Thin Filaments in an Average Magnetosphere: Pure Interchange vs. Ballooning Oscillations
<p>This paper describes magnetospheric waves of very long wavelength in thin magnetic filaments. We consider an average magnetospheric configuration with zero ionospheric conductance and calculate waves using two different formulations: classic interchange theory and ideal MHD. Classic interchange theory, which is developed in detail in this paper, is basically analytic and is relatively straightforward to determine computationally, but it can’t offer very high accuracy.</p> <p>The two formalisms agree well for the plasma sheet and also for the inner magnetosphere. The eigenfrequencies range over about a factor of seven, but the formulations generally agree with a root-mean-square difference between the logarithms of interchange and MHD frequencies to be $\sim 0.054$. The pressure perturbations in the classic interchange theory are assumed constant along each field line, but the MHD computed pressure perturbations along the field line vary in a range $\sim 30 \%$ in the plasma sheet but are larger in the inner magnetosphere. The parallel and perpendicular displacements, which are very different in the plasma sheet and inner magnetosphere, show good qualitative agreement between the two approaches. In the plasma sheet, the perpendicular displacements are strongly concentrated in the equatorial plane, whereas the parallel displacements are spread through most of the plasma sheet away from the equatorial plane; and can be regarded as buoyancy waves. In the inner magnetosphere, the displacements are more sinusoidal and are more like conventional slow modes. The different forms of the waves are best characterized by the flux tube entropy $PV^\gamma$.</p>

Data from: Neogene sloth assemblages (Mammalia, Pilosa) of the Cocinetas Basin (La Guajira, Colombia): implications for the Great American Biotic Interchange
We describe sloth assemblages from the Cocinetas Basin (La Guajira peninsula, Colombia), found in the Neogene Castilletes and Ware formations, located in northernmost South America, documenting otherwise poorly known biotas. The tentative referral of a specimen to a small megatherioid sloth, Hyperleptus?, from the early–middle Miocene Castilletes Formation, suggests affinities of this fauna with the distant Santa Cruz Formation and documents a large latitudinal distribution for this taxon. The late Pliocene Ware Formation is much more diverse, with five distinct taxa representing every family of 'ground sloths'. This diversity is also remarkable at the ecological level, with sloths spanning over two orders of magnitude of body mass and probably having different feeding strategies. Being only a few hundred kilometres away from the Isthmus of Panama, and a few hundred thousand years older than the classically recognized first main pulse of the Great American Biotic interchange (GABI 1), the Ware Formation furthermore documents an important fauna for the understanding of this major event in Neogene palaeobiogeography. The sloths for which unambiguous affinities were recovered are not closely related to the early immigrants found in North America before GABI 1.
Data from: dispersal sweepstakes: biotic interchange propelled air-breathing fishes across the globe
<p>Synbranchiformes is a phenotypically diverse and species rich clade of freshwater acanthomorph fishes, which include eel- and perch-like, air-breathing and non-air-breathing fishes. The ability to breathe out of water has presumably aided lineages of Synbranchiformes in dispersing across all southern continents except Antarctica. The lack of a well-resolved, time-calibrated phylogeny of Synbranchiformes limits our understanding of the timing and geographic patterns of diversification of these anatomically and ecologically diverse fishes. As a consequence, contemporary interpretations of synbranchiform biogeography invoke scenarios as disparate as Gondwana vicariance and pan-global rafting to explain their modern-day geographic distribution. In this study, we use high-throughput sequencing of ultra-conserved elements (UCEs) to infer a phylogeny for all major synbranchiform lineages. We combine this dataset with existing Sanger sequenced genes and fossil calibrations to infer a comprehensive time-calibrated phylogeny of Synbranchiformes. Then, we use Bayesian methods of biogeographical reconstruction to document the history of dispersal of synbranchiforms, finding support for Southeast Asia as the likely ancestral area of all major lineages. Our results reject the hypothesis of Gondwanan vicariance explaining synbranchiform biogeography, and instead the historical biogeographic analyses support a hypothesis of independent continental invasions by snakeheads, anabantids, and spiny eels. However, there is no signal of elevated lineage diversification rates after these invasions. Instead, higher rates of lineage diversification in spiny eels pre-dates their arrival to Africa, while the high levels of lineage diversification observed in <em>Betta</em> were initiated prior to the flooding of insular Sundaland in SE Asia.</p>
Culture Graph Interchange Format Specification
<p>For the federated acquisition of data for the <a href="https://nfdi4culture.de/resources/knowledge-graph.html">Culture Knowledge Graph</a> <strong>we propose an easy to use, lightweight interchange format</strong> based on <a href="https://schema.org/">schema.org</a> for the harvesting of resources from data collections with key attributes (IRIs, names, dates and terms from controlled vocabularies). The <strong><em>Culture Graph Interchange Format</em></strong> <strong>(CGIF)</strong> has the added benefit of automatically making the data eligible for <a href="https://datasetsearch.research.google.com/">Google Dataset Search</a> and to significantly improve the findability of websites and datasets through search engine optimization.</p> <p>This is the data publication (source files, figures, post-use materials) of the CGIF specification.

Innovative intersection and interchange designs and their use across the Southeast [Dataset]
<p><span>Innovative intersection designs have become more widely implemented in the United States, due to their well-studied operational and safety benefits while minimizing cost and right-of-way acquisition. Although many states have aggressively pursued implementation of these intersections, there is still a demonstrated need to provide additional insight on the design, operation and safety of these innovative intersections. This project helps address this need by both evaluating use of existing innovative intersections and supporting further implementation of these innovative intersection designs through advancing safety analysis, providing guidance on assessing the comfort and safety of pedestrians and bicyclists at innovative intersections, expanding available performance measures, and improving operational analysis through the application of Naturalistic Driving Study (NDS) data.</span></p> <p><span>The data set consists of the Vissim files used to create the simulation model for the emissions analysis.</span></p>
