Gene loss and lineage specific restriction-modification systems associated with niche differentiation in the Campylobacter jejuni Sequence Type 403 clonal complex
No full textCampylobacter jejuni is a highly diverse species of bacteria commonly associated with infectious intestinal disease of humans and zoonotic carriage in poultry, cattle, pigs, and other animals. The species contains a large number of distinct clonal complexes that vary from host generalist lineages commonly found in poultry, livestock, and human disease cases to host-adapted specialized lineages primarily associated with livestock or poultry. Here, we present novel data on the ST403 clonal complex of C. jejuni, a lineage that has not been reported in avian hosts. Our data show that the lineage exhibits a distinctive pattern of intralineage recombination that is accompanied by the presence of lineage-specific restriction-modification systems. Furthermore, we show that the ST403 complex has undergone gene decay at a number of loci. Our data provide a putative link between the lack of association with avian hosts of C. jejuni ST403 and both gene gain and gene loss through nonsense mutations in coding sequences of genes, resulting in pseudogene formation

Alle wichtigen Phasen der republikanischen Geschichte entfalten sich: die Ständekämpfe, Aufstieg Roms zur Weltherrschaft - und die zugehörigen ungeheuren kriegerischen Auseinandersetzungen -, Ursachen und Beginn der inneren Krise seit den Gracchen, die Restauration unter Sulla und schließlich: die Auflösung der Republik und die Begründung der Monarchie.

Using Traditional Text Analysis and Large Language Models in Service Failure and Recovery
No full textService failure and recovery (SFR) typically involves one or more people (or machines) talking or writing to each other in a goal-directed conversation. While SFR represents a prime context to understand how language reflects and shapes the service experience, this subfield has only begun to apply text analysis methods and language theories to this context. This tutorial offers a methodological guide for traditional text analysis methods and large language models and suggests some future research paths in SFR. We also provide user-friendly workflow repositories, in Python and KNIME Analytics, that researchers with (and without) coding experience can use. In doing so, we hope to encourage the next wave of text analysis in SFR researc
Focus asymmetries in Bura
No full textThis article presents the central aspects of the focus system of Bura (Chadic), which exhibits a number of asymmetries: Grammatical focus marking is obligatory only with focused subjects, where focus is marked by the particle án following the subject. Focused subjects remain in situ and the complement of án is a regular VP. With nonsubject foci, án appears in a cleft-structure between the fronted focus constituent and a relative clause. We present a semantically unified analysis of focus marking in Bura that treats the particle as a focusmarking copula in T that takes a property-denoting expression (the background) and an individual-denoting expression (the focus) as arguments. The article also investigates the realization of predicate and polarity focus, which are almost never marked. The upshot of the discussion is that Bura shares many characteristic traits of focus marking with other Chadic languages, but it crucially differs in exhibiting a structural difference in the marking of focus on subjects and non-subject constituents

Design, validation and application of an ocular Shack-Hartmann aberrometer
No full textThe design and testing of an ocular Shack-Hartmann aberrometer is presented. The aberrometer objectively measures optical aberrations in the human eye in vivo. The sensor was successfully tested for measurements of refractive error (sphere and cylinder) and spherical aberration. Vignetting limits the measurement range of the wavefront to a range of -10 D to +15 D. Large refractive errors and decentration of the measurement induce aberrations in the test wavefront. Analytical tools to correct for these systematic errors were developed. A clinical study was conducted assessing visual performance in 158 eyes of 89 subjects before and after LARK refractive surgery. The main results of the study were that refractive surgery corrects refractive errors very accurately. A slight regression in refraction during the 12 months after surgery was noted. Measurements of ocular aberrations using the Shack-Hartmann aberrometer revealed that refractive surgery introduced large amounts of higher order aberrations, mainly spherical aberration and coma. The amount of aberrations changed significantly during the 12 months wound healing period. The dark adapted pupil diameter of the eye increased significantly during the first 6 months after surgery. The changes in ocular aberrations and pupil diameter were correlated to changes in contrast sensitivity in the human eye. The analysis of corneal topography showed that while the anterior corneal curvature changed due to surgery, we also saw a change in the posterior corneal curvature as a biomechanical response to surgery. A Customized Eye Model was designed and tested based on the clinical measurements. The model used conic surfaces and modeled defocus and spherical aberration. This computer eye model was then used in optical lens design software to calculate an optimal Customized Ablation Pattern for individual eyes

The systematic position of Plagiochila surinamensis inferred from nrDNA its sequences, morphology and phytochemistry
No full textNeotropical Plagiochila surinamensis differs from P (sect. Rutilantes) gymnocalycina in having fragile leaf teeth. Phylogenetic analyses of nrITS sequences of several representatives of P. sects. Rutilantes and Arrectae lead to a well-resolved topology in which P surinamensis is placed sister to P gymnocalycina with good bootstrap support. The phytochemical profile of a deuterochloroform extract of P surinamensis consists essentially of 4-hydroxy-3'-methoxybibenzyl and beta-phellandrene, a combination observed previously in P gymnocalycina only. Based on this topology and the morphological and phytochemical similarities, P surinamensis is reduced to a variety of P gymnocalycina. Plagiochila wolfii is placed in the synonymy of P gymnocalycina var. surinamensis

Testing hypotheses on species delimitations and disjunctions in the liverwort Bryopteris (Jungermanniopsida : Lejeuneaceae)
No full textNucleoticle sequence variation in the ITS1-5.8S-ITS2 region of nuclear ribosomal DNA and in the trnL-trnF region of chloroplast DNA from 49 specimens of Bryopteris (Lejeuneaceae) and three outgroup species was analyzed using maximum parsimony and maximum likelihood. The nrITS region exhibits high levels of nucleotide variation, whereas the trnL-trnF region is fairly similar among samples of the same species. Three major clades were found corresponding to the Neotropical species Bryopteris diffusa and Bryopteris filicina, as well as Bryopteris gaudichaudii from the Malagasy region. Morphological characters utilized in earlier studies to distinguish five microspecies within B. filicina are diffusely distributed in the molecular topologies and do not trace monophyletic lineages. The nrlTS signal suggests a separation into two biogeographically defined B. filicina clades-one mainly Andean clade and one mainly northern Neotropical clade-but these clades lack statisticat support. The two clades can possibly be explained by the hypothesis that the nrITS signal reflects a former disjunct range of B. filicina with a few subsequent dispersal events. Bryopteris gaudichaudii is resolved as sister of B. filicina; these species are in turn sister to B. diffusa. Clocklike evolution of nr1TS1 and 2 and nrITS sequence divergence estimates from the literature allow for a rough estimation of the divergence time of Bryopteris, indicating a separation of B. gaudichaudii from B. filicina in the Miocene, separation of B. diffusa in the Early Tertiary, and an emergence of Bryopteris in the Cretaceous. The African-American range of Bryopteris is not the result of vicariance but of dispersal
