We can have a single scalar quantity, such as the weight of a person. We can have a vector quantity, such as the direction in which that person is traveling. Tensors are higher-order quantities that describe both direction and shear forces, such as occur in materials that are being ...
We consider spin and pseudospin symmetry limits of Dirac equation in the presence of scalar, vector and tensor generalized Cornell interaction and report the solutions via the quasi-exact analytical ansatz approach.doi:10.1007/s00601-015-1033-5S....

This can be interpreted as the fact that the shear viscosity is captured by gravitational interaction terms (actually, the two-point correlation function of transverse gravitons), so that the higher-order scalar terms do not affect this quantity. Generically, one expects that the introduction of ...

The quantity 𝑆𝐵𝐻SBH is non-decreasing. This philosophy of replacing the gravitational coupling with the effective gravitational coupling that would appear if one were to rewrite the field equations of the theory as effective Einstein equations and read scalar field (or, in 𝑓(𝑅)f(R)...
The quantity P/2 coincides with the Gaussian curvature K of the surface: (92.12)P2=K=1ϱ1ϱ2 where the ϱ1, ϱ2 are the principal radii of curvature of the surface at the particular point (remember that ϱ1 and ϱ2 are assumed to have the same sign if the corresponding cen...
Scalar data are prevalent in biomedical simulation and imaging. In biomedical computing, scalar fields represent a quantity associated with a single (scalar) number, such as voltage, temperature, the magnitude of velocity. Scalar fields are among the most common datasets in scientific visualization, ...
