Recently, deep learning techniques to learn effective feature representations have swept a variety of computer vision tasks including face recognition with illumination, poses, and expressions problems.
To bypass the early TCR expression problem, one group has produced a model in which the TCRα chain is not expressed until the DP stage of development [5].
While the extreme nature of this expression problem prevented characterization of α2AP(13-109 -HSA, α2AP(13-73 -HSA was purified and shown to have been proteolyzed at the L69-V70 bond.
The formation of heteromorphic sex chromosomes has occurred independently several times in evolution, and their formation is accompanied by an expression problem that must be solved by the co-evolution of mechanisms that compensate this unbalance.
Most probably, the adaptation of other widely used reporter genes to C. reinhardtii (like the genes for the fluorescent proteins GFP and YFP) will require a general solution to the transgene expression problem in Chlamydomonas.
This suggests that a significant fraction of His BCNT might form complexes with cellular component(s) and/or undergo dimerization that would block access to the N-terminal His-tag for affinity binding, although we are unable to exclude the possibility of a general expression problem concerning the production of intrinsically disordered proteins.
The highest classification accuracy was obtained in 9 out of the 11 tested gene expression problems.
More frighteningly, it seems that mammals can be born even when gene expression problems are significant.
Extensive works have been carried out towards the illumination, pose, and expression problems and also get some excellent results [10 12].
The heterologous expression of these genes in the yeasts S. cerevisiae and K. lactis produced very unstable laccases with expression problems (Pezzella et al. 2009).
The face recognition experiment using the proposed face representation approach considered other unconstrained conditions, which included usual pose, illumination, and expression problems.
