Effects of Parkinson’s disease on optic flow perception for heading direction during navigation [PDF]
, 2014 Visuoperceptual disorders have been identified in individuals with Parkinson’s disease (PD) and may affect the perception of optic flow for heading direction during navigation.

Head Module Control of Mediator Interactions [PDF]
Molecular Cell, 2006 Yeast Mediator proteins interacting with Med17(Srb4) have been expressed at a high level with the use of recombinant baculoviruses and recovered in homogeneous form as a seven subunit, 223 kDa complex. Electron microscopy and single-particle analysis identify this complex as the Mediator head module.

Surface ship heading control with sideslip angle and input saturation
Zhongguo Jianchuan Yanjiu, 2021 ObjectivesTo address the impact of non-zero sideslip angle and input saturation on the heading control of a surface ship, a method based on a backstepping control algorithm is proposed.Methods The actual sideslip angle is obtained through the relative ...

Dynamic control of head mesoderm patterning [PDF]
Development, 2011 The embryonic head mesoderm gives rise to cranial muscle and contributes to the skull and heart. Prior to differentiation, the tissue is regionalised by the means of molecular markers. We show that this pattern is established in three discrete phases, all depending on extrinsic cues.

Translational control from head to tail [PDF]
Current Opinion in Cell Biology, 2009 mRNA translation, a highly coordinated affair involving many proteins and RNAs, is generally divided into three steps: initiation, elongation, and termination. Each of these steps serves as a point of regulation to control the amount of protein that is produced.

Design of submarine heading sliding mode controller based on NESO
Zhongguo Jianchuan Yanjiu, 2018 [Objectives] To realize submarine steering control with low noise when a submarine sails on a surface in a complex sea state, [Methods] a heading controller is designed based on linear motion model on horizontal plane.
