Database interconnection requires the development of links between related objects from different databases. We built a database of links, called Virgil, to manage and distribute rich (documented) links between GDB genes and GenBank human sequences. Virgil contains 18 667 unique links. In addition to a simple Web form for ad-hoc queries, we propose a generic Web interface and a prototype CORBA ...

We applied the respiratory sinus arrhythmia (RSA) quantification algorithm to 24-hour ECG recordings of Chagas disease (ChD) patients with (G1, n=148) and without left ventricular dysfunction (LVD) (G2, n=33), and in control subjects (G0, n=28). Both ChD groups displayed a reduced RSA index; G1=299 (144-812); G2=335 (162-667), p=0.011, which was correlated with vagal indexes of heart rate varia...

In this paper, we first note that Method III in Friedland, Nocedal, and Overton [SIAM J. Numer. Anal., 24 (1987), pp. 634–667] may not converge quadratically in the quotient sense. Then, we show that the method is convergent quadratically under a weaker notion of convergence — the root convergence. We also extend our results to the algorithm given in Chu [SIAM J. Numer. Anal., 29 (1992), pp. 88...

Significant investigation has taken place in the area of exploiting reconfigurable logic as a coprocessor in embedded and high-performance computer systems. This paper examines the problem of delivering high throughput data to the co-processor. Data is retrieved from magnetic storage and delivered to the coprocessor through datapaths available in inexpensive, commodity server platforms. Endto-e...

We present an update to the photometric calibration of the LASCO-C2 coronagraph onboard the SOHO spacecraft. We obtained the new calibration using data from the beginning of the mission in 1996 until 2013. We re-examined the LASCO-C2 photometric calibration by comparing the past three calibrations and the present calibration with the goal of validating an in-flight calibration. We find a photom...

The effects of selenium (Se)-biofortified corn on the total Se contents, the antioxidant enzyme levels, and the amino acids composition in Chinese mitten crab (Eriocheir sinensis) during the stage of the fifth shelling to maturity were investigated in the present study. The culture density of crabs was 600 per 667 m², and they were continuously fed 120.4 mg Se from Se-biofortified corn per 667 ...

OBJECTIVES The goal of this analysis was to test an algorithm that identifies implantable cardioverter-defibrillator (ICD) lead problems before clinical failure and/or inappropriate therapy. BACKGROUND The ICD lead failures typically present as inappropriate shock therapy. Identifying lead failures before their clinical presentation may prevent patient discomfort, improve device longevity, an...
