Calcifying cystic odontogenic tumor is an uncommon odontogenic neoplasm which is included in the heterogenous group of lesions under a broader description of Ghost cell odontogenic tumors. All these lesions have the presence of ghost cells as a common feature. Calcifying cystic odontogenic tumor is a unique lesion with variable biologic behaviour and found to occur with other odontogenic tumour...

This report presents the field data test of the improved autocorrelogram method using Friendswood RVSP Data. The improved migration method images the primary reflections, not the ghost reflections. The traces in the original common receiver gathers are autocorrelated after some preliminary processing. We separated the primary reflections from the surface-related ghost-reflections in the autocor...

In this study we have investigated a new method to reduce the number of ghosts produced by a medium pulse repetition frequency (PRF) MTI radar incorporating ambiguity resolution techniques. The paper introduces the concepts behind ambiguity resolution and ghost reduction techniques. Simulations have been carried out to verify the performance of the developed ghost reduction algorithm and the re...

Having considered current reports concerning plagiarisms taking place in the global science community, the authors decided to address the principal reasons, which lead to these illegalities. In recent years, misconduct in research, such as plagiarism, fabrication, falsification, guest author, ghost author, self-citation, etc. have been increasing significantly in scientific papers, proving a la...

MOTIVATION Protein interaction networks provide an important system-level view of biological processes. One of the fundamental problems in biological network analysis is the global alignment of a pair of networks, which puts the proteins of one network into correspondence with the proteins of another network in a manner that conserves their interactions while respecting other evidence of their ...

PURPOSE MR measurements from an echo-planar imaging (EPI) sequence produce Nyquist ghost artifacts that originate from inconsistencies between odd and even echoes. Several reconstruction algorithms have been proposed to reduce such artifacts, but most of these methods require either additional reference scans or multipass EPI acquisition. This article proposes a novel and accurate single-pass E...

We study the hierarchy of hidden space-time symmetries of noncritical strings in RNS formalism, realized nonlinearly. Under these symmetry transformations the variation of the matter part of the RNS action is cancelled by that of the ghost part. These symmetries, referred to as the α-symmetries, are induced by special space-time generators, violating the equivalence of ghost pictures. We classi...

Experienced surgeons commonly mentor trainees as they move through their initial learning curves. During robot-assisted minimally invasive surgery, several tools exist to facilitate proctored cases, such as two-dimensional telestration and a dual surgeon console. The purpose of this study was to evaluate the utility and efficiency of three, novel proctoring tools for robot-assisted minimally in...

Two candidates for “almost-invariant” toroidal surfaces passing through magnetic islands, namely quadratic-flux-minimizing (QFMin) surfaces and ghost surfaces, use families of periodic pseudo-orbits (i.e. paths for which the action is not exactly extremal). QFMin pseudo-orbits, which are coordinate-dependent, are field lines obtained from a modified magnetic field, and ghost-surface pseudo-orbi...
