The grid code for ordered experience
Nature Reviews Neuroscience, 2021Entorhinal cortical grid cells fire in a periodic pattern that tiles space, which is suggestive of a spatial coordinate system. However, irregularities in the grid pattern as well as responses of grid cells in contexts other than spatial navigation have presented a challenge to existing models of entorhinal function.

On Identifying Codes in the Triangular and Square Grids
SIAM Journal on Computing, 2004Summary: It is shown that in the infinite square grid the density of every \((r, \leq 2)\)-identifying code is at least 1/8 and that there exists a sequence \(C_r\) of \((r, \leq 2)\)-identifying codes such that the density of \(C_{r}\) tends to 1/8 when \(r \rightarrow \infty\).

X-ray tomography by grid coding
Applied Optics, 1980Three-dimensional objects are coded using a crossbar grid by an array of simultaneously flashed x-ray tubes. This is a new version of flashing tomosynthesis. The technique is experimentally tested using radiographs of a heart phantom.

A Grid Version of the Fusion Code FAFNER
2010 18th Euromicro Conference on Parallel, Distributed and Network-based Processing, 2010FAFNER is code developed by Lister which simulates by Monte Carlo methods the Neutral Beam Injection (NBI) technology, one of the most extended heating methods for fusion devices. To the date, FAFNER has been usually run at CIEMAT adapted to the TJ-II helical axis stellarator on shared memory Cray architecture machines.

ACM Transactions on Storage, 2009
As storage systems grow in size and complexity, they are increasingly confronted with concurrent disk failures together with multiple unrecoverable sector errors. To ensure high data reliability and availability, erasure codes with high fault tolerance are required.

The Cactus Code: a problem solving environment for the grid
Proceedings the Ninth International Symposium on High-Performance Distributed Computing, 2002Cactus is an open source problem solving environment designed for scientists and engineers. Its modular structure facilitates parallel computation across different architectures and collaborative code development between different groups. The Cactus Code originated in the academic research community, where it has been developed and used over many years

Bounds for Codes Identifying Vertices in the Hexagonal Grid
SIAM Journal on Discrete Mathematics, 2000In an undirected graph \(G=(V,E)\), a subset \(C\) of \(V\) is called an identifying code of the sets \(B_1(v)\cap C\) consisting of all elements of \(C\) within distance one from the vertex \(v\) if these sets are nonempty and different. The authors take as \(G\) the infinite hexagonal grid graph and show that the density of any identifying code is at

Grid Codes: Goals and Challenges
2014Electric power has always been one of the driving forces for progress in human life. This has popularized electric energy as the most utilized form of energy. However, dispersed locations of energy resources and continuously increasing demand of electricity have led to a large electric power transmission network across the landscape.
