Influence maximization in social networks is of great importance for marketing new products. Signed with both positive (friends) and negative (foes) relationships pose challenges opportunities, since the influence can be leveraged to promote information propagation. In this paper, we study problem advertisement recommendation signed networks. We propose a framework characterize propagation process networks, which models dynamics individuals' beliefs attitudes towards based on recommendations...
Monitoring the subsidence at different periods in high underground water level coal mine areas can provide a data basis for land reclamation. For purpose of monitoring I working face located Guotun Coal Mine, 22 Sentinel-1 images were processed by using differential interferometric synthetic aperture radar (D-InSAR). After dividing periods, characteristics and accuracy explored. The results showed that: (1) formation single-gradient funnel is an important sign to identify active period. (2)...
CdS thin films were prepared by chemical-bath deposition (CBD) from a bath containing thiourea, acetic cadmium, ammonia and ammonium acetate in aqueous solution onto glass substrates at 80°C with stirring. The influence of pH value on the surface morphology optical properties was investigated. Step height measurement instrument, scanning electron microscopy (SEM), X-ray diffraction (XRD), spectrophotometer digital four-point probe resistance used to characterize their thickness, morphology,...
Carbon footprint is a new method to measure carbon emissions, and the ecological compensation criterion can be determined according regional carrying capacity. The spatial temporal patterns of were studied among 11 cities in Jiangxi Province using footprint, capacity surplus/deficit models. Our results found that showed rapid growth trend from 2000 2013, with an average annual rate 8.7%. always remained surplus, but net surplus amount decreased 2013. Among cities, Nanchang Jiujiang made...
The effects of simulated acid rain and aluminum (Al) addition on growth photosynthesis physiology tea plants (Camellia sinensis L.) were studied with seedlings in a hydroculture experiment. Results showed that the plant, chlorophyll content, (Pn) leaves better treatments suitable Al (10 mg/L and/or 20 mg/L) than without higher (30 mg/L). plant increased increasing acidity rain, while more content Pn at treatment pH 4.0 5.0 3.0 solutions. best combined (10~20 moderate (pH 4.0), slowest 30...
In order to solve the current bee products quality and safety issues, this paper presents traceability system for based on intelligent business. This uses state-of-the-art technologies, such as ASP.NET, CDMA, GPS, XML, data collection barcode technology. Distinctive apiculture log an information carrier plays a key role in system. It saves from Android terminal is uploaded Access database server. The web client displays analysis results enterprise management personnel view feedback. To...
A 25-year-old tea plantation in a typical red soil region was selected for an situ simulated acid rain experiment treated by pH 4.5, 3.5, 2.5 and water (control, CK). Roots with different functions, leaves twigs ages were collected to measure nitrogen (N) phosphorus (P) contents the third year after treatment. The N/P sensitivity coefficient of plant organs also calculated. results indicated that increase intensity, pH, NO3--N available P decreased, while absorption root N content increased....
Winter wheat and summer maize rotation is the main cropping pattern in North China Plain (NCP). There are still problems with farmers’ production modes, including shallow tillage layers, single application of chemical fertilizer causing plow bottom layer thickening soil pH decrease. A two-factor location experiment was conducted to investigate effects different fertilization patterns on physical properties, organic carbon (SOC), nitrogen-use efficiency, crop yield wheat–maize systems during...
<title>Abstract</title> The high‑groundwater‑level coal mining areas have a long history of and are mainly located in east-central region China. Subsidence caused by has several different periods. However, the subsidence change regularity each periods remains unclear. This study aimed at revealing Juye area was selected for study, which Heze City, Shandong Province, Firstly, 54 Sentinel-1A radar satellite images from August 2018 to July 2020 were acquired this research. “two-track method”...
In order to guarantee the safety of bee products, combining with other countries’ experiences and characteristics our own industry, this paper puts forward products quality tracking system based on Android smartphone. The Fig.1 displays its general framework. Fig.1, links farmers cooperative enterprise so that it forms a management model reach goal realize tracking. system, information submitted server step by step, through way we could get all data their sources. Also analyzes some key...
To maximize the scope and effect of information propagation in social networks, we need to explore both its intrinsic properties spread theories elaborately. The key challenge is how find individuals who are most powerful a specific thing given network topology. Due high time complexity, classical solution, i.e., Greedy algorithm, can not be applied solve this problem, especially for large-scale network. In paper, taking centrality similarity into account, define novel viral marketing model...
