A growing body of published work provides evidence of radiological methods, including multimodal magnetic resonance imaging and positron emission tomography, which may help noninvasively differentiate iNPH from AD or reveal concurrent AD pathology <i>in vivo</i>. Imaging methods detecting morphological changes, white matter microstructural changes, cerebrospinal fluid circulation, and molecular imaging have been widely applied in iNPH patients.

In case where the estimated pose error is large, a self-calibration process corrects the estimation error of the intrinsic camera parameters and the translation of the pose in order to improve the reconstruction.

The Navy and other military services provided the transportation, construction, and maintenance to make life and work possible on the ice. The scientific success and value of the IGY inspired a mechanism—the Antarctic Treaty of 1959—for a peaceful future focused on the cooperative pursuit of scientific knowledge. While imperfect and fragile, the treaty is still in force and, with continuing military and civilian support, scientific research in Antarctica prospers. All this was achieved in a remarkably short time, by disparate, thinly acquainted, mutually wary cultures—military, scientific, and diplomatic.
