Automatic beat tracking is challenging task, especially for audio music with time-varying meters. This study proposes a dynamic programming approach with positional weighting window to handle beat tracking with time-varying meters. In particular, the tempo curve is the reference to obtain correct beat positions. The weighting window is used to adapt bandwidth of tempo which reciprocal represent...

Arterial selection for reference time-enhancement curve generation in deconvolution-based perfusion CT (PCT) studies of the head and neck is under-evaluated. This study of 11 patients with confirmed head and neck squamous cell carcinoma demonstrates significant correlation (range, r = 0.85-0.95) between perfusion parameter values derived with internal carotid artery (ICA) as compared to an exte...

A phenomenological model based on the three-dimensional theory of nonlinear elasticity is developed to describe phenomenon overstretching in force-extension curve for double-stranded DNA (dsDNA). By using concept a material with multiple reference configurations single formula obtained fit curve.

We introduce a new file organization for the storage and manipulation of spatial (or multidimensional) data that is able to execute spatial join operations with great efficiency. The Filter Tree information structure is a hierarchical organization that tends to separate spatial entities by size, placing larger entities at the higher levels of the Filter Tree, and smaller entities at lower level...

PURPOSE We aimed to evaluate the value of CT tumor volumetry for predicting T and N stages of gastric cancer after chemotherapy, with pathologic results as the reference standard. METHODS This study retrospectively evaluated 42 patients diagnosed with gastric cancer, who underwent chemotherapy followed by surgery. Pre- and post-treatment CT tumor volumes (VT) were measured in portal venous ph...

Multi-sensor remote sensing data fusion technologies have been developed and widely applied in recent years, providing a feasible economical solution to increase the availability of high spatial temporal resolution data. These methods, however, challenging apply highly heterogeneous areas, especially complex agricultural landscapes where there are rapid changes at small scales, while features l...

The purpose of this study was to calculate and validate reference standards for the 20-m shuttle run test (SR) in youths aged 10-18 years. Reference standards based on the number of completed SR laps were calculated by LMS method in a reference group of 5559 students. Cut-off values for SR laps were determined and tested by ROC curve analysis in a validation group (633 students), from which wai...

Reference standards are used to calibrate similar assay systems against an international reference protocol and to provide a template for the preparation of secondary and/or working standards. Three reference standards are recommended for the indirect enzyme-linked immunosorbent assay: a strong positive standard, a weak positive standard and a negative serum standard. The negative standard shou...
