Forecasting VIX with Hurst Exponent
, 2022 The VIX is a proxy for the implied volatility, computed con- sidering Standard & Poor’s 500 Index data. It widely regarded as a mea- sure of turbulence in U.S. and global financial markets.

Beyond Quality and Quantity: Enriching the Study of Organizational Attention
Journal of Management Studies, EarlyView.Abstract This Counterpoint advances the study of organizational attention by proposing an ‘expansive’ rather than a ‘substitutive’ development of the attention‐based view (ABV) as proposed in the Point. While endorsing a richer understanding of attention, we caution against reinforcing unhelpful dichotomies between quality and quantity of attention. We

Investigation of non linear dynamics of an excitable magnetron sputtering plasma
Results in Physics, 2019 In this paper nonlinear dynamical behaviour of an excitable DC magnetron sputtering plasma has been investigated. Initially, plasma exhibited fixed point dynamics whereas with the increase in the discharge voltage, spikes were observed in the floating ...

Testing for Rough Volatility When Prices Are Purely Discontinuous
Journal of Time Series Analysis, EarlyView.ABSTRACT We consider the problem of nonparametric testing for rough volatility, using high‐frequency data with a fixed time span, in a setting where the price is purely discontinuous. More specifically, we analyze the asymptotic properties of a test we developed in previous work in a pure‐jump setting.

Deep Neural Network Model for Hurst Exponent: Learning from R/S Analysis
MathematicsThis paper proposes a deep neural network (DNN) model to estimate the Hurst exponent, a crucial parameter in modelling stock market price movements driven by fractional geometric Brownian motion.

Self-affine subglacial roughness: consequences for radar scattering and basal water discrimination in northern Greenland [PDF]
The Cryosphere, 2017 Subglacial roughness can be determined at a variety of length scales from radio-echo sounding (RES) data either via statistical analysis of topography or inferred from basal radar scattering.
