The main difficulty of proposing a hypothesis for GA action is that we still do not quite know how the putative GA receptors open their ion channels on agonist binding, let alone how this opening can be modulated.
In recent years, interest has risen to use CAT in the context of online learning processes in order to adapt the difficulty level of proposed learning materials (Salcedo, Pinninghoff, & Contreras, 2005) or to perform summative evaluation of learning outcomes (Guzmán & Conejo, 2005).
Because of the difficulty of solving the proposed MINLP model due to the presence of binary variables and non-linear equations, we employ a simple method, also used by Almehdawe and Mantin (2010), to convert it to a pure non-linear program.
To overcome the difficulty of SVD, they proposed bilateral random projections.
To overcome the difficulty of data inconsistency, we propose a two-stage Delaunay-triangulation-based interpolation for fusing the LR image data.
In order to alleviate the difficulty of parallel programming, we propose a scheduler, which is part of a master slave RTOS, to efficiently manage the parallel programs running on a multi-processor core system.
To maximize terrains adaption ability, self-balancing capability, and obstacle getting over capability in unstructured disaster site, as well as reduce the difficulty of robot control, we proposed a semi-autonomous control system to realize this compound locomotion method for MAMFRs.
Based on the difficulty of the factorization problem, we proposed two ID-based multisignature schemes with distinguished signing authorities.
He noted the political difficulty of the proposed cuts — he has put forward similar ones before, only to have them rolled back by the Legislature — but said that after three years of tough budgets, there was little left to cut.
