The invention relates to a cell sheet construct for neurovascular reconstruction. The dirty indicators are stored in groups with each group having associated therewith a validity indicator computed from the dirty indicator values of the group. An adaptive strategy is used in which after each stage of interference cancellation, impairment covariance is parametrically updated and combining weights of the receiver are adapted to reflect the updated impairment covariance. 1-30% calcium oxide, a metal sulfate whose solubility is 1 g or more in 100 g of water at 5 degrees C and at least one or more kind of phosphoric acid, the dried coating film having a thickness between 1 m and 200 m. The modulator provides information of bit of two-dimensional data to each corresponding pixel by application or non-application of a voltage, and modulates the polarization of the beam incident on each pixel. Related apparatus and methods are also included.
