Mechanical Properties and Engineering Applications of Special Soils—Dynamic Shear Modulus and Damping of MICP-Treated Calcareous Sand at Low Strains

open access: yesApplied Sciences, 2022
Calcareous sand deposits are widespread along the shoreline in tropical and subtropical regions. Microbially induced calcite precipitation (MICP) treatment is a new method for improving the soil’s stiffness and strength.

Arm cavity resonant sideband control for laser interferometric gravitational wave detectors [PDF]

open access: yes, 1999
We present a new optical control scheme for a laser interferometric gravitational wave detector that has a high degree of tolerance to interferometer spatial distortions and noise on the input light.

The TIGA technique for detecting gravitational waves with a spherical antenna [PDF]

open access: yes, 1997
We report the results of a theoretical and experimental study of a spherical gravitational wave antenna. We show that it is possible to understand the data from a spherical antenna with 6 radial resonant transducers attached to the surface in the ...

A new perspective on the irregular satellites of Saturn - I Dynamical and collisional history [PDF]

open access: yes, 2008
The dynamical features of the irregular satellites of the giant planets argue against an in-situ formation and are strongly suggestive of a capture origin.

Characteristics of small-strain shear modulus of Zhanjiang clay under influence of inherent anisotropy

open access: yesYantu gongcheng xuebao, 2021
In order to investigate the influence of inherent anisotropy on the small-strain shear modulus of Zhanjiang clay, a series of resonance column tests are carried out on the specimens with α=0°, 22.5°, 45°, 67.5°, and 90° under different confining ...

Resonant Cyclotron Radiation Transfer Model Fits to Spectra from Gamma-Ray Burst GRB870303 [PDF]

open access: yes, 1999
We demonstrate that models of resonant cyclotron radiation transfer in a strong field (i.e. cyclotron scattering) can account for spectral lines seen at two epochs, denoted S1 and S2, in the Ginga data for GRB870303.
