Elastic Waves: High Frequency Theory (Chapman & Hall/CRC Monographs and Research Notes in Mathematics)
by Vassily Babich Aleksei KiselevElastic Waves: High Frequency Theory is concerned with mathematical aspects of the theory of high-frequency elastic waves, which is based on the ray method. The foundations of elastodynamics are presented along with the basic theory of plane and spherical waves. The ray method is then described in considerable detail for bulk waves in isotropic and anisotropic media, and also for the Rayleigh waves on the surface of inhomogeneous anisotropic elastic solids. Much attention is paid to analysis of higher-order terms and to generation of waves in inhomogeneous media. The aim of the book is to present a clear, systematic description of the ray method, and at the same time to emphasize its mathematical beauty. Luckily, this beauty is usually not accompanied by complexity and mathematical ornateness.

Elder Abuse in the LGBTQ2SA+ Community: The Impact of Homophobia and Transphobia (International Perspectives on Aging #37)
by Gloria Gutman Claire Robson Jen Marchbank Makaela PrenticeThis book describes and analyzes the lived experience of elder abuse from the queer community. It discusses the experiences by transwomen, gay men and lesbians of financial abuse, physical and sexual abuse, homophobic abuse, and neglect within partner relationships, residential care, in home care, and religious organizations. Queer and trans elders have been described as ‘The Silent Generation’, since they have lived through times when their sexual and gender identities were criminalized and pathologized. The book shows that they are far more at risk to suffer abuse and neglect by those they should be able to trust, since they are more likely to have encountered all key risk factors, such as isolation, previous abuse and trauma, and mistrust of the health care system. Their vulnerability has been overlooked and this book addresses that gap. As such, this book provides a great resource to anyone working with elders, including medical professionals, care providers, police, counsellors, and policy makers.
Eldercare Labor Demand in China and Coping Strategies
by Yali ZhuThis book employs Markov models and propensity score matching methods to analyze the demand for elderly care labor, utilizing data from the China Longitudinal Healthy Longevity Survey (CLHLS) and World Population Prospects 2022 (United Nations, 2022). The model predicts the health transferring scenario among the aging population firstly, and then the demand for elderly care labor from 2022 to 2058 under a fixed care time demand scenario according to 8-hour working system, as well as national and provincial regulations on caregiver-carereceiver ratios. The accelerated aging process and rapid increase in the younger elderly population will result in a rapid increase in the demand for elderly care labor for the healthy elderly until about 2042, with a 1.5-fold increase. This is followed by accelerated growth in the demand for elderly care labor for the impaired and dysfunctional aging population. Over time, the supply of older adults without care will gradually increase, nearly doubling by 2058 compared to 2022. It is recommended that on the one hand, eldercare labor demand in China can be reduced from the origin by improving the health of the population; and on the other hand, the effective supply of elderly care be expanded by building a modern care service system, improving relevant policies, integrating care resources, and innovating the supply model.

Electrically Driven Quantum Dot Based Single-Photon Sources: Modeling and Simulation (Springer Theses)
by Markus KantnerSemiconductor quantum optics is on the verge of moving from the lab to real world applications. When stepping from basic research to new technologies, device engineers will need new simulation tools for the design and optimization of quantum light sources, which combine classical device physics with cavity quantum electrodynamics. This thesis aims to provide a holistic description of single-photon emitting diodes by bridging the gap between microscopic and macroscopic modeling approaches. The central result is a novel hybrid quantum-classical model system that self-consistently couples semi-classical carrier transport theory with open quantum many-body systems. This allows for a comprehensive description of quantum light emitting diodes on multiple scales: It enables the calculation of the quantum optical figures of merit together with the simulation of the spatially resolved current flow in complex, multi-dimensional semiconductor device geometries out of one box. The hybrid system is shown to be consistent with fundamental laws of (non-)equilibrium thermodynamics and is demonstrated by numerical simulations of realistic devices.

