Zinc Finger Proteins: From Atomic Contact to Cellular Function
The scientists discovered a novel domain associated with zinc, and named this domain "zinc finger. " The number of proteins with similar zinc fingers grew quickly and these proteins are now called C2H2, Cys2His2 or classical zinc finger proteins. To date, about 24,000 C2H2 zinc finger proteins have been recognized. Approximately 700 human genes, or more than 2% of the genome, have been estimated to encode C2H2 finger proteins. From the beginning these proteins were thought to be numerous, but no one could have predicted such a huge number. Perhaps thousands of scientists are now working on C2H2 zinc finger proteins fi-om variou s viewpoints. This field is a good example of how a new science begins with the insight of a few scientists and how it develops by efforts of numerous independent scientists, in contrast to a policy-driven scientific project, such as the Human Genome Project, with goals clearly set at its inception and with work performed by a huge collaboration throughout the world. As more zinc finger proteins were discovered, several subfamilies, such as C2C2, CCHC, CCCH, LIM, RING, TAZ, and FYVE emerged, increasing our understanding of zinc fingers. The knowledge was overwhelming. Moreover, scientists began defining the term "zinc finger" differently and using various names for identical zinc fingers.

Venous Thromboembolism : Prevention and Treatment
Pulmonary thromboembolism in Japan is currently associated with a high mortality rate and remains a concern for patients and medical staff alike. Moreover, as the mechanisms of the condition have been elucidated, it has become clear that much work needs to be done in the field to achieve acceptable results in this country. Thus, Japan has regularly played host to the International Symposium on Pulmonary Thromboembolism . At the most recent symposium, in Sendai, the epidemiology and the treatment of pulmonary thromboembolism, traveler's thrombosis, and the prevention of deep vein thromboembolism were discussed, particularly with reference to the differences between Japan and Western countries. The fruits of the collaboration between that assembly of international specialists can be found in this collection of work. It provides an in-depth look at the current concepts that guide the treatment and prevention of the disease, and at the problem areas that must be improved upon.
Value Creation in Successful LBOs
Daniel Pindur analyzes value creation in successful LBOs on investment level conceptually and empirically from an LBO equity investor perspective. Based on the LBO transaction model, the author decomposes total proceeds to LBO equity investors and derives a two-tier framework of an internal and an external perspective, thereby structuring the conceptual discussion of various determinants affecting these components. Founded on a novel database with detailed company- and transaction-specific information for a sample of 42 realized European LBO investments, he then quantifies LBO investment performance measures and their components and identifies the determinants of value creation in LBO investments.

Two Algebraic Byways from Differential Equations : Gröbner Bases and Quivers
Presents a fascinating collection of lecture notes focusing on differential equations from two viewpoints: formal calculus (through the theory of Gröbner bases) and geometry (via quiver theory). Gröbner bases serve as effective models for computation in algebras of various types.Divided into two parts, the book first discusses the theory of Gröbner bases in their commutative and noncommutative contexts, with a focus on algorithmic aspects and applications of Gröbner bases to analysis on systems of partial differential equations, effective analysis on rings of differential operators, and homological algebra. It then introduces representations of quivers, quiver varieties and their applications to the moduli spaces of meromorphic connections on the complex projective line.
Transitions in Mathematics Education
This book examines the kinds of transitions that have been studied in mathematics education research. It defines transition as a process of change, and describes learning in an educational context as a transition process. The book focuses on research in the area of mathematics education, and starts out with a literature review, describing the epistemological, cognitive, institutional and sociocultural perspectives on transition. It then looks at the research questions posed in the studies and their link with transition, and examines the theoretical approaches and methods used. It explores whether the research conducted has led to the identification of continuous processes, successive steps, or discontinuities. It answers the question of whether there are difficulties attached to the discontinuities identified, and if so, whether the research proposes means to reduce the gap – to create a transition. The book concludes with directions for future research on transitions in mathematics education.

It includes topics of great current interest such as semiclassical theory, chaos and Bose-Einstein condensation in atomic gases. The third edition of Theoretical Atomic Physics extends the successful second edition with a detailed treatment of the wave motion of atoms near the anticlassical or extreme quantum regime, and it also contains an introduction to some aspects of atom optics that are relevant for current and future experiments involving ultra-cold atoms. Various problems are included together with complete solutions. Because it has more emphasis on theory, this book enables the reader to appreciate the fundamental assumptions underlying standard theoretical constructs and to embark on independent research projects.
The Stability of Matter : From Atoms to Stars Selecta of Elliott H. Lieb
This collection of papers -- starting with a brilliant article by one of the masters of the field -- gives an excellent current review of our knowledge of matter. Partially basing his own work on a variational formulation of quantum mechanics, E.H. Lieb links the difficult question of the stability of matter with important problems in functional analysis. Here the reader will find general results together with deep insights into quantum systems combined with papers on the structure of atoms and molecules, the thermodynamic limit, and stellar structures. The book is suitable as an accompanying text or recommended reading for a graduate course in quantum mechanics. In the third edition, two new sections were added: one contains papers on quantum electrodynamics, and the other on Boson systems. In this fourth edition, these topics have been further developed, extending the book by approximately 120 pages.
The Self-Marginalization of Wilhelm Stekel : Freudian Circles Inside and Out
As both an early disciple of and influence on Freud, Wilhelm Stekel enjoyed a unique position within the analytic movement. More recently, he has been notable more for his ostracism from Freud’s sphere and little else. The Self-Marginalization of Wilhelm Stekel brings a fresh perspective on Stekel, revealing the complex, symbiotic bond between mentor and follower in its many social, interpersonal, and psychological forms.In addition to shedding light on a famous outsider, this biography is set in a dual context of the formative years of psychoanalysis and Freud’s relationships with his colleagues: comparisons and contrasts abound with Adler, Jung, and other, revered exiles from Freudian circles. At the same time, each chapter defines and identifies a particular aspect of the marginalization process, including self-marginalization, the relationship of marginals to the mainstream, and the value of marginalization in the construction of identity.
The Robosapien Companion : Tips, Tricks, and Hacks

The Kaiser's Mosques : Islamic Architecture and Orientalizing Style in Habsburg Bosnia, 1878–1918
Highlights an understudied experiment at the intersection of 19th-century European and Islamic architectural histories. It draws attention to a body of buildings designed by architects trained in Central Europe for use by Muslims in Habsburg ruled Bosnia-Herzegovina (1878-1918). They include mosques, madrasas, and other buildings corresponding to a traditional Islamic formal and functional typology. The composition and decoration, however, is the product of 19th-century European His toricist conduct. It became a prominent style for town halls and private residences; on occasion, it was also used for railway stations, schools, or hotels. The spread and concentration of buildings in this style in Bosnia is extraordinary. This monography not only fills a gap in an art history that has long turned a blind eye to Europe’s Southeast but also contributes to our understanding of European powers’ historical responses to the challenge of cultural diversity in territories under their control.
