Qilian Liang, an electrical engineering professor in the College of Engineering, has received grants from the Office of Naval Research and the National Science Foundation totaling more than $1.2 million.
The five-year, $797,500 ONR grant addresses a signal processing system that provides better information for radar even though it collects less data.
“When the Navy’s radar looks at a specific area, it takes into account everything in that area,” Dr. Liang says. “Much of that data isn’t needed for the system to come to a precise answer on what a radar system says is there. If you take in less data, it takes the system less time to make an informed decision.”
The three-year, $470,000 NSF grant is for developing a system in a cellphone that could automatically locate available space within a bandwidth, reducing or eliminating “dead spots” in coverage.
“In the wireless network industry, bandwidth is everything,” says Liang, who has been at UT Arlington since 2002. “The system I’m developing shows where the room is in a bandwidth.”

Physics Professor Zdzislaw Musielak has been awarded a three-year, $301,339 National Science Foundation grant to investigate Alfvén waves in the sun, a phenomenon vital to understanding Earth’s nearest star.
“The sun is the source of energy that sustains all life on Earth, but there is much that remains unknown about it,” says Dr. Musielak, a two-time winner of the international Humboldt Prize for his research into the sun and solar-type stars. “With this research, we hope to explore one of the great mysteries—what forces fuel the heat of the sun’s outer atmosphere and the basic physical processes for creating its magnetic influence on Earth and other planets.”
Alfvén waves are magnetic plasma waves named after Hannes Alfvén, who received a Nobel Prize in 1970. Their existence helps explain why the sun’s corona, or upper atmosphere, is hotter than the solar surface. Understanding Alfvén waves is also crucial to explaining the speed of solar winds, a stream of highly charge particles released into space by the sun.

Human-like robots with skin and clothes embedded with sensors that could help machines accurately perceive the environment and better assist human owners are at the heart of a new $1.35 million National Science Foundation project led by Dan Popa, associate professor of electrical engineering.
Dr. Popa, who leads the Next Gen Systems group within the College of Engineering, is the principal investigator of a collaborative effort to advance robots and robotic devices, improve prosthetics, and enable those devices to perform tasks that people can no longer do themselves.
The four-year project is part of the NSF’s National Robotics Initiative, which is aimed at accelerating the development and use of robots in the United States that work beside or cooperatively with people. The UT Arlington team’s grant was the largest among the initiative’s 37 awards this fall.
Co-principal investigators are Zeynep Celik-Butler, professor of electrical engineering and director of the Nanotechnology Research and Education Center; Donald Butler, professor of nanotechnology and electrical engineering; Frank Lewis, professor of electrical engineering and the Moncrief-O’Donnell Endowed Chair; and Nicoleta Bugnariu, associate professor of physical therapy and neuroscience at the University of North Texas Health Science Center in Fort Worth.
Researchers examining how the hormone jasmonate works to protect plants and promote their growth have revealed how a transcriptional repressor of the signaling pathway makes its way into the nucleus of the plant cell.
They hope the recently published discovery eventually will help farmers experience better crop yields with less use of potentially harmful chemicals.
“This is a small piece of a bigger picture, but it is a very important piece,” says Maeli Melotto, an assistant professor of biology.
Dr. Melotto co-authored a paper that advances current understanding of plant defense mechanisms with Sheng Yang He and his team at Michigan State University’s Department of Energy Plant Research Laboratory. The paper “Transcription factor-dependent nuclear import of transcriptional repressor in jasmonate hormone signaling” was published in the Proceedings of the National Academy of Sciences.

Khosrow Behbehani, chair of the Department of Biogengineering, has been named a fellow of the Institute of Electrical and Electronics Engineers.
Dr. Behbehani, also a bioengineering professor, was honored for his contributions to the development of respiratory therapy devices in chronic pulmonary diseases. He becomes the seventh UT Arlington faculty member to be elevated to IEEE fellow.
The majority of Behbehani’s work has focused on inventing devices and methods for diagnosis and treatment of sleep apnea. In the 1990s, he and his team developed a device for treating sleep apnea patients, which was commercialized and used for treatment on several hundred people. Behbehani and his colleagues hold nine U.S. patents on devices and methods related to sleep apnea diagnosis and treatment.
“Behbehani’s work on sleep apnea is so important because the malady affects so many people in various ways,” says Jean-Pierre Bardet, dean of the College of Engineering. “And Behbehani’s sleep apnea research could lead to all kinds of different applications from here. What’s important is that better detection can lead to early and effective treatment.”

A chemistry team researching ruthenium compounds as possible anti-cancer drugs has discovered a way to make their complexes more effective against cancer cells and less toxic to healthy cells in lab tests.
Chemistry Professor Fred MacDonnell presented the team’s work this month at the 24th International Symposium on Chiral Discrimination in Fort Worth.
Platinum-based drugs are now the first line of treatment for many cancer patients. Scientists working with similar elements, such as ruthenium, hope to develop effective, less toxic alternative chemotherapy drugs.
Dr. MacDonnell noted that these ruthenium compounds work well against tumor cells under hypoxic, or low-oxygen, conditions. Such compounds could be useful to target the subpopulation of hypoxic cancer cells in solid tumors, as these cells are often the most resistant to drug treatment.
MacDonnell’s co-presenters at the conference were Abhishek Yadav, Thamara Jaranatne, and Arthi Krishnan, all past graduate students at UT Arlington.

Two engineering researchers have been awarded a three-year, $640,000 NASA National Research Award to study novel injector designs to support combustion at hypersonic speeds, work aimed at reducing air travel times and making space access affordable.
Luca Maddalena and Luca Massa, both assistant professors in the Department of Mechanical and Aerospace Engineering, are the only collegiate researchers in the country to garner the NASA hypersonic award.
“We’re honored to be the only U.S. grant winners to study this very important topic,” Dr. Maddalena says. “This study on the effectiveness of new fuel injection schemes might lead to enabling affordable access to space for large hypersonic vehicles.”
Hypersonic speed is that which reaches Mach 5, or 3,500 miles per hour and more. Hypersonic technology differs from rocket technology in that hypersonic engines pull oxygen from the surrounding air. Rocket propulsion engines carry their oxygen source on board, which limits the payload of what the aircraft can carry.
