Reshaping of Gait Coordination by Robotic Intervention in Myelopathy Patients After Surgery

open access: yesFrontiers in Neuroscience, 2018
The Ossification of the Posterior Longitudinal Ligament (OPLL) is an idiopathic degenerative spinal disease which may cause motor deficit. For patients presenting myelopathy or severe stenosis, surgical decompression is the treatment of choice; however ...

Analysis and Experimental Kinematics of a Skid-Steering Wheeled Robot Based on a Laser Scanner Sensor

open access: yesItalian National Conference on Sensors, 2015
Skid-steering mobile robots are widely used because of their simple mechanism and robustness. However, due to the complex wheel-ground interactions and the kinematic constraints, it is a challenge to understand the kinematics and dynamics of such a ...

LiNbO3 Coatings on NCM622: Structure and Performance Insights

open access: yesAdvanced Materials Interfaces, EarlyView.
The amorphous structure of LiNbO3 coatings on LiNi0.6Co0.2Mn0.2O2 (NCM622) cathode active material is systematically investigated by scanning transmission electron microscopy. Theoretical simulations provide insight into the origin of structural transformations observed in the coating at lower calcination temperatures.

Extending Research on Deception in Sport – Combining Perception and Kinematic Approaches

open access: yesFrontiers in Psychology, 2019
The spatio-temporal demands of many high performance sport contexts require a strategic interplay between anticipation from early kinematic cues and the appropriate movement strategy.

Deep Learning-Based Upper Limb Functional Assessment Using a Single Kinect v2 Sensor

open access: yesSensors, 2020
We develop a deep learning refined kinematic model for accurately assessing upper limb joint angles using a single Kinect v2 sensor. We train a long short-term memory recurrent neural network using a supervised machine learning architecture to compensate

Kinematics of deformable media

open access: yes, 2007
We investigate the kinematics of deformations in two and three dimensional media by explicitly solving (analytically) the evolution equations (Raychaudhuri equations) for the expansion, shear and rotation associated with the deformations.

How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.
