To better understand telomere biology in budding yeast, we have performed systematic suppressor/enhancer analyses on yeast strains containing a point mutation in the essential telomere capping gene CDC13 (cdc13-1) or containing a null mutation in the DNA damage response and telomere capping gene YKU70 (yku70Δ). We performed Quantitative Fitness Analysis(More)
High-throughput screens comparing growth rates of arrays of distinct micro-organism cultures on solid agar are useful, rapid methods of quantifying genetic interactions. Growth rate is an informative phenotype which can be estimated by measuring cell densities at one or more times after inoculation. Precise estimates can be made by inoculating cultures onto(More)
A range of small, long-life ultrasonic fish tags is described and their use illustrated with an improved system of fixed hydrophone tracking stations. A boat-mounted hydrophone system giving bearing and range estimations for use in open-water fish tracking is described together with a portable hand-held unit for simple location of tagged fish in rivers,(More)
Hypoxia tolerance is a plastic trait, and can vary between species. We compared hypoxia tolerance (hypoxic loss of equilibrium, LOE, and critical O2 tension, Pcrit) and traits that dictate O2 transport and metabolism in pumpkinseed (Lepomis gibbosus), bluegill (L. macrochirus), and the naturally occurring hybrid in different acclimation environments (wild(More)
We present pressure profiles of galaxy clusters determined from high-resolution Sunyaev–Zel’dovich (SZ) effect observations of 14 clusters, which span the redshift range of z 0.25 0.89 < < . The procedure simultaneously fits spherical cluster models to MUSTANG and Bolocam data. In this analysis, we adopt the generalized NFW parameterization of pressure(More)
The enhanced bending compliance function (eBCF) is a useful concept for estimation of static bending compliance/stiffness of a structure using measured frequency response functions (FRFs) from a structural system with free-free boundary conditions. The eBCF is estimated using FRF measurements involving impact testing that involve obtaining a six by six(More)
Milnesium swansoni sp. nov. is a new species of Eutardigrada described from the tree canopy in eastern Kansas, USA. This species within the order Apochela, family Milnesiidae, genus Milnesium is distinguished by its smooth cuticle, narrow buccal tube, four peribuccal lamellae, primary claws without accessory points, and a secondary claw configuration of(More)
The enhanced rotational compliance function (eRCF) is a useful concept for estimation of static torsional compliance/stiffness of a structure using measured frequency response functions (FRFs) from a structural system with free-free boundary conditions. The eRCF is estimated using FRF measurements involving impact testing in which a four by four (4x4) FRF(More)
We present high resolution (9′′) imaging of the Sunyaev–Zel’dovich Effect (SZE) toward two massive galaxy clusters, MACS J0647.7+7015 (z = 0.591) and MACS J1206.2–0847 (z = 0.439). We compare these 90 GHz measurements, taken with the Multiplexed Squid/TES Array at Ninety Gigahertz (MUSTANG ) receiver on the Green Bank Telescope, with generalized(More)
We present pressure profiles of galaxy clusters determined from high resolution Sunyaev-Zel’dovich (SZ) effect observations of fourteen clusters, which span the redshift range 0.25 < z < 0.89. The procedure simultaneously fits spherical cluster models to MUSTANG and Bolocam data. In this analysis, we adopt the generalized NFW parameterization of pressure(More)
