Additional data for "Settling velocities of tire and road wear particles: Analyzing finely graded density fractions of samples from a road simulator and a highway tunnel"
No full text<p>This repository provides additional files for the publication "Settling velocities of tire and road wear particles: Analyzing finely graded density fractions of samples from a road simulator and a highway tunnel" by Stefan Dittmar, Steffen Weyrauch, Thorsten Reemtsma, Paul Eisentraut, Korinna Altmann, Aki Sebastian Ruhl and Martin Jekel (DOI: <em>tba</em>).</p>
<p>It contains:<br>- single particle raw data from settling experiments (<strong>1_settling_data.zip</strong>)<br>- cumulative distributions of settling velocity and particle size for each investigated density fraction of both samples (<strong>2_measured_distributions.zip</strong>)<br>- composed cumulative distributions of settling velocity and particle size for incorporated tire material/TRWP from both samples (<strong>3_composed_distributions.zip</strong>)<br>- Python script to compute composed distributions (similar to 3) corrected for water properties differing from the experimental conditions (T=15 °C, salinity=0 g/kg)<br>(<strong>4_correct_temperature_salinity.zip</strong>)</p>
<p>Please consider the included readme files (<strong>0_README</strong>{...}<strong>.txt</strong>) and revisit main publication and supplement information for further context on this data set, especially when you want to implement the data (e.g. from <strong>3_composed_distributions</strong>) or generate corrected composed distributions via the Python script <strong>4_correct_temperature_salinity.py</strong> yourself to be used in future studies.</p>
<p>Please contact Stefan Dittmar ([email protected]), if you have questions in that regard.</p>

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Pelevin’s Trinity in the novel “t”: author – protagonist – reader
No full textThe article attempts to interpret Pelevin's artistic strategy in the novel "T" by exploring its subject organization and addressing the key problems of the author, the protagonist, and the reader as they are seen by the researcher. The article analyzes the peculiarities of constructing the narrative reality in the novel "T", and goes on to discuss Pelevin's philosophic models of the development of the humankind, and the emergence of his new anthropology
What do New-Keynesian Phillips Curves imply for price-level targeting?
No full textThis paper extends the analysis of price-level targeting to a model including the New-Keynesian Phillips Curve. We examine the inflation-output variability tradeoffs implied by optimal inflation and price-level rules. In previous work with the Neoclassical Phillips Curve, we found that the choice between inflation targeting and price-level targeting depended on the amount of persistence in the output gap. That is, if the output gap was not too persistent, or if lagged output did not enter the aggregate supply function, then inflation targets were preferred to price-level targets. When we start with a New-Keynesian Phillips Curve, the amount of persistence in the output gap still affects the relative placement of the inflation-output variability tradeoff. But, contrary to the Neoclassical case, even where the persistence of the output gap in the aggregate supply function is small or nonexistent, the price-level- targeting regime still results in a more favorable tradeoff between output and inflation variability than does an inflation-targeting regime.Phillips curve ; Monetary policy ; Inflation (Finance)
