Integrins are essential receptors for the development and functioning of multicellular animals because they mediate cell adhesion and migration, and regulate cell proliferation and apoptosis. Ligand-dependent activation of integrins involves the formation of receptor clusters and this has been...

We consider the non-Markovian Langevin evolution of a dissipative dynamical system in quantum mechanics in the path integral formalism. After discussing the role of the frequency cutoff for the interaction of the system with the heat bath and the kernel and noise correlator that follow from the...

We study the adsorption problem of linear polymers, immersed in a good solvent, when the container of the polymer–solvent system is taken to be a member of the Sierpinski gasket (SG) family of fractals, embedded in the three-dimensional Euclidean space. Members of the SG family are enumerated...

The Monte Carlo Simulation (MCS) and the Effective Field Theory (EFT) have been used to study the magnetic properties of a small particle on an hexagonal substrate at temperatures below, around and above the critical temperature. The system is described by a mixed-spin Ising model in which the...

The main purpose of the paper is to show that there exists intrinsically stochastic circular motion in a pairwise epidemic model, which does not exist in the classical mean-field susceptible–infective–susceptible (SIS) models. Here a basic pairwise SIS epidemic model is adopted. By the...

Recently, a morphological transition in the velocity distribution of a relativistic gas has been pointed out which shows hallmarks of a critical phenomenon. Here, we provide a general framework which allows for a thermodynamic approach to such a critical phenomenon. We therefore construct a...

A new discrete element model (DEM) has been developed for the purpose of simulating dynamic fracturing driven by the internal generation of fluids in low permeability elastic solid bodies. The elastic material is represented by a network of nodes connected by springs, and fracture nucleation and...

In view of same time delay τ in active and passive transmission processes with colored noises of intracellular Ca2+, by means of second-order algorithm for stochastic simulation colored noises, the normalized autocorrelation function (NAF) and the characteristic correlation time (CCT) of...

Nonunitary quantum operations generating thermostatistical states and forming positive operator-valued measures (POVMs) are of current interest as a useful tool for operational approach to quantum thermodynamics. Here, two different operations generating the same thermostatistical state are...

Daily mean temperature records over China during the past 50 years are studied by means of detrended cross-correlation analysis (DCCA). Taking Beijing as a center, we calculate the DCCA cross-correlation coefficient σDCCA between the temperatures in Beijing and those in other stations. After a...
