Accurate thermal conductivities from optimally short molecular dynamics simulations
No full textThe evaluation of transport coefficients in extended systems, such as thermal conductivity or shear viscosity, is known to require impractically long simulations, thus calling for a paradigm shift that would allow to deploy state-of-the-art quantum simulation methods. We introduce a new method to compute these coefficients from optimally short molecular dynamics simulations, based on the Green-Kubo theory of linear response and the cepstral analysis of time series. Information from the full sample power spectrum of the relevant current for a single and relatively short trajectory is leveraged to evaluate and optimally reduce the noise affecting its zero-frequency value, whose expectation is proportional to the corresponding conductivity. Our method is unbiased and consistent, in that both the resulting bias and statistical error can be made arbitrarily small in the long-time limit. A simple data-analysis protocol is proposed and validated with the calculation of thermal conductivities in the paradigmatic cases of elemental and molecular fluids (liquid Ar and H2O) and of crystalline and glassy solids (MgO and a-SiO2). We find that simulation times of one to a few hundred picoseconds are sufficient in these systems to achieve an accuracy of the order of 10% on the estimated thermal conductivities.THEO
Uma proposta de ensino de literatura a partir da obra do escritor alagoano Ari Denisson
No full textThis research is based on a qualitative investigation, of the action research type, which suggests that literature classes should study the life and work of the author Ari Denisson, a poet and short story writer from Maceió, with the aim of valuing talents from Alagoas and encouraging a taste for reading and literary production. The actions of this project took place in a public school in a first-year high school class in 2024 and focused on the poetic work “baroque.doc” and the narrative work “Contos Periféricos”. A six-hour teaching sequence culminated in the author's visit to the school and a round of questions from the students. The interview was preceded by analyses of the selected texts and a presentation of the author's biography. The expected result is a way of rescuing the culture of Alagoas and Maceió and a greater appreciation of literature in Portuguese language classes. The authors who are references for this research range from Cosson, Boal, Freire, Rojo, to Antunes, among others.A presente pesquisa baseia-se em uma investigação de cunho qualitativo, do tipo pesquisa-ação que sugere para as aulas de literatura o estudo da vida e obra do autor Ari Denisson, poeta e contista maceioense, no intuito de valorizar os talentos alagoanos e incentivar o gosto pela leitura e produção literária.

The Afterlife of Ari Nohem
No full textThis chapter traces the circulation of Ari Nohem in manuscript, from its composition through its first appearance in print. The different stages in the reception of Ari Nohem in manuscript offer an alternative history of Kabbalah in the seventeenth and eighteenth centuries, one that has largely been told through the histories of Sabbatianism and Hasidism. The manuscript transmission of Ari Nohem was typical rather than aberrant for texts written by early modern Jewish intellectuals on a variety of subjects: polemical writings on Christianity, esoteric kabbalistic treatises, and epistolary campaigns against the mystical messiah Sabbatai Zevi and his followers. The evidence of these manuscripts, combined with repeated citation of and allusion to Ari Nohem in letters, diaries, treatises, responsa, and compendia composed between 1639 and 1840, indicate that Jews and Christians continued to read Modena's text in nearly every generation between the death of the author and the printing of his book.</p
Health consultation, Ari-Zonolite (aka Buster's School of Street Rods facility), Glendale, Maricopa County, Arizona
No full textabstract: This report evaluates the potential exposure pathways associated with vermiculite concentrate processing activities at the Ari-Zonolite facility. The site is located in the near downtown area of Glendale, approximately ½ mile from the city hall, downtown shops, and other buildings. The former Ari-Zonolite facility received vermiculite from the Libby, Montana, mine. From 1951 to 1964, the site was leased the site to the Ari-Zonolite Company. Following the removal of the vermiculite concentrate processing equipment in 1964, several businesses have occupied the site. None of these businesses were involved in vermiculite processing activities. The last occupant of the former vermiculite processing building was an automotive restoration business, which vacated the site in 2002.Under cooperative agreement with the Agency for Toxic Substances and Disease Registry, U.S. Department of Health and Human Services.Includes bibliographical references (p. 17-19)
