Abstract: In a method for a cooktop, in particular for producing and/or operating the cooktop, which has at least one variable cooking surface, the cooking surface is partitioned in an operating mode along a partitioning direction into a plurality of heating zones to which at least one heating parameter is assigned in each case in a location-dependent manner in order to heat a cooking utensil that is deposited on the heating zone. In order to ensure flexible production and/or flexible operation of the cooktop, during partitioning of the cooking surface into the heating zones in at least one peripheral region of the cooking surface, at least one cooking utensil characteristic is taken into account.

Abstract: A method and system for detecting, manipulating and isolating circulating tumor cells found in organic fluids comprising a simplified laser assisted transfer process. A liquid specimen of the organic fluid containing an enriched population of tumor cells and a population of non-tumor cells is spread onto a donor substrate with an interlayer comprising a semi-transparent polymeric adhesive tape. A fluorescent staining of at least one of the cell populations present in the liquid specimen is required to identify-using optical and fluorescence microscopy, the location of the cells to be manipulated and/or isolated. The laser beam energy is absorbed by the polymeric adhesive tape giving place to the formation of a blister that mechanically interacts with the liquid specimen and such interaction can induce the expulsion of a portion of the liquid specimen comprising the selected tumor cells or non-tumor cells, which can be a single cell or a cell cluster, towards the receiving substrate.
