- To eat or not to eat
UCLA researchers have developed a disposable biosensor that may help doctors determine which patients should be fed following surgery
Kim Irwin | August 12, 2014
A disposable plastic listening device that attaches to the abdomen may help doctors definitively determine which post-operative patients should be fed and which should not, an invention that may improve outcomes, decrease healthcare costs and shorten hospital stays, according to a UCLA study.
Some patients who undergo surgery develop a condition called post-operative ileus, a malfunction of the intestines. The condition causes patients to become ill if they eat too soon, which can lengthen an affected patient’s hospital stay by two to three days. Until now, there was no way to monitor for post-operative ileus other than listening to the belly for short periods with a stethoscope, said study first author Dr. Brennan Spiegel, a professor of medicine at the David Geffen School of Medicine at UCLA and the UCLA Fielding School of Public Health.
If proven successful, the device, a non-invasive acoustic gastrointestinal surveillance biosensor called AbStats, could also be used to help diagnose irritable bowel syndrome and inflammatory bowel disease as well as helping obese people learn by the sounds from their gut when they should or shouldn’t eat, which could help them lose weight.
Spiegel and his team worked with researchers at the UCLA Wireless Health Institute at the Henry Samueli School of Engineering and Applied Science to develop the sensor, which resembles a small plastic cap and has a tiny microphone inside to monitor digestion.
“We think what we’ve invented is a way to monitor a new vital sign, one to go along with heart rate, blood pressure and respiration. This new vital sign, intestinal rate, could prove to be important in diagnosing and treating patients,” Spiegel said. “The role of wearable sensors in healthcare has reached mainstream consciousness and has the capacity to transform how we monitor and deliver care.
“Yet, there are very few biosensors that are supported by any peer-reviewed evidence,” Spiegel continued. “This study represents peer-reviewed evidence supporting use of a biosensor, a device born and bred out of UCLA multidisciplinary research.”
The study appears in the early online edition of the peer-reviewed Journal of Gastrointestinal Surgery.
In this study, the biosensor was used to listen to sounds emanating from the intestines and was connected to a computer that measured the rate of acoustic events — movement of the intestines — as they occurred. The research team compared intestinal rates of healthy subjects using the device for 60 minutes after a standardized meal to rates recorded in two post-operative groups, patients who were tolerating food and those that had post-operative ileus.
Using the biosensor, Spiegel and his team could distinguish patients with post-operative ileus from patients who did not suffer from the condition by the sounds made by their intestines. In the future, doctors may use the biosensor to determine which patients can be fed, making an evidence-based decision instead of just guessing based on less specific information, Spiegel said.
Spiegel hopes to be able to determine if the biosensor can be used to identify patients at risk for post-operative ileus to help doctors make post-operative feeding decisions.
“After surgery, the bowels shut down under stress as the body is focused on keeping the brain, heart and lungs alive,” Spiegel said. “We also give patients narcotic medications for pain that can also cause the bowels to freeze up. The way doctors currently monitor for POI is putting a stethoscope on the patient’s belly for 15 seconds, briefly listening for sounds of intestinal awakening, and asking about flatulence. It’s all very rudimentary and inaccurate. With this new vital sign, the team can now monitor the intestines empirically and make more informed decisions.”
When the bowels shut down, they become very quiet, moving only a few times per minute versus the digestion of a healthy person, who generates 10 or more intestinal movements per minute. The movements make a “clicking” noise, and it is that noise the biosensor picks up and sends to a computer for analysis.
William J. Kaiser, a professor of electrical engineering and co-director of the UCLA Wireless Health Institute, said development of the biosensor system has been a primary focus of the institute.
“It has been rewarding and exciting for our entire team. The institute develops wearable biomedical sensor systems to support our physician colleagues and fulfill our mission of advancing healthcare delivery,” Kaiser said. “The biosensor system is an important example of this rapid development that has resulted in a low-cost instrument that serves an unmet need for continuous, non-invasive monitoring of the human digestive processes. The biosensor can operate in the clinic, at home and at any location on the globe.”
Gastrointestinal disorders are highly prevalent in both inpatient and outpatient settings. A recent study commissioned by the National Institutes of Health found that there are more than 70 million ambulatory care visits every year in the U.S. with a gastrointestinal disorder listed as the first diagnosis. That number swelled to more than 100 million visits when gastrointestinal disorders were mentioned anywhere in the diagnosis, the equivalent of nearly 36,000 outpatient visits per 100,000 Americans.
