Low-temperature synthesis of polycyclic aromatic hydrocarbons in Titan’s surface ices and on airless bodies

open access: yesScience Advances, 2019
Model ices related to Titan’s surface show that polycyclic aromatic hydrocarbons are not solely formed in Titan’s atmosphere. Titan’s equatorial dunes represent the most monumental surface structures in our Solar System, but the chemical composition of ...

Von Economo Neuron Loss in Frontotemporal Dementia: A Meta‐Analysis of Neuropathological Studies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Von Economo neurons (VENs) have been reported to be vulnerable to neurodegeneration in frontotemporal dementia (FTD), particularly the behavioral variant (bvFTD), but these findings have not been systematically assessed across independent brain banks.

Ultrasonography Compared With Computed Tomography in Identifying Thoracic Aortic Aneurysms in Patients With Giant Cell Arteritis

open access: yesArthritis Care &Research, EarlyView.
Objective The objectives of this study were to evaluate the correlation and agreement between ultrasonography and computed tomography (CT) in measuring ascending aorta diameter in patients with giant cell arteritis (GCA) and to investigate the development of new ascending aortic aneurysms in patients with newly diagnosed GCA.

Performance Characteristics of Anti–Collagen II Antibodies in Relapsing Polychondritis and Related Diseases: Prospective Analysis, Systematic Review, and Meta‐Analysis

open access: yesArthritis Care &Research, EarlyView.
Objective Relapsing polychondritis (RP) is a rare disease defined by recurrent cartilaginous inflammation. Anti–collagen II (Col2) antibodies have been proposed as a diagnostic biomarker for RP, but their performance characteristics are not well defined.

Use of Steel Slag as Coarse Aggregate for the Production of Pervious Concrete

open access: yesJournal of Sustainable Development of Energy, Water and Environment Systems, 2014
Pervious concrete is a type of concrete with significantly increased water permeability, ensuring increased rates of drainage of rainfall. The high porosity is achieved by removing a large percentage of fine aggregates from the mix.

Superrotation on Venus, on Titan, and Elsewhere

open access: yesAnnual Review of Earth and Planetary Science, 2018
The superrotation of the atmospheres of Venus and Titan has puzzled dynamicists for many years and seems to put these planets in a very different dynamical regime from most other planets.

Retractions in Rheumatology: Trends, Causes, and Implications for Research Integrity

open access: yesArthritis Care &Research, EarlyView.
Objective We aimed to describe the trends and main reasons for study retraction in rheumatology literature. Methods We reviewed the Retraction Watch database to identify retracted articles in rheumatology. We recorded the main study characteristics, authors’ countries, reasons for retraction, time from publication to retraction, and trends over time ...

Application of TITAN for Simulation of Particle Streaming in a Duct

open access: yesEPJ Web of Conferences, 2016
The TITAN hybrid deterministic transport code is applied to the simulation of particle streaming in a nuclear power plant duct. A simple model is used consisting of a concrete duct emerging from the pressure vessel with an isotropic surface source with a
