Stent implants in stenosed arterial curvatures are prone to "Type IV" failures involving the complete transverse fracture of stents and linear displacement of the fractured parts. We present a protocol for detection of secondary flow (vortical) structures in a curved artery model, downstream of clinically relevant "Type IV" stent failures.

Source: Laboratory of Dr. B. Jill Venton - University of Virginia Calibration curves are used to understand the instrumental response to an analyte and predict the concentration in an unknown sample. Generally, a set of standard samples are made at various concentrations with a range than includes the unknown of interest and the instrumental response at each concentration is recorded. For more accuracy and to understand the error, the response at each concentration can be repeated so an error...

2023
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use. In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

2026
The secondary market is a vital part of the financial system, facilitating the trading of securities such as stocks and bonds after their initial issuance. It provides a platform where investors can trade shares initially issued through an initial public offering (IPO). In the United States, exchanges like the New York Stock Exchange (NYSE) and NASDAQ ensure that these transactions are conducted efficiently, offering liquidity and transparency.This market enables continuous trading of shares,...
FAQs
Slopes convert changes in a primary measurement into a rate-oriented view, allowing the analyst to examine how quickly a biological quantity changes rather than only its measured level. Changes in slope can expose shifts in process behavior that are difficult to recognize in the original plot. This perspective is especially useful for dynamic biological measurements.
Normalization changes the scale of primary measurements so researchers can examine values on a defined common basis. This may support comparisons among treatments or experimental measurements, but the calculation used for normalization affects what the resulting curve means. Stating the normalization method clearly helps readers distinguish a genuine biological pattern from a consequence of data transformation.
Replotting one measured variable against another can reveal relationships that are not apparent when either variable is viewed alone. The resulting curve may help researchers examine how biological measurements vary together under defined experimental conditions. Because the relationship depends on the selected variables and calculations, it should be interpreted as an analytical pattern rather than assumed to establish a cause.
Researchers should identify the primary measurements, the experimental conditions under which they were collected, and the calculation used to transform them. They may then select a slope, calculated rate, normalized value, or relationship between measured variables and replot the results. Recording these choices makes the secondary analysis traceable and supports consistent interpretation.
In growth studies, the analysis can emphasize changes across a biological process; for enzyme activity, it can help examine calculated activity-related patterns; and in dose-response work, it can support comparisons across treatments. Population-change studies provide another application. In each case, the secondary curve reorganizes measured results to highlight patterns relevant to the experimental question.
These analyses can help researchers compare treatments, estimate parameters, identify transitions, and evaluate experimental models. The specific outcome depends on the transformation and the quality of the primary measurements. A curve should therefore be read together with the original data and the calculation used to generate it, especially when interpreting apparent rate changes or model-related patterns.
