Contrasting arbuscular mycorrhizal communities colonizing different host plants show a similar response to a soil phosphorus concentration gradient [PDF]

, 2013
High soil phosphorus (P) concentration is frequently shown to reduce root colonization by arbuscular mycorrhizal (AM) fungi, but the influence of P on the diversity of colonizing AM fungi is uncertain.

Behavioral Modeling of GaN Doherty Power Amplifiers Using Memoryless Polar Domain Functions and Deep Neural Networks

IEEE Access, 2020
In this paper, novel Doherty Power Amplifier (DPA) models are presented. The motivation behind the proposed models is to accurately predict static nonlinearities in the compression regions of the carrier and peaking amplifiers.

A Fast AM/AM and AM/PM Characterization Technique

, 2003
In this paper a novel AM/AM and AM/PM power amplifier characterization technique is presented, exploiting signals interference properties. Key features of the proposed measurement technique are the simplicity, requiring basic scalar power measurements only, and the low cost of the utilized set-up; moreover, it allows a power amplifier distortion ...

Photometry and dynamics of the minor mergers AM\,1228-260 and AM\,2058-381

, 2015
We investigate interaction effects on the dynamics and morphology of the galaxy pairs AM\,2058-381 and AM\,1228-260. This work is based on $r'$ images and long-slit spectra obtained with the Gemini Multi-Object Spectrograph at the Gemini South Telescope.
