A coarse evaluation lock on data is provided to ensure only one evaluation is run on selected data until completed. A tissue patch includes a substrate, a tissue implant attached to the substrate, and a protective liner covering at least a portion of the tissue implant. In other embodiments of the sofa lover’s sofa, a sofa or the like can have a lower front panel that is rotatable to a position overlying a seat cushion so as to act as an armrest for a person sitting crosswise on the sofa. Each gene or gene fragment has been registered or mapped to a specific location in the genome of the organism. A table top is removably coupled to the cross-bar covers.
