Optimizing the shielding properties of strength-enhanced concrete containing marble
The purpose of this study is to develop a low cost, locally produced concrete mixture with optimum marble content. The resulting mixture would have enhanced strength properties compared to the non-marble reference concrete, and improved radiation ...

Volatility Modeling via EWMA-Driven Time-Dependent Hurst Parameters [PDF]
We introduce a novel rough Bergomi (rBergomi) model featuring a variance-driven exponentially weighted moving average (EWMA) time-dependent Hurst parameter $H_t$, fundamentally distinct from recent machine learning and wavelet-based approaches in the ...

Brain functional connectivity during the first day of coma reflects long-term outcome
Objective: In patients with disorders of consciousness (DOC), properties of functional brain networks at rest are informative of the degree of consciousness impairment and of long-term outcome. Here we investigate whether connectivity differences between

MHz X-ray photon correlation spectroscopy using an acoustic levitator at the European XFEL
The structural and dynamical properties of soft-matter systems play an important role in crystallization and nucleation theory. Despite their significance, the dynamical properties are still poorly understood because of experimental constraints and the ...
