When subjected to shear loading condition,a steel rock bolt will become bent in the field close to the loading point in situ.The bolt is deformed as the joint displacement increases,which can mobilize a normal load an...
We examined dietary quality and weight loss among adults who drank flavored milk sweetened with either high fructose corn syrup (HFCS) or sucrose at average population consumption levels of fructose. This was a blinde...
It is fundamental that changes in coal reservoir permeability are researched, in particular, the accurate determination of variations in the coal matrix caused by CO2 replacing CH4 at different gas saturation conditio...
Adenomatoid odontogenic tumor is an unusual benign neoplasm which shares clinical and radiographic characteristics with odontogenic cystic lesions denoting a distinct behavior. This paper reports a case of a 12-year-o...

Hydrocarbon resources in low-permeability sandstones are very abundant and are extensively distributed. Low-permeability reservoirs show several unique characteristics, including lack of a definite trap boundary or ca...
Using the technique of integral within an ordered product (IWOP) of operators we show that the wavelet transform can be recasted to a matrix element of squeezing-displacing operator between the mother wavelet state ve...
A type of special two-mode squeezed coherent state is constructed which is a characteristic of squeezing and displacing related. The new states take simpler and neater form than the usual two-mode squeezed coherent st...
