title: Biermann-battery driven magnetized collisionless shock precursors in laser produced plasmas

description: This letter reports the first complete observation of magnetized collisionless shock precursors formed through the compression of Biermann-battery magnetic fields in laser produced plasmas. At OMEGA, lasers produce a supersonic CH plasma flow which is magnetized with Biermann-battery magnetic fields. The plasma flow collides with an unmagnetized hydrogen gas jet plasma to create a magnetized shock precursor. The situation where the flowing plasma carries the magnetic field is similar to the Venusian bow shock. Imaging 2ω Thomson scattering confirms that the interaction is collisionless and shows density and temperature jumps. Proton radiographs have regions of strong deflections and FLASH magnetohydrodynamic (MHD) simulations show the presence of Biermann fields in the Thomson scattering region. Electrons are accelerated to energies of up to 100 keV in a power-law spectrum. OSIRIS particle-in-cell (PIC) simulations, initialized with measured parameters, show the formation of a magnetized shock precursor and corroborate the experimental observables.

title: Replication Data for: Exporting the Tools of Dictatorship: The Politics of China's Technology Transfers

description: The Chinese government is revolutionizing digital surveillance at home and exporting these technologies abroad. Do these technology transfers help recipient governments expand digital surveillance, impose internet shutdowns, filter the internet, and target repression for online content? We focus on Huawei, the world's largest telecommunications provider, which is partly state-owned and increasingly regarded as an instrument of its foreign policy. Using a global sample and an identification strategy based on generalized synthetic controls, we show that the effect of Huawei transfers depends on preexisting political institutions in recipient countries. In the world's autocracies, Huawei technology facilitates digital repression. We find no effect in the world’s democracies, which are more likely to have laws that regulate digital privacy, institutions that punish government violations, and vibrant civil societies that step in when institutions come under strain. Most broadly, this article advances a large literature about the geopolitical implications of China's rise.

title: Identifying Wave Drag for the Generic Drag Polar Equation – Unveiling Polars of 16 Passenger Aircraft
title: Links to all related documents:

description: Purpose – This work systematically derives the best form of a generic drag polar equation together with the optimum numerical values of its parameters to unveil the drag coefficient of 16 passenger aircraft as a function of lift coefficient and Mach number. The parameters are selected such that they can be estimated also for other aircraft mainly from their geometry. ---
Methodology – Drag polars in graphical form from Obert (2009) are the starting point. Numerical values of the drag coefficient are obtained with the WebPlotDigitizer. In the generic equation, zero lift drag is assumed constant, the term representing induced drag is taken from Niţă (2012). For the wave drag term, seven functions of Mach number are investigated. The difference between Mach number and critical Mach number to the power of 4 is the classic approach based on Lock (1951). Two more general power functions, tan, tanh, sinh, and an exponential function are looked at. Parameters are optimized by minimizing the Root Mean Squared Percentage Error (RMSPE). Optimization is done with the Solver in Excel using the Generalized Reduced Gradient (GRG2) code supplied by Frontline Systems. ---
Findings – Based on all 16 investigated aircraft, a generic drag polar using the hyperbolic tangent (tanh) to express wave drag is best with mean RMSPE of only 0.68%. The second best is the most general power function with mean RMSPE of 0.75%. Its special case, the often quoted but unflexible function from Lock comes out last here with a mean RMSPE of 0.95%. Nevertheless, all seven functions can be used to represent wave drag. The zero lift drag coefficient is identified between 0.013 (B777) and 0.020 (A320). The Mach dependence of the drag coefficient comes not only from wave drag, but also from induced drag and its Mach dependence beyond 0.3 Mach. Calculated parameters are plausible and come close to reference values from literature. ---
Research Limitations – Aerodynamic data is generally confidential. Therefore, public drag data is limited. The extension of the method to other aircraft yields a drag estimate. ---
Practical Implications – The generic equation can be used in preliminary aircraft design as well as in calculations in aircraft performance and flight operations. ---
Originality – This project formulates a generic drag polar equation with a choice of new wave drag terms some based on a historic precursor. The new approach with a hyperbolic tangent function is recommended.

