Design and Motion Performance of an Underwater Two-Stage Towed System with Active Heave Compensation

open access: yesJournal of Marine Science and Engineering
Underwater towed survey systems are widely used for marine observation, resource exploration, and target identification. While high-speed towing is increasingly required to improve operational efficiency, conventional single-stage towed systems face a ...

Design and movement trail analysis of a life testing machine for self-lubricating rod end spherical plain bearing of a helicopter

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
In this paper, a new type of mechanism in a life testing machine for self-lubricating rod end spherical plain bearing of a helicopter is proposed based on the main rotor structure and motion process of a single rotor helicopter with hinged blades.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Control of a Dynamic Driving Simulator: Time-Variant Motion Cueing Algorithms and Prepositioning [PDF]

open access: yes, 2006
This thesis mainly addresses the task to provide the driver of a dynamic driving simulator with the same motion cues as would occur in reality. The DLR Driving Simulator, which is the subject matter of this thesis, uses a hexapod motion platform to ...

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

open access: yesFEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Workspace Optimization of the Robocoaster Used as a Motion Simulator [PDF]

open access: yes, 2009
The RoboCoaster is a theme park ride based on a serial chain industrial robot. Apart from its use as an entertainment device it can also be used for motion simulation such as flight or driving simulation.

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome

open access: yesFEBS Letters, EarlyView.
In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...

Evaluation by simulation of interpolation and acceleration algorithms for Stepper Motors [PDF]

open access: yes, 2005
Stepper motors are used to control CNC machines for many applications. As well as following the required path precisely, it is also important that the motion be smooth and that the surface speed be controllable.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
