Therefore, the understanding of machining mechanisms of cerium is challenging for its complex deformation behavior.
Mimicking the mechanical properties at large deformation is challenging because of the inherent difference between the mechanical behaviors of polymeric materials and that of human tissues.
The interpretation of the exact geotechnical significance of small, radar sensed ground surface deformations is challenging, especially where ground truth is lacking.
This presents a particular challenge for deformation measurements, due to the notable number of episodes that have been observed at distance from Holocene volcanoes, which would nonetheless be associated with that volcano in the record (starred volcanoes in Table 2).
For densely forested areas, except for fault creeps, it remains challenging to detect long-wavelength interseismic deformation, although there have been some successful reports (e.g., Grandin et al. 2012; Huang et al. 2016).
As a result, it is required to reconstruct these mesh deformations beforehand, which is challenging without some sort of supporting 3D information.
The detection of acoustic signals originating from the deformation of the material is challenging since PE samples strongly attenuate ultrasonic waves.
Compared with traditional sparse representation-based trackers (e.g., L1APG, MTT, ASLA, LSK, and SST), our tracker outperforms in a wide range of challenging scenarios, especially when occlusion, rotation, and deformation occurs.
The determination of absolute deformation potentials (ADPs) has proved challenging for some time, even for close-packed elemental and binary semiconductors.
