An oscillation suppression strategy for hybrid DC systems based on virtual resistance

open access: yesZhejiang dianli
Hybrid DC transmission systems are prone to DC current oscillations as the parameters of constant DC current controller increase, an oscillation suppression strategy based on virtual resistance is proposed.

Spatiotemporal oscillation of an ion beam extracted from a potential-oscillating plasma source

open access: yesNew Journal of Physics, 2019
A radiofrequency oscillation is successfully superimposed on a plasma potential of a filamented source plasma in an ion beam source while maintaining a constant plasma density, in order to investigate effects of oscillating source plasma potential on an ...

Dynamics of Fluid Vesicles in Oscillatory Shear Flow

open access: yes, 2009
The dynamics of fluid vesicles in oscillatory shear flow was studied using differential equations of two variables: the Taylor deformation parameter and inclination angle $\theta$. In a steady shear flow with a low viscosity $\eta_{\rm {in}}$ of internal

Homogeneous Time Constants Promote Oscillations in Negative Feedback Loops [PDF]

open access: yesACS Synthetic Biology, 2018
Biological oscillators are present in nearly all self-regulating systems, from individual cells to entire organisms. In any oscillator structure, a negative feedback loop is necessary, but not sufficient to guarantee the emergence of periodic behaviors. The likelihood of oscillations can be improved by careful tuning of the system time constants and by

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

Dually-mode-locked ND: YAG laser [PDF]

open access: yes, 1974
Mode-locking is stabilized effectively by conventional loss-modulator and phase-modulator, mode-locking elements placed in laser cavity in optical series with one another.

Transverse Ising Chain under Periodic Instantaneous Quenches: Dynamical Many-Body Freezing and Emergence of Solitary Oscillation

open access: yes, 2012
We study the real-time dynamics of a quantum Ising chain driven periodically by instantaneous quenches of the transverse field (the transverse field varying as rectangular wave symmetric about zero).

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Critical Oscillation Constant for Euler Type Half-Linear Differential Equation Having Multi-Different Periodic Coefficients

open access: yesInternational Journal of Differential Equations, 2017
We compute explicitly the oscillation constant for Euler type half-linear second-order differential equation having multi-different periodic coefficients.

Constant Flow-Driven Microfluidic Oscillator for Different Duty Cycles [PDF]

open access: yesAnalytical Chemistry, 2011
This paper presents microfluidic devices that autonomously convert two constant flow inputs into an alternating oscillatory flow output. We accomplish this hardware embedded self-control programming using normally closed membrane valves that have an inlet, an outlet, and a membrane-pressurization chamber connected to a third terminal.
