The signal S is a function of θ. Therefore, DCE MRI data which is acquired before, during and after intravenous injection of contrast agent show dependence on FA. B 1 field inhomogeneity results in variation of nominal FA and hence in the signal intensity time curve (S(t)) of DCE-...
Besides, loss of function of some DHN genes can also decrease the cold stress tolerance of transgenic plants. For exam- ple, silencing of either CaDHN1 or CaDHN3 in pepper resulted in obviously lower resistance to cold stress com- pared with the control (Chen et al. 2015; Jing et ...
