Developments in ROOT I/O and trees [PDF]
J.Phys.Conf.Ser.119:042006,2008, 2009 For the last several months the main focus of development in the ROOT I/O package has been code consolidation and performance improvements. Access to remote files is affected both by bandwidth and latency. We introduced a pre-fetch mechanism to minimize the number of transactions between client and server and hence reducing the effect of latency.

HL-LHC Analysis With ROOT [PDF]
arXiv, 2022 ROOT is high energy physics' software for storing and mining data in a statistically sound way, to publish results with scientific graphics. It is evolving since 25 years, now providing the storage format for more than one exabyte of data; virtually all high energy physics experiments use ROOT. With another significant increase in the amount of data to

An improved technique for the evaluation of root canal preparation
Journal of Endodontics, 1999 A device and a method are described for the simultaneous in vitro evaluation of several important parameters of root canal preparation, including root canal cleanliness, straightening, changes in root canal diameter, working safety (loss of working length, apical blockage, instrument fracture, and apical perforation), measurement of apically extruded ...

Teeth And Root Canals Segmentation Using ZXYFormer With Uncertainty Guidance And Weight Transfer [PDF]
arXiv, 2023 This study attempts to segment teeth and root-canals simultaneously from CBCT images, but there are very challenging problems in this process. First, the clinical CBCT image data is very large (e.g., 672 *688 * 688), and the use of downsampling operation will lose useful information about teeth and root canals.

Root‐canal preparation with FlexMaster: canal shapes analysed by micro‐computed tomography [PDF]
International Endodontic Journal, 2003 AbstractAim To evaluate the relative performance of FlexMaster nickel–titanium instruments shaping maxillary molar root canals in vitro.Methodology Extracted human maxillary molars were scanned, before and after root‐canal shaping, with FlexMaster, employing micro‐computed tomography (µCT) at a resolution of 36 µm.
