A filopodium is a cytoplasmic projection, exquisitely built and regulated, which extends from
the leading edge of the migrating cell, exploring the cell's neighborhood. Commonly …

Signal-processing molecules inside cells are often present at low copy number, which
necessitates probabilistic models to account for intrinsic noise. Probability distributions have …

The enormous catalytic power of natural enzymes relies on the ability to overcome the
bottleneck event in the enzymatic cycle, yet the underlying physical mechanisms are not fully …

In many real situations, randomness is considered to be uncertainty or even confusion which
impedes human beings from making a correct decision. Here we study the combined role of …

Cap** proteins are among the most important regulatory proteins involved in controlling
complicated stochastic dynamics of filopodia, which are dynamic finger-like protrusions used …

The past decade has seen great advances in our understanding of the role of noise in gene
regulation and the physical limits to signaling in biological networks. Here, we introduce the …

Molecular communications rely on diffusive propagation to transport information, which is
attractive for a variety of nano-scale applications. Due to the long-tail channel response …

During cell motion on a substratum, eukaryotic cells project sheetlike lamellipodia which
contain a dynamically remodeling three-dimensional actin mesh. A number of regulatory …

Recent modeling of filopodia—the actin-based cell organelles employed for sensing and
motility—reveals that one of the key limiting factors of filopodial length is diffusional transport …

The stochasticity of ion-channels dynamic is significant for physiological processes on
neuronal cell membranes. Microscopic simulations of the ion-channel gating with Markov …