Gastrointestinal disorders also have enormous direct and indirect societal costs, Spiegel said. The total direct cost of care for gastrointestinal disorders is estimated at $100 billion annually. Indirect costs increase that figure to more than $140 billion.
“With the aging of the American population and the rising incidence of obesity, it is certain that the economic impact of gastrointestinal disorders will get increasingly worse over the next decade and beyond,” Spiegel said.

- Professor Stanley Osher has been Awarded the Gauss Prize
Longtime UCLA professor earns highest honor in applied mathematics
Stuart Wolpert | August 12, 2014
Stanley Osher, UCLA professor of mathematics and director of applied mathematics, is the third person ever to be awarded the prestigious Gauss Prize, the highest honor in applied mathematics.
A UCLA professor since 1977, Osher received the award Wednesday afternoon local time during the opening ceremony of the International Congress of Mathematicians in Seoul, South Korea. The prize, named for 19th century mathematician Carl Friedrich Gauss, was first awarded at the 2006 congress. (The event is held every four years.)
The citation honoring Osher said he has made “influential contributions to several fields in applied mathematics and his far-ranging inventions have changed our conception of physical, perceptual, and mathematical concepts, giving us new tools to comprehend the world.”
Osher has collaborated with colleagues in a wide range of fields and the mathematical techniques he has pioneered have been highly influential. The results of his research have improved MRI scans and medical image analysis, advanced computer chip design, helped law enforcement agencies combat crime, enhanced computer vision, provided new ways to forecast weather and identify the source of earthquakes, and even revolutionized computer modeling for the design of supersonic jets.
“I am truly honored to have been awarded the third Carl Friedrich Gauss prize,” Osher said. “The previous winners were two of my scientific heroes. I am grateful to the UCLA administration and to my colleagues in the mathematics department for their support in building up applied mathematics, and to many of many colleagues outside of the department for the incredibly pleasant interdisciplinary research atmosphere that exists here.
“I’d also like to thank my sister, Sondra Jaffe, for convincing me that we could both join the middle class by becoming mathematicians in the post-Sputnik era.”
Osher has created innovative numerical methods to solve partial differential equations, and analyzed algorithms and their underlying partial differential equations. He also produced a new method for accurately describing how objects change shapes — predicting how, for example, a drop of oil floating in water will morph based on currents in the water, including what would happen if the drop of oil divided in two or merged with another drop of oil.
“Stan Osher is a superb applied mathematician who has made major advances in the solution of important real-world problems,” said Joseph Rudnick, senior dean of the UCLA College and dean of physical sciences. “His work is marked by elegance and efficiency. He richly deserves this important honor.”
The recipient of many previous awards, Osher was elected in 2005 to the National Academy of Sciences, and in 2009 to the American Academy of Arts and Sciences. He has been an Alfred P. Sloan Fellow and a Fulbright Fellow, and was selected to give a plenary address at the 2010 International Conference of Mathematicians and the John von Neumann Lecture at the 2013 meeting of the Society for Industrial and Applied Mathematics.
Osher was among the top 1 percent of the most frequently cited scholars in both mathematics and computer science between 2002 and 2012. His research was the subject of three-day “Osher Fests” at UCLA in 2002 and 2012.
He also the director of special projects at UCLA’s NSF-funded Institute for Pure and Applied Mathematics, where he has organized and participated in numerous workshops and programs.
Osher has trained and mentored more than 50 Ph.D. students and even more postdoctoral scholars, many of whom have become distinguished professors and researchers in applied mathematics. His students, one of whom received an Academy Award, have used mathematics to create special effects in dozens of movies, including “Pirates of the Caribbean.”
Osher said he is proud to be a professor at UCLA, whose applied mathematics department is ranked No. 2 in the U.S., per U.S. News and World Report, and whose pure mathematics department is also regarded among the best in the country.
He has said of his own research, “I write the algorithms that make the computer sing. I’m the Barry Manilow of mathematics.”

- Ultra Low-Power WiFi Reflector Link For Next Generation Embedded and Wearable Devices
While the advancing wearable devices market promises us a connectivity revolution in devices throughout our lives, conventional WiFi technology requires every device to carry a transmitter, a prospect which simply consumes too much power for a wearable or battery-free device to support.
