Minimum-Density Identifying Codes in Square Grids [PDF]
An identifying code in a graph $G$ is a subset of vertices with the property that for each vertex $v \in V(G)$, the collection of elements of $C$ at distance at most $1$ from $v$ is non-empty and distinct from the collection of any other vertex. We consider the minimum density $d^*({\cal S}_k)$ of an identifying code in the square grid ${\cal S}_k$ of ...

Cooperative LVRT control for protecting PMSG-based WTGs using battery energy storage system
Low-voltage ride-through (LVRT) capability is crucial for wind power plants that are grid-connected. A grid code requires wind farms to remain on-grid and inject a specific reactive current when a grid fault occurs.

The GridCAT: A Toolbox for Automated Analysis of Human Grid Cell Codes in fMRI
Human functional magnetic resonance imaging (fMRI) studies examining the putative firing of grid cells (i.e., the grid code) suggest that this cellular mechanism supports not only spatial navigation, but also more abstract cognitive processes.

To maintain power system stability and supply quality when integrating doubly fed induction generator (DFIG)-based wind energy conversion systems (DFIG-WECSs), regulators regularly update grid codes specifying low voltage ride-through (LVRT) requirements.

Hippocampal remapping is constrained by sparseness rather than capacity. [PDF]
Grid cells in the medial entorhinal cortex encode space with firing fields that are arranged on the nodes of spatial hexagonal lattices. Potential candidates to read out the space information of this grid code and to combine it with other sensory cues ...

Finding Codes on Infinite Grids Automatically
We apply automata theory and Karp’s minimum mean weight cycle algorithm to minimum density problems in coding theory. Using this method, we find the new upper bound 53/126 ≈ 0.4206 for the minimum density of an identifying code on the infinite hexagonal grid, down from the previous record of 3/7 ≈ 0.4286.

End-to-End QoS Support for a Medical Grid Service Infrastructure [PDF]
Quality of Service support is an important prerequisite for the adoption of Grid technologies for medical applications. The GEMSS Grid infrastructure addressed this issue by offering end-to-end QoS in the form of explicit timeliness guarantees for ...

Mutual Remodeling and Conformation Grid: A Mediator Code? [PDF]
How does a common RNA polymerase II apparatus generate a complex pattern of transcripts in response to many gene-specific transcription factors and in accordance with cell's state? In this issue of Structure, Cai et al. reveal that the process involves coordinated conformational changes in Pol II and Mediator.
