The present invention provides cell-laden hydrogels and hydrogel assemblies thereof for use in tissue engineering. A method of manufacturing a display in which the method of manufacturing a thin film transistor is used is also provided. Each of the quantity of return signals received is routed in one to one correspondence to the sub-band filters, each signal being received at a corresponding sub-band filter. With respect to the longitudinal direction, two adjacent regular dodecagon fuel rod arrangements are arranged so that the opposing two sides of the regular dodecagons are parallel to each other with the distance of nA, wherein n is a nonnegative integer, apart from each other. Each configurable IC is adapted to use a common Local Oscillator signal, a common clock signal, and a common timing signal for determining at least the start of the common sampling window.
