Type theory Operational semantics. Gregor Kiczales is an American computer scientist. He is currently a full time professor of computer science at the University of British Columbia in Vancouver, British Columbia, Canada.
He is best known for developing the concept of aspect-oriented programming, and the AspectJ extension to the Java programming language, both of which he designed while working at Xerox PARC.
Gordon David Plotkin , is a theoretical computer scientist in the School of Informatics at the University of Edinburgh. Plotkin is probably best known for his introduction of structural operational semantics SOS and his work on denotational semantics.
He has contributed to many other areas of computer science. Philip Lee Wadler is an American computer scientist known for his contributions to programming language design and type theory. In particular, he has contributed to the theory behind functional programming and the use of monads in functional programming, the design of the purely functional language Haskell, and the XQuery declarative query language.
In , he created the Orwell programming language. Wadler was involved in adding generic types to Java 5. He is also author of the paper Theorems for free! Until June 30, , she was Corporate Vice President of Microsoft Research with oversight of its core research laboratories around the world and Microsoft Research Connections. Born in Britain, as of he lives in the United States, although he remains a British citizen. Oscar Peter Buneman , is a British computer scientist who works in the areas of database systems and database theory.
Georg Gottlob FRS is an Austrian computer scientist who works in the areas of database theory, logic, and artificial intelligence and is Professor of Informatics at the University of Oxford. Michael Ralph Stonebraker is a computer scientist specializing in database research. Through a series of academic prototypes and commercial startups, Stonebraker's research and products are central to many relational database systems.
He is also an editor for the book Readings in Database Systems. Peter A. Wegner was a computer scientist who made significant contributions to both the theory of object-oriented programming during the s and to the relevance of the Church—Turing thesis for empirical aspects of computer science during the s and present. In , Wegner wrote a brief autobiography for Conduit , the annual Brown University Computer Science department magazine.
Laurie Hendren was a Canadian computer scientist noted for her research in programming languages and compilers. Dahlia Malkhi is an Israeli-American computer scientist who works on distributed systems. She is now working at Novi Financial as a lead researcher, and she is the lead maintainer of the Libra project.
Venkata Narayana Padmanabhan is a computer scientist and principal researcher at Microsoft Research India. He is known for his research in networked and mobile systems.
These bits permit to trace effects of interactions, but not to the point of being able to identify the precise molecule that caused an effect.
The algebra and the causal hints match a particular form of DNA computation. Molecular Semantics. The semantics of programming languages is based on states and state transitions, through which one can study for example termination, nodeterminism, and concurrency.
Adding rates to transitions induces quantitative meanings that can be related to stochastic and continuous dynamical systems, and to their realizations as molecular systems.
Biological Models Transport Papers. At the core of the biochemical networks that regulates the cell cycle there is a switch that triggers an irreversible transition from one critical stage of cell division to the next. Its dynamical system behavior is fairly well understood, and could be achieved by many different networks. But in nature, from yeast to us, we find a specific universal structure of the network: what is special about this structure, beyond its required function?
To answer this question we shift our perspective from dynamical systems to computing systems. We ask: what does the cell cycle switch compute, and how does it compute it?
Organisms employ a variety of signalling systems to sense and react to their environment. Among the most basic, commonly found in bacteria, lower eukaryotes and plants, are the so-called phosphorelays. These systems transfer sensor information typically from the cellular membrane very economically through a chain of chemical reactions. Despite their widespread use and simple architecture, we are still far from a full understanding of the signal-processing capabilities of phosphorelays.
