Estimation of the setup accuracy of a surface image-guided stereotactic positioning system

Creator:: Meng, Lu Zheng
Abstract:: Purpose: Stereotactic radiation therapy and stereotactic radiosurgery deliver radiation precisely to tumors, using special equipment to position and demobilize patients. The VisionRT system, with its component AlignRT, is a non-invasive stereotactic positioning and tracking system that uses cameras to capture infra-red images of patients, and process these images, to obtain...

A low ground bounce CMOS off-chip driver design

Creator:: Zheng, Jieyin
Abstract:: With the advancement of technology, submicron CMOSonly process is available now for Application Specific Integrated Circuits (ASICs). The high integration leads to the need for high pin counts. However voltage supply and ground bounce due to many output drivers switching at the same time is becoming a major problem. In...

Radiometric ⁸¹Kr dating identifies 120,000-year-old ice at Taylor Glacier, Antarctica

Creator:: Buizert, Christo, Baggenstos, Daniel, Jiang, Wei, Purtschert, Roland, Petrenko, Vasilii V., Lu, Zheng-Tian, Mueller, Peter, Lee, James, Severinghaus, Jeffrey P., and Brook, Edward J.
Abstract:: We present the first successful ⁸¹Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four ~350 kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA). The ⁸¹Kr radiometric ages agree with independent...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

Contributions of ammonia-oxidizing bacteria and archaea to nitrification in forest soils

Creator:: Lu, Xinda
Abstract:: Prior to 2005, ammonia oxidation, the first step of nitrification, was thought mediated mainly by ammonia-oxidizing bacteria (AOB). However, the discovery of Thaumarchaeota carrying the genes coding for the ammonia monooxygenase (AMO) enzyme led to the discovery that ammonia-oxidizing archaea (AOA) also contribute to nitrification. Despite the uptick in studies...

EMD based hybrid models in short term traffic speed forecast

Creator:: Liu, Lu
Abstract:: Short-term freeway traffic speed prediction is essential to improving mobility and safety. It has been a challenging, yet unresolved issue. Traffic speed prediction can be applied to enhance the intelligent freeway traffic management and control for applications as operational and regulation planning. For example, with more reliable traffic speed prediction,...

The Impact of Commercial Insurance on Utilization and Cost of Healthcare Services among Patients with Cirrhosis

Creator:: Shi, Lu
Abstract:: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death in the United States. Patients with cirrhosis are more likely to develop HCC. More than 80% of HCC patients are found have preexisting cirrhosis. The prevalence of cirrhosis increased from 0.26% to 0.3.% between 1999 to 2010 and...

Biosynthetic engineering of new pactamycins

Creator:: Lu, Wanli
Abstract:: Among the myriad of naturally occurring bioactive compounds are the aminocyclopentitol-containing natural products that represent a family of sugar-derived microbial secondary metabolites, such as the antibiotics pactamycin, allosamidin, and trehazolin. Pactamycin, a structurally unique aminocyclitol antibiotic isolated from Streptomyces pactum, consists of a 5-membered ring aminocyclitol (cyclopentitol) unit, two aromatic...
