Achievable directive antenna gain measurements and modeling for 60 GHz indoor links [PDF]
Scientific ReportsHighly directive antennas may be a key component in millimeter wave links to offset their inherently high path losses. In cluttered scenarios such as Non-Line-Of-Sight (NLOS) indoor settings, antenna gain is degraded by the interaction of the channel ...

Nonlinear anti-directional couplers with gain and loss [PDF]
Optics Letters, 2019 Following the concept of $\mathcal{PT}$-symmetric couplers, we propose a linearly coupled system of nonlinear waveguides, made of positive- and negative-index materials, which carry, respectively, gain and loss. We report novel bi- and multi-stability states pertaining to transmitted and reflective intensities, which are controlled by the ratio of the ...

DIRECT RESPONSE TO SELECTION FOR POSTWEANING GAIN IN THE RAT [PDF]
Genetics, 1975 ABSTRACT The effectiveness of selection for 3–9-week gain was examined in a population of rats with a history of past selection for high 3–9-week gain. Lines were selected for high (U line) and low (D line) 3–9-week gain with two replicates of each line.
