Angewandte Statistik mit R für Agrarwissenschaften: Versuchsplanung und -auswertung mit konkreten Beispielen und Übungsaufgaben
by Dieter Rasch Rob VerdoorenDieses Buch führt in die angewandte Statistik für Agrarwissenschaften ein und unterstützt bei der Forschung in der Pflanzen- und Tierproduktion und im Feldversuchswesen. Es nutzt ausgiebig das frei verfügbare Programmpaket R: Über das gesamte Buch hinweg werden im Rahmen umfangreicher Beispiele passende R-Programmcodes angegeben und erläutert. Die Codes können mit eigenen Daten kombiniert und so zur Planung und Auswertung eigener Versuche verwendet werden. So können etwa Wachstumsfunktionen angepasst, Varianzanalysen berechnet oder optimale Versuchspläne und minimale Stichprobenumfänge gefunden werden und vieles mehr. Eine Installationsbeschreibung für R wird ebenfalls zur Verfügung gestellt. Zahlreiche Übungsaufgaben mit Lösungen ergänzen das Buch, so dass es als Lehr- und Nachschlagewerk nutzbar ist. Besonders hervorzuheben ist, dass auch balancierte unvollständige Blockanlagen (BUB) erläutert werden und erstmalig eine vollständige Liste kleinster (mit möglichst geringer Anzahl von Blocks) BUB für bis zu v = 25 Behandlungen und Blockgrößen ≤ v/2 im Netz zur Verfügung gestellt wird. Für Sortenversuche sind die BUB allerdings oft nicht nutzbar, weil sie zu viele Wiederholungen erfordern. Dafür haben sich „verallgemeinerte Gitter“ oder alpha-Anlagen bewährt, die ebenfalls behandelt werden.

Angiogenesis in Adipose Tissue
by Yihai CaoAngiogenesis has recently played a critical role in regulation of adipose tissue expansion and regression. Like most other tissues in the body, adipose expansion and regression is accompanied by alteration of blood vessel density and structures. The vascular alteration plays an active role in regulation of adipose tissue size and functions. Targeting blood vessels in the adipose tissue have demonstrated to be a novel approach for possibly treatment of cancer, obesity and other metabolic diseases. This book provides the most updated information on this type research and discusses future opportunities for therapy..

