Spikes and Shocks
by Angelos Gkanoutas-LeventisThis book proposes that price volatility and speculation in the oil market originate from a decades-long process of financialisation. The author challenges mainstream critical accounts of the market that typically invoke the notion of a global oil shortage and so-called 'peak oil' arguments. Instead, he argues that the development of the market has been punctuated by recurring oil price shocks. Chapters examine the evolution of the international oil market and investigate how, and to what effect, the process of financialisation has transformed the structure and dynamics of the global oil market from 1980 to the present day. In doing so, the book suggests that the process of financialisation is both the cause and the proof of a profound change in the structure of the global oil market, that has turned the triangle of producers, consumers, and mediators that characterised the oil market until the 1980s into a four-tier structure through the addition of financial actors.

Spin Dynamics in Two-Dimensional Quantum Materials: A Theoretical Study (Springer Theses)
by Marc Vila TusellThis thesis focuses on the exploration of nontrivial spin dynamics in graphene-based devices and topological materials, using realistic theoretical models and state-of-the-art quantum transport methodologies. The main outcomes of this work are: (i) the analysis of the crossover from diffusive to ballistic spin transport regimes in ultraclean graphene nonlocal devices, and (ii) investigation of spin transport and spin dynamics phenomena (such as the (quantum) spin Hall effect) in novel topological materials, such as monolayer Weyl semimetals WeTe2 and MoTe2. Indeed, the ballistic spin transport results are key for further interpretation of ultraclean spintronic devices, and will enable extracting precise values of spin diffusion lengths in diffusive transport and guide experiments in the (quasi)ballistic regime. Furthermore, the thesis provides an in-depth theoretical interpretation of puzzling huge measured efficiencies of the spin Hall effect in MoTe2, as well as a prediction of a novel canted quantum spin Hall effect in WTe2 with spins pointing in the yz plane.
Spin Ice (Springer Series in Solid-State Sciences #197)
by Masafumi Udagawa Ludovic JaubertThis book deals with a new class of magnetic materials, spin ice. Spin ice has become the canonical example of modern frustrated magnetism where competing interactions between spins set the rules for an emergent magnetostatic gauge field theory. Excitations take the form of magnetic monopoles or can condense via a Higgs mechanism. Beyond classical spin ice, the book describes the new physics emerging when quantum coherence (spin liquids, photon-like excitations) and itinerant electrons (anomalous Hall effect) are included in artificial systems. This first book dedicated to spin ice is a review of the current understanding of the field, both on the theoretical and experimental levels, written by leading experts. The book is written in a linear way with very few prerequisites. It also contains textbook-like descriptions of theoretical methods to help advanced students and researchers to enter the field.
Spin Physics in Semiconductors
by Mikhail I. DyakonovThe purpose of this collective book is to present a non-exhaustive survey of sp- related phenomena in semiconductors with a focus on recent research. In some sense it may be regarded as an updated version of theOpticalOrientation book, which was entirely devoted to spin physics in bulk semiconductors. During the 24 years that have elapsed, we have witnessed, on the one hand, an extraordinary development in the wonderful semiconductor physics in two dim- sions with the accompanying revolutionary applications. On the other hand, during the last maybe 15 years there was a strong revival in the interest in spin phen- ena, in particular in low-dimensional semiconductor structures. While in the 1970s and 1980s the entire world population of researchers in the ?eld never exceeded 20 persons, now it can be counted by the hundreds and the number of publications by the thousands. This explosive growth is stimulated, to a large extent, by the hopes that the electron and/or nuclear spins in a semiconductor will help to accomplish the dream of factorizing large numbers by quantum computing and eventually to develop a new spin-based electronics, or "spintronics". Whether any of this will happen or not, still remains to be seen. Anyway, these ideas have resulted in a large body of interesting and exciting research, which is a good thing by itself. The ?eld of spin physics in semiconductors is extremely rich and interesting with many spectacular effects in optics and transport.

