Abstract: There are provided solutions for multiagent debate. In a method, a first and a second response representation are determined by a first and a second agent in a plurality of agents based on a first query representation for a query in a natural language, respectively, and the first and second response representations are convertible to a first and a second answer to the query in the natural language, respectively. A second query representation is obtained based on the first query representation, and at least one of the first and second response representations. A response representation is determined based on the second query representation by at least one of the first and second agents, and the response representation is convertible to an answer to the query in the natural language. These agents communicate in an embedding space without a conversion between a natural language format and an embedding format.

Abstract: A device which can be implanted in the body and comprises an electrically conducting support covered with a layer of electrically conducting polymer, to which layer is attached at least one biologically active substance of an anionic or cationic nature. The deposition of the polymer is carried out, in a first stage, by electropolymerization directly directly on the support or, according to an alternative form, by deposition of the polymer in solution on the support. In a second stage, electrochemical oxidation or reduction is conducted and the biologically active substance with an anionic or cationic nature is attached to the polymer.

Abstract: The polymer films of the invention contain reactive groups and are obtained from phenols of the formula ##STR1## in which R denotes an acyl group with 1 to 7 carbon atoms, a hydroxy, carboxy, alkoxycarbonyl, amino, alkylamino or phenylamino group, andn is an integer, which may be 0 in the case where R is an acyl group.The films are prepared by electrolytic polymerisation on metallic surfaces and can be used to graft various materials reacting therewith, as intermediate layers.
