  • Publication number: 20190333212
    Abstract: Disclosed is a technique for estimating a biomechanical structure of one or more derived human cardiomyocytes (CMs) on basis of at least one image that represents derived human CMs, the method including detecting respective image positions of predefined elements of the derived human CMs, including detecting first positions that indicate respective adhesion points of a cell outline of the derived human CMs where they attach to their substrate and detecting second positions that indicate respective positions of nuclei of the derived human CMs; dividing the image representation of the derived human CMs into a plurality of areas that represent respective sarcomeres of the derived human CMs; and carrying out a further analysis of the derived human CMs on basis of division of their image representation into the plurality of areas.

  • Patent number: 9582894
    Abstract: Method for analyzing the beating of a derived human cardiomyocyte (CM) includes obtaining the derived human CM, capturing a sequence of images depicting the derived human CM over an analysis period, and determining at least one signal descriptive of the beating of the derived human CM during the analysis period on basis of the sequence of captured images. Apparatuses, and a computer program for analyzing the beating of a derived human CM are configured to obtain: the sequence of images depicting the derived human CM over an analysis period, information indicative of the region of the images depicting the derived human CM, information indicative of two or more sub-regions within the region, and determine two or more signals characterizing the displacement within the region of images depicting the derived human cardiomyocyte, each signal characterizing the extent of displacement within a respective sub-region of the region as a function of time.

  • Publication number: 20140024958
    Abstract: Various embodiments relate to a method, apparatus, system, and a computer program product for suppressing an oscillatory signal Sosc. In the method a composite signal S comprising said Sosc and a modulating signal Smod are provided and the S is high pass filtered to produce estimates of the Sosc and the Smod, wherein the estimate of the Sosc comprises first oscillations during a first state of the modulating signal and second oscillations during a second state of the modulating signal. A first bin associated with said first state and a second bin associated with said second state are defined and assigned for said first oscillation and the second bin for said second oscillation according to a state defined from the estimate of the Smod. A first average waveform for said first oscillations and a second average waveform for said second oscillations are formed and used to suppress the Sosc signal from the composite signal S.

  • Patent number: 8492125
    Abstract: The present invention relates to a method for dissolving cellulose. The method comprises—introducing cellulosic raw material,—treating the cellulosic raw material in an enzymatic treatment process,—mixing the cellulosic raw material after the enzymatic treatment in an aqueous solution in order to obtain an aqueous intermediate product containing the cellulosic raw material of at least 3.5 wt.-%, alkali metal hydroxide between 3.5 wt.-% and 7 wt.-% and zinc salt,—freezing the intermediate product to a solid state, and—melting the frozen intermediate product. The present invention also relates to a cellulosic product obtained from a solution comprising dissolved cellulose.
