Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

Periodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Radio weak gravitational lensing with VLA and MERLIN [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
We carry out an exploratory weak gravitational lensing analysis on a combined VLA and MERLIN radio data set: a deep (3.3 micro-Jy beam^-1 rms noise) 1.4 GHz image of the Hubble Deep Field North. We measure the shear estimator distribution at this radio sensitivity for the first time, finding a similar distribution to that of optical shear estimators ...

Weak lensing, dark matter and dark energy

, 2010
Weak gravitational lensing is rapidly becoming one of the principal probes of dark matter and dark energy in the universe. In this brief review we outline how weak lensing helps determine the structure of dark matter halos, measure the expansion rate of ...

Resolving the discrepancy between X-ray and gravitational lensing mass measurements for clusters of galaxies [PDF]

, 1997
We present a detailed comparison of mass measurements for clusters of galaxies using ASCA and ROSAT X-ray data and constraints from strong and weak gravitational lensing.

Gravitational lensing around Kehagias–Sfetsos compact objects surrounded by plasma

European Physical Journal C: Particles and Fields, 2019
We study the optical properties of the Kehagias–Sfetsos (KS) compact objects, characterized by the “Hořava” parameter $$\omega _{_{KS}}$$ ωKS , in the presence of plasma, considering its homogeneous or power-law density distribution.

Light deflection by Damour-Solodukhin wormholes and Gauss-Bonnet theorem

, 2018
In this paper, using the recent method proposed by Ono, Ishihara and Asada (OIA) who extend the idea of Gibbons and Werner to the stationary and axisymmetric case, we apply the Gauss-Bonnet theorem to the optical metric of the non-rotating and rotating ...

Weak Lensing of the CMB: Cumulants of the Probability Distribution Function [PDF]

, 2002
We discuss the real-space moments of temperature anisotropies in the cosmic microwave background (CMB) due to weak gravitational lensing by intervening large-scale structure. We show that if the probability distribution function of primordial temperature

Weak gravitational lensing in fourth order gravity [PDF]

Physical Review D, 2012
For a general class of analytic $f(R,R_{αβ}R^{αβ},R_{αβγδ}R^{αβγδ})$ we discuss the gravitational lensing in the Newtonian Limit of theory. From the properties of Gauss Bonnet invariant it is successful to consider only two curvature invariants between the Ricci and Riemann tensor.

Weak-lensing Mass Bias in Merging Galaxy Clusters

The Astrophysical Journal, 2023
Although weak lensing (WL) is a powerful method to estimate a galaxy cluster mass without any dynamical assumptions, a model bias can arise when the cluster density profile departs from the assumed model profile. In a merging system, the bias is expected
