A Distributed Multirobot Architecture for Decoupled Inspection and Localized Treatment in Precision Agriculture

open access: yesAdvanced Intelligent Systems, EarlyView.
A distributed multirobot architecture enables asynchronous vineyard inspection and localized treatment through a cloud‐based mission control center. Real‐world validation demonstrates reliable coordination of heterogeneous robots, accurate disease detection, and effective conversion of georeferenced observations into targeted treatment actions ...

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Study of warm compaction behavior for titanium alloy powder

open access: yes, 2005
The warm compaction behavior of the titanium alloy powder was studied in the present paper. The results show that warm compacting temperature have great influence on the green density of titanium alloys. At the optimum of 140 degrees C, the green density

Risk management externalities in agrifood supply chains

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Reducing deep soil compaction through strain modification under different wheel arrangements

open access: yes, 2002
New mechanisation methods associated with increasing loads have the potential to cause undesirable deep compaction, which is difficult, expensive and in some cases impossible to alleviate.

Evaluation of Warm-Mix Asphalt Compaction Performance by Variable-Temperature Gyratory Compaction

open access: yes, 2020
: For dynamic changes of viscosity reducing mechanism of different types of additives in after mixing mixture, the Warm-Mix Asphalt would present different compaction performance development with the change of paving temperature and time.

A mouse model of mechanical stress injury to the basal ganglia using thermosensitive PNIPAM hydrogel for intracerebral hemorrhage research

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

Selective Cell‐Repellent 3D Scaffold Platform for Proton Radiobiology

open access: yesAdvanced NanoBiomed Research, EarlyView.
A selective cell‐repellent 3D scaffold platform is developed to minimize unwanted 2D cell populations surrounding engineered cell microenvironments. The approach is based on the combination of Lipidure coatings with two‐photon polymerized scaffolds and enables specific characterization of glioblastoma cells’ response to proton irradiation.

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.