UCLA researchers in collaboration with JPL have developed a WiFi reflector link over the last two years, which instead reflects existing WiFi signals present in the environment to communicate with a router or other WiFi source. As a wearable or other embedded device needs only reflect the WiFi signal, not generate it, the technology allows for connectivity at only 0.01% of the power consumption of a regular network link.
To date, JPL researchers Adrian Tang, Nacer Chahat and Rod Kim together with UCLA faculty Frank Chang have demonstrated reflector links up to 3 Mb/s at ranges of up to 2.5m in the laboratory. With more advanced signal processing, it is believed that such devices will eventually operate up to 20 meters with data rates comparable to existing WiFi connections (approx. 50 Mb/s).
- UCLA Engineering Plays Key Role in DARPA ‘Neuroprosthesis’ Research
Markovic, Sayed to Work on a $15 Million Project to Restore Memory Function to Victims of Brain Injury
The UCLA Henry Samueli School of Engineering and Applied Science has been tapped by the Defense Advanced Research Projects Agency to play a key role in an innovative project aimed at developing a wireless, implantable brain device that could help restore lost memory function in individuals who have suffered debilitating brain injuries and other disorders.
The four-year effort, to be led by UCLA's Program in Memory Restoration and funded by up to $15 million from DARPA, will involve a team of experts in neurosurgery, electrical engineering, neurobiology, psychology and physics who will collaborate to create, surgically implant and test the new "neuroprosthesis" in patients.
Dr. Itzhak Fried, a professor of neurosurgery at the David Geffen School of Medicine at UCLA and a professor of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience and Human Behavior at UCLA, is UCLA’s lead investigator on the project.
Dejan Markovic, associate professor of electrical engineering, will lead a group of UCLA Henry Samueli School of Engineering and Applied Science researchers developing technology to stimulate and record the activity of single neurons and of small neuronal populations. Electrical Engineering Professor Ali Sayed will work on signal processing and related aspects of the technology. DARPA will provide $4.5 million over four years for the UCLA Engineering effort, contingent on researchers meeting a series of technical milestones.
UCLA partners include the Lawrence Livermore National Laboratory and Stanford University.
Memory is the process by which neurons in certain brain regions encode, store and retrieve information. Various illnesses and injuries can disrupt this process, causing memory loss. Traumatic brain injury, which has affected more than 270,000 military members since 2000, as well as millions of civilians, is often associated with such memory deficits. Currently, no effective therapies exist to address the long-term effects of these injuries on memory.
This ambitious, first-if-its-kind project at UCLA builds on Fried's 2012 research demonstrating that human memory can be strengthened by stimulating the brain's entorhinal cortex, a region involved in learning, memory and Alzheimer's disease.
In a key part of the project, the research team will stimulate and record neuron activity in patients who already have brain electrodes implanted as part of epilepsy treatment. Researchers will use this information to develop computational models and determine how to intervene with electrical stimulation to help restore memory function. The models will be transformed into therapeutics using technology developed by Markovic‘s team.
Markovic said the goal is to create miniature wireless neural sensors that are far more sophisticated — much smaller and with much higher resolution — than those that exist today. The sensors will track and modulate neural activity with very precise spatial and temporal resolution, allowing the device to continuously update and modulate patterns of stimulation to optimize therapy and restore memory function.
“We are developing ultra–low-power electronics in order to measure activity of specific areas of the brain, perform neural signal analysis and wirelessly transmit that information to an outside device in close proximity to the implants,” Markovic said. “The implants and the outside device will talk to each other. The goals are to provide better therapy for people with neurological dysfunction and help those with epilepsy and brain injury to enhance and restore memory.”
During the second phase of the program, Fried, using a minimally invasive procedure, will implant the device in patients with traumatic brain injury as part of a groundbreaking clinical trial.
The DARPA initiative aimed at developing these implantable brain devices, Restoring Active Memory (RAM), supports President Obama's BRAIN initiative.

- Prof. Rob Candler is Awarded a $1 Million Grant by the W. M. Keck Foundation
Assistant Professor Robert Candler received a $1 million research grant from the W. M. Keck Foundation for his research entitled “Ultra-compact X-ray Free Electron Laser.” This is a 2-year endeavor which aims to produce a miniaturized free electron laser by combining novel nanofabrication techniques with cutting edge free electron laser physics, enabling access to new physical regimes of operation that are inherently more efficient. Partnering in this effort are Prof. Rob Candler from Electrical Engineering and the California NanoSystems Institute, Professor Pietro Musumeci from Physics, and Professor James Rosenzweig from Physics.