Spin-Polarized Two-Electron Spectroscopy of Surfaces (Springer Series in Surface Sciences #67)
by Sergey Samarin Oleg Artamonov Jim WilliamsThis book presents developments of techniques for detection and analysis of two electrons resulting from the interaction of a single incident electron with a solid surface. Spin dependence in scattering of spin-polarized electrons from magnetic and non-magnetic surfaces is governed by exchange and spin-orbit effects. The effects of spin and angular electron momentum are shown through symmetry of experimental geometries: (i) normal and off normal electron incidence on a crystal surface, (ii) spin polarization directions within mirror planes of the surface, and (iii) rotation and interchange of detectors with respect to the surface normal. Symmetry considerations establish relationships between the spin asymmetry of two-electron distributions and the spin asymmetry of Spectral Density Function of the sample, hence providing information on the spin-dependent sample electronic structure. Detailed energy and angular distributions of electron pairs carry information on the electron-electron interaction and electron correlation inside the solid. The “exchange – correlation hole” associated with Coulomb and exchange electron correlation in solids can be visualized using spin-polarized two-electron spectroscopy. Also spin entanglement of electron pairs can be probed. A description of correlated electron pairs generation from surfaces using other types of incident particles, such as photons, ions, positrons is also presented.
Spin-While-Burn: The New Approach for Tiny Medical Device Fabrication (SpringerBriefs in Applied Sciences and Technology)
by Saiful Bahri Mohamed Mohd Shahir Kasim Muhammad Akmal ZakariaThis book explains the challenges and advancements in cutting precise cylindrical shapes on difficult materials through spark erosion. Titled "Spin while Burn," it addresses the drawbacks associated with this process, including unsatisfactory surface finish and limited productivity. Despite utilizing advanced computing and statistical optimization methods, achieving the ideal balance between material removal rate (MRR) and surface quality remains elusive. In response, the book introduces a hybrid ultrasonic-assisted approach in the wire electrical discharge turning (WEDT) process. By integrating a rotating workpiece with ultrasonic vibration, the authors evaluate its impact on MRR and surface finish. Through meticulous design experiments and statistical analysis, they explore various cutting parameters and machining paths. The book highlights the characterization of machined surfaces through elemental analysis and surface morphology evaluations. The results demonstrate the positiveeffects of integrating ultrasonic vibration into WEDT, even without optimized ultrasonic parameters. By reducing electrode wire debris and employing multi-objective parameter optimization using the genetic algorithm, significant improvements are achieved in MRR and surface roughness compared to conventional WEDT. "Spin while Burn" consists of five chapters, delving into the challenges, history, principles, performance, and future perspectives of the Spin-while-Burn process in manufacturing. This comprehensive book offers valuable insights into enhancing surface quality and productivity in the cutting of precise cylindrical shapes on challenging materials through spark erosion.
Spinal Cord Injury: Progress, Promise, and Priorities
by Institute of Medicine of the National AcademiesAn estimated 11,000 spinal cord injuries occur each year in the United States and more than 200,000 Americans suffer from maladies associated with spinal cord injury. This includes paralysis, bowel and bladder dysfunction, sexual dysfunction, respiratory impairment, temperature regulation problems, and chronic pain. During the last two decades, longstanding beliefs about the inability of the adult central nervous system to heal itself have been eroded by the flood of new information from research in the neurosciences and related fields. However, there are still no cures and the challenge of restoring function in the wake of spinal cord injuries remains extremely complex. Spinal Cord Injury examines the future directions for research with the goal to accelerate the development of cures for spinal cord injuries. While many of the recommendations are framed within the context of the specific needs articulated by the New York Spinal Cord Injury Research Board, the Institute of Medicine's panel of experts looked very broadly at research priorities relating to future directions for the field in general and make recommendations to strengthen and coordinate the existing infrastructure. Funders at federal and state agencies, academic organizations, pharmaceutical and device companies, and non-profit organizations will all find this book to be an essential resource as they examine their opportunities.

Spinning the Cosmos: Volvelles in the Early Modern Commentary Tradition of Johannes de Sacrobosco’s De Sphaera (SpringerBriefs in History of Science and Technology)
by Alica-Nana CitronThis open access book investigates the epistemological concept of and the knowledge transfer interwoven with the moveable paper wheels found in medieval and early modern books—the so-called &“volvelles.&” The earliest known volvelles emerged in the mid-thirteenth century and were cut out and installed by the reader, often appearing in books dealing with astronomical subjects. The brain processes and remembers images more easily than words—the so-called &“picture superiority effect&”—especially if the images move, making volvelles a useful method to help students of the Quadrivium memorizing the heavenly movements, thus the composition of a device embedded within a text promises a comprehensive insight into the didactic concepts of early modern knowledge transfer. The Tractatus de Sphaera by Johannes de Sacrobosco (1195–1256), the standard university textbook for astronomy from the thirteenth until the seventeenth century, was particularly noted as containing volvelles of different kinds. The project &“The Sphere,&” located at the Max Planck Institute for the History of Science in Berlin, has collected a corpus of 359 printed De sphaera editions, building a promising basis for examining different volvelles and placing the results in a cultural context. These volumes had never been analyzed in detail before, nor was there such a large corpus that could provide a quantitative database for such an investigation. The results of the book show that a book and knowledge tradition as widespread as that of the Sphaera contained more than one third of volvelles and was used in university teaching in the early modern period. For historians, this sheds light on a new aspect of movable paper instruments in university didactics and book history in the early modern period.
