As subjective aspects, we refer to the questions that are complex to define without human interaction, especially implicit information.
It's complex, but its tasks are well defined.
Either the truth is too fluid and complex to define or it remains opaque to anyone not directly involved in manipulating events.
Analysis of the velocity behavior at the different distances from macrofracture zone shown that it is complex and it is difficult to define the deformation stage using interval velocity only.
Due to small radius (0.6 A), the Li+ ions are highly mobile, so they can create as well as destroy the complexes easily [29, 31], and because of that, it is difficult to define complex structure involving lithium perchlorate salt that was formed during the curing reaction.
Frequently, in these experiments, it is necessary to define complex protein mixtures.
It was difficult to define a complex product that could be made in large volume since everything tended to become unique above the individual gate level.
As many recent efforts argue that organizational culture is the key to organizational excellence, it is critical to define this complex concept in a manner that will provide a common frame of reference for practitioners and researchers.
It is clear that, for many complex traits, it is difficult to define one unified phenotype with the same underlying genetic risk factors, and that to do so may, in fact, be misleading.
However, it is increasingly recognized that for some complex endpoints, it is difficult to define "true" results, especially when the goal is the prediction of adverse outcomes in humans.
The frozen soil engineering system is such a complex synthesis that it is difficult to define the complete physical process in this system.
