摘要： A dual-frequency-comb spectrometer and a method for spectroscopic investigation of a sample are described. The spectrometer includes first and second frequency comb devices for emitting laser pulses along first and second light paths, wherein the repetition frequency of the laser pulses emitted by the second device is offset from that of the first device. First and second multi-core waveguides including at least two separate single core waveguides having field-coupling via a coupling gap therebetween are arranged in the first and second light paths. The sample is irradiated by the second frequency comb in the second light path. A detector device is arranged in a third light path where the first and second light paths are combined, for simultaneously sensing the first frequency comb and the second frequency comb after an interaction with the sample. A computing device receives output of the detector device and calculates spectroscopic properties of the sample.

摘要： The present invention concerns a geosynthetic element for a geotechnical engineering application. The geosynthetic element comprises: bacteria carriers for carrying bacteria arranged to be propagated from the geosynthetic element to a surrounding geomaterial; and a flow network comprising openings on its surface to allow a reactant to escape the flow network to the surrounding geomaterial along the flow network to produce solid calcium carbonate when in contact with the bacteria. The reactant flow network further comprises a set of inlets for feeding the reactant into the flow network, and a set of outlets for recovering at least a part of the reactant from the reactant flow network.

摘要： The present invention concerns a method of displaying an image on a see-through display. The method comprises: obtaining (101) a first electro-magnetic radiation matrix of an object, the first matrix comprising first matrix elements representing radiation intensity values of corresponding locations of the object; dividing (103) the first matrix into a second matrix representing a first subset of the radiation intensity values of the matrix elements, and a third, different matrix representing a second, different subset of the radiation intensity values of the matrix elements; generating (105) a first histogram for the second matrix; equalising (107) the first histogram to obtain an equalised second histogram; generating (109) a first grayscale image representing the first subset of the radiation intensity values from the second matrix and the equalised second histogram; colouring (111) the first grayscale image with a first colourmap to obtain a first colour image; generating (113) a second grayscale image representing the second subset of the radiation intensity values image by mapping substantially linearly the second subset of the radiation intensity values to a given number of encoded radiation intensity values; colouring (115) the second grayscale image with a second colourmap, which is different from the first colourmap, to obtain a second colour image; combining (117) the first colour image and the second colour image to obtain a combined colour image; and displaying (123) the combined colour image on the see-through display.

摘要： The invention relates to a contact lens for use in the treatment of ocular inflammatory pathologies. The contact lens comprises a soft porous material coupled, in certain embodiments, with detoxifying agents. Said material and/or agents contact and neutralize inflammatory mediators present in the tear fluid of ocular pathologies patients. The nature and architecture of the soft porous material allows a greater contact area between the material itself and/or detoxifying agents with inflammatory mediators, in view of the reversible compression of the soft material that allows greater lachrymal fluid turnover and fluid exchange within the contact lens upon e.g. blinking.

摘要： A biosensor includes a source element; a drain element; a semiconductor channel element between the source element and the drain element for forming an electrically conductive channel with adjustable conductivity between the source and drain elements; a first gate element configured to be electrically biased to set a given operational regime of the sensor with given electrical conductivity of the channel; and a second gate element, physically separate from the first gate element, configured to contact a solution comprising analytes allowed to interact with a gate contact surface of the second gate element to generate a surface potential change dependent on the concentration of the analytes in the solution. The channel element is substantially fully depleted allowing the first and second gate elements to be electrostatically coupled such that the surface potential change at the second gate element is configured to modify the electrical conductivity of the channel.
