The program dependence graph and its use in optimization

by Jeanne Ferrante, Karl J. Ottenstein, Joe D. Warren - ACM Transactions on Programming Languages and Systems , 1987
"... In this paper we present an intermediate program representation, called the program dependence graph (PDG), that makes explicit both the data and control dependence5 for each operation in a program. Data dependences have been used to represent only the relevant data flow relationships of a program. ..."

incremental optimization, permitting transformations to be triggered by one another and applied only to affected dependences.

Brain magnetic resonance imaging with contrast dependent on blood oxygenation.

by S Ogawa , T M Lee , A R Kay , D W Tank - Proc. Natl. Acad. Sci. USA , 1990
"... ABSTRACT Paramagnetic deoxyhemoglobin in venous blood is a naturally occurring contrast agent for magnetic resonance imaging (MRI). By accentuating the effects of this agent through the use of gradient-echo techniques in high fields, we demonstrate in vivo images of brain microvasculature with imag ..."

with image contrast reflecting the blood oxygen level. This blood oxygenation level-dependent (BOLD) contrast follows blood oxygen changes induced by anesthetics, by insulininduced hypoglycemia, and by inhaled gas mixtures that alter metabolic demand or blood flow. The results suggest that BOLD contrast can

Using Daily Stock Returns: The Case of Event Studies

by Stephen J. Brown, Jerold B. Warner - Journal of Financial Economics , 1985
"... This paper examines properties of daily stock returns and how the particular characteristics of these data affect event study methodologies. Daily data generally present few difficulties for event studies. Standard procedures are typically well-specified even when special daily data characteris-tics ..."

Financial Intermediation, Loanable Funds, and the Real Sector

by Bengt Holmstrom, Jean Tirole - Quarterly Journal of Economics , 1997
"... We study an incentive model of ®nancial intermediation in which ®rms as well as intermediaries are capital constrained. We analyze how the distribution of wealth across ®rms, intermediaries, and uninformed investors affects investment, interest rates, and the intensity of monitoring. We show that al ..."

Multimarket Oligopoly: Strategic Substitutes and complements

by Jeremy I. Bulow, John D. Geanakoplos, Paul D. Kiemperer - JOURNAL OF POLITICAL ECONOMY
"... A firm’s actions in one market can change competitors’ strategies in a second market by affecting its own marginal costs in that other mar-ket. Whether the action provides costs or benefits in the second market depends on (a) whether it increases or decreases marginal costs in the second market and ..."

Labor Contracts as Partial Gift Exchange

by George A. Akerlof - Quarterly Journal of Economics , 1982
"... This paper explains involuntary unemployment in terms of the response of firms to workers ' group behavior. Workers ' effort depends upon the norms determining a fair day's work. In order to affect those norms, firms may pay more than the market-clearing wage. Industries that pay cons ..."

Normalization for cDNA microarray data: a robust composite method addressing single and multiple slide systematic variation

by Yee Hwa Yang, Sandrine Dudoit, Percy Luu, Vivian Peng , 2002
"... There are many sources of systematic variation in cDNA microarray experiments which affect the measured gene expression levels (e.g. differences in labeling efficiency between the two fluorescent dyes). The term normalization refers to the process of removing such variation. A constant adjustment is ..."

Range-Free Localization Schemes for Large Scale Sensor Networks

by Tian He, Chengdu Huang, Brain M. Blum, John A. Stankovic, Tarek Abdelzaher , 2003
"... Wireless Sensor Networks have been proposed for a multitude of location-dependent applications. For such systems, the cost and limitations of hardware on sensing nodes prevent the use of range-based localization schemes that depend on absolute point-to-point distance estimates. Because coarse accura ..."

Reliable Communication in the Presence of Failures

by Kenneth P. Birman, Thomas A. Joseph - ACM Transactions on Computer Systems , 1987
"... The design and correctness of a communication facility for a distributed computer system are reported on. The facility provides support for fault-tolerant process groups in the form of a family of reliable multicast protocols that can be used in both local- and wide-area networks. These protocols at ..."

attain high levels of concurrency, while respecting application-specific delivery ordering constraints, and have varying cost and performance that depend on the degree of ordering desired. In particular, a protocol that enforces causal delivery orderings is introduced and shown to be a valuable

A theory of social comparison processes,”

by Leon Festinger - Human Relations, , 1954
"... In this paper we shall present a further development of a previously published theory concerning opinion influence processes in social groups (7). This further development has enabled us to extend the theory to deal with other areas, in addition to opinion formation, in which social comparison is i ..."
