The Infrared Surface Brightness Fluctuation Distances to the Hydra and Coma Clusters [PDF]
We present IR surface brightness fluctuation (SBF) distance measurements to NGC 4889 in the Coma cluster and to NGC 3309 and NGC 3311 in the Hydra cluster.

Spectroscopic Confirmation of the Dwarf Galaxies Hydra II and Pisces II and the Globular Cluster Laevens 1 [PDF]
We present Keck/DEIMOS spectroscopy of stars in the recently discovered Milky Way satellites Hydra II, Pisces II, and Laevens 1. We measured a velocity dispersion of 5.4 (+3.6 -2.4) km/s for Pisces II, but we did not resolve the velocity dispersions of ...

Nerve cell differentiation in hydra requires two signals [PDF]
Endogenous signals controlling nerve cell commitment in hydra were investigated using an assay for committed nerve precursors. Extracts of hydra tissue were prepared and tested for their ability to induce nerve cell commitment.

Hydra: Computer Vision for Online Data Quality Monitoring [PDF]
Hydra is a system utilizing computer vision for near real-time data quality monitoring. Currently operational across all of Jefferson Lab’s experimental halls, it reduces the workload of shift takers by autonomously monitoring diagnostic plots during ...

HYDRA: a Java library for Markov Chain Monte Carlo
Hydra is an open-source, platform-neutral library for performing Markov Chain Monte Carlo. It implements the logic of standard MCMC samplers within a framework designed to be easy to use, extend, and integrate with other software tools. In this paper, we

A Reference Genome from the Symbiotic Hydrozoan, Hydra viridissima
Various Hydra species have been employed as model organisms since the 18th century. Introduction of transgenic and knock-down technologies made them ideal experimental systems for studying cellular and molecular mechanisms involved in regeneration, body ...

Hydra’s Lasting Partnership with Microbes: The Key for Escaping Senescence?
Aging results from a complex interplay between genetic endowment and environmental exposures during lifetime. As our understanding of the aging process progresses, so does the need for experimental animal models that allow a mechanistic understanding of ...

Characterization of interstitial stem cells in hydra by cloning [PDF]
A procedure has been developed for cloning interstitial stem cells from hydra. Clones are prepared by introducing small numbers of viable cells into aggregates of nitrogen mustard-inactivated host tissue.
