Their work revives long-standing mathematical curiosities but does so through a fresh window – additive combinatorics.

Objective To analyse the spatial clustering of COVID-19 case fatality risks in the districts of Bangladesh and to explore the association of sociodemographic indicators with these risks. Study design ...

On the other hand, trying to portray a condition in which the spatial distribution pattern is random can be especially complicated when dealing with linear features, as these, unlike points, have ...

Insufficient sample size will lead to unstable results. With the increase of the number of samples to more than 120, the V value and P value curves will eventually stabilize. That is, stable spatial ...

The unique characteristics of SVs in China have attracted the attention of relevant scholars. Existing studies mainly focused on the spatial pattern of SVs, the spatial aggregation and diffusion of ...

Spatial patterns in distribution of galaxies Date: March 14, 2023 Source: Princeton University Summary: In an unlikely pairing, a chemist and an astrophysicist applied the tools of statistical ...

Abstract. Objectives: to assess factors associated with early weaning and the pattern of spatial distribution of breastfeeding in the ascription territory of a Basic Health Unit (BHU). Methods: ...

Where Wij (d) is the spatial weight vector that defines values for location j (within the distance of d) from neighboring location i.W * i is the sum of the weights Wij, S * 1i is the square sum of ...

A spatial colocation pattern represents a subset of spatial features with instances that are prevalently located together in a geographic space. Although many algorithms for mining spatial colocation ...
