101 Hansen, Charles D.Parallel lumigraph reconstructionThis paper presents three techniques for reconstructing Lumigraphs/Lightfields on commercial ccNUMA parallel distributed shared memory computers. The first method is a parallel extension of the software-based method proposed in the Lightfield paper. This expands the ray/two-plane intersection test a...Lumigraph; Lightfield; Illumination; Parallel reconstruction; Ray tracing1999
102 Parker, Steven G.; Hansen, Charles D.; Shirley, Peter S.Parallel methods for isosurface visualizationisosurface extraction and vis utilization is crucial for explorative scientific visualization of extremely large scientific data. The shear number of polygons extracted and the subsequent rendering time limit interactivity. We explore two solutions to this problem: exploiting parallel graphics hardw...Isosurfaces; Ray tracing; Large data1999
103 Brunvand, Erik L.Peephole optimization of asynchronous macromodule networksAbstract- Most high-level synthesis tools for asynchronous circuits take descriptions in concurrent hardware description languages and generate networks of macromodules or handshake components. In this paper, we propose a peephole optimizer for these networks. Our peephole optimizer first deduces an...1999
104 Freire, JulianaPersonalizing the web using site descriptionsThe information overload on the Web has created a great need for efficient filtering mechanisms. Many sites (e.g., CNN and Quicken) address this problem by allowing a user to create personalized pages that contain only information that is of interest to the user. We propose a new approach for p...XPointer; Data extraction; Site descriptions; Personalized web pages1999
105 Maloney, Thomas N.Personnel policy, costs of experimentation, and racial inequality in the Pre-World War II NorthBetween 1910 and 1940, the black population of the northern United States nearly tripled, rising from just over I million to more than 2.7 million, signaling the start of the "Great Migration" of African-Americans out of the South. As black workers entered the North, they sought positions in new sec...Race bias; Personnel policies; African Americans; Employment opportunities1999
106 Bohs, Lynn A.Phylogeny and provisional classification of the Solanaceae based on chloroplast DNAA phylogenetic analysis of the Solanaceae based on chloroplast DNA variation is presented.

107 Mallon, RonaldPolitical liberalism, cultural membership and the familyIn a recent article on developments in John Rawls's theory of justice, S.A. Lloyd notes a problem in Rawls's treatment of the family. In Political Liberalism (hereafter PL), Rawls concedes that his theory assumes that "in some form the family is just." And Lloyd takes this to mean that the principle...Theory of justice; Equality; Upbringing1999
108 Brunvand, Erik L.Practical advances in asynchronous design and in asynchronous/synchronous interfacesAsynchronous systems are being viewed as an increasingly viable alternative to purely synchronous systems. This paper gives an overview of the current state of the art in practical asynchronous circuit and system design in four areas: controllers, datapaths, processors, and the design of asynchr...1999

110 Schaelicke, LambertProfiling I/O interrupts in modern architecturesAs applications grow increasingly communication-oriented, interrupt performance quickly becomes a crucial component of high performance I/O system design. At the same time, accurately measuring interrupt handler performance is difficult with the traditional simulation, instrumentation, or statistica...1999
111 Couldwell, William T.Prolactinomas: focus on indications, outcomes and management of recurrencesAlthough prolactinomas are discovered at autopsy with equal frequency in women and men, they present clinically in women far more often than in men. In children, "in whom they are the most common type of adenoma, prolactinomas are seen more often in girls than in boys. In a series of nearly 400 PRL...Outcome; Pituitary adenoma; Prognosis; Prolactin; Transsphenoidal surgery1999
112 Gopalakrishnan, Ganeshpsolve: Deciding satisfiability for presburger formulae using automata, rewriting and a model checkerPresburger formulas are an expressive but decidable language of arithmetic expressions and boolaen connectives with quantification. psolve is a prototype of an automata based tool for deciding the satisfiability of Presburger formulae extended with a predicate that recognizes powers of two. The uniq...psolve; Presburger formulas; Satisfiability; Automata; Rewriting; Model checker1999
113 Beckerle, Mary C.Purification and characterization of an α-actinin-binding PDZ-LIM protein that is up-regulated during muscle differentiationα-Actinin is required for the organization and function of the contractile machinery of muscle. In order to understand more precisely the molecular mechanisms by which α-actinin might contribute to the formation and maintenance of the contractile apparatus within muscle cells, we performed a scree...LIM domains; Z-disc; Actin; Actinin-associated LIM proteins; PDZ-LIM protein1999

118 Clayton, Dale H.Reciprocal natural selection on host-parasite phenotypesCoevolution is evolution in one species in response to selection imposed by a second species, followed by evolution in the second species in response to reciprocal selection imposed by the first species. Although reciprocal selection is a prerequisite of coevolution, it has seldom been documented in...Host-parasite phenotypes; Ectoparasites; Virulence; Fitness1999
