The purpose of this paper is to propose an algorithm for solving the split common fixed point problems for total asymptotically strictly pseudocontractive mappings in infinite-dimensional Hilbert spaces. The results presented in the paper improve and extend some recent results of Moudafi 2011 and 2010 , Xu 2010 and 2006 , Censor and Segal 2009 , Censor et al. 2005 , Masad and Reich 2007 , Censo...

To the Editor: We read with great interest the article on human norovirus (hNoV) by Straub et al. (1). By using 3-dimensional aggregates of a highly differentiated intestinal epithelial cell line, the investigators claimed to have established an in vitro cell culture model that “support[s] the natural growth of human noroviruses.” While the authors provide compelling evidence of successful viru...

Perovskite oxides such as alkaline niobates crystal possess many interesting properties including piezoelectricity, pyroelectricity, electro-optic and nonlinear optical response (Bhalla et al., 2000). The most common alkaline niobates material is lithium niobate (LiNbO3). Since the discovery of LiNbO3 ferroelectricity (Matthias & Remeika, 1949), its properties are widely exploited by electronic...

The radial basis function (RBF) network is a popular artificial neural network (ANN) architecture that has found wide-ranging applications in many diverse fields of engineering, see for example, (Chen et al., 1990; Leonard & Kramer, 1991; Chen et al., 1993; Caiti & Parisini, 1994; Gorinevsky et al., 1996; Cha & Kassam, 1996; Rosenblum & Davis, 1996; Refaee et al., 1999; Muraki et al., 2001; Muk...

The mathematical basis of the hypothesis that type-2 topoisomerases (topo II) recognize and act at specific DNA juxtapositions was investigated by coarse-grained lattice and continuum wormlike chain models, showing that selective segment passages at hooked juxtapositions can result in dramatic reductions in catenane and knot populations. The lattice modeling approach has recently been extended ...

Cell culture provides a potentially useful system for studying carcinogenesis, but available systems of transformation in vitro have limitations. Permanent, non-tumorigenic mouse-embryo cell lines have been widely used, but were shown to form tumours when grown on solid supports and implanted into mice (Boone, 1976), and so may represent a pre-neoplastic rather than a normal state. The use of e...

Class III malocclusion remains one of the most challenging malocclusions for treatment and early or late treatment remains a subject of debate ( Campbell, 1983 ; Ngan, 2006 ; Ovsenik et al. , 2007 ). Baccetti et al. (2005) suggest that the most appropriate time is during the pre-pubertal growth period derived from cervical vertebral maturation criteria. Furthermore, if the optimal time is not o...

Moghaddam et al. (Moghaddam and Pentland, 1997) first proposed to perform object detection by modelling the marginal probability density function (pdf) of high dimensional features of appearance. Based on gaussian hypotheses, their approach is however not robust to outliers that can occur in images due, for instance, to cluttered backgrounds or partial occlusions. In (Dahyot et al., 2004), robu...

Heterotachy or variation of rates-across-sites and lineages is widespread (e.g., Fitch and Markowitz, 1970; Uzzel and Corbin, 1971; Lopez et al., 2002) and can cause biased tree estimation (Lockhart et al., 1998; Susko et al., 2004; Inagaki et al., 2004). Kolaczkowski and Thornton (2004) described an intriguing heterotachy model that lead to topological bias for likelihood-based methods. That w...
