"Table 1" of "Study of the CP asymmetry of B0 ---> J / psi K0(S) decays in ALEPH"
2003
Standard Model predicts the time-dependent rate asymmetry as follows: A(t) = (B0(t)-BBAR0(t))/(B0(t)+BBAR0(t)) = SIN(2*BETA)*SIN(Delta(M)*t), where Delta(M) is the mass difference between the two B0 mass eigenstates.

The DSYS error is due to the error in the branching ratio.
Spanish geographers works and the evolution of the geographical
2005
En este artículo se analiza la evolución y características de los trabajos de los geógrafos españoles difundidos desde 1975 hasta hoy en tres medios de comunicación interdisciplinares especializados en temas regionales, relacionando estos cambios con la evolución de la investigación geográfica en España. Los resultados muestran que desde principios de los años 80 ha ido aumentando el interés por los temas aplicados (políticas de desarrollo regional, planeamiento y políticas urbanas, planificación y ordenación del territorio) e incrementándose el uso de las técnicas cuantitativas. sin embargo, desde mediados de los años 90 hasta hoy la participación de los geógrafos, que fue muy importante e…
Bezpieczeństwo granic Unii Europejskiej w kontekście kryzysu migracyjnego 2015/2016
2016
The European Union is a space within which the freedom of movement of citizens, expressed through freedom to travel. work, study or live in a chosen EU country, is realized. The implementation of this freedom was a result of the abolition of Controls at internal borders of the Union. However. for a Member of the EU, the price of this freedom is the necessity to ensure national security, which makes the protection of external borders a special task. The European Union, through the Schengen Agreement, created institutions for the protection of external borders in terms of ensuring the national security of Member States, The current migration crisis is a serious verification of the effectivene…

SIG/SIG(C=ALL-X-INTERVAL) is fraction of events in bin. Third and fourth systematic errors are due to variation of D** and B** contributions respectively (model dependent, see text).

"Table 1" of "Measurement of the forward-backward asymmetry in $\Lambda_b^0$ and $\overline \Lambda_b^0$ baryon production in $p \overline p$ collisi…
2016
Efficiencies $\epsilon$, averaged values of background-subtracted transverse momenta $\left< p_T\right>$, backward and forward fitted yields for the signal $N(B)$ and $N(F)$, forward-backward asymmetries $A$, and cross-section ratios $R$ in four intervals of rapidity. Uncertainties on $\left< p_T\right>$, $N(B)$ and $N(F)$ are statistical only. Uncertainties on $\epsilon$ arise from the statistical precision of the simulated event samples.
