Gap-filling a spatially explicit plant trait database: comparing imputation methods and different levels of environmental information [PDF]
Biogeosciences, 2018 The ubiquity of missing data in plant trait databases may hinder trait-based analyses of ecological patterns and processes. Spatially explicit datasets with information on intraspecific trait variability are rare but offer great promise in improving ...

Intrinsic Random Function Kriging on the Sphere
Journal of Statistical Theory and PracticeAbstract Intrinsic random functions (IRFs) can be used to model spatial processes on the sphere. To perform kriging using IRFs, one needs the knowledge of the IRF order (i.e., the degree of non-homogeneity) and its associate generalized covariance function, which are challenging in Euclidean spaces and hinder its practice.

Improving Estimations of Spatial Distribution of Soil Respiration Using the Bayesian Maximum Entropy Algorithm and Soil Temperature as Auxiliary Data. [PDF]
PLoS ONE, 2016 Soil respiration inherently shows strong spatial variability. It is difficult to obtain an accurate characterization of soil respiration with an insufficient number of monitoring points. However, it is expensive and cumbersome to deploy many sensors.

Functional Generative Design: An Evolutionary Approach to 3D-Printing
, 2018 Consumer-grade printers are widely available, but their ability to print complex objects is limited. Therefore, new designs need to be discovered that serve the same function, but are printable.
