However, the structure of the Berry curvature vector field carries additional information that is closely related to the band structure. Namely, based on our observations, the flow of the Berry curvature is tangent to the manifold of maximal hybridization (line in the 1D case and surface in the...
This paper describes a novel method for regional characterization of three-dimensional vector fields using a pattern matching approach. Given a three-dimensional vector field, the goal is to automatically locate, identify, and visualize a selected set of classes of structures or features. Rather than...
The vector magnetic field is determined from the Stokes profiles of the magnetically sensitive lines Fe I 630.15 and 630.25 nm, and Doppler velocities and intensities are measured in several lines including the weak C I 538.03 nm line, formed in the deepest layers of the atmosphere. The ...
PIV measurements were made above the free ends of the bodies in a vertical plane aligned with the flow centreline. The present PIV results provide insight into the effects of aspect ratio and body shape on the instantaneous flow field. The recirculation zone under the separated shear layer is ...
by grid extensions [35] and inclusion of a model for the sheath for glancing field line angles [43]. Sheath physics in general plays a significant role for the power balance. Usually fixed so called sheath heat transmission factors γe,i are used to impose heat fluxes at the target ...
The black dahsed line shows the quenching distance from the experiment, the mean quenching distance from the instantaneous temperature data \(\overline{d(t)}\), and the quenching distance when applying the temperature marker to the mean temperature field \(d({\bar{t}})\) from the two ...

Streamline plots show curves that are tangent everywhere to an instantaneous vector field. For this reason, they are often used to visualize fluid flow. While they are best known for their wavy shapes, significant care and intention can go into the creation of good streamline plots. We’ll ret...
angle, down to an elliptical anastomosis with a major axis of 30 mm, corresponding to an anastomosis angle of 13°. The major axis was defined as the maximum length of a line bisecting the ellipse formed when the cylindrical, conical graft intersected the cylindrical vein. The 7 mm, 8 mm...
In the rabbit-ui each line is in fact a channel - and when pushing arbitrary values around (via the left-side channel panel) you are putting the value "on the line" as opposed to "in a block", which is an important distinction in large more complex flows views and optional key ...
