The SW was characterized by recurrent fast speed streams and associated high densities, especially for 2006 2008, while the average speed reached the lowest values in 2009.
Recurrent high speed solar wind streams from coronal holes on the Sun are more frequent and Geoeffective during the declining phase of solar cycle which interact with the ambient solar wind leading the formation of Corotating Interaction Regions (CIRs) in the interplanetary medium.
In comparison, strong and recurrent high-speed streams from coronal holes remained active during most of the period studied in this paper.
Although there were recurrent high-speed streams emanated from the coronal holes around the solar minimum of cycle 22, their effect on geomagnetic disturbances seems to be weak during this period.
Facebook says it has achieved a small bump in accuracy at nine times the speed of traditional recurrent network models.
In this paper, a new design formula is presented to accelerate the convergence speed of a recurrent neural network, and applied to time-varying matrix square root finding in real time.
In addition to the Doppler-shifted 10-day normal mode oscillation origin, the 8- to 9-day waves have also been reported to be related with the quasi-periodic variations of solar wind high-speed streams and recurrent geomagnetic activity, especially for the year 2005 (Thayer et al. 2008).
The recurrent theme in his response was speed: "rapid" moves to reassure shareholders that a new strategy was unfolding; "fairly rapid" steps to shed noncore businesses and, most of all, a quicker-than-expected deal last month to disentangle the cross-holdings of Anglo American and De Beers, the diamond colossus that is Anglo's sister company in the Oppenheimer family empire.
There is little information in the literature to inform such an assumption, but we may have slightly overestimated the speed of reduction of recurrent respiratory papillomatoses given that they can occur in young children some years after birth.
It may happen in a short time span as the outbreak of H7N9 is more and more recurrent, which implies that H7N9 evolution is speeding up.
