HD 77407 and GJ 577: two new young stellar binaries detected with the Calar Alto Adaptive Optics system ALFA [PDF]
, 2004 We present the first results from our search for close stellar and sub-stellar companions to young nearby stars on the northern sky. Our infrared imaging observations are obtained with the 3.5 m Calar Alto telescope and the AO system ALFA. With two epoch

MAP-Elites for noisy domains by adaptive sampling [PDF]
, 2019 Quality Diversity algorithms (QD) evolve a set of high-performingphenotypes that each behaves as differently as possible. However,current algorithms are all elitist, which make them unable to copewith stochastic fitness functions and behavior evaluations.

Pumpkin phloem lectin genes are specifically expressed in companion cells. [PDF]
The Plant Cell, 1992 Pumpkin phloem exudate contains two abundant phloem proteins: PP1 is a 96-kD protein that forms polymeric filaments in vivo, and PP2 is a 48-kD dimeric lectin. Polyclonal antibodies raised against pumpkin phloem exudate were used to isolate several cDNAs corresponding to PP1 and PP2.

Epithelial–mesenchymal plasticity and circulating tumor cells: Travel companions to metastases [PDF]
Developmental Dynamics, 2017 Epithelial–mesenchymal transitions (EMTs) associated with metastatic progression may contribute to the generation of hybrid phenotypes capable of plasticity. This cellular plasticity would provide tumor cells with an increased potential to adapt to the different microenvironments encountered during metastatic spread.

Long-Term Adult Feline Liver Organoid Cultures for Disease Modeling of Hepatic Steatosis
Stem Cell Reports, 2017 Summary: Hepatic steatosis is a highly prevalent liver disease, yet research is hampered by the lack of tractable cellular and animal models. Steatosis also occurs in cats, where it can cause severe hepatic failure.

Sieve Elements and Companion Cells—Traffic Control Centers of the Phloem [PDF]
The Plant Cell, 1999 Of all the intricate cell–cell interactions in nature, those between the sieve element (SE) and its companion cell (CC) rank among the most complex and mysterious. Mature SEs are enucleate and retain only a highly degenerate cytoplasm, yet they can remain viable and functional for decades ([

Active DNA Demethylation in Plant Companion Cells Reinforces Transposon Methylation in Gametes [PDF]
Science, 2012 Intergenerational Transposable Shutdown Transposable elements (TEs) are a potential threat, especially to the germline genome. In many eukaryotes, TEs are shut down by DNA methylation and/or small-RNA–mediated silencing.
