Eclipsing binaries in the MACHO database: New periods and classifications for 3031 systems in the Large Magellanic Cloud [PDF]

, 2007
Eclipsing binaries offer a unique opportunity to determine fundamental physical parameters of stars using the constraints on the geometry of the systems. Here we present a reanalysis of publicly available two-color observations of about 6800 stars in the

Micro Elastofluidics for Tuneable Droplet Merging

Advanced Materials Technologies, EarlyView.
This technical paper provides a proof of concept of fully flexible and stretchable microfluidic technology for tuneable droplet mixing and merging. The phenomenon is justified through theoretical, numerical and experimental studies. ABSTRACT Droplet microfluidics enables precise handling of discrete fluid volumes at the microscale, with broad ...

Eclipsing binary stars in the era of massive surveys First results and future prospects

EPJ Web of Conferences, 2017
Our thinking about eclipsing binary stars has undergone a tremendous change in the last decade. Eclipsing binary stars are one of nature’s best laboratories for determining the fundamental physical properties of stars and thus for testing the predictions

Eclipsing binary stars with a delta Scuti component [PDF]

, 2017
Eclipsing binaries with a δ Sct component are powerful tools to derive the fundamental parameters and probe the internal structure of stars. In this study, spectral analysis of six primary δ Sct components in eclipsing binaries has been performed. Values

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

Advanced Science, EarlyView.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

Relations between the absolute characteristics of the components of the different-type eclipsing binary systems

Odessa Astronomical Publications, 2017
By using our compiled catalogues of the characteristics of 303 eclipsing binaries with the constant and variable orbital periods, we computed the «Mass-Luminosity», «Mass-Radius» and «Mass- Temperatures relationships.

Expected Large Synoptic Survey Telescope (LSST) Yield of Eclipsing Binary Stars

, 2011
In this paper we estimate the Large Synoptic Survey Telescope (LSST) yield of eclipsing binary stars, which will survey ~20,000 square degrees of the southern sky during the period of 10 years in 6 photometric passbands to r ~ 24.5.

Planet Candidates from K2 Campaigns 5-8 and Follow-Up Optical Spectroscopy [PDF]

, 2017
We present 151 planet candidates orbiting 141 stars from K2 campaigns 5-8 (C5-C8), identified through a systematic search of K2 photometry. In addition, we identify 16 targets as likely eclipsing binaries, based on their light curve morphology.

Beyond Transconductance: Cell‐Polymer Coupling Determines Fidelity in Action Potential Recording via Electrolyte‐Gated Polymer Transistors

Advanced Science, EarlyView.
High electrical performance alone does not guarantee efficient bioelectronic signal transduction. Despite excellent mixed ionic‐electronic conduction, recordings from cardiomyocytes reveal that p(g2T‐TT)‐based OECTs predominantly transduce field potential FP‐like signals due to weak cell‐polymer coupling.

The Investigation of 84 TESS Totally Eclipsing Contact Binaries

The Astronomical Journal
Based on the eclipsing binary catalog provided by A. Prša et al., 84 totally eclipsing contact binaries with stable light curves were selected. The Transiting Exoplanet Survey Satellite light curves of these 84 targets were studied using the Physics Of ...