Currently there is only one x-ray laser device capable of producing high-speed and high-resolution imaging for use in chemistry, biology, material science and condensed matter physics, and it is only accessible from a billion dollar class national laboratory. The success of this study will lead to the creation of X-ray Free Electron Lasers (XFELS) that can fit in college laboratories and are capable of producing high brightness x-rays that generate ultrafast, high-resolution images in the x-ray water window. These miniature XFELS, will create a paradigm shift by making this tool for transformational science widely available to scientists.
The W. M. Keck Foundation funds distinct and novel research programs with promising and transformative impact that will advance technology and sciences for the preservation of life, access to innovative solutions and a better understanding of the world we live in.
- New Terahertz Modulator Could Lead to More Advanced Medical and Security Imaging
A UCLA Henry Samueli School of Engineering and Applied Science research team has developed a breakthrough broadband modulator that could eventually lead to more advanced medical and security imaging systems.
Modulators manipulate the intensity of electromagnetic waves. For example, modulators in cell phones convert radio waves into digital signals that the devices can use and understand. In terahertz-based communication and imaging systems, they modify the intensity of terahertz waves.
Today's technologies take advantage of many parts of the electromagnetic spectrum — notably light waves and radio waves — but they rarely operate in the terahertz band, which lies between infrared and microwave on the spectrum.
Led by Mona Jarrahi, UCLA associate professor of electrical engineering, the group developed a terahertz modulator that performs across a wide range of the terahertz band with very high efficiency and signal clarity. Among the device’s advantages are that it could easily be incorporated into existing integrated circuit manufacturing processes, can operate at room temperature and does not require an external light source to operate.
The terahertz band has been the subject of extensive research, in large part because of its potential for medical imaging and chemical sensing technologies. For example, terahertz waves could be used to examine human tissue for signs for disease without damaging cells or the other health risks posed by X-rays. They also could be used in security screenings to penetrate fabric or plastics that conceal weapons.
Current optical modulators that use naturally existing materials, such as silicon or liquid crystals, to manipulate the intensity of light waves have proven to be very inefficient in terahertz frequencies. And modulators based on artificial materials, so-called metamaterials, thus far have a limited use because they only operate in a narrow band of the terahertz range.
The new modulator is based on an innovative artificial metasurface — a type of surface with unique properties that is defined by the geometry of its individual building blocks, and their arrangement. The metasurface developed by Jarrahi's team is composed of an array of micro-electromechanical units that can be opened and closed using electric voltage. Opening or closing the metasurface encodes the incoming terahertz wave into a corresponding series of zeroes or ones, which are then transformed into images.
"Our new metasurface broadens the realm of metamaterials to broadband operation for the first time, and it diminishes many of the fundamental physical constraints in routing and manipulating terahertz waves, especially in terahertz imaging and spectroscopy systems," Jarrahi said. "Our device geometry can switch from an array of microscale metallic islands to an array of interconnected metallic loops, altering its electromagnetic properties from a transparent surface to a reflecting surface, which manipulates the intensity of terahertz waves passing through over a broad range of frequencies."
The research was published July 16 in the journal Nature Scientific Reports.
The study's lead authors are Mehmet Unlu and Mohammed Reza Hashemi, who were postdoctoral scholars in Jarrahi's group when she was a member of the faculty at the University of Michigan. Other authors are Christopher Berry and Shenglin Li, former students in Jarrahi's group, and Shang Hua Yang, a current UCLA graduate student.
The research was funded by the National Science Foundation's Sensor and Sensing Systems Division and an Army Research Office Young Investigator award.

- Professor John Villasenor Provides Congressional Testimony Regarding Digital Media Distribution
Over the last fifteen years, there have been fundamental shifts in how consumers access media. Internet-based distribution is now the norm, and content providers are increasingly shifting to license-based models in which consumers are licensees as opposed to owners of copies of digital books, songs, and movies. This raises important questions regarding the role of copyright law in the digital media ecosystem.
On June 2, the House Judiciary Committee convened a hearing to consider some of these questions. Professor John Villasenor was asked to be a witness at the hearing, and provided testimony on how potential changes to copyright law would impact the media distribution landscape. His testimony also addressed the growing role of contract law in governing the permitted and prohibited uses of the books, songs, and movies obtained over the Internet.
