Toroidal topology of population activity in grid cells
Nature, 2021 The medial entorhinal cortex is part of a neural system for mapping the position of an individual within a physical environment1. Grid cells, a key component of this system, fire in a characteristic hexagonal pattern of locations2, and are organized in ...

Grid-Forming Converters: Control Approaches, Grid-Synchronization, and Future Trends—A Review
IEEE Open Journal of Industry Applications, 2021 In the last decade, the concept of grid-forming (GFM) converters has been introduced for microgrids and islanded power systems. Recently, the concept has been proposed for use in wider interconnected transmission networks, and several control structures ...

Distributed Computing in a Pandemic
Advances in Distributed Computing and Artificial Intelligence Journal, 2022 The current COVID-19 global pandemic caused by the SARS-CoV-2 betacoronavirus has resulted in over a million deaths and is having a grave socio-economic impact, hence there is an urgency to find solutions to key research challenges. Much of this COVID-19

Common-Ground Photovoltaic Inverters for Leakage Current Mitigation: Comparative Review
Applied Sciences, 2021 In photovoltaic systems, parasitic capacitance is often formed between PV panels and the ground. Because of the switching nature of PV converters, a high-frequency voltage is usually generated over these parasitic capacitances; this, in turn, can result ...

Efficient embeddings of grids into grids
Discrete Applied Mathematics, 2001 An embedding of a graph \(G\) into a graph \(H\) is a pair of two mappings: an injection \(\phi:V_G\mapsto V_H\) and a routing scheme that maps \(E_G\) into the set of paths in \(H\). The authors consider two embedding parameters: dilation, defined as the length of a longest path in the image of the routing scheme, and the edge-congestion, defined as ...

Experimental Study of Explosion Mitigation by Deployed Metal Combined with Water Curtain
Applied Sciences, 2021 In this paper, protective barriers made of perforated plates with or without a water cover were investigated. In urban areas, such barriers could be envisaged for the protection of facades.
