Mandibular Rotated Pediculated Flap: A Technique to Increase Peri-Implant Mucosa Thickness. [PDF]

J Esthet Restor Dent
ABSTRACT Objectives Peri‐implant soft tissue is considered critical for maintaining peri‐implant health, minimizing esthetic and biological complications, and promoting the long‐term stability of implant‐supported restorations. This article describes a straightforward and minimally invasive technique for augmenting the peri‐implant mucosa thickness (MT)

Parasympathetic Tone Selectively Modulates Electrogram Fragmentation and Spectral Properties in Right Atrial Ganglionated Plexi. [PDF]

J Arrhythm
Electrogram fragmentation and spectral EGMs features in GPs area are selectively modulated by parasympathetic tone, as demonstrated by high‐density right atrial mapping before and after vagal blockade. EGMs, bipolar atrial electrograms; GPs, ganglionated plexi; RA, right atrium.

Combining reverse Monte Carlo analysis of X-ray scattering and extended X-ray absorption fine structure spectra of very small nanoparticles. [PDF]

J Appl Crystallogr, 2023
Computing scattering intensity using the Debye scattering equation after binning interatomic distances avoids finite size artefacts and is efficient enough for simultaneous refinement of scattering data and extended X‐ray absorption spectra by reverse Monte Carlo simulations.Finite size effects in partial pair distribution functions generate artefacts ...

The devil is in the detail: Environmental variables frequently used for habitat suitability modeling lack information for forest-dwelling bats in Germany. [PDF]

Ecol Evol
Traditional habitat suitability models, relying on variables with coarse level of detail, may inadequately represent the complexities of specialized species. This study shows that habitat suitability modeling for forest specialist bat species can be improved by integrating more targeted data, such as tree species classification map and LiDAR‐derived ...

A Bayesian perspective on Biogen's aducanumab trial

Alzheimer's &Dementia, Volume 18, Issue 11, Page 2341-2351, November 2022., 2022
Abstract This perspective is a companion to a recent editorial on the use of Bayesian analysis in clinical research. We aim to introduce and highlight the relevance and advantages that Bayesian inference offers to clinical trials using the data on the amyloid antibody aducanumab presented at a Food and Drug Administration hearing in November 2020 as an

Structure of Needle Highlights Ecological Adaptability and Microevolution of Natural Populations of Cedrus atlantica in Morocco

International Journal of Forestry Research, Volume 2022, Issue 1, 2022., 2022
The study of morphological and anatomical characteristics of leaves is important for assessing the geographical variation of species. The ecological adaptability of forty individuals from four populations of Cedrus atlantica were studied, based on analysis of morphological and anatomical traits.

Algorithmic versus teacher‐led sequencing in a digital serious game and the development of second language reading fluency and accuracy

British Journal of Educational Technology, Volume 52, Issue 5, Page 1898-1916, September 2021., 2021
Abstract Recent years have seen a surge of calls for personalization of education. Automatised adaptivity in serious games has been advocated as a potential instantiation of such calls. Yet little is known about the extent to which personalised learning through automatised adaptivity poses an advantage for language learning over generalised teacher‐led
