The novel finite element formulations fall into the category of geometrically exact Kirchhoff-Love beams. A prominent characteristic of this category is that the absence of shear deformation is strongly enforced by removing two degrees of freedom. Further, the corresponding beam theories exhibit not only translational but also rotational degrees of freedom and their configurations thus form a non-additive and non-commutative space. Sophisticated interpolation schemes are required that need to be tested not only for locking, spatial convergence behavior, and energy conservation, but also for observer invariance and path-independence. For the three novel beam element formulations all these properties are analytically and numerically studied and confirmed, if applicable. Two different rotation parameterization strategies are employed based on the well-known geodesic interpolation used in many Simo-Reissner beams and the lesser known split into the so-called \textit{smallest rotation} and a torsional part. Application of the former parameterization results in a mixed finite element formulation intrinsically free of locking phenomena. Additionally, the first geometrically exact Kirchhoff-Love beam element is presented, which strongly enforces inextensibility by removing another degree of freedom. Furthermore, the numerical efficiency of the new beam formulations is compared to other beam elements that allow for or suppress shear deformation. When modeling very slender beams, the new elements offer distinct numerical advantages.Standard molecular dynamics simulations, which are commonly used to study polymers, suffer from a lack of a careful mathematical basis and the use of an expensive explicit time integration scheme. To circumvent these shortcomings and to be able to simulate stretching experiments on relevant time scales, the problem is described by a stochastic partial differential equation, which can be solved using the finite element method with a backward Euler temporal discretization. In detail, the polymer is represented by a Kirchhoff-Love beam with a linear elastic constitutive model. Inertial and electrostatic forces are neglected. It is deformed by a distributed load mimicking collisions with molecules of the surrounding fluid. Naturally, this load heavily fluctuates over time and space and mean values need to be computed in a Monte Carlo manner. To vastly speed up the fitting process to experimental data in a Bayesian framework, a surrogate model based on a Gaussian process is set up, which directly computes the mean values for given material parameters. The uncertainties and correlations of the material parameters are studied and compared to the literature.
This book explores connections between music, neural activations and brain plasticity, in order to better understand its associated psychological and physiological effects. The final goal is to focus on the positive effects of music to treat neurological disorders, establishing a new co-ordination between different brain areas to improve both mental illness and wellbeing. A secondary goal is to analyse the role of music at a psycho-sociological level, to understand both the transformation of music into a cultural model and the vision of music as an innate instinct.Music is able to create both emotions and volitional processes. The application of new neuroimaging techniques allows us to explore and evaluate with accuracy what happens in our brain during the creative and artistic performance. A wide range of brain regions are recruited for creative tasks, and music has the opportunity to help in enhance and reset some brain pathological disturbances being also able to ameliorate and restore some rhythmic body activities such as sleep, movement and co-ordination.The book represents a valuable and innovative tool both for neurologists as well as healthcare professionals involved in the management of neurological disorders.
This book surveys the foundations of the theory of slice regular functions over the quaternions, introduced in 2006, and gives an overview of its generalizations and applications.As in the case of other interesting quaternionic function theories, the original motivations were the richness of the theory of holomorphic functions of one complex variable and the fact that quaternions form the only associative real division algebra with a finite dimension n>2. (Slice) regular functions quickly showed particularly appealing features and developed into a full-fledged theory, while finding applications to outstanding problems from other areas of mathematics. For instance, this class of functions includes polynomials and power series. The nature of the zero sets of regular functions is particularly interesting and strictly linked to an articulate algebraic structure, which allows several types of series expansion and the study of singularities. Integral representation formulas enrich the theory and are fundamental to the construction of a noncommutative functional calculus. Regular functions have a particularly nice differential topology and are useful tools for the construction and classification of quaternionic orthogonal complex structures, where they compensate for the scarcity of conformal maps in dimension four.This second, expanded edition additionally covers a new branch of the theory: the study of regular functions whose domains are not axially symmetric. The volume is intended for graduate students and researchers in complex or hypercomplex analysis and geometry, function theory, and functional analysis in general.

The text introduces engineering to first-year undergraduate students using Inquiry-Based Learning (IBL). It draws on several different inquiry-based instruction types such as confirmation inquiry, structured inquiry, guided inquiry, and open inquiry, and all of their common elements. Professor Blum¿s approach emphasizes the student¿s role in the learning process, empowering them in the classroom to explore the material, ask questions, and share ideas, instead of the instructor lecturing to passive learners about what they need to know. Beginning with a preface to IBL, the book is organized into three parts, each consisting of four to ten chapters. Each chapter has a dedicated topic where an initial few paragraphs of introductory or fundamental material are provided. This is followed by a series of focused questions that guide the students¿ learning about the concept(s) being taught. Featuring multiple inquiry-based strategies, each most appropriate to the topic, An Inquiry-Based Approach to Introduction to Engineering stands as an easy to use textbook that quickly allows students to actively engage with the content during every class period.

