Direct Drive Brush-Shaped Tool with Torque Sensing Capability for Compliant Robotic Vine Suckering.

In this paper, we present a direct drive brush-shaped tool developed for the use of robotic vine suckering. Direct drive design philosophy allows for precise and high bandwidth control of the torque exerted by the brush. Besides limiting the torque exerted onto the plant, this kind of design philosophy allows the brush to be used as a torque sensor.

Heterogeneous Autonomous Robotic System in Viticulture and Mariculture: Vehicles Development and Systems Integration.

There are activities in viticulture and mariculture that require extreme physical endurance from human workers, making them prime candidates for automation and robotization. This paper presents a novel, practical, heterogeneous, autonomous robotic system divided into two main parts, each dealing with respective scenarios in viticulture and mariculture. The robotic components and the subsystems that enable collaboration were developed as part of the ongoing HEKTOR project, and each specific scenario is presented.

Precise Yet Uncertain: Broadening Understandings of Uncertainty and Policy in the BPA Controversy.

Bisphenol A (BPA) is one of the most studied and most controversial chemicals used by the food packaging industry, because of its endocrine disruptive properties. Part of the controversy is due to the uncertainty that surrounds the effects of BPA on the endocrine system. Uncertainty includes data gaps, methodological hurdles, incompatibilities between toxicology and endocrinology-based approaches, and so on.

Isolated yet open: A metabolic analysis of Menorca.

Small islands are vulnerable to climate change, and at the same time contribute to local and global environmental problems with the intensification of tourist activities. Whereas there are many studies on the resource requirements or environmental impacts of small islands, there are few efforts to integrate information that is often analysed separately. Metabolic analysis, beyond quantifying biophysical flows, studies how society transforms these flows to reproduce the identity of the whole.

Cognitive impairment and depression after acute myocardial infarction: associations with ejection fraction and demographic characteristics.

Cognitive impairment and depression are often associated with acute myocardial infarction, however, the risk factors for their occurrence after myocardial infarction are still unclear. To determine the effect of reduced ejection fraction and demographic characteristics on the occurrence of cognitive impairment and depression after myocardial infarction. In the prospective study, the final sample consisted of 82 patients.
