We present a pipeline for the visual localization and classification of agricultural pest insects by computing saliency map applying deep convolutional neural network (DCNN) learning. First, we used global contrast region-based approach to compute localizing insect objects. Bounding squares containing targets were then extracted, resized fixed size, construct large standard database called Pest ID. This was utilized self-learning local image features which were, in turn, DCNN. DCNN learning...

Two-way fixed effects (TWFE) models are widely used for causal panel analysis in political science. However, recent methodological advancements cast doubt on the validity of TWFE estimator presence heterogeneous treatment (HTE) and violations parallel trends assumption (PTA). In response, researchers have proposed a variety novel estimators testing procedures. Our study aims to gauge these issues empirical science research evaluate practical performance new proposals. We undertake review,...

Simonsohn (2024a) and (2024b) critique Hainmueller, Mummolo Xu (2019, HMX), arguing that failing to model nonlinear relationships between the treatment moderator leads biased marginal effect estimates uncontrolled Type-I error rates. While these critiques highlight issue of under-modeling nonlinearity in applied research, they are fundamentally flawed several key ways. First, causal estimand for interaction effects necessary identifying assumptions not clearly defined critiques. Once...

This study aimed to investigate the working experiences and perceptions of hospital-based, pediatric medical social workers in China. Eight were interviewed. There three primary themes extracted through analysis: (1) negative experience perceived work challenges workers; (2) positive sense professional benefit for (3) development needs profession. While Chinese have encountered several difficulties challenges, they also benefited from work. Furthermore, provided constructive recommendations...

Brassinosteroids (BR) and Arbuscular mycorrhizas (AM) symbiosis play an important role in improving plant growth development. Previous studies have shown that there is a complex regulatory network between phytohormones AM symbiosis.

Public green spaces (PGSs) play a positive role in urban social sustainability and solidarity, as all dwellers can access them without discrimination or restrictions, but urbanization usually leads to an extreme shortage of PGSs thus it becomes important spatial resource that is competed for by different groups, especially migrant populations. Taking the Macau Peninsula example, this study employed hybrid analysis approach, including Gini coefficient, share index quality assessment, look at...

The dynamics of nonstructural carbohydrates (NSC) profoundly affect productivity and ecological adaptability to adversity in plants. Global warming induced the frequent occurrence extreme precipitation events that altered winter snow pattern deserts. However, there is a lack understanding how desert mosses respond long-term cover change at NSC level. Therefore, this study, (7-years) removal (-S), ambient (CK), double (+S) experiments were set field investigate content its component...

This paper uses time series to study the impact of industrial structure upgrading and unemployed poor population on China's economic development. The final results show that main reason for slow growth rate social development is number continues rise. Through literature reading data analysis, it found continuous rise in China "Lewis turning point" has been crossed, quantity labor supply decline, which leads lack comprehensive improvement quality practical supply.

GDP is an important indicator to measure a country's economic situation. However, with the development of our society, can no longer represent real situation country’ economy, since it does not take into account sustainability country’s development. Thus, green GDP, also known as GGDP came being. only measures achievements in past, but its ability sustainable future. Based on linear regression model GGDP, this paper analyzes factors that may affect and further discusses influences
