In the gal-his3 hybrid promoter, his3-GG1, GCN4 stimulates transcription at the position normally occupied by a TATA element. This expression requires two elements within gal1-10 sequences, a REB1-binding site and a second element, Z, which resides 20 base pairs upstream of the GCN4-binding site. No obvious TATA element is present in this promoter. To characterize the function of Z, we replaced...
We combine old and new quantum field theoretic arguments to show that any theory of stable or metastable higher spin particles can be coupled gravity only when the sector has a stringy structure. Metastable particles, free interacting, cannot couple while preserving causality unless there exist states in gravitational much below Planck scale $M_{\rm pl}$. obtain an upper bound on mass $\Lambda_...
In the gal-his3 hybrid promoter his3-GG1, the yeast upstream activator protein GCN4 stimulates transcription when bound at the position normally occupied by the TATA element. This TATA-independent activation by GCN4 requires two additional elements in the gal enhancer region that are distinct from those involved in normal galactose induction. Both additional elements appear to be functionally d...
FT-IR and Raman spectra of 1-heptylamine (1-ha) have been recorded in the region of 4000-10 cm(-1) and 4000-50 cm(-1), respectively. The conformational analysis, optimized geometric parameters, normal mode frequencies and corresponding vibrational assignments of 1-ha (C7H17N) have been examined by means of the Becke-3-Lee-Yang-Parr (B3LYP) density functional theory (DFT) method together with th...
Y-chromosomal haplogroup G1 is a minor component of the overall gene pool of South-West and Central Asia but reaches up to 80% frequency in some populations scattered within this area. We have genotyped the G1-defining marker M285 in 27 Eurasian populations (n= 5,346), analyzed 367 M285-positive samples using 17 Y-STRs, and sequenced ~11 Mb of the Y-chromosome in 20 of these samples to an avera...
Abstract A semi-Lagrangian relativistic Vlasov–Maxwell solver is used to describe the non-linear momentum transfer between electron beams, which driven by spontaneous fluctuations in oblique filamentation instability (a type of Weibel mode) two-dimensional plasmas. For counter-streaming plasmas, these instabilities may strengthen generation a fine structure distribution function phase space. Pr...
We developed an analytic theory of inhomogeneous superconducting pairing in strongly disordered materials, which are moderately close to superconducting-insulator transition. Single-electron eigenstates assumed be Anderson-localized, with a large localization volume. Superconductivity develops due coherent delocalization originally localized pre-formed Cooper pairs. The key assumption the is th...
OBJECTIVE To estimate the seroprevalence of HSV-1 and HSV-2 antibodies in Brazil and to analyze factors associated. METHODS Cross-sectional study including subjects aged 1-40 years from the general population in four different geographical areas in Brazil between 1996 and 1997. All subjects were stratified by age and gender and 1,090 of them were included in the final analysis. Blood samples ...
Observations indicate that turbulence in the interstellar medium (ISM) is supersonic ($M_{\rm turb}\gg1$) and strongly magnetized ($\beta\sim0.01-1$), while intracluster (ICM) it subsonic turb}\lesssim1$) weakly ($\beta\sim100$). Here, $M_{\rm turb}$ turbulent Mach number $\beta$ plasma beta. We study properties of shocks induced these disparate environments, including distribution shock number...
Introduction. The rice cultivar INCA LP-7 is one of the eleven principal cultivars in Cuba due to their high yield potential, salinity tolerance, and pathogens resistance. However, there are not reports about isolation, identification, characterization bacteria associated this that promote its growth. Objective. To select promising from rhizosphere crop Materials methods. investigation was carr...
