Relaxation processes in a closed chemical reaction-diffusion system which can potentially form Turing-like patterns during the transient are investigated to address the question given by the title. We find that when certain conditions are fulfilled the relaxation process is indeed drastically hindered, once the pattern is formed. This slowing down is shown to be due to stepwise relaxation, wher...

The dynamical facilitation scenario, by which localized relaxation events promote nearby relaxation events in an avalanche process, has been suggested as the key mechanism connecting the microscopic and the macroscopic dynamics of structural glasses. Here we investigate the statistical features of this process via numerical simulations of a model structural glass. First we show that the relaxat...

This paper describes techniques to restrict and to heuristically control relaxation of deductive database queries. The process of query relaxation provides a user with a means to automatically identify new queries that are related to the user's original query. However, for large databases, many relaxations may be possible. The methods to control and restrict the relaxation process introduced in...

The logarithmic relaxation process is the slowest of all relaxation processes and is exhibited by only a few molecular liquids and proteins. Bulk salol, which is a glass-forming liquid, is known to exhibit logarithmic decay of intermediate scattering function for the β-relaxation process. In this article, we report the influence of nanoscale confinements on the logarithmic relaxation process an...

We consider a frustrated spin model with a glassy dynamics characterized by a slow component and a fast component in the relaxation process. The slow process involves variables with critical behavior at finite temperature Tp and has a global character like the (structural) α-relaxation of glasses. The fast process has a more local character and can be associated to the β-relaxation of glasses. ...

abstract background: fatigue is the most common and highly disabling symptom of multiple sclerosis (ms) that has negative effects on employment, the process of socialization, compliance with the disease, and other factors effective on activities of daily living. the usage of complementary and alternative medicine methods in ms patients is higher than in the general population. however, there is...

the effect of mixing on rheological behavior of 6% wt epoxy-clay nanocomposites was studied. the mixing processes were carried out by low shear mixer, homogenizer and ultrasonic and combination of different mixing techniques at medium and maximum power. all these methods led to intercalated structure. the xrd results showed that the ultrasonic has the best effect on dispersion while a low shear...

In the Hoppeld network, a solution of an optimization problem is obtained after the network is relaxed to an equilibrium state. This paper shows that the performance of the Hoppeld network can be improved by using a relaxation rate to control the relaxation process. Analysis suggests that the relaxation process has an important impact on the quality of a solution. A relaxation rate is then intr...
