We investigate present some new statistical properties of order books. We analyse data from the Nasdaq and investigate (a) the statistics of incoming limit order prices, (b) the shape of the average order book, and (c) the typical life time of a limit order as a function of the distance from the best price. We also determine the ‘price impact’ function using French and British stocks, and find ...

During the past dozen years, a major focus of my research has been the spectral theory of orthogonal polynomials—both orthogonal polynomials on the real line (OPRL) and on the unit circle (OPUC). There has been a flowering of the subject in part because of a cross-fertilization of two communities of researchers. I will discuss some aspects of this subject here; for a lot more, see my recent boo...

Someone once observed that every decade the real estate industry invents a new vehicle for wealth transfer between the inventors and their investors. During my career we have seen this drama play out many times. New wrinkles in capital markets often lead to disheveled portfolios. In the mid 1970s, major banks seized on the mortgage real estate investment trust (REIT) as a vehicle to make loans ...

vertebrates. Throughout the book experimental findings fundamental to the understanding of specific functions are discussed. The chapters are well illustrated and include a carefully selected list of books, papers, and review articles. On the whole, this is a textbook of high quality which should be of value to those interested in physiological processes from a comparative and adaptive point of...

1. Introduction In a recent profile of James Meade, Max Corden (1996) writes, "Most students, and possibly many readers of this review, know the theory of internal and external balance through the Swan diagram and believe that Swan originated this theory or approach. They are also likely to believe that the 'theory of domestic distortions' originated with Bhagwati in various writings, especiall...

We present a new method for rendering silhouettes of point-based models. Due to the lack of connectivity information, most existing polygon-based silhouette generation algorithms cannot be applied to point-based models. Our method not only bypasses this connectivity requirement, but also accommodates point-based models with sparse non-uniform sampling and inaccurate/no normal information. Like ...

From the historical point of view, the article by Box and Wilson [1] is considered to be the first for having laid the foundations for RSM. Some of the early papers that also contributed to the development of RSM include those by Box and Hunter [2] and Box and Draper [3]. Several review papers on RSM were subsequently published starting with the article by Hill and Hunter [4] that emphasized pr...

We study serial coalgebras by means of their valued Gabriel quivers. In particular, Hom-computable and representation-directed coalgebras are characterized. The Auslander-Reiten quiver of a serial coalgebra is described. Finally, a version of Eisenbud-Griffith theorem is proved, namely, every subcoalgebra of a prime, hereditary and strictly quasi-finite coalgebra is serial. Introduction A syste...

A permanent physical fault in communication lines usually leads to a failure. The feasibility of evolution of a self organized communication is studied in this paper to defeat this problem. In this case a communication protocol may emerge between blocks and also can adapt itself to environmental changes like physical faults and defects. In spite of faults, blocks may continue to function since ...

2 Foreword This textbook provides study materials for the participants of the course named Multivariate Analysis of Ecological Data that we teach at our university for the third year. Material provided here should serve both for the introductory and the advanced versions of the course. We admit that some parts of the text would profit from further polishing, they are quite rough but we hope in ...