This comprehensive collection brings out the rich and deep philosophical resources of the Zhuangzi. It covers textual, linguistic, hermeneutical, ethical, social/political and philosophical issues, with the latter including epistemological, metaphysical, phenomenological and cross-cultural (Chinese and Western) aspects. The volume starts out with the textual history of the Zhuangzi, and then examines how language is used in the text. It explores this unique characteristic of the Zhuangzi, in terms of its metaphorical forms, its use of humour in deriding and parodying the Confucians, and paradoxically making Confucius the spokesman for Zhuangzi's own point of view. The volume discusses questions such as: Why does Zhuangzi use language in this way, and how does it work? Why does he not use straightforward propositional language? Why is language said to be inadequate to capture the "e;dao"e; and what is the nature of this dao? The volume puts Zhuangzi in the philosophical context of his times, and discusses how he relates to other philosophers such as Laozi, Xunzi, and the Logicians.
This book is intended to provide graduate students and researchers in graph theory with an overview of the elementary methods of graph Ramsey theory. It is especially targeted towards graduate students in extremal graph theory, graph Ramsey theory, and related fields, as the included contents allow the text to be used in seminars. It is structured in thirteen chapters which are application-focused and largely independent, enabling readers to target specific topics and information to focus their study. The first chapter includes a true beginner's overview of elementary examples in graph Ramsey theory mainly using combinatorial methods. The following chapters progress through topics including the probabilistic methods, algebraic construction, regularity method, but that's not all. Many related interesting topics are also included in this book, such as the disproof for a conjecture of Borsuk on geometry, intersecting hypergraphs, Turan numbers and communication channels, etc.
The main purpose of the present book is to develop a general framework for population-based metaheuristics based on some basic concepts of set theory. The idea of the framework is to divide the population of individuals into subpopulations of identical sizes. Therefore, in each iteration of the search process, different subpopulations explore the search space independently but simultaneously. The framework aims to provide a suitable balance between exploration and exploitation during the search process. A few chapters containing algorithm-specific modifications of some state-of-the-art metaheuristics are also included to further enrich the book.The present book is addressed to those scientists, engineers, and students who wish to explore the potentials of newly developed metaheuristics. The proposed metaheuristics are not only applicable to structural optimization problems but can also be used for other engineering optimization applications. The book is likely to be of interest to a wide range of engineers and students who deal with engineering optimization problems.

