A congruence for gamma programs [chapter]

Lindsay Errington, Chris Hankin, Thomas Jensen
1993 Lecture Notes in Computer Science  
This paper de nes a congruence relation on Gamma programs. Based on this congruence relation, laws for transforming programs are derived.  ...  We de ne an axiomatic semantics for Gamma based on Brookes' transition assertions. The de nition of the congruence is in terms of provable satis ability of such assertions.  ...  We showed that the relation forms a pre-congruence for Gamma programs which has the important consequence that program transformation can be done locally.  ...

Problems in rewriting applied to categorical concepts by the example of a computational comonad [chapter]

Wolfgang Gehrke
1995 Lecture Notes in Computer Science  
We present a canonical system for comonads which can be extended to the notion of a computational comonad BG92] where the crucial point is to nd an appropriate representation.  ...  Finally we outline an incomplete attempt to solve the problem which could be used as a benchmark for rewriting tools.  ...  Acknowledgments I am indebted to Frank Pfenning for his hospitality during a visit to CMU which made it possible to learn more about the programming language Elf and which allowed me fruitful discussions  ...

Implicit agency is related to gamma power changes in an automatic imitation task [article]

José Luis Ulloa, Roberta Vastano, Ole Jensen, Marcel Brass
2021 bioRxiv   pre-print
We observed a decrease of alpha, beta and gamma power for congruent compared to incongruent actions and increased theta power for incongruent compared to congruent actions.  ...  Our study suggests that an increased implicit agency for facilitated actions is associated with changes in gamma power.  ...  This again highlights the role that gamma oscillations can have for monitoring and updating 455 motor programs, in complement to theta oscillations.  ...

Gamma can also be seen as a notation for coordinat- ing independent programs in a larger application.  ...  In this paper, we study a notion of refinement for programs involving parallel and sequential composition operators, and derive a number of programming laws.  ... 

On the Linear Combination of Exponential and Gamma Random Variables

Saralees Nadarajah, Samuel Kotz
2005 Entropy  
A measure of entropy of the linear combination is investigated. We also provide computer programs for generating tabulations of the percentage points associated with the linear combination.  ...  The exact distribution of the linear combination αX + βY is derived when X and Y are exponential and gamma random variables distributed independently of each other.  ...  Acknowledgments The authors would like to thank the referees and the editor for carefully reading the paper and for their great help in improving the paper.  ...

The TyrA family of aromatic-pathway dehydrogenases in phylogenetic context

Jian Song, Carol A Bonner, Murray Wolinsky, Roy A Jensen
2005 BMC Biology  
Phylogenetic relationships of TyrA domains were evaluated in the context of combinatorial patterns of specificity for the two substrates, as well as the presence or absence of a variety of fusions.  ...  Interactive alignments for a suite of catalytic-core TyrA domains of differing specificity are also provided to facilitate phylogenetic analysis. tyrA membership in apparent operons (or supraoperons) was  ...  This analysis would not have been possible were it not for the yeoman efforts in comparative enzymology carried out over a period of more than 25 years by many students and postdoctoral fellows, most notably  ...

Detecting phylogenetic incongruence using BIONJ: an improvement of the ILD test

Marina Zelwer, Vincent Daubin
2004 Molecular Phylogenetics and Evolution  
The problem of testing for congruence between phylogenetic data has long been debated among phylogeneticists, but reaches a critical point with the availability of large amount of biological sequences.  ...  The incongruence length difference test (ILD), based on parsimony, has been proved to be useful for finding incongruent data sets, but its application remains limited to small data sets for computational  ...  Acknowledgments We thank Marie-France Sagot, Christian Gautier, Manolo Gouy, and two anonymous reviewers for their useful comments and remarks.  ...
