Thin layer chromatography and column chromatography were performed from the ethyl acetate extraction of the bark stem of Phyllanthus acidus, and six terpenoids were isolated, including four diterpenes and two triterpenes. Their names were phyllanthol (1), 19-acetoxy-16α, 17- dihydroxy-ent-kaurane (2), 16α, 17-dihydroxy-ent-kaurane (3), 16α,17-acetonide-3αhydroxykauran (4), maslinic acid (5) and phyllane A (6).

To solve this problem, we use an improved genetic algorithm named GA-RT (Genetic Algorithm with Random Crossover and Negative Tournament Selection) and conduct experiments on the iMOPSE standard dataset. Experimental results show that the proposed GA-RT algorithm can effectively solve the project scheduling problem, achieving better performance compared to existing algorithms.

Hypertrophic cardiomyopathy (HCM) is a common genetic cardiovascular disease and a major cause of sudden death. It is also involved in increasing morbidity and mortality of various cardiovascular diseases. Genetic factors have been found to be important in determining the phenotypic manifestation of cardiac hypertrophy. However, only 50–60% of HCM patients have been identified as having pathogenic variants in known genes, suggesting that more studies are needed to find more disease genes.

One-loop contributions to the decay process \(H \to Z*\gamma \to {v_e}{v_e} \gamma \) in standard model are performed in the paper "One-loop contributions to in standard model \(H \to Z*\gamma \to {v_e}{v_e} \gamma \)". The detailed computations are carried out in unitary gauge. In physical results, we present numerical results for partial decay width and its distribution. We find that the partial decay width is given to 0.466 KeV. This result is in the upper bound of the current experimental data at the Large Hadron Collider.

This study aims to contribute to the development of a GaN/Ga2O3 diode that can be utilized in high-power device applications. The simulated device is calibrated against experimental GaN and Ga2O3 diodes, considering the effect of thickness of GaN layer and its doping concentration on the performance of GaN/Ga2O3 diodes. The band structures of devices are investigated to revial which factors that affect the properties of GaN/Ga2O3 diode.

The study which applies quantitative methods along with the support of EVIEWS software points out a statistical significance relationship. Firstly, the CS has a contrariwise impact on ROA but no effect on ROE and ROS. Secondly, among control variables (asset structure, expenditure ratio, revenue), the expenditure ratio is the only one showing a contrariwise impact on ROS and the rest has no statistical significance.

Creating credit is the main income-generating activity for banks. However, granting credit always comes with risks. Credit risk is the risk of losing part or all of a debt due to failure to pay on time or default. Credit risk is considered the most important risk affecting banking performance. Therefore, this study measured the effect of credit risk on the financial performance of Vietnamese commercial banks.
