Friction Observer and Compensation for Control of Robots with Joint Torque Measurement [PDF]

, 2008
In this paper we introduce a friction observer for robots with joint torque sensing (in particular for the DLR medical robot) in order to increase the positioning accuracy and the performance of torque control.

Temporal Shifts in Subtidal Rocky Benthic Communities Associated With the Invasion of Rugulopteryx okamurae in a Port Environment

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The invasive brown alga Rugulopteryx okamurae, native to the northwestern Pacific, has rapidly expanded along the European Atlantic coast, reaching the Basque Coast in 2023, and was likely already present in 2022. Using annual data from a monitoring survey conducted between 2010 and 2025, this study assesses the spatio‐temporal variability of ...

Vibrio Community Structure Shapes the Diversity of Carbenicillin‐Hydrolysing Class A β‐Lactamase Circulating in European Coastal Environments

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Vibrio communities shape carbenicillinase diversity in European coasts. Sediments serve as reservoirs of antibiotic‐resistant Vibrio alginolyticus, which can move into the water column and accumulate in bivalves. This spreads β‐lactamase resistance and raises human exposure risks to antibiotic‐resistant pathogenic Vibrio, especially as higher seawater ...

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Spread and Population Dynamics of Rugulopteryx okamurae Across the Azores Archipelago (NE Atlantic)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Rugulopteryx okamurae is a recently introduced brown macroalga that has expanded rapidly across the Azores (NE Atlantic). This study provides an update of the archipelago‐wide spatial spread and the first assessment of its local population dynamics.

Spatiotemporal Quantification of Rugulopteryx okamurae in Beach Wrack Using UAV Multispectral Remote Sensing

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Excessive beach accumulations of stranded macrophytes, also known as wrack, are a growing challenge for coastal ecosystems and management, particularly when dominated by invasive species. The Asian brown alga Rugulopteryx okamurae has rapidly proliferated along the southern coast of Spain, causing significant ecological and socioeconomic ...

Covariates influence optimal camera‐trap survey design for occupancy modelling

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 169-182, April 2026.
We investigated the impact of covariates (e.g., habitat quality, temperature) on the optimal design of camera trap surveys to estimate species occupancy. Using simulations of a virtual species, we found that increasing the number of cameras consistently reduced error across a range of covariate effects.

The Seasonal Impact of the Island Mass Effect on Coastal Biogeochemistry and Phytoplankton Assemblage: The Case of the Tropical and Volcanic Island of Guadeloupe (French West Indies)

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The Island Mass Effect (IME) in tropical regions remains understudied, despite its potential to fertilize oligotrophic oceanic gyres and impact on higher trophic levels. Guadeloupe provides an ideal case study of IME due to its diverse nutrient sources, dual exposure to the Caribbean Sea on the western coast and Atlantic Ocean on the eastern ...

Perceived organizational exploitation and employee health: An examination of processes and boundary conditions

Journal of Occupational and Organizational Psychology, Volume 99, Issue 1, March 2026.
Abstract Recent research has argued that exploitative working relationships can be present in any context and experienced by any employee, and their forms can range from extreme to subtle. Drawing on the Conservation of Resources theory, we argue that, through the depletion of resources, employees' perceived organizational exploitation is likely to ...

A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

Advanced Functional Materials, Volume 36, Issue 9, 29 January 2026.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...
