Diatom‐Inspired 1D Immobile Robots Capable of 2D Collective Mobility

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a diatom‐inspired robotic system that explores group coordination through limited physical interactions. The researchers tune groups of Barbots, simple robotic agents that possess neither individual mobility nor explicit communication capabilities, to achieve complex and adaptive collaboration based on environmental light.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Effect of storage time and type of packaging on seed quality of tall fescue [PDF]

open access: yesJournal on Processing and Energy in Agriculture, 2012
After harvesting, the seed dormancy of grasses occurs. During the maturing period, seed dormancy is slowly reduced, and seed germination reaches the maximum values of use. Germination decreases during longer storage.
