Chemical observations of a polar vortex intrusion [PDF]

, 2006
An intrusion of vortex edge air into the interior of the Arctic polar vortex was observed on the 31 January 2005 flight of the NASA DC-8 aircraft. This intrusion was identified as anomalously high values of ozone by Airborne Raman Ozone, Temperature, and

Analysis and design of DC blocks

Electronics Letters, 1981
Four types of microstrip coupled line DC blocks are analysed and expressions for the theoretically possible maximum bandwidth for a given ripple are derived. A procedure for designing a DC block to meet a given set of ripple and bandwidth specifications is indicated.

Neutral-point-clamped hybrid multilevel converter with DC fault blocking capability for medium-voltage DC transmission

Journal of Modern Power Systems and Clean Energy, 2017
This paper proposes a novel hybrid multilevel converter with DC fault-blocking capability, i.e., the neutral-point clamped hybrid multilevel converter (NHMC).

Excess phase in microstrip DC blocks

Electronics Letters, 1984
The letter gives details of excess phase calculations and measurements on microstrip DC breaks. Published microstrip discontinuity data has been used to develop an equivalent circuit which yields very good agreement between experimental and theoretical phase results over the frequency range 8 to 12 GHz.

Transient overvoltage suppression measures for new energy high penetration system at the sending end under bipolar blocking fault

电力工程技术
Aiming at the transient overvoltage problem in the new energy high-penetration area of the feeder due to DC bipolar blocking fault, a converter bus reactive power allocation capacity optimization scheme is proposed with the constraint that the transient ...

SARS-CoV-2 suppresses TLR4-induced immunity by dendritic cells via C-type lectin receptor DC-SIGN.

PLoS Pathogens, 2023
SARS-CoV-2 causes COVID-19, an infectious disease with symptoms ranging from a mild cold to severe pneumonia, inflammation, and even death. Although strong inflammatory responses are a major factor in causing morbidity and mortality, superinfections with

Operation analysis of thyristor based front-to-front active-forced-commutated bridge DC transformer in LCC and VSC hybrid HVDC networks [PDF]

, 2017
The active-forced-commutated (AFC) bridge employs a symmetrical thyristor-bridge with auxiliary self-commutated full-bridge chain-link (FB-CL) circuit to assist its soft transition and forced commutation.
