The Tully-Fisher relations of early-type spiral and S0 galaxies
- Michael J. Williams, M. Bureau, Michele Cappellari University of Oxford, Eso
- Physics
- 23 July 2010
We demonstrate that the comparison of Tully-Fisher relations (TFRs) derived from global H I line widths to TFRs derived from the circular velocity profiles of dynamical models (or stellar kinematic… Expand
Drosophila Insulin-Producing Cells Are Differentially Modulated by Serotonin and Octopamine Receptors and Affect Social Behavior
- J. Luo, O. Lushchak, Philip Goergen, Michael J. Williams, D. Nässel
- Biology, Medicine
- PloS one
- 12 June 2014
A set of 14 insulin-producing cells (IPCs) in the Drosophila brain produces three insulin-like peptides (DILP2, 3 and 5). Activity in IPCs and release of DILPs is nutrient dependent and controlled by… Expand
Central rotations of Milky Way globular clusters
- M. Fabricius, E. Noyola, +6 authors Michael J. Williams
- Physics
- 7 May 2014
Most Milky Way globular clusters (GCs) exhibit measurable flattening, even if on a very low level. Both cluster rotation and tidal fields are thought to cause this flattening. Nevertheless, rotation… Expand
Kinematic constraints on the stellar and dark matter content of spiral and S0 galaxies
- Michael J. Williams, M. Bureau, M. Cappellari
- Physics
- 3 September 2009
We present mass models of a sample of 14 spiral and 14 SO galaxies that constrain their stellar and dark matter content. For each galaxy, we derive the stellar mass distribution from near-infrared… Expand
The Drosophila cell adhesion molecule Neuroglian regulates Lissencephaly-1 localisation in circulating immunosurveillance cells
- Michael J. Williams
- Biology, Medicine
- BMC Immunology
- 25 March 2009
BackgroundWhen the parasitoid wasp Leptopilina boulardi lays its eggs in Drosophila larvae phagocytic cells called plasmatocytes and specialized cells known as lamellocytes encapsulate the egg. This… Expand
Measuring Dark Matter Profiles Non-Parametrically in Dwarf Spheroidals: An Application to Draco
- J. Jardel, K. Gebhardt, M. Fabricius, N. Drory, Michael J. Williams
- Physics
- 22 November 2012
We introduce a novel implementation of orbit-based (or Schwarzschild) modeling that allows dark matter density profiles to be calculated non-parametrically in nearby galaxies. Our models require no… Expand
What model organisms and interactomics can reveal about the genetics of human obesity
- Michael J. Williams, M. S. Almén, R. Fredriksson, H. Schiöth
- Biology, Medicine
- Cellular and Molecular Life Sciences
- 23 May 2012
Genome-wide association studies have identified a number of genes associated with human body weight. While some of these genes are large fields within obesity research, such as MC4R, POMC, FTO and… Expand
The Rho-Family GTPase Rac1 Regulates Integrin Localization in Drosophila Immunosurveillance Cells
- M. J. Xavier, Michael J. Williams
- Biology, Medicine
- PloS one
- 16 May 2011
Background When the parasitoid wasp Leptopilina boulardi lays an egg in a Drosophila larva, phagocytic cells called plasmatocytes and specialized cells known as lamellocytes encapsulate the egg. The… Expand
Miocene Vertebrate Fossils Recovered from the Pascagoula Formation in Southeastern Louisiana
- J. A. Schiebout, J. Wrenn, +5 authors B. Ellwood
- Geology
- 2006
Abstract The first significant vertebrate fossil site in the Pascagoula Formation was discovered at a location in the Tunica Hills in southeastern Louisiana during June, 2005. A mastodon palate with… Expand

Miocene Lower Vertebrates from Fort Polk, LA: a Preliminary Report
- Michael J. Williams, J. A. Schiebout
- Geology
- 2003
ABSTRACT Miocene vertebrates were first recovered from Fleming Formation outcrops on Fort Polk in western Louisiana in 1993, and most Fort Polk fossils are most closely comparable to animals of the… Expand
