Self-supervised graph representation learning has recently shown considerable promise in a range of fields, including bioinformatics and social networks. A large number of graph contrastive learning approaches have shown promising performance for representation learning on graphs, which train models by maximizing agreement between original graphs and their augmented views(i.e., positive views). Unfortunately, these methods usually involve pre-defined augmentation strategies based on the knowledge of human experts. Moreover, these strategies may fail to generate challenging positive views to provide sufficient supervision signals. In this paper, we present a novel approach named graph pooling contrast(GPS) to address these *** by the fact that graph pooling can adaptively coarsen the graph with the removal of redundancy, we rethink graph pooling and leverage it to automatically generate multi-scale positive views with varying emphasis on providing challenging positives and preserving semantics, i.e., strongly-augmented view and weakly-augmented view. Then, we incorporate both views into a joint contrastive learning framework with similarity learning and consistency learning, where our pooling module is adversarially trained with respect to the encoder for adversarial robustness. Experiments on twelve datasets on both graph classification and transfer learning tasks verify the superiority of the proposed method over its counterparts.

By combining experimental α-decay energies and half-lives, the α-particle preformation factor for nuclei around neutron magic numbers N of 126, 152, and 162 were extracted using the two-potential approach. The nuclei around the shell closure were more tightly bound than adjacent nuclei. Additionally, based on the WS4 mass model (Wang et al., Phys. Lett.B 734, 215 (2014)), we extended the two-potential approach to predict the α-decay half-lives of nuclei around N values of178 and 184 with Z of 119 and 120. We believe that our findings will serve as guidelines for future experimental studies.

To elucidate the adsorption characteristics and retention mechanisms of fracturing fluids in diverse clay minerals, we conducted on-line nuclear magnetic resonance(NMR) and atomic force microscopy(AFM)experiments. The depth and extent of solid phase damage are determined by the ratio between the size of fine fractions in fracturing fluid residue and the pore-throat size in experiments. Poor physical properties(K 0.5 m D) combined with a scattered distribution of retained fracturing fluid is associated with high gas phase recovery permeability, whereas a continuous sheet-like distribution results in low recovery permeability. The expansive surface area and presence of filamentous illite minerals facilitate the multiple winding and adsorption of fracturing fluids, demonstrating strong hydrogen-bonding, multi-layering and multiple adsorption properties. The geological characteristics of the main gas formations exhibit significant variation, and the severity of damage caused by fracturing fluids occurs in diverse sequences. To address this issue, a differentiated strategy for optimizing fracturing fluids has been proposed.

Objective To investigate the inhibitory effect of Tanreqing Injection(TRQ)on the activation of nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3(NLRP3)inflammasome in macrophages infected with influenza A virus and the underlying mechanism based on mitophagy *** The inflammatory model of murine macrophage J774A.1 induced by influenza A virus[strain A/Puerto Rico/8/1934(H1N1),PR8]was constructed and treated by TRQ,while the mitochondria-targeted antioxidant Mito-TEMPO and autophagy specific inhibitor 3-methyladenine(3-MA)were used as controls to intensively study the anti-inflammatory mechanism of TRQ based on mitophagy-mitochondrial reactive oxygen species(mtROS)-NLRP3 inflammasome *** levels of NLRP3,Caspase-1 p20,microtubule-associated protein 1 light chain 3 Ⅱ(LC3Ⅱ)and P62 proteins were measured by Western *** release of interleukin-1β(IL-1β)was tested by enzyme linked immunosorbent assay,the mtROS level was detected by flow cytometry,and the immunofluorescence and co-localization of LC3 and mitochondria were observed under confocal laser scanning *** Similar to the effect of Mito-TEMPO and contrary to the results of 3-MA treatment,TRQ could significantly reduce the expressions of NLRP3,Caspase-1 p20,and autophagy adaptor P62,promote the expression of autophagy marker LC3II,enhance the mitochondrial fluorescence intensity,and inhibit the release of mtROS and IL-1β(all Pming the type of *** TRQ could reduce the level of mtROS by promoting mitophagy in macrophages infected with influenza A virus,thus inhibiting the activation of NLRP3 inflammasome and the release of IL-1β,and attenuating the inflammatory response.
