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.
The core dynamics of the Stokes eigenmodes subjected to satisfy no-slip boundary conditions on any 2D closed contour, or 3D surface, is shown to be characterized by a linear differential functional relationship between the vector potential and vorticity, $ ...
Cysteine-dependent aspartic proteases (caspases) are a family of enzymes which play a crucial role in apoptosis. Caspases accumulate in eukaryotic cells in the form of low-activity proenzyme precursors. Proteolytic cleavage of specific sites triggers confo ...
The gene Rv0813c from Mycobacterium tuberculosis, which codes for a hypothetical protein of unknown function, is conserved within the order Actinomycetales but absent elsewhere. The crystal structure of Rv0813c reveals a new family of proteins that resembl ...
Cripto is a glycosylphosphatidylinositol (GPI)-anchored co-receptor of Nodal and several other transforming growth factor-beta (TGF-beta) family ligands. It contains an epidermal growth factor (EGF)-like motif and a Cripto-FRL1-Cryptic (CFC) domain, which ...
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 ...
Processes at the surface of Plasmodium falciparum-infected erythrocytes such as antigenic variation and cytoadhesion may be modulated by active signalling between host and parasite. Potential candidates for this role include the putative kinases of the FIK ...
Combinatorial mutagenesis was used to investigate the role of three key residues in cytochrome c peroxidase (CCP) from Saccharomyces cerevisiae, Arg48, Trp51, and Trp191, in control of the reactivity and selectivity of the heme-contg. enzyme. Libraries wer ...
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 ...
Network Calculus is a set of recent developments, which provide a deep insight into flow problems encountered in networking. It can be viewed as the system theory that applies to computer networks. Contrary to traditional system theory, it relies on max-pl ...
This paper presents a new image representation method based on anisotropic refinement. It has been shown that wavelets are not optimal to code 2-D objects which need true 2-D dictionaries for efficient approximation. We propose to use rotations and anisotr ...
