Modulus on graphs as a generalization of standard graph theoretic quantities

, 2015
This paper presents new results for the modulus of families of walks on a graph---a discrete analog of the modulus of curve families due to Beurling and Ahlfors. Particular attention is paid to the dependence of the modulus on its parameters.

Natural Inflation with Natural Trans-Planckian Axion Decay Constant from Anomalous $U(1)_X$ [PDF]

, 2014
We propose a natural inflation model driven by an imaginary or axionic component of a K\"ahler modulus in string-inspired supergravity. The shift symmetry of the axion is gauged under an anomalous $U(1)_X$ symmetry, which leads to a modulus-dependent ...

Rheological Properties of Bitumens from the Perspective their Chemical Composition

Civil and Environmental Engineering, 2019
The quality of bituminous binders is commonly evaluated by the empirical tests. The functional approach to the evaluation of bitumen properties is a trend that has been applied in the last years.

Dark Radiation and Dark Matter in Large Volume Compactifications

, 2012
We argue that dark radiation is naturally generated from the decay of the overall volume modulus in the LARGE volume scenario. We consider both sequestered and non-sequestered cases, and find that the axionic superpartner of the modulus is produced by ...

DNA loop statistics and torsional modulus [PDF]

, 2004
The modelling of DNA mechanics under external constraints is discussed. Two analytical models are widely known, but disagree for instance on the value of the torsional modulus. The origin of this embarassing situation is located in the concept of writhe.

Dynamic Modulus Prediction of a High‐Modulus Asphalt Mixture

Advances in Civil Engineering, 2021
Dynamic modulus is a key evaluation index of the high‐modulus asphalt mixture, but it is relatively difficult to test and collect its data. The purpose is to achieve the accurate prediction of the dynamic modulus of the high‐modulus asphalt mixture and further optimize the design process of the high‐modulus asphalt mixture.
