A New Algorithm for Large-Scale Geographically Weighted Regression with K-Nearest Neighbors

ISPRS International Journal of Geo-Information, 2023
Geographically weighted regression (GWR) is a classical method for estimating nonstationary relationships. Notwithstanding the great potential of the model for processing geographic data, its large-scale application still faces the challenge of high ...

Spatiotemporal Modeling and Composite Indices for Pandemic Preparedness: A Novel Geospatial‐Temporal Approach

Geographical Analysis, Volume 58, Issue 3, July 2026.
ABSTRACT This study proposes a geographically and temporally weighted random forest (GTWRF) model for explanatory spatiotemporal analysis of COVID‐19 outcomes. GTWRF extends the conventional geographically weighted random forest by incorporating spatial and temporal dependencies through an adaptive Gaussian weighting scheme.

Gray-White Matter Ratio at the Level of the Basal Ganglia as a Predictor of Neurologic Outcomes in Cardiac Arrest Survivors: A Literature Review

Frontiers in Medicine, 2022
Loss of gray-white matter discrimination is the primary early imaging finding within of cranial computed tomography in cardiac arrest survivors, and this has been also regarded as a novel predictor for evaluating neurologic outcome.

Constructing Improved Overlap Fermions in QCD [PDF]

, 2000
We describe an explicit construction of approximate Ginsparg-Wilson fermions for QCD. We use ingredients of perfect action origin, and further elements. The spectrum of the lattice Dirac operator reveals the quality of the approximation. We focus on beta

The Social Equity of Spatial Compactness Varies by Context: Evidence From Belfast, Glasgow and Liverpool

The Geographical Journal, Volume 192, Issue 2, June 2026.
Short Abstract This paper examines the relationship between urban compactness and social equity across three UK cities. Using a multidimensional compactness framework and multiscale geographically weighted regression (MGWR), it analyses how demographic characteristics relate to spatial compactness at a fine scale.

17-09 Assessing the Impact of Air Pollution on Public Health Along Transit Routes [PDF]

, 2019
Transportation sources account for a large proportion of the pollutants found in most urban areas. Also, transportation activity and intensity appear likely to contribute to the risk of respiratory disease occurrence.

Convergence Rate and Locality of Improved Overlap Fermions [PDF]

, 2002
We construct new Ginsparg-Wilson fermions for QCD by inserting an approximately chiral Dirac operator - which involves ingredients of a perfect action - into the overlap formula.

Innovation Ecosystems in Catalonia: Exploring Location Patterns of High‐Tech Firms

Growth and Change, Volume 57, Issue 2, June 2026.
ABSTRACT This paper analyses high‐tech firms' location determinants in Catalonia, Spain, using 2010–2019 firm data, and spatial models to assess spillover and industry‐specific factor effects. Results show that high‐tech firms, especially in services, are clustered in busy, wealthy cities with strong innovation hubs, while non‐high‐tech firms prefer ...
