A Robotic System to Deliver Multiple Physically Bimanual Tasks via Varying Force Fields

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022
Individuals with physical limb disabilities are often restricted to perform activities of daily life (ADLs). While efficacy of bilateral training has been demonstrated in improving physical coordination of human limbs, few robots have been developed in ...

Understanding the Liquid States of Cyclic Hydrocarbons Containing N, O, and S Atoms via the 3D-RISM-KH Molecular Solvation Theory

open access: yesMolecules, 2022
The 3D-reference interaction site model (3D-RISM) molecular solvation theory in combination with the Kovalenko–Hirata (KH) closure is extended to seven heterocyclic liquids to understand their liquid states and to test the performance of the theory in ...

Avian Information Systems: Developing Web-Based Bird Avoidance Models

open access: yesEcology and Society, 2008
Collisions between aircraft and birds, so-called "bird strikes," can result in serious damage to aircraft and even in the loss of lives. Information about the distribution of birds in the air and on the ground can be used to reduce the risk of bird ...

Surfaces, Interfaces and Crystal Growth of Marcasite FeS2 [PDF]

open access: yesMaterials Research, 2021
Marcasite mineral is a metastable iron sulphide, α-FeS2, less known and less abundant than pyrite β-FeS2. Their chemical compositions are similar, formed by S22- dimers and Fe2+ species, but the marcasite crystal structure is orthorhombic while pyrite is

Discordant tasks and motor adjustments affect interactions between adaptations to altered kinematics and dynamics

open access: yesFrontiers in Human Neuroscience, 2010
Motor control and adaptation are multi-determinate processes with complex interactions. This is reflected for example in the ambiguous nature of interactions during sequential adaptation of reaching under kinematics and dynamics perturbations.
