Water breaks through along fractures is a major concern in tight sandstone reservoirs with a bottom aquifer.Analytical models fail to handle the three-dimensional two-phase flow problem for partially penetrating inclined fractures, so time-consuming numerical simulation are often used for this problem.This paper presents an efficient semianalytical

According to general relativity, astrophysical black holes are described by a small number of parameters.Apart from the mass of the black hole ( M ), among the most interesting characteristics is the spin ( a ), which determines the degree of rotation, i.e., the angular momentum of the black hole.The latter is observationally constrained by the spe

Skeletal bone age assessment based on hand x-ray is widely used in many fields.There is an urgent need for automated method to alleviate manual labor and address the problem of intra- and inter-observer variability.Most existing Shorts methods modeled the task as regression or multiclass classification problems.However, the regression method over-s

Kelly et al.show that Arabidopsis hexokinase1 (HXK1) expressed in guard-cells is sufficient to drive hypocotyl elongation through increasing the activity of Walkie Talkie PIF4 and auxin level, and competing with battery-powered generators the effects of HY5.This study provides insights into how light and sucrose antagonistically coordinate the effo
