Spatial configuration of mRNA 5′-terminus
Nature, 1977Nuclear magnetic resonance investigation has revealed that the 5'-terminus m7G5'ppp5'Am of mRNA displays a spatial configuration in which the bases form stacked arrays. Details of the conformation as derived from coupling constants, shift trends and ring current considerations are discussed.

Spatial configurations for visual hyperacuity
Vision Research, 1977Abstract The threshold for discrimination of relative position of two features in the fovea is lowest—a few sec of arc—when the two features are separated by 2–5′ arc. and is not significantly changed when the features are reduced to dots. Discrimination for lateral displacement, e.g. vernier acuity, is as good as for spatial intervals, e.g.

Qualitative Spatial Configuration Search
Spatial Cognition & Computation, 2016Current Geographic Information Systems (gis) lack, to a large extent, support for spatial searches in which a user wants to find a configuration of objects described in qualitative terms. At the database level, these searches can be supported by providing new spatial operators that can capture the semantics of the qualitative spatial relations used in ...

Minimal Spatial Accelerometer Configurations
Journal of Dynamic Systems, Measurement, and Control, 2013It is well established that it is necessary to use a minimum of six accelerometers to determine the general motion of a rigid body. Using this minimum number of accelerometers generally requires that a nonlinear differential equation be solved for the angular velocity and that the estimate of angular velocity that is obtained from the solution of this ...

Spatial configurations: Erikson reexamined
Sex Roles, 1985In a 1951 study, Erik Erikson reported differences in preadolescents' play constructions. He claimed that his findings reflected differences between males and females in their experience and perception of space. The present study replicated but also expanded the original design.

Spatial Configuration and Proximal Cues
Learning and Motivation, 1998Abstract Rats were trained in a radial arm maze task to a criterion of at least seven correct choices in the first eight for three consecutive days. There were minimal extramaze cues in the experimental environment, and intramaze cues, in the form of textured inserts on the maze arms, were provided.
