An approach to calculate the accurate ray paths and traveltimes in multi-layered VTI media (transversely isotropic media with a vertical symmetry axis) is proposed. The expressions of phase velocity,
In this paper, we firstly use finite element method (FEM) with Burgers model to simulate the postseismic viscoe-lastic relaxation taking 1960 Chile earthquake as an example. The postseismic deformatio
Illustration All the data in this catalog are chosen from the ″Preliminary Seismological Report of Chi-nese Seismic Stations″ (Its abbreviation is ″Monthly Report″). The catalog includes the events of
Nitrogen, phosphorous and potassium are essential nutrients for plant growth and development. However, their contents in soils are limited so that crop production needs to invest a lot for fertilizer
Phosphorus is one of the macronutrients essential for plant growth and development. Many soils around the world are deficient in phosphate (Pi) which is the form of phosphorus that plants can absorb a
During leaf organogenesis, a critical step for normal leaf primordium initiation is the repression of the class 1 KNOTTED1- like homeobox (KNOX) genes. After leaf primordia are formed, they must estab
Ligularia virgaurea is a perennial herb that is widely distributed in the alpine meadow on the eastern Qinghai-Tibet plateau. We investigated the patterns of growth and reproduction of L. virgaurea un
Theory predicts that cosexual plants should adjust their resource investment in male and female functions according to their size if female and male fitness are differentially affected by size. Howeve
Dissimilatory Fe(Ⅲ) reduction is a universal process with irreplaceable biological and environmental importance in anoxic environments. Our knowledge about Fe(Ⅲ) reduction predominantly comes from pur
Continuous observation data collected over the whole year of 2004 on a cropland surface in Tongyu, a semi-arid area of northeastern China (44°25′N, 122°52′E), have been used to investigate the variati
