Introduction to Computational Biology Lecture # 32: RNA secondary structure predication

Today we are going to learn about prediction of RNA folding. RNA is a polymer of four types of nucleotides subunits ACGU. C-G and A-U form hydrogen bonded base pairs, and are said to be complementary. G-C pairs form three hydrogen bonds and tend to be more stable than the A-U pairs, which form only two. In addition to the canonical A-U and G-C pairs, non canonical pairs can also occur in RNA se...

Secondary Predication in L2 Grammar

A persistent question in the SLA (second language acquisition) research concerns the status of the involvement of the native language (i.e. L1 transfer). Inquiry into the question has been made on the basis of a variety of linguistic frameworks, such as contrastive analysis (Lado, 1957), L2 (second language) generative parametric approach (Flynn, 1987; White, 1989; Schwartz, 1996), and the more...

Secondary predication and instrumental case in Russian

occur in many languages. The phenomenon in English was called secondary predica t ion . The intuitive understanding of (1) seems clear, but already in English it is not clear which phenomena are to be called secondary predication in general. Things get even more difficult when other languages are considered. The problem is not merely one of the term extension. The emphasis is on the relation be...

Information structure and aspectual competition

The imperfective aspect in Russian competes with the perfective in referring to events whose existence is entailed by the input context. In the first, major part of the paper (sections 1-5) I take a global view on aspectual competition, which is analyzed in light of various pragmatic constraints. It is shown in a bidirectional optimization how the default/unmarked imperfective in the appropriat...
