curve from the Baltic and Ukrainian Shields can be matched with that from Africa and North America such that there was crustal continuity prior to 1000 Ma with the Gothide and Grenville mobile belts in great-circle alignment. The limited palaeomagnetic data from the Siberian Shield do not allow...

Each magnet was secured in a machined aluminum frame (Xometry, North Bethesda, MD). Two frame styles were designed, the center style holds 32 magnets arranged in 4 rows of 8, and the end style holds 48 magnets in 6 rows of 8. In total, 4 end and 8 center frames were machined. Cube...
CI was derived from observations of coronal intensity at the green coronal line (5303 Å) by ground-based coronagraphs, and coronal intensity was measured daily at a height of 40” above the solar limb at 72 evenly spaced points on a circle, which start from 90∘ (the north pole) and...
CameronEnglmanMD, ...FrancescoGigantiMD, PhD, inRadiologic Clinics of North America, 2024 Multiparametric magnetic resonance (MR) imaging has had an expanding role in active surveillance (AS) forprostate cancer. It can improve the accuracy ofprostate biopsies, assist in patient selection, and help...

The Earth's magnetic field does not align perfectly with the axis of rotation, which is why "true north" differs from "magnetic north." In the Northern Hemisphere, this disparity in the modern field is driven by regions of high geomagnetic intensity that are centered beneath North America and...
