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.
In order to better understand the sources of numerical instabilities occurring in the simulation of time-dependent flows of viscoelastic fluids at high Weissenberg numbers, we have used various types of linear stability analyses. In complement to the limit ...
The reactivity of various 2-oxyallyl cations toward 2,2'-methylenedifuran (1b), 2,2'-(hydroxymethyl)difuran (1c), 2,2'-(trimethylsilylmethylene)difuran (1d), and di(2-furyl)methanone (1e) has been explored. Difuryl derivatives 1c, 1d, and le refused to und ...
Starting from 2,2'-methylenedifuran, enantiomerically enriched (98%) (3R,5S,7R,9S,11R,13R)- and (3R,5S,7S,9R,11R,13R)-15-amino-5,7,9,11-tetrahydroxy-3,13-bis(4-methoxyb enzoyloxy)pentadec-1-yl) pivalate were prepared as well as (3R,5R,7R,9R,11S,13S)-1,15-d ...
We propose to design the reduction operator of an image pyramid so as to minimize the approximation error in the lp-sense (not restricted to the usual p=2), where p can take non-integer values. The underlying image model is specified using shift- ...
In this paper, we present a new approach to incorporating multiple time scale information as independent streams in multi-stream processing. To illustrate the procedure, we take two different sets of multiple time scale features. In the first system, these ...
Radical C-glycosidation of a 3-methylidene-7-oxabicyclo[2.2.1]heptan-2-one derivative with acetobromomannose gave a alpha-C-mannopyranoside that was converted into alpha-D-ManpCH(2)(1-->3)-D-GalNAc, a C-disaccharide that inhibits beta-galactosidase from ja ...

Cycloaddition of 1,3-dibromo-2-oxyallyl cation to 2-(benzyloxymethyl)furan provided a 8-oxabicyclo[3.2.1]hept-6-en-3-one derivative that was transformed into (2RS,3SR,4SR,5SR,6SR)-3,4-dibromo-2-benzyloxymethyl-2,6-bis(hydroxymethy l)-4- (methoxymethyloxy)t ...
The analysis of incommensurate structures is computationally more difficult than that of normal ones. This is mainly a result of the structure-factor expression, which involves numerical integrations or infinite series of Bessel functions. Both approaches ...
A collection of (2R,3R,4S)-3,4-dihydroxypyrrolidin-2-yl derivatives have been tested for their inhibitory activities toward 25 glycosidases. Competitive (K-i=7.4 VM) and selective inhibition of alpha -mannosidase from jack bean has been found for (2R,3R,4S ...
