This study investigated whether a stacked bar’s vertical arrangement or single-object properties underlie its accuracy for proportion judgments. We hypothesized that observers would be less accurate when stacked bars were separated than when they formed a single object, according to the object-based theory of attention (Duncan, 1984). Thirty participants judged proportions with three different ...

As the size of a transistor continuously scales down, single electron effects become important [1 – 3]. Previously, we have studied charge transport in single-electron quantum dot transistors which have a channel consisting of a silicon dot separated from the source and the drain by two constrictions [4], and in single-electron MOS memories that have a polysilicon dot floating gate stacked on a...

In addition to orthogonal and quasi-orthogonal space-time block codes (OSTBC, QSTBC), cyclic delay diversity (CDD) is a transmit diversity scheme that achieves full diversity gain of NnR, with N transmit antennas and nR receive antennas. The performance in terms of spatial multiplexing gain is quite limited, since all degrees of freedom are used to obtain diversity. Thus the gap between the div...

In the title molecular salt, C(7)H(20)N(2) (2+)·2NO(3) (-), the crystal structure exhibits an unusual back-to-back paired double-stacked packing arrangement culminating in an overall double zigzag pattern of the dications. The nitrate anions form a ring around one pair of double-stacked dications. An intricate three-dimensional N-H⋯O and N-H⋯(O,O) hydrogen-bonding network exists in the crystal ...

A modification of stacked spiral inductors increases the self-resonance frequency by 100% with no additional processing steps, yielding values of 5 to 266 nH and self-resonance frequencies of 11.2 to 0.5 GHz. Closed-form expressions predicting the self-resonance frequency with less than 5% error have also been developed. Stacked transformers are also introduced that achieve voltage gains of 1.8...

3-D integration technologies are discussed focusing on key technologies such as through-silicon via (TSV), metal microbump, wafer thinning, wafer bonding, wafer alignment and so forth. It is shown that 3-D LSI is suitable for low power operation since the interconnection length can be significantly reduced and the parallel processing can be effectively introduced. In addition, a future new 3-D ...

In the title compound, C(11)H(15)NO(3), the mean planes of the carboxamide and isopropyl groups are inclined at 109.9 (1) and 128.7 (2)°, respectively, to the mean plane of the phen-oxy group. In the crystal structure, mol-ecules are stacked along the b axis, without any π-π inter-actions. The stacked columns are linked together by inter-molecular N-H⋯O hydrogen bonds, with an N⋯O distance of 2...

BACKGROUND AND AIM: The aim of the present study was to evaluate the effect of different needle-insertion depths on the accuracy of the Root ZX II and Root ZX mini apex locators in the presence of various irrigants. METHODS: Ninety extracted single-canal human teeth were used in nine experimental groups. The coronal one-third of the canals was preflared, and the length to the major foramen was ...
