Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Solubility Challenges and Strategies for Organic Sodium‐Ion Batteries: Status and Perspectives

open access: yesSmall, EarlyView.
Organic sodium‐ion batteries (OSIBs) have garnered interest due to their low cost, abundant resources, and sustainability. However, the solubility of organic materials in aprotic electrolytes results in electrode deterioration, active material loss, and poor cycling stability.

The S-Transform on Hardy Spaces and Its Duals

open access: yesInternational Journal of Analysis and Applications, 2015
In this paper, continuity and boundedness results for the continuous S-transform in BMO and Hardy spaces are obtained. Furthermore, the continuous S-transform is also studied on the weighted BMO$_k$ and weighted Hardy spaces associated with a tempered

Beggars as Rational Choosers

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT American municipalities increasingly regulate panhandling. That regulation is controversial. The determinants of panhandling activeness are unknown, and it is doubted whether panhandling activity responds rationally to incentives. To shed light on these issues, we collect data on hundreds of panhandlers and the passersby they solicit at ...
