A method for exchanging data in messages between at least two stations connected via a bus system. The organic electronic material is characterized by comprising charge transporting compounds and ionic compounds, and in that at least one of the ionic compounds is any one kind of compounds represented by general formulas -. The linear groove having a longitudinal axis that passes through a midpoint of a straight line connecting a rotation center of a first paper roll bearing-supported in the first notches and a rotation center of a second paper roll bearing-supported in the second notches. Then, a new set of states of the second trace is computed and the result is represented as a logical formula. A logic gate array comprises a plurality of vertical ultrathin transistors coupled together. The compositions may include pharmaceutical compositions that are used as \u03b3\u03b4 T cell stimulating vaccines or immunogenic compositions for preventing or treating microbial infections and hyperplasias such as cancer.
