In part, this can be attributed to the difficulty of investigating secondary growth in situ in a non-invasive manner, in part to the relatively big scale of the process.
Secondly, it was to evaluate the effectiveness of the system according to two different difficulty levels of a cognitive secondary task.
A few experiments have attempted to vary the difficulty of the secondary task and measure the effect on motor control or adaptation [17], [26], however, these experiments utilized memory data-limited tasks [10], [27], [28].
However, another study using a dual-task paradigm (Adam et al., 2008) found evidence for a foveal bias in perceived location that was modulated by the difficulty of the secondary task at fixation.
A new report into what children are reading at school shows a "marked downturn in difficulty of books at secondary transfer", it was revealed today.
The difficulty of inferring the secondary or tertiary structure of transmembrane proteins using experimental techniques has led to a surge of interest in applying techniques from machine learning and bioinformatics to infer secondary structure from primary structure in these proteins.
Thus, there is a relation between potential difficulties of the secondary schooling system and professional schools for medical training, and the former may constrain the latter from finding enough potential trainees.
The presence of such pervasive difficulties with language skills suggests that the difficulties are not simply a secondary consequence of motor or articulatory limitations.
We also discuss practical, logistical, and methodologic difficulties of linking multiple secondary data sources with different levels of person, place, and time descriptors.
