Steady-state Fano coherences in a V-type system driven by polarized incoherent light

open access: yesPhysical Review Research, 2021
We explore the properties of steady-state noise-induced (Fano) coherences generated in a three-level V-system continuously pumped by polarized incoherent light in the absence of coherent driving.

Analysis of Impulse Devices of Phase Locking with Charge Pumping

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2004
A mathematical model of impulse devices of phase locking with charge pumping has been developed in state space. The paper proposes an algorithm of modeling transient processes. An analytical expression for parasitic deviation of frequency in steady-state

Simultaneous estimation of reference temperature and heat transfer coefficient in transient film coo

open access: yesJournal of Thermal Engineering, 2023
This paper aims to simultaneously estimate the reference temperature and heat transfer coefficient in film cooling situations from transient temperature measurements. The exist-ing steady-state technique is a tedious process and employs distinct boundary

balanced-steady-state-2.pdf

open access: yes, 2016
Balanced steady-state free precession (bSSFP) is a magnetic resonance imaging (MRI) technique where magnetic spins in the body are repeatedly excited over a short period of time to create a steady-state MRI signal.

A Situational Assessment of the Diagnostic Landscape and Organizational Readiness to Implement Next‐Generation Sequencing at Two Childhood Cancer Treatment Centers in Ghana

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Next‐generation sequencing (NGS) has emerged as a promising approach to improve diagnostic accuracy, but its feasibility in low‐ and middle‐income countries remains unknown. This study characterized the diagnostic landscape and assessed organizational readiness for NGS implementation at two childhood cancer treatment centers in Accra ...

Grid-connection damping strategy for grid-forming VSG based on angular frequency lead-lag feedforward compensation

open access: yesInternational Journal of Electrical Power & Energy Systems
The primary frequency modulation coefficient of the grid-forming virtual synchronous generator (GFVSG) is coupled with the virtual damping coefficient, which leads to the problem that it is difficult to take into account both the dynamic oscillation and ...

Effects of Sound-Pressure Change on the 40 Hz Auditory Steady-State Response and Change-Related Cerebral Response

open access: yesBrain Sciences, 2019
The auditory steady-state response (ASSR) elicited by a periodic sound stimulus is a neural oscillation recorded by magnetoencephalography (MEG), which is phase-locked to the repeated sound stimuli.
