Laser is considered basically effective for treating periodontal diseases because of its excellent physical properties namely ablation, hemostasis, bacterial killing and cell stimulation. The current laser application mainly used for the treatment of periodontitis is high-power laser ablation (HLLT). Laser ablation of diseased periodontal tissues using the HLLT is widely performed, partly expec...

A variety of fundamental astrophysical science topics require the determination of very accurate photometric redshifts (photo-z). A wide plethora of methods have been developed, based either on template models fitting or on empirical explorations of the photometric parameter space. Machine-learning-based techniques are not explicitly dependent on the physical priors and able to produce accurate...

We introduce the concept of hybrid widgets, which consist of a digital object on an interactive display surface, and a physical handle attached to it. We describe two implementations of this concept, both for the interaction with digital photo collections on an interactive tabletop, and discuss how the combination of a physical and a digital part in the hybrid widget supports interaction and so...

Mesoporous silica, specifically SBA-15, acid-treated multi-walled carbon nanotubes and a hybrid nanocomposite of SBA-15 coated onto the sidewalls acid-treated multi-walled carbon nanotubes (CNTs) were prepared and used as supports for anatase TiO2. Sol-gel methods were adapted for the synthesis of selected supports and for coating the materials with selected wt% loading of titania. Physical and...

I discuss general unified formulas for resumming collinear and soft contributions to QCD hard scattering cross sections at large x. Expansions of the resummed cross sections to next-to-next-to-next-to-leading order are also shown along with applications of the formalism. Presented at DPF 2004, Riverside, California, August 26-31, 2004.

An open edge of a simple polygon is the set of points in the relative interior of an edge. We revisit several art gallery problems, previously considered for closed edge guards, using open edge guards. A guard edge of a polygon is an edge that sees every point inside the polygon. We show that every simple non-starshaped polygon admits at most one open guard edge, and give a simple new proof tha...

The 64-channel Multianode Photo Multiplier has been evaluated as a possible choice for the photo detectors of the LHCb Ring Imaging Cherenkov detector. Contributed to the Proceedings of the 30 International Conference on High Energy Physics, 7/27/2000—8/2/2000, Osaka, Japan

abstract various studies carried out on different photo anthropometry, but each one had some deficiencies which during the years they have been resolved. the objective of this paper is to test the efficiency of two-dimensional image processing software in photo anthropometry of hand. in this applied research, 204 office workers and industrial workers were selected. their hands were measured by ...
