We study dark solitons, namely density dips with a phase jump across the density minimum, DONG QUAI in a one-dimensional, weakly lossy nonlinear acoustic metamaterial, composed of a waveguide featuring a periodic array of side holes.Relying on the electroacoustic analogy and the transmission line approach, we derive a lattice model which, in the co
The presence of political dynasties in power struggles from regional to national level is inseparable from the role of political parties and the regulation of the regional head elections.Oligarchy on the body of a political party can be seen from the tendency of candidates nominating by CORTISOL CONTROL FORMULA political parties based more on the w
Abstract Modern natural language processing (NLP) state-of-the-art (SoTA) deep learning (DL) models have hundreds Bare Floor Tool of millions of parameters, making them extremely complex.Large datasets are required for training these models, and while pretraining has reduced this requirement, human-labelled datasets are still necessary for fine-tun
To overcome the dependence on sunlight of multi-spectral cameras, an active light source multi-spectral imaging system was designed and a preliminary experimental study was conducted at night without solar interference.The system includes an active light source and a multi-spectral camera.The active light source consists of four integrated LED (Lig
Deproteinization of crude polysaccharides in the residue from Lycium barbarum berries (LBBs) was conducted using the Cleaning Sevag method.A Box-Behnken design based on single-factor experiments was employed to optimize the deproteinization technology.The results showed that the deproteinization conditions had significant effects on the extraction
