Remarks on the one-point density of Hele-Shaw $\beta$-ensembles

In this note we prove equicontinuity for the family of one-point densities with respect to a two-dimensional Coulomb gas at an inverse temperature $\beta\ge 1/2$ confined by an external potential of Hele-Shaw (or quasi-harmonic) type. As a consequenc

There is still no reliable solution for obtaining Digital Terrain Models (DTM) under the canopy in areas with difficult access on foot. The difficulty lies in the configuration of the environment. This configuration does not allow access on foot to a

Deep Learning Improves Point Density in PS-InSAR Data Toward Finer-Scale Land Surface Displacement Detection

Autor: Anastasiia Safonova, Masahiro Ryo

Publikováno v: IEEE Access, Vol 12, Pp 132754-132762 (2024)

The permanent scatterer interferometric aperture radar (PS-InSAR) technique is used to measure and monitor displacements of the Earth’s surface over time. While the approach is promising for large-scale deformation, the density of the received PS p

A comparison of raster-based point density calculations to vector-based counterparts as applied to the study of food availability

Autor: Timothy Mulrooney, Samuel Akinnusi, Christopher McGinn, Chima Okoli, Tony Esimaje

Publikováno v: Agriculture & Food Security, Vol 13, Iss 1, Pp 1-15 (2024)

Abstract Background Proximity to food sources is one of the quantifiable factors measurable across space impacting diet-related health outcomes. Contemporary research has coined the terms ‘food desert’ and ‘food swamp’, sometimes combined wit
