ON THE MASS-RATIO OF THE ECLIPSING BINARIES OF W UMa TYPE

open access: yesOdessa Astronomical Publications, 2017
The discrepancy between the photometric and spectroscopic mass-ratio in W UMa-type systems is examined by using all the available mass-ratio data derived by modern techniques from photoelectric and radial velocity curves. The new additional data confirm,

The frequency of planets in multiple systems

open access: yes, 2007
The frequency of planets in binaries is an important issue in the field of extrasolar planet studies, because of its relevance in estimating of the global planet population of our Galaxy and the clues it can give to our understanding of planet formation ...

Precision‐Optimised Post‐Stroke Prognoses

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Current medicine cannot confidently predict who will recover from post‐stroke impairments. Researchers have sought to bridge this gap by treating the post‐stroke prognostic problem as a machine learning problem, reporting prediction error metrics across samples of patients whose outcomes are known.

Symbiotic Stars: Observations Confront Theory

open access: yesOpen Astronomy, 2012
In this paper, I present and discuss some recent observational results which may have important implications for our understanding of late phases of binary evolution.

A stochastic Monte Carlo approach to model real star cluster evolution, II. Self-consistent models and primordial binaries

open access: yes, 1999
The new approach outlined in Paper I (Spurzem \& Giersz 1996) to follow the individual formation and evolution of binaries in an evolving, equal point-mass star cluster is extended for the self-consistent treatment of relaxation and close three- and four-

Binary Cumulants

open access: yesAdvances in Applied Mathematics, 2000
AbstractThe binary cumulant is defined for joint probability distributions on binary sequences of finite length. The binary cumulant is bounded, in magnitude, by unity, and is shown to vanish if there exists any bipartition of the letter positions into statistically independent blocks.

Detecting rs‐fMRI Networks in Disorders of Consciousness: Improving Clinical Interpretability

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Preserved resting‐state functional MRI (rs‐fMRI) networks are typically observed in Disorders of Consciousness (DOC). Despite the widespread use of rs‐fMRI in DOC, a systematic assessment of networks is needed to improve the interpretability of data in clinical practice.

SBS 0802+529: A New Variable Star from the Second Byurakan Survey

open access: yesOpen Astronomy, 2012
A new emission line star was discovered on the plates of the Second Byurakan Survey (SBS). the follow up spectroscopy demonstrated that the object had a spectrum dominated by a late-type giant star with superposed hydrogen emission lines.

LONG-TERM ACTIVITY CHANGES OF UV PISOIUM

open access: yesOdessa Astronomical Publications, 2017
UV Psc has been observed since 1976 at the Ankara and Ege University Observatories. Mean light curves in B and V colours obtained using the maxima levels of observed light curves of the system.

Limits of Binaries That Can Be Characterized by Gravitational Microlensing

open access: yes, 2008
Due to the high efficiency of planet detections, current microlensing planet searches focus on high-magnification events. High-magnification events are sensitive to remote binary companions as well and thus a sample of wide-separation binaries are ...
