Electron microprobe analyses of platform (pectiniform Pa) elements of Permian conodonts reveal detailed and systematic chemical element distributions. The crown of the conodont element is more densely mineralized than the basal body and shows evidence of less dense mineralization in areas of rapid growth. Patterns in sodium and sulfur concentrations indicate oral to aboral differentiation within conodont elements. These chemical element patterns support oral exposure during life and functional use as a tooth, and they approximate the erupted and embedded positions of the conodont tooth when th

Abstract Six copies of the mariner element from the genomes of Drosophila mauritiana and Drosophila simulans were chosen at random for DNA sequencing and functional analysis and compared with the highly active element Mos1 and the inactive element peach. All elements were 1286 base pairs in length, but among them there were 18 nucleotide differences. As assayed in Drosophila melanogaster, three of the elements were apparently nonfunctional, two were marginally functional, and one had moderate activity that could be greatly increased depending on the position of the element in the genome.

The DNA replication origins of the yeast Saccharomyces cerevisiae require several short functional elements, most of which are not conserved in sequence. To better characterize ARS305, a replicator from a chromosomal origin, we swapped functional DNA elements of ARS305 with defined elements of ARS1. ARS305 contains elements that are functionally exchangeable with ARS1 A and B1 elements, which are known to bind the origin recognition complex; however, the ARS1 A element differs in that it does not require a 3' box adjacent to the essential autonomously replicating sequence consensus.

Abstract Despite the abundance of Ty1 RNA in Saccharomyces cerevisiae, Ty1 retrotransposition is a rare event. To determine whether transpositional dormancy is the result of defective Ty1 elements, functional and defective alleles of the retrotransposon in the yeast genome were quantitated. Genomic Ty1 elements were isolated by gap repair-mediated recombination of pGTy1-H3(delta 475-3944) HIS3, a multicopy plasmid containing a GAL1/Ty1-H3 fusion element lacking most of the gag domain (TYA) and the protease (PR) and integrase (IN) domains.

Carbon materials are one of the most fascinating materials because of their unique properties and potential use in several applications. They can be obtained from agricultural waste, organic polymers, or by using advanced synthesizing technologies. The carbon family is very wide, it includes classical activated carbons to more advanced types like carbon gels, graphene, and so on. The surface chemistry of these materials is one of the most interesting aspects to be studied.

A permutation phrase is a sequence of elements (possibly of different types) in which each element occurs exactly once and the order is irrelevant. Some of the permutable elements may be optional. We show how to extend a parser combinator library with support for parsing such free-order constructs. A user of the library can easily write parsers for permutation phrases and does not need to care about checking and reordering the recognized elements. Applications include the generation of parsers for attributes of XML tags and Haskell's record syntax.

Although the yeast his3 promoter region contains two functional TATA elements, TR and TC, the GCN4 and GAL4 upstream activator proteins stimulate transcription only through TR. In combination with GAL4, an oligonucleotide containing the sequence TATAAA is fully sufficient for TR function, whereas almost all single-base-pair substitutions of this sequence abolish the ability of this element to activate transcription. Further analysis of these and other mutations of the TR element led to the following conclusions. First, sequences downstream of the TATAAA sequence are important for TR function.

Abstract The white-peach allele in Drosophila results from insertion of the transposable element mariner. The particular copy that is inserted in white-peach is an inactive copy referred to as the peach element. The peach element is excised at a high rate in the presence of active copies of mariner located elsewhere in the genome, and the excision of peach in somatic cells is recognized phenotypically by the occurrence of eye-color mosaicism in white-peach flies. Active mariner elements identified by their ability to induce high levels of white-peach mosaicism are denoted Mos (Mosaic) factors.

Abstract Hermes is a short inverted repeat-type transposable element from the house fly, Musca domestica. Using an extra-chromosomal transpositional recombination assay, we show that Hermes elements can accurately transpose in M. domestica embryos. To test the ability of Hermes to function in species distantly related to M. domestica we used a nonautonomous Hermes element containing the Drosophila melanogaster white (w +) gene and created D. melanogaster germline transformants. Transgenic G1, insects were recovered from 34.6% of the fertile Go adults developing from microinjected w − embryos.

It has previously been shown that the combination of two deleted P elements in trans, one containing the left functional end and the second element the right functional end, can lead to high levels of male recombination. This finding strongly suggests that P-element, ends from different chromosomes can become associated, followed by “pseudo-excision.” We show that two different processes are involved in resolving the pseudo-excision event: (1) the excised P-element ends continue to function as a single unit (Hybrid Element) and insert at a nearby site in the chromosome or into the element itse

AbstractThe aim of this paper is to provide a new perspective on finite element accuracy. Starting from a geometrical reading of the Bramble–Hilbert lemma, we recall the two probabilistic laws we got in previous works that estimate the relative accuracy, considered as a random variable, between two finite elements {P_{k}} and {P_{m}} ({k<m}). Then we analyze the asymptotic relation between these two probabilistic laws when the difference {m-k} goes to infinity. New insights which qualify the relative accuracy in the case of high order finite elements are also obtained.

