(See images three and four. Notice how the 3s could not have been solved before, but are solved in the final).
As a promising candidate for lower power, higher density nonvolatile memories, severe challenges should be solved before integrating such ferroelectric materials into conventional CMOS technology [1,2].
The systemic toxicity associated with conventional therapy may thus be significantly reduced in targeted photodynamic therapy, but a series of problems should be solved before entering clinical practice, such as the toxicity of nanoparticles and how to eliminate them in the body after use [72].
Unfortunately, it appears that the Japanese government is split on the base issue, with some top officials flatly rejecting the notion that it will be solved before Air Force One touches down, while others, such as the foreign minister, seemingly acknowledging the inevitable Japanese acceptance of U.S. terms.
But many problems, such as metallic bipolar plate instead of graphite bipolar plate to decrease the cost, should be solved before its application.
Clearly, problems in the handling of iPSs, such as the use of viral vectors, teratoma formation, and lack of appropriate differentiation protocols, have to be solved before thinking about clinical applications.
Several problems must be solved before automating the proposed methods.
There was, however, another problem to be solved before sequencing analyses: which clones should be sequenced?
However, I am not suggesting that this structure should be solved before acceptance of this paper".
