Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Market Sharing Dynamics Between Two Service Providers

Max-Olivier Hongler, Olivier Gallay

We study the market partition between two distinct firms that deliver services to waiting-time sensitive customers. In our model, the incoming customers select a firm on the basis of its posted price, the expected waiting time and its brand. More specifica ...

Changing the substrate specificity of cytochrome c peroxidase using directed evolution

Kai Johnsson, Petra Tafelmeyer

Cytochrome c peroxidase (I) from Saccharomyces cerevisiae was subjected to directed mol. evolution to generate mutants with increased activity against ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)]. Using a combination of DNA shuffling and s ...

Evolutionary approaches to study cytochrome c peroxidase

Kai Johnsson, Petra Tafelmeyer

A review with 15 refs. Directed mol. evolution of enzymes and proteins has emerged as an extremely powerful method to create proteins with novel properties, both for practical applications as well as for mechanistic studies. To demonstrate the underlying p ...

Directed molecular evolution of cytochrome c peroxidase

Kai Johnsson, Petra Tafelmeyer

Cytochrome c peroxidase (CCP) from Saccharomyces cerevisiae was subjected to directed mol. evolution to generate mutants with increased activity against the classical peroxidase substrate, guaiacol, thus changing the substrate specificity of CCP from the p ...

In-situ OH kinetics study providing an indicator for ozone formation limitation

Hubert van den Bergh, Bertrand Calpini, Alain Clappier

Hydroxyl radicals dominate daytime tropospheric chem., responsible for reactive removal of most trace gases (e.g., volatile org. compds.[VOC]), and is an active participant in the NO and NO2 cycle. Pump-and-probe LIDAR was used to examine the OH- chem. in ...

Learning and Evolution

Dario Floreano

In the last few years several researchers have resorted to artificial evolution (e.g. genetic algorithms) and learning techniques (e.g. neural networks) for studying the interaction between learning and evolution. These studies have been conducted for two ...

Co-evolving predator and prey robots: Do 'arm races' arise in artificial evolution?

Dario Floreano

Co-evolution (i.e. the evolution of two or more competing populations with coupled fitness) has several features that may potentially enhance the power of adaptation of artificial evolution. In particular, as discussed by Dawkins and Krebs [3], competing p ...

How co-evolution can enhance the adaptation power of artificial evolution: Implications for evolutionary robotics

Dario Floreano

Co-evolution (i.e. the evolution of two or more competing populations with coupled fitness) has several interesting features that may potentially enhance the power of adaptation of artificial evolution. In particular, as discussed by Dawkins and Krebs [2], ...

The evolution of 'bricolage'

Denis Duboule

The past ten years of developmental genetics have revealed that most of our genes are shared by other species throughout the animal kingdom. Consequently, animal diversity might largely rely on the differential use of the same components, either at the ind ...

Generation of tripolar vortical structures on the beta plane

Jan Sickmann Hesthaven

A new feature of the long-time evolution of a strong vortex with initially monotonic potential vorticity is found by direct numerical solution of the quasigeostrophic equivalent barotropic equation. Two satellites, which emerge after splitting of an annulu ...
