The urban morphological system, developed over multiple phases, exhibits complex cross-scale characteristics, with significant scale discrepancies among morphological elements at the same ground strap hierarchical level, which suggests that the cross-scale sliding model holds the potential to reveal additional characteristics of urban morphology.Th
T cells often make sequential contacts with multiple DCs in the lymph nodes and are likely to be equipped with mechanisms that allow them to sum up the successive signals received.We found that a period of stimulation as short as two hours could imprint on a T cell a "biochemical memory" of that activation signal that persisted for several hours.Th
