A New Fractional-Order Chaotic System with Different Families of Hidden and Self-Excited Attractors

Entropy, 2018
In this work, a new fractional-order chaotic system with a single parameter and four nonlinearities is introduced. One striking feature is that by varying the system parameter, the fractional-order system generates several complex dynamics: self-excited ...

Seismic Resistant Bridge Columns with NiTi Shape Memory Alloy and Ultra-High-Performance Concrete

Infrastructures, 2020
Reinforced concrete bridge columns often endure significant damages during earthquakes due to the inherent deficiencies of conventional materials. Superior properties of the new materials such as shape memory alloy (SMA) and ultra-high-performance ...

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

PLoS 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

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

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

Ocean 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

APL 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

Earth, 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 ...

Generative Perception of Shape and Material from Differential Motion

CoRR
Perceiving the shape and material of an object from a single image is inherently ambiguous, especially when lighting is unknown and unconstrained. Despite this, humans can often disentangle shape and material, and when they are uncertain, they often move their head slightly or rotate the object to help resolve the ambiguities. Inspired by this behavior,

Shape Conditioned Human Motion Generation with Diffusion Model

CoRR
Human motion synthesis is an important task in computer graphics and computer vision. While focusing on various conditioning signals such as text, action class, or audio to guide the generation process, most existing methods utilize skeleton-based pose representation, requiring additional skinning to produce renderable meshes.
