Space‐Time Smoothness and Parsimony in Covariance Functions

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper challenges the trade off between computational efficiency and statistical accuracy within the framework of Gaussian space‐time processes. Under such a framework, the space‐time dependence is completely specified through the space‐time covariance function.

Folate‐Associated DNA Methylation and Chemotherapy‐Induced Toxicities in Patients With Colorectal Cancer

open access: yesMolecular Nutrition &Food Research, EarlyView.
Over half of patients with colorectal cancer experience severe chemotherapy‐induced side effects. The B‐vitamin folate may play a role in these side effects, potentially by altering DNA methylation, a mechanism of gene regulation. Our comprehensive literature search identified studies investigating DNA methylation associated with folate status/intake ...

Exact analytical solutions of the Bloch equation for the hyperbolic‐secant and chirp pulses

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To improve the accuracy and generality of analytical solutions of the Bloch equation for the hyperbolic‐secant (HS1) and chirp pulses in order to facilitate application to truncated and composite pulses and use in quantitative methods.

The latitudinal gradient in European ant dark diversity: patterns and potential mechanisms

open access: yesOikos, EarlyView.
Observed richness has long been the basis for studies of species distribution patterns and community ecology, but dark diversity (i.e. the group of species in the regional pool that can live under the specific local environmental conditions but which are not part of the local species richness) has recently gained prominence for providing complementary ...

Characterizing season‐long floral trajectories in cotton with low‐altitude remote sensing and deep learning

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plant breeding is a critical tool for increasing the productivity, climate resilience, and sustainability of agriculture, but current phenotyping methods are a bottleneck due to the amount of human labor involved. Here, we demonstrate high‐throughput phenotyping with an unmanned aerial vehicle (UAV) to analyze the season‐long flowering pattern in ...
