Preliminary estimation of rock-fall lateral dispersion by laboratory test

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Lateral dispersion significantly directs the assessment of rockfall hazard and design of countermeasures. In the present study, the dependence of lateral dispersion on different controlling factors has been systematically evaluated by performing ...

A Bayesian Negative Binomial Hierarchical Model for Identifying Diet–Gut Microbiome Associations

open access: yesFrontiers in Microbiology, 2021
The human gut microbiota composition plays an important role in human health. Long-term diet intervention may shape human gut microbiome. Therefore, many studies focus on discovering links between long-term diets and gut microbiota composition.

The Turbulence Spectrum of Molecular Clouds in the Galactic Ring Survey: A Density-Dependent PCA Calibration [PDF]

open access: yes, 2011
Turbulence plays a major role in the formation and evolution of molecular clouds. The problem is that turbulent velocities are convolved with the density of an observed region.

Non-Dirac topological surface states in (SnTe)$_{n\geq2}$(Bi$_2$Te$_3$)$_{m=1}$ [PDF]

open access: yes, 2015
A new type of topological spin-helical surface states was discovered in layered van der Waals bonded (SnTe)$_{n=2,3}$(Bi$_2$Te$_3$)$_{m=1}$ compounds which comprise two covalently bonded band inverted subsystems, SnTe and Bi$_2$Te$_3$, within a building ...

Stellar populations of cluster E and S0 galaxies [PDF]

open access: yes, 1997
Spectral line indices for a sample of 290 nearby E and S0 galaxies are used to investigate the stellar populations of these galaxies. Relations are established between the line indices (Mg2, , Hbeta) and the velocity dispersions, the masses of the ...

Modeling a Wave on Mild Sloping Bottom Topography and Its Dispersion Relation Approximation

open access: yesKubik, 2022
Linear wave theory is a simple theory that researchers and engineers often use to study a wave in deep, intermediate, and shallow water regions. Many researchers mostly used it over the horizontal flat seabed, but in actual conditions, sloping seabed ...

Tailored Gires–Tournois etalons as tunable dispersion slope compensators [PDF]

open access: yesOptics Letters, 2004
We present a novel concept of a tailored Gires-Tournois etalon structure and show that such a device is useful for the fabrication of a dispersion-slope compensator with an almost arbitrary dispersion profile and also with tunability in the dispersion slope.

On the universality of the global slope -- anisotropy inequality [PDF]

open access: yes, 2010
Recently, some intriguing results have lead to speculations whether the central density slope -- velocity dispersion anisotropy inequality (An & Evans) actually holds at all radii for spherical dynamical systems.
