Understanding the numerous functions that RNAs play in living cells depends critically on knowledge of their three-dimensional structure. Due to the difficulties in experimentally assessing structures of large RNAs, there is currently great demand for new high-resolution structure prediction methods. We present the novel method for the fully automated prediction of RNA 3D structures from a user...

An element is non-composite but composes other particles. The elementary quarks & leptons of the Modern Standard Model are found to be compressible and assembleable, hence having composition. These in Unified Theory are composed by two elementary cosminos, positrino & negatrino. The cosmino-sharmon composition-structures of electron, proton and neutron presented for the first time are defined b...

Understanding the organization of eukaryotic centromeres has both fundamental and applied importance because of their roles in chromosome segregation, karyotypic stability, and artificial chromosome-based cloning and expression vectors. Using clone-by-clone sequencing methodology, we obtained the complete genomic sequence of the centromeric region of rice (Oryza sativa) chromosome 8. Analysis o...

In this paper we present the evolution of the structure of the Chilean Web between 2000 and 2002. Our results show that although the Web grows as expected, also a significant part of it disappears. In addition, some components are much more stable than others. We also compare the expected life cycle of a Web site in the structure with the actual real data.

Crustaceans have a rigid exoskeleton, which is made of a layered cuticle, covering the soft body parts for protection from conspecific competitors and/or interspecific predators. Calcium carbonate adds rigidity to the crustacean cuticle, which consequently means that growth only occur at each molt. The current study presents a review of existing literature on crustacean exoskeleton cuticle phys...

1. The preparation of isolated chromosomes from liver, kidney, and pancreas has been described. 2. It has been shown that there is no gross cytoplasmic contamination in these preparations. 3. In a microscopic study of isolated chromosomes the same chromosomes have been found in different tissues of the same organism. Since individuality is one of the main characteristics of chromosomes, there c...

Improving dynamic feature of service composition is a vital and challenging stage in web service application. With the increasing of service number, it is hard to balance the flexibility and verification very well in dynamic and complex environment. The previous methods compare two services by their own features. These methods are useful and concise to find substitutes for unavailable services,...

This paper discusses the problem of learning language from unprocessed text and speech signals, concentrating on the problem of learning a lexicon. In particular, it argues for a representation of language in which linguistic parameters like words are built by perturbing a composition of existing parameters. The power of this representation is demonstrated by several examples in text segmentati...
