DOI: 10.1007/s10457-018-0334-3
Abstract: Although there is greater awareness of spatial variability of factors affecting plant growth, regression methods with residuals independently and identically distributed, are still used. Thus, we compared spatial and non-spatial regression models in evaluating the… read more here.

DOI: 10.1016/j.geoderma.2016.10.010
Abstract: Abstract Visible and near-infrared (VNIR) reflectance spectroscopy is a rapid, non-destructive, and cost-effective method for predicting soil properties. Partial least squares regression (PLSR) is a common method used to predict soil properties based on VNIR… read more here.

DOI: 10.1080/00343404.2017.1314457
Abstract: ABSTRACT Spatial agglomeration is well theorized within regional studies and economic geography, with firm- and industry-level advantages generally attributable to the strategic benefits derived from spatial proximity. Increasingly, alternative proximity types have been explored to… read more here.

DOI: 10.1109/lwc.2022.3146026
Abstract: This letter provides a novel hierarchical-block channel estimation scheme for massive multiple-input multiple-output (MIMO) systems based on Bayesian learning frameworks. Specifically, considering the spatial non-stationarity of massive MIMO channels introduced by a large-scale antenna array,… read more here.

DOI: 10.1364/ol.491880
Abstract: We introduce a class of structured light beams, named multi-focus beams, which exhibit self-focusing at multiple propagation distances. We show that the proposed beams not only have the ability to produce multiple longitudinal focal spots,… read more here.

DOI: 10.3390/su10072242
Abstract: Understanding the spatial distribution of land surface temperature (LST) and its impact factors is crucial for mitigating urban heat island effect. However, few studies have quantitatively investigated the spatial non-stationarity and spatial scale effects of… read more here.
