Discrete structures

"This book is clearly written and presents a large number of examples illustrating the theory . . . there is no other book of comparable content available. Because of its detailed coverage of applications generally neglected in the literature, it is a desirable if not essential addition to undergraduate mathematics and computer science libraries.

This paper introduces new learning algorithms for natural language processing based on the perceptron algorithm. We show how the algorithms can be efﬁciently applied to exponential sized representations of parse trees, such as the “all subtrees” (DOP) representation described by (Bod 1998), or a representation tracking all subfragments of a tagged sentence. We give experimental results showing signiﬁcant improvements on two tasks: parsing Wall Street Journal text, and namedentity extraction from web data. ...

DWTs are constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multiscale analysis. This is avoided in biorthogonal discrete wavelet transform (BDWT) algorithms, where the scaling and wavelet filters are symmetric and linear phase. The biorthogonal filters are usually constructed by a laddertype network called lifting scheme.

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic[1] – do not vary smoothly in this way, but have distinct, separated values.

We prove the Bers density conjecture for singly degenerate Kleinian surface groups without parabolics. 1. Introduction In this paper we address a conjecture of Bers about singly degenerate Kleinian groups. These are discrete subgroups of PSL2 C that exhibit some unusual behavior: • As groups of projective transformations of the Riemann sphere C they act properly discontinuously on a topological disk whose closure is all of C. • As groups of hyperbolic isometries their action on H3 is not convex cocompact. ...

The modelling of mechanical systems provides engineers and students with the methods to model and understand mechanical systems by using both mathematical and computerbased tools. Written by an eminent authority in the field, this is the second of four volumes which provide engineers with a comprehensive resource on this cornerstone mechanical engineering subject. Dealing with continuous systems, this book covers solid mechanics, beams, plates and shells.

THE recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signaltonoise ratio has intensified the interest in a general theory of communication. A basis for such a theory is contained in the important papers of Nyquist1 and Hartley2 on this subject. In the present paper we will extend the theory to include a number of new factors, in particular the effect of noise in the channel, and the savings possible due to the statistical structure of the original message and due to the nature of the final destination of the information....

Here we study the architecture and characteristics of the broker network. We are using a particular internal structure for the events (deﬁned in XML but currently implemented as a Java object). We assume a sophisticated matching of publishers and subscribers deﬁned as general topic objects (deﬁned by an XML Schema that we have designed). However these are not the central issues to be discussed here.

In this chapter, we study the mathematical structure of a simple oneperiod model of a financial market. We consider a finite number of assets. Their initial prices at time t = 0 are known, their future prices at time t = 1 are described as random variables on some probability space. Trading takes place at time t = 0. Already in this simple model, some basic principles of mathematical finance appear very clearly. In Section 1.2, we single out those models which satisfy a condition of market efficiency: There are no trading opportunities which yield a profit without any downside risk.

Search algorithms aim to find solutions or objects with specified properties and constraints in a large solution search space or among a collection of objects. A solution can be a set of value assignments to variables that will satisfy the constraints or a substructure of a given discrete structure. In addition, there are search algorithms, mostly probabilistic, that are designed for the prospective quantum computer.

The heterogeneous nuclear ribonucleoprotein (hnRNP) type I, a modulator of alternative splicing, localizes in the nucleoplasm of mammalian cells and in a discrete perinucleolar structure. HnRNP I contains a novel type of bipartite nuclear localization signal (NLS) at the Nterminus of the protein that we have previously named nuclear determinant localization type I (NLDI). Recently, a neural counterpart of hnRNP I has been identiﬁed that contains a putative NLS with two strings of basic amino acids separated by a spacer of 30 residues....

The word metabolism derives from the Greek word for “change.” Metabolism represents the sum of the chemical changes that convert nutrients, the “raw materials” necessary to nourish living organisms, into energy and the chemically complex finished products of cells. Metabolism consists of literally hundreds of enzymatic reactions organized into discrete pathways.

Among the components of the limbic system, the amygdala is a fascinating structure that is involved in the processes of liking and disliking and in the ways our emotions drive our actions and affect the strength of our memories. Combined with new conceptual breakthroughs, the very latest data obtained by leading world experts in amygdala function that are reviewed in this book have helped to understand how the amygdala contribute to these processes and also to a variety of neurological and neuropsychiatric pathologies....

Analysis of a draft nuclear genome sequence of the diatomThalassiosira pseudonana revealed the presence of 11 open reading frames showing significant similarity to functionally characterized fatty acid frontend desaturases. The corresponding genes occupy discrete chromosomal locations as determined by comparison with the recently published genome sequence. Phylogenetic analysis showed that two of the T. pseudonana desaturase (Tpdes) sequences grouped with proteobacterial desaturases that lack a fused cytochrome b5 domain. ...

The shipping industry is both special and fascinating. It is special, above all, because of its truly global nature, the huge discrete investments needed, the highly cyclical markets at play, and the unique competitive structure, with many determined players. It is fascinating, above all, because fortunes are made—and lost—at a fast pace, with some of the most riskwilling owners also serving as decision makers. This book is the result of at least seven forces that have shaped my interest in shipping corporations and their strategies. The first is purely personal.
