Comparison between a handheld ultrasound device and a traditional ultrasound for performing transcranial sonography in patients with Parkinson's disease. [PDF]

Brain Behav, 2023
Graph 1. The receiver operating characteristic (ROC) curve. The area under the curve is 0.91 with a confidence interval (CI) of 95%: 0.84–0.97. The best substantia nigra cutoff value was 0.20 cm2. Sensitivity = 0.98 and specificity = 0.87. Abstract Objective The aim of this study is to compare a portable ultrasound (US) device and a traditional US for ...

Laboratory exploration of mineral precipitates from Europa's subsurface ocean. [PDF]

J Appl Crystallogr, 2021
Precipitation experiments from a model Europan ocean solution subjected to fast and slow freezing suggest that the highly hydrated Na–Mg sulfate phase Na2Mg(SO4)2·16H2O is one of the lowest‐temperature mineral phases likely to be stable on Europa's surface and may therefore be astrobiologically significant.The precipitation of hydrated phases from a ...

Lenticular Galaxies and Their Environments [PDF]

The Astrophysical Journal, 2009
It is widely believed that lenticular (S0) galaxies were initially spirals from which the gas has been removed by interactions with hot cluster gas, or by ram-pressure stripping of cool gas from spirals that are orbiting within rich clusters of galaxies.

Lenticular galaxies with UV-rings [PDF]

Astronomy Letters, 2011
By using the public UV imaging data obtained by the GALEX (Galaxy Ultraviolet Explorer) for nearby galaxies, we have compiled a list of lenticular galaxies possessing ultraviolet rings - starforming regions tightly confined to particular radial distances

Properties of Stellar Populations in Isolated Lenticular Galaxies [PDF]

Astrophysical Bulletin, 2014
In this paper we present the results of long-slit spectral observations for a sample of isolated lenticular galaxies, made with the SCORPIO and SCORPIO-2 spectrographs of the 6-meter BTA telescope of the SAO RAS.

Properties of the Photometric Components of Lenticular Galaxies [PDF]

Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012
After almost one century since their definition, the origin of lenticular galaxies is still a matter of debate. Several formation processes have been proposed in order to explain the wide variety of their observational properties. These properties could indicate that the class of lenticulars is a family formed by galaxies with different formations and ...

Bar fraction in lenticular galaxies: dependence on luminosity and environment [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2010
We present a study of bars in lenticular galaxies based on a sample of 371 galaxies from the SDSS-DR 7 and 2MASS in optical and near-infrared bands, respectively.

S-PLUS: LEnticular Galaxies in Stripe 82 (LEGS82) [PDF]

Anais da Academia Brasileira de Ciências, 2021
This work is a Brazilian-Indian collaboration. It aims at investigating the structural properties of Lenticular galaxies in the Stripe 82 using a combination of S-PLUS (Southern Photometric Local Universe Survey) and SDSS data. S-PLUS is a novel optical multi-wavelength survey which will cover nearly 8000 square degrees of the Southern hemisphere in ...

The role of siliciclastics in carbonate fabric diversity and preservation: A case study from the Neoproterozoic carbonate − siliciclastic Horse Thief Springs Formation, Death Valley

Sedimentology, Volume 69, Issue 5, Page 2284-2318, August 2022., 2022
Abstract The sedimentary record of the Pahrump Group in Death Valley comprises well‐exposed successions of mixed carbonate and siliciclastic deposits. Despite the abundance of studies focussing on the depositional dynamics of mixed carbonate – siliciclastic deposition in the Phanerozoic, the record of similar Proterozoic examples is comparatively ...
