This book provides an overview of multiple aspects of spatial language understanding and explores recent trends of modeling based on very large foundational models and their applications. The authors address the following five main themes: spatial semantic representations in both symbolic and sub-symbolic spaces; spatial information extraction computational models; reasoning over spatial language; commonsense spatial understanding; and multiple modern and state-of-the-art downstream applications of spatial language understanding including dialogue systems, narrative discourse, and grounding language in the physical world with the multi-modal problem settings. One of the essential functions of natural language is to express spatial relationships between objects. Linguistic constructs can encode highly complex structures of objects, spatial relations between them, and patterns of motion through space relative to a reference point. The complexity of spatial language understanding and its

Rarely in the history of international tax law have there been so many evolutions in such a short space of time: In a dizzying array of reports, work programmes, consultations and announcements, the OECD, with the active support of the EU, has created a framework for a global minimum tax (Pillar Two or GloBE). In the meanwhile, jurisdictions are faced with the practical difficulties of incorporating an incredibly complex set of rules into their domestic legal systems. This book aims to shed light on the fundamental and technical issues surrounding the global minimum tax. It seeks to unravel the complex ramifications of GloBE's technical framework and aims to explore the relationship between the OECD's soft law materials, including the OECD's GloBE Model Rules and the GloBE Commentary, tax treaties and the EU's recently adopted GloBE-Directive.The author not only analyses Pillar Two from a technical and a policy perspective but also provides for a comprehensive examination of the compat

A BRILLIANT BLEND OF MILITARY SCIENCE FICTION AND ARTHUR C. CLARKE-LEVEL SPECULATIVE WONDER BY A WORKING SPACE SCIENTIST!NO TIME LIKE THE PRESENTHumanity has finally made it to the stars. Colony worlds thrive and there is general peace among the settled systems. Until now.Matte black ships of an advanced design appear in colonial systems. Their drives and weapons are not extremely advanced beyond their Terran counterparts―just superior enough to be utterly devastating. Colonies and their populations are obliterated. Once-settled worlds are rendered radioactive wastelands. Earth herself lies defenseless before the marauding enemy.DEFEND THE SKIES OF EARTHStanding against the invasion are two of humanity’s finest starship captains: Winslow Price of the British Space Navy and Anika Ahuja of the Indian Space Forces. Compatriots. Fierce competitors. Former lovers. Now they are on a quest that will plumb the scientific wells of existence, where the primordial knot of spacetime may be unrave

Predominant climate change narratives emphasize a global emissions problem, while diagnoses of environmental crises have long focused a modern loss of meaning, value, and enchantment in nature. Yet neither of these common portrayals of environmental emergency adequately account for the ways climate change is rooted in extractivisms that have been profoundly enchanted.The proposed critical petro-theology analyzes the current energy driven climate crisis through critical gender, race, decolonial, and postsecular lenses. Both predominant narratives obscure the entanglements of bodies and energy: how energy concepts and practices have consistently delineated genres of humanity and how energy systems and technologies have shaped bodies. Consequently, these analytical and ethical aims inform an exploration of alternative embodied energies that can be attended to in the disrupted time/space of energy intensive, extractive capitalism.

The range of phenomena that manifest at all different time and length scales and the wide range of sizes of space objects, from minor bodies in the Solar System to exoplanets, and from dust particles to Jupiter-size bodies, require the development of dynamical modeling and analysis tools that can handle these different scales. This volume collects contributions given by distinguished scientists at the hybrid IAU Symposium 364. The methods in dynamics modeling of space objects have already reached a state of maturity, and their implementation provided a large number of important results pertaining to both the theory and their applications. The contributions cover the recent advances in the multi-scale dynamics of natural and artificial space objects from various perspectives, which will benefit graduate students and researchers working in the fields of celestial mechanics, astrodynamics, planetary sciences, applied mathematics and dynamical systems.

Dr. Roget's system brings together in one place all the terms associated with a single thought or concept; it allows a wide-ranging survey of language within a book of relatively modest size, without the space-consumi

Higher-order networks describe the many-body interactions of a large variety of complex systems, ranging from the the brain to collaboration networks. Simplicial complexes are generalized network structures which allow us to capture the combinatorial properties, the topology and the geometry of higher-order networks. Having been used extensively in quantum gravity to describe discrete or discretized space-time, simplicial complexes have only recently started becoming the representation of choice for capturing the underlying network topology and geometry of complex systems. This Element provides an in-depth introduction to the very hot topic of network theory, covering a wide range of subjects ranging from emergent hyperbolic geometry and topological data analysis to higher-order dynamics. This Elements aims to demonstrate that simplicial complexes provide a very general mathematical framework to reveal how higher-order dynamics depends on simplicial network topology and geometry.

