Measuring positive public transit accessibility using big transit data

open access: yesGeo-spatial Information Science, 2021
Most of the current existing accessibility measures quantify the potential of reaching desirable opportunities across space and time. Nevertheless, these potential measurements only illustrate the maximum possible accessibility a person can have, which ...

The chemokine receptor CXCR4 regulates satellite cell activation, early expansion, and self-renewal, in response to skeletal muscle injury

open access: yesFrontiers in Cell and Developmental Biology, 2022
Acute skeletal muscle injury is followed by satellite cell activation, proliferation, and differentiation to replace damaged fibers with newly regenerated muscle fibers, processes that involve satellite cell interactions with various niche signals.

Hypersatellite and satellite transitions in xenon atoms

open access: yesPhysical Review A, 1990
Decay of double-K-shell-vacancy states in xenon atoms, created in the decay of 131Cs, was investigated. The measurements were performed with a pair of germanium detectors, a fast-slow coincidence system, and a three-parameter pulse-height analyzer. In the analysis of the two-dimensional E1-E2 spectrum, improved least-squares routines were applied.
