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.

Cytoskeleton, EarlyView.ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

A Photometric and Spectroscopic Investigation of 11 TESS Eclipsing Contact Binaries
The Astrophysical JournalBy cross-matching the eclipsing binary catalog provided by A. Prša et al. with Large Sky Area Multi-Object Fiber Spectroscopic Telescope medium-resolution spectra, we obtained 11 targets.

Massive binaries in the vicinity of Sgr A*
, 2013 A long-term spectroscopic and photometric survey of the most luminous and massive stars in the vicinity of the super-massive black hole Sgr A* revealed two new binaries; a long-period Ofpe/WN9 binary, GCIRS 16NE, with a modest eccentricity of 0.3 and a ...

Extragalactic eclipsing binaries: astrophysical laboratories [PDF]
New Astronomy Reviews, 2004 Eclipsing binaries (EBs) have long been known for providing accurate stellar fundamental properties, such as masses and radii. These are obtained from the modeling of light and radial velocity curves and, with input data of good quality, uncertainties of a few percent in the components’ physical properties are now routinely achieved.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Research addressing the microfoundations of corporate social performance (CSP) in small and medium‐sized enterprises (SMEs) remains sparse. This paper aims to investigate how SME managers' ethical ideology affects CSP and examines the mediating role of their CSR orientation (CSRO): economic, legal, ethical, and philanthropic.

Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics [PDF]
, 2012 Russell (1948) famously described eclipses as the "royal road" to stellar astrophysics. From photometric and spectroscopic observations it is possible to measure the masses and radii (to 1% or better!), and thus surface gravities and mean densities, of ...

Pest Management Science, EarlyView.The study shows ancestral dietary restriction in Phytoseiulus persimilis produces persistent, sex‐specific, multi‐generational effects on survival and body size, with stronger maternal than paternal lineage influences despite nutritional recovery. Abstract BACKGROUND Transgenerational phenotypic plasticity (TGP) allows environmental effects to persist ...

Collaboration post‐acquisition: The role of acquirers' motives
Strategic Management Journal, EarlyView.Abstract Research Summary What role do collaborations with a target's partners play in an acquisition, and how do these collaborations evolve post‐acquisition? Research suggests that these collaborations are an important reason to acquire but often diminish post‐acquisition. But if they tend to diminish, why are they a reason to acquire?

Precision Timing of Eclipsing Binaries from TESS Full Frame Images: Method and Performance
The Astrophysical JournalSeveral hundreds of thousands of eclipsing binaries (EBs) are expected to be detected in the Transiting Exoplanet Survey Satellite (TESS) full frame images (FFIs).
