The depletion attraction: an underappreciated force driving cellular organization

Entropic contributions to the splicing process.

It has been recently argued that depletion attraction may play an important role in different aspects of cellular organization, ranging from the organization of transcriptional activity in transcription factories to the formation of nuclear bodies. In this paper, we suggest a new application of these ideas in the context of the splicing process, a crucial step of messenger RNA maturation in euk...

Influence of polymer-pore interactions on translocation.

We investigate the influence of polymer-pore interactions on the translocation dynamics using Langevin dynamics simulations. An attractive interaction can greatly improve the translocation probability. At the same time, it also increases the translocation time slowly for a weak attraction while an exponential dependence is observed for a strong attraction. For fixed driving force and chain leng...

What Is The Driving Force Behind Industrial Development In Iran? Rent Seeking And Labor Exploitation As The Driving Force Of Industrial Growth

Safety Considerations on MRI Systems for Firefighters and Paramedics

Background and Objectives: The use of Magnetic Resonance Imaging (MRI) systems is on the rise and the number of installed systems is constantly increasing all over the world. This raises the possibility for emergency personnel to get in contact with these systems. However, the clothing and working material of paramedics and firefighters is not designed for the use on magnets. M...

Understanding Depletion Induced Like-Charge Attraction from Self-Consistent Field Model

The interaction force between likely charged particles/surfaces is usually repulsive due to the Coulomb interaction. However, the counterintuitive like-charge attraction in electrolytes has been frequently observed in experiments, which has been theoretically debated for a long time. It is widely known that the mean field PoissonBoltzmann theory cannot explain and predict this anomalous feature...
