Using an ocular with 36 crossing lines, the frequency of the crossings covering bone tissue was recorded.
We present approximations of the probability density function of the elastic component and a similar expression to the Rice formula related to frequency of threshold crossings.
High frequency of grade crossings and difficulty of their elimination cause operational and safety challenges for increased train speeds in the U.S. [19].
The frequency of the crossings covering graft and newly formed bone tissue was recorded and expressed as a percentage of the total area measured.
The frequency of the crossings covering graft and newly formed bone tissue was recorded and expressed as a percentage of the total area measured (bone area/total area).
The high frequency of arteriovenous crossings in Nrp1 cytoΔ /Δ mutants raises the possibility that these mice could serve as an animal model to elucidate the poorly understood aetiology of BRVO.
A high frequency of arteriovenous crossings with an anterior position of the artery relative to the vein, combined with sharing of extracellular matrix by the crossed artery and vein, is a risk factor for BRVO (e.g. Weinberg et al., 1993; Zhao et al., 1993; Cahill and Fekrat, 2002).
In addition, the frequencies of crossing and non-crossing reaction norms for fitness indicate that in large populations divergent selection and local adaptation sensu Kawecki and Ebert [12] ("POS-POS" case) occurred in 52.3% of the cases (Fig. 2b) whereas in small populations this was much rarer (9.3%, Fig. 2b).
The frequencies of zero crossings and extrema can be related to the moments m k of the squared spectral amplitude, which are defined as: where Y f) is the spectrum corresponding to the seismological model given by Eq. (1).
The crossings section assessed crosswalks, slopes, width of crossings, crossing signals, and pedestrian protection (e.g., curb extensions, protected refuge islands).
