Optimizing ?0 information from the Jason-2 altimeter
No full textA radar altimeter's normalized backscatter, ?0, is used in many oceanographic applications, to infer values of wind speed, wind stress, rain rate and the presence of biogenic slicks. The waveform retracker used to estimate the key geophysical variables for the altimeters on the Jason-1 and Jason-2 satellites shows increased small-scale variability since the problem is ill-conditioned. A simple empirical adjustment to ?0 improves the separability between various parameters and also improves the along-track profiles of ?0. This leads to i) more realistic wind fields, ii) better discrimination of rain events, and iii) improved comparison between the Jason-1 and Jason-2 altimeters during their tandem mission
The Laccate Ganoderma of the Southeastern United States: A Cosmopolitan and Important Genus of Wood Decay Fungi
No full textGanoderma Karst. is a large and diverse genus of wood decay fungi that can rot the roots and/or lower trunk of many tree species. There are several laccate (varnished or polished) Ganoderma species that are found in the southeastern United States and this six-page fact sheet provides an overview of the different species.

Synthesis of ene-1,1-diamines and pyrrolo [1,2-a] imidazolediones by 4,5-dihydroimidazole N-oxide cycloaddition and isoxazoline ring opening
No full textDihydroimidazole N-oxides 1 undergo 1,3-dipolar cycloaddition with alkyne dipolarophiles and the cycloadducts suffer isoxazoline N-O bond cleavage to afford ene-1,1-diamines, with subsequent cyclisation to pyrrolo[1,2-a]imidazole-5,6-diones if possible
Sphecodes dichrous Smith 1853

Doubleday (NHM). = Sphecodes knetschi Cockerell 1898 (New synonymy) Syntype. ♀ ♂ USA, Illinois, Terra Cotta, 25 Aug. 1897, 5 Sep. 1897, goldenrod, R. Knetsch (NMNH). County records: Clinton, Ingham, Jackson, Livingston, Muskegon, Washtenaw. Notes. Mitchell (1960) records this species under both names. Although the synonymy, first recognized by Mike Arduser, has been applied implicitly, it has not been published formally.Published as part of Gibbs, Jason, Ascher, John S., Rightmyer, Molly G. & Isaacs, Rufus, 2017, The bees of Michigan (Hymenoptera: Apoidea: Anthophila), with notes on distribution, taxonomy, pollination, and natural history, pp. 1-160 in Zootaxa 4352 (1) on page 95, DOI: 10.11646/zootaxa.4352.1.1, http://zenodo.org/record/106385
GPI Spectra of HR 8799 c, d, and e from 1.5 To 2.4 μm with KLIP Forward Modeling
No full textWe explore KLIP forward modeling spectral extraction on Gemini Planet Imager coronagraphic data of HR 8799, using PyKLIP, and show algorithm stability with varying KLIP parameters. We report new and re-reduced spectrophotometry of HR 8799 c, d, and e in the H and K bands. We discuss a strategy for choosing optimal KLIP PSF subtraction parameters by injecting simulated sources and recovering them over a range of parameters. The K1/K2 spectra for HR 8799 c and d are similar to previously published results from the same data set. We also present a K-band spectrum of HR 8799 e for the first time and show that our H-band spectra agree well with previously published spectra from the VLT/SPHERE instrument. We show that HR 8799 c and d show significant differences in their H and K spectra, but do not find any conclusive differences between d and e, nor between c and e, likely due to large error bars in the recovered spectrum of e. Compared to M-, L-, and T-type field brown dwarfs, all three planets are most consistent with mid- and late-L spectral types. All objects are consistent with low gravity, but a lack of standard spectra for low gravity limit the ability to fit the best spectral type. We discuss how dedicated modeling efforts can better fit HR 8799 planets\u27 near-IR flux, as well as how differences between the properties of these planets can be further explored
