Some spectroscopic observations of visual binaries [PDF]
Astrophysics and Space Science, 1965 AbstractThe use of a coudé spectrograph for securing the high-resolution spectrograms necessary to follow the slow variations of radial velocity exhibited by visual binaries is discussed. Recent observations, using the spectrograph at the coudé focus of the Dominion Astrophysical Observatory’s 48-in. reflector, are then presented for the systems ofαUMa,

, 2015 We present relative astrometric measurements of visual binaries made in 2013 with the speckle camera PISCO at the 102-cm Zeiss telescope of Brera Astronomical Observatory, in Merate.

Multiplicity among Visual Binaries [PDF]
International Astronomical Union Colloquium, 1977 AbstractA brief review of the history of multiple-star discovery is followed by a discussion of selection effects, discovery probability, and detection techniques. The incidence of multiplicity and the properties of multiples in various samples of binaries are investigated.

The Census of Exoplanets in Visual Binaries
, 2021 While numerous exoplanets have now been uncovered in stellar binaries, the impact of companion stars on planet formation and evolution is still not understood. From the Gaia DR2 catalog and an extensive literature search, we compiled the largest list to date of planets orbiting stars in visual comoving binaries out to 200 pc, providing a broad overview

Is stellar multiplicity universal? Tight stellar binaries in the Orion nebula Cluster [PDF]
, 2018 We present a survey for the tightest visual binaries among 0.3–2 M⊙ members of the Orion nebula Cluster (ONC). Among 42 targets, we discovered 13 new 0.025–0.15 arcsec companions. Accounting for the Branch bias, we find a companion star fraction (CSF) in

Molecular Oncology, EarlyView.Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

, 2012 We present relative astrometric and photometric measurements of visual binaries made in 2008, with the 76-cm refractor of Cote d'Azur Observatory. Our observing list contains orbital couples as well as binaries whose motion is still uncertain.

Molecular Oncology, EarlyView.There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...

Molecular Oncology, EarlyView.Trastuzumab‐deruxtecan, a HER2‐targeting antibody‐drug conjugate, shows promising antitumor activity in head and neck squamous cell carcinoma with low HER2 expression. In vitro and in vivo studies demonstrated dose‐dependent cell death and tumor growth reduction in low HER2‐expressing cell lines, which correlated with drug accumulation measured using a
