Dora Musielak, an adjunct professor of physics and aerospace engineering, has taken on the mystery of how a woman growing up in late-18th century France came out of nowhere to make a name for herself with the world’s most renowned mathematicians.
The Mathematical Association of America recently republished Sophie’s Diary: A Mathematical Novel. In the 279-page book, Dr. Musielak uses fiction to take up where records about mathematician Sophie Germain leave off.
The author follows Germain from ages 13 to 17, during the years 1789 to 1793. She hopes the novel inspires mathematicians, especially young women, and informs the world about Germain’s contributions.

Researchers patent SIDS detection device
UT Arlington researchers have obtained a patent for a device aimed at saving babies’ lives through improved and rapid detection of Sudden Infant Death Syndrome.
Electrical Engineering Professor J.-C. Chiao, doctoral candidate Hung Cao, and Heather Beardsley, a research engineer at TMAC (Texas Manufacturing Assistance Center), have developed a sensitive wireless sensor system that can detect carbon dioxide exhaled by babies as they sleep. More importantly, the sensors know when infants are not expelling carbon dioxide—quickly enough to allow intervention.
“This has the chance to save lives,” says Dr. Chiao, who holds the Janet and Mike Greene and Jenkins Garrett professorships in the College of Engineering. “Our system is more accurate than current systems. Our system reduces false alarms that desensitize parents or caregivers.”
SIDS typically occurs in infants younger than a year old while the child is sleeping. Cases are classified as SIDS when there is no other explainable cause of death.

A group of infants and mothers tested at UT Arlington have given researchers another reason to extol the unique properties of breast milk.
A team led by Sandy Dasgupta, Jenkins Garrett Professor of Chemistry and Biochemistry, has found evidence that breast-fed babies can metabolize the environmental contaminant perchlorate, decreasing their risks of detrimental developmental effects from exposure.
The research suggests a link between this characteristic and bifidobacteria, bacteria that is plentiful in the digestive systems of breast-fed babies.
The team’s work with 18 pairs of infants and mothers is detailed in the article “Breast-fed Infants Metabolize Perchlorate,” which was recently accepted for publication by the American Chemical Society journal Environmental Science & Technology.
“Both Centers for Disease Control researchers and our lab have previously observed that there is a higher concentration of perchlorate in breast milk versus formula. Although the merits of breastfeeding far outweigh any risk posed by this, it has caused some mothers concern.” Dr. Dasgupta says. “Our results suggest that nature has already devised a way to at least partly take care of it.”

Nursing Professor Judy LeFlore has earned national recognition from the 2012 Computerworld Honors Laureate program for her work using 3D gaming technology to teach students about in-hospital pediatric care.
Dr. LeFlore’s project “Can Game Play Teach Student Nurses How to Save Lives?” explored whether a 3D video game could teach nursing students how to respond to patients in a clinical setting. She and Assistant Professor Mindi Anderson worked with Marjorie Zielke, assistant professor of arts and technology at UT Dallas, to develop a game scenario called “iNursingRN: Respiratory Distress.”
The work was backed by $250,000 in funding from the UT System’s Transforming Undergraduate Education grant program. Dr. Zielke and LeFlore will receive the award in June in Washington, D.C.

A UT Arlington multidisciplinary team has received a $360,000 grant from the National Science Foundation to build artificial nanopores made of silicon that can detect “bad molecules” as a very early indication of cancer and other diseases.
Samir Iqbal, an assistant professor of electrical engineering who focuses on nanotechnology, is leading the project. He works with Sandy Dasgupta, the Jenkins Garrett Professor of Chemistry and Biochemistry, and Richard Timmons, a Distinguished Professor of Chemistry.
Nanopores are tiny openings—about 1,000 times smaller than a human pore on the skin or a human hair—made in very thin silicon chips. The silicon chips are the same material in computer processors and memories.
Dr. Iqbal’s team will run human blood-derived samples through these artificially created nanopores in a silicon chip and record how the composition may change as a function of disease.

