Background: Postmenopausal osteoporosis (PMOP) is a prevalent metabolic bone disorder characterized by decreased bone mineral density (BMD) and skeletal fragility, leading to increased susceptibility to fractures. The therapeutic efficacy of zoledronic acid and denosumab, two widely used agents in t...

An immersed virtual element method is developed to solve the second-order interface problems in two-dimensional space , which overcomes the problem that the constructed space cannot satisfy both the coordination and jump conditions. The key idea is to use the conforming virtual element spaces on...

As the most popular meat resource in China, pork deserves great attention of quality supervision. The quality of pork plays an important role in supporting the qualified daily life, nutrition ingestion and safety of dietary. The nondestructive detection technology is a dominant means for pork qualit...

The problem of forming the skeletons of halftone images with two-mode brightness histograms under conditions of changing contrast and noise is considered. On such histograms, one mode corresponds to the objects, and the other to the background. Thanks to this feature, images are relatively easy to b...

In Sichuan Basin with low solar radiation, the grain yield of hybrid rice was restricted by the high humidity and small diurnal temperature. The breeding and application of large panicle hybrid varieties solved the problem to a certain extent. However, the high-yielding performance of large panicle...

Whether the coating material of CA fertilizers lead to pollution of soil and crops is a question awaiting a reply. Hence, we investigated the influence on wheat growth and soil enzyme activities and on degradation of the high polymer ingredients. The results obtained were as follows. No undesirable...

It was observed by N-isotopic technique that the application of CAF (controlled availability fertilizers) might increase nitrogen utilization efficiency and recovery rate which were two times as the traditional way. Furthermore, the rate of nitrogen release coincided with the needs of crops to nitro...

Direct-seeding rice is becoming more and more popular because of its simplification, which can effectively reduce the demands of labors for rice production. However, it usually needs larger planting density to achieve high grain yields which easily leads to an oversize rice population, and hence the...

Artificial intelligence (AI), cloud computing, big data, and other technologies can not only improve the perception and connection of the railway Internet of things (RIoT) but also provide support for the intelligent analysis of data in the RIoT system. Firstly, based on the theory of smart Internet...

Coated ureas (CUs: CU1, CU2) were made of normal granular urea by coating with organic polymer layers in different thickness. the nitrogen release rate of CUs were determined in lab under different conditions, The results obtained showed that: Coated ureas were all slow-release fertilizers. The thic...

Tillering and earing is a key factor for yield formation in rice and one of remarkable features of highyield colony, characterized by effective panicles per unit area. Transplanting seedling age is an important factor that may greatly affect tillering and panicle formation. Related researches have s...

Transplanting seedling age is an important factor that may greatly affect the population quality and grain yield formation of rice. Related researches have showed that by extending the transplanting seedling ages, the tillering growth rate would slowed down; the growth duration would get shorted; pe...
