In the early seventies, Barbara Partee suggested that tenses in natural languages mi ght not be operators, but pronouns. Like pronouns, they have indexical, anaphoric, and bound variable uses. In this short presentation, I wil l discuss one more parallel between tenses and pronouns. S ometimes

transcripts (pri-miRNAs) by the ribonuclease Drosha and further cytoplasmic processing of pre-miRNAs by the ribonuclease Dicer. This review discusses the issue of miRNA end heterogeneity generated primarily by Drosha and Dicer cleavage and focuses on the structural aspects of the Dicer step of mi

genome for potential miRNA targets. The screening procedure combines a sequence search with an evaluation of the predicted miRNA–target heteroduplex structures and energies. We show that this approach successfully identifies the five previously validated let-7, lin-4, and bantam targets from a large

Abstract-This paper deals with an electronics developed for controlling of contactless current sensor based on magnetoimpedance (MI) effect. The demands required on design of the electronics came from current sensor structure, which takes into account suppression of temperature dependences

-GTP cofactor. Here, we have examined the structural requirements for pre-microRNA binding by Exp5. Our data indicate that pre-miR-30 binding requires an RNA stem of.16 bp and is facilitated by a 30 overhang. Although a blunt-ended derivative of the pre-miR-30 stem–loop remained capable of binding Exp5, 50 over

-authors requested Web pages using a heuristic planning algorithm and a set of structural page transformations to achieve the best looking document for a given display size. 1. Introduction Access to World-Wide Web documents from personal electronic devices has been demonstrated in research projects [2

and structure. At the same time a need for design guidelines for the use of FRC-materials has been widely recognized both by researchers and practical engineers. Design guidelines based on a simple material classification as well as representation of (mechanical) material properties can be considered as a pre

, and Nanog. miRNAs are unlike other small noncoding RNAs in their biogenesis, since they derive from precursors that fold back to form a distinctive hairpin structure, whereas other classes of small RNAs are formed from longer hairpins or bimolecular RNA duplexes (siRNAs) or precursors without double

, which are compositionally similar, except hat the smectite is slightly richer in SiO2 and MgO and poorer in Fe203 than the vermiculite. To establish a structural formula for the ferruginous mectite, the oxidation state of Fe in a sample treated with dithionite-citrate-bicarbonate was examined

This paper deals with the stress and temperature induced microstructure transformations in a soft bearing steel 100Cr6 after turning operation. Investigation is carried out through a technique based on Barkhausen effect. Evaluation of surface integrity via structure transformations, X
