Electrical engineers at the University of California, San Diego developed a receiver that can detect a weak, fast, randomly occurring signal. The study lays the groundwork for a new class of highly sensitive communication receivers and scientific instruments that can extract faint, non-repetitive signals from noise. The advance has applications in secure communication, electronic warfare, signal intelligence, remote sensing, astronomy and spectroscopy.
Researchers and students from UC San Diego's CISA3 presented a wide range of work at the annual Digital Heritage Conference in Granada, Spain, one of the top events worldwide for cultural heritage engineering.
Patients seeking rapid but safe weight loss have a new option at the Bariatric Metabolic Institute (BMI) at UC San Diego Health. During an outpatient procedure, surgeons place an adjustable saline balloon in the stomach. The volume and shape of the balloon take up space in the stomach, which encourages food portion control. The device, called Orbera, has been shown to reduce total body weight by 10 percent.
Five years ago, there were no computer science classes offered by schools within San Diego’s Sweetwater Union School District. Today, Sweetwater High School has a number of such classes, several of them Advanced Placement classes that encourage students to continue their education. That progress earned teacher Arthur Lopez, among others, and student Karla Gonzalez an invitation to meet with White House and National Science Foundation officials late last week.
Researchers at University of California, San Diego School of Medicine and University of Colorado Boulder have discovered that unique and changing microbial communities present during decomposition of human cadavers may provide a reliable “clock” for forensic scientists. The method could be used to estimate time of death in different seasons, as well determine the original location of moved corpses and help locate buried corpses.
When someone experiences a major stroke, almost two million nerve cells in the brain die each minute, emphasizing the need for rapid treatment. Stroke patients who receive life-saving interventions more quickly have a higher chance of recovery. A recent data analysis showed the Comprehensive Stroke Center at UC San Diego Medical Center exceeded national average treatment times, and as a result, has received a “Get With The Guidelines-Stroke Gold Plus Quality Achievement Award” from The American Heart Association and American Stroke Association (AHA/ASA).
