In this study, phylogenetic relationships and evolutionary trends of morphological characters of Astragalus sects. Acanthophace and Aegacantha were studied using nrDNA ITS and rpl32-trnLUAG datasets while Astragalus stocksii was selected as the outgroup. The phylogenetic results indicated the non-monophyly of A. sect. Acanthophace in its current circumscription due to the distant exclusion of A...
Seven species of Marasmius sect. Globulares with smooth pileipellis cells (sect. Globulares s. Singer) have been collected in the Republic of Korea (South Korea) to date, viz. M. aurantioferrugineus, M. brunneospermus, M. maximus, M. nivicola, M. purpureostriatus, M. wynneae and M. fusicystidiosus. Descriptions of their macro- and microscopic features with a discussion of similar taxa are given...
Christiansen & Chater (C&C)'s key premise is that "if linguistic information is not processed rapidly, that information is lost for good" (sect. 1, para. 1). From this "Now-or-Never bottleneck" (NNB), C&C derive "wide-reaching and fundamental implications for language processing, acquisition and change as well as for the structure of language itself" (sect. 2, para. 10). We question both the pr...
گونه Agrostis gariana به عنوان آرایهای جدید از لرستان در ایران معرفی میشود که خویشاوند نزدیک A. canina از بخش Sect. Agraulus است. گونه دیگری از بخش Sect. Agraulusبا نام A. vinealis که از عناصر ایران و تورانی است برای اولین بار از ایران گزارش میشود. این گونهها با نزدیک ترین گونههای خویشاوند خود مقایسه شده و تصویر و اطلاعات پراکنش جغرافیایی آنها ارائه میشود
section gamosepalum has been reported from turkey for the first time by dudley. in recent years, several species of this section were reported as new records for iran. four species of alyssum section are tranfered from sect. alyssum to sect. gamosepalum with considering of important characters in each section. these changes made two synonymies. five species of gamosepalum section including a. l...
Self-organization in the sense used in natural sciences means the spontaneous creation of patterns in space and/or time in dissipative systems consisting of many individual components. Central in this context is the notion of emergence meaning the spontaneous creation of structures or functions that are not directly explainable from the interactions between the constituents of the system. This ...
The present study aimed at elucidating the structure of Inocybe subg. Inosperma sect. Rimosae but included also representatives from subg. Mallocybe and the genus Auritella. Phylogenetic relationships were inferred using ITS, LSU and mtSSU sequence data. The analyses recovered the ingroup as a monophyletic, strongly supported clade. The results indicate that recognizing Auritella on the genus l...
In the Semantic Web Service Challenge (SWSC), several international groups analyze how semantic web techniques can help to overcome interoperability issues of existing system [5] on the basis of concrete scenarios and with discussion and comparison of approaches and solutions [9]. Our group, representing the Center of Innovation on Service Centered Continuous Engineering (SCCE), addresses this ...
This article describes abductions as special patterns of inference to the best explanation whose structure determines a particularly promising abductive conjecture (conclusion) and thus serves as an abductive search strategy (Sect. 1). A classification of different patterns of abduction is provided which intends to be as complete as possible (Sect. 2). An important distinction is that between s...
Nonnegative Matrix Factorization has been proved to be valuable in many fields of data mining, especially in unsupervised learning. In this paper, we will briefly review its variations and applications in image processing, data clustering, semi-supervised clustering, bi-clustering (co-clustering) and financial data mining. Note that we cannot cover all the interesting works on NMF, but generall...
