Facts in artifacts

Journal of Oral and Maxillofacial Pathology, 2013
Examination of microscopic sections of animal tissues reveals facts which are not always related to its normal histology or pathology. Processing of tissue specimens consists of lengthy procedures from the stage of surgical removal to the stained and mounted microscopic sections.

Behavior of a self-interstitial-atom type dislocation loop in the periphery of an edge dislocation in BCC-Fe

Nuclear Materials and Energy, 2016
The behavior of the dislocation loop of a self-interstitial atom (SIA) near an edge dislocation and its conservative climb process were modeled in body-centered cubic Fe by incorporating loop rotation.

Quality control in resting-state fMRI: the benefits of visual inspection

Frontiers in Neuroscience, 2023
BackgroundA variety of quality control (QC) approaches are employed in resting-state functional magnetic resonance imaging (rs-fMRI) to determine data quality and ultimately inclusion or exclusion of a fMRI data set in group analysis.

Modal Planning for Cooperative Non-Prehensile Manipulation by Mobile Robots

Applied Sciences, 2019
If we define a mode as a set of specific configurations that hold the same constraint, and if we investigate their transitions beforehand, we can efficiently probe the configuration space by using a manipulation planner.

Contrast-to-noise ratios of different dental restorative materials: An in-vitro cone beam computed tomography study

European Oral Research, 2020
Purpose In radiological views, strong beam hardening and streaking artifacts occur due to high-density structures and polyenergetic X-ray beams, and these lead to misdiagnosis. This study was performed in vitro to compare the contrast-to-noise ratio (CNR)
