Local Pattern Detection ; International Seminar Dagstuhl Castle, Germany, April 12-16, 2004, Revised Selected Papers

Introduction The dramatic increase in available computer storage capacity over the last 10 years has led to the creation of very large databases of scienti?c and commercial information. The need to analyze these masses of data has led to the evolution of the new field knowledge discovery in databases (KDD) at the intersection of machine learning, statistics and database technology. Being interdisciplinary by nature, the field offers the opportunity to combine the expertise of different fields into a common objective. Moreover, within each field diverse methods have been developed and justified with respect to different quality criteria. We have to investigate how these methods can contributet o solving the problem of KDD. Traditionally, KDD was seeking to end global models for the data that - plain most of the instances of the database and describe the general structure of the data. Examples are statistical time series models, cluster models, logic programs with high coverageor classi?cation models like decision trees or linear decision functions. In practice, though, the use of these models often is very l- ited, because global models tend to end only the obvious patterns in the data, 1 which domain experts already are aware of . What is really of interest to the users are the local patterns that deviate from the already-known background knowledge. David Hand, who organized a workshop in 2002, proposed the new field of local patterns.

Liver MRI : Correlation with other Imaging Modalities and Histopathology

In this seminal manuscript the - thor described a new imaging technique which moved the single dimension of NMR spectroscopy to the dual dimension of spatial orientation, thereby resulting in the foundation of modern magnetic re- nance (MR) imaging. Over the ensuing years, MR imaging has assumed an increasingly important role in clinical imaging. It distinguishes itself from other imaging modalities, such as ultrasound (US) or computed tomography (CT), by the unique ability to visualize specific tissue components in a non-- vasive manner. In the earlier days, diagnostic MR imaging was limited to cerebral and musculoskeletal diseases. - aging of other areas which are more prone to movement through breathing (abdominal) or pulsation motions (cardiac) became available more recently, with the introduction of faster sequences and the - velopment of more dedicated MR imaging coils.

Lipids in Health and Disease

Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.

Linear Systems Control : Deterministic and Stochastic Methods

Modern control theory and in particular state space or state variable methods can be adapted to the description of many different systems because it depends strongly on physical modeling and physical intuition. The laws of physics are in the form of differential equations and for this reason, this book concentrates on system descriptions in this form. This means coupled systems of linear or nonlinear differential equations. The physical approach is emphasized in this book because it is most natural for complex systems. It also makes what would ordinarily be a difficult mathematical subject into one which can straightforwardly be understood intuitively and which deals with concepts which engineering and science students are already familiar.

Limnology and Aquatic Birds ; Proceedings of the Fourth Conference Working Group on Aquatic Birds of Societas Internationalis Limnologiae (SIL), Sackville, New Brunswick, Canada, August 3-7, 2003

The importance of habitat conservation for the protection of birds has become widely acknowledged and accepted by natural resource managers and the general public. Papers presented in this volume further our understanding of the important role that limnology has in determining habitat suitability for waterbirds. Long-term population monitoring of waterbirds is an important tool in our quest to understand the role waterbirds play in their environment. Continued population declines of many species of aquatic birds indicate the need for additional understanding of how human activities negatively impact water quality and bird populations and what mitigative actions can be taken. The main objective of the Working Group on Aquatic Birds of the International Limnological Society (SIL) is to integrate waterbirds into hydrobiology and treat waterbird studies in a limnological context. To achieve this goal, the Working Group organizes conferences to facilitate communications among limnologists interested in aquatic birds and ornithologists interested in the aquatic habitat. The efforts of the SIL Working Group on aquatic birds has resulted in a new emphasis on the links between aquatic birds and their environment

Light Scattering by Optically Soft Particles: Theory and Applications

Deals with a particular class of approximation methods in the context of light scattering by small particles. This class of approximations has been termed as eikonal or soft particle approximations. The eikonal approximation was studied extensively in the potential scattering and then adopted in optical scattering problems. In this context, the eikonal and other soft particle approximations pertain to scatterers whose relative refractive index compared to surrounding medium is close to unity. The study of these approximations is very important because soft particles occur abundantly in nature. For example, the particles that occur in ocean optics, biomedical optics, atmospheric optics and in many industrial applications can be classified as soft particles. This book was written in recognition of the long-standing and current interest in the field of scattering approximations for soft particles. It should prove to be a useful addition for researchers in the field of light scattering.

Lifelong Learning - Signs, Discourses, Practices

This text explores the different ways in which the various social practices in which people participate becomes signed as learning, how and why that occurs and with what consequences. It takes seriously the linguistic turn in social theory to draw upon semiotics and poststructuralism through which to explore the significance of lifelong learning as an emerging discourse in education. The text explores the different ways in which learning conveys meaning and is given meaning. Given this, lifelong learning therefore is a way, and a significant way, in which learning is fashioned. The text then explores the notion that, if learning is lifelong and lifewide, what precisely is learning as distinct from other social practices and how those practices are given meaning as learning.