The law of treaties is in constant motion, understood not only as locomotion, but also as motion through time and as change. Thus, kinesis and stasis, two sides of the same concept of 'motion', are the central themes of Treaties in Motion. The concept of motion adopted in this book is based on the philosophy of Aristotle. He identified six types of motion: creation (genesis), increase (auxesis), diminution (meiosis), alteration (alloiosis), destruction (phthora), and change of place (kata topon metabole), which has been amended by the authors to change in space-time (kata topon kai chronon metavole) to reflect our modern scientific understanding of time as a dimension through which motion and change occurs. Each chapter's analysis proceeds by focusing on a specific area of a treaty's 'life-cycle', where each type of motion shines through and is described through three different frames of reference: treaties, the Vienna Convention of the Law of Treaties, and customary law.

This book combines a comprehensive state-of-the-art analysis of bifurcations of discrete-time dynamical systems with concrete instruction on implementations (and example applications) in the free MATLAB® software MatContM developed by the authors. While self-contained and suitable for independent study, the book is also written with users in mind and is an invaluable reference for practitioners. Part I focuses on theory, providing a systematic presentation of bifurcations of fixed points and cycles of finite-dimensional maps, up to and including cases with two control parameters. Several complementary methods, including Lyapunov exponents, invariant manifolds and homoclinic structures, and parts of chaos theory, are presented. Part II introduces MatContM through step-by-step tutorials on how to use the general numerical methods described in Part I for simple dynamical models defined by one- and two-dimensional maps. Further examples in Part III show how MatContM can be used to analyze

Gravitational waves were predicted 100 years ago by Einstein as part of his general theory of relativity. This volume contains the exciting results presented at IAU Symposium 338, following the announcement of the first results of the observation of the collision of neutron stars by the LIGO and Virgo Advanced detectors, and follow-up observations by many ground-based and space telescopes. These observations provided an incredible context for the talks, posters and discussions at the meeting, fostering new interactions and collaborations between physicists and astronomers in an exciting new era of multimessenger astrophysics. For the first time, space-time messengers (gravitational waves) and electromagnetic ones (visible, infrared and ultraviolet light, x-rays, gamma-rays, radio waves) can be correlated, to increase our understanding of binary systems of compact objects, rotating or exploding stars and other astrophysical phenomena. A new window has opened through which we can view th

This pioneering, course-tested text is the first to combine communications theory with the physics of optical communications. Comprehensive and rigorous, it brings together an in-depth treatment of the physical characteristics of the guided lightwave channel with the study of modern methods of algorithmic-based communication in time and space. The many different levels at which a lightwave communication signal can be described are integrated to provide a unified explanation of how a commonplace bit stream is transformed into a physical lightwave, how that lightwave travels through an optical fiber, and how it is then transformed back into the bit stream. Background fundamentals such as linear systems and electromagnetics are explained in relation to modern topics such as channel models, encoding, modulation and interference, and end-of-chapter problems are provided throughout. This is an essential text for students taking courses on optical communications, as well as researchers and pr

The Sun is an active and variable star. Instabilities and non-stationary processes connected to the solar magnetic field and its evolutionary mechanisms modify its radiative and particle output on different time scales, from seconds to the evolutionary scale of the star. The Sun's activity affects interplanetary space and planetary environments, through space weather due to short-term activity and space climate on longer timescales. Space weather processes and forecasts are therefore important for both Earth and space within the heliosphere. The multi-disciplinary IAU Symposium 335 on 'Space Weather of the Heliosphere: Processes and Forecasts' gave a balanced overview of the general advances in space weather. It linked various aspects of research in solar, heliospheric and planetary physics, emphasizing cross-disciplinary developments. These companion proceedings, covering interdisciplinary topics and attracting a wide variety of contributors, serves as a timely reference to the intern

Hydroclimatology provides a systematic structure for analysing how the climate system causes time and space variations (both global and local) in the hydrologic cycle. Changes in the relationship between the climate system and the hydrologic cycle underlie floods, drought and possible future influences of global warming on water resources. Land-based data, satellite data, and computer models contribute to our understanding of the complex time and space variations of physical processes shared by the climate system and the hydrologic cycle. Blending key information from the fields of climatology and hydrology - which are not often found in a single volume - this is an ideal textbook for students in atmospheric science, hydrology, Earth and environmental science, geography, and environmental engineering. It is also a useful reference for academic researchers in these fields.
