In this paper, stochastic resonance (SR) is exploited within a tristable electromechanical coupled system to enhance energy harvesting. Assuming that the effective capacitance of piezoelectric element can be neglected, equations are converted second-order differential equation. Using adiabatic approximation and linear response theory, spectral amplification equivalent mechanical obtained characterize SR. It observed exhibits maximum as function nonlinear stiffness coefficients noise...
Stochastic resonance (SR) and stochastic bifurcations are investigated numerically in a nonlinear tri-stable system driven by colored noise harmonic excitation. The power spectral density, signal-to-noise ratio, stationary probability density (SPD), largest Lyapunov exponent (LLE) calculated to quantify SR, P-bifurcation, D-bifurcation, respectively. effects of parameters, such as intensity correlation time, well-depth damping coefficient, on SR explored. Numerical results show that both...
Abstract Color tuning is a fascinating and indispensable property in various applications. Thus far, variety of reconfigurable approaches have been implemented to achieve color change. However, it still challenge enable continuous over the entire hue range simple, stable, rapid manner without changes configuration material properties. Here, an all‐optical continuously tunable plasmonic pixel scheme demonstrated via modular design approach realize polarization‐controlled full by breaking...
Poly(L-lactic acid) (PLLA) is a promising material for bone substitutes due to its biodegradability and biocompatibility. However, limited osteogenic activity antibacterial properties restrict applications. To address these challenges, this study develops PLLA/SiO2@ZnO/PDA/PLL composite fibrous materials using an approach that integrates electrospinning with ultrasonic techniques. The exhibits photothermal functionality osteoinductive properties. demonstrates excellent hydrophilicity,...
Motivated by the existing difficulties in establishing mathematical models and observing state time series for some complex systems, especially those driven non-Gaussian Lévy motion, we devise a method extracting governing laws with observations only on mean exit time. It is feasible to observe certain systems. With such observations, use sparse regression technique least squares sense obtain approximated function expression of Then, learn generator further identify stochastic differential...
Vortex beams, carrying orbital angular momentum (OAM), have great potential to increase the information capacity of optical communication systems for orthogonality and infinite mode number. For OAM beams propagating in free space, however, atmospheric turbulence may cause distortions hinder their utilization practice. In this work, we propose a kind diffractive deep neural network (D2NN) compensate distorted beams. Different from those D2NNs reported before, here is dissipative, rather than...
OBJECTIVE Little is known about the relationship between changing psychosocial work conditions and type 2 diabetes. We determined whether stressors coping resources affect risk of RESEARCH DESIGN AND METHODS In this prospective cohort (2003–2014) 3,740 workers without diabetes (OHSPIW [Occupational Health Study Petroleum Industry Workers]), participants completed an evaluation work-related stress diagnosis at baseline 12 years follow-up (two waves). The changes in were measured with...
Abstract The piezoelectric and electromagnetic hybrid vibration energy harvester (HVEH) has proven to be a favorable option deal with the low power generation issue overcome drawbacks of each individual transduction mechanism. Besides, colored Lévy noise consisting small perturbations, large jumps, correlation time turns out relatively suitable tool for describing complex environments. For purpose enhancing harvesting performance HVEH, stochastic dynamics induced by in tri-stable HVEH is...
Resonance between light and object is highly desired in optical manipulation because the forces reach maximum values this case. However, traditional waveguide structures, resonant interaction also greatly perturbs incident field weakens or completely destroys on subsequent particles. In order to avoid dilemma, we propose perform a topological photonic structure. Owing protection, mode can almost keep its original form when an being manipulated. Therefore, sorting be achieved multiple high...
Laguerre–Gaussian (LG) mode is widely adopted in various applications due to carrying orbital angular momentum (OAM). In practice, it challenging sort according features. Traditional fork grating and optical geometric transformations are regarded as convenient methods for sorting LG mode. However, these have destroy the OAM carried by beam during process. Here, we demonstrate a nondestructive mechanism momentums based on translation operator. The numerically solved operator can input beams...
Intent on developing efficient proton exchange membranes used for direct methanol fuel cells as well hydrogen cells, a series of based sulfonated polyetheretherketone and polyphosphazene‐graft copolymers is prepared by cross‐linking reaction because the former material has good enough mechanical property, while latter excellent in transfer. The cross‐linked combine advantages two kinds polymers. Among them, membrane poly[(4‐trifluoromethylphenoxy)(4‐methylphenoxy)phosphazene]‐g‐poly...