Electricity and Magnetism: New Formulation by Introduction of Superconductivity (Undergraduate Lecture Notes in Physics)
by Teruo MatsushitaThis comprehensive textbook covers electricity and magnetism in great depth, with the 3rd edition offering updated descriptions of electromagnetic phenomena to help students achieve a more thorough understanding of the subject. In the 1st edition, superconductivity was emphasized, a focus that continued in the 2nd edition, which strengthened the E-B analogy by comparing equipotential surfaces in electricity to equivector potential surfaces in magnetism. The 3rd edition introduces the concept of mean magnetic flux, which aids in determining inductance from magnetic energy. It also demonstrates how vector potential can be directly used to calculate electromotive force. A unique phenomenon is presented when applying current to a superconducting transmission line, where the induced electric field's vector potential is perpendicular to the current. This deviation from common equations can still be explained through Maxwell&’s theory, leading to the correct solution. For a more in-depth grasp of electricity and magnetism, students are encouraged to use Exercises in Electricity and Magnetism by the same author, which offers 400 practice problems. This textbook is ideal for advanced students of physics, astrophysics, or engineering, as well as a valuable reference for professional scientists.

Electrodynamics of Density Ducts in Magnetized Plasmas: The Mathematical Theory of Excitation and Propagation of Electromagnetic Waves in Plasma Waveguides
by I G Kondratiev A V Kudrin T M ZaboronkovaProviding a systematic and self-contained treatment of excitation, propagation and re- emission of electromagnetic waves guided by density ducts in magnetized plasmas, this book describes in detail the theoretical basis of the electrodynamics of ducts. The classical dielectric-waveguide theory in open guiding systems in magnetoplasma is subjected to rigorous generalization. The authors emphasize the conceptual physical and mathematical aspects of the theory, while demonstrating its applications to problems encountered in actual practice. The opening chapters of the book discuss the underlying physical phenomena, outline some of the results obtained in natural and artificial density ducts, and describe the basic theory crucial to understanding the remainder of the book. The more specialized and complex topics dealt with in subsequent chapters include the theory of guided wave propagation along axially uniform ducts, finding the field excited by the source in the presence of a duct, excitation of guided modes, the asymptotic theory of wave propagation along axially nonuniform ducts, and mode re-emission from a duct. The full wave theory is used throughout most of the book to ensure consistency, and the authors start with simpler cases and gradually increase the complexity of the treatment.

Electromagnetic Form Factors of Charmed Baryons in Lattice QCD (Springer Theses)
by Kadir Utku CanThis thesis presents the first lattice quantum chromodynamics (QCD) approach to the charmed baryon regime, building on the knowledge and experience gained with former lattice QCD applications to nucleon structure. The thesis provides valuable insights into the dynamics of yet unobserved charmed baryon systems. Most notably, it confirms that the expectations of model or effective field theoretical calculations of heavy-hadron systems hold qualitatively, while also demonstrating that they conflict with the quantitative results, pointing to a tension between these complementary approaches. Further, the book presents a cutting-edge approach to understanding the structure and dynamics of hadrons made of quarks and gluons using QCD, and successfully extends the approach to charmed hadrons. In particular, the thesis investigate a peculiar property of charmed hadrons whose dynamics, i.e., structure, deviates from their counterparts, e.g., those of protons and neutrons, by employing the lattice QCD approach —a state-of-the-art numerical method and the powerful ab initio, non-perturbative method.
Electromagnetic Sources and Electromagnetic Fields (Modern Antenna)
by Gaobiao XiaoThis book presents a modified spherical harmonic expansion method in which the electromagnetic fields and their sources are expanded with the same set of spherical vector basis functions in a similar procedure. Explicit expressions for the electromagnetic fields, potentials, energies, and the related Green’s functions are derived for the spherical modes in both frequency domain and time domain. Based on the formulation, the relationships between the electromagnetic sources, the electromagnetic far fields, and the electromagnetic near fields are clearly revealed. In particular, a nonuniform transmission line model is developed for intuitively characterizing the total radiation process. The introduction of the cutoff radius and the cutoff mode degree provides a simple reference for determining the numbers of degrees of freedom of the fields associated with sources in a bounded region. Based on the theory, an efficient hybrid method for synthesizing antenna arrays with complex footprints is proposed and demonstrated with several numerical examples. Effective algorithms are also developed for reconstructing the radiating part of the current sources.This book is intended for researchers, engineers, and graduate students who are interested in studying the energy transfer in electromagnetic radiation, synthesis and measurement of antenna arrays, and applications of inverse electromagnetic source problems.
