If detection difficulty modulates dwell times on top of similarity, then we would expect dwell times to be longest on thin distractors in the thin target condition, and shortest on thick distractors in the thick target condition, with intermediate dwell times for medium distractors in the medium target condition.
This search requires a high intensity muon beam stopping in a thin target with the maximum rate compatible with the background from combinatorial events.
The interaction was due the fact that, in the medium and thick target conditions, misses occurred significantly more frequently than false alarms (all ps<.001), whereas these did not differ in the thin target condition (p = .86).86
In summary, the proton cut-off energy versus target thickness presents a maximum for very thin targets, where LDCSA is the dominant acceleration mechanism.
Furthermore, a 24-gauge catheter can appear to be in the same plane as a thin target vein on in-plane views, even in unsuccessful catheterisation.
Separate 2×2 ANOVAs comparing the number of fixations on two distractor types (thick vs. medium, medium vs. thin, thick vs. thin) on present versus absent trials confirmed that, in search for a thin target, thin distractors were significantly more frequently selected than medium distractors (F 1,11) = 435.5; p<.001) and thick distractors (F 1,11) = 429.5; p<.001).
Separate analyses revealed that, in search for a thin target, dwell times on thin distractors were longest, significantly longer than dwell times on medium distractors (F 1,11) = 63.7; p<.001) and thick distractors (F 1,11) = 85.3; p<.001), whereas dwell times on medium and thick distractors did not differ (F 1,11) = 2.7; p<.13).
High energy neutrons produced in the forward direction from thin target beam losses are a major component of the dose rate outside the shield walls of the tunnel.
The berkelium's next stop was Russia's Research Institute of Atomic Reactors in Dimitrovgrad, where scientists crafted the berkelium into a thin target and then on to JINR, where physicists pummeled the target with calcium-48 ions day and night for 5 months.
Finally, we can vary z o = z f + z, and determine how the thin target signal degrades with defocusing, z, in order to evaluate sectioning ability.
