In vitro whole cell patch-clamp recordings of stellate cells in layer II of medial entorhinal cortex show a subthreshold membrane potential resonance in response to a sinusoidal current injection of varying frequency. Physiological recordings from awake behaving animals show that neurons in layer II medial entorhinal cortex, termed "grid cells," fire in a spatially selective manner such that ea...

There area lot of mobile computer devices with a variety of applications and users Tend to use them more. Due to the limitations of mobile devices, running most of the procedures are impossible. To resolve this problem, mobile devices can be connected to the grid, to use the facilities of grid. On the other hand the communication mechanisms are different for each device and they cannot be c...

Given a knot presented in a grid diagram, we construct a CW complex which has one cell for each generator of the grid chain complex, and whose homology is the grid homology. This space is welldefined, and its stable homotopy type is a knot invariant. Thus to each knot, we can associate an invariant spectrum, whose F2 homology is the knot Floer homology over F2. 1991 Mathematics Subject Classifi...

Pathfinding on a map is a fundamental problem in many applications, including robotics and computer games. Typically a grid is superimposed over the map where each cell in the grid forms a unique state. A state-space-based search algorithm, such as A* or IDA*, is then used for finding the optimal (shortest) path. In this paper we analyze the search behavior of both A* and IDA* using different g...

The goal of this paper is to estimate in a theoretical way the reduction of the number of cells of, and the overall number of neighbouring cells in, a grid when some cells in a uniform grid are replaced by a larger cell in an overlaying non-uniform grid. We assume that the grids are represented by a 2 k-tree and the replacement of cells preserves the representation.

the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...

ions ( other country GW  ) were downscaled to grid level ( other cell GW  ) based on proportion of each cell water use in other sector ( MAgPIE Other WU  ) to country total water use in other sectors (( MAgPIE Other WU  )Country) as obtained from the MAgPIE model results. In the final step, downscaled grid level groundwater abstractions for agriculture and other sectors were addded to get t...

While grid cells in the medial entorhinal cortex (MEC) of rodents have multiple, regularly arranged firing fields, place cells in the cornu ammonis (CA) regions of the hippocampus mostly have single spatial firing fields. Since there are extensive projections from MEC to the CA regions, many models have suggested that a feedforward network can transform grid cell firing into robust place cell f...

—We examined the structural and spatial distribution of woody biomass in relationship to disturbance in an Indiana old-growth deciduous forest over a 66-yr period. Analysis was done on the core 7.92 ha of a 20.6-ha forest in which every tree 10 cm dbh and over has been tagged and mapped since 1926. Five years are compared—1926, 1976, 1981, 1986 and 1992. Dry weight of living biomass for the 7.9...
