To test whether inhibition, like excitation, is driven by rectified receptive field subunits and to measure their spatial extent, we sinusoidally modulated square-wave gratings with different bar widths in an annular region overlaying the receptive field surround.
Instead, a digital planimeter was used to measure the spatial extent and number of slope failures in each of eight vegetation types (exotic forest, indigenous forest, secondary indigenous regrowth, exotic cutover 1992/93, cutover 1993/94, cutover 1994/95, pasture (hill country) and pasture (floodplain) assessed from the forest compartment maps (Table 2).
The density profiles (Supplementary Fig. S1) were used to measure the spatial extent of intrinsic labeling in the large injections that are required for optimal labeling of the full complements of inputs and their FLN values.
Mean square displacement (MSD) plots, measuring the spatial extent of the random motion, and fitting to an anomalous diffusion curve suggested a restricted nucleosome movement.
In statistical mechanics, it demonstrates the measure of the spatial extent of random motion measuring the portion of the system "explored" by the random walker, and is defined as mathrm{Mean} mathrm{square} mathrm{displacement} = <{left x-{x}_0right)}^2 > =kern0.5em frac{1}{T}{displaystyle {sum}_{t=1}^T{left(x(t)-{x}_0right)}^2} (3).
A future study where analysis of the individual relationship between BOLD response and pain measurements may be desirable, using a technique such as flatmapping to measure the definitive spatial extent of activation maps.
It is important to note that occupancy is a combined measure of both spatial extent and density.
Parameters are estimated based on this strategy and include measures of the spatial extent of flow, the spatial integral of flow, and the time required for 80% replenishment.
The purpose of this paper is to empirically measure the strength and spatial extent of the relationships among the amount of funds raised by proximate biotechnology firms.
To measure the degree and spatial extent of pain nerve block both quantitatively and precisely in post-operative thoracic and abdominal adult surgical patients who have been given an epidural for their anesthetic administration.
Allik and Tuulmets, for example, presented a quantitative model of numerosity estimation of dot collections that is entirely based on a combined measure of the collections' spatial extent and density [14].
