Numerically Solving Polynomial Systems With Bertini

Numerically Solving Polynomial Systems With Bertini

This book is a guide to concepts and practice in numerical algebraic geometry - the solution of systems of polynomial equations by numerical methods. Through numerous examples, the authors show how to apply the well-received and widely used open-source Bertini software package to compute solutions, including a detailed manual on syntax and usage options. The authors also maintain a complementary web page where readers can find supplementary materials and Bertini input files. Numerically Solving Polynomial Systems with Bertini approaches numerical algebraic geometry from a user's point of view with numerous examples of how Bertini is applicable to polynomial systems. It treats the fundamental task of solving a given polynomial system and describes the latest advances in the field, including algorithms for intersecting and projecting algebraic sets, methods for treating singular sets, the nascent field of real numerical algebraic geometry, and applications to large polynomial systems arising from differential equations.Those who wish to solve polynomial systems can start gently by finding isolated solutions to small systems, advance rapidly to using algorithms for finding positive-dimensional solution sets (curves, surfaces, etc.), and learn how to use parallel computers on large problems. These techniques are of interest to engineers and scientists in fields where polynomial equations arise, including robotics, control theory, economics, physics, numerical PDEs, and computational chemistry.

Die auf die 1819 vom Reichsfreiherrn Karl vom Stein gegrundete "Gesellschaft fur altere deutsche Geschichtskunde" zuruckgehenden Monumenta Germaniae Historica haben die Aufgabe, durch kritische Quellen-Ausgaben und -Studien der wissenschaftlichen Erforschung der mittelalterlichen Geschichte Deutschlands und Europas zu dienen. Dieses Ziel verfolgen sie dadurch, dass sie in ihren Editionsreihen mittelalterliche Textquellen der Forschung zuganglich machen und durch kritische Studien zur wissenschaftlichen Erforschung der deutschen und europaischen Geschichte beitragen. Die Aufgaben der Monumenta Germaniae Historica haben sich in den letzten Jahrzehnten durch die Einbeziehung neuer Quellengruppen und durch die Vermehrung der Forschungsbereiche stetig erweitert. Neben Werken der Geschichtsschreibung, Urkunden, Gesetzen und Rechtsbuchern werden auch Briefsammlungen, Dichtungen, Memorialbucher und Necrologe, politische Traktate und Schriften zur Geistesgeschichte herausgegeben.
Solution NMR of Paramagnetic Molecules

Solution NMR of Paramagnetic Molecules

NMR is a growing technique which represents a generalized, spread, common tool for spectroscopy and for structural and dynamic investigation. Part of the field of competence of NMR is represented by molecules with unpaired electrons, which are called paramagnetic. The presence of unpaired electrons is at the same time a drawback (negative effect) and a precious source of information about structure and dynamics. New phenomena and effects are described which are due to the high magnetic fields and advances in the methodology. Solution NMR of Paramagnetic Molecules is unique in dealing with these matters. The scope is that of presenting a complete description, which is both rigorous and pictorial, of theory and experiments of NMR of paramagnetic molecules in solution. Pertinent examples are described. From the time dependent behaviour of electrons in the various metal ions including polimetallic systems to the hyperfine-based information, and from NMR experiments to constraints for solution structure determination. The book's major theme is how to perform high resolution NMR experiments and how to obtain structural and dynamic information on paramagnetic metal ion containing systems.

How companies like Dollar Shave Club and Rent the Runway rewrite the rules of commerce by pursuing outcomes rather than products and services. The seventh book in the Management on the Cutting Edge series—for business professionals looking to do deliver excellent customer service while maximizing value and revenue. Would you rather pay for healthcare or for better health? For school or education? For groceries or nutrition? A car or transportation? A theater performance or entertainment? In The Ends Game, Marco Bertini and Oded Koenigsberg describe how some firms are rewriting the rules of commerce: instead of selling the “means” (their products and services), they adopt innovative revenue models to pursue “ends” (actual outcomes). They examine companies such as: • Dollar Shave Club • Rent the Runway • Netflix • Spotify • Michelin • Adobe • Pearson • And many more! They show that paying by the pill, semester, food item, vehicle, or show does not necessarily reflect the value that customers actually derive from their purchases. Revenue models anchored on the ownership of products, they argue, are patently inferior.
Understanding and Preventing Suicide

Understanding and Preventing Suicide

Every 18 minutes, there is a suicide attempt somewhere in the United States, with some 30,000 of those resulting in completed suicide each year. Worldwide, there are more than 1 million suicides annually. We know the basic facts: Most of the people were depressed or suffered another mental illness, and many were facing stressful life events with which they could not cope. But is there no way to prevent the tragedy? Author Kristine Bertini, a clinical psychologist, says one of the most effective means may be to understand first how suicidal tendencies and thinking develop, how environment, biology, culture, and societal factors all play a role in predisposing some people to give up hope and see death as the only way to end their suffering. In this book, Bertini explains the development of suicidal thinking and, through patient vignettes, illustrates the ways this thinking develops. She also describes and illustrates signals friends and loved ones as well as professionals can watch for pointing to such thinking, which may be kept secretive by the person at risk, as well as approaches that can be used to alter tendencies and thinking for the person at risk.Treatments and programs are explained for coping and recovery by those who consider or attempt suicide, as are approaches to help friends, family, and others affected by completed suicides. This work includes consideration of suicide letters and the insights they have given professionals trying to stop such losses, as well as difficult questions that have been raised about the right to suicide. An appendix lists hotlines, counseling, therapy, and other support services nationwide.
