Integrated Circuit Runs Again
Integrated Circuit, the Department's seven person running team again ran in this year's Seneca 7 Relay Race on April 28. The race is 77.7 miles around around Seneca Lake. Each runner completes three of the 21 different legs of the course which starts and ends in Geneva. The team finished in 10 hours, 41 minutes and 57 seconds (8:15 pace) which was good enough for 54th place out of 154 teams. While other teams from the Colleges competed, ours was the only department at HWS to field an entire team. Running for Integrated Circuit this year were:
Top: Nicholas MacDonald (H'12), Trevor Gionet, (H '12), Professors Jon Forde, Stina Bridgeman, and Carol Critchlow. Bottom: Professor Kevin Mitchell and Abigael Blumenthal (WS '14). All of the faculty competed last year as well.

Gionet Receives Fulbright Scholarship
Trevor Gionet (H'12) has been awarded a Fulbright English Teaching Assistantship
for study in Vietnam. In addition to teaching English, Trevor will take Vietnamese language lessons
focused on mathematics. With this, he hopes to be able to teach
math bilingually.
The Fulbright Program was established by the U.S. Congress in 1946. The purpose of the Fulbright Program worldwide is "to increase mutual understanding between the people of the United States and the people of other countries by means of educational and cultural exchange." The U.S. State Department's Bureau of Educational & Cultural Affairs (ECA) is the principal administrator of the Fulbright Program. Bi-national commissions, composed equally of U.S. and partner-country citizens, coordinate Fulbright Programs in fifty-one of the 140 participating countries.

Yaoxin Liu Honors Project
Yaoxin Liu, H'12, has completed an Honors project titled,
"A Mathematical Model: Hepatitis B and Hepatitis D Co-infection."
An Honors project is a year-long endeavor culminating in a long Honors thesis and an oral examination by a committee of three examiners.
Here is a description of his project: "In this honors project, mathematical models are developed to describe the
interaction between human liver cells, hepatitis B virus (HBV) and hepatitis
delta virus (HDV). HDV is a dependent virus that can only infect patients who
are also HBV-infected, and it causes more severe damage to liver cells than HBV
alone. This project is an extension of previous research, which focused on
analyzing the impact of immune exhaustion on HBV and HDV infections. Shifting
the emphasis to the dynamics of the infections, this honors project will shed
light on what causes the severe damage to liver cells. Mathematical models of
the system are built from a simpler model of a single infection and used to
explore the possible outcomes of HBV and HDV co-infection. Computer simulations
are also created to support analytical results. Manipulation the magnitude of
different parameters has helped in understanding how different host and viral
factors affect the severity of disease." Yaoxin's advisor on this project was Professor Jon Forde.

Marcela Melara Honors Project
Marcela Melara, WS'12, has completed an Honors project
titled, "ELARA: Environmental Liaison and Automated Recycling Assistant." An Honors project is a year-long endeavor culminating
in a long Honors thesis and an oral examination by a committee of
three examiners. Here is a description of Marcela's project:
"One environmental issue we face today is dealing with the large amounts of
landfill garbage. While many efforts are already being made to increase recycling,
many people still have trouble identifying and sorting recyclable materials.
In order to improve this situation, I designed and built ELARA. This is a new
system that facilitates recycling and waste sorting by helping people identify
the items which are recyclable and those which are not. The most immediately
noticeable aspect of ELARA is a networked kiosk to help users sort their waste
correctly. The kiosk is the front end of a larger system of hardware and software." Marcela's advisor for this project was Professor John Vaughn.

Shaun Viguerie Honors Project
Shaun Viguerie H'12 has completed an Honors project
entitled "ISTAT: Online Interface for Hypothesis Testing."
An Honors project is a year-long endeavor that culminates with
a long Honors thesis and an oral examination by a committee of
three examiners. Here is a description of his project:
"This honors project involved the creation of an online statistical software
application (called ISTAT) for hypothesis testing. The package has a user-friendly
interface, and is able to work with data from a variety of different sources.
Designed for student use, it supports hypothesis tests commonly covered in
introductory statistics courses. The core functionality of the application lies
in JavaScript libraries, making it easily extendable. By utilizing many modern
web technologies, the project demonstrates the improving capabilities of the web
as a platform for complex applications." Shaun's advisor for this
project was Professor David Eck.