Angle Resolved Photoemission Spectroscopy of Delafossite Metals (Springer Theses)
by Veronika SunkoThis thesis describes the results of angle resolved photoemission spectroscopy experiments on delafossite oxide metals, and theoretical work explaining these observations. The study was motivated by the extraordinarily high conductivity of the non-magnetic delafossites PdCoO2 and PtCoO2, the measurement of whose electronic structure is reported and discussed. Two unexpected effects were observed in the course of the investigation; each is described and analysed in detail. Firstly, a previously unrecognised type of spectroscopic signal, allowing the non-magnetic probe of photoemission to become sensitive to spin-spin correlations, was observed in the antiferromagnetic PdCrO2. Its origin was identified as the Kondo-like coupling of itinerant and Mott insulating electrons. Furthermore, surface states exhibiting an unusually large Rashba-like spin-splitting were observed on the transition metal terminated surfaces of delafossites. The large inversion symmetry breaking energy scale, a consequence of the unusual structure of the surface layer, is identified as the origin of the effect.
Angle-Resolved Photoemission Spectroscopy Studies of 2D Material Heterostructures (Springer Theses)
by Eryin WangThis book focuses on angle-resolved photoemission spectroscopy studies on novel interfacial phenomena in three typical two-dimensional material heterostructures: graphene/h-BN, twisted bilayer graphene, and topological insulator/high-temperature superconductors. Since the discovery of graphene, two-dimensional materials have proven to be quite a large “family”. As an alternative to searching for other family members with distinct properties, the combination of two-dimensional (2D) materials to construct heterostructures offers a new platform for achieving new quantum phenomena, exploring new physics, and designing new quantum devices. By stacking different 2D materials together and utilizing interfacial periodical potential and order-parameter coupling, the resulting heterostructure’s electronic properties can be tuned to achieve novel properties distinct from those of its constituent materials. This book offers a valuable reference guide for all researchers and students working in the area of condensed matter physics and materials science.
Angle-Resolved Photoemission Spectroscopy Study of Spin Fluctuations in the Cuprate Superconductors (Springer Theses)
by Francisco RestrepoThis thesis makes significant advances towards an understanding of superconductivity in the cuprate family of unconventional, high-temperature superconductors. Even though the high-temperature superconductors were discovered over 35 years ago, there is not yet a general consensus on an acceptable theory of superconductivity in these materials. One of the early proposals suggested that collective magnetic excitations of the conduction electrons could lead them to form pairs, which in turn condense to form the superconducting state at a critical temperature Tc. Quantitative calculations of Tc using experimental data were, however, not available to verify the applicability of this magnetic mechanism. In this thesis, the author constructed an angle-resolved photoemission apparatus that could provide sufficiently accurate data of the electronic excitation spectra of samples in the normal state, data which was furthermore unusually devoid of any surface contamination. The author also applied the Bethe-Salpeter method to his uncommonly pristine and precise normal state data, and was able to predict the approximate superconducting transition temperatures of different samples. This rare combination of experiment with sophisticated theoretical calculations leads to the conclusion that antiferromagnetic correlations are a viable candidate for the pairing interaction in the cuprate superconductors.
Angle-Resolved Photoemission Spectroscopy on High-Temperature Superconductors: Studies of Bi2212 and Single-Layer FeSe Film Grown on SrTiO3 Substrate (Springer Theses)
by Junfeng HeThis book mainly focuses on the study of the high-temperature superconductor Bi2Sr2CaCu2O8+δ (Bi2212) and single-layer FeSe film grown on SrTiO3 (STO) substrate by means of angle-resolved photoemission spectroscopy (ARPES). It provides the first electronic evidence for the origin of the anomalous high-temperature superconductivity in single-layer FeSe grown on SrTiO3 substrate. Two coexisted sharp-mode couplings have been identified in superconducting Bi2212. The first ARPES study on single-layer FeSe/STO films has provided key insights into the electronic origin of superconductivity in this system. A phase diagram and electronic indication of high Tc and insulator to superconductor crossover have been established in the single-layer FeSe/STO films. Readers will find essential information on the techniques used and interesting physical phenomena observed by ARPES.
Angle-Resolved Photoemission Study of Kagome Superconductors AV3Sb5 (Springer Theses)
by Takemi KatoThis book presents high-resolution angle-resolved photoemission spectroscopy (ARPES) experiments on kagome superconductors KV3Sb5, RbV3Sb5, and CsV3Sb5—an ideal material family for studying rich physical phenomena originating from the geometric structure of kagome lattice—with the aim of elucidating the electronic structure and the origin of charge density wave (CDW) and superconductivity. The book begins with an introduction to kagome superconductors, followed by a description of ARPES which is the main tool used in the presented work in this book. The part of the experimental results consists of three chapters: The first chapter describes observation of low-energy excitations, Fermi-surface and momentum-dependent CDW gap by high-resolution ARPES on CsV3Sb5 and KV3Sb5; the second chapter shows evolution of electronic states upon alkali-metal dosing and isovalent substitution, and discusses their relation to modulation of physical properties; the other chapter provides the result of micro-ARPES on KV3Sb5, RbV3Sb5, and CsV3Sb5, and demonstrates the surface-termination- and alkali-metal-dependent three dimensional CDW character.
Anglo-american Connections In Japanese Chemistry
by Yoshiyuki KikuchiAnglo-Japanese and American-Japanese connections in chemistry had a major impact on the institutionalization of scientific and technological higher education in Japan from the late nineteenth century and onwards. They helped define the structure of Japanese scientific pedagogical and research system that lasted well into the post-World World II period of massive technological development, when it became one of the biggest providers of chemists and chemical engineers in the world next to Europe and the United States. In telling this story, Anglo-American Connections in Japanese Chemistry explores various sites of science education such as teaching laboratories and classrooms - where British and American teachers mingled with Japanese students - to shed new light on the lab as a site of global human encounter and intricate social relations that shaped scientific practice.

Anima Mundi: The Rise Of The World Soul Theory In Modern German Philosophy (International Archives of the History of Ideas Archives internationales d'histoire des idées #202)
by Miklós VassányiThis work presents and philosophically analyzes the early modern and modern history of the theory concerning the soul of the world, anima mundi. The initial question of the investigation is why there was a revival of this theory in the time of the early German Romanticism, whereas the concept of the anima mundi had been rejected in the earlier, classical period of European philosophy (early and mature Enlightenment). The presentation and analysis starts from the Leibnizian-Wolffian school, generally hostile to the theory, and covers classical eighteenth-century physico-theology, also reluctant to accept an anima mundi. Next, it discusses early modern and modern Christian philosophical Cabbala (Böhme and Ötinger), an intellectual tradition which to some extent tolerated the idea of a soul of the world. The philosophical relationship between Spinoza and Spinozism on the one hand, and the anima mundi theory on the other is also examined. An analysis of Giordano Bruno's utilization of the concept anima del mondo is the last step before we give an account of how and why German Romanticism, especially Baader and Schelling asserted and applied the theory of the Weltseele. The purpose of the work is to prove that the philosophical insufficiency of a concept of God as an ens extramundanum instigated the Romantics to think an anima mundi that can act as a divine and quasi-infinite intermediary between God and Nature, as a locum tenens of God in physical reality.
Animal Agriculture: Research To Meet Human Needs In The 21st Century
by Wilson G. PondFirst published in 1980. Animal agriculture serves human needs. Three-fourths of the protein, one-third of the energy, most of the calcium and phosphorus and substantial amounts of essential vitamins and other minerals in the American diet are from animal products. Recognizing that innovative research holds the key to meeting these challenges, 210 concerned individuals convened at Boyne Mountain, Michigan, May 4 to 9, 1980. Their goal was to identify priorities for future research to enable animal agriculture to efficiently and effectively serve human needs in the 21st century. These proceedings represent the best collective judgment on research priorities by a group of informed and dedicated people concerned with the future role of animal agriculture in meeting human needs.
