First, concept behavior utility trace introduced proposed probability for each action be chosen adjusted according trace, so improve efficiency exploration. Second, attenuation process exploration factor ε designed into two phases,...
To assess whether monocular contrast sensitivity and stereoacuity impairments remain when visual acuity is fully recovered in children with refractive amblyopia.A retrospective review of 487 patients diagnosed amblyopia whose improved to 0.08 logMAR or better both eyes following optical treatment was conducted. Measurements had been made normalized. All treated correction for approximately 2 years diagnosis. No other treatments were provided. Monocular measured using the CSV-1000E chart 6...
The traditional lateral flow immunoassay (LFIA) detection method suffers from issues such as unstable results and low quantitative accuracy. In this study, we propose a novel multi-test line using smartphone-based SAA strips. Following the utilization of image processing techniques to extract analyze pigments on strips, analysis was conducted. Experimental setups with controlled lighting conditions in dark box were designed capture samples smartphones different specifications for analysis....
Phosphafluorenes have drawn increasing attention recently in the applications of organic electronic devices due to their particular optoelectronic properties. To reveal molecular structures, properties, and structure-property relationships newly emerged functional materials, an in-depth theoretical investigation was elaborated via quantum chemical calculations. The optimized geometric structures both ground exited states, mobility hole electron, absorption emission spectra, singlet exciton...
By mimicking the molecular structure of 4,4′-bis(N-carbazolyl)-2,2′-biphenyl (CBP), which is a widely used host material, new series molecules (carbazole-endcapped heterofluorenes, CzHFs) were designed by linking hole-transporting carbazole to core heterofluorene in either meta or para positions heterofluorene. The aromatic cores considered this study are biphenyl, fluorene, silafluorenes, germafluorenes, carbazole, phosphafluorene, oxygafluorene, and sulfurafluorene. To reveal their...
Considering the low indoor positioning accuracy and poor stability of traditional machine-learning algorithms, an indoor-fingerprint-positioning algorithm based on weighted k-nearest neighbors (WKNN) extreme gradient boosting (XGBoost) was proposed in this study. Firstly, outliers dataset established fingerprints were removed by Gaussian filtering to enhance data reliability. Secondly, sample set divided into a training test set, followed modeling using XGBoost with received signal strength...
Perfect vector vortex beams (PVVBs), which are characterized by spiral phase，donut-shaped intensity profile and inhomogeneous polarization of a light beam carrying spin angular momentum (SAM) orbital (OAM), have constant bright ring radius width that unaffected changes in their topological charge (TC)，enabling them highly valuable many optical fields. Metasurfaces, as planar devices composed subwavelength nanostructures, can precisely control the phase, polarization, amplitude...

Abstract Psoriasis is a persistent immune-mediated inflammatory dermatosis. The treatment of psoriasis now features natural medicine as an effective new alternative because its notable effectiveness and few side effects. Nervonic acid (NA), long-chain fatty mostly sourced from the seed oils some wild plants, exhibits significant antidepressant anti-inflammatory properties. Nonetheless, pathogenic effects mechanism NA in pathogenesis are unreported. This work demonstrated that markedly...
