Sentence examples for a ulf from inspiring English sources

These coherent Pc3 wave signatures indicate that our tool can facilitate monitoring of a ULF wave event in different locations of geospace.

In this paper we examine the latter hypothesis and search for a ULF magnetic field response to the regional lightning activity, using data from the high-sensitive induction magnetometer at the station Moshiri.

Based on the AMPTE/CCE data, Cheng and Lui (1998) identified a ULF instability with a wave period of about 60 100 s (in the Pi2 range), which is excited about 2 3 min before the current disruption starts.

For those who want to prepare for the year 1 phonics screening test, this set of 40 cards containing both real and pseudo words (the latter illustrated with creative pictures that could lead to some new words being incorporated into the English language – perhaps an ulf will become one of your pupils' favorite animals, or even a vap).

We also discuss the design of a "hybrid" ULF MRI/MEG system under development in our laboratory that uses SQUID pick-up coils separately optimized for MEG and ULF MRI.

Onset in a specific ULF wave band is then defined as the initial time at which the wavelet power coefficient rises above the quite time threshold.

Induction magnetometer data from the mid-latitude station Moshiri (geomagnetic latitude 35.6°) has been examined in search of a transient ULF response to the regional lightning activity.

However, Shalimov and Bösinger (2008) proposed that relatively infrequent (∼10%), but more intense (about an order of magnitude) positive cloud-to-ground flashes CG+ can provide a necessary ULF background at large distances.

In this paper we discuss the considerations and challenges required to develop a combined ULF MRI/MEG device, including pulse sequence development, magnetic field generation, SQUID operation in an environment of pulsed pre-polarization, and optimization of pick-up coil geometries for MRI in different noise environments.

Further, it will be assumed that an incident ULF wave is the Alfven mode.

In this article, we present a ULF-MRI sequence designed for obtaining all three components of a current-density pattern without the need of sample rotations.
