Ship heading and trajectory control method based on L1-GPR

Zhongguo Jianchuan Yanjiu
ObjectivesIntelligent ships at sea are influenced by environmental interference, and the influence of the uncertainty of model parameters leads to the problem of low ship motion control accuracy, so it is necessary to improve the resistance of the ship's

Head Controlled Mouse

International Journal of Computer Applications, 2012
The basic idea of the projects is to build a human machine interface which can be used to control mouse using head-tilt and eye-blink. This mouse-emulating device can be found to be most useful by physically handicapped people who can no longer control the computers using their hands.

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.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Heading and Path-Following Control of Autonomous Surface Ships Based on Generative Adversarial Imitation Learning

Journal of Marine Science and Engineering
Autonomous ship control faces significant challenges due to the diversity of ship types, the complexity of task scenarios, and the uncertainty of dynamic marine environments.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Resilient event-triggered practically predefined-time heading control of ships with delay of steering gear and false-data-injection attacks

Automatika
The presence of time delays prevents the controller from responding to disturbances promptly, resulting in excessive overshoot and prolonged settling times.

A Geometric Approach to Head/Eye Control

IEEE Access, 2014
In this paper, we study control problems that can be directly applied to controlling the rotational motion of eye and head. We model eye and head as a sphere, or ellipsoid, rotating about its center, or about its south pole, where the axes of rotation are physiologically constrained, as was proposed originally by Listing and Donders.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
