Luminescent responsive heterostructures with region-domained emission and integrated responsiveness exhibit great potential in information security, but always suffer from the direct exposure of fingerprint information at the initial state, making it easy to decode the hidden confidential information. Herein, the first monochromatic responsive hydrogen-bonded organic framework (HOF) heterostructures are reported based on VIA-group-based framework hybridization toward fully-covert photonic barcodes. Designed HOF blocks with different VIA-group elements are integrated via a configuration-assimilation-based assembly method to generate the intrinsic monochromatic HOF heterostructures.

The method offers several advantages: eliminates the formation of regioselective by-products and avoids the use of high temperatures and nitric acid. The last step of the overall route enables gentle hydrolysis of phenyl esters with methanol and potassium carbonate, which greatly reduces the occurrence of side reactions.

Although UNet is widely used in medical imaging, its performance is limited by the inherent drawbacks of convolutional neural networks (CNNs), such as restricted receptive fields and limited global context modeling, which affect segmentation efficiency.
Method: 712 patients with mediastinal lesions admitted to Shanghai General Hospital between October 2014 and January 2023 were included in the study.
Understanding the structure-activity relationship on a solid surface is crucial for developing an efficient low-temperature NH-SCR catalyst. Herein, an in-depth investigation was conducted on a single-atom Mn-doped α-FeO catalyst by combining experimental studies and density functional theory calculations. Mn doping not only facilitates N-H cleavage in the Eley-Rideal (E-R) pathway but also promotes the adsorption of NO and the cleavage of the N-O bond, lowering the energy barrier of the rate-determining step in the Langmuir-Hinshelwood (L-H) pathway.

Understanding the incidence and risk factors of GDM is crucial for early prevention and management, especially in underrepresented areas like Guizhou Province, China, where geographic and ethnic diversity may influence the disease's prevalence and risk profiles.
Aim: To investigate the incidence of GDM and identify its associated risk and protective factors among different ethnic groups in Guizhou Province, providing essential data for early prevention strategies.
Acute myeloid leukemia (AML) is a heterogeneous cancer, making outcomes prediction challenging. Several predictive and prognostic models are used but have considerable inaccuracy at individual level. We tried to increase prediction accuracy using a multi-omics strategy.

In this work, we developed the amino group-assisted atomic layer deposition strategy to deposit the atomically dispersed Pt on SiO support for the first time, in which the particle size and ratio of Pt entities from single atom (Pt) to atomic cluster (Pt ) and nanoparticle (Pt ) on the SiO surface were well modulated. We demonstrated the importance of dual-site synergy for optimizing the activity of single-atom catalysts.

Using our unique PCa patient-derived xenograft (PDX) dormancy models, we investigated this critical dormant phase and discovered a selective increase in B7-H4 expression during the dormancy period following mouse host castration. This finding is supported by observations in clinical specimens of PCa patients treated with ADT.

The positive relationship between species richness and area is a fundamental principle in ecology. However, this pattern deviates on small islands, where species richness either changes independently of area or increases at a slower rate-a phenomenon known as the Small-Island Effect (SIE). While the SIE has been well documented in natural ecosystem, its presence in highly fragmented and disturbed urban ecosystem remains unexplored, posing challenges for urban vegetation conservation.

Herein, based on the molecular imprinting technology, this study proposed a ratiometric fluorescence sensor employing the "post-doping" strategy, which aims to be rapid, selective, and visually easy-to-use for CIP detection to address antibiotic residues and environmental risks. Specifically, by exploiting the "antenna effect" of lanthanide metal ions (Ln), terbium (III) (Tb) chosen as a fluorescence-assisted functional monomer as well as the red emitting CdTe quantum dots (QDs) as the internal reference signal were introduced into multi-emission Tb-CdTe@SiO@MIPs (TbMIPs).