Generalised stacking fault energies of copper alloys have been calculated using density functional theory. Stacking fault energy of copper alloys is correlated with the d?electrons number of transition metal alloying element. The tendency to twiningis also modified by the presence of alloying element in the deformation plane. The results suggest that Cu ?transition metal alloys with such elements as Cr, Mo, W, Mn, Re are expected to exhibit great work hardening rate due to the tendency to emission of the partial dislocations.

The yeast his3 promoter region contains two TATA elements, TC and TR, that are differentially utilized in constitutive his3 transcription and Gcn4-activated his3 transcription. TR contains the canonical TATAAA sequence, whereas TC is an extended region that lacks a conventional TATA sequence and does not support transcription in vitro. Surprisingly, differential his3 TATA-element utilization does not depend on specific properties of activator proteins but, rather, is determined by the overall level of his3 transcription.

ABSTRACT The structure of replication origins in metazoans is only nominally similar to that in model organisms, such as Saccharomyces cerevisiae. By contrast to the compact origins of budding yeast, in metazoans multiple elements act as replication start sites or control replication efficiency. We first reported that replication forks diverge from an origin 5′ to the human c-myc gene and that a 2.4-kb core fragment of the origin displays autonomous replicating sequence activity in plasmids and replicator activity at an ectopic chromosomal site. Here we have used clonal HeLa cell lines contain

Replicators that control the initiation of DNA replication in the chromosomes of Saccharomyces cerevisiae retain their function when cloned into plasmids, where they are commonly referred to as autonomously replicating sequences (ARSs). Previous studies of the structure of ARS1 in both plasmid and chromosome contexts have shown that it contains one essential DNA element, A, that includes a match to the ARS consensus sequence (ACS), and three additional elements, B1, B2, and B3, that are also important for ARS function. Elements A and B3 are bound by a candidate initiator protein called the ori

This paper points out that certain frequently used terms in linguistic literature, such as“prominent/salient” and “background/ground”, are in fact interpreted differently or even contrarily in Functional Grammar and Cognitive Grammar. The paper attributes their diversified interpretations to the fundamental differences between these two linguistic schools in terms of paradigm and methodology, i.e. to focus on communicative activities of speech and discourse rules or on cognitive abilities and rules. The paper claims that “prominence” as a concept in cognitive grammar mainly relates to the spea

The researchers’ interest in the setting and especially the element of place in the novel has long been discussed in relation to narrative discourse. The significance of place has surpassed its importance as an element of the plot to its connotative implications. Narrative space goes beyond a mere description of the surrounding setting to create polarities in relation to other harmonious elements. Juri Lotman refers to this relationship between literary space and other narrative elements as spatial polarity. Spatial polarity cannot be realized in isolation from other narrative elements such as

abstract: Assuming that features on functional heads are variables (Borer 2005), we expect to find syntactic operations and functional elements that target and manipulate these variables beyond matching and valuation in agree. We argue that such syntactic operations and functional elements exist. This paper presents such a functional element: a polarity operator manipulating features of a nominal functional head it modifies. The empirical motivation for our proposal comes from parallel systematic homophony over the same set of functional interpretations and features within the nominal extended

This paper discusses an approach to finite element modelling of structure elements considering material inhomogeneity. This approach is based on the functional dependence of mechanical properties on the spatial coordinates of finite elements. It allows modelling gradient transitions between different materials, which avoid stress discontinuities during strength analysis. The finite element models of cold formed angle, welded joint and thermal barrier coating, created by this method, have been presented.

We have determined that two P elements, P[21-3] and P[21r36], residing in the 5′-UTR of the vestigial wing gene, encode functional repressors in eye tissue. However, neither element fits a previous categorization of repressor-making elements as Type I or II. Both elements encode polypeptides that are shorter than the canonical elements they most closely resemble. DNA sequencing reveals that P[21r36] encodes an intact THAP domain that is missing in the P[21] element, which does not encode a functional repressor. Recovery of P[21-3] at sites other than vestigial (where it causes the wing mutant,

In this paper, we argue against the view that prepositions designate motion. We make the case for prepositions such as to and through being associated with spatial properties in addition to a functional element. The functional element arises as a consequence of our daily interaction with the spatial configuration associated with the particular preposition. While to is associated with a spatial configuration in which a TR is oriented in the direction of a LM, its functional element is that of the LM constituting the TR’s goal.

A chimeric protein consisting of Deformed with a substituted Abdominal-B homeodomain (Dfd/Abd-B) is used to identify protein domains outside the homeodomain that are required for regulatory activity in vivo. A series of deletion proteins were generated based on regions showing amino acid composition similar to known regulatory domains. Each mutant protein can influence regulation of homeotic genes in a manner distinct from the intact protein. Activity was also tested using promoter elements from empty spiracles and Distal-less, two genes known to be directly regulated by Abdominal-B. Removal o
