The positive phase of the PNA pattern is associated with above-average temperatures over western Canada and the extreme western United States, and below-average temperatures across the south-central and southeastern US . The PNA tends to have little impact on surface temperature variability over North America during summer.

The US Food and Drug Administration ( FDA ) and European Medicines Agency ( EMA ) have both indicated they will not issue approval for pridopidine to be used in human patients on the basis of the MermaiHD and HART trials, and a further, positive phase 3 trial is required for approval.

Wang " et al . " suggest that in addition to anomalous winds driving sea ice out of the Arctic through the Fram Strait, the positive phase of the Arctic dipole anomalies may also increase the flow of relatively warm waters from the North Pacific through the Bering Strait into the Arctic Ocean.

It uses the principle that the positive phase angle of an inductive impedance can be compensated by the negative phase angle of a capacitive impedance when put in the opposite arm and the circuit is at resonance; i . e ., no potential difference across the detector and hence no current flowing through it.

At frequencies below resonance, the crystal is capacitive and the " gain " of the negative feedback branch has a negative phase shift . At frequencies above resonance, the crystal is inductive and the " gain " of the negative feedback branch has a positive phase shift . The phase shift goes through zero at the resonant frequency.

We have a good opportunity now to initiate a more positive phase in the trade and economic relations between the U . S . and Japan, one in which the tone becomes more cooperative and more oriented towards the common goal of building a world economy in which our two countries are not pictured as antagonists but as close partners,
