TL;DR: In this paper, the InfraRed Flux Method was used to obtain stellar properties, such as masses, radii, effective temperatures, bolometric fluxes and distances for field stars in a self-consistent manner.
Abstract: Accurately determining the properties of stars is of prime importance for characterizing stellar populations in our Galaxy. The field of asteroseismology has been thought to be particularly successful in such an endeavor for stars in different evolutionary stages. However, to fully exploit its potential, robust methods for estimating stellar parameters are required and independent verification of the results is mandatory. With this purpose, we present a new technique to obtain stellar properties by coupling asteroseismic analysis with the InfraRed Flux Method. By using two global seismic observables and multi-band photometry, the technique allows us to obtain masses, radii, effective temperatures, bolometric fluxes, and hence distances for field stars in a self-consistent manner. We apply our method to 22 solar-like oscillators in the Kepler short-cadence sample, that have accurate Hipparcos parallaxes. Our distance determinations agree to better than 5%, while measurements of spectroscopic effective temperatures and interferometric radii also validate our results. We briefly discuss the potential of our technique for stellar population analysis and models of Galactic Chemical Evolution.

TL;DR: The Mesozoic large igneous province (LIP) of Patagonia (southern South America) has been investigated by the 40Ar/39Ar method as mentioned in this paper, which shows a regular decreasing of ages from the ENE (187 Ma) to the WSW (144 Ma) along about 650 km, apparently related to the tectonic structure in half-grabens oriented NNW-SSE.

TL;DR: This study confirmed the feasibility of using a screening questionnaire for eliciting population-based estimates of OA in a multiregional sample in France, where it increases with age and is greater among women above the age of 50.

TL;DR: Examination of pejorative markers for clinical conversion showed that sex, number of T2 lesions, presence of oligoclonal bands, and IgG index were not statistically different in patients with MS determined by MRI compared with clinically definite MS.
Abstract: Background Subclinical demyelinating lesions may occur in the brains of asymptomatic individuals. Objective To describe the clinical and magnetic resonance imaging (MRI) follow-up of patients with subclinical demyelinating lesions that fulfill the Barkhof/Tintore criteria. Design Prospective study. Setting University-affiliated teaching hospitals. Patients Fifty-three women and 17 men with subclinical demyelinating lesions (mean age, 35.63 years). Main Outcome Measures Cerebrospinal fluid, MRI, and visual evoked potential measurements. Methods All patients underwent their first brain MRI for various medical problems that were not suggestive of multiple sclerosis (MS). The patients' physicians proposed that they undergo paraclinical studies (blood, cerebrospinal fluid, and visual evoked potential analysis) and follow-up with MRI. Results Twenty-three patients (33%) had clinical conversion: 6 to optic neuritis, 6 to myelitis, 5 to brainstem symptoms, 4 to sensitive symptoms, 1 to cerebellar symptoms, and 1 to cognitive deterioration. The mean time between the first brain MRI and the first clinically isolated syndrome was 2.3 years (range, 0.8-5.0 years). Twelve patients had been treated with immunomodulators after a clinically isolated syndrome. Examination of pejorative markers for clinical conversion showed that sex, number of T2 lesions, presence of oligoclonal bands, and IgG index were not statistically different in patients with MS determined by MRI compared with clinically definite MS. Visual evoked potential abnormalities, young age, and gadolinium enhancement on follow-up MRI were more frequent in clinically definite MS than in MS determined by MRI. Conclusions In this cohort, we determined the rate of clinical conversion (33%) during a mean follow-up of 5.2 years. To our knowledge, this is the first clinically isolated syndrome cohort with preclinical follow-up. Early treatment of these patients with MS determined by MRI should be discussed.

TL;DR: This paper synthesises the existing methods applied to monitor P. oceanica meadows, identifies the most suitable techniques and suggests future research directions, and shows the interest of a practical guide that describes, in a standardized way, the most useful techniques enabling P. Oceanica meadow to be used as an environmental descriptor.
