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.
Superpositions of periodic dot screens are largely used in electronic imaging in the field of color printing. In such superpositions the interaction between the superposed layers may cause new structures to appear which did not exist in any of the original ...
The integration of sample pretreatment into microfluidic devices represents one of the remaining hurdles towards achieving true miniaturized total analysis systems (μTAS). The challenge is made more complex by the enormous variation in samples to be analyz ...
A brief review with 18 refs. is provided of the principal research and development activities of the Lab. of Polyelectrolytes and BioMacromols. at the Swiss Federal Institute of Technol. These include, in particular, the synthesis of tailor-made polyelectr ...
We propose an algorithm for the 3-D reconstruction of DNA filaments from a pair of stereo cryo-electron micrographs. The underlying principle is to specify a 3-D model of a filament—described as a spline curve—and to fit it to the 2-D data using a snake-li ...
In this paper, we intend to gain an understanding of the interaction of light with microstructures. Measurements of amplitude and phase in the diffracted field close to gratings using a heterodyne scanning probe are presented. Coherent light diffracted by ...
A review, with refs. When mentioning prokaryotic metabolic engineering, most people will immediately think of Jay Bailey. Jay's contribution to this fast-growing field is evident and familiar to many. Therefore, instead of a detailed tech. review, we attem ...
In this paper we compute the relative class number of all imaginary Abelian fields of prime conductor below 10000. Our approach is based on a novel multiple evaluation technique, and, assuming the ERH, it has a running time of O(p2 log 2(p) log log (p)), w ...
The most important advances in the field of biomaterials over the past few years have been in bioactive biomaterials. Materials have been developed to incorporate bioactivity through biological recognition, including incorporation of adhesion factors, poly ...
Application of a direct elec. field in contaminated soils is expected to produce an important in situ means of environmental restoration. The factors that det. the success of the process are the combined effects of electroosmosis, ionic migration, electroc ...
