The term 'hospital' in its title suggests that it is only valid in such a setting but many studies conducted throughout the world have confirmed that it is valid when used in community settings and primary care medical practice.
It is only valid for u′/U ≪ 1, which is not always the case.
However, it is only valid in a steady state of AC voltage condition.
It is only valid for straight lines and cannot be used in curves.
Moreover, it is only valid if the data are independents and there is no autocorrelation or it is negative.
Similar functional relationship could be established between retention time and Ri, and it is only valid for canyons with one-vortex flow regime.
One well-known case of this noncentral χ noise model is the Rician model, but it is only valid in the case of single-channel acquisition.
It must be used for time steps larger or so than an electron cyclotron period, it is only valid for an electron plasma beta βe<1.
However, such a calibration would be only of limited use since it is only valid for the type of spheres the calibration was performed with.
Teller has been criticized for drawing unduly far-reaching ontological conclusions from one particular representation, in particular since the Fock space representation cannot be appropriate in general because it is only valid for free particles (see, e.g., Fraser 2008).
This method is not considered as a very reliable and accurate evaluation method due to several reasons including N_{text{MV}} = 6 times sqrt {(a_{text{XP95}}^{{W_{text{d}} }} )^{2} + (a_{text{YP95}}^{{W_{text{d}} }} )^{2} + (a_{text{ZP95}}^{{W_{text{d}} }} )^{2} } It is only valid for straight lines and cannot be used in curves.