News from Max Beckett
Max Beckett '11 writes as he nears the halfway point in a
Master's degree program in computer science at Northeastern
University. Max, who was a double major in mathematics and
computer science, is working with a research group known as
the ReConfigurable Lab (RCL). He has been spending his time
there working on GPGPU (General-Purpose computing on Graphics
Processing Units), an attempt to harness the immense computing
power of modern graphics cards for other purposes than graphics.
Max first started work on this field for an independent study at HWS.
This summer, Max will have a internship with Mathworks, the company
that makes MatLab, doing more
work with GPUs for their Parallel Computing Toolbox.

Movie Night: The Proof
For over 350 years, some of the greatest minds of science struggled to prove what was known as Fermat's Last Theorem -- the idea that a certain simple equation had no solutions. Now hear from the man who spent seven years of his life cracking the problem, read the intriguing story of an 18th century woman mathematician who hid her identity in order to work on Fermat's Last Theorem, and demonstrate that a related equation, the Pythagorean Theorem, is true.
Andrew Wiles devoted much of his career to proving Fermat's Last Theorem, a challenge that perplexed the best minds in mathematics for 300 years. In 1993, he made front-page headlines when he announced a proof of the problem, but this was not the end of the story; an error in his calculation jeopardized his life's work. In this interview, Wiles recounts how he came to terms with the mistake, and eventually went on to achieve his life's ambition.
The department will show the movie on Thursday, December 1st at 7:30pm in Albright Auditorium. Refreshments will be provided. Bring your friends!

If Copernicus and Kepler Had Computers: An Introduction to Model-Building and Computational Science
On Thursday, November 17th at 5:00pm, Dr. Charles Van Loan, a SIAM Visiting Lecturer, will give a talk in Napier 201 that connects mathematics and computer science. If you watch Mars against the backdrop of the fixed stars, then night after night you'll see rather steady progress across the zodiac. But every so often, the planet appears to "back-up" before continuing on its forward trek. This periodic, retrograde motion wreaks havoc with a model of the solar system that places each planet on a steadily rotating circle with Earth at the center. Ptolemy did a pretty good job patching up the model by placing each planet on a small rotating circle whose center is on the rim of a larger rotating circle. The path traced out is called an epicycle and it offers some explanation for Mars' orbital wanderings. The epicycle model lasted for centuries until Copernicus set the record straight by suggesting that the Earth revolved around the sun along with the other planets. But would he have been so bold a scientist if he had access to 2011 computers? Or would he have just mouse-clicked his way into fame, developing a simulation package that supported further tinkering with the Ptolemaic model? (Refreshments will be served.)

A Mathematical Model of T Cell Exhaustion Caused by HBV/HDV
On Wednesday, November 9th at 4:30pm, Hobart Mathematics Major Yaoxin Liu '12 will discuss his summer research project in Napier 201. In patients with chronic hepatitis B infection, the immune system becomes exhausted, losing its effectiveness over time. Co-infection with another virus, Hepatitis Delta, reduces the amount of HBV in the blood, and so may relieve the exhaustion. During the Summer Research Program last summer, Yixiao Sha, Yaoxin Liu and Prof. Jonathan Forde developed an ordinary differential equation model of the interactions of these two viruses and the immune system to study the effect of a second infection on immune exhaustion. Sha, Liu and Forde started by studying the four dimensional model with only HBV infection, and then added the second virus, HDV. They also analyzed various steady states and their stability for both systems. All the stability conditions are found for the four dimensional system with only HBV infection. For the five dimensional system with HDV, numerical simulations show the existence of positive steady states representing chronic coinfection. The model suggests that co-infection does not reduce the exhaustion level, but increases damage due to general inflammation. (Refreshments will be served beforehand.)
