with hypertension and other cardiovascular diseases.

Paperback. Etat : Very Good. One of the application areas of data mining is the World Wide Web (WWW or Web), which serves as a huge, widely distributed, global information service for every kind of information such as news, advertisements, consumer information, financial management, education, government, e-commerce, health services, and many other information services. The Web also contains a rich and dynamic collection of hyperlink information, Web page access and usage information, providing sources for data mining. The amount of information on the Web is growing rapidly, as well as the number of Web sites and Web pages per Web site. Consequently, it has become more difficult to find relevant and useful information for Web users. Web usage mining is concerned with guiding the Web users to discover useful knowledge and supporting them for decision-making. In that context, predicting the needs of a Web user as she visits Web sites has gained importance. The requirement for predicting user needs in order to guide the user in a Web site and improve the usability of the Web site can be addressed by recommending pages to the user that are related to the interest of the user at that time. This monograph gives an overview of the research in the area of discovering and modeling the users' interest in order to recommend related Web pages. The Web page recommender systems studied in this monograph are categorized according to the data mining algorithms they use for recommendation. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged.

Paperback. Etat : Very Good. Face detection, because of its vast array of applications, is one of the most active research areas in computer vision. In this book, we review various approaches to face detection developed in the past decade, with more emphasis on boosting-based learning algorithms. We then present a series of algorithms that are empowered by the statistical view of boosting and the concept of multiple instance learning. We start by describing a boosting learning framework that is capable to handle billions of training examples. It differs from traditional bootstrapping schemes in that no intermediate thresholds need to be set during training, yet the total number of negative examples used for feature selection remains constant and focused (on the poor performing ones). A multiple instance pruning scheme is then adopted to set the intermediate thresholds after boosting learning. This algorithm generates detectors that are both fast and accurate. We then present two multiple instance learning schemes for face detection, multiple instance learning boosting (MILBoost) and winner-take-all multiple category boosting (WTA-McBoost). MILBoost addresses the uncertainty in accurately pinpointing the location of the object being detected, while WTA-McBoost addresses the uncertainty in determining the most appropriate subcategory label for multiview object detection. Both schemes can resolve the ambiguity of the labeling process and reduce outliers during training, which leads to improved detector performances. In many applications, a detector trained with generic data sets may not perform optimally in a new environment. We propose detection adaption, which is a promising solution for this problem. We present an adaptation scheme based on the Taylor expansion of the boosting learning objective function, and we propose to store the second order statistics of the generic training data for future adaptation. We show that with a small amount of labeled data in the new environment, the detector's performance can be greatly improved. We also present two interesting applications where boosting learning was applied successfully. The first application is face verification for filtering and ranking image/video search results on celebrities. We present boosted multi-task learning (MTL), yet another boosting learning algorithm that extends MILBoost with a graphical model. Since the available number of training images for each celebrity may be limited, learning individual classifiers for each person may cause overfitting. MTL jointly learns classifiers for multiple people by sharing a few boosting classifiers in order to avoid overfitting. The second application addresses the need of speaker detection in conference rooms. The goal is to find who is speaking, given a microphone array and a panoramic video of the room. We show that by combining audio and visual features in a boosting framework, we can determine the speaker's position very accurately. Finally, we offer our thoughts on future directions for face detection. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting.

Paperback. Etat : Very Good. The motivation for developing this synthesis lecture was to provide a tutorial on queuing and trunking, with extensions to networks of queues, suitable for supplementing courses in communications, stochastic processes, and networking. An essential component of this lecture is MATLAB-based demonstrations and exercises, which can be easily modified to enable the student to observe and evaluate the impact of changing parameters, arrival and departure statistics, queuing disciplines, the number of servers, and other important aspects of the underlying system model. Much of the work in this lecture is based on Poisson statistics, since Poisson models are useful due to the fact that Poisson models are analytically tractable and provide a useful approximation for many applications. We recognize that the validity of Poisson statistics is questionable for a number of networking applications and therefore we briefly discuss self-similar models and the Hurst parameter, long-term dependent models, the Pareto distribution, and other related topics. Appropriate references are given for continued study on these topics. The initial chapters of this book consider individual queues in isolation. The systems studied consist of an arrival process, a single queue with a particular queuing discipline, and one or more servers. While this allows us to study the basic concepts of queuing and trunking, modern data networks consist of many queues that interact in complex ways. While many of these interactions defy analysis, the final chapter introduces a model of a network of queues in which, after being served in one queue, customers may join another queue. The key result for this model is known as Jackson's Theorem. Finally, we state the BCMP Theorem, which can be viewed as a further extension of Jackson's Theorem and present Kleinrock's formula, which can be viewed as the network version of Little's Theorem.

Paperback. Etat : Very Good. As speech processing devices like mobile phones, voice controlled devices, and hearing aids have increased in popularity, people expect them to work anywhere and at any time without user intervention. However, the presence of acoustical disturbances limits the use of these applications, degrades their performance, or causes the user difficulties in understanding the conversation or appreciating the device. A common way to reduce the effects of such disturbances is through the use of single-microphone noise reduction algorithms for speech enhancement. The field of single-microphone noise reduction for speech enhancement comprises a history of more than 30 years of research. In this survey, we wish to demonstrate the significant advances that have been made during the last decade in the field of discrete Fourier transform domain-based single-channel noise reduction for speech enhancement. Furthermore, our goal is to provide a concise description of a state-of-the-art speech enhancement system, and demonstrate the relative importance of the various building blocks of such a system. This allows the non-expert DSP practitioner to judge the relevance of each building block and to implement a close-to-optimal enhancement system for the particular application at hand.

Paperback. Etat : new. Paperback. Light field is one of the most representative image-based rendering techniques that generate novel virtual views from images instead of 3D models. The light field capture and rendering process can be considered as a procedure of sampling the light rays in the space and interpolating those in novel views. As a result, light field can be studied as a high-dimensional signal sampling problem, which has attracted a lot of research interest and become a convergence point between computer graphics and signal processing, and even computer vision.This lecture focuses on answering two questions regarding light field sampling, namely how many images are needed for a light field, and if such number is limited, where we should capture them. The book can be divided into three parts.First, we give a complete analysis on uniform sampling of IBR data. By introducing the surface plenoptic function, we are able to analyze the Fourier spectrum of non-Lambertian and occluded scenes. Given the spectrum, we also apply the generalized sampling theorem on the IBR data, which results in better rendering quality than rectangular sampling for complex scenes. Such uniform sampling analysis provides general guidelines on how the images in IBR should be taken. For instance, it shows that non-Lambertian and occluded scenes often require a higher sampling rate.Next, we describe a very general sampling framework named freeform sampling. Freeform sampling handles three kinds of problems: sample reduction, minimum sampling rate to meet an error requirement, and minimization of reconstruction error given a fixed number of samples. When the to-be-reconstructed function values are unknown, freeform sampling becomes active sampling. Algorithms of active sampling are developed for light field and show better results than the traditional uniform sampling approach.Third, we present a self-reconfigurable camera array that we developed, which features a very efficient algorithm for real-time rendering and the ability of automatically reconfiguring the cameras to improve the rendering quality. Both are based on active sampling. Our camera array is able to render dynamic scenes interactively at high quality. To the best of our knowledge, it is the first camera array that can reconfigure the camera positions automatically. Focuses on answering two questions regarding light field sampling, namely how many images are needed for a light field, and if such number is limited, where we should capture them. The book gives a complete analysis on uniform sampling of IBR data; describes a very general sampling framework named freeform sampling; and presents a self-reconfigurable camera array that the authors developed.
