Emergence Profile Angle Matters—Restoring Peri‐Implant Health by Adjusting Prosthetics—A Narrative Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To review the biological and clinical relevance of prosthetic design, specifically the emergence profile and restorative angle in influencing peri‐implant tissue health, and to illustrate how biologically driven prosthetic modifications can resolve inflammation and support peri‐implant stability.

IACT observations of gamma-ray bursts: prospects for the Cherenkov Telescope Array

, 2012
Gamma rays at rest frame energies as high as 90 GeV have been reported from gamma-ray bursts (GRBs) by the Fermi Large Area Telescope (LAT). There is considerable hope that a confirmed GRB detection will be possible with the upcoming Cherenkov Telescope ...

Limits on the validity of the thin-layer model of the ionosphere for radio interferometric calibration [PDF]

, 2016
For a ground-based radio interferometer observing at low frequencies, the ionosphere causes propagation delays and refraction of cosmic radio waves which result in phase errors in the received signal.

Territory, values, and health law in a devolved United Kingdom: examining the role of the gift in opt‐out organ donation

Journal of Law and Society, EarlyView.
Abstract Devolution since 1998 has seen administrations in England, Northern Ireland, Scotland, and Wales gain distinct powers over a range of policy fields, with health prominent among them. This poses two pressing questions for socio‐legal scholarship that we address in this article: to what extent are changing territorial arrangements significant ...

Prospects for determining air shower characteristics through geosynchrotron emission arrival times [PDF]

, 2010
Using simulations of geosynchrotron radiation from extensive air showers, we present a relation between the shape of the geosynchrotron radiation front and the distance of the observer to the maximum of the air shower.

Soft‐tissue volume augmentation during early, delayed, and late dental implant therapy: A systematic review and meta‐analysis on professionally determined esthetics and self‐reported patient satisfaction on esthetics

Periodontology 2000, EarlyView.
Abstract The objective of the study was to assess the effect of soft‐tissue volume augmentation during early, delayed, and late dental implant therapy in terms of professionally determined esthetics and self‐reported patient satisfaction on esthetics. For this, a comprehensive electronic literature search was performed to identify randomized clinical ...

Probing Fine-Scale Ionospheric Structure with the Very Large Array Radio Telescope

, 2009
High resolution (~1 arcminute) astronomical imaging at low frequency (below 150 MHz) has only recently become practical with the development of new calibration algorithms for removing ionospheric distortions.

Three‐dimensional digital quantitative analysis of periodontal and peri‐implant phenotype—A narrative review

Periodontology 2000, EarlyView.
Abstract 3D digital evaluation of the periodontal and peri‐implant tissue, including CBCT, intraoral scanning, optical surface scanning, and ultrasonography, is being used in the clinical arena with increasing frequency. Thus, to validate the utilization of 3D digital analysis for this purpose, a critical evaluation of the reliability of digital ...
