Velocity and Velocity-Difference Distributions in Burgers Turbulence [PDF]

open access: yesPhysical Review Letters, 2004
We consider the one-dimensional Burgers equation randomly stirred at large scales by a Gaussian short-time correlated force. Using the method of dissipative anomalies, we obtain velocity and velocity-difference probability density functions and confirm the results with high-resolution numerical simulations.

First radial velocity results from the MINiature Exoplanet Radial Velocity Array (MINERVA) [PDF]

open access: yes, 2019
The MINiature Exoplanet Radial Velocity Array (MINERVA) is a dedicated observatory of four 0.7m robotic telescopes fiber-fed to a KiwiSpec spectrograph. The MINERVA mission is to discover super-Earths in the habitable zones of nearby stars.

Subsonic near-surface P-velocity and low S-velocity observations using propagator inversion [PDF]

open access: yes, 2005
Detailed knowledge of near-surface P- and S-wave velocities is important for processing and interpreting multicomponent land seismic data because (1) the entire wavefield passes through and is influenced by the near-surface soil conditions, (2) both ...

Effect of sprinting velocity on anterior cruciate ligament and knee load during sidestep cutting

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
The purpose of the study was to investigate the effect of an increase in sprinting velocity on the anterior cruciate ligament (ACL) load, knee joint load, and activation of femoral muscles using the musculoskeletal modeling approach. Fourteen high school

An Unbiased Estimator of Peculiar Velocity with Gaussian Distributed Errors for Precision Cosmology [PDF]

open access: yes, 2014
We introduce a new estimator of the peculiar velocity of a galaxy or group of galaxies from redshift and distance estimates. This estimator results in peculiar velocity estimates which are statistically unbiased and that have errors that are Gaussian ...

The mass-velocity and intensity-velocity relations in jet-driven molecular outflows [PDF]

open access: yes, 2003
We use numerical simulations to examine the mass-velocity and intensity-velocity relations in the CO J=2-1 and H$_2$ S(1)1-0 lines for jet-driven molecular outflows. Contrary to previous expectations, we find that the mass-velocity relation for the swept-

Ultrasound as a Tool to Study Muscle–Tendon Functions during Locomotion: A Systematic Review of Applications

open access: yesSensors, 2019
Movement science investigating muscle and tendon functions during locomotion utilizes commercial ultrasound imagers built for medical applications. These limit biomechanics research due to their form factor, range of view, and spatio-temporal resolution.
