Thus, measuring the time allocated for decision making by free-flying honeybees confronted with tasks of different difficulty may constitute an interesting research perspective for the future [35] [36].
The diverse set (see Supplementary Material) included targets of different difficulty, different sizes and different secondary structure types.
These findings are not unexpected since the various items within the scales are of different difficulty level.
Finally, apart from the K-means clustering algorithm used for clustering quizzes of different difficulty levels, we will consider using more advanced clustering [ 17, 35] and classification algorithms [ 10, 11] to perform better online learning of the quiz difficulty levels based on real-time user feedbacks.
In addition, the relative influence of the error variance attributable to physicians of different competency levels interacting with patient cases of different difficulty (the pc effect) was reduced by a factor 3 using the checklist instead of global ratings (Table 2).
In an event-related design, participants performed Tower of London task trials of four different difficulty levels, alternating with corresponding baseline trials, all implemented in E-prime 1.1 sPsychology Software Toolsools).
No. 1 Victoria Azarenka and No. 4 Serena Williams will meet in the 2012 United States Open final, after winning semifinals Friday of very different difficulty levels.
Nevertheless, differences in the structure and chemical composition of different barks, difficulties of separating bark from wood when in the form of particles, and differences in the properties of inner and outer bark have impeded fuller utilization.
Even though there is substantial overlap in the symptom profiles of different learning difficulties (Gilger and Kaplan, 2001), it has also been suggested that learning difficulties often exhibit more specialized impairments (Scanlon, 2013).
