An Analytical Solution for the Frost Heaving Force considering the Freeze-Thaw Damage and Transversely Isotropic Characteristics of the Surrounding Rock in Cold-Region Tunnels

Advances in Civil Engineering, 2020
Frost damage is a frequent occurrence in cold regions and can threaten the normal use and structural stability of tunnel engineering projects. To accurately determine the frost heaving force and effectively evaluate the frost damage in cold-region ...

Paired Superfluidity and Fractionalized Vortices in Spin-orbit Coupled Bosons

, 2011
In this letter we study finite temperature properties of spin-1/2 interacting bosons with spin-orbit coupling in two dimensions. When the ground state has stripe order, we show that thermal fluctuations will first melt the stripe order and lead to a ...

Robust and Fast Normal Mollification via Consistent Neighborhood Reconstruction for Unorganized Point Clouds

Sensors, 2023
This paper introduces a robust normal estimation method for point cloud data that can handle both smooth and sharp features. Our method is based on the inclusion of neighborhood recognition into the normal mollification process in the neighborhood of the

Momentum anisotropy of the scattering rate in cuprate superconductors

, 2004
We examine the momentum and energy dependence of the scattering rate of the high temperature cuprate superconductors using angle resolved photoemission spectroscopy. The scattering rate is of the form a + b*w.

Seismic AVOA Inversion for Weak Anisotropy Parameters and Fracture Density in a Monoclinic Medium

Applied Sciences, 2020
In shale gas development, fracture density is an important lithologic parameter to properly characterize reservoir reconstruction, establish a fracturing scheme, and calculate porosity and permeability.

Differentiation of osteosarcoma from osteomyelitis using microarchitectural analysis on panoramic radiographs

Scientific Reports, 2022
Diagnosing osteosarcoma (OS) is very challenging and OS is often misdiagnosed as osteomyelitis (OM) due to the nonspecificity of its symptoms upon initial presentation.

Normal form analysis of bouncing cycles in isotropic rotor stator contact problems [PDF]

International Journal of Mechanical Sciences, 2019
Abstract This work considers analysis of sustained bouncing responses of rotating shafts with nonlinear lateral vibrations due to rotor stator contact. The insight that this is an internal resonance phenomena makes this an ideal system to be studied with the method of normal forms, which assumes that a system may be modelled primarily in terms of ...

On parameter estimation for N(μ,σ2I3) based on projected data into S2

Modern Stochastics: Theory and Applications
The projected normal distribution, with isotropic variance, on the 2-sphere is considered using intrinsic statistics. It is shown that in this case, the expectation commutes with the projection, and that the covariance of the normal variable has a 1-1 ...

Influence of elastic anisotropy on the shapes of ellipsoidal blisters and stress field around the blisters in solid materials

AIP Advances, 2023
To address the embrittlement challenges posed by gas blisters in anisotropic materials, the stable shape of constant-pressure blisters in anisotropic materials (hexagonal, tetragonal, and rhombohedral) was energetically investigated based on continuum ...
