Neuronal hyperexcitability is a key feature in the early stages of Alzheimer's disease (AD). However, the underlying mechanisms have not been fully elucidated, particularly the impact of amyloid β-peptide (Aβ)-mediated astrocyte dysfuncti...

Following the concept of the red-king effect proposed by Bergstrom and Lachmann [Proc. Natl. Acad. Sci. USA 100, 593 (2003)10.1073/pnas.0134966100], a stochastic asymmetric replicator equation is developed to investigate the influence of en...

We examine the probability of the appearance of high values of the intensity I of a light beam at its propagation in the turbulent atmosphere. Starting from the functional integral representation of averages over turbulent fluctuations, we ...
Modeling of experimentally observed two-dimensional precursor solitons in a dusty plasma by the forced Kadomtsev-Petviashvili equation [0.03%]

In this paper we examine the relative knotting probabilities in a lattice model of ring polymers confined in a cavity. The model is of a lattice knot of size n in the cubic lattice, confined to a cube of side length L and with volume V=(L+1...
Modeling colloidal interactions using structural data: Insights from coated silica dispersions [0.03%]

The depth of a potential well plays a critical role in noise-assisted rate processes. Prevailing qualitative understanding suggests that the sizes of the fluctuations relative to the size of the basin of attraction in the bifurcation diagra...