Level Crossing Methods in Stochastic Models

Since its inception in 1974, the level crossing approach for analyzing a large class of stochastic models has become increasingly popular among researchers. This volume traces the evolution of level crossing theory for obtaining probability distributions of state variables and demonstrates solution methods in a variety of stochastic models including: queues, inventories, dams, renewal models, counter models, pharmacokinetics, and the natural sciences. Results for both steady-state and transient distributions are given, and numerous examples help the reader apply the method to solve problems faster, more easily, and more intuitively.

Les techniques de monitorage hémodynamique en réanimation = Hemodynamic monitoring techniques in intensive care

The hemodynamic monitoring of intensive care patients is undergoing major changes. Technological advances such as computerization and miniaturization have made it possible to considerably expand the range of assessment tools available at the bedside. Thus, the approach to cardiovascular monitoring - which was once readily "invasive" and global - is gradually becoming non-invasive and locoregional or even tissue. At the same time, the combined evolution of technology and physiological and pathophysiological concepts now provides the clinician with access to a variety of "functional hemodynamic monitoring". The aim of this book is to provide a better understanding of the interest and the limits of the hemodynamic parameters accessible by current hemodynamic monitoring techniques. It thus aims to ensure that the use of these techniques is perfectly mastered by resuscitators and anesthetists-resuscitators so that patient care is ultimately optimal.

Les prothèses tricompartimentaires du genou de première intention : Techniques opératoires. Problèmes et solutions = Primary tricompartmental knee replacement : Surgical techniques, problems, and solutions

It seems difficult and presumptuous to want to write a book on total knee replacement. There are many quality works dealing with this subject. The knee prosthesis has, from its origin, particularly in the United States, given rise to considerable studies in all directions: biomechanical, physiological, biological and industrial. Our goal is to offer the youngest a book of simple knowledge without pretension of completeness or prejudice as to long debated subjects (conservation or not of the posterior cruciate ligament, cement or without cement, resurfacing or not of the patella, fixed plate or mobile platform, etc.), and to give practical advice based on our experience. Why limit yourself to first-line tricompartmentals? Because it is the most common solution to the usual degenerative knee problems. In addition, unicompartment and revision prostheses will be the subject of further literature. Everyone knows that to put a knee prosthesis model, and therefore to a system. However, it is important to be able to keep your freedom of analysis in order to maintain your freedom of choice. You have to know how to put on a knee prosthesis without compromise or fanaticism. Convictions are more dangerous enemies of truth than lies. Nietzsche

Les infections urinaires = Urinary tract infections

Les Infections urinaires provides an update on knowledge concerning the epidemiology of community-based infection, on the mechanisms of bacterial resistance and on certain aspects of the disease useful to urologists as well as infectious diseases, gynecologists, emergency physicians and attending physicians. . Nosocomial urinary tract infection is approached from the perspective of risk factors. Acute and chronic prostatitis was the subject of a consensus conference supported by the World Health Organization within the framework of the International Consensus Conferences in Urology in Paris. The full text and the recommendations are reported with the consent of their authors. This book is an author's book and not an author's book because urinary tract infection is multiple, complex and justifies a multidisciplinary approach.

Les infections intra-abdominales aiguës = Acute intra-abdominal infections

Paradoxically, serious intra-abdominal infections are the forgotten ones in the world of infectious diseases. Paradoxical, because they are very common pathologies, affecting all age groups of the population and often life-threatening; paradoxical, because they concern many medical specialties through intensive care, gastroenterology, hepatology, imaging, infectious diseases, emergencies and surgery. Hence the need, thanks to an interdisciplinary collaboration, to publish a book in French bringing together all infectious abdominal pathologies, thus offering a synthesis of recent data from the literature in this field. This document should allow the various specialties concerned to find updates integrating the latest clinical, diagnostic and therapeutic data. Specialty interns and practitioners in the field will find something to establish an effective and up-to-date strategy for the management of patients with these pathologies, the high incidence of which and the severity of which is too often overlooked, it is important to remember.

Learning Theory ; Vol. 3559 : 18th Annual Conference on Learning Theory, COLT 2005, Bertinoro, Italy, June 27-30, 2005, Proceedings

The technical program contained 45 papers selected from 120 submissions, 3 open problems selected from among 5 contributed, and 2 invited lectures. The invited lectures were given by Sergiu Hart on “Uncoupled Dynamics and Nash Equilibrium”, and by Satinder Singh on “Rethinking State, Action, and Reward in Reinforcement Learning”. These papers were not included in this volume. The Mark Fulk Award is presented annually for the best paper co-authored by a student. The student selected this year was Hadi Salmasian for the paper titled “The Spectral Method for General Mixture Models” co-authored with Ravindran Kannan and Santosh Vempala. The number of papers submitted to COLT this year was exceptionally high. In addition to the classical COLT topics, we found an increase in the number of submissions related to novel classi?cation scenarios such as ranking. This - crease re?ects a healthy shift towards more structured classi?cation problems, which are becoming increasingly relevant to practitioners.

