The recently introduced twin-width of a graph \(G\) is the minimum integer \(d\) such that has \(d\)-contraction sequence, is, sequence \(\left| V(G) \right|-1\) iterated vertex identifications for which overall maximum number red edges incident to single at most \(d\), where edge appears between two sets identified vertices if they are not homogeneous in (not fully adjacent nor non-adjacent). ...

introduction: the different factors that affect the camera uniformity of single photon emission computed tomography (spect) technique have been analyzed including peak shift (%) and window width of energy. the effect of peak shift and window width on spect image uniformity has been investigated using a point source to perform intrinsic flood images. methods:the relation between calculated integ...

background: the aim of this study was to determine the pattern and amount of change exhibited in mandibular intercanine and intermolar width during treatment and assessing its stability1-3 years post-retention. materials and methods: the material consisted of 70 cases of which 20 cases were treated without extraction and 30 cases were treated with extraction, which were compared with 20 untreat...

We consider the graph parameter boolean-width, related to the number of different unions of neighborhoods across a cut of a graph. Boolean-width is similar to rankwidth, which is related to the number of GF [2]-sums (1+1=0) of neighborhoods instead of the Boolean-sums (1+1=1) used for boolean-width. It compares well to the other four well-known width parameters tree-width, branch-width, clique-...

size at sexual maturity and patterns of somatic growth are important aspects of reproductive history of crab. the main purpose of this study is to provide an estimate for the onset of morphological sexual maturity in mangrove crab, opusia indica from a population located in korangi creek intertidal mud flat (karachi, pakistan) based on relative growth. the crabs were monthly collected through q...
