The early repair often poses technical difficulty in creating secure closure of not only the septal defect but also the left ventricular incision especially when the adjacent left ventricular wall was extensively involved in infarction.
Furthermore, the natural anatomical and physiological intricacies of the lymphatic network in the head and neck region pose technical difficulties in the case of preoperative lymphoscintigraphy and SLN mapping procedures.
But that posed technical difficulties: Because the number of naïve T cells against any given antigen is too low to measure, they had to resort to a transgenic mouse that produces only a single type of T cell, directed against a protein called H-Y, which sits on the surface of all cells in male mice.
Research work on the Book of the Dead has always posed technical difficulties thanks to the need to copy very long hieroglyphic texts.
Small subjects pose technical difficulties in obtaining samples required by research protocols, and human use protocols may be constraining.
This adds significant difficulties to conduct group-level analysis (such as statistical parametric mapping, SPM [8]) and poses technical challenges to perform atlas-based anatomical labeling and ROI analysis [9, 10] with minimal or no human intervention.
Bringing a live horse onstage, however, poses technical problems.
However, the low proportion of ffDNA present in maternal plasma still poses some technical difficulties related to sample stability during transport and DNA extraction methods.
But the valorization of underground spaces also poses many technical difficulties because these spaces are generally badly perceived by the urban populations, which attend primarily the basements of the cities to only move.
In contrast to the situation without volatility uncertainty, where classical wellposedness and comparison theorems for BSDEs are used by Becherer and Kentia (2017) to derive characterizations of valuations and hedges by standard BSDE, the case including volatility uncertainty poses more technical difficulties in using 2BSDEs.
