Two-direction multiscaling functions φ and two-direction multiwaveletsψ associated with φ are more general and more flexible setting than one-direction multiscaling functions and multiwavelets. In this paper, we investigate how to find and normalize point values and those of derivatives of the two-direction multiscaling functions φ and multiwavelets ψ. For finding point values, we investigate t...

A vertex with neighbours of degrees d1 ≥ · · · ≥ dr has vertex type (d1, . . . , dr). A graph is vertex-oblique if each vertex has a distinct vertex-type. While no graph can have distinct degrees, Schreyer, Walther and Mel’nikov [Vertex oblique graphs, same proceedings] have constructed infinite classes of super vertex-oblique graphs, where the degree-types of G are distinct even from the degre...

Background: In 1991, Wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. Originally, this procedure has been performed with silicone band expander. The aim of this study was to report the results of treatment of a series of patients with A-pattern strabismus associated with overacting superior oblique muscle using the fascia lata...
