“Phases in a general chaotic three-coupled-laser array are numerically investigated. Phase attractors are firstly found to exist within corresponding basins of attraction

on the projection plane of phase differences of the three-coupled-laser array. Whether the chaos appears or not is related not only to the coupling strength but also to PB 203580 the initial phase differences. For a large coupling strength new phase attractors can occur. With the increase of coupling strength, the three-coupled-laser array has a great chance of resulting in a quiescent to chaotic state. Based on these results, we present the method to reach phase-locking when the coupling strength is strong.”
“The rudist bivalve genus Gorjanovicia Polsak, 1967 from Istria, Croatia, is currently known from the Coniacian/Maastrichtian of the peri-Adriatic and Balkan regions and includes 23 nominal species, defined mainly on shell ornamentation and radial bands. However, a re-appraisal of ‘Radiolites’endrissi Boehm, 1927 shows the type species of the genus Gorjanovicia, G. costata Polsak, FDA-approved Drug Library price 1967, to be a junior synonym of Boehm’s species, which thus takes priority as the type species of Gorjanovicia. Our revision of the 24 species thus described from the literature is based on analysis of a set of 21 characters

that include the dimensions, shape and ornamentation of the right valve. Sixteen variables are defined from combinations of these 21 characters and subjected to multiple correspondence analysis (MCA) and Hill and

Smith analysis (HSA), with cluster analysis, which has allowed us to distinguish three taxonomic groups, each defined by a key species: Gorjanovicia endrissi (Boehm), selleck G. ugarensis Sliskovic and G. kvarneri Polsak. Cluster analysis identifies three groups of associated variables and suggests that a limited number of characters may be used to recognize the foregoing three taxonomic entities. MCA performed on four variables (the shapes of the anterior radial band, posterior radial band and interband and the width of the anterior band relative to the posterior band) reveals the same three taxonomic groups as in the MCA based on 16 variables. We conclude that the four variables in question may thus be used as specific diagnostic characters and that the genus Gorjanovicia is thereby represented by just three species, Gorjanovicia endrissi, G. ugarensis and G. kvarneri, instead of the 24 described in the literature. Specific assemblages from the peri-Adriatic, pre-Apulian and Western Pontides regions are nearly identical, a pattern that suggests free faunal exchanges within the distributional area of the genus Gorjanovicia. The palaeobiogeographical distribution of species corresponds with a relatively narrow palaeolatitudinal range in the subtropical portion of the eastern Mediterranean Tethys.
