Interlayer coherent composite Fermi liquid phase in quantum Hall bilayers [PDF]
Composite fermions have played a seminal role in understanding the quantum Hall effect, particularly the formation of a compressible `composite Fermi liquid' (CFL) at filling factor nu = 1/2. Here we suggest that in multi-layer systems interlayer Coulomb

Preparation of ZnO/Brucite Functional Composite Powder by the Mechanochemical Method
In this experiment, ZnO/brucite composite powder was prepared through the mechanochemical method; further, the properties, particle morphology, and structure of the composite powder were characterized. The results show that mechanical grinding action can

Experimental and Numerical Study on the Strength of Repaired Steel Pipes with Composite Patches under Internal Pressure [PDF]
Considering the old methods of maintenance and repair of oil and gas pipelines such as welding or replacing a part of the damaged pipeline which include high costs and spending a lot of time, the important usage of novel methods with lower costs such as ...

A Supersymmetric Composite Model of Quarks and Leptons [PDF]
We present a class of supersymmetric models with complete generations of composite quarks and leptons using recent non-perturbative results for the low energy dynamics of supersymmetric QCD. In these models, the quarks arise as composite "mesons" and the

Adaptive Speaker Recognition Based on Hidden Markov Model Parameter Optimization
The Hidden Markov Model (HMM) is a widely used method for speaker recognition. During its training, the composite order of the measurement probability matrix and the number of re-evaluations of the initial model affect the speed and accuracy of a ...

The changing rules of the composite roughness in drainage pipelines with sediments
The deposition of sediments with different roughness increases uncertainty in the prediction of effective Manning's n (also known as composite roughness).
