Subclinical Neck Pain Alters Gaze Stability During the Vestibulo-Ocular Reflex

open access: yesApplied Sciences
(1) Background: Subclinical neck pain is mild-to-moderate neck pain that has not yet been treated, and where individuals experience pain-free days. Alterations in sensorimotor integration, motor control, proprioception, and cerebellar inhibition have ...

Rapid dynamics of contrast responses in the cat primary visual cortex. [PDF]

open access: yesPLoS ONE, 2011
The visual information we receive during natural vision changes rapidly and continuously. The visual system must adapt to the spatiotemporal contents of the environment in order to efficiently process the dynamic signals.

Estimation-based synthesis of H∞-optimal adaptive FIR filtersfor filtered-LMS problems [PDF]

open access: yes, 2001
This paper presents a systematic synthesis procedure for H∞-optimal adaptive FIR filters in the context of an active noise cancellation (ANC) problem. An estimation interpretation of the adaptive control problem is introduced first.

Effect of adaptive VOR gain changes on OKR gain control.

open access: yesNippon Jibiinkoka Gakkai Kaiho, 1988
ヒトの前庭眼反射系と視運動性眼振系の関連を検討する目的で,左右逆転視,および拡大視による前庭眼反射の適応現象がOKN系に及ぼす影響について検討した.左右逆転視によるVORの適応下では,OKNの利得はVORの利得の低下にほぼ平行して減少し,この結果から,両者はその利得制御系を共有するものと思われた.しかし,拡大視では,VORの利得は増大するものの,OKNの利得には少なくとも今回用いた条件下では影響を与えなかった.

Oculomotor adaptation elicited by intra-saccadic visual stimulation: time-course of efficient visual target perturbation.

open access: yesFrontiers in Human Neuroscience, 2016
Perception of our visual environment strongly depends on saccadic eye movements, which in turn are calibrated by saccadic adaptation mechanisms elicited by systematic movement errors. Current models of saccadic adaptation assume that visual error signals

Modeling and Lyapunov-designed based on adaptive gain sliding mode control for wind turbines [PDF]

open access: yes, 2016
In this paper, modeling and the Lyapunov-designed control approach are studied for the Wind Energy Conversion Systems (WECS). The objective of this study is to ensure the maximum energy production of a WECS while reducing the mechanical stress on the ...

Volitional control of saccadic adaptation.

open access: yesPLoS ONE, 2019
Saccadic adaptation is assumed to be driven by an unconscious and automatic mechanism. We wondered if the adaptation process is accessible to volitional control, specifically whether any change in saccade gain can be inhibited.

Multi-User Hybrid Beamforming Relying on Learning-Aided Link-Adaptation for mmWave Systems

open access: yesIEEE Access, 2019
Hybrid beamforming (HBF) relying on a large antenna array is conceived for millimeter wave (mmWave) systems, where the beamforming (BF) gain compensates for the propagation loss experienced.

Analysis and design of a position observer with stator-resistance adaptation for PMSM drives [PDF]

open access: yes, 2010
This paper deals with reduced-order observers with stator-resistance adaptation for motion-sensorless permanent-magnet synchronous motor drives. An analytical solution for the stabilizing observer gain and stability conditions for the stator-resistance ...
