The present invention relates to a surface discovery system comprising chemical compositions and high-throughput combinatorial synthesis methods for generating large numbers of diverse surface coatings on solid substrates. The facility receives a plurality of addresses of hosts in the network, and accesses a binary tree. Therefore, the wireless cursor-controlling device can be used for controlling the computer cursor as well as a digital recording device. A handle assembly is slideably engaged with the elongated member in the hand guard and the handle assembly is moveable toward the receiver to define a charging motion. The invention further relates to a method for growing an at least double layered cell aggregate into an artificial blastocyst, and into a further-developed blastoid, a fetus or a live animal.