title: Replication Data for: Massive dolomitization of interior and slope to basin-margin facies of the Triassic Yangtze Platform through superposed earth-surface and burial mechanisms; Nanpanjiang Basin, south China

description: This database presents fluid inclusion microthermometry, stable isotope geochemistry, rare earth element data, and U-Pb age dates of dolomite samples collected from the Yangtze Platform in southern Guizhou Province from 2015 to 2024. Laboratory work was completed at Trinity University and the University of Green Bay. U-Pb geochronology, Sr isotope analysis, REE data were collected at Stony Brook University and the University of Arizona. Triassic strata of the Yangtze Platform at Guanling contain a dolomitized interior, undolomitized margin, and partially dolomitized slope to basin margin. Dolomitized microbial laminate caps of peritidal cycles and massive dolomite with associated evaporite nodules and solution collapse breccias are consistent with penecontemporaneous tidal flat and evaporative dolomitization in the platform interior. Preferential dolomitization of the slope and basin margin (up to 7 km basinward of the margin), dolomitization along fractures, and selective dolomitization of matrix in slope breccia that diminishes toward the margin is interpreted to have resulted from incursion of basin-derived fluids during burial. Integrated analysis of fluid-inclusion microthermometry, oxygen, carbon and strontium isotopes, trace element geochemistry, U-Pb age dates of carbonate phases and burial history support recrystallization of interior dolomite and slope to basin-margin dolomitization by brines at high temperatures during burial. The Yangtze Platform at Guanling provides an excellent example of widespread stratiform dolomitization resulting from the superposition of multiple mechanisms including penecontemporaneous dolomitization by evaporative seawater brines, high-temperature dolomitization of the slope and basin margin by basinal brines and high temperature recrystallization of dolomite by brines during burial. Similar mechanisms likely contributed to the widespread dolomitization of platforms across the Nanpanjiang and Sichuan basins. This study suggests that many widespread stratiform dolomites in the rock record may result from superposed Earth surface and high-temperature burial dolomitization processes. The study also provides a useful analogue for other platforms in which the margin remains undolomitized while the interior and basin margin are dolomitized.

The Community Rating System (CRS) is a voluntary incentive program that recognizes and encourages community floodplain management practices that exceed the minimum requirements of the National Flood Insurance Program (NFIP). Over 1,500 communities participate nationwide.
&lt;br /&gt;&lt;br /&gt;
This dataset includes:
1. Community Rating System eligible communities, effective October 1, 2024
2. CRS Communities Credit File, which provides detailed data about the credit points each CRS community receives
&lt;br /&gt;&lt;br /&gt;
In CRS communities, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from the community’s efforts that address the three goals of the program:
(1) Reduce and avoid flood damage to insurable property
(2) Strengthen and support the insurance aspects of the National Flood Insurance Program
(3) Foster comprehensive floodplain management
&lt;br /&gt;&lt;br /&gt;
Flood insurance premium discounts in CRS communities range from 5% to 45% and are discounted in increments of 5%. A Class 10 community is not participating in the CRS and receives no discount. A Class 9 community receives a 5% discount for all policies, a Class 8 community receives a 10% discount, all the way to a Class 1 community, which receives a 45% premium discount.
&lt;br /&gt;&lt;br /&gt;
Classifications are based on the community’s CRS credit points obtained in 19 creditable activities. The CRS activities are organized in four categories:
1. Public Information
2. Mapping and Regulations
3. Flood Damage Reduction
4. Warning and Response
&lt;br /&gt;

title: Isolation of Weissella cibaria from Pacific White Shrimp (Litopenaeus vannamei) Gastrointestinal Tract and Evaluation of Its Pathogenic Bacterial Inhibition

description: Abstract
Objective: The present study reported the isolation of lactic acid bacteria from the shrimp gastrointestinal tract and evaluation of its antagonistic activity against pathogenic bacteria.

Methods/ statistical analysis: Lactic bacteria from the gastrointestinal tract of alive healthy shrimp were screened on sterilized MRS medium. Vibrio sp. inhibition by isolates was conducted by the agar-well diffusion assay. The isolates were identified by 16S rRNA sequencing. Antibacterial activity was investigated against 25 Vibrio sp. isolates, Staphylococcus aureus ATCC 25023, and Escherichia coli ATCC 85922. Hemolytic activity, salt, and antibiotic resistance were also evaluated.

