Augmented Twin-Nonlinear Two-Box Behavioral Models for Multicarrier LTE Power Amplifiers
The Scientific World Journal, 2014 A novel class of behavioral models is proposed for LTE-driven Doherty power amplifiers with strong memory effects. The proposed models, labeled augmented twin-nonlinear two-box models, are built by cascading a highly nonlinear memoryless function with a ...

Two-Port Network Theory-Based Design Method for Broadband Class J Doherty Amplifiers
IEEE Access, 2019 This paper proposes a new methodology for designing wideband Class J Doherty power amplifiers (DPAs). The paper begins by presenting a network analysis that leads to a set of design equations to govern the synthesis of the combiner network parameters ...

Corporate Political Ideology and Environmental Strategy: Evidence From US Toxic Releases
Business Strategy and the Environment, EarlyView.ABSTRACT This paper examines whether corporate political ideology shapes firms' environmental strategy and realized environmental performance. Using US political donation data matched to facility‐level toxic releases from the Toxics Release Inventory from 2000 to 2014, we measure corporate ideology by the share of firm and PAC contributions directed to

Parasitoid insects unveil complex patterns of functional change across elevational bands
Ecography, EarlyView.Climate change is rapidly reshaping how insects interact with their environment, potentially disrupting ecosystem complexity and essential functioning. While functional homogenisation has been extensively investigated for charismatic insect taxa, particularly pollinators, the response of parasitoids remains largely overlooked.
