OBJECTIVES This study examines outcomes in a national sample of patients undergoing isolated aortic valve replacement (AVR) for aortic stenosis, with particular focus on advanced-age patients and those with extreme severity of comorbid illness (SOI). METHODS Data were obtained from the Nationwide Inpatient Sample and included all patients undergoing AVRs performed from January 1, 2006 to Dece...

This study involves a correlation between two measures of creativity: the Torrance Tests of Creative Thinking (TTCT) and the divergent production subtests of the Structure of Intellect Learning Abilities Test (SOI-LA). A population of 263 junior high school and senior high students from Louisiana were tested with both the TTCT and the SOI-LA. Results from the study indicate that the SOI-LA is a...

With the ultimate goal of creating autonomous microrobots, we have developed a new five-mask process that combines two polysilicon structural layers with 35 μm thick SOI structures and a backside substrate etch. The polysilicon layers provide 3D hinged structures, high compliance structures, and electrical wiring. The SOI structural layer yields much stronger structures and large-force actuator...

The Statistics of Income (SOI) Division of the Internal Revenue Service (IRS) produces data using information reported on tax returns. These administrative data are used by the Department of the Treasury, the Joint Committee on Taxation, and various Federal statistical agencies and are disseminated to the public via the World Wide Web and publications such as the SOI Bulletin. The Corporate For...

The present work considers electrothermal simulation of LDMOS devices and associated nonequilibrium effects. Simulations have been performed on three kinds of LDMOS: bulk Si, partial SOI and full SOI. Differences between equilibrium and nonequilibrium modeling approaches are examined. The extent and significance of thermal nonequilibrium is determined from phonon temperature distributions obtai...

In the literature frontal crashes typically have been classified as full, large overlap, or small overlap impacts (SOI) in accordance with the degree of frontal area involvement. These classifications implicitly refer to the degree of longitudinal structure engagement during impact. While full and large overlap impacts have received considerable attention, SOI has undergone limited analyses thr...

A correlation between the gated-diode R-G current and the performance degradation of SOI n-channel MOS transistor after F-N stress test has been demonstrated in this paper. Due to increase of interface traps after F-N stress test, the generation-recombination (R-G) current of the gateddiode in the SOI-MOSFET architecture increases while the performance characteristics of MOSFET transistor such ...

This paper describes applications of Silicon on Insulator (SOI) technology to high performance onchip memories (e.g. SRAMs and register files etc.).The primary focuses are on the important and unique issues in SOI technology such as performance gain, history effect, power reduction, pulsewidth control and self-heating. The effects on the interconnect performance and reliability are also discuss...

The southern oscillation index (SOI) is a characteristic of the El Niño phenomenon. SOI monthly averaged data is analyzed for the time interval 1866-2000. The tail of the cumulative distribution of the fluctuations of SOI signal is studied in order to characterize the amplitude scaling of the fluctuations and the occurrence of extreme events. Large fluctuations are more likely to occur than the...
