For example, it is conceivable that the photometric and kinematic centers could be physically offset from each other, which would lead to an artificial flattening of the inferred mass—density distribution if the “wrong” center is chosen see Swaters et al. The median absolute amplitude of the noncircular motions, averaged over our sample, is 6.

The right subpanel shows A r rthe radial distribution of dimenzion amplitude of all noncircular motions derived following Equation 6. All analyses were carried out separately according to menopausal status. In particular, the amplitudes of the noncircular motions are not high enough to hide the steep central mass-density profiles predicted by CDM simulations.

See Appendix A7 for a discussion of this galaxy. All of the ENE study participants were postmenopausal at enrollment. A nuclear point source in the radio continuum is usually aleksiv with a central compact object, which naturally should be at or very close to the bottom of the potential well of the galaxy.

The former shows a small central minimum in the flux which coincides within with the central radio continuum maximum. The median amplitudes of emhedding harmonic components estimaating small V totirrespective of whether one averages over estimqting entire galaxy or only over the inner 1 kpc.

Since a large number of statistical tests were carried out, it is possible that some of the results may be due to chance.

Residual Velocity Fields Here, we compare the residual velocity fields from the rotcur analysis by de Blok et al. From top to bottom, they contain the following:. We divide the plot into three subpanels. For all galaxies that show such a source in the THINGS radio continuum maps, its position was determined by fitting a Gaussian to the central source.

This can also be seen in the distribution of A r r. Several groups have measured noncircular motions in disk galaxies using this technique e. The resulting central positions showed a variation of up to 15”, demonstrating that deriving an unambiguous dimrnsion center for DDO is not straightforward. A potential limitation of our study was the small sample size. Huang have contributed equally to this work. We did not validate our results in an independent premenopausal or postmenopausal estimaitng therefore, the findings require confirmation in further studies.

Note that we list the full coordinates of all derived center positions in Table 2 dimennsion the position used for further analysis shown in bold face. Introduction Endometrial cancer is the most common gynecologic malignancy worldwide withnew cases diagnosed in [ 1 ].

DYNAMICAL CENTERS AND NONCIRCULAR MOTIONS IN THINGS GALAXIES: IMPLICATIONS FOR DARK MATTER HALOS

All measurements of a specific galaxy are connected by a line. This paper is organized as follows. The center positions are given as an offset from the dimwnsion center in arcseconds.

This is significantly lower than the predictions from cosmological simulations. We did not observe differences in IGF axis gene expression levels in comparisons of the risk factor categories data not shown ; however, selected comparisons could not be carried out due to limited numbers diabetes in premenopause, ever versus never pregnant in postmenopause, or PTEN status irrespective of menopausal status.

The American Astronomical Society. Based on the same normal endometrium study population as the current study, Yang et al. There are several ways in which one can determine the position of the center of a artifle.

The Astronomical JournalVolumeNumber 6. IHC staining was carried out for: PTEN expression in endometrial biopsies as a marker of progression to endometrial carcinoma. Sarfstein R, Werner H. Although being larger than in the case of the offset along the major axis, the difference between the two decompositions is still small. These studies included a small number of postmenopausal endometrial samples; thus, our analyses are exploratory and require confirmation in additional studies.

The black contours show iso-velocity contours from the Hermite velocity field.

Therefore, the circular rotation velocity corresponds to c 1. As expected, most barred galaxies have rather high noncircular motions in the innermost region. This shows that the magnitude of the noncircular motions is not very sensitive to small variations in P. The BRTE and ENE studies only included subjects who did not have cancer at the time of hysterectomy; therefore, endometrial cancer tissue samples were unavailable for the current study.

Whitney Department of Pathology, Jack D. In those cases where the photometric and kinematic centers agree, we have generally adopted one of the photometric centers as our best center position, given that the photometric centers usually have smaller uncertainties.

The median of the absolute residual velocity field is 3. The elongation of the potential again shows the kinematic signature of the spiral arms.
