Adaptive optics observations of asteroid (216) Kleopatra
The large main-belt asteroid (216) Kleopatra has been for long suspected to be a binary object, mainly due to its large lightcurve amplitude. However, recent observations suggest that it is a single “bone-shaped” or bi-lobated body (Ostro et al. 2000; Tanga et al. 2001). We present results obtained from ground-based adaptive optics observations, and in agreement with the radar raw-observations,...
متن کاملHST/FGS Observations of the Asteroid (216) Kleopatra
Interferometric observations of asteroid (216) Kleopatra were performed in January 2000 using the Fine Guidance Sensors (FGS) aboard HST. The FGS data obtained clearly suggest that (216) Kleopatra is composed of two lobes in contact, in agreement with the radar data (Ostro et al. 2000, Science 288, 836–839), and provide more precise constraints on the absolute size of this peculiar object. c © ...

The aim of this study was to further characterize the expression and function of human CYP2B6 in a recently generated CYP2A13/ 2B6/2F1-transgenic (TG) mouse model, in which CYP2B6 is expressed selectively in the liver. The inducibility of CYP2B6 by phenobarbital (PB) and dexamethasone (DEX), known inducers of CYP2B6 in human liver, was examined in the TG mice, as well as in TG/Cyp2abfgs-null (o...

The human sense of shape and pattern recognition can discern subtle nuances among groups of visual cues that no computer system can reproduce faithfully. Yet when it comes to measuring and evaluating chromatograms, analysts put a great deal of faith into their computerized data-handling systems. During the course of one year, a practising chromatographer might look at 10 000 or more peaks. Afte...

Fuzzy C-means (FCM) is an unsupervised clustering technique that is often used for the unsuper-vised segmentation of multivariate images. In traditional FCM the clustering is based on spectral information only and the geometrical relationship between neighbouring pixels is not used in the clustering procedure. In this paper, the spatially guided FCM (SG-FCM) algorithm is presented which segment...
