The identification of plant disease is the premise prevention efficiently and precisely in complex environment. With rapid development smart farming, becomes digitalized data-driven, enabling advanced decision support, analyses, planning. This paper proposes a mathematical model detection recognition based on deep learning, which improves accuracy, generality, training efficiency. Firstly, region proposal network (RPN) utilized to recognize localize leaves surroundings. Then, images...

The problem of salvo attack multiple missiles without time-to-go estimation has been addressed by a two-stage guidance scheme in this correspondence. In the first stage, simple decentralized control law is designed to provide desired initial conditions (target-missile relative range and velocity lead angle) for latter stage. As second all are governed classical pure proportional navigation law. Numerical simulations under two-dimensional (2-D) 3-D cases demonstrate effectiveness proposed formulation.

As pesticide abuse becomes increasingly serious worldwide, it is necessary to pay attention the biopesticide adoption behavior of agricultural producers. It worth verifying whether cooperatives, as training organizations sharing same social network with farmers, can promote biopesticides through their technology diffusion function. Therefore, based on survey data 837 citrus producers in Sichuan Province, China, IV-probit regression model and a mediation effects were used empirically test...

The intensification of global climate change leads to frequent mountain torrents, landslides, debris flows and other disasters, which seriously threaten the safety residents’ lives property. However, few studies have compared analyzed livelihood vulnerability adaptation strategies farmers in different disaster-threatened areas under background change. Based on survey data 327 households threatened by floods, landslides flow Sichuan Province, this study characteristics disaster types...

Abstract To meet the requirements of high‐quality safe products, starter cultures are used to produce fermented sausages. The effects 3 commercial cultures, namely SM‐194, T‐SPX, and SM‐181, on histamine accumulation quality parameters including microbial quality, pH, water activity, total volatile base nitrogen, as well color texture properties, were evaluated during fermentation ripening Although initial counts Escherichia coli , Enterobacteriaceae, Pseudomonas similar in 4 batches, growth...

This study explores the impact of farmland transfer on multidimensional relative poverty elderly in rural areas to provide a reference for land China and improve welfare system elderly. Based Family Panel Studies (CFPS) sample data 2018, this paper uses AF index measurement method assess areas. Logit regression estimation examines single older adults transferred from poverty, using propensity score matching (PSM) analyze results' robustness. The agricultural has different impacts indicators...

Abstract Because of the reductions in China’s cultivated land area and significant impact on agricultural market, main grain-producing areas (MGPA) policy has become vitally important for ensuring food security. However, guaranteed security sustainability require ecological security, which raises question whether production should come at expense environment. This study used 1998–2020 panel data from 30 Chinese provinces a spatial difference-in-differences model (SDID) to explore MGPA...

For residents living in earthquake-threatened areas, choosing suitable risk coping behaviors can effectively reduce the loss of family life and property. However, some still choose to continue live within areas at earthquake disaster. Place attachment may play an important role. Based on place theory Protective Action Decision Model (PADM), this study explores possible relationships among attachment, efficacy beliefs, evacuation/relocation intention. Furthermore, it examines mediating role...

Extreme precipitation events (EPE) often cause catastrophic floods accompanied by serious economic losses and casualties. The latest version (V06) of the Integrated Multi-satellite Retrievals for Global Precipitation Measurement (GPM IMERG) provides global satellite data from 2000 at a higher spatiotemporal resolution with improved quality. It is scientifically practically important to assess accuracy IMERG V06 in capturing extreme precipitation. This study evaluates two widely used products...

With the successful completion of battle against poverty, after 2020, focus and difficulty China’s poverty governance will change from solving absolute to alleviating relative poverty. Analyzing studying alleviation perspective public health services is in line with current needs consolidating expanding China, it also great significance building a long-term solution mechanism for In this study, basic panel data were constructed by using five CFPS surveys 2010, 2012, 2014, 2016, 2018 matched...

At present, the dual pressure of rural labor outflow and population aging in China makes problems elderly increasingly prominent, its health problem is particularly prominent. Based on 2014 survey data (CLHLS), this paper finds that physical status has a significant positive impact their loneliness; is, with poor are more likely to feel lonely. same time, age loneliness. On contrary, gender, personality, family income intergenerational support have negative Chronic diseases such as...

Integrated Multi-satellitE Retrievals for GPM (Global Precipitation Measurement) (IMERG) is the primary high spatiotemporal resolution precipitation product of era. To assess applicability latest released IMERG_V07 in mainland China, this study systematically evaluates error characteristics from perspective different seasons, intensity, topography, and climate regions on an hourly scale. Ground-based meteorological observations are used as reference, performance improvement relative to...

Although some researchers have reported that chlorides may play an important part in the evaporation of copper during heat treatment municipal solid waste incinerators (MSWI) fly ash (1, 2), details on speciation volatile matters (secondary ash, SFA) are still lacking. In this work, we used situ X-ray absorption spectroscopy (XAS) experiments involving three types SFA, which was collected from a high-temperature tubular electric furnace by thermal incinerator at 1000, 1150, and 1250 °C. The...

China has entered a "post-poverty alleviation" era, where the achievement of sustainable livelihoods by farmers become focus. This study used Family Panel Studies (CFPS) database, which was constructed based on an analysis DFID livelihood framework, and built index system for using entropy weight method to measure weights indexes calculate index. Tobit model discuss impacts different types risk farmers. The results showed that environmental risk, chronic disease major all had significant...

By introducing network game theory, this paper analyzes the internal relationship and interaction mechanism among environmental governance, local government competition, agricultural carbon peak level. On basis of theoretical analysis, a spatial panel model is constructed using data from 30 provincial-level regions in China for empirical analysis. The research finds that governments have positive competition with respect to peak, they adopt complementary strategies, are more inclined take...

Rural family differentiation is an important perspective to analyze farmers’ behavior and poverty. Based on the data of 1673 farm households from rural field survey in 2019 Hubei Province China, this paper examines main influencing factors household poverty vulnerability sustainable livelihoods households. On basis, contribution each factor analysed using regression decomposition method. The results study show that variables have a significant impact vulnerability, net income per capita,...

Abstract A starter culture composed of P ediococcus pentosaceus , L actobacillus sakei and S taphylococcus xylosus isolated from C hinese‐fermented sausages was used to manufacture fermented sausages. The effects the on histamine accumulation, nitrite depletion, lipid oxidation quality parameters including pH water activity total volatile base nitrogen ( TVB ‐ N ), as well color texture properties, were evaluated. accumulations 0.32 8.85 mg/kg in inoculated with by a spontaneous...
