Models predict that CO• doubling in the desefi• by Miohelangeli et al. (1992) and it includes the atmosphere cools the stratosphere by as much as 10øC. We effects ofabsorption, Rayleigh and aerosol scattering without argue that this effect alone, through the temperature polarization. dependence of the ozone spectrum, can result in an increase In this model, the temperature-dependent ozone absor...

Let K and X be compact plane sets such that K X. Let P(K)be the uniform closure of polynomials on K. Let R(K) be the closure of rationalfunctions K with poles o K. Dene P(X;K) and R(X;K) to be the uniformalgebras of functions in C(X) whose restriction to K belongs to P(K) and R(K),respectively. Let CZ(X;K) be the Banach algebra of functions f in C(X) suchthat fjK = 0. In this paper, we show th...

Using muon spin relaxation measurements on formamidinium lead iodide [FAPbI3, where FA denotes HC(NH2)2], we show that, among the five structurally distinct phases of FAPbI3 exhibited through two different temperature hysteresis, reorientation motion molecules is quasi-static below ≈50 K over time scale 10−6 s in low-temperature (LT) hexagonal (Hex-LT, <160 K) phase, which has a relative...

for every positive integer k, a set s of vertices in a graph g = (v;e) is a k- tuple dominating set of g if every vertex of v -s is adjacent to at least k vertices and every vertex of s is adjacent to at least k - 1 vertices in s. the minimum cardinality of a k-tuple dominating set of g is the k-tuple domination number of g. when k = 1, a k-tuple domination number is the well-studied domination...
