Techniques for performing a process during a real time collaboration by multiple users or clients on a spreadsheet file are disclosed herein which may permit calculations to be performed locally by at least one of the clients. WNT-derived peptide of the present invention possesses identical or similar activities to natural-occurring WNT protein, and has much higher stability and skin penetration potency than natural-occurring WNT protein. A circuit component recognizing the arbitrarily mounted cartridge and informing an external apparatus of specifications of the recognized cartridge is provided at the main logic board. Accordingly, in some embodiments, there are two design challenges: the choice of the network abstraction, and the technology needed to compile the logical \u201cabstract\u201d controls into low-level configurations. This second software program may be executed on the computer so that a control function of a stored-program controller can be taken over by a computer by way of a particular process. The invention also relates to a structure in which no buckets are used.
