Single flap approach combined with periosteal pedicle flap as a regenerative procedure: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Single flap approach (SFA) is a validated procedure for obtaining clinical attachment gain and pocket closure when applied to deep intraosseous defects. However, the presence of an interdental crater as well as the tooth location were associated with a lower rate of primary intention closure, possibly jeopardizing the outcome of the

Crater Detection Dependence on Resolution, Incidence Angle, Emission Angle, and Phase Angle

Geophysical Research Letters
Impact crater population detection and measurement is critical to understanding solar system bodies and dynamics. However, the ability to detect all possible craters under different lighting and camera geometries has not been systematically studied ...

Degenerate optimization problems of economy and power engineering

Nuclear Energy and Technology, 2015
Optimization of large economy and power engineering systems leads to degenerate solutions of a high dimensionality. This is a very strong mathematical complication.

Comet and Meteorite Traditions of Aboriginal Australians

, 2014
Of the hundreds of distinct Aboriginal cultures of Australia, many have oral traditions rich in descriptions and explanations of comets, meteors, meteorites, airbursts, impact events, and impact craters. These views generally attribute these phenomena to

Multi‐Dimensional Conductive Nanocomposites for Flexible Electronics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Multi‐dimensional conductive nanocomposites integrate 0D, 1D, and 2D nanomaterials through spatial structure regulation and interface engineering, achieving “1 + 1 > 2” synergistic effects. By leveraging 0D filling to reduce contact resistance, 1D bridging to construct continuous conductive paths, and 2D supporting to enhance mechanical stability ...

Are the detection and dimensions of peri‐implant buccal bone defects influenced by different implant materials and their location? An experimental cone‐beam computed tomography study

Journal of Periodontology, EarlyView.
Abstract Background The aim of this study is to evaluate the impact of different implant materials and arrangements within the field of view (FOV) and exomass on the diagnostic accuracy and image quality of cone‐beam computed tomography (CBCT) for the detection of peri‐implant buccal bone defects of various sizes. Methods A total of 120 CBCT scans with

A new chronology for the Moon and Mercury

, 2009
In this paper we present a new method for dating the surface of the Moon, obtained by modeling the incoming flux of impactors and converting it into a size distribution of resulting craters.

Mechanisms of Laser Ablation in Liquids and Their Impact on the Efficiency of Nanoparticle Generation

Laser &Photonics Reviews, EarlyView.
Laser ablation in liquid enables nanoparticle synthesis from diverse materials but remains less energy‐efficient than ablation in air. This study quantifies the absorption‐corrected ablation efficiency and experimentally confirms redeposition as the key loss mechanism using pump‐probe microscopy.
