CMB temperature trispectrum of cosmic strings [PDF]
, 2010 We provide an analytical expression for the trispectrum of the cosmic microwave background (CMB) temperature anisotropies induced by cosmic strings. Our result is derived for the small angular scales under the assumption that the temperature anisotropy ...

Light‐Induced Entropy for Secure Vision
Advanced Materials, EarlyView.This work realized a ternary true random number generator by exploiting stochastic traps emerging within multiple junction interfaces, and quantitatively validated the generation of high‐quality random numbers. Furthermore, it successfully demonstrated diverse applications, including AI‐resilient image security, thereby providing a valuable guide for ...

Transient Response and Strength Analysis of Perforating String
Shiyou jixie, 2017 For a better understanding of dynamic response and stress intensity safety of the perforating tubular string under detonation loads, a finite element model of perforating tubular string has been established by using ANSYS.

Single and twin string cavitation swirling flows in multi-hole mini-sac diesel injector and sprays
Journal of Fluid Science and Technology, 2023 A new design of fuel injector for diesel engines is expected to enhance fuel spray atomization at the end of the fuel injection for the reduction in particulate matter emission. It was pointed out that string cavitation may occur in a multi-hole mini-sac

Averaged Methods for Vortex-String Evolution
, 1997 We discuss friction-dominated vortex-string evolution using a new analytic model recently developed by the authors. By treating the average string velocity, as well as the characteristic lengthscale, as dynamical variables, we can provide a quantitative ...

Low-velocity cosmic strings in accelerating universe
, 2011 The standard cosmological model supposes that the dominant matter component changes in the course of the evolution of the universe. We study the homogeneous and isotropic universe with non-zero cosmological constant in the epoch when the dominant matter component has a form of a gas of low-velocity cosmic strings.

Velocity String Drainage Technology for Horizontal Gas Wells in Changbei
Processes, 2022 The Changbei gas field is dominated by wells with large horizontal displacement, which have exhibited high gas production performance at an early stage of development. With the decrease in reservoir pressure, the liquid loading in the gas well is relatively high and gas production rapidly decreases. Therefore, suitable drainage measures are required to

Superionic Amorphous Li2ZrCl6 and Li2HfCl6
Advanced Materials, EarlyView.Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the

Development of the Optimum Design Software for CT Velocity String
Shiyou jixie, 2018 There is no coiled tubing velocity string optimization design software in China, and the calculation model of foreign related software is old fashioned with difficult operation, whose function does not meet the on-site demand. To address the issue, using
