Holographic predictions for cosmological 3-point functions [PDF]

, 2011
We present the holographic predictions for cosmological 3-point correlators, involving both scalar and tensor modes, for a universe which started in a non-geometric holographic phase.

Study of Residual Stresses in Bimetallic Work Rolls [PDF]

Advanced Materials Research, 2014
An experimental campaign of compression tests, differential thermal analysis (DTA), differential scanning calorimetry (DSC), dilatometry and microstructure analysis has been performed, as well as the identification of the material data set for finite element (FE) analysis of bimetallic rolls.

Consistency condition for inflation from (broken) conformal symmetry

, 2013
We investigate the symmetry constraints on the bispectrum, i.e. the three-point correlation function of primordial density fluctuations, in slow-roll inflation.

Optimization design of a novel X-type six-high rolling mill based on maximum roll system stiffness.

PLoS ONE, 2020
The present investigation devices a novel X-type six-high (X-6h) mill. In addition, parametric models of different roll layouts such as the four-high (4-h), I-type six-high (I-6h), and X-6h mills are established. Three-dimensional (3D) finite element (FE)

A new sensor for the evaluation of contact stress by inverse analysis during steel strip rolling [PDF]

, 2011
International audienceKnowledge of the contact stress between roll and strip becomes a critical factor in modern, high-speed rolling mills. In this paper, an inverse analytical method is developed to determine the contact stress in the roll gap by ...

Revisiting Cosmic No-Hair Theorem for Inflationary Settings

, 2012
In this work we revisit Wald's cosmic no-hair theorem in the context of accelerating Bianchi cosmologies for a generic cosmic fluid with non-vanishing anisotropic stress tensor and when the fluid energy momentum tensor is of the form of a cosmological ...

Response mechanism of matrix microstructure evolution and mechanical behavior to Mg/Al composite plate by hard-plate accumulative roll bonding

Journal of Materials Research and Technology, 2023
In the traditional accumulative roll bonding (ARB) process of heterogeneous composite laminates, due to the excessive strain caused by accumulative roll bonding, many problems such as reduction of plasticity and cracks on the edge of composite plates ...
