abstract in this study, trends of threshold heavy precipitation were examined on the basis of measurements of 1437 stations (included synoptic, climatic and rain gage stations) in iran for the period of 40 years (1964-2003). for this purpose, the statistical method of nonparametric mann-kendall test is used for analyzinging the thresholds of heavy precipitation and nonparametric sen method for ...
That area-sensitive songbirds breed only in relatively large patches suggests that there may be a minimum patch size threshold in which they will breed, even when controlling for the total amount of habitat in the landscape. We searched for minimum patch size thresholds of presence, territory establishment by males, pairing success, and reproductive success for 2 migratory songbirds that differ...
BACKGROUND Motivated by the challenges in assessing physician-level cancer screening performance and the negative impact of misclassification, we propose a method (using mammography as an example) that enables confident assertion of adequate or inadequate performance or alternatively recognizes when more data is required. METHODS Using established metrics for mammography screening performance...
Quantifying rainfall recharge thresholds, including their spatial and temporal heterogeneity, is of fundamental importance to better understand processes improving estimation rates. Caves provide a unique observatory into the percolation water from surface table at timescale individual events. Here, we monitor nine infiltration sites over six years montane cave site in south eastern Australia. ...
