Exciton polaritons formed by the strong coupling between excitons and photons have been extensively studied in transition metal disulfides (TMDs) for their potential to inherit ultralong radiation lifetime and remarkable nonlinearity. Many studies have achieved strong coupling at room temperature. However, the systems in these studies generally lack orderly characteristics and precise controllability, and their tunability also remains rather limited.

By combining the molecular beacon-based fluorescence-activated droplet sorting (FADS) utilized for random library screening with site-directed mutagenesis aimed at facilitating conformational changes in T7 RNAP, we successfully identified four mutants that exhibit reduced dsRNA content: M1 (V214A), M7 (F162S/A247T), M11 (K180E) and M14 (A70Q). Furthermore, the combinatorial mutant M17 (A70Q/F162S/K180E) exhibited significantly reduced dsRNA production under various conditions.

This work revealed the effects of endogenous proteins on the structural, physicochemical, and digestive properties of starch in corn before and after ripening and explored the binding mechanism of proteins with starch. The microstructure showed that the postharvest ripening process resulted in a thinning of the protein layer on the surface of starch particle. After the removal of protein, the uniformity of the sample surface increased, with tiny pores.

View Article and Find Full Text PDFPatch features obtained by fixed convolution kernel have become the main form in hyperspectral image (HSI) classification processing. However, the fixed convolution kernel limits the weight learning of channels, which results in the potential connections between pixels not being captured in patches, and seriously affects the classification performance. To tackle the above issues, we propose a novel Adaptive Pixel Attention Network, which can improve HSI classification by further mining the connections between pixels in patch features.
View Article and Find Full Text PDFFew-shot learning (FSL) uses prior knowledge and supervised experience to effectively classify hyperspectral images (HSIs), thereby reducing the cost of large numbers of labeled samples. However, existing few-shot methods ignore the correlation between cross-domain feature channels, and the feature representation ability is insufficient. To address above issue, this paper proposes a novel Residual Channel Attention Based Sample Adaptation Few-Shot Learning for Hyperspectral Image Classification(RCASA-FSL) for hyperspectral image classification (HSIC), which can capture and enhance cross-domain dependencies through multi-layer residual connection and random-based feature recalibration.

Impulsivity and emotion impairments have been noted in individuals with gambling disorder (GD). However, little research has investigated the influence of impulsivity and emotions on the severity of gambling in clinical populations. This study aimed to examine: (i) differences in emotions and impulsivity traits according to the severity of gambling in individuals with GD, (ii) the mediating effects of emotion in the relationship between impulsivity traits and gambling severity, and (iii) the predictive effects of emotion and impulsivity traits on GD severity.

In this study, we investigated the infection rate, the influence and the early predictors of EBV infection in SFTS patients.
Methods: In this retrospective study, SFTS patients who were treated in the First Affiliated Hospital of Nanjing Medical University from May 2011 to August 2021 were enrolled and divided into infected and non-infected groups.
Plant proteins have the advantages of low cost and high yield, but they are still not comparable to animal proteins in processing due to factors such as gelation and solubility. How to enhance the processing performance of plant proteins by simple and green modification means has become a hot research topic nowadays. Based on the above problems, we studied the effect of gel induction on its properties.

Despite the high pH levels (7 to 11) in the study area, which generally inhibits heavy metal solubility, we found that regular changes in water levels still affect Pb-Zn movement. Soil analysis revealed distinct redox zones within the unconfined aquifer, as shown by the variable Fe/Mn and Ce/Ce* ratios.

Sodium dodecyl sulfate (SDS) treatment all significantly affected the starch content, molecular weight of proteins, relative crystallinity, pasting characteristics and dynamic viscoelasticity in samples before and after postharvest ripening. In the corn that had not undergone postharvest ripening, there were also significant electrostatic interactions and hydrogen bonds between starch and protein.

Immune checkpoint inhibitors (ICIs) have effectively eradicated advanced tumors by inducing durable and systematic antitumor immune responses. However, when used as a standalone treatment, ICIs typically exhibit a low response rate in many cancers. In this study, we engineered an -formed gel depot using elastin-like polypeptides (ELPs) to efficiently deliver PD-L1 antibodies (aPD-L1) and gemcitabine (GEM) for enhanced immunotherapy in melanoma.

The newly harvested Jidan 66 (JD66) and Liangyu 99 (LY99) varieties of corns were stored for 56 days at constant temperature of 15 and 25 °C with relative humidity of 55%. The postharvest ripening resulted in more disordered secondary structure and less compact tertiary conformation of zein. The emulsifying activity and foaming stability reached maximum after storage of corns at 15 and 25 °C for 14 days, while the emulsifying stability and foaming capacity were the highest at two temperatures of storage for 7 days and 28 days, respectively.
