Correlation between Noise and Microstructure in CoCrTa Media.

Correlation between Allergic Rhinitis and Otitis Media with Effusion

Introduction: Otitis media with effusion (OME) is prevalent among children in such a way that it is the most common cause of hearing loss and surgery in childhood. Immunoglobulin E (IgE) mediated hypersensitivity has been proposed as a causative factor in the development of OME; however, there has been contrasting data in this regard. Therefore, the present study aimed to detect the possi...

Correlation of switching volume with magnetic properties, microstructure, and media noise in CoCr(Pt)Ta thin films

Noise effect on fatigue: correlation between the subjective and objective indicators.

Introduction: Fatigue is the exhaustion of the body or spirit that can be caused by stress, excessive work, drug use, or physical or mental illness. Fatigue is a factor in reducing productivity and incidents. Therefore, measuring is important. The aim of this study was to determine the fatigue measurement measurements based on objective and objective indices. Materials and Methods: A cross-s...

Volatility or microstructure noise?

The notion of realized volatility as a model-free measurement of the quadratic variation of the underlying log price process loses its asymptotic validity in the presence of market microstructure noise. Should microstructure contaminations be present, the summing of an increasing number of squared return data (as in the definition of the realized volatility estimator) simply entails increasing ...

On the Correlation Structure of Microstructure Noise in Theory and Practice

We argue for incorporating the financial economics of market microstructure into the financial econometrics of asset return volatility estimation. In particular, we use market microstructure theory to derive the cross-correlation function between latent returns and market microstructure noise, which feature prominently in the recent volatility literature. The cross-correlation at zero displacem...
