Embodiments are provided for associating a virtual column with a target physical table. Based on a result of detection provided by a document detecting section for detecting the presence or absence of a document, it is determined whether or not an e-mail is transmitted with use of an attachment file by an e-mail transmitting section. In a typical embodiment, a composition of the invention includes an agent associated with a neuronal tracer which associates with a neuron to facilitate uptake of the agent by the neuron cell body. In other embodiments, the method includes providing a prize to the player based on the outcome. Substantially identical groupings of the truncated cells are then segregated respectively into differing ones of a plurality of buckets, whereby each of these buckets comprise a single set of identical groupings of truncated cells.
