As one of the recently proposed algorithms for sparse system identification, l0 norm constraint Least Mean Square (l0-LMS) algorithm modifies the cost function of the traditional method with a penalty of tap-weight sparsity. The performance of l0-LMS is quite attractive compared with its various precursors. However, there has been no detailed study of its performance. This paper presents compre...

Dimetal complexes of a new N-heterocyclic carbene/phenanthroline ligand have been synthesized. Coordination of both ruthenium and rhenium to the phenanthroline moiety in combination with platinum at the carbene moiety are reported. Steady-state and time-resolved optical absorption and photoluminescence spectra were obtained for the complexes. These results illustrate significant changes occur w...

In the present paper, we study notion of Schur multiplier M(L) an n-Lie superalgebra L=L0?L1 and prove that dim M(L)??i=0n(mi)L(n?i,k), where L0=m, L1=k, L(0,k)=1 L(t,k)=?j=1t(t?1j?1)(kj), for 1?t?n. Moreover, obtain upper bound dimension in which L is a nilpotent with one-dimensional derived superalgebra. It also provided several inequalities on as well analogue converse Schur’s theorem.

In this study, 1,10-phenanthroline molecules were introduced in the interlayer space of a paramagnetic synthetic saponite clay containing both Eu3+ and Gd3+ ions structural positions. Two samples with different loading phenanthroline dye prepared. The resulting hybrid materials possessed improved optical emission properties due to an efficient antenna effect from centers; was demonstrated be hi...

Definition 1.1 T is small if for all n < ω, |Sn(∅)| ≤ ω. Remark 1.2 If T is small, then there is a countable L0 ⊆ L such that for every φ(x) ∈ L there is some φ′(x) ∈ L0 such that in T , φ(x) ≡ φ′(x). Hence, T is a definitional extension of the countable theory T0 = T L0. Proof: See Remark 14.25 in [4]. With respect to the second assertion, consider some n-ary relation symbol R ∈ LrL0. There is...

A simple, sensitive, and convenient spectrophotometric method for the determination of diclofenac sodium and piroxicam in pure form and in pharmaceutical formulations was developed. The method is based on the oxidation of diclofenac sodium or piroxicam by iron(III) in the presence of o-phenanthroline. The formation of tris(o-phenanthroline) iron(II) complex (ferroin) upon the reaction of diclof...

The reaction of equimolar amounts of zinc bromide and 2,9-dimethyl-1,10-phenanthroline in dry methanol provided the title compound, [ZnBr(2)(C(14)H(12)N(2))], in good yield. The Zn(II) ion is coordinated in a distorted tetra-hedral environment by two N atoms from the chelating 2,9-dimethyl-1,10-phenanthroline ligand and two bromide ions. There is inter-molecular π-π stacking between adjacent ph...

ABSTRACT. A mixed-ligand zinc(II) complex, [Zn(Hpma)(phen)Cl] (where Hpma– = N-(2,6-dimethylphenyl)oxamate and phen 1,10-phenanthroline), has been prepared by the reaction of zinc chloride, ethyl (2,6-dimethylphenylcarbamoyl)formate (Hdmp) 1,10-phenanthroline under basic conditions in dimethylformamide. The structure complex was characterised elemental analysis, IR, 1H-NMR, UV-Vis absorption X-...
