V, I CCD photometry of metal-rich bulge globular clusters: NGC 6553
TL;DR: In this article, the metal-rich Galactic bulge globular cluster NGC 6553 and an adjacent field region were analyzed using a VI CCD photometry of about 40,000 stars down to 23 mag.
Journal ArticleDOI
Integrated parameters of star clusters: a comparison of theory and observations
TL;DR: In this paper, the integrated magnitudes and colours for synthetic clusters have been obtained for the whole cluster population as well as for the main-sequence (MS) population of star clusters.
Journal ArticleDOI
Broad‐band optical polarimetric study of IC 1805
TL;DR: In this article, the authors presented the BVR broadband polarimetric observations of 51 stars belonging to the young open cluster IC 1805 and modelled and subtracted the foreground dust contribution from the maximum polarization (P max ) and colour excess [E (B - V)].

TL;DR: A meta-analysis of studies on association between methylenetetrahydrofolate reductase gene (MTHFR) C677T gene polymorphism and ischemic stroke suggests that MTHFR C677t genetic polymorphism is a probable risk of isChemic stroke.
Journal ArticleDOI
Quasi-periodic oscillations in XTE J0111.2-7317: highest frequency among the HMXB pulsars
TL;DR: In this paper, the authors reported the discovery of quasi-periodic oscillations (QPOs) in the high-mass X-ray binary (HMXB) pulsar XTE J0111.2-7317 during a transient outburst of the source in 1998 December.
