Enhance of Energy Harvesting from Transverse Galloping by Actively Rotating the Galloping Body

open access: yesEnergies, 2019
Kinematic rotary control is here proposed conceptually to enhance energy harvesting from Transverse Galloping. The effect of actively orientating the galloping body with respect to the incident flow, by imposing externally a rotation of the body ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

A Novel Fractional-Order Chaotic Phase Synchronization Model for Visual Selection and Shifting

open access: yesEntropy, 2018
Visual information processing is one of the fields of cognitive informatics. In this paper, a two-layer fractional-order chaotic network, which can simulate the mechanism of visual selection and shifting, is established.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Finite element analysis of an actively controlled heavy rotor using a PVDF piezoelectric layer as a sensor and actuator

open access: yesEngineering Reports, 2020
Reduction in the torsional vibration of heavy rotors (eg, turbo‐generator rotors) is important for the safe and efficient functioning of the power plant.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Active Wave Control of a Flexible Using Wave Filters [PDF]

open access: yes, 2013
This report is a review of active wave control of a flexible beam the author has proposed for the last ten years. Conventional active vibration control methods encounter difficulties when the control target is a distributed parameter system which has an ...

Optimization of damage repair with piezoelectric actuators using the Taguchi method

open access: yesFracture and Structural Integrity
Over the last two decades, piezoelectric actuators have emerged as a promising solution for structural repair. In this work, initially the stress intensity factor (SIF) estimation using the finite element (FE) approach at crack tips in aluminium 2024-T3 ...
