Summary: Regulating carbon nanotubes dispersed in the separation layer of membranes is of great importance in improving membrane properties. In this study, ferric oxides coated carbon nanotubes (Fe3O4@CNTs) were prepared and added to the casting solution to prepare composite ultrafiltration membranes. The Fe3O4@CNTs were found to migrate to the separation layer of membranes under a low-intensity magnetic field, resulting in increased surface and overall porosity of the membranes and decreased surface roughness. The composite ultrafiltration membranes exhibited improved hydrophilicity, increased water permeance, high bovine serum albumin rejection, and enhanced antifouling properties.

Summary: This study examines the impact of the COVID-19 pandemic on small businesses in Wuhan, China. The results show that the survival rates of businesses affected by the pandemic is not significantly different from those unaffected. Additionally, businesses that had confidence in their abilities and implemented accurate evaluations of their strategies had a higher probability of survival. Actions such as reducing employees, transitioning operations online, and providing rent subsidies and tax reductions were crucial to maintaining businesses that experienced lockdowns. Governments should provide timely support to small businesses in regions with severe impacts, including grants, loans, and temporary tax cuts.

Summary: A facile route of grafting short chain amino-rich monomers (SCA) onto polyamide (PA) nanofiltration (NF) membrane is proposed for efficient Li+/Mg2+ separation. The SCA grafted NF membrane (PA-g-SCA) shows a more uniform distribution of positively charged groups on the pristine PA layer, leading to high rejection of Mg2+ and high permeation of Li+, resulting in superior Li+/Mg2+ separation performance with a separation factor of 130 even in a high WMg2+/Li+ of 200:1.

Summary: A high-performance loose nanofiltration (LNF) membrane with high water permeance and high separation accuracy was fabricated by regulating the polymer chain entanglements through changing the size of nano-CaCO3 in the casting solution. The entanglements of the polymer chains were characterized by the solution viscosity, which increased with the decrease of nano-CaCO3 size and reduced when nano-CaCO3 disappeared. The high solution viscosity and rapid phase inversion resulted in the formation of LNF membranes with outstanding performance.

Summary: KNN classification is a non-deterministic learning mode that requires setting a suitable K value and searching for the K nearest neighbors from the entire training sample space to make predictions. This paper proposes a one-step computation method to replace the lazy part of KNN classification by transforming it into a matrix computation. The method fits the training samples to the test data using the least squares loss function, generates a relationship matrix based on the influence of the training samples on the test data, and performs sparse learning using group lasso. A new classification rule is also proposed to improve the performance of one-step KNN classification. Experimental results demonstrate the efficiency and potential of this one-step KNN classification approach.
