Mechanical properties of tubulin intra- and inter-dimer interfaces and their implications for microtubule dynamic instability.

open access: yesPLoS Computational Biology, 2019
Thirteen tubulin protofilaments, made of αβ-tubulin heterodimers, interact laterally to produce cytoskeletal microtubules. Microtubules exhibit the striking property of dynamic instability, manifested in their intermittent growth and shrinkage at both ...

Dual-taper modular hip implant: Investigation of 3-dimensional surface scans for component contact, shape, and fit

open access: yesArthroplasty Today, 2018
Background: The etiology of wear particle generation and subsequent corrosion in modular total hip arthroplasty implants likely begins with mechanical fretting.

General Automatic Human Shape and Motion Capture Using Volumetric Contour Cues [PDF]

open access: yes, 2016
Markerless motion capture algorithms require a 3D body with properly personalized skeleton dimension and/or body shape and appearance to successfully track a person. Unfortunately, many tracking methods consider model personalization a different problem and use manual or semi-automatic model initialization, which greatly reduces applicability.

Direct recovery of motion and shape in the general case by fixation [PDF]

open access: yes[1990] Proceedings Third International Conference on Computer Vision, 1992
A direct method called fixation is introduced for solving the general motion vision problem: arbitrary motion relative to an arbitrary environment. This method results in a linear constraint equation that explicitly expresses the rotational velocity in terms of the translational velocity.

Capturing, classification and concept generation for automated maintenance tasks [PDF]

open access: yes, 2014
Maintenance is an efficient and cost effective way to keep the function of the product available during the product lifecycle. Automating maintenance may drive down costs and improve performance time; however capturing the necessary information required ...

Relation between trees of fragmenting granules and supergranulation evolution

open access: yes, 2016
Context: The determination of the underlying mechanisms of the magnetic elements diffusion over the solar surface is still a challenge. Understanding the formation and evolution of the solar network (NE) is a challenge, because it provides a magnetic ...

A global summary of seafloor topography influenced by internal-wave-induced turbulent water mixing [PDF]

open access: yesOcean Science
Turbulent water motions are important for the exchange of momentum, heat, nutrients, and suspended matter, including sediments in the deep sea. The motions occur in a deep sea that is generally stably stratified in density.

Epithelial vertex models with active biochemical regulation of contractility can explain organized collective cell motility

open access: yesAPL Bioengineering, 2018
Collective motions of groups of cells are observed in many biological settings such as embryo development, tissue formation, and cancer metastasis. To effectively model collective cell movement, it is important to incorporate cell specific features such ...

Source process of the 2016 Kumamoto earthquake (Mj7.3) inferred from kinematic inversion of strong-motion records

open access: yesEarth, Planets and Space, 2017
In this study, we estimated source process of the 2016 Kumamoto earthquake from strong-motion data by using the multiple-time window linear kinematic waveform inversion method to discuss generation of strong motions and to explain crustal deformation ...
