Through two theoretical lenses, the Health Belief Model (HBM) and literature explaining conspiracy theories, this study examined media discourse about Human Papillomavirus (HPV) vaccine in China's cyberspace. Results showed that narratives are positive but misleading, HBM components presented inconsistently over time. The also identified emerging theories HPV vaccine: Chinese theorists accused Western countries of using to destroy ethnic group. These findings demonstrate influence public...
The phosphate adsorption mechanisms of SA-0.4La@De involved electrostatic interactions, ligand exchange, and the formation La–P complexes.
We perform a search of double beta decay $^{136}$Xe to the excited state, $0^+_1$, $^{136}$Ba (2$\nu \beta \beta$-0$_1^+$), using dual-phase xenon detector PandaX-4T with first 94.9-day commissioning data. The multi-site events are reconstructed up MeV energy scale, which helps improve background model significantly. contribution from stainless steel platform outside cryostat is evaluated for time. No significant evidence 2$\nu \beta$-0$_1^+$ observed, resulting in lower limit $T_{1/2}^{2...
As a new type of promising semiconductor photocatalyst, SnO2 cannot be widely applied due to its low utilization efficiency visible light and swift recombination photogenerated electrons holes. These drawbacks were effectively overcome by preparing the B/Ag/F tridoped SnO2-ZnO composite films using simple sol–gel method. The degradation methyl green formaldehyde solutions was used value photocatalytic activity samples. Photoluminescence (PL) spectra UV–Vis absorption spectroscopy results...
Aqueous gelcasting for 0.94Bi 0.5 Na TiO 3 –0.06BaTiO (BNBT6) lead‐free piezoceramics was investigated in this paper. A stable BNBT6 suspension with 50 vol% of solid loading and <1Pa·s viscosity successfully prepared when wt% PMAA‐NH 4 added the pH value controlled range 8–10. Dehydration desiccation gelled parts could be easily through dipping pretreatment a 5 ammonium persulfate solution 24 h or 10 12 h. Scanning electron microscopy micrographs show that ceramic by route exhibits...
The segmentation of off-line cursive handwriting is an important step in recognition. In this paper, a new approach described for task. suggested uses set heuristic rules to determine possible letter boundaries the image word. are based on associations that exist between certain geometric and topologic features English language characters. A system incorporating proposed has been built perform postal address images. includes several preprocessing steps extract handwritten words from envelope...
This paper studies the task of image captioning with novel objects, which only exist in testing images. Intrinsically, this can reflect generalization ability models understanding and semantic meanings visual concepts objects unseen training set, sharing similarity to one/zero-shot learning. The critical difficulty thus comes from that no paired images sentences be used help train model. Inspired by recent work (Chen et al. 2019b) boosts one-shot learning generate various deformations, we...
Abstract Predicting the activity of solar flares is great significance for studying its physical mechanism and impact on human production life. Problems such as class imbalance, high time-series sensitivity, over-localization important features exist in sample data used flare forecasting. We design a fusion method based resampling CNN-GRU algorithm to try solve above problems. In order verify effectiveness this method, first, we compared forecast performance different methods by keeping...
Abstract This study presents a generalized version of the residual differential item functioning (RDIF) detection framework in response theory, named GRDIF, to analyze (DIF) multiple groups. The GRDIF retains advantages original RDIF framework, such as computational efficiency and ease implementation. performance was assessed through simulation compared with existing DIF methods, including Mantel‐Haenszel, Lasso‐DIF, alignment methods. Results showed that demonstrated well‐controlled Type I...
Establishing the identify of a signature by automatic search through database signatures is interest in several areas. This paper describes system for this purpose. The proposed identification uses set geometric and topologic features to characterize each signature. By considering spatial distribution these features, maps into two strings finite symbols. A local associative indexing scheme then used on organize collection known identity. When presented with unknown identity, same retrieve...
