BACKGROUND: Premature atrial contractions (PACs) are independently associated with atrial fibrillation, stroke, and heart failure, yet no pharmacological therapy is approved for PAC suppression.

Announced data from cohort 4 of soquelitinib atopic dermatitis Phase 1 trial demonstrating positive safety and efficacy results, including in patients who have received prior systemic therapy ...

With not enough spectrum to go around to distribute the current load of programming, terrestrial IP, Ku-band weighed as distribution alternatives as well as 5G wireless and low earth orbit satellite.

Abstract: The symmetrical phase-shift modulation of the three-to-two-level neutral-point-clamped dual-active-bridge (3/2LNPC-DAB) DC-DC converter has more controllable control variables than the ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

In radio communications, one way to generate single sideband (SSB) signals is to make a double sideband signal by feeding a carrier and a modulation signal into a balanced modulator to create a double ...

Abstract: Utilizing periodic phase modulation (PPM) can shift the echo spectrum, affecting matched filtering (MF) processing, leading to time delay shift or amplitude attenuation. The prior works on ...

In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
