We derive the statistics of the efficiency under the assumption that thermodynamic fluxes fluctuate with normal law, parametrizing it in terms of time, macroscopic efficiency, and a coupling parameter ζ. It has a peculiar behavior: no moments, one sub-, and one super-Carnot maxima corresponding to reverse operating regimes (engine or pump), the most probable efficiency decreasing in time. The l...

Abstract This work aims at studying the impact of SARS-CoV-2 pandemic on global financial markets. In particular, such is analysed through changes shape implied volatility smile options written several equity indexes and stocks. The function estimated using market-based information liquid applying a semi-parametric smoothing technique that exploits kernel no-arbitrage conditions. Such approach ...

The theme of this research is burnout at work in modern times. The main objective is to analyze aspects of mental health worker. The specific objectives are to evaluate the issue of health and mental illness in the workplace, to understand the field of psychodynamics of work, and to analyze the work and the mental strain. The methodology used is the literature review. We conclude that is not th...

Continuous-time random walks (CTRW) play an important role in understanding of a wide range of phenomena. However, most theoretical studies of these models concentrate only on dynamics at long times. We present a new theoretical approach, based on generalized master equations picture, which allowed us to obtain explicit expressions for Laplace transforms for all dynamic quantities for different...
