La historia de los 1800 kilómetros que la joven autora anduvo en su recorrido a pie por la cordillera del…
Pacífico de los Estados Unidos. Con veintidós años creía que lo había perdido todo en la vida. Tras la muerte de su madre y tomar la decisión de separarse, sus hermanos se dispersaron y ella se quedó sin pilares sobre los que construir su vida. Cuatro años después de la muerte de su madre toma la decisión más impulsiva de su vida: recorrer el camino del las Cumbres del Pacífico, una ruta de senderismo que recorre toda la costa oeste de los Estados Unidos, desde el desierto Mojave en California y Oregon al estado de Washington. Y decide hacerlo completamente sola. Sin ninguna experiencia en senderismo, y ni tan solo habiendo pasado jamás una noche al aire libre, para ella se trataba de una idea, vaga y extravagante y prometedora.Pero esa promesa se convirtió en la necesidad de volver a juntar las piezas del rompecabezas en que se ha convertido su vida. Narrada con suspense, estilo, sentido del humor y ternura, Savaje consigue atrapar el miedo y los placeres en la vida de una joven que se encuentra en el proceso de forjar su vida contra toda expectativa, en el viaje que la volvió loca, que la fortaleció y que acabó por sanarla. La crítica ha dicho...«Espectacular...Te atrapa... Una aventura que te quita el aliento y una profunda reflexión sobre la naturaleza del dolor y la supervivencia. Un triunfo a nivel literario y personal.»New York Times Book Review «Un libro ameno y a ratos duro, que hará las delicias de senderistas y amantes de la buena literatura con las peripecias de una joven en procesode reconstrucción, a lo largo del viaje que la volvió loca, que la fortaleció y que terminó por sanarla.»EvadiumBy Michael Wood. 2023
A beautifully illustrated travelogue, chronicling the life and work of one of the world greatest poets. Du Fu (712-70) is…
one of China&’s greatest poets. His career coincided with periods of famine, war and huge upheaval, yet his secular philosophical vision, combined with his empathy for the common folk of his nation, ensured that he soon became revered. Like Shakespeare or Dante, his poetry resonates in a timeless manner that ensures it is always relevant and offers something new to the modern generation. Now, in this beautifully illustrated book, broadcaster and historian Michael Wood follows in his footsteps to try to understand the places that inspired Du Fu to write some of the most famous and best-loved poetry the world has known. The themes he wrote about – friendship, family, human suffering – are universal and in our troubled times are just as relevant as they were almost 1,300 years ago.By Niklas Litzenberger. 2023
Teaching is characterized by complex interactions. Therefore, it is difficult to make global statements about a teaching sequence. However, methods…
that aim at a global assessment of teaching have often been used in indicator-based lesson observation. It remains unclear how reliable global assessments of entire lesson sequences are since no statements can be made about dynamic processes taking place. One approach is the State Space Grids (SSG) developed by Hollenstein (2013). These make it possible to relate the development of two teaching characteristics to each other over time to visualize dynamic processes. However, there is no suitable way to numerically capture the relationship between indicators, e.g. to compare such moment-to-moment assessments with global assessments. The aim of this work is therefore to extend the SSG approach to Advanced State Space Grids with mathematically based parameters, to test their practicability, to compare them with global assessments of entire teaching sequences, and to investigate their applicability to physics teaching. Numerical and graphical elements are added to the SSG plot. These include new relation types between the recorded indicators, chi-square tests, and parameters for densities and deviations.This book introduces characterizations of hyperordered structures using latest quantum beam technologies, the advanced theoretical methods for understanding the roles of the…
structures, and the state-of-the-arts materials containing the structures. In this book, the authors focus on the importance of defect complexes to improve functionality of crystals and that of orders of network structures to improve functionality of glass materials. These features can be regarded as interphases between perfect crystals and perfect amorphous, and they are the key factor for the evolution of materials science to a new dimension. The authors call such interphases "hyperordered structures" in this book. This is the first book that comprehensively summarizes glass science, defect science, and quantum beam science. It is valuable not only for active researchers in industry and academia but also graduate students.By Andreas Wipf. 2023

to science students and specialists. Using a minimum of mathematics, a number of qualitative and quantitative examples, and clear illustrations, the author explains the science of thermodynamics in its full historical context, focusing on the concepts of energy and its availability and transformation in thermodynamic processes. His ultimate aim is to gain a deep understanding of the second law—the increase of entropy—and its rather disheartening message of a universe descending inexorably into chaos and disorder. It also examines the connection between the second law and why things go wrong in our daily lives. Readers will enhance their science literacy and feel more at home on the science side of author C. P. Snow's celebrated two-culture, science-humanities divide, and hopefully will feel more at home in the universe knowing that the disorder we deal with in our daily lives is not anyone's fault but Nature's.By Xiujie Deng. 2024

