Shear wave velocity is a basic engineering tool required to define dynamic properties of soils. In many instances it may be preferable to determine Vs indirectly by common in-situ tests, such as the Standard Penetration Test. Many empirical correlations based on the Standard Penetration Test are broadly classified as regression techniques. However, no rigorous procedure has been published for c...

The 61,020 samples of swine serum and vaginal swabs were collected in 2007-2009. The sera were examined by complement fixation test (CFT). Positive results were found in 277 pigs. The percentage of positive serological results in subsequent years was: 0.4%, 0.47%, and 1.65%, respectively. The vaginal swabs (n=277) selected from pigs diagnosed as positive in the CFT were tested by PCR. Occurrenc...

We studied the influence of the heart position in the thorax on the autocorrelation (AC) maps consisting of correlation coefficients between each pair of instantaneous electrocardiogram potential distributions over a time interval. We used a thorax-shaped electrolytic-filled tank with an isolated and perfused dog heart placed at positions spanning 5 cm on each space direction. The correlation c...

When common factors strongly influence two power-law cross-correlated time series recorded in complex natural or social systems, using detrended cross-correlation analysis (DCCA) without considering these common factors will bias the results. We use detrended partial cross-correlation analysis (DPXA) to uncover the intrinsic power-law cross correlations between two simultaneously recorded time ...
