The main difficulty consists in the complexity of the dependence structure of a self-similar Gaussian process with nonstationary increments that does not have a representation based on the Wiener integral.
Part of the difficulty consists in obtaining a dephosphorylated protein, since Escherichia coli-produced kinases are heavily phosphorylated due to autophosphorylation and phosphorylation by E. coli kinases during expression (Enami and Ishihama, 1984).
One of the main difficulties consists in the lack of good priori estimates and appropriate compact embedding theorems for the usual Sobolev spaces.
Within the five criteria, the TAS-20 consists of 3 factors: difficulty identifying feelings (DIF); difficulty describing feelings (DDF); externally oriented cognitive style of thinking (EOT).
The Strength and Difficulties Questionnaire (SDQ) [ 41] consists of two parts.

The Strengths and Difficulties Questionnaire (SDQ [ 32]) consists of 25 items describing positive and negative attributes of children and adolescents that can be allocated to five subscales of five items each: emotional symptoms, conduct problems, hyperactivity-inattention, peer problems, and prosocial behavior.
The TAS-20 consists of three factor scales: Difficulty Identifying Feelings (DIF), Difficulty Describing Feelings (DDF) and Externally Oriented Thinking (EOT).
Cancer and its treatment, whether it is surgery, chemotherapy, or radiation therapy, is perceived as a crisis which consists of both the difficulty of integrating cancer diagnosis into a patient's life and the necessary adjustments to the different phases of the disease and treatment.
