Homogeneous label-free electrochemiluminescence biosensor based on double-driven amplification and magnetic graphene platform

open access: yesBiosensors and Bioelectronics: X, 2022
Traditional DNA-based electrochemiluminescence (ECL) biosensors generally require a laborious and time-consuming process of electrode modification. Although immobilization-free homogeneous electrochemical approaches have been proposed, the problems of ...

Active Control of Laminar Separation: Simulations, Wind Tunnel, and Free-Flight Experiments

open access: yesAerospace, 2018
When a laminar boundary layer is subjected to an adverse pressure gradient, laminar separation bubbles can occur. At low Reynolds numbers, the bubble size can be substantial, and the aerodynamic performance can be reduced considerably. At higher Reynolds

Synergistic removal of NO and chlorinated organics on CeO2-based catalysts

open access: yesEnvironmental Functional Materials, 2023
In recent years, with increasingly scarce land resources, incineration technology has gradually become the mainstream disposal method of household hazardous waste. The exhaust gas of incineration contains both NOx and chlorine-containing volatile organic

INFLUENCE OF AIR COOLING AND AIR-JET VORTEX GENERATOR ON FLOW STRUCTURE IN TURBINE PASSAGE

open access: yesTASK Quarterly, 2015
The paper concerns the experimental investigations and numerical simulations of a high loaded model of a turbine blade. An increase in the blade load leads to enlargement of a local supersonic zone terminated by a shock wave on the suction side.

Spectral denoising based on Hilbert–Huang transform combined with F-test

open access: yesFrontiers in Chemistry, 2022
Due to the influence of uncontrollable factors such as the environment and instruments, noise is unavoidable in a spectral signal, which may affect the spectral resolution and analysis result.

Experimental study on control of highly unsteady separating flow

open access: yesJournal of Fluid Science and Technology, 2014
An attempt to control an unsteady flow separation from a flat plate surface using a jet ejection is carried out. The unsteady flow is artificially generated by periodically moving a curved ceiling up and down at a constant frequency.

Control of leading edge separation on airfoil using DBD plasma actuator

open access: yesJournal of Fluid Science and Technology, 2014
This study deals with the separation control of an airfoil when a dielectric barrier discharge (DBD) plasma actuator is mounted on its leading edge. The experiments were performed at Reynolds number, Re ≈ 67,000 in an external airflow of 10 m/s.

AVERSIVE CONTROL: A SEPARATE DOMAIN? [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1984
Traditionally, aversive control has been viewed as a separate domain within behavior theory. Sometimes this separateness has been based upon a distinction between reinforcement and punishment, and sometimes upon a distinction between positive and negative reinforcement.
