Magnetohydrodynamic modes in a periodic magnetic steady state medium [PDF]

open access: yesAstronomy & Astrophysics, 2006
The spatial structuring of solar and space plasmas is known to have a dispersive effect on waves. Many solar features possess a periodic structure with structures having alternating properties. Here the effect of periodic alternation of magnetic slabs on wave propagation is studied when the equilibrium has a steady motion (in line with observations ...

Quantum Trajectory Analysis of the Two-Mode Three-Level Atom Microlaser

open access: yes, 2011
We consider a single atom laser (microlaser) operating on three-level atoms interacting with a two-mode cavity. The quantum statistical properties of the cavity field at steady state are investigated by the quantum trajectory method which is a Monte ...

Stability of pulse-like earthquake ruptures [PDF]

open access: yes, 2019
Pulse-like ruptures arise spontaneously in many elastodynamic rupture simulations and seem to be the dominant rupture mode along crustal faults. Pulse-like ruptures propagating under steady-state conditions can be efficiently analysed theoretically, but ...

Moisture Mode Oscillations in Steady‐State Weak Temperature Gradient Simulations

open access: yesJournal of Advances in Modeling Earth Systems
Weak Temperature Gradient modeling using a small cloud‐resolving model admits multiple equilibria depending upon the initial model conditions. There were thought to be two equilibrium states, a moist precipitating state and a dry non‐precipitating state.

Disturbance observer‐based sliding mode control for dynamic performance enhancement and current‐sensorless of buck/boost converter

open access: yesIET Power Electronics, 2021
Bidirectional DC‐DC converters are widely used in electric vehicle charger, where excellent steady‐state and dynamic performances are crucial. However, those two performances are easily affected by external disturbances and parameter uncertainties.

Quantum cooling and squeezing of a levitating nanosphere via time-continuous measurements [PDF]

open access: yes, 2015
With the purpose of controlling the steady state of a dielectric nanosphere levitated within an optical cavity, we study its conditional dynamics under simultaneous sideband cooling and additional time-continuous measurement of either the output cavity ...

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Vibration testing and analysis using holography [PDF]

open access: yes, 1971
Time average holography is useful in recording steady state vibrational mode patterns. Phase relationships under steady state conditions are measured with real time holography and special phase shifting techniques.
