BACKGROUND The purpose of this study was to quantify the procedural rate and revision burden of total hip and knee arthroplasty in the United States and to determine if the age or gender-based procedural rates and overall revision burden are changing over time. METHODS The National Hospital Discharge Survey (NHDS) for 1990 through 2002 was used in(More)
This paper describes the early analysis and estimation features currently implemented in the Berkeley Emulation Engine (BEE) system. BEE is an integrated rapid prototyping and design environment for communication and digital signal processing (DSP) systems, consisting of four multiFPGA based processing units, each capable of emulating 10 million ASIC(More)
BACKGROUND Computed tomography (CT) scans are commonly used to diagnose acute diverticulitis, but there are overlapping features between diverticulitis and colorectal cancer (CRC) on imaging studies. Hence, colonoscopy is typically recommended after an episode of acute diverticulitis to rule out underlying malignancy. Currently, 64-slice multidetector CT(More)
Following diazoxide (DZ) induced hypoinsulinemia, cardiac luminal lipoprotein lipase (LPL) increases [Cardiovasc. Res. 3 (2003) 788]. To identify circulating mediators that maintain high LPL in vivo, DZ hearts were perfused for 1 h in the presence or absence of glucose, triglyceride (TG), palmitic acid or palmitoyl lysophosphatidylcholine (PLPC). Only PLPC(More)
During diabetes, impaired glucose transport and utilization by the heart switches energy production to exclusive beta-oxidation of fatty acid (FA). In the current study, we examined the contribution of cardiac lipoprotein lipase (LPL) towards providing FA to the diabetic heart. Streptozotocin (STZ) caused an augmentation of LPL activity at the coronary(More)
Urea is exploited as a nitrogen source by bacteria, and its breakdown products, ammonia and bicarbonate, are employed to counteract stomach acidity in pathogens such as Helicobacter pylori. Uptake in the latter is mediated by UreI, a UAC (urea amide channel) family member. In the present paper, we describe the structure and function of UACBc, a homologue(More)
A system-level perspective of a hierarchical automated design flow for low-energy direct-mapped signal processing integrated circuits is presented. Capturing design decisions in a dataflow graph allows push-button automation of layout and performance estimation. A detailed example of the design process for a DSSS TDMA baseband receiver is presented.
Acknowledgments This project is made possible by my advisor and many other facilities in the EECS department. They make a very challenging project available and I am very fortunate to be a part of it. This work would not be possible without the guidance of them. all the 60GHz members and many others make graduate life easier. They share all the joy and(More)
Previous research has introduced novel energy saving techniques such as the use of multiple VDD and VTH transistors, as well as transistor sizing, to limit storage energy and standby power. These techniques have been used to lower the power consumed in the non-critical paths of a design for a given performance specified by the critical path. In this report,(More)
The rapid proliferation of high bandwidth communications systems operating in low signal-to-noise ratio (SNR) environments continue to push systems designers to invent new algorithms that approach the Shannon capacity. The design and testing of these algorithms, whether in hardware or software has traditionally been a time consuming task especially as bit(More)
