TL;DR: In this article, a new calibration of the surface brightness-colour relation of eclipsing binary stars gives a distance to the Large Magellanic Cloud that is precise to one per cent.
Abstract: In the era of precision cosmology, it is essential to determine the Hubble constant empirically with an accuracy of one per cent or better1. At present, the uncertainty on this constant is dominated by the uncertainty in the calibration of the Cepheid period–luminosity relationship2,3 (also known as the Leavitt law). The Large Magellanic Cloud has traditionally served as the best galaxy with which to calibrate Cepheid period–luminosity relations, and as a result has become the best anchor point for the cosmic distance scale4,5. Eclipsing binary systems composed of late-type stars offer the most precise and accurate way to measure the distance to the Large Magellanic Cloud. Currently the limit of the precision attainable with this technique is about two per cent, and is set by the precision of the existing calibrations of the surface brightness–colour relation5,6. Here we report a calibration of the surface brightness–colour relation with a precision of 0.8 per cent. We use this calibration to determine a geometrical distance to the Large Magellanic Cloud that is precise to 1 per cent based on 20 eclipsing binary systems. The final distance is 49.59 ± 0.09 (statistical) ± 0.54 (systematic) kiloparsecs. A new calibration of the surface brightness–colour relation of eclipsing binary stars gives a distance to the Large Magellanic Cloud that is precise to one per cent.

TL;DR: The most unstable compound in tested condition was myricetin, and the higher number of hydroxyl groups promote degradation of flavonoids, whereas sugar moiety and methoxyl groups protect flavonoid of degradation during microwave and ultrasonic assisted extraction.

TL;DR: In this article, the authors demonstrate how marketing may benefit from neurophysiology by using electroencephalography and electromyography and monitoring skin conductance to detect differences in consumer reactions to slightly different marketing stimuli.
Abstract: This article demonstrates how marketing may benefit from neurophysiology. The authors discuss a particular research case concerning the analysis of a skin care product advertisement. Pretests of 2 versions of this TV ad revealed that, although the versions were almost identical, each of them generated significantly different impact. Their influence was assessed using both cognitive measures (benefits and key benefits recall) and behavioral measures (shelf test). The only difference between these 2 versions of the ad was in a single scene that contained a particular gesture by a female model. Of note, the gesture appeared to enhance the effectiveness of the ad. The authors tested whether neurophysiological measures can capture differences in consumer reactions to slightly different marketing stimuli. Indeed, by using electroencephalography and electromyography and by monitoring skin conductance, the authors were able to register significant differences in neurophysiological reactions to an altered scene, even though the difference was not consciously seen. The authors believe that neurophysiological measures soon will be widely acknowledged and used as a complimentary method in classical marketing research.

TL;DR: It is shown that satisfiability for the two-variable first-order logic FO2(~,<,+1) is decidable over finite and over infinite data words, where ~ is a binary predicate testing the data value equality and +1,< are the usual successor and order predicates.
Abstract: In a data word each position carries a label from a finite alphabet and a data value from some infinite domain. These models have been already considered in the realm of semistructured data, timed automata and extended temporal logics. It is shown that satisfiability for the two-variable first-order logic FO^2(~,\le,+1) is decidable over finite and over infinite data words, where i« is a binary predicate testing the data value equality and +1,\le are the usual successor and order predicates. The complexity of the problem is at least as hard as Petri net reachability. Several extensions of the logic are considered, some remain decidable while some are undecidable.
