Period three actions on lens spaces
We show that a free period three action on a lens space is standard, i.e. the
quotient is homeomorphic to a lens space. This is an extension of the result
for period three actions on the three-sphere, arXiv:math.GT/0204077, by the
author and J. Hyam Rubinstein.Comment: 67 pages, 54 picture
When is a trigonometric polynomial not a trigonometric polynomial?
As an application of B\'ezout's theorem from algebraic geometry, we show that
the standard notion of a trigonometric polynomial does not agree with a more
naive, but reasonable notion of trigonometric polynomial.Comment: 3 page

Digital Systems Teaching and Research (DSTR) Robot: A Flexible Platform for Education and Applied Research
The DSTR (pronounced “Disaster”) robot has a strong history of being adaptable to different user’s needs, and there are many opportunities ahead that indicate that the sky, quite literally, is not the limit for this robust platform. This paper provides a historical perspective on the development of the DSTR robot as a collaborative design developed by the Mobile Integrated Solutions Laboratory (MISL) at Texas A&M University and ASEP 4X4 Inc. Texas Instruments has been a major partner in the integration of the control electronics, and Texas Space Technology Applications and Research (T STAR) LLC has played a significant role in the propagation of the DSTR robot as an adaptable applied research/education/STEM outreach platform. The paper will present examples of the strong industry-academic relationships that allow the DSTR robot to be utilized in a multitude of experiential learning environments. In addition to a number of STEM outreach activities, the DSTR robots are being used in the Introduction to Engineering course at Blinn College and in the Freshman Engineering curriculum at Texas A&M University. DSTRs have also been selected by NASA scientists as a low-cost lunar sample collector. The paper will also discuss the newly developed DSTR-E (DSTR Engineering) unit which requires students to perform several engineering tasks during the build process. The paper will also include the lessons learned from initial design through its transfer to the private sector for commercialization and future plans.Cockrell School of Engineerin

Black Holes and Galactic Density Cusps Spherically Symmetric Anisotropic Cusps
Aims: In this paper we study density cusps that may contain central black
holes. The actual co-eval self-similar growth would not distinguish between the
central object and the surroundings. Methods: To study the environment of a
growing black hole we seek descriptions of steady `cusps' that may contain a
black hole and that retain at least a memory of self-similarity. We refer to
the environment in brief as the `bulge' and on smaller scales, the `halo'.
Results: We find simple descriptions of the simulations of collisionless matter
by comparing predicted densities, velocity dispersions and distribution
functions with the simulations. In some cases central point masses may be
included by iteration. We emphasize that the co-eval self-similar growth allows
an explanation of the black hole bulge mass correlation between approximately
similar collisionless systems. Conclusions: We have derived our results from
first principles assuming adiabatic self-similarity and either self-similar
virialisation or normal steady virialisation. We conclude that distribution
functions that retain a memory of self-similar evolution provide an
understanding of collisionless systems. The implied energy relaxation of the
collisionless matter is due to the time dependence. Phase mixing relaxation may
be enhanced by clump-clump interactions.Comment: 9 pp, 3 figs, accepted by A\&
How to Improve an Existing Training Program
Increasing the effectiveness of any training program is an ongoing undertaking that may require refinement year after year. The purpose of this MDS Capstone Project is to increase the effectiveness of our agent community, as well as our internal staff, when it comes to identifying missing information during the implementation process of a new group that is being on-boarded for health insurance. Missing information, errors, and inaccurate information can lead to delays when on-boarding a new group. These delays may also lead to increase workloads, increased cost through employee’s having to work overtime, and upset customers. Restructuring this training program, in order to create a new and innovative approach, involved input from many sources that helped to produce a flexible platform which can be augmented to suit the ever changing health insurance landscape.
Our company will have a new training program that can be used for years to come. This training program is scalable to fit almost any audience, and can be adjusted easily for changes that impact the health insurance landscape year after year. Implementing a streamlined training will allow our organization to cut down on the time it takes to on-board a new group, while at the same time saving valuable resources and expense long the way

Trafficking in women: International sex services
This research looks to identify precursors to women becoming involved in trafficking for prostitution and/or sexual services in the United States. The failure to find patterns or trends regarding why women are trafficked or what types of women are trafficked most often, helps dispel some myths regarding the stereotypical victim of trafficking
