Special Issue Information

Dear Colleagues,

Advances in technology have opened the microscopic world to controlled experiments. For micro- and nanodevices, fluctuations are an unavoidable part of the behavior of such systems. Stochastic thermodynamics, a branch of non-equilibrium statistical physics, is a tool for the understanding of the heat and work exchanges at these scales.

Stochastic thermodynamics deals with small systems, interacting with heat, work, or particle reservoirs, and under external manipulation. The stochastic characteristic of thermodynamics led to new phenomena, such as the existence of fluctuation theorems, for heat and work, which govern non-equilibrium physics. One of its consequences is the apparent violation of the second law, or of Landauer’s principle. 

Since the equilibrium state is the state with the least information on it, for systems described by stochastic thermodynamics, there is very significant quantity of information. 

This Special Issue aims to be a channel for recent research on mesoscopic systems, such that their interactions can be well modelled by stochastic thermodynamics. It also aims to present special systems on the frontier of biology and physics, such as nano-machines and driven enzymes, and mesoscopic manipulated systems.

The precise mathematical description of gaze patterns remains a topic of ongoing debate, impacting the practical analysis of eye-tracking data. In this context, we present evidence supporting the appropriateness of a Lévy flight description for eye-gaze trajectories, emphasizing its beneficial scale-invariant properties. Our study focuses on utilizing these properties to aid in diagnosing Attention-Deficit and Hyperactivity Disorder (ADHD) in children, in conjunction with standard cognitive tests. Using this method, we found that the distribution of the characteristic exponent of Lévy flights statistically is different in children with ADHD. Furthermore, we observed that these children deviate from a strategy that is considered optimal for searching processes, in contrast to non-ADHD children. We focused on the case where both eye-tracking data and data from a cognitive test are present and show that the study of gaze patterns in children with ADHD can help in identifying this condition. Since eye-tracking data can be gathered during cognitive tests without needing extra time-consuming specific tasks, we argue that it is in a prime position to provide assistance in the arduous task of diagnosing ADHD.
