With the emerging Internet of Things, wireless sensor applications are increasingly being supplied from energy harvesting. While this shift away from batteries provides many advantages, it also increases the complexity of designing these highly energy constrained systems. Due to environmental dependencies, novel tools are necessary to support their design process. With the RocketLogger we intro...

We construct an intertemporal model of rent-maximizing behaviour on the part of a timber harvester under potentially multi-dimensional risk as well as geographical heterogeneity. Subsequently, we use recursive methods (in particular, the method of dynamic programming) to characterize the optimal policy function, the rent-maximizing timber-harvesting profile. One noteworthy feature of our applic...

With the rapidly growing number of data publishers, the process of harvesting and indexing information to offer advanced search and discovery becomes a critical bottleneck in globally distributed primary biodiversity data infrastructures. The Global Biodiversity Information Facility (GBIF) implemented a Harvesting and Indexing Toolkit (HIT), which largely automates data harvesting activities fo...

BACKGROUND Annexin V staining is a common tool in apoptosis analysis. However, in adherently growing cell lines, substantial experimental bias could be introduced by membrane damage during the harvesting process. We investigated the influence of three different harvesting methods on the cell membrane integrity of six malignant cell lines. MATERIALS AND METHODS Six malignant cell lines were de...

Harvested energy makes it possible to deploy sensing devices long-term with minimal required upkeep. However, as devices shrink, unpredictable power supplies make it difficult for system designers to anticipate the behavior of these devices. Ekho is tool that records and emulates energy harvesting conditions in order to enable accurate and repeatable testing of these sensing devices. Ekho uses ...

Chimpanzees are renowned for their use of foraging tools in harvesting social insects and some populations use tools to prey on aggressive army ants (Dorylus spp.). Tool use in army ant predation varies across chimpanzee study sites with differences in tool length, harvesting technique, and army ant species targeted. However, surprisingly little is known about the detailed ecology of army ant p...
