In this paper, we investigate duality of modular g-Riesz bases and g-Riesz bases in Hilbert C*-modules. First we give some characterization of g-Riesz bases in Hilbert C*-modules, by using properties of operator theory. Next, we characterize the duals of a given g-Riesz basis in Hilbert C*-module. In addition, we obtain sufficient and necessary condition for a dual of a g-Riesz basis to be agai...

A group of agents have claims on a resource, but there is not enough of it to honor all of the claims. How should it be divided? A group of agents decide to undertake a public project that they can jointly afford. How much should each of them contribute? This essay is an update of Thomson (2003), a survey of the literature devoted to the study of such problems. JEL classification number: C79; D...

We investigate the norm of sums of independent vector-valued random variables in noncommutative Lp spaces. This allows us to obtain a uniform family of complete embeddings of the Schatten class S q in Sp(lmq ) with optimal order m ∼ n. Using these embeddings we show the surprising fact that the sharp type (cotype) index in the sense of operator spaces for Lp[0, 1] is min(p, p) (max(p, p)). Simi...

This research in progress is part of a study being submitted for dissertation. The purpose of this study is to determine what types of students will be impacted by Classroom Response Systems (CRS) technology. Additionally, this research explores the nature of the outcomes experienced by students and their perceptions of leading pedagogy and practices for CRS technology in the classroom. An exte...

W e present detai led experimental results concerning the temperature and concentration dependence of the 2 0 9 B i K n i g h t shift and the N M R l inewidth in l iquid B i N i . The measurements are carried out in a n external magnetic field of about 39 K G over the concentration range (0—35) a t . % N i a t temperatures f rom 400 K to 1300 K . According to our experimental results there are ...

let $g$ be a non-abelian group and let $z(g)$ be the center of $g$. associate with $g$ there is agraph $gamma_g$ as follows: take $gsetminus z(g)$ as vertices of$gamma_g$ and joint two distinct vertices $x$ and $y$ whenever$yxneq yx$. $gamma_g$ is called the non-commuting graph of $g$. in recent years many interesting works have been done in non-commutative graph of groups. computing the clique...

we present detailed theoretical studies of the h-bonded complexes formed from interaction between 5-fluorouracil and various six-membered cyclic nitrosamine compounds. in this study, an investigation on intermolecular interactions in x-nu (x = ch2, sih2,bh, alh, nh, ph, o and s) complexes is carried out using density functional theory. the calculations are conducted on b3lyp/6-311++‏‏g** level ...

stabilizations and atomic level quadrupole coupling constant (cq) properties have been investigated for graphene–like monolayers (g–monolayers) of boron nitride (bn), boron phosphide (bp), aluminum nitride (aln), and aluminum phosphide (alp) structures. to this aim, density functional theory (dft) calculations have been performed to optimize the model structures and also to evaluate the cq para...

The ACELP method makes use of multipulse structure to represent the excitation pulses of residual signal. With the purpose of computational complexity reduction, this paper provides the Maximum-TakePrecedence ACELP (MTP-ACELP) search method under the acceptable degradation in performance. Because the maximum of target signal is preferentially compensated, the degradation of performance would be...
