A new cultivar of Ulmus pumila, \u2018Meirenyu\u2019, characterized by its foliage that is bright yellow in color with the yellow color retained throughout the growing season on leaves with good sun exposure and by its young branches that are orange-red in color. In various embodiments, the apparatus includes a source material, a buffer material, a select gate drain, and a memory stack arranged between the source material and the SGD. Based on the difference between the mirrored differential current and the mirrored common mode current, the circuit pulls up or pulls down these currents to balance the corresponding difference between the differential input and the common mode input. The second gage section defines a second cross-sectional area that is defined by a second plane that extends through the second gage section and is perpendicular to the central, longitudinal axis and wherein the first cross-sectional area is different in size than the second cross-sectional area. The update of the air fuel ratio learning value is inhibited when the air fuel ratio detection device shifts to a rich or lean side. Each said second substrate can have formed thereon a magnetic circuit and each magnetic circuit can have a plurality of logic elements, a data writing element and a data reading element.
