The complex [PtMe2({κ(2)-N,N-RN[double bond, length as m-dash]CH-2-C5H4N})] reacts with oxygen in acetone solution to give the platinum(iv) complex [Pt(OH)Me2{κ(3)-N,N,O-RNH-CH(2-C5H4N)(CH[double bond, length as m-dash]CMeO)}], when R = 2-C6H4OH, but not when R = Ph. It has been suggested that the phenol substituent plays two key biomimetic roles; firstly, in proton coupled electron transfer re...

1. The inaccurate Figs. 1–4 should be replaced with a table (Table 1). The reason is that the optimal performance for the M-, R-, and 3P-managed models is so close to each other numerically, and the subtle difference was not illustrated in the figures. However, Table 1 in this erratum shows the actual difference and is more helpful in understanding Corollaries 1–3. 2. Secondly, the more accurat...

evaluate the performance of companies on the stock exchange using non-parametric methods is very important. dea and dea-r with the strategies for piecewise linear frontier production function and use of available data, assess the stock company. in this study, using a neural network algorithm dea and dea-r is suggested to classify the first companies in the stock exchange; secondly, using the co...

A new approach to counterexamples to A new approach to counterexamples to L The derivation of counterexamples to L 1 estimates can be reduced to a geometric decomposition procedure along rank-one lines in matrix space. We illustrate this concept in two concrete applications. Firstly, we recover a celebrated, and rather complex, counterexample by Ornstein, proving the failure of Korn's inequalit...

In recent works, we have studied linear predictive models constrained by time-domain filters. In the present study, we will study the one-dimensional case in more detail. Firstly, we obtain root-exchange properties between the roots of an all-pole model and corresponding constraints. Secondly, using the root-exchange property we can construct a novel matrix decomposition A RA = I, where R is a ...

A 68-year-old male patient was referred because of an irregular heart rhythm. The electrocardiogram (Fig. 1) showed sinus bradycardia with interpolated premature ventricular complexes (PVCs) occurring in a trigeminal pattern. There are two interesting observations in Figure 1. First, there is an alternating pattern of P-P intervals, with intervals of 1,320–1,340 ms whenever there is a PVC betwe...

We derive and analyse a deterministic model for the transmission of malaria disease with drug resistance in the infectives. Firstly, we calculate the basic reproduction number, R, and investigate the existence and stability of equilibria. The system is found to exhibit backward bifurcation, with this occurrence, the classical epidemiological requirement for effective eradication of malaria, R <...

immunohistochemical demonstration of tumor-associated markers may be valuable as an adjunct to conventional histology for determination of malignancy development in oral mucosal diseases. accordingly, the present study determined the distribution of some important tumor markers such as heat shock proteins (hsp), fibroblast growth factors (fgf) and transferrin receptors (tf-r) in 22 samples of p...

In this paper we develop an analog of the notion of the con- jugacy graph of  nite groups for the  nite semigroups by considering the Green relations of a  nite semigroup. More precisely, by de ning the new graphs $Gamma_{L}(S)$, $Gamma_{H}(S)$, $Gamma_{J}(S)$ and $Gamma_{D}(S)$ (we name them the Green graphs) related to the Green relations L R J H and D of a  nite semigroup S , we  first atte...

An analogy between abelian Anderson T-motives of rank r and dimension n , and abelian varieties over C with multiplication by an imaginary quadratic field K, of dimension r and of signature (n, r − n), permits us to get two elementary results in the theory of abelian varieties. Firstly, we can associate to this abelian variety a (roughly speaking) K-vector space of dimension r in C. Secondly, i...
