Summary: This study explores the feasibility of using quantile-based measures of relative dispersion as an alternative to the coefficient of variation (CV). The findings suggest that using the interquartile range or the median absolute deviation as robust estimators can yield similar results to the CV, with better robustness to outliers and skewed distributions.

Summary: A large amount of data is being produced every second, and DNA is considered a feasible storage solution due to its high storage density and long-term stability. However, errors are easily made during DNA sequencing and synthesis. To reduce the error rate, a novel address constraint method is proposed, and a DMVO algorithm is used to construct a set of DNA coding. Compared to previous work, the coding set obtained by the DMVO algorithm is larger in size and of higher quality.

Summary: A novel hybrid method utilizing the GBO algorithm to adjust ANFIS hyperparameters was developed for accurate estimation of streamflow in mountainous river basins. The GBO algorithm enhanced ANFIS prediction accuracy compared to other benchmark methods, resulting in significant improvements in predicting monthly streamflows and peak streamflow accuracy. The ANFIS-GBO model also showed higher strength in estimating streamflows from nearby station data as input, outperforming standalone ANFIS models.

Summary: Accurate prediction of air temperature is crucial for weather forecasting. Neural network methods like LSTM and Facebook's Prophet model can adapt to unexpected fluctuations and factors like trends and seasonality in data. This study uses both LSTM and Prophet models to forecast daily air temperatures in Bandung for the next five years. The results show that each model performs better in different temperature ranges, with no significant difference in the RMSE values.

Summary: Efforts are being made worldwide to reduce exposure to air pollution, particularly in developing countries. This study applies a scientometric approach to analyze the current state and trends in air pollution exposure and health research, and identify research solutions and gaps. The analysis reveals the leading role of countries like China and the USA in this field. Topics such as the impact of pollution on climate and health, chemical characteristics and management practices, and health effects of exposure have been extensively researched in the past 5 years.

Summary: With the development of sensors, there is an increasing amount of multimodal data in biomedical and bioinformatics fields. This study proposes a feature-level multimodal fusion model using multi-kernel learning and transfer learning, specifically designed for insufficient training samples. The model achieved better performance compared to baselines in multiple scenarios evaluated using epilepsy EEG data.

Summary: Triple difference is a commonly used estimator in empirical economics research, but its theoretical foundation and assumptions are not universally agreed upon. This paper provides a comprehensive presentation of the triple difference estimator and shows that a causal interpretation can be achieved with just one parallel trend assumption.

Summary: Research has shown that the performance of root mean square error of approximation (RMSEA) is suboptimal for assessing structural equation models with small degrees of freedom (df). This study compares the performance of standardized root mean square residual (SRMR) and comparative fit index (CFI) in small df models with different factor loadings, sample sizes, and model misspecifications. The results indicate that in comparison to RMSEA, SRMR and CFI are less influenced by df and can provide more useful information in differentiating models with varying degrees of misfit. Researchers are advised to exercise caution when interpreting RMSEA for models with small df and rely more on SRMR and CFI.

Summary: In the context of the Covid-19 pandemic, researchers have compared soccer games played in front of empty stadia to those played with fans to understand the impact of spectators. They argue that using the Poisson distribution and bivariate Poisson regression models provides more accurate estimates of the home advantage than linear regression models. Their findings show that the presence or absence of fans can have mixed effects on the home advantage in different soccer leagues, suggesting a complex causal mechanism.

Summary: Loss of power and clear description of treatment differences are important issues in clinical trial design and analysis, especially in nonproportional hazard scenarios. The current ICH E9 (R1) addendum suggests designing trials with clinically relevant estimands, while a combination test proposed by a cross-pharma working group provides robust power under different alternative hypotheses.

Summary: It has been demonstrated that long noncoding RNA (lncRNA) plays crucial roles in human diseases. This study proposes a computational model called LDICDL to identify lncRNA-disease associations using collaborative deep learning. The model utilizes an automatic encoder to denoise multiple lncRNA and disease feature information, and predicts potential associations through matrix decomposition.

Summary: Dealing with structural breaks is crucial in economic research. This article introduces a new toolbox for detecting structural breaks, which is applicable to various panel data and robust to heterogeneity. Applying this toolbox to panel data of 61 countries, a structural break dated to the first week of April is detected, indicating the impact of COVID-19 on stock returns. The reaction of the markets was negative before the break but zero thereafter, possibly influenced by quantitative easing programs announced by central banks.

Summary: The finite-time stability of fractional-order fuzzy cellular neural networks with time delays is investigated. A new fractional-order Gronwall inequality with time delay is developed for the stability analysis of fractional-order delayed systems. A less conservative criterion for the finite-time stability of fractional-order fuzzy cellular neural networks with time delays is derived based on this inequality. Two examples are given to demonstrate the effectiveness and less conservativeness of the proposed results.