Tallgrass prairie soil fungal communities are resilient to climate change
No full textClimate models for central United States predict increasing temperatures and greater variability in precipitation. Combined, these shifts in environmental conditions impact many ecosystem properties and services. Long‐term climate change experiments, such as the Rainfall Manipulation Plots (RaMPs), can be used to address soil community responses to simultaneous manipulation of temperature and temporal variability in precipitation. The RaMPs experiment is located in a native tallgrass prairie at the Konza Prairie Biological Station and has been operational since 1998 providing the potential to address responses to long‐term environmental manipulations. To test whether community composition, richness, or diversity respond to environmental change, more than 40,000 fungal amplicons were analyzed from soil samples collected in 2006. The data suggest that soil fungal communities are compositionally resilient to predicted environmental change. This is the case both for the community composition overall as inferred from ordination analyses as well as analyses of variance for each of the most common Operational Taxonomic Units (OTUs). However, while this study suggests compositional resilience, further studies are required to address functional attributes of these communities and their responses to environmental manipulations
Septate endophyte colonization and host responses of grasses and forbs native to a tallgrass prairie
No full textNative tallgrass prairies support distinct dark septate endophyte (DSE) communities exemplified by periconia macrospinosa and Microdochium sp. that were recently identified as common root symbionts in this
system. Since these DSE fungi were repeatedly isolated from grasses and forbs, we aimed to test their abilities to
colonize different hosts. One Microdochium and three Periconia strains were screened for colonization and growth responses using five native grasses and six forbs
in an in vitro system. Previously published data for an additional grass (Andropogon gerardii) were included and reanalyzed. Presence of indicative inter- and intracellular structures (melanized hyphae, microsclerotia, and chlamydospores)
demonstrated that all plant species were colonized by the DSE isolates albeit to varying degrees. Microscopic observations suggested that, compared to forbs, grasses were colonized to a greater degree in vitro.
Host biomass responses varied among the host species. In broad comparisons, more grass species than forbs tended to respond positively to colonization, whereas more forb species tended to be non-responsive. Based on the suspected differences
in the levels of colonization, we predicted that tallgrass prairie grasses would support greater DSE colonization than forbs in the field. A survey of field-collected roots from 15
native species supported this hypothesis. Our study supports the “broad host range” of DSE fungi, although the differences
in the rates of colonization in the laboratory and in the field suggest a greater compatibility between grasses and DSE
fungi. Furthermore, host responses to DSE range from mutualism to parasitism, suggesting a genotype-level interplay
between the fungi and their hosts that determines the outcome of this symbiosis
Three essays on stock recommendations:
No full textThis dissertation studies stock recommendations made by columnists and financial analysts. The first essay examines the value and profitability of columnist recommendations published in the Business Week, Forbes and Fortune magazines. Empirical results show that columnist recommendations are not profitable in the short- or long-run controlling for market risk, book-to-market, size and momentum effects. The second essay examines the relation between the value of analysts’ recommendations and corporate research and development (R&D) investments. Univariate, calendar-time portfolio and cross-sectional analyses controlling for risk, business complexity, earnings value-relevance, analyst coverage, institutional ownership and bid-ask spread indicate the value of analysts’ recommendations to be significantly more valuable for firms that are more intensely engaged in R&D investments. The final essay, using stock recommendations, examines Regulation FD’s impact on corporate practice of earnings-related selective disclosure to financial analysts. The comparative analysis of the association between analysts’ revisions and subsequent earnings surprises, in the pre- and post- Regulation FD periods reveals a significant reduction in analysts’ earnings-related private information in the post-Regulation FD period.Ph.D.Includes bibliographical references (p. 130-137)by Ari Yezege