Findings: Total of 22 isolates exhibited Vibrio parahaemolyticus inhibition with antagonistic activities ranged from 220 AU/ml to 460 AU/ml. Sequence analysis of 16S rRNA indicated the 5 isolates belong to Weissella cibaria species, namely HN02, HN03, HN04, and HN06 AND HN07. Among these, W. cibaria HN05 had highest antagonistic activity and exhibited the broad inhibition spectrum against Vibrio sp. as well as E. coli ATCC 85922 but not S. aureus ATCC 25023. β-hemolytic and salt resistance assays showed that W. cibaria HN05 had no β-hemolytic activity and grew well in medium containing 5% of salt. Antibiotic resistance analysis indicated W. cibaria HN05 was suppressed by ampicillin, chloramphenicol, oxytetracycline hydrochloride, and chlortetracycline hydrochloride.

Application/improvements: This is the first study on isolation and evaluation pathogenic bacteria including Vibrio sp. inhibition by W. cibaria, which is isolated from shrimp gastrointestinal tract.

title: Replication Data for: Race, Diversity, and the Development of Political Attitudes on College Campuses

description: Faced with demographic change, many colleges are offering courses on race and ethnicity. How does taking race-centered courses affect public opinion? We theorize that while White, Latino, and Asian American students develop inclusive political attitudes through race-centered coursework, Black Americans may already enter college with a deeper understanding about racial issues. We test these expectations using two longitudinal multi-racial datasets. First, using a national panel survey of college students, we find that ethnic studies coursework is associated with increased recognition of racial discrimination among Whites, Latinos, and even Black Americans. Second, using an original panel survey from a public university, we find reduced racial resentment and increased affirmative action support - albeit varied - among Whites, Latinos, and Asian Americans after completing race-centered political science classes but not in placebo politics classes that were not focused on race. Our findings have implications for conversations about race-centered coursework in higher education.

title: Replication Data for: The case for multiple UESDs and an application to migrant deaths in the Mediterranean Sea

description: Many recent applications of the "Unexpected Event during Survey Design" (UESD) analyze single cases of frequently occurring events. In this research note, I question the generalizability of research findings obtained this way and demonstrate the empirical benefits of the “Multiple Unexpected Events during Survey Design” (MUESD). I conduct fifteen large-scale replications (total N = 101,940) of a new UESD analyzing the effects of Mediterranean shipwrecks on immigration attitudes. Previous research suggests that such events drastically reduce anti-immigration attitudes among the European public, presumably through an empathy-based mechanism. However, after fifteen of the most lethal shipwrecks since 2013, anti-immigration attitudes were reduced in only one case of exceptionally high salience, and to a much lesser degree than originally found.

title: Replication Data for: Unorthodox Lawmaking and the Value of Committee Assignments

description: Do unorthodox lawmaking processes reduce the influence provided to lawmakers by their committee assignments? In recent decades, Congress has increasingly used "unorthodox" processes to consider and pass legislation. Included among these unorthodox approaches is a more frequent bypassing of formal committee-led processes. Some scholars and observers expect that these violations of the "regular order" may reduce the influence committee members have on policy outcomes. However, this intuition has not been tested in any systematic way. Drawing on data every federal formula grant program reauthorized more than one time since 1980, we compare amounts going to states across programs that were and were not subject to formal committee mark-ups and conferences during reauthorization efforts. We do not find any evidence that the value of a committee seat is affected by whether or not committee-led stages of the legislative process are bypassed.

title: Replication Data for: Equivalency Framing of Problems and Policy Solutions

description: While there is a large political science literature on framing effects, almost none of it has focused on equivalency framing of actual problems and potential solutions. We investigate whether the public expresses more concern about societal problems when logically equivalent information concerning their prevalence is framed in negative rather than in positive terms, and whether support for ameliorative policies changes when policies are framed as reducing the incidence of bad outcomes as opposed to increasing the incidence of good ones. From experiments covering a diverse set of issues, we find that equivalency frames have a consistent effect on the public’s evaluation of social problems: negative frames provoke substantially more negative emotional reactions to problems and lead to judgments that the problems are more serious and deserving of government attention. At the same time, we find no differences in support for gain-framed versus loss-framed policies designed to ameliorate these problems.
