    Helicobacter pylori strains show both geographic and disease-associated allelic variation. We investigated the diversity present in two genes, babA and babB, which are members of a paralogous family of outer membrane proteins. Eleven family members within a single H. pylori strain, predicted to encode proteins with substantial N- and C-terminal similarity to each other, were classified as babA paralogues. In their central regions, most are less than 54 % related to one another. Examining the babA and babB central regions in 42 H. pylori strains from different geographic locales, we identified five different allele groups of babA (AD1 to AD5) and three different allele groups of babB (BD1 to BD3). Phylogenetic analysis revealed that the allelic groupings of babA and babB are independent of one another and that, for both, geographic variation is present. Analysis of synonymous and nonsynonymous substitutions in these regions showed that babA is more diverse, implying an earlier origin than that of the same region of babB, but that the babA diversity region may have more functional constraints. Although recombination has been central to the evolution of both genes, with babA and babB showing low mean compatibility scores and homoplasy ratios of 0.71 and 0.67, respectively, recombination is not sufficient to obscure evidence of clonal descent. Despite the involvement of babA in binding to the host blood group antigen Lewis B, neither the presence of different babA allele groups nor that of different babB allele groups is a determining factor in Lewis B binding of H. pylori strains

    Savannah Not Place For Pan Finals

    John Babb reviews Category C finals of the Steelbands' Music Festival held at the Grand Stand, Queen's Park Savannah. Babb states that it was unfortunate that bands had to compete in such an atmosphere as the Savannah crowd proved difficult for Pan Trinbago officials to control and the expanse of the open air space made it difficult to accentuate the expressions of classical music. Results of Category C finals are provided

    <p>The representative structures of BabA and BabB are based on the J99 amino acid sequence, whereas the structure of BabC is based on the consensus sequence defined in this study. The N-HR indicates N-terminal homology region, M-VR indicates middle variable region, which is characterized by sequence difference among the three Bab proteins. Note that the M-VR is conserved for each of the Bab proteins. The C-HR indicates C-terminal homologous region that shows >90% identity. The CT-R present at the N-terminus of BabB refers to the CT repeat region. VR-1 and VR-2 in BabC indicate regions of variability among the BabC amino acid sequences analyzed in this study (n = 15).</p

    On the dirty plate trail remembering the Dust Bowl refugee camps

    No full text
    "The 1930s exodus of "Okies" dispossessed by repeated droughts and failed crop prices was a relatively brief interlude in the history of migrant agricultural labor. Yet it attracted wide attention through the publication of John Steinbeck's The Grapes of Wrath (1939) and the images of Farm Security Administration photographers such as Dorothea Lange and Arthur Rothstein. Ironically, their work risked sublimating the subjects-real people and actual experience-into aesthetic artifacts, icons of suffering, deprivation, and despair. Working for the Farm Security Administration in California's migrant labor camps in 1938-39, Sanora Babb, a young journalist and short story writer, together with her sister Dorothy, a gifted amateur photographer, entered the intimacy of the dispossessed farmers' lives as insiders, evidenced in the immediacy and accuracy of their writings and photosBorn in Oklahoma and raised on a dryland farm, the Babb sisters had unparalleled access to the day-by-day harsh reality of field labor and family life. This book presents a vivid, firsthand account of the Dust Bowl refugees, the migrant labor camps, and the growth of labor activism among Anglo and Mexican farm workers in California's agricultural valleys linked by the "Dirty Plate Trail" (Highway 99). It draws upon the detailed field notes that Sanora Babb wrote while in the camps, as well as on published articles and short stories about the migrant workers and an excerpt from her Dust Bowl novel, Whose Names Are Unknown. Like Sanora's writing, Dorothy's photos reveal an unmediated, personal encounter with the migrants, portraying the social and emotional realities of their actual living and working conditions, together with their efforts to organize and to seek temporary recreationAn authority in working-class literature and history, volume editor Douglas Wixson places the Babb sisters' work in relevant historical and social-political contexts, examining their role in reconfiguring the Dust Bowl exodus as a site of memory in the national consciousness. Focusing on the material conditions of everyday existence among the Dust Bowl refugees, the words and images of these two perceptive young women clearly show that, contrary to stereotype, the "Okies" were a widely diverse people, including not only Steinbeck's sharecropper "Joads" but also literate, independent farmers who, in the democracy of the FSA camps, found effective ways to rebuild lives and create communities."--Publisher descriptio

    This paper describes Complementary Code Keying with Differential Quadrature Phase Shift Keying (CCK+DQPSK) modulation, as used, for example, in the IEEE802.11b standard, and Gaussian Frequency Shift Keying (GFSK) modulation, as used, ofr example, in the Bluetooth standard. It indicates how the different types of modulation schemes might be more efficiently integrated to produce a modem capable of working with either modulation scheme. The paper presents a novel Multi Mode integrated Modem architecture, making use of: 1) programmable soft circuits 2) adaptive switching 3) adaptive FIR configuration 4) adaptive FIR functionality (same FIR, different function, e.g. correlation/matched filtering) 5) extended look-up table functionality Results are presented, indicating the performance of the integrated modem. Finally, implementation issues are discussed together with a way forward for further work in this area

    International financial institutions: forms, functions, and controversies

    No full text
    Having sizeable lending capacity and unparalleled epistemic power, international financial institutions (IFIs) are the world’s most powerful international organizations. One class of IFIs is primarily focused on lending for development projects, and commands portfolios of hundreds of millions of dollars that can transform infrastructure and social services in low- and middle-income countries. Another class is geared toward providing financial assistance to countries in economic crisis and has an active role in shaping their policy environments. Through these activities, IFIs alter the development trajectories of borrowing countries, for better or for worse. This article reviews these debates. We first map IFI forms and functions and examine their governance structures. Subsequently, we examine two of the leading controversies surrounding IFI activities: the problematic impact of these activities on social and environmental outcomes; and the charge that they impinge on developing countries’ policy sovereignty. We conclude by outlining fruitful directions for future research

    <p><b>A–B</b>: Left and right brain hemispheres from two mice (postnatal day 101). The left hemispheres of each animal were dehydrated with ethanol, or THF. The corresponding right hemispheres were dehydrated with ethanol as a control. Afterwards, the hemispheres were rendered transparent with BABB (A1 and B1. <b>C</b>: Left and right brain hemisphere of an exemplary mouse (postnatal day 101). The left hemisphere was dehydrated with THF and cleared with DBE. The right hemisphere was dehydrated with ethanol and then cleared with BABB as a control (C1). From all hemispheres 3D reconstruction were performed by UM (A2–C2, Olympus objective XLFluar 4×, N.A. 0.28). As evident from A–C, THF-dehydration provides an improved fluorescence signal (B2), and considerably reduced background fluorescence (B2), while DBE-clearing provides considerably better tissue transparency (C1) and strikingly better fluorescence preservation (C2). The black bars below A2–C2 represent intensity histograms of the respective image stacks used for 3D reconstruction. Length of scale bars in Figures A1–C1 is 2 mm. Scales are identical for all histograms A2–C2 and thus are only shown in the upper two histograms.</p

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
