Performance of the ATLAS Level-1 topological trigger in Run 2

During LHC Run 2 (2015–2018) the ATLAS Level-1 topological trigger allowed efficient data-taking by the ATLAS experiment at luminosities up to 2.1$$\times $$ × 10$$^{34}$$ 34 cm$$^{-2}$$ - 2 s$$^{-1}$$ - 1 , which exceeds the design value by a factor of two. The system was installed in 2016 and operated in 2017 and 2018. It uses Field Programmable Gate Array processors to select interesting events by placing kinematic and angular requirements on electromagnetic clusters, jets, $$\tau $$ τ -leptons, muons and the missing transverse energy. It allowed to significantly improve the background event rejection and signal event acceptance, in particular for Higgs and B-physics processes.

Indonesian Civil War: Comparing Discourse In the Campaign of Jakarta’s 2017 Gubernatorial Election

Political discourse today is no longer dependent on the performance of the political elite; however, it has shifted to active participation of their supporters. This phenomenon is widely recorded in social media as the background event. Without exception to Jakarta’s 2017 Gubernatorial Election that received an international spotlight because the roar is so massive in the universe of cyberspace. This qualitative descriptive study examined the pattern of campaign movements as a political discourse conducted by the public in supporters community account as a form of public participation in the politics of free-active democracy. It aimed to map out the pattern of discourse movements arising from the supporter community accounts of one of the candidate through the perspective of the discourse comparison offered by Sawirman (2014). The findings show that there are three supporting accounts of candidates which posited as primary, secondary and tertiary discourse. For the configuration of the discourse, gradable adjectives are used as a linguistic strategy to weaken and to dispel sympathy for opposing factions. It is based on the spirit that speakers are superior to their rivals. In general, the pattern of discourse movements identified is synergistic and mutual in order to demonstrate the superiority of their group by degrading the opposing side.

Effects of Background Event Rate and Critical Signal Amplitude on Vigilance Performance

Ss monitored a display consisting of the repetitive presentation of pairs of movements of a bar of light. A neutral background event, for which no overt response was required, was a double deflection of 24 mm. The critical signal for detection was a longer deflection in the second movement within an event. Detection probability was greater for incremental excursions of 33% relative to 8.3% of the base movement. This effect was enhanced twofold when the event rate in which the signals were embedded was 21 as compared to 6 events/min. The results are considered in terms of the elicited observing rate hypothesis proposed by Jerison (1970).
