Sensors, Vol. 19, Pages 4241: An Energy-Efficient Redundant Transmission Control Clustering Approach for Underwater Acoustic Networks Sensors doi: 10.3390/s19194241 Authors: Gulnaz Ahmed Xi Zhao Mian Muhammad Sadiq Fareed Muhammad Zeeshan Fareed Underwater Acoustic Network (UAN) is an emerging technology with attractive applications. In such type of networks, the control-overhead, redundant inner-network transmissions management, and data-similarity are still very challenging. The cluster-based frameworks manage the control-overhead and redundant inner-network transmissions persuasively. However, the current clustering protocols consume a big part of their energy resources in data-similarity as these protocols periodically sense and forward the same information. In this paper, we introduce a novel two-level Redundant Transmission Control (RTC) approach that ensures the data-similarity using some statistical tests with an appropriate degree of confidence. Later, the Cluster Head (CH) and the Region Head (RH) remove the data-similarity from the original data before forwarding it to the next level. We also introduce a new spatiotemporal and dynamic CH role rotation technique which is capable to adjust the drifted field nodes because of water current movements. The beauty of the proposed model is that the RH controls the communications and redundant transmission between the CH and Mobile Sink (MS), while the CH controls the redundant inner-network transmissions and ...

Authors: Nagy P, Molnar B, Nemes B, Schupbach P, Windisch P Abstract The aim of this case series was the histologic evaluation of guided tissue regeneration utilizing deproteinized bovine bone mineral (DBBM) when regenerative surgery was combined with (test) or without (control) early orthodontic tooth movement. Core biopsy samples were harvested from previously defected sites after 9 months. The histologic section showed integration of DBBM particles in newly formed bone in the apical and middle thirds of the defect, while in the coronal part, graft materials were mainly embedded in connective tissues in the contr...

Authors: Al Balbeesi HO, Al Kawari HM, Al Tamimi AS, Al Mubarak I, Al Ibrahim KI, Divakar DD Abstract In the present study, the authors evaluated the association of canine impaction with different skeletal discrepancies in two planes of space (sagittal and vertical). Cephalometric and orthopantomographic radiographic images of 45 patients with one or more impacted canines were used in this retrospective study. Five radiographic morphologic parameters-ANB angle, canine angulation, angle between the Frankfort horizontal plane and the mandibular plane (FH-MP), Wits appraisal analysis, and axial inclination of the maxi...
