Resonant DC-DC converters are a class of strongly nonlinear systems with rich phenomena. In order to describe the dynamic behavior resonant more accurately, fractional (FO) is studied deeply, based on nature inductance and capacitance. Firstly, Sigmoid function state model converter established integrated phase shift control. A discrete by using an estimation correction algorithm. Secondly, mathematical equivalent circuit models constructed in MATLAB. The simulations experimental results...
The nonlinear dynamic characteristics of a peak current regulation fractional-order (FO) flyback converter, considering the fractional nature inductance and capacitance, are investigated in detail. First, discrete iterative model converter under 10 kHz operating conditions is accomplished using application Generalized Euler Method (GEM). On this basis, bifurcation diagrams, phase simulated time domain diagrams used to describe behavior converter. dynamics through diagram analyses. A...
With the rapid development of inland river navigation and upgrading waterways, attention is being paid to optimization standardization ship types. Twin-skeg ships are well adapted restricted but multiple working conditions complex hull lines surfaces these make difficult. This study takes a 7500 DWT twin-skeg bulk carrier, uses CAESES model control hull, STAR-CCM+ predict total resistance uniformity wake field, kriging method establish approximate with respect ship's field. Sensitivity...
Amyloid-β peptide (Aβ)-induced cholinergic system and mitochondrial dysfunction are major risk factors for Alzheimer's disease (AD). Our previous studies found that carnosic acid (CA), an important polyphenol antioxidant, could significantly delay Aβ1-42-mediated acute paralysis. However, many details underlying mechanisms of CA's neuroprotection against Aβ-induced defects remain unclear. Herein, we deeply investigated the effects possible CA-mediated protection Aβ toxicity in vivo through...
Compared with monometallic selenides, bimetallic selenides have better synergistic effects and more abundant active sites for electrochemical reactions. As an important member of the transition metal oxide family, NiCoSe2 has been widely used in energy storage devices shown excellent performance. So this paper, nitrogen-doped carbon decorated composites (NiCoSe2/NC-700, NiCoSe2/NC-800, NiCoSe2/NC-900) a microflower structure were synthesized by calcining nickel-cobalt organic skeleton...
Nanobodies (Nbs) have great potential in immunoassays due to their exceptional physicochemical properties. With the immortal nature of Nbs and ability manipulate structures using protein engineering, it will become increasingly valuable understand what structural features drive high stability, affinity, selectivity. Here, we employed an anti-quinalphos Nb as a model illustrate basis Nbs' distinctive properties recognition mechanism. The results indicated that Nb-11A-ligand complexes exhibit...
This paper addresses the problem of robust H 2 and ∞ control discrete linear time-invariant (LTI) systems with polytopic uncertainties via dynamic output feedback. The has been known to be difficult when a parameter dependent Lyapunov function is applied for less conservative design due non-convexity. Our approach based on novel bounding technique that converts non-convex optimization into convex one together line search, which simple but may conservative. To further reduce conservatism, an...

Interaction of two identical excitable spiral waves in a bilayer system is studied. We find that the can be completely synchronized if coupling strength sufficiently large. Prior to complete synchronization, we new type weak synchronization between coupled systems, i.e., wave driven has same geometric shape as driving but with much lower amplitude. This general behavior, called projective waves, similar nonlinear oscillators, which been extensively studied before. The underlying mechanism...
