Abstract: The invention relates to an optical device for measuring the position of an object along a first axis, the object being subjected to light radiations emitted by a light source.

Abstract: The present invention relates to a method of preparation of substrates for nucleic acid sequencing reactions. More specifically, the present invention provides a new method of preparing hairpins using force-induced strand invasion. Hairpins prepared by this method and methods of nucleic acid analysis using these hairpins are also part of the present invention.

Abstract: The invention is related to a digital-data mixing apparatus (2), a data processing system (1) and an associated method for mixing digital-data. The digital-data mixing apparatus comprises, integrated in a housing (7), input means (8) for receiving a plurality of bits (I1 . . . In) of input digital data (4), electromagnetic emission means (9) for generating a modulated electromagnetic beam (15) wherein said input digital data (4) are converted in simultaneous modulations of the modulated electromagnetic beam (15), electromagnetic scattering means (10) for scattering the modulated electromagnetic beam (15) in a scattered electromagnetic beam (19), receiving means (11) for converting the scattered electromagnetic beam (19) in bits (O1 . . . Om) of output digital data (5), and output means (12) for providing said output digital data (5).

Abstract: The invention relates to an optical device for measuring the position of an object along a first axis, the object being subjected to light radiations emitted by a light source.

Abstract: A method for producing a metal fluoride ceramic, comprising: providing a sedimented compound comprising metal fluoride particles having an average particle size lower than 30 nm and a solvent, partially drying the sedimented compound at a temperature lower than 65° C. until the partially dried compound comprises from 5 wt % to 45 wt % of the solvent, and sintering, for example in air, the partially dried and sedimented compound.
