Wikipedia's inclusive editorial policy permits unrestricted participation, enabling individuals to contribute and disseminate their expertise while drawing upon a multitude of external sources. News media outlets constitute nearly one-third of all citations within Wikipedia. However, embracing such a radically open approach also poses the challenge of the potential introduction of biased content or viewpoints into Wikipedia. The authors conduct an investigation into the integrity of knowledge within Wikipedia, focusing on the dimensions of source political polarization and trustworthiness. Specifically, the authors delve into the conceivable presence of political polarization within the news media citations on Wikipedia, identify the factors that may influence such polarization within the Wikipedia ecosystem and scrutinize the correlation between political polarization in news media sources and the factual reliability of Wikipedia's content.

The authors conduct a descriptive and regression analysis, relying on Wikipedia Citations, a large-scale open dataset of nearly 30 million citations from English Wikipedia. Additionally, this dataset has been augmented with information obtained from the Media Bias Monitor (MBM) and the Media Bias Fact Check (MBFC).

The authors find a moderate yet significant liberal bias in the choice of news media sources across Wikipedia. Furthermore, the authors show that this effect persists when accounting for the factual reliability of the news media.

The results contribute to Wikipedia’s knowledge integrity agenda in suggesting that a systematic effort would help to better map potential biases in Wikipedia and find means to strengthen its neutral point of view policy.

The sudden COVID-19 epidemic in 2019 has frustrated China's overall economy, and the implementation and development of the National Fitness Program has encountered huge obstacles. At a new historical starting point, in order to realize the dream of becoming a powerful country in sports, it is necessary to transform the successful experience gained since the reform and opening up into regular understanding and systematic theories, so as to make a theoretical response to the new contradictions and challenges faced in development and give full play to the National Fitness has comprehensive values and multiple functions in improving people's health, promoting people's all-round development, promoting economic and social development and demonstrating the country's cultural soft power.

Taking the topic of national fitness as an example, this paper sets out from the three dimensions of knowledge input, knowledge output and knowledge production, using citation analysis, social network analysis, co-word analysis and cluster analysis, to measure the characteristics and knowledge structure of interdisciplinary knowledge exchange.

China's national fitness is still in the primary development stage, and the strong boost of the national top-level policy is the biggest driving force of its development, driven by the policy together with the settlement of many major events, constantly improving and enriching the wings. The main body of knowledge production on the topic of national fitness is mainly colleges and universities, with low participation of government and enterprises, high degree of cooperation among authors, obvious interdisciplinary characteristics and strong application of research themes.

This study provides a strong theoretical basis for the promotion of the Healthy China strategy. Especially under the influence of COVID-19, this paper can contribute to the comprehensive value and multimodal functions of national fitness in improving the health of people, promoting economic and social development and demonstrating the soft power of national culture.

Traditional simulation research of geological and similar engineering models, such as landslides or other natural disaster scenarios, usually focuses on the change of stress and the state of the model before and after destruction. However, the transition of the inner change is usually invisible. To optimize and make models more intelligent, this paper aims to propose a perceptible design to detect the internal temperature change transformed by other energy versions like stress or torsion.

In this paper, micron diamond particles were embedded in 3D printed geopolymers as a potential thermal sensor material to detect the inner heat change. The authors use synthetic micron diamond powder to reinforced the anti-corrosion properties and thermal conductivity of geopolymer and apply this novel geopolymer slurry in the direct ink writing (DIW) technique.

As a result, the addition of micron diamond powder can greatly influence the rheology of geopolymer slurry and make the geopolymer slurry extrudable and suitable for DIW by reducing the slope of the viscosity of this inorganic colloid. The heat transfer coefficient of the micron diamond (15 Wt.%)/geopolymer was 50% higher than the pure geopolymer, which could be detected by the infrared thermal imager. Besides, the addition of diamond particles also increased the porous rates of geopolymer.

In conclusion, DIW slurry deposition of micron diamond-embedded geopolymer (MDG) composites could be used to manufacture the multi-functional geological model for thermal imaging and defect detection, which need the characteristic of lightweight, isolation, heat transfer and wave absorption.

This study aimed to determine the relationship between calorie and macronutrients intake and the growth status of Aboriginal children based on gender and age group.

This was a cross-sectional study participated by 85 school-aged Aboriginal children at Labu, Negeri Sembilan. The dietary intake and socioeconomic status data were collected from the parents using an interviewer administrated structured-questionnaire and 24-hour dietary recall. WHO AnthroPlus software was used to determine the z-score of weight for age (WAZ), height for age (HAZ) and body mass index (BMI) for age (BAZ).

The mean fat intake was significantly higher among younger children (i.e. 7–9 years old) as compared to elder children (i.e. 10–12 years old) (40.7 ± 17.3 g vs 32.0 ± 13.8 g; t = 2.496, p = 0.015) but not for the mean intake of calorie (1816.1 ± 979.9 kcal vs 1566.3 ± 808.7 kcal; t = 1.248, p = 0.216), protein (50.13 ± 20.08 g vs 44.94 ± 16.45 g; t = 1.269, p = 0.208) and carbohydrates (198.0 ± 63.0 g vs 190.8 ± 66.1 g; t = 0.513, p = 0.609). The majority of the respondents did not meet recommended nutrient intake (RNI) for the calorie (65.9%) and fat (75.3%). A significantly higher proportion of elder children did not meet RNI for fat as compared to younger children (88.8% vs 65.3%; X² = 6.21, p = 0.021). The HAZ showed that 28.2% (n = 24) of the Aboriginal children were stunted, while WAZ showed that 14.8% (n = 9) of the Aboriginal students were underweight, and 8.2% of them were overweight. Based on BAZ classification, 15.4% (n = 6) of boys and 2.2% (n = 1) of girls were overweight. There is no significant correlation between calories and macronutrients and growth status of the children.

Although the under-nutrition status among Aboriginal children is still a highlighted issue, the few over-nutrition statuses among Aborigines should be taken into count, especially in term of energy and macronutrient intake.
