An Active Damping Control Strategy for LCL Grid-Connected Inverter Based on Virtual Resistor
Kongzhi Yu Xinxi Jishu, 2018 For the resonance of LCL grid-connected inverter, traditional solutions are damping as filter capacitor and resistance in series , filter capacitor current feedback, filter capacitor voltage feedback and so on, but these approaches lead to increased ...

Arthritis Care &Research, EarlyView.We report the national burden of dermatopolymyositis mortality over the past quarter century using the US national vital statistics data. Age‐standardized mortality rates for dermatopolymyositis decreased at an annual rate of 3.8% each year, which was higher than the annual percent decrease for deaths from all other causes.

An optimal design method of the resonant-free C-type filter
电力工程技术Configuring a reactive power compensation capacitors as a resonant-free C-type filter is a common method to suppress reactive power compensation capacitors resonance. It can also be used to reduce the amplification of harmonic voltage caused by resonance

The Reaction 7Li(pi+,pi-)7B and its Implications for 7B
, 1998 The reaction 7Li(pi+,pi-)7B has been measured at incident pion energies of 30-90 MeV. 7Li constitutes the lightest target nucleus, where the pionic charge exchange may proceed as a binary reaction to a discrete final state.

Arthritis Care &Research, EarlyView.Objective We aimed to validate the Pediatric Arthritis Ultrasound Scoring System (PAUSS) for upper extremity joints in children with juvenile idiopathic arthritis (JIA). Methods Children with JIA were evaluated for elbow, wrist, or finger arthritis by clinical examination (CE) and musculoskeletal ultrasound (MSUS) with images scored according to the ...

Photonic ring resonator filters for astronomical OH suppression
Optics Express, 2017 Ring resonators provide a means of filtering specific wavelengths from a waveguide, and optionally dropping the filtered wavelengths into a second waveguide. Both of these features are potentially useful for astronomical instruments. In this paper we focus on their use as notch filters to remove the signal from atmospheric OH emission lines from ...
