Quantitative Susceptibility Mapping gives a systematic account of the fundamentals of physical concepts, technical algorithms, and biomedical applications associated with magnetic resonance imaging of tissue magnetism. Recent progresses in MRI phase analyses and in numerical optimization solvers of inverse problems and promising applications in studying iron and oxygen metabolisms and hemorrhage have attracted many people to investigate quantitative susceptibility mapping (QSM). The objective of this book is to provide a comprehensive and timely introduction for the newly formed and rapidly growing QSM community. Emphasis has been placed on clarity throughout the narrative. Detailed considerations are presented to clarify the subtleties of the physics of magnetism and magnetic resonance signals: - Thorough demonstrations of the forward problem from magnetic susceptibility to field. - Comprehensive descriptions of major approaches to solving the field to susceptibility inverse problem. - Specific examples of clinical and scientific applications. Engineers, physicists, and clinicians at all levels, from students to established investigators, will find Quantitative Susceptibility Mapping a useful aid in understanding the physical principles of magnetic resonance imaging of tissue magnetic properties.

Principles of Magnetic Resonance Imaging provides a contemporary introduction to the fundamental concepts of MRI, applies these concepts in biomedical applications, and relates these concepts to the latest MRI developments. A unified approach based on spin phase factor averaging is supplied to connect microscopic molecular processes with macroscopic MRI contrasts: relaxation, transport and magnetism. Graphic illustrations of Bloch Equation solutions and various biophysical processes are presented for visualizing abstract ideas. Simplified calculations and specific examples are given for precise appreciation of fundamental concepts. Insightful interpretations and clinical examples are furnished for exemplifying biomedical information in MRI. This book contains three parts: I. Section the body into voxels. Part I describes the Fourier encoding matrix for imaging, its realization in magnetic resonance (MR) using gradient fields, and k-space sampling.II. What's in a voxel? Part II examines the effects of biophysical processes on MRI voxel signal. Spin phase factor averaging over the observation time and voxel space is provided as a unified biophysical model for explaining major MRI contrasts: Proton-proton interaction in a short range defined by local cellular contents (relaxation) causes T2 signal decay and T1 energy loss.Proton motion (transport) including diffusion, perfusion, flow and biomechanical motion can be measured as a phase contrast or signal decay using a gradient field.Electron-proton interaction (magnetism: nonlocal effects of magnetic susceptibility and local effects of chemical shift) can be quantitatively analyzed from MRI signal phase.The connection of MRI contrast physics to tissue molecular contents is conceptualized in the following three terms: 1) cellularity for T2 weighted imaging and diffusion weighted imaging (the latter emphasizing cellular geometry), 2) vascularity for T1 weighted imaging with Gadolinium injection, MR perfusion, and MR angiography, and 3) biomolecularity for MR spectroscopy and magnetic susceptibility imaging.III. How to operate an MRI machine? Part III describes MRI safety issues, hardware, software including advanced imaging methods, MRI scanning, and routine MRI protocols.As examples of applying basic physics concepts, this MRI book further illustrates the latest technological innovations, including: B_(1+)and B_(1-) mapping; Chemical exchange saturation transfer (CEST); Electric property tomography (EPT); Magnetic particle imaging (MPI); MR elastography (MRE); Moving spin tagging including ASL, SPAMM and DENSE; Navigator motion compensation; Parallel or accelerated imaging including SENSE, GRAPPA, compressed sensing and other Bayesian approaches; Quantitative susceptibility mapping (QSM)

Introductory Medicine for Engineers provides a concise introduction of the basic concepts of clinical medicine and hospital culture to engineers. This book aims to bridge the gap between engineering discipline and medical practice, so that engineers may feel confident in working with medical professionals to advance healthcare technology. This book is largely developed from the Clinical Summer Immersion Program for Biomedical Engineering PhD Students at Cornell University, which the author has been directing for the past decade. Introductory descriptions of medicine and medical practice covered in this book include - General cultures and customs of a hospital - Medical terminology - Diagnosis based on medical imaging - Surgical devices and basic surgical treatment - Process of medicine - Basics of pharmaceuticals

This book analyzes the social, economic, and political impact of Han Chinese migration into the borderlands that became Inner Mongolia during the Qing period. Linking local history to global movements, Yi Wang traces Inner Mongolia's integration into what would become the nation-state of China and from there into a global capitalist economy.

Does the language we speak affect the way we think? This Element provides a synthesis of contemporary research on the interplay between language and cognition in speakers of two or more languages and examines variables deemed to impact bilingual acquisition and conceptualization of language-specific thinking patterns during L2 learning. An overview of different yet interrelated studies is offered across a variety of conceptual domains to illustrate different approaches and key variables. The comparison of monolingual and bilingual data demonstrates the highly integrative nature between L2 learning and the changing of one's entire cognitive outlook in L2 speakers. This Element makes relevant connections between language learning and bilingual cognition, aiming to shed new light on how learners acquire conceptual distinctions of the target language(s). It also raises theoretical and pedagogical issues that encourage teachers to reflect upon how to incorporate recent advances in language-and-cognition research with aspects of L2 teaching.

This unique and comprehensive introduction offers an unrivalled and in-depth understanding of the computational-based thermodynamic approach and how it can be used to guide the design of materials for robust performances, integrating basic fundamental concepts with experimental techniques and practical industrial applications, to provide readers with a thorough grounding in the subject. Topics covered range from the underlying thermodynamic principles, to the theory and methodology of thermodynamic data collecting, analysis, modeling, and verification, with details on free energy, phase equilibrium, phase diagrams, chemical reactions, and electrochemistry. In thermodynamic modelling, the authors focus on the CALPHAD method and first-principles calculations. They also provide guidance for use of YPHON, a mixed-space phonon code developed by the authors for polar materials based on the supercell approach. Including worked examples, case studies, and end-of-chapter problems, this is an essential resource for students, researchers, and practitioners in materials science.
