Restriction site maps of chloroplast DNA (cpDNA), maternally inherited in Clarkia, were obtained in representative species of all seven diploid sections, the allotetraploid sect. Clarkia, and the outgroup Epilobium brachycarpum. CpDNA restriction site variation was analyzed by Wagner and Dollo parsimony, bootstrapping, and genetic distance methods. Four shortest Wagner trees, one of which was a...

We propose a graphic method to derive the classical algebra (Dirac brackets) of non-local conserved charges in the two-dimensional supersymmetric non-linear O(N) sigma model. As in the purely bosonic theory we find a cubic Yangian algebra. We also consider the extension of graphic methods to other integrable theories. 1 Introduction Non-linear sigma models [1-3] are prototypes of a remarkable c...

The Praguian approach to formal description of language (in detail, see Sgall et aI. 1986), works with dependency syntax and includes the topicfocus articulation into the (underlying, tectogrammatical) syntactic representations of sentences, using the left-to-right order of the nodes of the dependency tree for that purpose. The edges of the tree denote the dependency relations and the nodes car...

Background: Thrombolysis (tPA) and endovascular thrombectomy (EVT) are interventions for acute ischemic stroke (AIS) that can be accompanied by intracerebral hemorrhage (ICH), which alter the patient’s management, or contrast extravasation (CE), is relatively benign. Previous retrospective studies have shown dual-energy CT (DECT) significantly more accurate differentiating ICH from CE compared ...