Learning and Adaption in Multi-Agent Systems ; 1st International Workshop, LAMAS 2005, Utrecht, The Netherlands, July 25, 2005, Revised Selected Papers

Contains selected and revised papers of the International Workshop on Lea- ing and Adaptation in Multi-Agent Systems (LAMAS 2005), held at the AAMAS 2005 Conference in Utrecht, The Netherlands, July 26. An important aspect in multi-agent systems (MASs) is that the environment evolves over time, not only due to external environmental changes but also due to agent int- actions. For this reason it is important that an agent can learn, based on experience, and adapt its knowledge to make rational decisions and act in this changing environment autonomously. Machine learning techniques for single-agent frameworks are well established. Agents operate in uncertain environments and must be able to learn and act - tonomously. This task is, however, more complex when the agent interacts with other agents that have potentially different capabilities and goals. The single-agent case is structurally different from the multi-agent case due to the added dimension of dynamic interactions between the adaptive agents. Multi-agent learning, i.e., the ability of the agents to learn how to cooperate and compete, becomes crucial in many domains. Autonomous agents and multi-agent systems (AAMAS) is an emerging multi-disciplinary area encompassing computer science, software engineering, biology, as well as cognitive and social sciences. A t- oretical framework, in which rationality of learning and interacting agents can be - derstood, is still under development in MASs, although there have been promising ?

Lean Brain Management : More Success and Efficiency by Saving Intelligence

Intelligence is wasted on problems that themselves have been caused by an excess of intelligence. Lean Brain Management strives toward uncompromising Lean Brain Quality. Lean Brain stands for consistent economization of intelligence in all realms of life: Intelligent systems will only be operated by unskilled workers. Education, universities, and schools would become obsolete. A week of training would be enough for virtually any job. ("You are now the physician for the measles in the State of Ohio. In response to phone calls, send this prescription.") Lean Brain is not aimed at dumbing down! Lean Brain can survive on just a very small amount of central intelligence. Potential savings amount to trillions! This is demonstrated using Germany as an example. With this book, Dueck presents a radical suggestion for world improvement. The desire to laugh infinitely about it will eventually segue into a collective rude awakening. The book contains concrete advice for managers to economize on intelligence, and is thus--in keeping with the theme--written in an easy-to-read fashion.

Law and the Semantic Web : Legal Ontologies, Methodologies, Legal Information Retrieval, and Applications

As part of this objective, ICT (information and communication technologies) services should become available for every citizen, and for all schools, homes and businesses. The book you have in front of you is about Semantic Web technology and law. Law is something omnipresent; all citizens — at some points in their lives — have to deal with it. In addition, law involves a large group of professionals, and is a mul- billion business world wide. Information technology is important because it that can improve citizens’ interaction with law, as well as improve legal professionals’ work environment. Legal professionals dedicate a significant amount of their time to finding, reading, analyzing and synthesizing information in order to take decisions, and prepare advice and trials, among other tasks. As part of the “Semantic-Based Knowledge and Content Systems” Strategic Objective, the European Commission is funding projects to construct technology to make the Semantic Web vision come true. 1 The articles in this book are related to two current foci of the Strategic Objective : • Knowledge acquisition and modelling, capturing knowledge from raw information and multimedia content in webs and other distributed repositories to turn poorly structured information into machi- processable knowledge.

Lattice Hadron Physics

This series of lectures draws upon the developments made in recent years in implementing chirality on the lattice via the overlap formalism. These developments exploit chiral effective field theory in order to extrapolate lattice results to physical quark masses, new forms of improving operators to remove lattice artefacts, analytical studies of finite volume effects in hadronic observables, and state-of-the-art lattice calculations of excited resonances. This volume is designed to assist those outside the field who want quickly to becoming literate in these topics. So it is intended for graduate students and experienced researchers in other areas of hadronic physics to provide the background through which they can appreciate, if not become active in, contemporary lattice gauge theory and its applications to hadronic phenomena.

Laser in restorative dentistry

The application of lasers in restorative dentistry has revolutionized dental treatments, offering enhanced precision, reduced discomfort, and improved clinical outcomes. Lasers have become a valuable tool in procedures such as cavity preparation, caries removal, tooth whitening, and composite resin curing. Their ability to selectively target diseased tissue while preserving healthy structures minimizes trauma and promotes faster healing. Moreover, lasers offer a less invasive alternative to traditional mechanical methods, often eliminating the need for anesthesia. This technology's versatility allows for its use in both hard and soft tissue treatments, including gingival recontouring and managing peri-implant diseases. As laser technology continues to advance, its integration into restorative dental practices offers significant potential for improved patient care, greater procedural efficiency, and long-term durability of restorations. Future developments in laser applications are expected to expand their role, making them an indispensable asset in modern dentistry.
