作者: AC Ludwig 摘要: There are at least three different definitions of cross polarization used in the literature. The alternative definitions are discussed with respect to several applications, and the definition which corresponds to one standard measurement practice is proposed as the best choice....
Such a general definition gives antenna engineer the freedom to choose appropriate reference polarization depe nding upon the type of the AUT and its application. Also, a few remarks are made on the Ludwig-3II definition and the reason for it's incompatibility with the H-field aperture model ...

MM cells can rely on Bruton’s tyrosine kinase (BTK) signaling to induce M2 polarization, while M2 polarized macrophages mutually upregulate CXCL13 expression in MM cells via TGFβ. With a higher level of CXCL13, enhanced formation of osteoclasts and elevated receptor activator of nuclear kappa ...
we reveal the spatial nature of sublattice symmetry and show that this assertion holds only if the periodicity of primitive unit cells agrees with that of the sublattice labeling. In cases where the periodicity does not agree, sublattice symmetry is represented as a glide reflection in energy–...

Following an ischemic injury to the brain, the induction of angiogenesis is critical to neurological recovery. The angiogenic benefits of mesenchymal stem cells (MSCs) have been attributed at least in part to the actions of extracellular vesicles (EVs) t
Light-by-light scattering (γγ→γγ) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider thanks to the large electromagnetic field strengths generated
Antigen binding by B cell receptors (BCR) on cognate B cells elicits a response that eventually leads to production of antibodies. However, it is unclear what the distribution of BCRs is on the naïve B cell and how antigen binding triggers the first s
generated by the VUV source pulse. Then, delayed population of CB2 and CB3 is induced by Landau–Zener transitions driven by the gate field. The source-gate-delay and time evolution axis origin are the same as in panel (a). In all panels, the gate-induced linear polarization is omitted....
