We adopted definitions of LTNP/VC from previous studies and the actual state of HIV-1 infections and patient follow-up policies in Henan to establish a study definition of LTNP/VC. All patients were: 1) Being diagnosed as HIV-1 infection before December 31, 2005; 2) Antiretroviral-naïve...
The realizations are based on a model previously developed that accounts for the enlarged transport matrix at supercritical conditions ( Soret and Dufour effects), for real gas equations of state, and for variable Schmidt and Prandtl numbers. This model is exercised for two very different sets of...
Therefore, the normally off characteristics of MOSFETs with an inversion channel are more advantageous than the characteristics of devices with an accumulation channel or devices that use the bulk as a channel when such devices have conduction carrier supplied by the same semiconductor type at their ...
In the vertical direction, during the Chang 73 sedimentation period, the lake surface area and water depth reached their maxima, and S and Mh lithofacies developed, which were conducive to the formation of high-quality hydrocarbon source rocks for tight oil. During the Chang 72-Chang 71 ...
