Learning multi-level topology representation for multi-view clustering with deep non-negative matrix factorization.

Clustering of multi-view data divides objects into groups by preserving structure of clusters in all views, requiring simultaneously takes into consideration diversity and consistency of various views, corresponding to the shared and specific components of various views. Current algorithms fail to fully characterize and balance diversity and consistency of various views, resulting in the undesirable performance. Here, a novel Multi-View Clustering with Deep non-negative matrix factorization and Multi-Level Representation (MVC-DMLR) learning is proposed, which integrates feature learning, multi-level topology representation, and clustering of multi-view data.

Thienothiophene-Benzopyran Derivative and AQ4N-Assembled Liposomes for Near-Infrared II Fluorescence Imaging-Guided Phototherapy, Chemotherapy, and Immune Activation.

Phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), has attracted wide attention in tumor treatment. However, the hypoxic tumor microenvironment and the heat shock proteins produced by tumor cells significantly reduce their efficacy. Developing effective phototherapy agents that have high reactive oxygen species generation efficiency and photothermal conversion efficiency (PCE) while simultaneously utilizing the hypoxic tumor microenvironment is of great importance.

Regulating Room-Temperature Phosphorescence of Organic Luminophores Through Stepwise Stabilization by Coordination and In-Situ Precipitation Reaction.

Developing efficiency and long-lived room-temperature phosphorescence (RTP) materials through straightforward methods is highly desired. In this work, a stepwise stabilization strategy was proposed by the coordination and in-situ precipitation reactions among organic precursors, inorganic cation and anions, producing room-temperature phosphorescence materials with high emission efficiency (phosphorescence quantum yield of 45 %). Structural and photophysical characterizations revealed the coordination reaction reduced the energy gaps between singlet and triplet states and stabilized the excited states of the guest molecules.

H1N1 swine influenza viruses upregulate NEU1 expression through histone H3 acetylation regulated by HDAC2.

Mammalian membrane sialic acid is the key receptor for influenza virus. Sialidases, the main type of enzyme that can hydrolyze membrane sialic acids in mammalian cells, have the potential to affect the invasion process of influenza viruses, including H1N1. For the first time, this study focused on the regulation mechanism of sialidase NEU1 expression, and revealed that swine-origin influenza (H1N1) virus infection can promote NEU1 expression through histone H3 acetylation, which is regulated by HDAC2 in host cells.

Engineering Heterointerface to Synergistically Regulate Kinetics and Stress of Copper-Cobalt Selenide toward Reversible Magnesium/Lithium Hybrid Batteries.

Metal chalcogenide-based cathodes are crucial for the development of rechargeable magnesium batteries, yet the strong electrostatic interactions of Mg result in slow ion transport and high polarization. The Mg/Li hybrid battery holds promise for enhancing the energy storage capability. Herein, we establish a system that utilizes (Co,Cu)Se/CoSe heterostructure grown on carbon cloth as the cathode and APC-LiCl as a dual-salt electrolyte to achieve high reversible capacity, enhanced cyclic stability, and impressive rate performance.

Connecting the liquid fragility to the average weakest metal-oxygen bond of its crystal in oxides.

Glass and crystal are inherently different material states in terms of their structural and physical features; consequently, the direct quantitative connection between crystal and glass is lacking. Herein, we first show that the liquid fragility m, which is featured by the negative departure degree of viscosity with the temperature at the glass transition temperature (Tg), has a direct exponential correlation with the ratio of the average longest metal-oxygen and the average phosphorus, silicon, or boron-oxygen bond lengths of the crystal in various oxides including phosphates, silicates, and borates. Such a result can be rationalized by the fact that the fragility m in these glass-formers is associated with the total network rigidity determined by the weakest bond due to the "bucket effect" and the bond pair inheritance of glass from that of the crystal.
