Mathematical quantification of the spatial pattern of a city is, therefore, important for understanding various aspects of the system. In this work, a framework to char...

The colloidal particles experience an additional potential that is a superposition of repulsive potenti...

The model is developed within the framework of extended thermodynamics. It is shown that the entropy density of the mixture increases monotonically through ...

In the thermodynamic limit, all eigenstates of this model are exponentially localized in configuration...

]]>The ferromagnetic bidimensional Ising model with dipolar interactions has been proposed to model ultrathin films with strong out-of-plane anisotropy. The phase diagram presents a rich phenomenology that includes low-temperature phases characterized by stripes of width $n$ (${h}_{n}$) and a high-temperature p...

]]>We present an analytical approach to study simple symmetric random walks on a crossing geometry consisting of a plane square lattice crossed by ${n}_{l}$ number of lines that all meet each other at a single point (the origin) on the plane. The probability density to find the walker at a given distance from...

This leads to normal cell death, and extracellular matrix degradation allowing the formation of an interstitial gap between cancer and healthy cells. In this work, w...

]]>Hemodynamic modeling is used to explore the origin, predict, and analyze the power spectrum of the resting-state blood-oxygen-level-dependent (BOLD) signal measured by functional magnetic resonance imaging (fMRI), which has been reported to have a power-law form, i.e., $P\left(f\right)\propto {f}^{-s}$, where $P\left(f\right)$ is the po...

]]>Relaxation of suspended magnetic nanoparticles occurs via Brownian rotational diffusion of the particle as well as internal magnetization dynamics. The latter is often modeled by the stochastic Landau-Lifshitz equation, but its numerical treatment becomes prohibitively expensive in many practical ap...

]]>We conduct an in-depth analysis of the electroclinic effect in chiral, ferroelectric liquid crystal systems that have a first-order smectic-${A}^{*}$–smectic-${C}^{*}$ (Sm-${A}^{*}$–Sm-${C}^{*}$) transition, and show that such systems can be either type I or type II. In temperature-field parameter space type-I systems exhibit ...

Incommensurability of ${\theta}_{0}$ with three-dimensional (3D) close packing does not by itse...
