Generalized head movement

open access: yesProceedings of the Linguistic Society of America, 2018
We argue for a unified account of head movement and lowering in which lowering is in essence the covert movement counterpart of head movement. This proposal is supported by the existence of successive cyclic lowering (evidenced by relative prefix formation in Ndebele), in which complex heads built by lowering have the Mirror-Principle-obeying structure

A hybrid 3d reconstruction/registration algorithm for correction of head motion in emission tomography [PDF]

open access: yes, 2000
Even with head restraint, small head movements can occur during data acquisition for emission tomography, sufficiently large to result in detectable artifacts in the final reconstruction.

Two-Way Automata Making Choices Only at the Endmarkers

open access: yes, 2011
The question of the state-size cost for simulation of two-way nondeterministic automata (2NFAs) by two-way deterministic automata (2DFAs) was raised in 1978 and, despite many attempts, it is still open.

Neural Representations for Sensory-Motor Control, III: Learning a Body-Centered Representation of 3-D Target Position [PDF]

open access: yes, 1993
A neural model is described of how the brain may autonomously learn a body-centered representation of 3-D target position by combining information about retinal target position, eye position, and head position in real time.

Vision-Based Measurement of Heart Rate from Ballistocardiographic Head Movements Using Unsupervised Clustering

open access: yesSensors, 2019
Heart rate has been measured comfortably using a camera without the skin-contact by the development of vision-based measurement. Despite the potential of the vision-based measurement, it has still presented limited ability due to the noise of ...

Voluntary presetting of the vestibular ocular reflex permits gaze stabilization despite perturbation of fast head movements [PDF]

open access: yes
Normal subjects are able to change voluntarily and continuously their head-eye latency together with their compensatory eye movement gain. A continuous spectrum of intent-latency modes of the subject's coordinated gaze through verbal feedback could be ...

GazeMap: Dual-Pathway CNN Approach for Diagnosing Alzheimer’s Disease from Gaze and Head Movements

open access: yesMathematics
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that impairs cognitive function, making early detection crucial for timely intervention.

Persistent perceptual delay for head movement onset relative to sound onset with and without vision [PDF]

open access: yes, 2017
Knowing when the head moves is crucial information for the central nervous system in order to maintain a veridical representation of the self in the world for perception and action.

Head-Tail Clouds: Drops to Probe the Diffuse Galactic Halo

open access: yes, 2011
A head-tail high-velocity cloud (HVC) is a neutral hydrogen halo cloud that appears to be interacting with the diffuse halo medium as evident by its compressed head trailed by a relatively diffuse tail.

Doubling and do-support in verbal fronting: Towards a typology of repair operations

open access: yesGlossa, 2017
Most known languages seem to follow the intuitive and economical implication that if they show a repair such as verb doubling or do-support when just the verb is fronted, they also show that same repair when the verb is fronted together with its internal
