Cusp

In 2031, a solar flare of incalculable power shifts the Sun’s position as two immense walls erupt out of the earth, encircling it along the equator and from pole to pole. The climatic and geographical chaos that follows pushes civilization to the brink of destruction, and brings about a new world order. Twenty years later, as a fractured humanity struggles to solve the mystery of the Rings that straddle Earth, an enigmatic entity is pushing its own plan for human evolution, using the supercomputer known as CUSP—the first computer designed to run on the software of the human mind. “Metzger takes cutting-edge science, roils it with startling action, and grabs you on a rocket-propelled ride. Cusp is hard science fiction at its best.”—David Brin “Audacious.”—Science Fiction Weekly “Minds will boggle at the extravagance of Metzger’s imagination.”—Kirkus Reviews

These proceedings are based upon introductory talks, research reports and discussions from the NATO Advanced Workshop on the "Morphology and Dynamics of the Polar Cusp", held at Lillehammer, Norway, 7-12 May, 1984. The upper atmosphere at high latitudes is called the "Earth's win dow to outer space". Through various electrodynamic coupling process es as well as through direct transfer of particles many geophysical effects displayed there are direct manifestations of phenomena occurring in the deep space. The high latitude ionosphere will also exert a feedback on the regions of the magnetosphere and atmosphere to which it is coupled, acting as a momentum and energy source and sink, and a source of particles. Of particular interest are the sections of the near space known as the Polar Cusp. A vast portion of the earth's magnetic field envelope is electrically connected to these regions. This geometry results in a spatial mapping of the magnetospheric pro cesses and a focusing on to the ionosphere. In the Polar Cusps the solar wind plasma has also direct access to the upper atmosphere. The polar regions are thus of extreme importance when it comes to under standing the physical processes in the near space and their effect on our environment. The Introductory Talks given at this workshop provided a common background for discussing and understanding the physics of the Polar Cusp. By this book we will make the information which thus was provid ed to the participants of the workshop accessible to a wider audience.

This collection of papers will address the question "What is the Magnetospheric Cusp?" and what is its role in the coupling of the solar wind to the magnetosphere as well as its role in the processes of particle transport and energization within the magnetosphere. The cusps have traditionally been described as narrow funnel-shaped regions that provide a focus of the Chapman-Ferraro currents that flow on the magnetopause, a boundary between the cavity dominated by the geomagnetic field (i.e., the magnetosphere) and the external region of the interplanetary medium. Measurements from a number of recent satellite programs have shown that the cusp is not confined to a narrow region near local noon but appears to encompass a large portion of the dayside high-latitude magnetosphere and it appears that the cusp is a major source region for the production of energetic charged particles for the magnetosphere. Audience: This book will be of interest to space science research organizations in governments and industries, the community of Space Physics scientists and university departments of physics, astronomy, space physics, and geophysics.

Is your birthday between two different signs? Discover new insights into yourself and others with this first-ever guide to cusp astrology. We've all heard the term "born on the cusp"—but what does it mean, exactly? What if you were born just as the sun moves into Aries, but you feel more like a Pisces? If your birthday falls on a date when a sign changes over to another, you probably possess traits of each. Engaging and easy to use, this book goes beyond simple, cut-and-dried archetypes of sun sign astrology, yet doesn't require any special knowledge. You'll get a deeper understanding of your personality and motivations—and those of your partner, friends, family members, and anyone else whose birthday is on the edge of two signs. Organized by date of birth, this astrology book lets you quickly look up your birthday so you can identify your particular strengths, gifts, and challenges. You'll also find out about your career and upcoming opportunities, times of the year when you can expect obstacles and rewards, and which signs are your best matches for love and romance. Helping to illuminate each cusp birthday's characteristics are examples of well-known figures such as Robert Redford and Meryl Streep.

“The ways in which we can redress the past are many and varied,” writes Jean Barman, “and it is up to each of us to act as best we can.” The seventeen essays collected here, originally published between 1996 and 2013, make a valuable contribution toward this laudable goal. With a wide range of source material, from archival and documentary sources to oral histories, Barman pieces together stories of individuals and groups disadvantaged in white settler society because of their gender, race and/or social class. Working to recognize past actors that have been underrepresented in mainstream histories, Barman’s focus is BC on “the cusp of contact.” The essays in this collection include fascinating, though largely forgotten, life stories of the frontier—that space between contact and settlement, where, for a brief moment, anything seemed possible. This volume, featuring over thirty archival photographs and illustrations, makes these important and very readable essays accessible to a broader audience for the first time.

The manifolds investigated in this monograph are generalizations of (XX)-rank one locally symmetric spaces. In the first part of the book the author develops spectral theory for the differential Laplacian operator associated to the so-called generalized Dirac operators on manifolds with cusps of rank one. This includes the case of spinor Laplacians on (XX)-rank one locally symmetric spaces. The time-dependent approach to scattering theory is taken to derive the main results about the spectral resolution of these operators. The second part of the book deals with the derivation of an index formula for generalized Dirac operators on manifolds with cusps of rank one. This index formula is used to prove a conjecture of Hirzebruch concerning the relation of signature defects of cusps of Hilbert modular varieties and special values of L-series. This book is intended for readers working in the field of automorphic forms and analysis on non-compact Riemannian manifolds, and assumes a knowledge of PDE, scattering theory and harmonic analysis on semisimple Lie groups.

Manifolds with fibered cusps are a class of complete non-compact Riemannian manifolds including many examples of locally symmetric spaces of rank one. We study the spectrum of the Hodge Laplacian with coefficients in a flat bundle on a closed manifold undergoing degeneration to a manifold with fibered cusps. We obtain precise asymptotics for the resolvent, the heat kernel, and the determinant of the Laplacian. Using these asymptotics we obtain a topological description of the analytic torsion on a manifold with fibered cusps in terms of the R-torsion of the underlying manifold with boundary.
