Summary: Multimodal data analysis is used for identifying sample categories by incorporating supervised information and capturing the nonlinear correlated structures across different views. The proposed architecture, discriminative deep canonical correlation analysis (D2CCA), combines generative models with the learning objective to improve discriminative ability. The joint representation of multi-view data is learned from maximally correlated subspaces.

Summary: The paper proposes a method of robust deflated canonical correlation analysis via feature factoring for multi-view image classification, which introduces a feature factoring matrix to evaluate the contribution of each feature to the whole feature space and assign specific weights to different features to suppress noisy data. Multiple factoring matrices are built with respect to multiple projection vectors to weigh the degree of importance of each feature in each projection for better feature representation in multi-view images.

Summary: This study compared the correlation and relative contribution of multiple abiotic factors to the different aspects of beta-diversity in macroinvertebrates from 179 stream sampling sites in the Hun-Tai River Basin in Northeastern China. The results showed that functional beta-diversity provides important complementary information to taxonomic and phylogenetic beta-diversity. Spatial factors were found to be more influential than local environmental and geo-climatic variables in shaping the beta-diversity of stream macroinvertebrates.

Summary: Trait-based approaches are increasingly used in ecology to understand the influence of individual-level trait variation on communities and species. This study examined the responses of individual trait variation of the diatom genus Aulacoseira to environmental changes in the Pearl River Delta. The results showed that different factors regulated the trait richness, trait evenness, and trait dispersion of Aulacoseira, with abiotic factors having a stronger direct influence than biotic factors. This study highlights the potential of multidimensional trait variation as an effective indicator for tracking environmental changes.

Summary: In recent years, many 2D hydrodynamic models have incorporated the direct rainfall method (DRM) to serve as hydrological-hydrodynamic models for floodplain determination. However, the role of catchment hydrological processes (CaHyPro) and its interaction with the calibration process have not been thoroughly investigated. In this case study, the spatiotemporal distribution of precipitation and runoff formation processes, combined with the 2D model HEC-RAS, is examined. A conceptual approach for event-based interflow is also integrated. The results demonstrate the improvement in model accuracy through the integration of CaHyPro and its interplay with calibrated model parameters.

Summary: This paper analyzes the study of microplastics and their impact on aquatic ecosystems, focusing on trends, focal points, and national collaborations in freshwater microplastics research. The findings reveal three stages of microplastics research and a shift in research focus. International cooperation has increased, but the scope of collaboration is still limited. Future research should consider the bi-directional relationship between microplastics and watershed ecosystems and incorporate chemical and toxicological approaches.

Summary: Changes in land use and land cover significantly influence river water quality. This study utilized spatial data from 39 catchments in the southern basin of the Caspian Sea to investigate the impact of landscape structure on water quality. The findings reveal that landscape structure metrics, particularly the shape index, contiguity index, and fractal metric, can predict variations in total dissolved solids (TDS) and magnesium (Mg) concentrations. Optimizing landscape structure metrics in land use planning can help reduce river pollution and improve water quality.

Summary: Biodiversity loss caused by human activities poses a threat to human well-being, but the combined effects of multiple stressors on community diversity, both alpha and beta, are not well understood. A long-term experiment on the Songhua River in China from 2012 to 2019 revealed a decline in alpha and beta diversity indices, particularly in impacted river sections. Despite improved water quality, human-caused stressors have led to biotic homogenization of macroinvertebrate communities, with land use being a significant factor. Different facets of diversity have distinct response mechanisms to stressors, providing complementary information in assessing ecological changes. This study highlights the importance of long-term monitoring and the need for timely control of nutrient input and land use expansion to protect river ecosystems.
