Cardiovascular diseases (CVDs) pose a significant threat to human health due the high mortality and morbidity rates. Traditional drugs often have limited efficacy inherent constraints, such as low bioavailability notable side effects. As highly regarded therapeutic strategy, nanotechnology offers new perspectives means for treating CVDs. Nanozyme-based targeted specifically address biological processes in areas affected by CVDs, thereby achieving precise treatment. Compared traditional...
Growing bacterial biofilms exhibit a number of surface morphologies, e.g., concentric wrinkles, radial ridges, and labyrinthine networks, depending on their physiological status nutrient access. We explore the mechanisms underlying emergence these greatly different morphologies. Ginzburg-Landau kinetic method Fourier spectral are integrated to simulate morphological evolution biofilms. It is shown that instability triggered by stresses induced anisotropic heterogeneous expansion, involves...
Abstract Photonic crystal (PC) not only breaks through the diffraction limit of traditional lenses but also can realize super-resolution imaging. Improving resolution is key task PC The main work this paper to use a graded-index (GPC) flat lens improve image resolution. An air-hole type two-dimensional (2D) GPC structure based on silicon medium proposed in paper. Numerical simulations RSoft reveal that when imaging area air, full width at half maximum (FWHM) value single reaches <mml:math...
This paper proposes a new topology optimization algorithm based on the bi-directional evolutionary structural (BESO) method for design of photonic band gap crystals. The crystals are assumed to be periodically composed two given dielectric materials. Based finite element analysis, proposed BESO gradually re-distributes materials within unit cell until resulting possess maximal at desirable frequency level. Numerical examples both transverse magnetic (TM) and electric (TE) polarizations...
Abstract Based on the two-dimensional dielectric wedge-shaped photonic crystal, we studied existence of two kinds equivalent refractive indexes (negative index is −1, positive 1.897) in crystal by means fast Fourier transform (FFT), as well its influence optical propagation characteristics was discussed. By adjusting wedge angle to eliminate refraction beam imaging, sub wavelength focusing with half-width less than half a can be realized. The numerical results show that Full Width Half...
