Abstract: Gyárfás conjectured that for a given forest F, there exists an integer function f(F, x) such that $$\chi (G)\le f(F,\omega (G))$$χ(G)≤f(F,ω(G)) for each F-free graph G, where $$\omega (G)$$ω(G) is the clique number of G. The… read more here.

DOI: 10.1093/mnras/stab2555
Abstract: The effect of radiation pressure compression (RPC) on ionized gas in active galactic nuclei (AGNs) likely sets the photoionized gas density structure. The photoionized gas free–free absorption and emission are therefore uniquely set by the… read more here.

DOI: 10.1103/physreva.99.012705
Abstract: The effect of Coulomb interaction screening on non-relativistic free-free absorption is investigated by integrating the numerical continuum wave functions. The screened potential is taken to be in Debye-H\H{u}ckel (Yukawa) form with a screening length D.… read more here.

DOI: 10.1103/physreve.102.043209
Abstract: Cross sections for photo-induced bound-free and free-free transitions in plasmas are evaluated in the average-atom approximation and applied to determine opacities of dense plasmas of light elements. Parameters characterizing the plasmas (chemical potential, average ionic… read more here.

DOI: 10.1210/js.2019-sat-608
Abstract: Abstract Background: Levothyroxine overdose causing severe exogenous hyperthyroidism is not common. When it does occur, patients should be monitored clinically and biochemically until stable. Case Presentation: A 46 year old Caucasian female with a history… read more here.
