Abstract Diabetic wounds pose a challenge to healing due increased bacterial susceptibility and poor vascularization. Effective requires simultaneous biofilm elimination angiogenesis stimulation. In this study, we incorporated polyaniline (PANI) S-Nitrosoglutathione (GSNO) into polyvinyl alcohol, chitosan, hydroxypropyltrimethyl ammonium chloride chitosan (PVA/CS/HTCC) matrix, creating versatile wound dressing membrane through electrospinning. The combines the advantages of photothermal...
A greedy nonintrusive reduced order method (ROM) is proposed for parameterized time-dependent problems with an emphasis on in fluid dynamics. The ROM (NIROM) bases a two-level proper orthogonal decomposition to extract temporal and spatial basis from set of candidates, adopts the radial function approximate undetermined coefficients extracted basis.

Collision among barchan dunes is a main cause for the dune swarm to achieve size and speed selection, it can be divided into two patterns: coalescence ejection. Here, three-dimensional (3D) cellular automaton model applied collectively study effects of inter-dune space relative on these collision patterns. A parameter established that includes transition surface distinguishing Confirmed by field observations subaquatic experiments, comprehensive depiction between ejection provided, which may...
After billions of years natural selection, flying animals with flapping wings have superior flight and mobility capabilities. The aerodynamic characteristics the propulsion mechanism bionic attracted a large number researchers because they will be beneficial to novel bio-inspired micro air or underwater vehicle design. Except single activities, for fish, birds, insects, there is very popular interesting biological clustering phenomenon known as schooling. Considering real movements in...
We introduce Seed-TTS, a family of large-scale autoregressive text-to-speech (TTS) models capable generating speech that is virtually indistinguishable from human speech.

To elucidate the influences of varying shapes adjacent roughness elements and inlet free-stream turbulence (FST) on transition within a flat boundary layer, particularly alterations in coherent energetic structures, linear modes, their energy-containing components, direct numerical simulation was conducted flat-plate layer with streamwise-adjacent subjected to FST. We designed two distinct front element configurations four levels Findings indicate that at higher FST levels, energy conversion...
The traditional linear stability analysis for transition prediction includes the following steps: solving velocity profiles using boundary-layer equations or a computational fluid dynamics solver, guessing and searching operations eigenvalues, computing perturbation equations, integrating amplification factor . It is difficult to implement into modern solvers with parallel computations because it requires many nonlocal variables coordinate system transformations. In this Paper, an transport...

Abstract In this study, a novel method for measuring sand creep along flat bed was developed. Specifically, high‐speed digital camera employed to record the movement. With an unsigned image subtraction, new queue could be formed from original experimental images. The particle tracking then calculated, after which velocity and trajectory of grains obtained. addition, fluxes different samples also calculated based on velocities grains.
Particle tracking velocimetry (PTV) algorithms have great applications in discrete particles across successive images. In managing complex flows, classic PTV typically follow delicate concepts that may lead to a higher risk of disturbance caused by the parameter settings. To avoid such 'closure problem', algorithm based on Voronoi diagram (VD-PTV) is developed. This has simple structure, as it designed possess only one controlling parameter. The VD-PTV tested using two types synthetic flows....
