We present improved techniques for finding homologous regions in DNA and protein sequences. Our approach focuses on the core regions of a local pairwise alignment; we suggest new ways to characterize these regions that allow marked improvements in both specificity and sensitivity over existing techniques for sequence alignment. For any such characterization, which we call a vector seed, we give...
Specimens collected from the forest areas of Mazandaran Province (Iran), Kojour, between Lashkenareh and Gandis-Kala village showed significant characteristics. At first glance, these specimens looked similar to A. szowitsianum, but with no indumentum on fruit. Further studies showed that those specimens belong to a new species, Alyssum mazandaranicum Mirzadeh & Assadi sp. nov., wh...
We propose a modified nonparametric Baumgartner-Weiβ-Schindler test and investigate its use in testing for trends among K binomial populations. Exact conditional and unconditional approaches to p-value calculation are explored in conjunction with the statistic in addition to a similar test statistic proposed by Neuhäuser (2006), the unconditional approaches considered including the maximization...
