Instead, teaching that includes both 2D and 3D models is likely the most advantageous, as it promotes generalization of knowledge by forcing students to practice moving fluidly between dimensions. To assess the influence of stereopsis in more complex learning environments, carefully controlled ...

in two dimensions [2–5]; in three dimensions ζ is approximately 3/5 whereas in four and higher dimensions the value of ζ is equal to 1/2 [2] and the universality class of self-avoiding random walks merges with that of ordinary random walks. However, on irregular lattices, such as ...
planar, that is, whether it can be drawn in two dimensions without any links crossing (wires touching). The(computational) complexityof an algorithm is a measure of the amount of computing resources (time and space) that a particular algorithm consumes when it runs. Computer scientists use ...
Finally, by auditing both survey respondents and non-respondents, we are able to assess the degree to which there is differential selection along observable dimensions in our sample. Audit activities In order to validate our survey responses and check for balance across respondents and non-...
