A Doherty amplifier is described in which odd harmonics from the class-C peaking amplifier flow to the main amplifier to achieve class-F operation, without the need for complicated space consuming harmonic control circuits. The measured efficiency ex

This article introduces a gate bias control scheme for Doherty amplifiers, based on the measured gate-voltage to drain-current transfer characteristics of the FETs used, and their ideal fundamental output currents. An amplifier was realized at 800 MH

A Doherty amplifier's theoretical gain and efficiency characteristics significantly exceed those achieved by practical simulations and implementations. Analysis and simulation demonstrates that the FET gate voltage to drain current transfer character

The Santee–Cooper system in South Carolina, USA, is a complex of reservoirs, rivers, and canals. The endangered shortnose sturgeon Acipenser brevirostrum inhabits the rivers below the reservoirs and has also occasionally been reported anecdotally i

An experimental stock enhancement program was conducted in Port Royal Sound estuary, South Carolina, in which cultured juvenile red drum (Sciaenops ocellatus, 2–3 cm TL, ∼40 days old) were released into a system of shallow tidal creeks that flow

The localization and identification of sounds in background noise are such important auditory processing skills that a significant amount of incompetency may lead to various confusions and learning delays. Through a partnership with James Madison Uni

A karyotype analysis by several staining techniques was carried out on triplicate samples of the shortnose sturgeon, Acipenser brevirostrum . The chromosome number was found to be 2n = 372 ± 6. A representative karyotype of 374 chromosomes was compo

To gauge the impact of screening mammography and the results of clinical trials on the pattern of primary surgical care of early breast cancer, tumor registry data from the Charleston Area Medical Center for 1980-81 was compared to tumor registry dat

We analysed the early viremia and clinical tests in 82 patients with epidemic hemorrhagic fever (EHF). The results showed that the changes in viremia and clinical tests are related to the severity of the disease and prognosis. Higher concentrations o

To determine if rhesus monkeys (Macaca mulatta) could serve as a model for studying the role of the contact system in the pathophysiology of human infections, we compared structural, kinetic, and functional characteristics of plasma prekallikrein and
