National (or regional) seismic hazard maps, determined from probabilistic seismic hazard analysis, quantify the expected intensity of shaking in a region(s) over the course of one or more desired time interval(s). Building codes use these maps to define the lateral force levels for the design of new and the retrofit of existing structures. In the past, the maps depicted the shaking intensity me...

BACKGROUND Illicit drug use is common and known to cause and exacerbate a wide spectrum of kidney disease, often leading to end-stage renal disease (ESRD), but little is known about its prevalence or associated mortality among incident hemodialysis patients. METHODS This study is a retrospective cohort analysis using data obtained from the United States Renal Data System. We assembled a cohor...

objectives: this study compared the effects of individual and group training on general health and stress of parents of children with autism spectrum disorders. methods: a sample of 75 parents of children referring to autistic children foundation (including 50 parents in two experimental groups and 25 parents in control group) was taken into account. sample parents were selected through accessi...

the degree kirchhoff index of a connected graph $g$ is defined as‎ ‎the sum of the terms $d_i,d_j,r_{ij}$ over all pairs of vertices‎, ‎where $d_i$ is the‎ ‎degree of the $i$-th vertex‎, ‎and $r_{ij}$ the resistance distance between the $i$-th and‎ ‎$j$-th vertex of $g$‎. ‎bounds for the degree kirchhoff index of the line and para-line‎ ‎graphs are determined‎. ‎the special case of regular grap...

1) quantile points at the selected times, S, corresponding to the expected probability and ± 1 SD (Table 1). The standard error in P rapidly decreases with increasing time after the mainshock due to the inclusion of current data. For example, at S = 1 day after the mainshock, the ± 1 SD range about the generic 1-day interval probability (0.052) is 0.034 to 0.075 (Table 1). Rydelek suggests esti...

A suggestion that protective eye gear can pose a threat either to the crystalline lens or to the retina is examined from an epidemiological point of view. It is concluded that it may accentuate a pre-existing high-risk hazard but has little significance for low-risk hazards.

We describe a framework for relating available data on hazards to impact on infrastructure. It is designed to be used by simulation platforms that may focus on a single infrastructure layer or aim to study interactions between interdependent layers. The Hazard Impact Framework (HIF) provides a flexible scheme for capturing and maintaining data on the response of elements of critical infrastruct...
