Statistical Modeling of Ultrawideband Body-Centric Wireless Channels Considering Room Volume by Miyuki Hirose, Hironobu Yamamoto, Takehiko Kobayashi

“…A measured delay profile can be divided into two domains; in the first domain (0<t≤4 ns) there is either a direct (for line of sight) or diffracted (for nonline of sight) wave which is dependent on the propagation distance along the perimeter of the body, but essentially unrelated to room volume, and the second domain (t>4 ns) has multipath components that are dominant and dependent on room volume. …”

The Optical Extinction Law Depends on Magnetic Field Orientation: The RV–ψ Relation by Brandon S. Hensley

“…We demonstrate that the measured total and polarized extinction curves of the diffuse Galactic interstellar medium imply R _V varies from 3.21 when the magnetic field is along the line of sight ( ψ  = 0) to R _V  = 3.05 when in the plane of the sky ( ψ  = 90°). …”

Register-Based Subject Omission in English and its Implication for the Syntax of Adjuncts by Liliane Haegeman

“…It is proposed that the observed argument/adjunct asymmetry observed in relation to subject omission comes about due to the fact that what at first sight appear to be sentence-initial adjuncts are in fact inserted in a structural position below the canonical subject position which hosts the deleted subject. …”
