This paper presents the findings of a research on the genus Isatis L.(Brassicaceae) in Iran. Isatis specimens kept in major herbaria of Iran were examined carefully. Fresh specimens were collected from Tehran, Mazandaran, Semnan, Hamedan, Kurdistan, W. Azarbaijan , E. Azarbaijan, Ardebil and Ghazvin provinces. Images of type or otherwise valid specimens kept in Viena, Munich, Montpollier and Ke...

This study explored the lytic ability of bacteriophages as a future tool for reducing the Salmonella spp.

In this paper, we study the representational properties of numeration systems. We argue that numeration systems are distributed representationsÑrepresentations that are distributed across the internal mind and the external environment. We analyze number representations at four levels: dimensionality, dimensional representations, bases, and symbol representations. The representational properties...

ÐThis paper presents a Similarity-Based Agglomerative Clustering (SBAC) algorithm that works well for data with mixed numeric and nominal features. A similarity measure, proposed by Goodall for biological taxonomy [15], that gives greater weight to uncommon feature value matches in similarity computations and makes no assumptions of the underlying distributions of the feature values, is adopted...

In this abstract we present ReTAX, a system for taxonomy revision in Botany. The function of ReTAX is to revise, and eventually modify, a taxonomic hierarchy as novel inconsistent data are provided. The system has been applied to replicate some taxonomic revisions which have taken place historically in the botanical family Ericaceae. As noted by different researchers (e.g., Lakatos, 1976; Kulka...
