Aging refers to the property of two-time correlation functions to decay very slowly on (at least) two time scales. This phenomenon has gained recent attention due to experimental observations of the history dependent relaxation behavior in amorphous materials (“Glasses”) which pose a challenge to theorist. Aging signals the breaking of time-translational invariance and the violation of the fluc...

We study the dynamical heterogeneity and glassy dynamics in a kinetically constrained lattice-gas model which has both translational and rotational degrees of freedom. We find that the rotational relaxation time tracks the structural relaxation time as density is increased whereas the translational diffusion constant exhibits a strong decoupling. We investigate distributions of exchange and per...

In this article, to study the effect of pulse-type near-fault earthquakes on the seismic demands of steel moment frames, 15-story 2D-frame was analyzed under the influence of 20 near-fields with forward directivity effect and 2 far-field records. The relationship between Effective Cyclic Energy, ECE and displacement demands, velocity and hysteretic curve of SDOF systems in two near- and far-fau...

abstract: appealing to the principle of vertical residence and stemming the horizontal expansion of the city, the tehran milad tower is being built on 35000 sm3 site with the total area of 220000 sm3. with a height of over 170m, this 56-story concrete building is in the final stages of construction and would be the highest residential building of iran. since tehran is located in a high-risk ear...

Biographies are usually written about individuals who have fascinated us because of their accomplishments, opinions, or legacy. Although Western civilization recognizes the stories of the lives of biblical persons as well Greek and Roman philosophers and leaders, English literature attributes the first English biography to that of Samuel Johnson by James Boswell because of the detailed research...

In this note, we give a proof to the equality in law of a skewed stable variable and a nonlinear transformation of two independent uniform and exponential variables. The lack of an explicit proof of this formula has led to some inaccuracies in the literature. The Chambers et al. (1976) method of computer generation of a skewed stable random variable is based on this equality.

Environmental DNA (eDNA) holds great promise for conservation applications like the monitoring of invasive or imperiled species, yet this emerging technique requires ongoing testing in order to determine the contexts over which it is effective. For example, little research to date has evaluated how seasonality of organism behavior or activity may influence detection probability of eDNA. We appl...
