Hydrological modeling outputs are subject to uncertainty resulting from different sources of errors (e.g., error in input data, model structure, and model parameters), making quantification of uncertainty in hydrological modeling imperative and meant to improve reliability of modeling results. The uncertainty analysis must solve difficulties in calibration of hydrological models, which further increase in areas with data scarcity. The purpose of this study is to apply four uncertainty analysis algorithms to a semi-distributed hydrological model, quantifying different source of uncertainties (especially parameter uncertainty) and evaluate their performance. In this study, the Soil and Water Assessment Tools (SWAT) eco-hydrological model was implemented for the watershed in the center of Vietnam. The sensitivity of parameters was analyzed, and the model was calibrated. The uncertainty analysis for the hydrological model was conducted based on four algorithms: Generalized Likelihood Uncertainty Estimation (GLUE), Sequential Uncertainty Fitting (SUFI), Parameter Solution method (ParaSol) and Particle Swarm Optimization (PSO). The performance of the algorithms was compared using P-factor and Rfactor, coefficient of determination (R (2)), the Nash Sutcliffe coefficient of efficiency (NSE) and Percent Bias (PBIAS). The results showed the high performance of SUFI and PSO with P-factor > 0.83, R-factor 0.91, NSE > 0.89, and 0.18 < PBIAS < 0.32. Hence, we would suggest to use SUFI-2 initially to set the parameter ranges, and further use PSO for final analysis. Indeed, the uncertainty analysis must be accounted when the outcomes of the model use for policy or management decisions.

This article explores the integration of Eastern and Western perspectives on the use of dexamethasone and N-acetylcysteine as premedications in transarterial chemoembolization for hepatocellular carcinoma(HCC).By examining key concerns raised by Western researchers,particularly regarding the different etiologies of liver cirrhosis,and contrasting them with robust clinical data from Asia,this article highlights the necessity for region-specific research and proposes future directions for global HCC management.

In this study, selenium nanoparticles (SeNPs) were synthesized using Annona glabra leaf extract as a reducing agent. In addition, the solution-casting method was employed to prepare the food preservation film from the chitosan-Andrographis paniculata extract-selenium nanoparticles (CS-APE-Se). The effects of SeNPs with different contents (equivalent to 1, 2, 3, and 4% of chitosan mass) on fundamental properties and bioactivities of the films were also tested. According to the results, the prepared films possess good biodegradability after 30 days of burial. Besides, the antioxidant activity of the material was also investigated via free radical scavenging toward 2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2 '-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), which showed the inhibition rate up to 45 and 82%, respectively. Additionally, the antibacterial performance of the films was assessed against Staphylococcus aureus and Pseudomonas aeruginosa, which indicated the highest antibacterial capacity with the inhibition diameter of 18.1 +/- 0.03 and 19.25 +/- 0.01 mm, respectively. Furthermore, the coating of the CS-APE-Se films also effectively prevented physical damage and prolonged the shelf life of the strawberries by up to 10 days. The aforementioned results demonstrated the potential for applying chitosan (CS) film in combination with Andrographis paniculata leaf extract and SeNPs as a secure alternative to the harmful chemicals currently used in food preservation.
