Context-dependent adaptation improves robustness of myoelectric control for upper-limb prostheses.

Journal of neural engineering Jul 10, 2017
OBJECTIVE: Dexterous upper-limb prostheses are available today to restore grasping, but an effective and reliable feed-forward control is still missing. The aim of this work was to improve the robustness and reliability of myoelectric control by usin...

On the Adaptation of Pelvic Motion by Applying 3-dimensional Guidance Forces Using TPAD.

IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society Mar 8, 2017
Pelvic movement is important to human locomotion as the center of mass is located near the center of pelvis. Lateral pelvic motion plays a crucial role to shift the center of mass on the stance leg, while swinging the other leg and keeping the body b...

Effects of adaptation on numerosity decoding in the human brain.

NeuroImage Sep 10, 2016
Psychophysical studies have shown that numerosity is a sensory attribute susceptible to adaptation. Neuroimaging studies have reported that, at least for relatively low numbers, numerosity can be accurately discriminated in the intra-parietal sulcus....

Adaptations to excess choline in insulin resistant and Pcyt2 deficient skeletal muscle.

Biochemistry and cell biology = Biochimie et biologie cellulaire Sep 6, 2016
It was hypothesized that choline supplementation in insulin resistant (IR) CTP:phosphoethanolamine cytidylyltransferase deficient (Pcyt2) mice would ameliorate muscle function by remodeling glucose and fatty acid (FA) metabolism. Pcyt2 mice either re...

Identifying targets of selection in mosaic genomes with machine learning: applications in Anopheles gambiae for detecting sites within locally adapted chromosomal inversions.

Molecular ecology Apr 20, 2016
Chromosomal inversions are important structural changes that may facilitate divergent selection when they capture co-adaptive loci in the face of gene flow. However, identifying selection targets within inversions can be challenging. The high degrees...
