We analyze a class of models for unequal crossover (UC) of sequences containing sections with repeated units that may differ in length. In these, the probability of an ‘imperfect’ alignment, in which the shorter sequence has d units without a partner in the longer one, scales like q as compared to ‘perfect’ alignments where all these copies are paired. The class is parameterized by this penalty...

Fig. 1 Let ABCD be a circumscribed quadrilateral, that is, a quadrilateral which has an incircle. Let this incircle have the centerO and the radius ρ and touch its sides AB, BC, CD, DA at the points X, Y, Z, W, respectively. Then, for some very obvious reasons, OX ⊥ AB, OY ⊥ BC, OZ ⊥ CD, OW ⊥ DA and OX = OY = OZ = OW = ρ. Moreover, AW = AX, BX = BY, CY = CZ, DZ = DW, since the two tangents from...

متن کاملCSE 573 Final Project: Semantic Labeling
Automatic image segmentation and semantic labeling is one of the most important and challenging problems in computer vision. Labeling could be done at various quantization levels – pixel level, super-pixel level, or group of superpixel (segment) level. Each approach has its advantages and disadvantages. In this paper, we explore the superpixel level semantic labeling of images using supervised ...
متن کاملSomatic antigen 2 inheritance in Salmonella groups B and D.
Somatic (O) antigen 2 of Salmonella paratyphi A replaced somatic antigen 4 of an S. typhimurium recipient as the consequence of mating with an S. paratyphi A var. durazzo Hfr strain. The genetic determinants of these O antigens behaved in this cross as alleles of a common O locus, which is linked to the determinant of histidine biosynthesis, his. By employing phage lysates obtained by growth of...
