Usage


In science:

As with the AD solutions, the positive entropy gradient in the immediate post-shock flow, S ∝ (r/rvir )p with p ≈ 1, is due to the increasing strength of the accretion shock with cosmic time (Tozzi & Norman 2000).
Entropy Evolution in Galaxy Groups and Clusters; A Comparison of External and Internal Heating
For post heights h ≥ Lc , the gradient of both curves increases appreciably so that ǫ1 and ǫ3 grow relatively quickly with post height.
Topology and Bistability in liquid crystal devices
It might be helpful for the reader to look at the first version of posted in the arxiv where the authors gave a more transparent proof of a weaker upper bound C e−cR√log R in the long gradient curve theorem.
Random Complex Zeroes and Random Nodal Lines
They travel down the surface-density gradient, so there is no danger that the post-front Σ will not be larger than Σmin .
The disc instability model of dwarf-novae and low-mass X-ray binary transients
We expect that the spatial gradient terms in the fields will become large, and they must be included if we are are to make quantitative predictions about the role of chaos in the post-inflationary universe.
Chaos after Two-Field Inflation
The stronger gradient of the post-shock density for smaller ω is the reason for this behaviour.
Artificial broadening of the high-energy end of electron spectrum in supernova remnants
Sharma and Hammett (2006, personal communication) have found that for certain discontinous test problems this differencing can lead to negative temperatures; however, for our applications the temperature gradients are continuous and we observe post hoc that no such problems arise.
Saturation of the Magnetothermal Instability in Three Dimensions
This happens because the post-shock secondary wind expands faster than the primary wind and because of its long cooling time it has a pressure gradient parallel to the contact discontinuity.
