"Table 13" of "Update of electroweak parameters from Z decays"
1993
Data for 1991 running period.
"Table 25" of "Measurements of the line shape of the Z0 and determination of electroweak parameters from its hadronic and leptonic decays"
1994
LEPTON+ LEPTON- forward-backward asymmetries from the 1991 data set. Data are corrected for t-channel subtraction, and to full solid angle but not for momenta and accollinearity cuts. Additional systematic uncertainty, excluding luminosity, is 0.0025.
"Table 2" of "Measurements of the line shape of the Z0 and determination of electroweak parameters from its hadronic and leptonic decays"
1994
Hadronic cross sections from the 1991 data set. Additional systematic uncertainties come from efficiencies and background of 0.2 pct in addition to the luminosity uncertainty 0.6 pct.
"Table 21" of "Measurements of the line shape of the Z0 and determination of electroweak parameters from its hadronic and leptonic decays"
1994
TAU+ TAU- forward-backward asymmetries from the 1991 data set, corrected to full solid angle. Additional systematic error is 0.003 at the peak.
"Table 8" of "Measurements of the line shape of the Z0 and determination of electroweak parameters from its hadronic and leptonic decays"
1994
E+ E- forward-backward asymmetries from the 1991 data set for both final state fermions in the polar angle range 44 to 136 degrees and accollinearity < 10 degrees (the s + t data). Additional systematic error, excluding luminosity, is 0.002.
"Table 10" of "Measurements of the line shape of the Z0 and determination of electroweak parameters from its hadronic and leptonic decays"
1994
E+ E- forward-backward asymmetries from the 1991 data set after t-channel subtraction with only the E- constraint by polar angle 44 to 136 degrees and accollinearity < 10 degrees. Additional systematic error, excluding luminosity, is 0.003 at the peak.
"Table 2" of "Cross-sections and leptonic forward-backward asymmetries from the Z0 running of LEP."
2000
Hadronic cross section measured with the 1994 data. Additional systematic error of 0.11 PCT (efficiencies and backgrounds) and 0.11 PCT (absolute luminosity).
"Table 1" of "A Comparison of jet production rates on the Z0 resonance to perturbative QCD"
1990
Corrected jet rates.
Seasonal Changes in Urban PM2.5 Hotspots and Sources from Low-Cost Sensors
2022
PM2.5 concentrations in urban areas are highly variable, both spatially and seasonally. To assess these patterns and the underlying sources, we conducted PM2.5 exposure measurements at the adult breath level (1.6 m) along three ~5 km routes in urban districts of Mainz (Germany) using portable low-cost Alphasense OPC-N3 sensors. The survey took place on five consecutive days including four runs each day (38 in total) in September 2020 and March 2021. While the between-sensor accuracy was tested to be good (R² = 0.98), the recorded PM2.5 values underestimated the official measurement station data by up to 25 µg/m3. The collected data showed no consistent PM2.5 hotspots between September and M…
The WHO-5 Well-Being Index – Validation based on item response theory and the analysis of measurement invariance across 35 countries.
2020
Abstract Background The five-item World Health Organization Well-Being Index (WHO-5) is a frequently used brief standard measure in large-scale cross-cultural clinical studies. Despite its frequent use, some psychometric questions remain that concern the choice of an adequate item response theory (IRT) model, the evaluation of reliability at important cutoff points, and most importantly the assessment of measurement invariance across countries. Methods Data from the 6th European Working Condition survey (2015) were used that collected nationally representative samples of employed and self-employed individuals (N = 43,469) via computer-aided personal interviews across 35 European countries. …
