Ranjan et al. @Phys. Rev. B 65, 060102~R! ~2002!# have recently presented results of a powder neutrondiffraction study of the high-temperature monoclinic (FM ) to low-temperature monoclinic (FM ) phase transition in Pb(Ti12xZrx)O3 discovered by Ragini et al. @Phys. Rev. B 64, 054101 ~2001!#. They attribute the presence of superlattice reflections in the diffraction data to tilting of oxygen oct...

Let K be a closed convex cone with the nonempty interior in a real Banach space and cc(K) denote the family of all nonempty convex compact subsets of K. If {F t : t ≥ 0} is a concave iteration semigroup of continuous linear set-valued functions F t : K → cc(K) with F (x) = {x} for x ∈ K, then DtF (x) = F (G(x)) for x ∈ K and t ≥ 0, where DtF (x) denotes the Hukuhara derivative of F (x) with res...

A new antitumor antibiotic gilvusmycin was isolated from the culture broth of Streptomyces sp. QM16. The structure of gilvusmycin was related to CC-1065 and determined by NMR spectral analysis. Gilvusmycin exhibited antitumor activity against murine leukemia P388 in vivo.

Max-SAT-CC is the following optimization problem: Given a formula in CNF and a bound k, find an assignment with at most k variables being set to true that maximizes the number of satisfied clauses among all such assignments. If each clause is restricted to have at most ` literals, we obtain the problem Max-`SAT-CC. Sviridenko (Algorithmica, 30(3):398–405, 2001) designed a (1− e−1)-approximation...

Active edible films were prepared by adding carvacrol into sodium caseinate (SC) and calcium caseinate (CC) matrices plasticized with two different glycerol concentrations (25 and 35 wt%) prepared by solvent casting. Functional characterization of these bio-films was carried out by determination of some of their physico-chemical properties, such as colour, transparency, oxygen barrier, wettabil...