UT Arlington industrial engineers have patented an innovative method that can obtain optimal decisions for a broad class of real-world problems not previously solvable.
Bill Corley and Jay Rosenberger, professor and associate professor in the Department of Industrial and Manufacturing Systems Engineering, recently were issued a patent titled “System, Method, and Apparatus for Allocating Resources by Constraint Selection.”
Linear programming is a mathematical description of a vast number of decision problems occurring throughout the business and scientific worlds. Solving these problems allows an organization to maximize profit, minimize costs, or allocate resources.
“Linear programming is the most widely used computational model in the business and scientific worlds,” Dr. Corley says. “It will now become much more important. That’s the bottom line. We drastically improved over 60 years of research for computing with this ubiquitous decision model.”

A team of University of Texas at Arlington researchers have developed a method that uses magnetic carbon nanoparticles to target and destroy cancer cells through laser therapy—a treatment they believe could be effective in cases of skin and other cancers without damaging surrounding healthy cells.
A paper about the work by Ali R. Koymen, professor of physics, and Samarendra Mohanty, assistant professor of physics, was published in January’s edition of the Journal of Biomedical Optics.
Ling Gu and Vijayalakshmi Vardarajan, two post-doctoral researchers in Dr. Mohanty’s lab, were coauthors on the paper “Magnetic-field-assisted photothermal therapy of cancer cells using Fe-doped carbon nanoparticles.”
Mohanty says the carbon nanoparticles can be coated to make them attach to cancer cells once they are positioned in an organ by the magnetic field. The magnetic carbon nanoparticles also are fluorescent, so they can be used to enhance contrast of optical imaging of tumors along with that of MRI.

Qilian Liang, professor of electrical engineering, has received a $300,000 National Science Foundation grant to determine how much closer technology can push toward the upper boundary of a smart grid’s threshold.
Dr. Liang joined UT Arlington in 2002 and is working to marry electrical grid infrastructure with information technologies to transmit and distribute power closer to that threshold. The goal of the project is to determine the threshold and to figure out the roadmap toward that threshold.
One study conducted by the U.S. Department of Energy concludes that internal modernization could save between $46 billion and $117 billion in 20 years. A smart grid is a digitally enabled electrical grid that collects information about usage and demand then acts to improve the efficiency, reliability, and sustainability of electricity services.

The College of Nursing will use a $419,000 federal grant to bolster recruitment of minorities to its nursing Ph.D. program with hopes of addressing cultural disparities in health research and patient care.
The grant—a three-year award from the U.S. Department of Health and Human Services—will provide funds to recruit candidates from historically underrepresented groups and ensure the success of students through mentoring, professional socialization, and enhanced academic advising. Administrators believe their efforts will result in more students and graduates doing research related to disparities and provide more Ph.D.-prepared nurses to increase the number of minority faculty in nursing programs.
“The shortage of Ph.D.-prepared nurses is especially acute among minority nurses,” says Jennifer Gray, associate dean of the College of Nursing and principal investigator on the new grant. “As we have more and more minority patients seeking health care, we need minority health care providers who better understand their culture and could possibly be more effective.”

A group of UT Arlington astrophysicists expanded the discussion about a newly discovered planet orbiting two stars by presenting a study suggesting where an Earth-type planet could exist in the system.
The Kepler-16 System made headlines in September when researchers at NASA’s Kepler space telescope mission revealed the discovery of Kepler-16b, a cold, gaseous planet that orbits two stars like Star Wars’ fictional Tatooine.
The UT Arlington team, using data from the Kepler and previous research, has concluded that an Earth-type planet could exist in the system’s “habitable zone” as an exomoon orbiting Kepler-16b.
Billy Quarles, a doctoral student in the College of Science, presented the findings at the annual meeting of the American Astronomical Society this week in Austin. Co-authors are physics Professor Zdzislaw Musielak and Associate Professor Manfred Cuntz.

UT Arlington bioengineering researchers have designed an innovative, ultrasonic sensor system that can accurately detect whether a person suffers from sleep apnea without the inconvenience or cost associated with an overnight stay in a sleep center.
Researchers have applied for a provisional patent and are identifying private partners to market the device. UT Arlington has formed an alliance with Sleep Consultants Inc. in Fort Worth to conduct studies related to the research.
The new detection system promises a speedier path to diagnosis and eventual relief, says Khosrow Behbehani, professor and chair of the Department of Bioengineering, adding that conventional diagnostic testing can cost as much as $2,000 per patient per test. “For some, the cost is such a barrier that they may opt to continue to suffer rather than to be diagnosed.”
