A general mechanism for enhancer-insulator pairing reveals heterogeneous dynamics in long-distant 3D gene regulation
Cells regulate fates and complex body plans using spatiotemporal signaling cascades that alter gene expression.
Multifractal-spectral features enhance classification of anomalous diffusion
To accomplish this, we generate extensive datasets comprising $10^6$ trajectories from these five anomalous diffusion models and extract multiple multifractal spectra from each trajectory.
Target search on DNA -- effect of coiling
Some proteins can find their targets on DNA faster than by pure diffusion in the three-dimensional cytoplasm, through the process of facilitated diffusion: They can loosely bind to DNA and temporarily slide along it, thus being guided by the DNA molecule itself to the target.
Machine-Learning Solutions for the Analysis of Single-Particle Diffusion Trajectories
Single-particle traces of the diffusive motion of molecules, cells, or animals are by-now routinely measured, similar to stochastic records of stock prices or weather data.
Ergodic characterization of non-ergodic anomalous diffusion processes
Canonical characterization techniques that rely upon mean squared displacement ($\mathrm{MSD}$) break down for non-ergodic processes, making it challenging to characterize anomalous diffusion from an individual time-series measurement.
Preface: Characterisation of Physical Processes from Anomalous Diffusion Data
Preface to the special issue "Characterisation of Physical Processes from Anomalous Diffusion Data" associated with the Anomalous Diffusion Challenge ( https://andi-challenge. org ) and published in Journal of Physics A: Mathematical and Theoretical.
The fate of the American dream: A first passage under resetting approach to income dynamics
Detailed knowledge of individual income dynamics is crucial for investigating the existence of the American dream: Are we able to improve our income status during our working life?
Income inequality and mobility in geometric Brownian motion with stochastic resetting: theoretical results and empirical evidence of non-ergodicity
We explore the role of non-ergodicity in the relationship between income inequality, the extent of concentration in the income distribution, and mobility, the feasibility of an individual to change their position in the income distribution.
Generalised geometric Brownian motion: Theory and applications to option pricing
Classical option pricing schemes assume that the value of a financial asset follows a geometric Brownian motion (GBM).
Towards a full quantitative description of single-molecule reaction kinetics in biological cells
The first-passage time (FPT), i. e., the moment when a stochastic process reaches a given threshold value for the first time, is a fundamental mathematical concept with immediate applications.
Random Multi-Hopper Model. Super-Fast Random Walks on Graphs
Stated differently, for small parameter values the multi-hopper explores a general graph as fast as possible when compared to a random walker on a full graph.
