Cliff rescues are difficult, dangerous and time-consuming operations which often involve coordination with the coastguard and other emergency services.
The investigation, which involved coordination with police agencies and diplomats in 33 countries, was described by law enforcement officials as one of the most complicated international white-collar cases in recent memory.
People who have been hunting for weapons in Iraq have said that Mr. Kay has been frustrated over the lack of progress in the search, initially over problems involving coordination with military commanders charged in some cases with detaining the very Iraqis whose cooperation Mr. Kay's team was seeking.
The trial of his co-defendants is set to begin on July 2. The case involved coordination with Obama's Financial Fraud Enforcement Task Force, which was created in 2009.
Getting this far has been a daunting bureaucratic undertaking, involving coordination with the Rose Bowl, the city of Pasadena and LAXART, a nonprofit arts organization that is helping with fundraising.
Heat emergency plans are also implemented at the local level but involve coordination with state agencies and other nonprofit groups.
As described in the Materials and Methods, refinement efforts led to a model with two partially occupied Mg2+ sites that are 0.7 Å apart: one involving coordination primarily with E96 (A site, 0.35 occupancy) and the second involving coordination with both D70 and E96 (B site, 0.65 occupancy).
This novel plasticity observed for E96 provides a possible mechanism for binding of Mg2+ in three different positions all involving coordination with E96, two observed in our APE1 Mg2+ structure and the third in the product DNA complex structure (4IEM).
The designations of A and B in this context refer to alternate conformations for the Mg2+ in our crystal structure and should not be confused with previous reports in which a second proposed binding site involving coordination with D210, N212, and H309 was referred to as the B site.