steady-state microbunching (SSMB) which promises high-power, high-repetition rate, narrow-band coherent radiation in an electron storage ring. The contribution of this dissertation consists of three parts: first, answers the question of how to realize SSMB from a beam dynamics perspective; second, reveals what radiation characteristics can we obtain from the formed SSMB; and third, experimentally demonstrates the working mechanism of SSMB in a real machine for the first time. The highlights of this book can be summarized as: Presents the first proof-of-principle experiment of a promising accelerator light source mechanism; Covers precision longitudinal and transverse-longitudinal coupling dynamics in a storage ring; Provides useful formulas and example parameters for high-power infrared, EUV and soft X-ray light source design.By Resa Willis. 2004
Olivia Langdon Clemens was not only the love of Mark Twain's life and the mother of his children, she was…
also his editor, muse, critic and trusted advisor. She read his letters and speeches. He relied on her judgment on his writing, and readily admitted that she not only edited his work, but also edited his public persona.Until now, little has been known about Livy's crucial place in Twain's life. In Resa Willis's affecting and fascinating biography, we meet a dignified, optimistic women who married young, raised three sons and a daughter, endured myriad health problems and money woes and who faithfully traipsed all over the world with Twain--Africa, Europe, Asia--while battling his moodiness and her frailty.Twain adored her. A hard-drinking dreamer with an insatiable wanderlust, he needed someone to tame him. It was Livy who encouraged him to finish his autobiography even through the last stages of her illness. When she died in 1904, Twain's zest for life and writing was gone. He died six years later.A triumph of the biographer's art, Mark and Livy presents the fullest picture yet of one of the most influential women in American letters.By The Association Education. 2023

The renowned Turkish author’s memoir of serving Sultan Mehmed V provides a rare look inside the palace politics of the…
late Ottoman Empire.Before he became one of Turkey’s most famous novelists, Halid Ziya Usakligil served as First Secretary to Sultan Mehmed V. His memoir of that time, between 1909 and 1912, provides first-hand insight into the personalities, intrigues, and inner workings of the Ottoman palace in its final decades.In post-Revolution Turkey, the palace no longer exercised political power. Instead, it negotiated the minefields between political factions, sought ways to unite the empire in the face of nationalist aspirations, and faced the opening salvos of the wars that would eventually overwhelm the country. Usakligil includes interviews with the Imperial family as well as descriptions of royal nuptials, the palaces and its visitors, and the crises that shook the court. He also delivers an insightful and moving portrait of Mehmed V, the man who reigned over the Ottoman Empire through both Balkan Wars and World War I.By Tatiana Chaplina. 2023
This book includes new results of theoretical and experimental studies of various scales of the processes occurring on the earth…
including the lithosphere, atmosphere, and hydrosphere. Intensive development of research in these areas is due to several factors: 1) the widespread introduction of computer technology, allowing the calculation of complex phenomena; 2) the invention and improvement of a new generation of geophysical instruments such as remote observation systems based on ships, aircraft, and satellites, providing a large amount of data to objectively reflect a broad picture of the processes; and 3) the development of measurement techniques, creating opportunities for controllable and reproducible laboratory data acquisition for generation of new ideas and concepts. Their recent developments have facilitated our research and understanding of these academic fields. The book enriches the understanding of the geophysical processes taking place in various environments (lithosphere, hydrosphere, and atmosphere), including the anthropogenic one, and it further contributes to their development. This book is a valuable resource for specialists working in the oil, gas, and engineering industry to improve their understandings of the field.By Ramadan M. Kuridan. 2023

of the neutron transport processes in nuclear reactors and emphasize the numerical computing methods that lead to the prediction of neutron behavior. Detailed derivations and thorough discussions are the prominent features of this book unlike the brevity and conciseness which are the characteristic of most available textbooks on the subject where students find them difficult to follow. This conclusion has been reached from the experience gained through decades of teaching. The topics covered in this book are suitable for senior undergraduate and graduate students in the fields of nuclear engineering and physics. Other engineering and science students may find the construction and methodology of tackling problems as presented in this book appealing from which they can benefit in solving other problems numerically. The book provides access to a one dimensional, two energy group neutron diffusion program including a user manual, examples, and test problems for student practice. An option of a Matlab user interface is also available.By Pedro Bargueño, Ernesto Contreras. 2023
This book offers a primer on the fundamentals and applications of the Geroch-Held-Penrose (GHP) calculus, a powerful formalism designed for…
spacetimes that occur frequently in the teaching of General Relativity. Specifically, the book shows in detail the power of the calculus when dealing with spherically symmetric spacetimes. After introducing the basics, a new look at all the classical spherically symmetric black hole solutions is given within the GHP formalism. This is then employed to give new insights into the Tolman-Oppenheimer-Volkoff equations for stellar structure, including a derivation of new exact anisotropic fluid solutions. Finally, a re-writing of some essential features of black hole thermodynamics within the GHP formalism is performed. The book is based on the authors' lecture notes, used in their undergraduate and graduate lectures and while supervising their upper undergraduate and graduate students. To fully benefit from this concise primer, readers only need an undergraduate background in general relativity.By Stefania Loredana Nita, Marius Iulian Mihailescu. 2023
This book presents the current state of the literature on the fields of homomorphic and searchable encryption, from both theoretical…
and practical points of view. Homomorphic and searchable encryption are still relatively novel and rapidly evolving areas and face practical constraints in the contexts of large-scale cloud computing and big data.Both encryption methods can be quantum-resistant if they use the right mathematical techniques. In fact, many fully homomorphic encryption schemes already use quantum-resistant techniques, such as lattices or characteristics of polynomials – which is what motivated the authors to present them in detail.On the one hand, the book highlights the characteristics of each type of encryption, including methods, security elements, security requirements, and the main types of attacks that can occur. On the other, it includes practical cases and addresses aspects like performance, limitations, etc. As cloud computing and big data already represent the future in terms of storing, managing, analyzing, and processing data, these processes need to be made as secure as possible, and homomorphic and searchable encryption hold huge potential to secure both the data involved and the processes through which it passes.This book is intended for graduates, professionals and researchers alike. Homomorphic and searchable encryption involve advanced mathematical techniques; accordingly, readers should have a basic background in number theory, abstract algebra, lattice theory, and polynomial algebra.
