CORRELATING PHASE, MORPHOLOGY, AND STOICHIOMETRY OF OXYGEN ANNEALING FOR CRYSTALLINE VO₂ THIN FILMS
This study investigates the effects of annealing atmosphere (air vs. oxygen) and temperature on the properties of RF-sputtered VO2 thin films. XRD analysis revealed that annealing in an oxygen atmosphere preferentially enhances the formation of the monoclinic VO2 phase over V2O5 and reduces the...

INVERSE SCATTERING FOR THE DULLIN-GOTTWALD-HOLM EQUATION WITH A SOURCE
In this paper, the Cauchy problem for the Dullin–Gottwald–Holm equation with a source in the class of rapidly decreasing functions and a procedure is developed to construct the solution via the IST method is presented. In particular, from a physical perspective, it is analyzed that sources arise in...

EXTREMAL FUNCTIONS ON PARABOLIC MANIFOLDS AND REGULAR COMPACTS
This article considers parabolic Stein manifolds that admit special plurisubharmonic exhaustion functions. Using such a function, the notion of a 𝜌-polynomial is introduced. On manifolds possessing a rich family of such polynomials, we study maximal functions and regular compact sets for which...