The book presents contributions including research papers and case studies, providing a comprehensive overview of the field as well as perspectives from related disciplines, such as computer science, biology and material science. The chapter authors were invited speakers at the 8th Design Modelling Symposium "e;Towards Radical Regeneration"e;, which took place at the University of the Arts in Berlin in September 2022.
This book addresses and dissects the roles and crosstalk mechanisms for the 48 human nuclear receptors (NR) in human health and disease. After a State-of-the-Art introduction by an undisputed and celebrated field leader to provide an overview of the field and its significance, chapters are organized into six sections. The first three sections discuss NR roles in Reproduction & Development, Metabolism and Central Systems. These present to the reader our current understanding of NR signaling in the development and functioning of the reproductive system; the roles in the regulation of energy metabolism; and how NR signaling is more widely integrated into systemic functions from calcium flux to circadian rhythm. The subsequent three sections dissect how aberrant NR functions drive Cancer; how new insights into Genomic Interaction are helping to reveal how NR disruption drives disease; and finally, how Translational Efforts are exploiting this understanding from developing novel NR ligands to establishing how underlying genetic variation impacts NR function. Within these sections the chapters also illustrate emerging understanding of how the epigenome and non-coding genome combine to regulate NR function and impact dysfunction. Increasingly these insights cross-fertilize over cell and disease boundaries and it is unsurprising that NR are being explored in novel and new arenas such as the context of neurological disorders and depression. Thus, there is wide scope for re-purposing of licensed drugs and development of new NR-targeting therapies for a host of conditions and diseases. This unique book brings together many of the leading figures in NR research from across the globe, to discuss emerging roles and their implications for human health and disease. It summarizes the state of the art and shows signposts for future research to further shape this influential field.
This book brings together the current theory, research and practical perspectives from different parts of the world on language teacher identity in an attempt to better understand the nature of identities teachers in different contexts develop. By linking theory to pedagogy, the book examines how second language teacher identities are shaped and explores the various links between teacher identities and variables that affect the formation of identities. Theory and Practice in Second Language Teacher Identity includes a foreword by Jack Richards (University of Sydney and RELC), an afterword by Peter de Costa (Michigan State University) and holds 20 invited chapters by established and active scholars and teacher educators to discuss the various aspects of in-service and pre-service second language teacher identity development. It also addresses the way the COVID-19 pandemic has impacted teacher identities and examines under-researched issues, such as the intersection between gender and race in second language teacher identity development and identity construction in second languages other than English.What does it mean to be a teacher of English as a second language in an age of globalization, new media, technological revolution and de-institutionalized knowledge? How do teachers gain pre-service and in-service expertise, a sense of professional identity, and educational integrity? And how have they dealt with the extra-burden imposed by the pandemic? This thought-provoking volume offers valuable perspectives on these important issues in the professional development of English teachers worldwide. - Prof. Claire Kramsch, University of California, Berkeley, USA.The way we see ourselves and are seen by others influences our social and professional interactions. Teacher identity and sense of agency is therefore not merely a matter of research interest for it impacts learners and learning, which makes the topic of this book extremely important. With chapters located in a wide range of countries - from USA to Australia via UAE, Thailand and others - and drawing on a variety of research methods, the book synthesizes extant research and develops many new research avenues. It does so not only with theory in mind but with practical lessons for teachers and teacher educators and thus becomes an essential volume for our libraries and studies. - Prof. Michael Byram, University of Durham, UK.In this compelling collection, co-edited by Karim Sadeghi and Farah Ghaderi, the authors address key questions about language teacher identity in contemporary applied linguistics: What is the relationship between language teacher identity and language teacher agency? To what extent does ideology impact language teacher identity? How do language teachers navigate an increasingly globalized and unequal world? Authors from different regions of the world draw on diverse methodologies to share insightful research on both pre-service and in-service language teacher identity, making an important contribution to applied linguistics and TESOL at a time of great social and educational change. - Prof. Bonny Norton (FRSC), University Killam Professor and Distinguished University Scholar, University of British Columbia, Canada."e;Theory and Practice in Second Language Teacher Identity"e; captures recent thinking about language teacher identity. The broad array of excellent chapter contributions explores multiple dimensions of identity, from teacher agency and emotions to the disruptive effects of the Covid pandemic on teachers' professional lives and practices. The studies draw on a number of theoretical perspectives and demonstrate the use of both familiar and innovative research methodologies. The relevant topics, the up-to-date bibliographic sources, and the useful research findings make this edited volume an essential addition to your bookshelf. - Prof. Gary Barkhuizen, University of Auckland, New Zealand.
This book takes a close look at Shakespeare's engagement with the flurry of controversy and activity surrounding the concept of conversion in post-Reformation England. For playhouse audiences during the period, conversional thought encompassed a markedly diverse, fluid amalgamation of ideas, practices, and arguments centered on the means by which an individual could move from one category of identity to another. In an analysis that includes chapter-length readings of The Taming of the Shrew, Henry IV Part I, The Merchant of Venice, Othello, and The Tempest, the book argues that Shakespearean drama made a unique and substantive intervention in public discourse surrounding conversion, and continues to speak meaningfully about conversional experience for audiences in the present age. It will be of particular benefit to students and scholars with an interest in theatrical history, performance theory, theology, cultural studies, race studies, and gender studies.

Modern AI techniques -- especially deep learning -- provide, in many cases, very good recommendations: where a self-driving car should go, whether to give a company a loan, etc. The problem is that not all these recommendations are good -- and since deep learning provides no explanations, we cannot tell which recommendations are good. It is therefore desirable to provide natural-language explanation of the numerical AI recommendations. The need to connect natural language rules and numerical decisions is known since 1960s, when the need emerged to incorporate expert knowledge -- described by imprecise words like "e;small"e; -- into control and decision making. For this incorporation, a special "e;fuzzy"e; technique was invented, that led to many successful applications. This book described how this technique can help to make AI more explainable.The book can be recommended for students, researchers, and practitioners interested in explainable AI.

In this two-volume compilation of articles, leading researchers reevaluate the success of Hilbert's axiomatic method, which not only laid the foundations for our understanding of modern mathematics, but also found applications in physics, computer science and elsewhere.The title takes its name from David Hilbert's seminal talk Axiomatisches Denken, given at a meeting of the Swiss Mathematical Society in Zurich in 1917. This marked the beginning of Hilbert's return to his foundational studies, which ultimately resulted in the establishment of proof theory as a new branch in the emerging field of mathematical logic. Hilbert also used the opportunity to bring Paul Bernays back to Gottingen as his main collaborator in foundational studies in the years to come.The contributions are addressed to mathematical and philosophical logicians, but also to philosophers of science as well as physicists and computer scientists with an interest in foundations.
This book is mainly intended for residents and young physicians in Nuclear Medicine, Oncology and Gynaecology, as well as other professionals interested in this area. It covers the application of several relevant nuclear medicine procedures for malignancies affecting the female reproductive system and the breast. To date, there has never been a nuclear medicine textbook specifically focused on this topic, which this work seeks to remedy. In recent years, certain nuclear medicine procedures have proven to be extremely valuable for the diagnosis and staging of gynaecological malignancies and breast cancer. The book provides a comprehensive and structured review of these procedures, accompanied by a summary of the respective issues, making it a valuable asset for students, instructors and practitioners alike.
