A critical and annotated catalogue of the ninety-six type specimens of Chrysididae (Hymenoptera), belonging to sixty-seven species, housed in the insect collection of Maximilian Spinola is given. The neotypes of six species are designated: Chrysisbicolor Lepeletier, 1806; Chrysiscomparata Lepeletier, 1806; Chrysisdives Dahlbom, 1854; Chrysispumila Klug, 1845; Chrysissuccincta Linnaeus, 1767; He...

The time interval between successive bursts from SGR 1806-20 and the intensity of these bursts are both consistent with lognormal distributions. Monte Carlo simulations of lognormal burst models with a range of distribution parameters have been investigated. The main conclusions are that while most sources like SGR 1806-20 should be detected in a time interval of 25 years, sources with means ab...

The interpretation of Linnaeus' name Sphex semiaurata Linnaeus, 1761 has been controversial. After type examinations, we conclude that it is identical with the common Cleptes pallipes Lepeletier, 1806 and thus re-establish the old synonymy: Cleptes semiauratus (Linnaeus, 1761) (=Cleptes pallipes Lepeletier, 1806, syn. reinst.). We have been unable to find an available name for the species with ...

The Soft Gamma Repeater 1806-20 produced patterns of bursts during its 1983 outburst that indicate multiple independent energy accumulation sites, each driven by a continuous power source, with sudden, incomplete releases of the accumulated energy. The strengths of the power sources and their durations of activity vary over several orders of magnitude. Subject headings: gamma-rays:bursts — star...

A striking proportion of human cleavage-stage embryos exhibit chromosome instability (CIN). Notably, until now, no experimental model has been described to determine the origin and mechanisms of complex chromosomal rearrangements. Here, we examined mouse embryos deficient for the chromatin remodeling protein ATRX to determine the cellular mechanisms activated in response to CIN. We demonstrate ...

We present observations of the Soft γ-ray Repeater SGR 1806−20 taken with the Chandra X-ray Observatory. We identify the X-ray counterpart of SGR 1806−20 based on detection of 7.5-s pulsations. Using three unrelated X-ray sources (and USNO stars) as position references, we are able to determine that the SGR is at α2000 = 18 0839. 32 and δ2000 = −2

We discuss observations of the soft gamma repeater SGR 1806–20 during the RXTE Target of Opportunity observations made in November 1996. During the ∼ 50 ksec RXTE observation, HEXTE (15− 250 keV) detected 17 bursts from the source, with fluxes ranging from 3× 10 to 2.2× 10 ergs cm s (20− 100 keV). We obtained spectra for the brighter HEXTE by fitting thermal bremsstrahlung and power law functio...

We present K -band (2.12 μm) imaging observations of the SGR 1806–20 field taken during its very active phase in mid 2004, which reveal brightening of sources within the Chandra X-ray error circle when compared with earlier images obtained in 2002. One source brightened by more than a factor of 2, and so we consider this to be the probable infrared counterpart for SGR 1806–20. The other two sou...
