This case study presents the results of porting a production scientific code, called NAMD, to the SRC-6 high-performance reconfigurable computing platform based on field programmable gate array (FPGA) technology. NAMD is a molecular dynamics code designed to run on large supercomputing systems and used extensively by the computational biophysics community.(More)
This paper contains details on a project aimed to provide locationaware value-added services to the participants of an academic conference. The major characteristic of this project is the fusion of RFID technology, database management, data mining, real-time information visualization, and interactive web application technologies into an operational(More)
Human immunodeficiency virus type 1 (HIV-1) viral protein R (Vpr) is a 15kDa regulatory protein packaged in the HIV-1 virion. Although the molecular mechanism of Vpr function during viral replication remains elusive, Vpr has been found to possess interesting biological activities, including cell-cycle arrest at the G2/M check point, promotion of the HIV-1(More)
It is essential to identify any variant anatomy prior to surgery as this could have a drastic effect on surgical planning. We describe a case in which two vascular irregularities, an Arc of Buhler and celiac stenosis, were identified on angiogram after completion of a pancreaticoduodenectomy. While there could have been catastrophic results from his surgery(More)
BACKGROUND Three-dimensional (3D) digital photography uses integrated image capture technology and rendering software to create 3D models. Volumetric measurements project simulated post-operative images prior to breast augmentation. OBJECTIVES To evaluate the accuracy and reproducibility of breast volume measurements using the Portrait 3D Surgical(More)
The importance of the circadian/melatonin signal in suppressing the metastatic progression of breast and other cancers has been reported by numerous laboratories including our own. Currently, the mechanisms underlying the antimetastatic actions of melatonin have not been well established. In the present study, the antimetastatic actions of melatonin were(More)
Reconstruction following oncologic resection in the head and neck is complex due to large surgical defects left after removal of skin, subcutaneous, and skeletal structures. It is essential to adequately fill the defect as well as provide an acceptable tissue match in terms of tone, texture, thickness and contour. A 55-year-old male presented with an(More)
By design, the SRC-6 reconfigurable computer is programmed in the MAP C programming language within the framework provided by the SRC CarteTM development environment. The functionality of the original language can be extended via third party subroutines, called macros. These macros, typically implemented in Verilog Hardware Description Language, are brought(More)
The Extensible Sensor Platform (ESP) combines a sensor bus with a Software Defined Radio (SDR). The first field programmable gate array (FPGA) implementation of the ESP supports the Phillips Semiconductors IC sensor bus. The SDR provides the system with a programmable, flexible means of communicating sensor data over wireless data network available in a(More)
