Moreover, the unpredictable locations of these failures may influence the regularity of the underlying topology, and a regular 2D mesh is likely to become irregular.
The advantage of this local likelihood estimate is that it smoothly downweights the influence of faraway observations, works for irregular sampling locations, and when designed appropriately, can trade bias and variance for reducing estimation error.
We also tested the difference in SPN size (diameter), border (regular or irregular), and location (upper, middle, or lower) according to selected patient's characteristics for both chest radiograph and CT.
The following histologic features were recorded for each tumor: size, laterality, histologic variant, and the presence or absence of additional features such as irregular border, location close to the capsule, extrathyroidal extension, satellite nodules, and isolated psammoma bodies.
Migration can be contrasted with emigration, which involves a change in location not necessarily followed by a return journey; invasion or interruption, both of which involve the appearance and subsequent disappearance of great numbers of animals at irregular times and locations; and range expansion, which tends to enlarge the distribution of a species, particularly its breeding area.
Most of these vascular anomalies can be distinguished from genuine nodules by their irregular shape, peripheral location, and different signal intensity on MRI.
The areas of enhancement in angiosarcoma often are central in location, irregular in shape, and have a lower attenuation than that of the aorta on at least one imaging phase[ 20, 21 ], although the enhancement progression may be centripetal.
In more general settings, wavelet techniques can be extended to handle the irregular distribution of sampling locations [153].
This effect is especially relevant when a user re-traces (parts of) the path he or she had previously travelled or lingers and moves around in an irregular pattern at single locations for extended periods of time.
